Why GAO Did This Study: 

As a result of the Internal Revenue Service (IRS) Restructuring and 
Reform Act of 1998, taxpayers facing liens or levies can request a 
Collection Due Process (CDP) appeal hearing with IRS’s Office of 
Appeals (Appeals). By 2005, CDP cases represented about one-quarter of 
Appeals’ workload. 

GAO was asked to provide information on (1) whether the IRS Collection 
function (Collection) erred in processing liens and levies and how 
often CDP case results changed after the appeal, (2) the arguments 
raised and the communication between IRS and taxpayers, (3) the 
characteristics of CDP taxpayers, and (4) potential improvements to the 
CDP program. To develop this information, GAO analyzed a random sample 
of 208 CDP cases closed by Appeals during fiscal year 2004. 

What GAO Found: 

GAO estimates that Appeals found Collection did not follow proper 
procedures in 2 percent of CDP cases closed during fiscal year 2004. 
About 27 percent of taxpayers received a different outcome than the 
lien filing or levy after appealing, including those that negotiated 
collection alternatives or ended up with no balance due to IRS. For 
about 60 percent of taxpayers, Appeals upheld the collection action 
often because taxpayers did not file all the required tax returns 
necessary to qualify for a collection alternative. 

GAO’s estimates show that nearly 90 percent of CDP taxpayers raised 
arguments permitted by statute with both Collection and Appeals, such 
as requesting a collection alternative. An estimated 5 percent of 
taxpayers raised frivolous arguments—arguments without legal basis per 
IRS guidance—with either Collection or Appeals. When taxpayers raised 
the same argument with Collection and Appeals, Appeals reached the same 
conclusion as Collection in more than 80 percent of cases. In general, 
the median number of IRS-initiated contacts with taxpayers was twice as 
high as the median number of taxpayer-initiated contacts with IRS. 

CDP taxpayer characteristics varied among individual and business 
filers. Both did not pay taxes for multiple return filing periods. 
Total tax liability varied considerably, with trust fund recovery 
penalty and employment tax cases having the highest liabilities. 

Allowing certain taxpayers like those that offer arguments without a 
legal basis to use the CDP program may not be consistent with the 
program’s goal of ensuring due process. Also, Appeals resources are not 
used efficiently when taxpayers request collection alternatives yet 
have not (1) submitted financial documentation with their CDP requests, 
(2) worked with specialized Collection units, or (3) filed all required 
tax returns needed to qualify for a collection alternative. IRS has 
taken steps to revise the CDP regulations and hearing request form, but 
has not established responsibility for analyzing program outcome data 
to determine if these changes will be effective.

What GAO Recommends: 

GAO makes recommendations to improve the efficiency of the CDP program. 
GAO also suggests that Congress consider amending the statute to remove 
CDP eligibility for selected categories of taxpayers if those 
taxpayers’ inclusion is not consistent with the goal of ensuring due 
process. IRS generally agreed with two recommendations but disagreed 
that it could require taxpayers seeking a collection alternative to 
submit additional information with their hearing requests. GAO then 
revised those recommendations to be a matter for congressional 
consideration.

Ranking Minority Member: 
Committee on Finance: 
United States Senate: 

In fiscal year 2005, the Internal Revenue Service (IRS) issued more 
than 3 million notices of federal tax liens and levies representing 
more than $10 million in delinquent taxes owed to IRS. The Internal 
Revenue Service Restructuring and Reform Act of 1998 (Restructuring 
Act)[Footnote 1] expanded the appeal rights available to taxpayers 
facing the filing of notices of federal tax liens or levies for the 
collection of delinquent taxes. With the passage of the Restructuring 
Act, Congress authorized the right to Collection Due Process (CDP) 
appeals, which provides taxpayers with an independent review of filed 
liens and levies by IRS's Office of Appeals (Appeals) and by the U.S. 
Tax Court or U.S. District Court. By 2005, taxpayers requesting CDP 
hearings accounted for more than one-quarter of the workload within 
Appeals, about 28,000 cases annually. IRS reported that in fiscal year 
2004, Appeals devoted about $8.2 million in salary costs to resolve CDP 
cases. 

Liens and levies arise when taxpayers fail to pay their taxes and IRS 
takes action to collect those outstanding tax liabilities. A lien is a 
legal claim against a taxpayer's property as security for the payment 
of the delinquent tax. A levy is a legal seizure of a taxpayer's 
property to satisfy the tax liability. Liens and levies identify the 
amount of tax owed by tax period, and the period varies by the type of 
tax. Individuals, for example, file individual income tax returns on an 
annual basis, so the period would equal 1 year. Businesses file certain 
tax returns, such as employment taxes, on a quarterly basis, so the 
period would equal 3 months. When IRS issues a Notice of Federal Tax 
Lien, Notice of Intent to Levy, or other notice related to automated 
levy programs,[Footnote 2] taxpayers are also informed of their due 
process rights, including the right to request a CDP hearing. IRS may 
include multiple delinquent tax periods in one notice. In their CDP 
appeals, taxpayers may raise issues related to the existence or amount 
of the liability; seek a collection alternative to the lien filing or 
levy, such as an installment agreement (IA)[Footnote 3] or offer-in- 
compromise (OIC);[Footnote 4] or both. 

Based on your request, this report's objectives are to provide 
information on (1) the extent to which Appeals found the IRS Collection 
function (Collection)[Footnote 5] had made errors in processing liens 
and levies and how often CDP case results changed after a taxpayer 
requested a CDP appeal hearing; (2) the nature of the arguments 
presented by taxpayers seeking relief from liens or levies and the 
amount of communication between IRS and taxpayers; (3) the 
characteristics of the taxpayers that availed themselves of the CDP 
appeal process, such as the amount of their total liabilities; and (4) 
whether opportunities exist to improve the operations of the CDP 
program while protecting taxpayer rights. 

To develop the information for these objectives, we analyzed a random 
sample of 208 CDP appeal cases, drawn from a population of 32,241 cases 
closed by Appeals during fiscal year 2004. For each of the cases in our 
sample, we requested the Appeals closed office file and reviewed the 
documentation in the files to determine case characteristics, such as 
the ultimate outcome of the CDP appeal process. We also requested the 
Collection administrative file associated with each of our sample CDP 
cases to assess what transpired between the taxpayer and IRS after 
Collection issued the notice of a lien filing or levy. We supplemented 
the information obtained through documentary case file review with 
information from IRS databases. We used the results of our case file 
review to make estimates for the entire population of taxpayers whose 
CDP appeal cases were closed by Appeals during fiscal year 2004. Since 
our estimates are based on a sample, we express our confidence in our 
estimates as a 95 percent confidence interval, plus or minus a margin 
of error, which is the interval that would contain the actual 
population value for 95 percent of the samples we could have selected. 
Unless otherwise stated, we express our particular sample's results as 
a 95 percent confidence interval, less than plus or minus 8 percentage 
points. In some instances, we report our sample estimates as medians. 
All medians based upon the results of our sample have a relative 
standard error of less than 30 percent unless otherwise 
stated.[Footnote 6] In addition, we reviewed IRS program guidance on 
the CDP process and interviewed knowledgeable agency officials. We also 
interviewed representatives from other external stakeholder 
organizations knowledgeable about the CDP appeal process. We conducted 
our review from January 2005 through September 2006 in accordance with 
generally accepted government auditing standards. (See app. I for a 
more detailed description of our scope and methodology.) 

Results in Brief: 

Our review of CDP cases closed in fiscal year 2004 indicates that 
Appeals found evidence in a small percentage of cases that Collection 
erred in handling taxpayer cases. As shown in figure 1, we estimate 
that in about 2 percent of CDP cases Appeals concluded that Collection 
had not followed proper procedures. Although Appeals did not identify 
any instances in our sample where the applicable legal and 
administrative procedural requirements were not met, our case file 
review did identify instances where Appeals detected other types of 
procedural errors during the collection phase of the cases, which we 
included as evidence of detection of improper procedures. Nevertheless, 
even if some taxpayers received a different outcome after appealing to 
IRS, Appeals did not necessarily disagree with the lien filing or levy. 
In an estimated 27 percent of CDP cases, taxpayers received a different 
outcome after they appealed the lien filing or levy, including those 
that (1) negotiated collection alternatives, such as IAs (16 percent), 
and (2) fully paid their liabilities or no longer had balances due to 
IRS (11 percent). In addition, in approximately 11 percent of CDP 
cases, taxpayers formally withdrew their CDP appeal requests. Finally, 
in an estimated 60 percent of CDP cases, Appeals upheld the lien filing 
or levy and did not reach a different result for taxpayers often 
because those who sought collection alternatives were not eligible for 
an alternative. They were not eligible because they had not filed 
required returns, had not paid certain taxes, or both. Other major 
reasons for no change upon appeal were that Appeals determined the 
amount of the liability to be correct, the taxpayer had not responded 
to Appeals' request for information, or both. An estimated 2 percent of 
all taxpayers that requested CDP appeals hearings disputed the Appeals 
determination and petitioned the U.S. Tax Court or U.S. District Court.

[End of figure] 

Taxpayers seeking relief from liens or levies generally raised 
allowable arguments to claim they did not owe some or all of the tax or 
to seek collection alternatives. More than 90 percent of these 
taxpayers had raised one or more legally allowed arguments permitted by 
the Restructuring Act for CDP hearings with both Collection and 
Appeals. When challenging the lien filing or levy, about 37 percent of 
taxpayers questioned the existence of the tax liability. Almost one- 
third of taxpayers requested collection alternatives, such as OICs. In 
addition, more than one-quarter of taxpayers questioned the 
appropriateness of the collection action, for example, raising personal 
hardships arguments such as illness or bankruptcy. An estimated 5 
percent of taxpayers raised frivolous arguments--arguments without 
legal basis per IRS guidance--with either Collection or Appeals. When 
taxpayers raised the same arguments with Collection and Appeals, 
Appeals reached the same conclusions as Collection that the taxpayers' 
argument lacked merit in an estimated 81 percent of the cases. When 
Appeals reached a different conclusion it was for reasons such as the 
taxpayer not providing requested information or providing different 
information to Appeals than to Collection. After IRS issued the lien 
filing or levy notice, IRS (Collection and Appeals) had various types 
of contacts with the taxpayer in the effort to resolve the liability. 
IRS sent a median of 3.6 letters and made a median of 3.2 phone calls. 
IRS had face-to-face contact with about 28 percent of taxpayers. In 
general, the median number of IRS-initiated contacts with taxpayers was 
twice as high as the median number of taxpayer-initiated contacts with 
IRS. 

Both individuals and businesses that receive lien or levy notices can 
exercise their due process rights to CDP appeals. Most taxpayers that 
requested CDP appeals--about 87 percent--were individuals, the 
remaining 13 percent of taxpayers were businesses. Both business and 
individual taxpayers were delinquent (did not pay taxes) on multiple 
periods. Businesses with employment tax liabilities were delinquent on 
more than twice as many periods--nearly six quarterly periods on 
average--while individuals with income tax liabilities were delinquent 
for approximately three annual periods on average. In calendar terms, 
this means that on average businesses that requested a CDP appeal for 
delinquent employment taxes had not paid for nearly 1-½ years, while 
individuals were delinquent on paying their income taxes for 3 years. 
Total tax liability also varied considerably, with trust fund recovery 
penalty cases having the highest median liability amount followed by 
employment tax cases. For example, individuals' median total trust fund 
recovery penalty tax liability appealed was nearly $45,000, while the 
median for total employment tax liability was about $30,000. The total 
median liability for individuals with income tax cases was nearly 
$13,000. Over half of all individual taxpayers who requested CDP 
appeals had most recently reported an adjusted gross income of less 
than or equal to $50,000 prior to their appeals. Overall, taxpayers 
chose to represent themselves before Appeals about 56 percent of the 
time, although individuals represented themselves more often, about 61 
percent of the time. 

The results of our case file review and interviews with IRS officials 
have raised concerns about whether certain types of taxpayers have used 
the CDP program in a manner that may be inconsistent with the goal of 
ensuring due process. Our case file review enabled us to provide 
quantitative estimates on the extent to which these certain situations 
were present among CDP cases closed by Appeals during fiscal year 2004. 
Neither the law nor the legislative history makes any distinctions with 
respect to the type of taxpayer, type of tax liability, or method of 
liability determination that was intended to be included in due process 
appeal cases. Rather, the Restructuring Act permits any taxpayer who 
receives a lien or levy notice to request a CDP hearing. However, since 
implementation of the program, some concerns have been expressed 
regarding potential abuse. Cases of concern include those where 
taxpayers may not have been serious about working with Appeals because 
they offered frivolous arguments in their appeals (about 4 percent for 
cases closed in fiscal year 2004)[Footnote 7] or did not respond or 
responded only initially to Appeals (about 20 percent). Some taxpayers 
questioned the existence or amount of the liabilities (about 38 
percent) even though the majority did not claim that they were not 
properly notified. Other taxpayers self-reported their tax liabilities 
and therefore were aware of their outstanding obligations to IRS (about 
47 percent). Other taxpayers that contested collection of either 
employment or unemployment taxes (about 13 percent) had often failed to 
pay their taxes for long periods of time. Because the law makes no 
distinctions in this regard, these concerns cannot be addressed through 
regulatory changes. 

IRS also raised concerns that other types of cases have resulted in an 
inefficient use of Appeals' resources. These include cases where 
taxpayers that requested OICs or IAs did not submit overdue tax 
returns, provide supporting financial information, or provide the OIC 
application form (if appropriate) necessary for Appeals to consider 
their requests. In these cases, Appeals staff had to devote time to 
getting taxpayers to file required returns and obtaining basic 
financial information necessary to determine whether the taxpayers were 
even eligible for either of these alternatives. One option in these 
situations would be to require taxpayers that request only a collection 
alternative to provide the necessary supporting financial information 
or OIC application form (if appropriate) within a set period and 
proceed to make a final case determination at that time on the basis of 
the information available. In addition, some taxpayers requesting OICs 
from Appeals had not previously worked with IRS's specialized unit that 
was established to screen and process OICs quickly and efficiently. IRS 
also raised concerns that Appeals spent time attempting to bring 
taxpayers into filing compliance--that is, securing delinquent returns 
from taxpayers--in order to assist taxpayers in meeting the most basic 
eligibility criterion for either an OIC (about 23 percent were 
ineligible because of noncompliance) or IA (about 21 percent were 
ineligible because of noncompliance). Although the Restructuring Act 
does not specifically address this issue, IRS officials said that a 
statutory change would be needed to require taxpayers to file all the 
required returns before transferring cases to Appeals for review. IRS 
has proposed making changes to the CDP hearing request form as well as 
to the regulations that govern the CDP program. The proposed changes to 
the regulations are intended to clarify processes generally related to 
requesting and conducting a CDP appeal hearing, as well as to clarify 
what issues or arguments taxpayers may raise. Although these changes 
may improve the CDP program, IRS has not established responsibility for 
analyzing future CDP program outcome data in order to determine if 
these changes will result in achieving the desired objectives. 

While the proposed revisions to CDP regulations may improve program 
operations, additional operational changes not addressed in the 
regulations may help achieve further efficiencies. To that end, this 
report includes three recommendations to IRS to help ensure that 
Appeals' resources are more efficiently devoted to its mission of 
resolving disputes by (1) determining--for taxpayers seeking only a 
collection alternative--a reasonable amount of additional time beyond 
the current 30-day period for requesting a CDP hearing for these 
taxpayers to submit the required supporting financial information 
necessary for Appeals to consider the alternative of choice, and the 
OIC application form if appropriate; (2) instructing Appeals to 
transfer OIC cases to IRS's specialized processing unit for 
investigation and evaluation of OICs before consideration by Appeals; 
and (3) establishing responsibility for analyzing CDP appeal case 
outcome data in order to determine whether revisions to the hearing 
request form and program regulations result in meeting their 
objectives. This report also includes three matters Congress should 
consider to help ensure CDP appeal hearings meet the goal of ensuring 
due process to taxpayers while excluding certain specific categories of 
taxpayers or issues that Congress may now deem to be inconsistent with 
that intent. Specifically, Congress should consider (1) amending the 
statute to remove eligibility for CDP appeal for selected categories of 
taxpayers if it judges that that taxpayers have characteristics deemed 
inconsistent with the Restructuring Act's goal of providing due 
process; (2) amending the statute to require taxpayers seeking 
collection alternatives such as OICs or IAs and that raise no other 
issues to meet the basic eligibility criteria, that is, file all 
outstanding tax returns due, before Appeals reviews the case; and (3) 
requiring taxpayers that raise only collection alternatives to submit 
the supporting financial information needed to consider the alternative 
of choice, and the OIC application form if appropriate, within a 
reasonable amount of time following the request for a CDP hearing. 

In commenting on a draft of this report, the Commissioner of Internal 
Revenue agreed that our recommendation on transferring cases where 
taxpayers request OICs as a collection alternative to one of IRS's 
specialized processing units for consideration before Appeals considers 
the cases merited further study. IRS also agreed with the 
recommendation to establish responsibility for evaluating CDP outcome 
data to assess whether changes to the hearing request form and proposed 
regulation changes are effective. IRS did not agree with our draft 
recommendations that it should require taxpayers seeking collection 
alternatives to submit supporting financial information with their CDP 
appeal hearing request or requiring taxpayers seeking an OIC to submit 
the OIC application form because it lacks the authority to do so. In 
response to IRS's concerns, we revised our recommendations to present 
these issues as a matter for congressional consideration. In the event 
that Congress decides to take action on this matter, we added a 
recommendation to the agency. Specifically, IRS should determine the 
reasonable amount of additional time that taxpayers seeking collection 
alternatives should be allowed in order to provide the supporting 
financial information and OIC application form (if appropriate) 
following their CDP hearing requests. 

Background: 

When Congress passed the Restructuring Act, it created new and expanded 
taxpayer rights, including the right to CDP hearings and judicial 
review to challenge IRS's liens and levies. IRS's Collection Appeals 
Program (CAP), established before the Restructuring Act, allows 
taxpayers to appeal several IRS collection actions. However, taxpayers 
that do not agree with CAP's determination cannot go to court because 
CAP's decisions are not subject to judicial review. According to a 
Senate Finance Committee report, CDP was intended to afford taxpayers 
with protection from IRS collection methods similar to the protection 
they have in dealing with any other creditor. The report stated that 
IRS should provide taxpayers with adequate notice of collection 
activity and a meaningful hearing.[Footnote 8] 

IRS issues several different types of collection notices that also 
inform taxpayers of their due process rights, including the right to 
request a CDP hearing. IRS issues a Notice of Federal Tax Lien (lien 
notice) to establish the priority of the tax lien over other liens 
against the taxpayer's assets for the amount of unpaid tax 
liability.[Footnote 9] IRS issues a Notice of Intent to Levy (levy 
notice) to inform taxpayers that failure to pay their tax liabilities 
could result in an IRS levy on the taxpayers' assets held by financial 
institutions or other parties.[Footnote 10] Lien or levy notices may be 
issued by IRS's Automated Collection System (ACS) or Collection Field 
Function (Field Collection).[Footnote 11] Taxpayers may also request 
CDP hearings in response to notices received related to automated levy 
programs, specifically the State Income Tax Levy Program (SITLP), the 
Federal Payment Levy Program (FPLP), or the Alaska Permanent Fund 
Dividend (PFD) Program.[Footnote 12] In addition, some taxpayers 
request and receive CDP hearings based on multiple due process 
collection notices, such as a combination of lien and levy notices. 
Taxpayers are given a CDP hearing after a levy on a state income tax 
refund, and a levy is issued when the IRS finds collection of the tax 
is in jeopardy. 

Any taxpayer that receives a lien or levy notice has the right to 
dispute the action by filing a written request for a CDP hearing within 
30 days of the date of the notice. Taxpayers that file for CDP hearings 
within the 30-day period are granted hearings with a right to judicial 
review from the U.S. Tax Court or U.S. District Court if they do not 
agree with Appeals' determination. Taxpayers that file a request for 
CDP hearings after the 30-day period will be given an equivalent 
hearing (EH), but have no right to judicial review. Once IRS receives a 
CDP hearing request, all tax collection efforts are generally suspended 
until Appeals issues its determination to the taxpayer. Under the EH 
process, IRS may continue to enforce collection efforts although IRS's 
policy is generally to suspend collection during an EH. Interest and 
penalties continue to accrue during the hearing period for both EH and 
timely CDP hearings. 

By statute, during CDP hearings, taxpayers may raise issues related to 
(1) the appropriateness of the lien filing or levy; (2) offers of 
collection alternatives, such as IAs, OICs, and posting bonds or 
substitution of other assets; (3) appropriate spousal defenses; and (4) 
challenges to the existence or amount of the tax, but only in cases 
where they did not receive statutory notice of deficiency[Footnote 13] 
or did not otherwise have an opportunity to dispute the tax liability. 
The Internal Revenue Manual allows the taxpayer to raise issues related 
to a hardship determination.[Footnote 14] However, a taxpayer may not 
raise an issue that was raised previously and considered at a prior 
administrative or judicial hearing if the taxpayer participated 
meaningfully in that hearing or proceeding. 

Once IRS receives a CDP request, Collection attempts to work with the 
taxpayer for approximately 45 to 90 days to resolve the issue prior to 
transferring the case to Appeals. If Collection is successful in 
resolving the case with the taxpayer, the taxpayer can formally 
withdraw from CDP. When Collection is unsuccessful in resolving the 
case with the taxpayer, it forwards the case file to Appeals for its 
independent review. However, in certain situations, Collection 
immediately forwards the taxpayer's case to Appeals, such as when 
collection alternatives have already been explored and discussions are 
at an impasse, the taxpayer raises frivolous or constitutional issues, 
the taxpayer appears to be using CDP as a delaying tactic because the 
taxpayer is not responding to requests for information, or the taxpayer 
does not want to work with Collection after requesting the CDP hearing. 

Appeals' mission is to independently resolve tax disputes prior to 
litigation on a basis that is fair and impartial to both the government 
and the taxpayer. By statute, when Collection forwards the case to 
Appeals, Appeals will (1) verify that the requirements of any 
applicable law and administrative procedures have been met, (2) 
consider any relevant issues relating to the unpaid tax or the levy, 
and (3) determine whether any lien filing or levy balances the need for 
the efficient collection of taxes with the legitimate concern of the 
taxpayer that any collection be no more intrusive than necessary. 
Appeals then renders a decision on the case in which it may either 
agree that the lien filing or levy is appropriate (that is, "sustain" 
or uphold the collection action) or not appropriate (that is, "not 
sustain" the collection action). Appeals may also include in its final 
determination a description of the terms for any collection alternative 
negotiated with the taxpayer, such as an OIC or IA. 

As shown in figure 2, the volume of CDP case closures has increased 
steadily from the inception of the CDP program from fiscal year 1999 
through fiscal year 2004 and then declined in fiscal year 2005. In 
fiscal year 2005, CDP cases accounted for more than one-quarter of 
Appeals' annual caseload.

CDP Appeals Identified Few Errors by Collection, but Some Taxpayers 
Received a Different Outcome: 

Our case file review indicates that during the CDP review process 
Appeals found evidence that Collection had not followed proper 
procedures in an estimated 2 percent of the cases closed in fiscal year 
2004. For reasons unrelated to an error by Collection, in an estimated 
27 percent of cases, taxpayers emerged from the CDP hearing process 
with a different outcome than the lien filing or levy action. Of these, 
Appeals agreed to a collection alternative for an estimated 16 percent 
of all taxpayers, and approximately 11 percent of all taxpayers fully 
paid their tax liabilities or no longer had balances due to IRS. In 
addition, an estimated 11 percent of all taxpayers withdrew from the 
CDP process. Finally, in about 60 percent of cases, Appeals upheld the 
lien filing or levy for a variety of reasons, including because 
taxpayers did not file required returns, had not paid their taxes for 
certain periods, or both. 

Appeals Rarely Found Evidence of Procedural Errors by Collection: 

As previously shown in figure 1, Appeals found evidence that Collection 
had not followed proper procedures in an estimated 2 percent of CDP 
cases. Although Appeals did not identify any instances in our sample 
where "requirements of applicable law and administrative procedure" 
were not met,[Footnote 15] our case file review did identify instances 
where Appeals detected other types of procedural errors during the 
collection phase of a case. For example, in one case IRS misapplied a 
payment to the taxpayer's ex-spouse. Appeals reapplied the payment to 
the taxpayer's account and did not uphold the lien filing and levy 
because there was no balance due. We included these types of cases in 
our estimation of procedures not followed as they represented other 
examples of situations where taxpayers utilized the CDP appeal process 
consistent with the provisions of the Restructuring Act--that is, as an 
opportunity to correct any errors made by Collection. 

Of approximately 27 percent of CDP cases that resulted in a different 
outcome after taxpayers appealed, Appeals negotiated a collection 
alternative with taxpayers in about 16 percent of the cases. However, 
when Appeals negotiates a collection alternative, it is not necessarily 
disagreeing with the lien filing or levy. Appeals may accept a 
taxpayer's collection alternative but sustain the filing of the lien in 
order to protect the government's lien priority in the event of 
default. In addition, taxpayers may present Appeals with new 
information not previously provided to Collection for consideration. 
For example, in one of our cases, the taxpayer requested an IA with 
both Collection and Appeals. After submitting requested financial 
information and a down payment with Appeals, the taxpayer qualified for 
an IA. The taxpayer benefited from the CDP process by negotiating a 
collection alternative with Appeals. In an estimated 11 percent of all 
CDP cases, Collection's lien filing or the levy was no longer 
appropriate because the taxpayer had since fully paid the liability or 
had no balance due. In these cases, the lien or levy was no longer 
necessary because the taxpayer no longer owed any tax to IRS. Appeals 
officials stated that some taxpayers file for CDP to delay imminent 
collection action while they find revenue sources to pay off their 
unpaid liabilities. For example, one taxpayer in our sample obtained a 
loan during the hearing process to fully pay the liabilities owed. 

In addition, in about another 11 percent of all CDP cases, taxpayers 
withdrew from the CDP process after their cases reached Appeals, so 
Appeals neither upheld nor overturned the liens or levies. For example, 
one taxpayer continued to work with Collection while the case was 
transferred to Appeals. Collection negotiated an IA with the taxpayer, 
and then the taxpayer withdrew the CDP request from Appeals. We did not 
track the final outcome of cases after taxpayers withdrew from the CDP 
hearing process. 

Of all CDP cases, approximately 6 percent of taxpayers negotiated a 
collection alternative while in Collection but failed to formally 
withdraw from the CDP program, resulting in their cases being forwarded 
to Appeals. According to Appeals officials, in these situations Appeals 
will generally agree with the proposed collection alternatives unless 
the taxpayers' situations change so much that they can no longer comply 
with the agreements reached with Collection. Appeals officials also 
said that some professional representatives advise clients not to 
withdraw from CDP even though they resolved the issue at the Collection 
level because they want to preserve their clients' right to judicial 
review. 

Appeals Upheld the Majority of Liens and Levies, Often Because of 
Taxpayer Noncompliance: 

In an estimated 60 percent of cases where Appeals determined the lien 
or levy was appropriate, Appeals upheld the lien filing or levy 46 
percent of the time because Appeals determined that taxpayers did not 
comply with filing requirements, did not pay their liabilities for 
certain tax periods, or both, as shown in table 1. For example, to be 
eligible for an OIC, a business taxpayer must file all required federal 
tax returns, file and pay any required employment taxes on time for the 
two quarters prior to filing the OIC, be current with deposits for the 
quarter in which the OIC was submitted, pay any required estimated tax 
for the current period, and not be a debtor in a bankruptcy case. To be 
eligible for an IA, an individual taxpayer must file all required tax 
returns currently due and make all required estimated tax payments on 
the current period prior to the commencement of the IA. 

Table 1: Reasons Why Appeals Upheld the Lien Filing or Levy for Cases 
Closed in Fiscal Year 2004:

payment, or both;

[End of table] 

In addition to noncompliant taxpayers, Appeals upheld the lien filing 
or levy for a variety of other reasons, including when taxpayers 
questioned the amount of the tax liability but Appeals determined the 
liability to be correct (an estimated 38 percent) and when taxpayers 
did not respond to Appeals (an estimated 30 percent). With respect to 
nonresponsive taxpayers, Appeals officials stated that they attempt to 
communicate with taxpayers at least twice by correspondence before 
issuing determination letters. 

About 2 percent of all taxpayers that requested CDP appeal hearings 
contested the Appeals determination in the U.S. Tax Court or U.S. 
District Court. Officials in IRS's Office of Chief Counsel said that 
based on their experience with docketed cases, Appeals is upheld a 
majority of the time. When the courts overturn the Appeals 
determination, IRS Chief Counsel officials said that it does not 
necessarily mean that Appeals erred. Some taxpayers provide additional 
or new information considered by the courts but not presented to 
Appeals, leading to reversed decisions. 

The Majority of Taxpayers Raised the Same Arguments with Both 
Collection and Appeals, Received the Same Determination, and Had 
Multiple Contacts with IRS: 

During fiscal year 2004, most taxpayers raised arguments permitted by 
statute to Appeals, while we estimated that 5 percent of taxpayers 
raised arguments considered frivolous under IRS guidance with either 
Collection or Appeals.[Footnote 16] When a taxpayer raised the same 
argument in both Collection and Appeals, in an estimated 81 percent of 
the cases Appeals agreed with Collection on the merits of the 
taxpayer's argument. During the CDP process, Collection and Appeals 
initiated multiple communications with the taxpayer, including letters, 
telephone discussions, and face-to-face meetings. 

Most Taxpayers Raised Permissible Arguments, but Some Presented 
Frivolous Arguments: 

Taxpayers raised various arguments permitted by the Restructuring Act 
in more than an estimated 90 percent of CDP cases. After their cases 
were transferred to Appeals, about 41 percent of taxpayers requested an 
OIC and about 37 percent of taxpayers requested an IA. Less than 3 
percent of taxpayers requested innocent spouse relief as permitted 
under the Restructuring Act during their CDP hearings in Appeals. 

Approximately 38 percent of taxpayers questioned the existence of the 
tax liability. Under the Restructuring Act, a taxpayer may challenge 
the existence or dollar amount of the tax liability at the CDP hearing 
if the taxpayer did not receive a statutory notice of deficiency for 
the liability or did not otherwise have an opportunity to dispute the 
tax liability. Seven out of the 80 taxpayers in our sample challenging 
the existence of a liability claimed they did not receive the statutory 
notice of deficiency. The remaining 73 out of the 80 taxpayers raised 
existence of the liability for a variety of other reasons, including 
contesting the amount of the liability. One Appeals official suggested 
that some taxpayers without professional representation (pro se) may 
not understand the definition of questioning "the existence or amount 
of the liability" under the Restructuring Act. IRS has drafted a 
revised CDP appeal hearing request form in an effort to assist 
taxpayers in determining what types of collection alternatives are 
available and what types of arguments are allowed. The revised hearing 
request form is intended to more clearly explain what it means to 
dispute the existence or amount of the liability and the taxpayer's 
ability to question the liability under CDP. 

While their cases were in Appeals, an estimated 38 percent of taxpayers 
questioned the appropriateness of the lien filing or levy and presented 
hardship arguments. According to guidance issued by IRS Counsel, 
taxpayers may argue that a lien or levy is inappropriate because 
payment would cause hardship, for example, if the taxpayer has no 
disposable income or assets. The primary hardship issue taxpayers cited 
during the CDP process was illness (about 11 percent). Other hardship 
issues taxpayers reported included bankruptcy, unemployment, and death 
in the family. 

An estimated 5 percent of taxpayers requesting a CDP appeal presented a 
frivolous argument to either Collection or Appeals. According to IRS, 
taxpayers raising frivolous issues consume a disproportionately large 
amount of time because Appeals personnel must often read lengthy 
frivolous submissions in search of any substantive issue that might be 
contained within the case file. In addition, according to IRS, delays 
result when taxpayers use face-to-face meetings as a venue for 
frivolous oration and harassment of Appeals personnel. IRS has proposed 
changes to the CDP regulations, which clarify that Appeals will not 
offer face-to-face meetings if the taxpayers or their representatives 
raise only frivolous arguments.[Footnote 17] However, representatives 
from an external stakeholder group expressed concerns that IRS may 
misclassify cases as frivolous and deny face-to-face meetings although 
the taxpayer is raising arguments permitted under the Restructuring 
Act. For example, one stakeholder suggested that a pro se taxpayer's 
argument may be misclassified as frivolous if the taxpayer uses the 
word protest on the CDP request form. Prior to the Restructuring Act 
IRS could designate certain taxpayers, such as those using arguments 
that had been repeatedly rejected by the courts, as "illegal tax 
protesters." As a result, taxpayers using the term protest might be 
equated with taxpayers offering frivolous arguments. The act prohibited 
IRS from using this or any similar designation.[Footnote 18] 

In Cases Where Taxpayers Raised the Same Arguments in Appeals as in 
Collection, Appeals Agreed with Collection the Majority of the Time: 

Nearly 90 percent of taxpayers raised the same argument permitted by 
the Restructuring Act with both Collection and Appeals. IRS encourages 
taxpayers to discuss the issues they want to appeal with Collection 
because the matter may be resolved without the need for Appeals' 
involvement. As shown in table 2, Appeals agreed with Collection that a 
taxpayer's argument lacked merit in more than an estimated 80 percent 
of the cases where taxpayers raised the same argument in both 
Collection and Appeals. For example, taxpayers argued that they 
qualified for collection alternatives but were not in compliance with 
requirements for filing tax returns for prior periods, paying taxes for 
certain periods, or both.

Notes: The arguments do not sum to 100 percent because some taxpayers 
raised more than one argument permitted by the Restructuring Act. In 
addition, the percentage of cases where Appeals reached the same 
conclusion as Collection for all arguments permitted by the 
Restructuring Act is lower than the percentages for individual argument 
categories as it includes innocent spouse category data. This category 
had a lower percentage of cases where Appeals agreed with Collection on 
the merits of the argument. 

[A] We are 95 percent confident that the true value would be between 77 
percent and 95 percent. 

[B] We are 95 percent confident that the true value would be between 80

[End of table] 

More than half of the taxpayers that requested an IA (about 61 
percent)[Footnote 19] or OIC (about 56 percent)[Footnote 20] in Appeals 
were not compliant for tax periods in addition to the period under CDP 
review. Appeals officials added that when a taxpayer requests an OIC in 
Appeals, Appeals staff often spend a lot of time developing the case by 
requesting and reviewing documentation needed to determine the 
taxpayer's compliance and eligibility. Our review of the case files for 
the estimated 31 percent of taxpayers that asked both Collection and 
Appeals for an OIC indicated that Appeals staff spend time building 
cases. Appeals requested the OIC form from an estimated 33 
percent[Footnote 21] of these taxpayers, and an estimated 24 
percent[Footnote 22] provided the form. Appeals also requested 
supporting financial documents from an estimated 37 percent[Footnote 
23] of these taxpayers, and an estimated 24 percent[Footnote 24] of 
taxpayers that requested an OIC in both Collection and Appeals provided 
the requested information. IRS voiced concerns that many taxpayers are 
raising the same issues with Appeals that were rejected by Collection 
in what appeared to be efforts to delay collection of the liabilities. 

In an approximately 19 percent of the cases where taxpayers raised 
arguments permitted by the Restructuring Act, Appeals reached a 
different conclusion than Collection on the merits of the taxpayer's 
argument, but may have upheld the lien filing or levy. For example, in 
one case Appeals approved an IA rejected by Collection but upheld the 
lien to protect the government's interests in case the taxpayer 
defaulted. Appeals differed from Collection on the merits of the 
taxpayer's arguments for a variety of reasons, including a change in 
the taxpayer's circumstances or information. When Appeals differed from 
Collection on the merits of the taxpayer's argument, in an estimated 20 
percent[Footnote 25] of these cases the taxpayer provided different 
information to Appeals than to Collection. In addition, in an estimated 
11 percent[Footnote 26] of the cases when Appeals reached a different 
conclusion than Collection it was because the taxpayer did not provide 
requested information to Collection, but provided the information to 
Appeals. 

IRS Initiated Communication with CDP Taxpayers Multiple Times, 
Primarily by Telephone and Letter: 

After sending the lien or levy notice, IRS (Collection and Appeals) 
contacted the taxpayer multiple times using different methods. The 
range of communication between IRS and the taxpayers in our sample 
varied. For example, the maximum number of phone calls in a single case 
was 34 and the maximum number of letters was 17. The estimated median 
number of letters IRS sent to the taxpayers was 3.6 and the estimated 
median number of phone calls was 3.2.[Footnote 27] As shown in table 3, 
in general the median number of IRS-initiated contacts with taxpayers-
-letters, telephone conversations, and formal meetings--was twice as 
high as the median number of taxpayer-initiated contacts with IRS. 

Table 3: Estimated Median Number of Total and IRS-and Taxpayer- 
Initiated Contacts after Lien/Levy Notice Issuance for Cases Closed in 
Fiscal Year 2004:

Total contacts: 4.6; 
IRS-initiated contacts: 2.9; 
Taxpayer-initiated contacts: 1.2.

IRS-initiated contacts: 3.5; 
Taxpayer-initiated contacts: 1.5.

[End of table] 

After IRS sent the lien or levy notice, about 28 percent of taxpayers 
had at least one face-to-face contact, including meetings and drop-in 
visits, with Collection or Appeals. Most external stakeholders we 
interviewed stated that face-to-face CDP hearings were preferable, 
although a few representatives favored telephone conferences. Members 
of the National Association of Enrolled Agents, for example, said they 
preferred face-to-face meetings because they could review all documents 
and reach agreement in writing. In contrast, members of the American 
Institute of Certified Public Accountants stated that teleconferences 
were the most efficient way to handle CDP hearings. 

The September 2005 proposed changes to the CDP regulations describe 
specific circumstances under which Appeals will not offer a face-to- 
face conference to taxpayers or their representatives because it 
determines that a conference will not serve a useful purpose. Under the 
proposed changes, a face-to-face conference will not be granted if the 
taxpayer does not provide the required information in the written 
request for a CDP hearing or if the taxpayer proposes collection 
alternatives that would not be available to other taxpayers in similar 
circumstances. For example, because IRS does not consider OICs from 
taxpayers that have not filed required returns or made certain required 
deposits of tax, face-to-face conferences will not be offered to 
taxpayers that request an OIC but have not fulfilled those obligations. 
In addition, a face-to-face conference will not be held at the location 
closest to the taxpayer's residence or principal place of business if 
all Appeals officers or employees at that location are considered to 
have prior involvement with the taxpayer. 

The National Taxpayer Advocate (Advocate) and American Bar Association 
(ABA) expressed concern about the potential reduction in face-to-face 
hearings that may result from the proposed changes in the CDP 
regulations. The Advocate noted that certain taxpayers may need a face- 
to-face meeting with an Appeals officer who is familiar with local 
economic conditions, such as a business's payroll provider that went 
bankrupt. In our sample, an estimated 2 percent of taxpayers requested 
that Appeals transfer the CDP hearing to another location and Appeals 
accommodated all of these requests. However, we did not collect data on 
whether the relocation was to accommodate a face-to-face hearing. The 
Advocate also expressed concern that the centralization of Appeals 
activities to IRS campuses will result in only certain taxpayers 
receiving face-to-face hearings, such as those with representation. ABA 
representatives stated that the proposed regulations will grant Appeals 
more ability to deny face-to-face hearings, which would adversely 
affect pro se CDP taxpayers. They also said that Appeals cases can be 
more quickly resolved in person than through correspondence and phone 
hearings. 

Both Individuals and Businesses Used CDP, but Case Characteristics 
Varied: 

Individuals constituted the majority of taxpayers that requested a CDP 
appeal hearing, although business entities also exercised their right 
to request an appeal hearing. When compared to individual taxpayers 
with income tax liabilities, businesses with employment taxes 
liabilities had more delinquent periods. The majority of individuals 
requesting a CDP appeal were lower-income taxpayers. 

Most Taxpayers That Requested CDP Appeal Were Individuals, although 
Businesses Also Used the Program: 

Individuals constituted about 87 percent of all taxpayers that 
exercised CDP appeal rights. Of these individuals, approximately 79 
percent filed a CDP appeal related to individual income tax liability. 
Business entities constituted the remaining 13 percent of all taxpayers 
that requested CDP appeals, with business-related liabilities such as 
employment and unemployment tax. See table 4 for more detail on the 
types of taxpayers requesting CDP appeal.

[A] Includes sole proprietors. A sole proprietor is an unincorporated 
business that is owned by one individual. Although the majority of sole 
proprietors had income liability issues in CDP, there were also a small 
number that had business-related liabilities. 

[B] Trust fund recovery penalties may be assessed against any person 
who is responsible for collecting and paying withheld income and 
employment taxes, or for paying collected excise taxes, and willfully 
fails to collect and pay them to IRS. 

[C] Includes corporations, S corporations, and a small number of other 
"flow-through" entities, such as partnerships and trusts, and cases 
where a taxpayer appealed the collection of multiple types of 
liabilities, such as a business appealing both an employment tax and 
excise tax liability. An S corporation is a flow-through entity that 
distributes net income--as well as losses--to shareholders who are 
subsequently required to report the net income or loss on their 
individual tax returns and to pay any applicable taxes. Although flow- 
through entities do not generally pay taxes on income, they may still 
incur other types of tax liabilities, such as employment or 
unemployment taxes. 

[End of table] 

Both the ACS and Field Collection areas of IRS generate lien and levy 
notices, which may lead to eventual CDP appeals. ACS issued the vast 
majority of notices related to individual cases, about 88 percent. Our 
sample data suggest that Field Collection issued the majority of 
notices related to business cases, about 78 percent. However, because 
of a small sample size we cannot conclude that this observed level of 
notice issuance is statistically different from the level of notices 
issued to individuals. IRS procedures specify that simpler cases are 
usually handled by ACS. Field Collection handles complex, high-risk, 
high-dollar, and certain other types of collection cases. 

Although taxpayers are afforded CDP appeal rights for lien and levy 
notices, about 64 percent of all CDP appeals resulted from a levy 
notice. ACS issued levy notices for an estimated 49 percent of all 
cases, while Field Collection issued levy notices for about 15 percent 
of all CDP cases. Lien notices, which may be issued by either ACS or 
Field Collection, accounted for about 29 percent of all cases. For the 
remaining estimated 7 percent of cases, taxpayers either received both 
a lien and levy notice on the same liability amount and tax 
periods[Footnote 28] or a different type of levy notice, such as SITLP 
or FPLP. 

Businesses with Employment Tax Liabilities Had More Delinquent Periods 
Than Individuals with Income Tax Liabilities: 

Business entities that appealed proposed collection of quarterly 
employment tax liabilities had on average over twice as many delinquent 
periods included in their appeals as individual taxpayers with income 
tax liabilities.[Footnote 29] As shown in table 5, these businesses had 
on average nearly 6 delinquent periods included in their appeals. In 
calendar terms, this means that on average businesses that requested a 
CDP appeal for failure to pay employment tax liabilities were 
delinquent for nearly 1-½ years. The number of delinquent periods 
included in the CDP appeal for these taxpayers ranged from a low of 1 
to a high of 26 quarters, or in calendar terms, from 3 months to 6-½ 
years. In contrast, individuals who appealed the lien filing or levy on 
income tax liabilities in CDP had on average 2.6 delinquent periods, or 
years, included in their appeals. For individual income tax liabilities 
the number of multiple periods involved ranged from a low of 1 to as 
many as 9 years per case. 

Table 5: Average and Range of Number of Delinquent Tax Periods by Type 
of Tax Liability: 

Type of tax liability: Employment (quarterly); 
Number of delinquent tax periods: Estimated average: 5.7[A]; 
Number of delinquent tax periods: Range: Minimum: 1;

[End of table] 

Similarly, the estimated amount of the tax liability associated with 
CDP appeals varied widely and was associated with the type of tax 
liability involved. The highest median tax liability was associated 
with trust fund recovery penalty cases, followed by employment tax 
liabilities, as shown in table 6. 

Table 6: Estimated Median of Total Liability by Type of Tax Liability 
in CDP for Cases Closed in Fiscal Year 2004: 

Type of tax liability: Trust fund recovery penalty; 
Total median liability (dollars): $44,941. 

Type of tax liability: Employment; 
Total median liability (dollars): 30,403[A].

[B] The relative standard error for this estimate is 46 percent. 

[End of table] 

In general, taxpayers represented themselves more than half of the time 
in CDP appeal cases, an estimated 56 percent of the time. Individual 
taxpayers represented themselves even more frequently, about 61 percent 
of the time. Individuals engaged the services of a professional 
representative, such as a tax attorney, certified public accountant 
(CPA), or enrolled agent,[Footnote 30] during CDP about 30 percent of 
the time. Our sample data suggest that 50 percent of businesses 
retained professional representation; however, because of our small 
sample size we cannot conclude that this observed level of 
representation is statistically different from the level of 
professional representation for individuals. 

Most Individuals Were Lower-Income Taxpayers with Varied Liability 
Amounts: 

More than an estimated 50 percent of individual taxpayers who requested 
a CDP appeal had most recently reported an adjusted gross income 
(AGI)[Footnote 31] of less than or equal to $50,000 prior to their CDP 
appeals. The estimated median tax liability associated with these cases 
varied somewhat when compared to income level, as shown in table 7. 

Table 7: Estimated Adjusted Gross Income Level versus Median Tax 
Liability for Individual Taxpayers Requesting CDP Appeal for Cases 
Closed in Fiscal Year 2004: 

Adjusted gross income level (dollars): Zero or negative (under $1); 
Percentage of taxpayers requesting CDP[A]: 3; 
Median tax liability (dollars): 44,941[B]. 

Adjusted gross income level (dollars): $1 to $25,000;

Appeals Devoted Many Staff Hours to Resolving CDP Cases That May Not Be 
Consistent with Goals of the Program or an Efficient Use of Resources: 

The results of our case file review and interviews with IRS officials 
have raised concerns that certain types of taxpayers have used CDP in a 
manner that may be inconsistent with the goal of the Restructuring Act 
to ensure due process. IRS also raised concerns that taxpayers have 
used CDP in a manner that resulted in an inefficient use of Appeals' 
resources. Our case file review enabled us to develop quantitative 
estimates of the extent to which cases with selected characteristics of 
concern were present among cases closed by Appeals during fiscal year 
2004. IRS devotes a significant amount of its resources to resolving 
CDP appeals cases. Changing the CDP process could release a significant 
amount of Appeals' resources for other purposes. In operating the CDP 
program, IRS must balance efficient resource utilization against the 
goal of protecting taxpayer rights. 

Concerns about Certain Types of CDP Cases: 

The Restructuring Act permits any taxpayer who receives a lien or levy 
notice to request a CDP appeal hearing. The act makes no distinction 
with respect to the type of taxpayer, type of tax liability, or whether 
the liability is self-reported or asserted by IRS. According to the 
legislative history, the Senate Committee on Finance believed that 
following procedures designed to afford taxpayers due process in 
collections would increase fairness to taxpayers. However, the results 
of our case file review and interviews with IRS officials raised 
concerns that certain taxpayers are using CDP in ways that may be 
inconsistent with the goal of the Restructuring Act to ensure due 
process. These would include the following: 

Frivolous arguments: As discussed earlier, an estimated 5 percent of 
taxpayers requesting a CDP appeal presented a frivolous argument to 
either Collection or Appeals. An estimated 4 percent of CDP taxpayers 
raised a frivolous argument to Appeals alone. IRS has publicized those 
arguments that are considered frivolous and that will not be considered 
as a basis for contesting tax liabilities. IRS officials said that 
taxpayers that submit frivolous arguments may simply be delaying 
collection efforts. In the budget submissions for fiscal years 2005 to 
2007, the administration submitted a legislative proposal that would 
increase the penalty for filing frivolous income tax returns from $500 
to $5,000. The proposal would permit IRS to dismiss requests for CDP 
hearings (as well as IAs and OICs) if they are based on frivolous 
arguments or are intended to delay or impede tax administration. In 
2005, IRS's Office of Chief Counsel also issued guidance encouraging 
Counsel staff to coordinate with Collection staff in order to file a 
motion to levy during CDP proceedings where a taxpayer raises solely 
frivolous arguments. 

Nonresponsive taxpayers: About an estimated 20 percent of taxpayers 
requesting a CDP hearing in fiscal year 2004 did not respond at all or 
responded initially and then became nonresponsive to attempts by 
Appeals to contact them for additional information.[Footnote 32] IRS 
officials questioned whether taxpayers that requested CDP hearings but 
did not respond to Appeals' efforts to contact them were serious about 
resolving a lien or levy. According to Appeals' procedures, taxpayers 
are provided at least two opportunities by correspondence to schedule 
the CDP hearing or discuss the case. While it is possible that 
nonresponsive taxpayers may no longer reside at the most recent address 
on file with IRS, Appeals makes efforts to contact the taxpayers using 
the most recent information it has available. In addition, the taxpayer 
can initiate contact with IRS to inform it of a new address and 
continue the CDP hearing. If the taxpayer does not respond, Appeals 
will issue a final determination on the lien or levy. For cases closed 
during fiscal year 2004, nonresponsive taxpayers that requested a CDP 
hearing experienced an estimated average cycle time of 314 calendar 
days[Footnote 33] from the time they requested a CDP hearing until the 
time the final determination was issued by Appeals. As previously 
discussed, IRS generally suspends all collection efforts during CDP 
until the final determination is issued. 

Basis for questioning the existence of the liability: As discussed 
earlier, taxpayers challenged the existence or amount of the liability 
with both Collection and Appeals about 37 percent of the time. An 
estimated 38 percent of taxpayers raised the issue with Appeals alone. 
In addition, Appeals agreed with Collection's evaluation of the merits 
of the argument an estimated 89 percent of the time. However, as 
discussed earlier, in only 7 of 80 cases in our sample where the 
taxpayer raised the existence of the liability with Appeals during CDP 
was the taxpayer claiming not to have received a statutory notice of 
deficiency from IRS.[Footnote 34] The remaining 73 out of the 80 
taxpayers raised existence of the liability for a variety of other 
reasons, including contesting the amount of the liability. IRS intends 
to clarify the circumstances under which a taxpayer may appropriately 
dispute the existence or amount of the liability in CDP when it revises 
the hearing request form. 

Self-reported liabilities: Taxpayers that self-reported their 
liabilities accounted for nearly an estimated 50 percent of Appeals' 
total CDP caseload for cases closed during fiscal year 2004.[Footnote 
35] Of these taxpayers, nearly one-quarter raised the existence of the 
liability issue during their CDP appeals.[Footnote 36] The 
Restructuring Act states that taxpayers can use the CDP process to 
appeal the underlying tax liability in limited circumstances. IRS 
initially interpreted the language as meaning an additional tax 
assessment by IRS, not a liability reported by the taxpayer on the 
return. In 2004, the U.S. Tax Court rejected this interpretation and 
concluded that the term underlying tax liability referred to self- 
assessed amounts as well as amounts assessed under deficiency 
procedures. The U.S. Tax Court held that petitioners generally could 
dispute their self-reported tax liability because they had not received 
a notice of deficiency and had no other opportunity to challenge the 
merits of the disputed tax liability.[Footnote 37] 

Employment and unemployment taxes: In previous reports GAO has 
discussed the unique problems associated with ensuring business 
taxpayers comply with their employment tax deposit 
requirements.[Footnote 38] IRS also expressed concern about business 
taxpayers who use CDP to appeal collection action for employment and 
unemployment taxes because many of them continue to incur additional 
liabilities by not filing subsequent returns or paying related taxes, 
often referred to as "pyramiding." As previously discussed, businesses 
that requested CDP appeal for employment taxes were on average 
delinquent for 6 quarterly periods, or behind on their payments for 1- 
½ years. For example, in one case the business requested a CDP appeal 
hearing to contest collection of employment taxes dating back over 26 
quarterly periods, or 6-½ years. The administration has submitted a 
legislative proposal with its fiscal year 2007 budget to amend CDP 
procedures for employment tax liabilities. In contrast to most other 
CDP cases, the proposal would allow IRS to levy businesses with 
delinquent employment tax liabilities first, and then provide the 
taxpayer with the opportunity for a postlevy CDP appeal hearing within 
a reasonable period of time. This proposal is similar to the postlevy 
hearing established by the Restructuring Act for levies issued to 
collect a federal tax liability from state tax refunds under SITLP and 
for levies where IRS has made a finding that the collection of tax is 
in jeopardy. 

IRS also raised concerns that other types of cases result in an 
inefficient use of Appeals' resources. These include the following: 

Offers-in-compromise: In 2001, IRS established two centralized OIC 
processing centers to reduce inventory, processing times, and costs. 
IRS officials said that some taxpayers fail to work with these 
specialized units and instead go directly to Appeals to seek OICs. In 
addition, when making its determination about the acceptability of an 
OIC, Appeals in most cases does not refer the OIC to the specialized 
processing units or a Field Collection offer specialist for 
investigation or for a recommendation on acceptance or rejection. In 
contrast, Appeals refers CDP cases involving innocent spouse issues to 
either IRS's Centralized Innocent Spouse Operation (CISO) or a field 
examination office for investigation and evaluation. Appeals will delay 
its ruling on any other issues or collection alternatives until the 
CISO or field examination area issues a preliminary determination on 
the innocent spouse issue. As a result of taxpayers that seek OICs 
directly from Appeals instead of working with the specialized 
processing centers, Appeals deviates from its mission of settling 
disputes between taxpayers and Collection and instead spends time doing 
original case-building work, such as trying to get taxpayers to file 
overdue returns for prior periods, an important eligibility criterion 
for OICs. 

IRS also said that many taxpayers who apply for a collection 
alternative do not (1) meet the basic requirement of having filed all 
necessary tax returns or (2) provide with their CDP requests the 
necessary supporting documentation or a completed OIC application for 
Appeals to consider, causing further delay and consuming more staff 
resources. As discussed earlier, for those taxpayers that asked both 
Collection and Appeals for an OIC, Appeals requested the OIC 
application form and other supporting financial documentation from 
about an estimated one-third of the taxpayers. 

One option for ensuring that taxpayers timely provide overdue tax 
returns, supporting financial information, or a completed OIC 
application with their requests for a collection alternative would be 
to require taxpayers to provide this information before IRS accepts the 
request for a CDP hearing. However, according to officials from IRS's 
Office of Chief Counsel, under the current statute IRS may not deny a 
taxpayer's request for a CDP hearing even if the taxpayer only wants a 
collection alternative and has not met basic filing compliance 
requirements.[Footnote 39] Similarly, IRS said that it also lacks 
authority to deny a request for a CDP hearing to taxpayers seeking an 
alternative that fail to submit the supporting financial information or 
OIC application form. IRS also stated that most taxpayers would be 
unable to provide this information within the 30 days they have to 
request a CDP hearing. 

Another option would be to require taxpayers to provide the information 
within a reasonable time following the request for the CDP hearing and 
for IRS to proceed to make a final determination at that time on the 
basis of whatever information the taxpayer had provided. This would be 
similar to IRS's current practice of proceeding to make a final 
determination when taxpayers have not been responsive to IRS's request 
for information. At the time we completed our review, however, IRS had 
not determined whether it could do this without a statutory change. 

Installment agreements: As with OIC cases, IRS also said that many 
taxpayers do not provide the necessary documentation for Appeals to 
even consider an IA with their CDP requests. Instead of concentrating 
on dispute resolution, Appeals officers instead must attempt to bring 
noncompliant taxpayers into filing compliance in order to meet the 
basic eligibility criteria for the alternative, and then develop the 
IAs, including requesting application forms and the necessary financial 
information from the taxpayers. 

Low liability cases: For cases closed during fiscal year 2004, about 3 
percent of the taxpayers, or approximately 1,100, requested a CDP 
hearing for liabilities totaling less than $500. One Appeals official 
stated that small liability cases may not be the most efficient use of 
Appeals' resources. However, establishing a dollar threshold would deny 
some taxpayers the right to appeal the lien filing or levy at the 
judicial level while taxpayers with perhaps slightly higher liabilities 
would retain that right. In addition, for some lower-income taxpayers, 
an improperly assessed liability of $500 may represent a significant 
amount of money. The median for the most recently reported AGI for 
taxpayers in our sample with a liability of less than $500 was 
estimated at approximately $36,000,[Footnote 40] with a range from as 
low as about $11,000 a year to a high of more than $200,000 a year. 

Changing the CDP Process Could Free Up a Significant Amount of Appeals' 
Resources: 

Restricting CDP appeals rights for certain kinds of taxpayers or 
implementing other processing changes, such as requiring taxpayers to 
submit documentation for collection alternatives following the CDP 
hearing request, could release a significant amount of Appeals' 
resources for other purposes. According to IRS records, in fiscal year 
2004, Appeals allocated more than 285,000 direct staff hours, or about 
23 percent of all direct case time charges, to resolve about 32,000 CDP 
cases. We estimate that this cost was approximately $8.2 million. 

Table 8 shows the resources devoted to selected types of CDP cases. 
However, the data on direct case time charges and salary costs for each 
type of CDP cases may overstate the potential resource savings of 
changing the CDP process. First, the table represents the resources 
devoted to cases that exhibited the specific characteristic, but other 
characteristics could also be present, so the categories are not 
mutually exclusive. A case with a self-reported liability may also be 
an employment/unemployment tax case, and the resources devoted to that 
case would be included in each category. As a result, the potential 
staff hour savings to be realized from excluding more than one category 
of cases from CDP cannot be estimated by totaling the salary costs 
associated with each category. For example, suppose taxpayers with self-
reported liabilities and employment/unemployment taxes were deemed 
ineligible for the CDP process. The table shows that Appeals devoted 
about 135,000 staff hours to cases with self-reported taxes and about 
34,000 hours to cases with employment/unemployment taxes. However, the 
total staff hours that would be released by deeming both categories 
ineligible would not be the sum of those two categories (169,000 staff 
hours) because some of employment/unemployment taxes are also self-
reported. The actual total would be less. Second, although we obtained 
the total direct time charges involved in resolving each case in our 
sample, we could not isolate the amount of direct time Appeals expended 
in requesting and obtaining documentation in order to develop 
collection alternatives. (For more detail on the confidence intervals 
associated with the estimated hours and salary costs shown in table 8, 
see app. I.)

IRS Has Taken Some Steps to Improve the CDP Program: 

IRS has taken some steps to improve the CDP program. IRS has drafted a 
revised CDP hearing request form in an effort to assist taxpayers in 
determining what types of collection alternatives are available. In 
addition, in 2005, IRS issued proposed revisions to the CDP program 
regulations intended to allow Appeals to effectively and fairly handle 
the cases of taxpayers that raise issues of substance. Included in 
these proposed changes is a provision stating that Appeals will not 
offer a face-to-face meeting with a taxpayer when Appeals staff 
determine that the conference would not serve a useful purpose, such as 
with a taxpayer that offers only frivolous arguments. Further, the 
proposed changes state that a face-to-face conference need not be 
granted if a taxpayer does not provide the reasons for disagreeing with 
the lien filing or levy on the written CDP request. As previously 
discussed, stakeholder groups, including the Advocate and the ABA, 
voiced concerns about whether Appeals would have the ability under the 
proposed revised regulations to deny face-to-face hearings to taxpayers 
in need of assistance and thereby adversely affect taxpayer rights. 

In issuing the proposed regulatory changes for the CDP program, IRS 
asserted as its goal to increase efficiency without compromising the 
quality and fairness of review. Appeals anticipates collecting detailed 
information on CDP case outcomes as a result of planned enhancements to 
its information management system. IRS guidance lays out a seven-step 
process for data collection and analysis, the last of which is that 
managers should use data to follow up and monitor the effectiveness of 
a course of action. However, we found that IRS has not clearly assigned 
responsibility for analyzing future CDP outcome data to assess whether 
the revised hearing request form or updated program regulations achieve 
their objectives or whether further corrective actions will be 
necessary. 

Conclusions: 

Providing taxpayers with the ability to appeal unfair lien filings or 
levies is an important consideration in ensuring IRS continues to 
respect taxpayer rights as it collects tax revenue. However, Appeals 
devotes a significant amount of resources to CDP cases and decision 
makers need to weigh the value of the existing program against the 
value of potentially redirecting those resources to serve other 
taxpayers better. 

The results of our case file review and interviews with IRS officials 
raised concerns about whether Appeals is devoting a large share of its 
resources to providing temporary relief from collection action to 
taxpayers that Congress may not have intended to benefit from the CDP 
process. The statute currently affords all taxpayers the protection of 
due process appeal, even those that raise frivolous arguments or that 
do not respond to Appeals after requesting a hearing and may not be 
serious about working with IRS. For those taxpayers, which collectively 
may represent as much as approximately 24 percent of the total CDP 
workload, the delay in collection activity until Appeals issues its 
final determination may be an incentive to request an appeal, even 
though penalties and interest continue to accrue during the time the 
case is with Appeals. Other types of CDP cases represent those that may 
involve an inefficient use of Appeals' resources, such as taxpayers 
that are seeking OICs or IAs but are not in compliance with basic tax 
return filing requirements. 

IRS has taken some steps that may improve CDP program operations. 
Appeals anticipates collecting more detailed CDP case outcome data as a 
result of planned enhancements to its information system. However, IRS 
has not established responsibility for analyzing future program outcome 
data to determine if these changes will be effective. Given the 
significant share of Appeals staff resources dedicated to resolving CDP 
cases, balancing the need to employ these resources efficiently versus 
the goal of protecting taxpayer rights as required by the Restructuring 
Act has been, and will likely continue to be, a challenge for IRS. 

Recommendations for Executive Action: 

We are making three recommendations to the Commissioner of Internal 
Revenue to ensure that Appeals uses its resources in line with its 
mission as well as more efficiently. Specifically, we recommend that 
the Commissioner: 

* determine--for taxpayers seeking only a collection alternative--a 
reasonable amount of additional time beyond the current 30-day period 
for requesting a CDP hearing for these taxpayers to submit the required 
supporting financial information necessary for Appeals to consider the 
alternative of choice, and if seeking an OIC, to submit the OIC 
application form; 

* instruct Appeals to transfer CDP cases where taxpayers seek an OIC as 
a collection alternative and raise no liability issues to IRS's 
specialized processing units for investigation and evaluation of OICs 
before consideration by Appeals; and: 

* establish responsibility for analyzing future CDP appeal case outcome 
data in order to determine whether revisions to the hearing request 
form and program regulations will result in meeting their objectives. 

Matters for Congressional Consideration: 

Since the Restructuring Act permits any taxpayer who receives a lien or 
levy notice to request a CDP hearing, Congress should consider amending 
the statute to remove eligibility for CDP appeal for selected 
categories of taxpayers or types of cases if it judges that they have 
characteristics that are inconsistent with the Restructuring Act's goal 
of ensuring due process. These categories may include self-reported tax 
liabilities, including employment and unemployment taxes, or other 
categories deemed inconsistent with the goal of the Restructuring Act 
provisions. In order to leverage IRS resources more efficiently, 
Congress should consider requiring taxpayers that seek collection 
alternatives, such as OICs or IAs, and that raise no other allowable 
issues to comply with the basic eligibility criteria, that is, file all 
required tax returns before Appeals reviews their cases. In addition, 
Congress should consider requiring taxpayers that raise only collection 
alternatives to submit the supporting financial information needed to 
consider the alternative of choice, and if seeking an OIC without 
raising any liability issues, to submit the OIC application form within 
a reasonable time following their CDP request. 

Agency Comments and Our Evaluation: 

The Commissioner of Internal Revenue provided written comments on a 
draft of this report in a September 20, 2006, letter, which is 
reprinted in appendix II. The Commissioner agreed that our findings 
would assist IRS in its effort to improve CDP program operations, and 
provided technical comments and clarifications that we have 
incorporated throughout this report where appropriate. 

With regard to our recommendation on transferring cases where taxpayers 
request OICs as a collection alternative to one of IRS's specialized 
processing units for consideration before Appeals considers the cases, 
IRS agreed that our recommendation merited consideration, although IRS 
concluded that additional study is needed to assess the advantages and 
disadvantages of such a change in order to achieve the proper balance 
between agency resource allocation and imposing unnecessary delays in 
processing OICs. IRS also agreed with our recommendation regarding 
establishing responsibility for evaluating CDP outcome data in order to 
determine if the changes to the hearing request form and proposed 
regulatory changes will achieve desired objectives. IRS expressed 
support for our matter for congressional consideration related to 
suggesting that Congress consider amending the statute to remove 
eligibility for CDP appeal for selected categories of taxpayers or 
types of cases, noting that IRS has submitted several legislative 
proposals in past years aimed at limiting taxpayer access to CDP. 

In our draft report we recommended that IRS require taxpayers seeking a 
collection alternative to submit supporting financial information with 
their requests for a CDP hearing in order to consider the alternative 
of choice. We also recommended that IRS require each taxpayer seeking 
an OIC that raises no liability issues to submit the OIC application 
form with the hearing request. IRS disagreed with both of these 
recommendations. While IRS agreed that having this information would be 
desirable to facilitate consideration of taxpayers' requests for 
collection alternatives, IRS believes that most taxpayers would be 
unable to provide this information within the 30-day period taxpayers 
are provided to request a CDP appeal hearing. Further, IRS stated that 
it does not currently have statutory authority to deny CDP hearings to 
taxpayers who fail to submit financial information forms or the OIC 
application form. IRS believes that congressional action would be 
required to enable it to impose these requirements on taxpayers. We 
incorporated this information into the body of our report. Given IRS's 
concerns, we revised our report to say that taxpayers should be given a 
reasonable amount of time after filing a CDP request to provide 
supporting financial information and OIC applications. If taxpayers do 
not provide the materials within that time, IRS would proceed to make a 
final determination on the basis of available information. Further, 
because at the time we completed our review IRS had not decided if this 
could be done without a statutory change, we made this a matter for 
congressional consideration. Finally, we also added a recommendation 
that IRS should determine what a reasonable amount of additional time 
would be for taxpayers to assemble and submit this information since 
IRS would be in a position to make this determination. 

As agreed with your offices, unless you publicly announce its contents 
earlier, we plan no further distribution of this report until 30 days 
after its date. At that time, we will send copies of this report to the 
Secretary of the Treasury, the Commissioner of Internal Revenue, and 
other interested parties. Copies will be made available to others upon 
request. This report will also be available at no charge on GAO's Web

Appendix I: Objectives, Scope, and Methodology: 

Our objectives were to provide information on (1) the extent to which 
the Internal Revenue Service's (IRS) Office of Appeals (Appeals) found 
the IRS Collection function (Collection) had made errors in processing 
liens and levies and how often Collection Due Process (CDP) case 
results changed after a taxpayer requested a CDP appeal hearing; (2) 
the nature of the arguments presented by taxpayers seeking relief from 
a lien filing or levy and the amount of communication between IRS and 
taxpayers; (3) the characteristics of the taxpayers that availed 
themselves of the CDP appeal process, such as the amount of their total 
liability; and (4) whether opportunities exist to improve the 
operations of the CDP program while protecting taxpayer rights. 

To develop information addressing our objectives, we interviewed 
stakeholder groups with an interest in CDP, both within and outside of 
IRS. Within IRS we interviewed officials in Appeals as well as from the 
Collection area of the compliance divisions where CDP appeal cases 
originate. We also interviewed officials in the Office of Chief Counsel 
and the Office of the National Taxpayer Advocate. Outside of IRS, we 
met with representatives from organizations whose members provide 
professional representation to taxpayers during CDP appeals, including 
the American Institute of Certified Public Accountants, the American 
Bar Association, and the National Association of Enrolled Agents. 

We reviewed the Appeals Centralized Database System (ACDS) to determine 
whether it contained sufficient case results information to address our 
objectives. In conjunction with another GAO study addressing the 
operations of IRS Appeals, we tested the reliability of the data in 
ACDS. Based on this assessment, we found that data in ACDS were not 
sufficiently reliable for our use.[Footnote 41] Therefore, we collected 
data through a random probability sample of CDP cases closed by Appeals 
during fiscal year 2004 using IRS case files. The sample of 208 cases 
was drawn from a population of 32,241 cases. Results from this sample 
are generalizable to all cases closed in the CDP program in fiscal year 
2004. 

For each of the cases in our sample, we requested the Appeals closed 
office file and reviewed the documentation in the files to determine 
case characteristics, such as the ultimate outcome of the CDP appeal 
process, including whether a case was "sustained" or "not sustained." 
We reviewed documents available in the file, including the taxpayer's 
Request for CDP Hearing, the Case Activity Record (documented notes on 
the case history recorded by the Appeals officer), and the Appeals Case 
Memorandum (a summary memorandum outlining the Appeals officer's 
findings at the conclusion of the hearing process). Based on the 
documents available, we determined the nature of the arguments raised 
by each taxpayer, including whether the taxpayer sought a collection 
alternative, such as an offer-in-compromise (OIC) or installment 
agreement (IA). 

Through our case file review we also determined whether Appeals 
identified any evidence of improper procedures or errors that occurred 
during the Collection phase of the case. Based on the Internal Revenue 
Service Restructuring and Reform Act of 1998, as part of each case 
determination, Appeals is legally required to verify that the 
requirements of any applicable law or administrative procedure have 
been met. Specifically, Appeals will verify that Collection met legal 
and procedural requirements by reviewing whether (1) an assessment was 
made in accordance with the Internal Revenue Code, which requires IRS 
to make inquiries, determinations, and assessments of taxes;[Footnote 
42] (2) a notice and demand for payment was issued to the 
taxpayer;[Footnote 43] and (3) the taxpayer had a balance due at the 
time the notice of lien or levy was issued. In addition to reviewing 
cases to determine if Appeals found any instances where Collection did 
not comply with these requirements, we also identified cases where all 
of these legal conditions may have been met, but Appeals identified 
some other type of procedural error or problem. We used this broader, 
more inclusive definition of improper procedures when compiling and 
reporting our results. 

We also requested access to the Collection administrative file 
associated with each of our sample CDP cases in order to assess what 
transpired between the taxpayer and IRS during the collection phase of 
the case prior to the CDP appeal. We sought access to these files so we 
could develop additional case characteristics, such as the nature of 
the arguments raised by the taxpayer with IRS Collection, as well as 
the extent to which the taxpayer and the IRS employee working the 
collection case actively initiated communication with each other to 
resolve the collection dispute. Of the 208 cases in our sample, 162 
originated from the Automated Collection System (ACS) area.[Footnote 
44] When documents were missing from the Collection administrative 
files for ACS cases, we supplemented the file information by reviewing 
the ACS history transcript for the case. The remaining 46 cases in our 
sample originated in the Field Collection area of IRS. IRS Field 
Collection officials were concerned that providing GAO with access to 
the complete case file for our sample cases would be burdensome and 
potentially disruptive in cases where collection enforcement was 
ongoing. In response to this concern, we agreed to consider using case 
history information stored in the Integrated Collection System 
(ICS).[Footnote 45] We tested the reliability of ACS and ICS history 
transcripts by comparing the information on issues raised and 
communication contacts documented in the collection administrative file 
to the information in ICS for a subsample of cases. We found that the 
information in both systems generally agreed with the administrative 
case file data and was therefore sufficient for our data-gathering 
purposes. While we relied on ACS transcripts as a supplement to the 
collection case file documentation, for CDP cases that originated in 
the Field Collection area, we relied exclusively on reviewing the 
detailed ICS case history transcript. 

To record the descriptive data obtained from case file review for our 
sample cases, we developed a detailed data collection instrument (DCI). 
We refined this DCI through extensive pretesting, and also shared an 
interim draft of the instrument with officials from both IRS Appeals 
and Office of Chief Counsel to ensure that it was technically accurate. 
To ensure that the data entered on the DCI conformed to GAO's data 
quality standards, each completed DCI was subject to secondary review 
by at least one other GAO analyst. Reviewers compared the data recorded 
on the DCI to the data in the case files to determine whether they 
concurred with the interpretation of the case files and the way the 
data were recorded on the DCI. When there were differing perspectives, 
the analysts met and reconciled them. 

We input the data recorded on the DCIs into a computer data collection 
program. To ensure the accuracy of the transcribed data, each 
electronic DCI entry was compared to its corresponding paper DCI by 
analysts other than those who electronically entered the data. If the 
reviewers found any errors, changes were made to the electronic 
entries, and the entries were reviewed again to ensure that all data 
were transcribed accurately. 

To tabulate and analyze the results of the compiled DCI information, we 
used a standardized statistical software package. All cross-tabulation 
analyses of case file characteristic data were based on computer 
programs that were reviewed by a second independent data analyst. 

Because we followed a probability procedure based on random selection, 
our sample is only one of a large number of samples that we might have 
drawn. Since each sample could have provided different estimates, we 
express our confidence in the precision of our particular sample's 
results as a 95 percent confidence interval, less than plus or minus 8 
percentage points unless otherwise noted. This is the interval that 
would contain the actual population value for 95 percent of the samples 
we could have drawn. In some instances, we report our sample estimates 
as medians. The median, or midpoint in a series of numbers, was 
selected in certain instances because the total number of observations 
for a given characteristic varied greatly across the population. To 
determine the reliability of median estimates, we calculated the 
relative standard error associated with each estimate by dividing the 
standard error of the median by the median and multiplied by 100 to get 
a percentage. All medians based upon the results of our sample have a 
relative standard error of less than 30 percent unless otherwise 
stated. In instances where our sample estimate included a fraction, we 
rounded the estimate up if the fraction was greater than or equal to 
0.50. 

To estimate the salary costs associated with selected types of CDP 
cases with specific characteristics shown in table 8, we estimated the 
total direct hourly time charges based on the sample cases that had the 
characteristic of interest. We multiplied direct hourly time charges by 
a weighted hourly salary rate that was based on Appeals data for time 
charged to working CDP cases during fiscal year 2004. Each of the 
figures for direct hours worked and salary costs, as well as the 
average number of additional case characteristics present for each 
category, have their own confidence intervals, which are shown in 
tables 9, 10, and 11.

Appendix II: Comments from the Internal Revenue Service: 

Commissioner: 
Department Of The Treasury: 
Internal Revenue Service: 
Washington, D.C. 20224: 

September 20, 2006: 

Mr. Michael Brostek: 
Director, Tax Issues Strategic Issues Team: 
United States Government Accountability Office: 
Washington, DC 20548: 

Dear Mr. Brostek: 

Thank you for the opportunity to review and comment on the draft 
Government Accountability Office (GAO) report entitled "Tax 
Administration: Little Evidence of Procedural Errors in Collection Due 
Process Appeal Cases, but Opportunities Exist to Improve the Program," 
(GAO-06-1060). The findings of the GAO will prove to be a valuable 
resource as we continue our efforts to improve the Collection Due 
Process (CDP) program. 

The report includes a recommendation that taxpayers seeking a 
collection alternative be required to submit financial information with 
the request for a CDP hearing, Similarly, it also recommends that 
taxpayers seeking an offer-in-compromise (OIC) be required to submit 
the application form with the hearing request. While we agree that it 
would be beneficial to secure this information early in the process, 
most taxpayers seeking a collection alternative would be unable to 
provide this information within the current 30-day period they are 
given under Internal Revenue Code §§ 6320 and 6330 to submit a request 
for a hearing. 

We are studying the draft report's recommendation to have Appeals 
transfer OIC cases to one of the centralized OIC processing units for 
investigation and evaluation prior to Appeals consideration. Now that 
section 7122 has been amended to provide that an OIC is deemed accepted 
if not rejected within 24 months of being submitted, we need to ensure 
that any shift in the handling of OICs submitted during CDP hearings 
does not result in unnecessary delay. 

We agree with the recommendation to establish responsibility for 
analyzing future CDP case outcomes to determine whether proposed 
revisions to the hearing request form and proposed changes to the CDP 
regulations will meet our objective of increasing efficiency without 
compromising the quality and fairness of review. We are still in the 
process of determining the office responsible for analyzing the 
effectiveness of these changes and expect the assignment to be made in 
the near future. 

Finally, the draft report recommends that Congress consider amending 
the CDP statutory provisions to remove eligibility for CDP appeal for 
selected categories of taxpayers or cases. As you know, the Department 
of the Treasury supports the enactment of certain legislative proposals 
designed to exclude or limit access of certain taxpayers to the CDP 
hearing process. 

More detailed comments on the draft report's recommendations are 
enclosed. If you have any questions, please contact me or Karen Ammons, 
Deputy Chief, Appeals at {202 435-5600. 

Sincerely, 

Signed by: 

Mark W. Everson: 

Enclosure: 

Our comments on the report's specific recommendations follow: 

Recommendations 1 and 2(a): Require taxpayers seeking a collection 
alternative to submit with their CDP request form the supporting 
financial information needed to consider the alternative of choice; and 
require taxpayers who are seeking an offer-in-compromise (OIC} and who 
have raised no liability issues to submit an OIC application form with 
their initial CDP request. 

While desirable, most taxpayers seeking a collection alternative would 
be unable to provide this information within the current 30-day period 
taxpayers are given under Internal Revenue Code §§ 6320 and 6330 to 
submit a request for a hearing. Also, there are limits on the authority 
of the IRS under those sections. Therefore, as discussed further below, 
we cannot agree with these recommendations. 

The IRS, including the Office of Appeals, requires, in most instances, 
the submission of financial information as a condition to its 
consideration of a collection alternative, such as an installment 
agreement or OIC. This information must be provided on a completed Form 
433-A, Collection Information Statement for Wage Earners and Self- 
Employed Individuals, or Form 433-B, Collection Information Statement 
for Businesses. Each of the Forms 433-A and B is six pages long with at 
least 39 individual questions (45 for Form 433-B) requiring detailed 
answers about the taxpayer's assets, liabilities and expenses. Each of 
the forms also requires the submission of documentation substantiating 
the assets and liabilities reported, such as financial account 
statements for the past three months and statements from secured 
lenders. If a taxpayer is seeking an OIC, a Form 656, Offer in 
Compromise (the OIC application form), must also be submitted.[Footnote 
46] The IRS must have the information required by these forms to 
determine the acceptability of the requested collection alternative. 

Our experience over the last seven years is that many taxpayers have 
difficulty providing the minimal information currently required by the 
regulations to be included in the CDP hearing request. Based on this 
experience, and because of the detailed information required by Forms 
433-A or B and 656, we do not believe taxpayers realistically will be 
able to submit these completed forms within the 30-day period for 
requesting a CDP hearing. 

There are also limits under sections 6320 and 6330 on the authority of 
the IRS to require through regulations that these forms be submitted as 
part of the CDP hearing request. The CDP regulations could be amended 
to impose this requirement but the regulations could not provide that 
the failure to provide this information would prevent the taxpayer from 
receiving a CDP hearing, even if the taxpayer is only seeking a 
collection alternative. Section 6330(c)(2)(A) gives taxpayers the 
unqualified right to submit collection alternatives, such as an 
installment agreement or OIC, during the CDP hearing. In addition, the 
CDP statutory provisions, as currently written, require Appeals to do 
more than consider a taxpayer's request for a collection alternative. 
Appeals must verify that all legal and administrative procedural 
requirements for the collection action have been satisfied and must 
balance the government's need for efficient tax collection with the 
taxpayer's legitimate concern that the collection action be no more 
intrusive than necessary. Similarly, the CDP regulations cannot be 
amended to require taxpayers seeking collection alternatives to file 
all required tax returns as a condition to receiving a CDP 
hearing.[Footnote 47] Congressional action would be required to permit 
the IRS to deny a CDP hearing to taxpayers who fail to submit Form 433-
A or B, and where applicable Form 656, or who fail to file all required 
tax returns. 

Recommendation 2(b): Authorize Appeals to transfer OIC cases to one of 
the Internal Revenue Service's two specialized Centralized Offer in 
Compromise (COIC) processing units for investigation and evaluation 
prior to consideration by Appeals. 

The IRS is concerned that complete adoption of this recommendation 
could delay Appeals in making a determination about the acceptability 
of OICs during CDP hearings. The prevention of such delays is now 
receiving renewed priority due to the newly-enacted amendment to 
section 7122, which provides that an OIC is deemed accepted if not 
rejected within 24 months of being submitted. For certain categories of 
cases, the investigation and evaluation of an OIC by a COIC processing 
unit or Collection Field function prior to Appeals consideration could 
reduce the delay in the ultimate determination by Appeals about the 
acceptability of an OIC.[Footnote 48] On the other hand, there are many 
cases in which referral of an OIC to a COIC processing unit or Field 
Collection for investigation and evaluation could lengthen the time it 
would take Appeals to make a determination. Appeals and Collection will 
continue to discuss this recommendation to determine how best to 
achieve the proper balance between effectively allocating Appeals' 
resources and preventing delay in making determinations about the 
acceptability of OICs. 

Recommendation 3: Establish responsibility for analyzing CDP appeal 
case outcome data in order to determine whether revisions to the 
hearing request form and program regulations will result in meeting 
with their stated objective. 

We agree with the third recommendation to establish responsibility for 
analyzing future CDP case outcomes to determine whether proposed 
revisions to the hearing request form, Form 12153, and proposed changes 
to the CDP regulations will meet our objective of increasing efficiency 
without compromising the quality and fairness of review.[Footnote 49] 
The IRS is still in the process of determining the office responsible 
for analyzing the effectiveness of these changes and expects the 
assignment to be made in the near future. 

The draft report also recommends that Congress consider amending the 
CDP statutory provisions to remove eligibility for CDP appeal for 
selected categories of taxpayers or cases. As you know, the Department 
of the Treasury supports the enactment of the following three 
legislative proposals designed to exclude or limit access of certain 
taxpayers to the CDP hearing process. 

First, Congress should enact legislation to curb frivolous submissions 
and filings made to impede or delay tax administration by increasing 
the fines for such actions and giving the IRS the authority to 
disregard such submissions and filings.[Footnote 50] Taxpayers who 
submit CDP hearing requests making only frivolous arguments or who are 
otherwise attempting to delay collection should be denied a hearing. 

Second, Congress should amend section 6330 to allow the IRS to levy on 
payments to Federal contractors without first issuing a notice of the 
right to a CDP hearing. Payments to Federal contractors would be 
treated in the same manner as state tax refunds, with the taxpayer 
having the right to a hearing after a levy is made.[Footnote 51] 
Currently, Federal contractor payments are part of the Federal Payment 
Levy Program {FPLP) and are subject to levy only after the contractor 
has been given an opportunity for CDP hearing. This pre-levy hearing 
right diminishes the effectiveness of the FPLP with respect to those 
federal contractors who are able to receive payment before their 
challenge to the proposed levy action can be resolved. 

Third, Congress should amend section 6330 to permit levy to collect 
Federal employment tax liabilities prior to issuing a notice of the 
right to a hearing.[Footnote 52] Taxpayers owing employment tax 
liabilities would be offered a post-levy CDP proceeding, treating them 
in a manner similar to the current procedures applicable to levies 
issued to collect a State tax refund. Employment taxes represent nearly 
one-fifth of the IRS's total inventory of unpaid taxes. Frequently, an 
employer that fails to satisfy its payroll tax liability for one period 
will also fail to satisfy its ongoing employment tax liabilities for 
successive periods, resulting in a "pyramiding" of unpaid taxes. As 
your draft report emphasizes, pyramiding taxpayers make frequent use of 
the CDP hearing process. The existing framework for CDP procedures 
compounds the pyramiding problem by allowing these employers to 
continue operating without meeting their Federal employment tax 
obligations. For this reason, taxpayers with employment tax liabilities 
should be afforded post-levy hearing opportunities.

[2] The State Income Tax Levy Program (SITLP) matches a master file 
database of delinquent taxpayers eligible to be levied against a 
database of state tax refunds for each state participating in SITLP. 
The Federal Payment Levy Program interfaces with the Treasury Offset 
Program as a means for IRS to collect delinquent taxes by levying 
federal payments disbursed or administered through Treasury's Financial 
Management Service. 

[3] When taxpayers are unable to pay their tax liabilities in a single 
payment, IRS and taxpayers can enter into IAs that allow the taxpayers 
to pay their outstanding liabilities over time, generally through equal 
monthly payments. 

[4] When taxpayers are unable to fully pay their tax liabilities, they 
can request OICs from IRS to pay what they can afford. IRS writes off 
the rest of the liability. In 2005, IRS wrote off about $1 billion 
associated with OICs. See GAO, IRS Offers in Compromise: Performance 
Has Been Mixed; 
Better Management Information and Simplification Could Improve the 
Program, GAO-06-525 (Washington, D.C.: Apr. 20, 2006). 

[5] Collection is responsible for collecting unpaid tax liabilities 
from taxpayers that have balances due to IRS. 

[6] To measure the relative standard error associated with median 
values, we divided the standard error of the median by the median and 
multiplied by 100 to get a percentage. 

[7] Percentages cited in this paragraph indicate the portion of cases 
that exhibited each specific characteristic. However, cases could 
include multiple characteristics, so these categories are not mutually 
exclusive. As a result, the percentages do not add to 100 percent.

[9] A federal tax lien arises upon the taxpayer's failure to pay tax 
liabilities after a demand for payment and attaches to all of the 
taxpayer's property, I.R.C. § 6321. 

[10] Levies are issued under IRS's authority to seize delinquent 
taxpayers' assets, I.R.C. § 6331. 

[11] ACS is a computerized system that maintains balance due accounts 
and return delinquency investigations. With some exceptions, balance 
due accounts and return delinquency investigations are sent to ACS at 
the conclusion of normal collection notice routines. Examples of 
exceptions, which are available for assignment to the Field Collection 
area, include complex cases, "high-risk" cases, and high-dollar cases. 

[12] The Alaska PFD Program matches a master file database of 
delinquent taxpayers against a database of PFD applicants. PFD is 
provided to eligible Alaska residents and is the result of the state's 
oil wealth investment, which belongs to all residents of the state of 
Alaska. 

[13] A statutory notice of deficiency is IRS's determination of a 
taxpayer's income, estate, gift, or certain excise tax deficiencies 
sent to the taxpayer by certified or registered mail. The notice of 
deficiency consists of a letter explaining the purpose of the notice, 
the amount of the deficiency and the taxpayer's options, a waiver if 
the taxpayer should decide to agree to the additional tax liability, a 
statement showing how the deficiency was computed, and an explanation 
of the adjustments. A taxpayer that does not agree with the adjustments 
may file a petition with the U.S. Tax Court within 90 days of the 
notice date. 

[14] IRS can classify an account as Currently Not Collectible if the 
taxpayer cannot be located or contacted, payment would cause 
significant financial hardship to the taxpayer, the taxpayer is 
bankrupt, a business taxpayer no longer exists, or an individual 
taxpayer is deceased. 

[15] The Restructuring Act requires Appeals to verify that the 
requirements of any applicable law or administrative procedure have 
been met. In conjunction with this, Appeals will verify that an 
assessment was made in accordance with I.R.C. § 6201, that a notice and 
demand for payment was issued to the taxpayer in accordance with I.R.C. 
§ 6303, and that a balance due existed at the time the lien was filed 
or the CDP levy notice was issued. Appeals will also verify that other 
pre-lien/levy requirements were met. 

[16] IRS has published detailed guidance on 39 different types of 
frivolous arguments that IRS will not accept. This guidance includes a 
section specifically devoted to frivolous arguments prevalent in CDP 
cases. See "The Truth About Frivolous Arguments" available on IRS's 
Internet site, [Hyperlink, http://www.irs.gov/pub/irs-
utl/friv_tax.pdf]. 

[17] 70 Fed. Reg. 54681, September 16, 2005. 

[18] Prior to the Restructuring Act, taxpayers could be designated in 
the IRS master file and other records as illegal tax protesters when 
their tax returns or other correspondence with IRS contained certain 
specific indicators of noncompliance with the tax laws, such as the use 
of arguments that had been repeatedly rejected by the courts. 

[19] We are 95 percent confident that the true value would be between 
50 percent and 73 percent. 

[20] We are 95 percent confident that the true value would be between 
45 percent and 67 percent. 

[21] We are 95 percent confident that the true value would be between 
19 percent and 49 percent. 

[22] We are 95 percent confident that the true value would be between 
12 percent and 39 percent. 

[23] We are 95 percent confident that the true value would be between 
23 percent and 53 percent. 

[24] We are 95 percent confident that the true value would be between 
12 percent and 39 percent. 

[25] We are 95 percent confident that the true value would be between 6 
percent and 34 percent. 

[26] We are 95 percent confident that the true value would be between 3 
percent and 27 percent. 

[27] The median, the midpoint in a series of numbers, was selected to 
represent the typical amount of contact initiated by IRS, the taxpayer, 
or both, because the total amount of contacts varied greatly among 
taxpayers. All medians based upon the results of our sample have a 
relative standard error of less than 30 percent unless otherwise 
stated. 

[28] IRS may issue lien and levy notices simultaneously on the same 
liability amounts and tax periods to a taxpayer. 

[29] When issuing a lien or levy notice, IRS may include multiple 
delinquent tax periods in one notice. As a result, taxpayers may appeal 
the lien or levy on not just one but several delinquent periods. 
Individuals file returns and pay their income taxes on an annual basis, 
so the tax period is a calendar year. Businesses file returns and pay 
employment taxes on a quarterly basis, or a tax period of 3 months. 
Unemployment taxes are also paid on a quarterly basis unless the amount 
due is less than $500, in which case unemployment taxes may be paid 
annually. 

[30] Like attorneys and CPAs, an enrolled agent is an individual who 
has earned the privilege of practicing, or representing taxpayers, 
before IRS. To become an enrolled agent, a person must demonstrate 
technical expertise with tax matters by either passing a written 
examination or through past service and technical experience with IRS. 

[31] AGI is defined as the sum of total income less certain types of 
allowed expense deductions, such as moving expenses, alimony, or 
student loan interest expenses. Negative AGI indicates taxpayers whose 
reported deductions exceeded their total income. 

[32] This includes both taxpayers that were completely nonresponsive to 
all attempts at contact by Appeals as well as taxpayers that may have 
responded initially to Appeals, but in whose final case determination 
Appeals cited overall taxpayer nonresponsiveness as one of the deciding 
factors. 

[33] We are 95 percent confident the true value would be between 265 
and 363 days. 

[34] The seven cases are presented as descriptive information, not an 
inferential statistic. The sample size is not large enough to project 
this result. 

[35] We are 95 percent confident that the true value is between 40

[36] We are 95 percent confident that the true value is between 17 
percent and 35 percent.

Tax System with Little Consequence, GAO-04-95 (Washington, D.C.: Feb. 
12, 2004). See also GAO, Financial Management: Thousands of Civilian 
Agency Contractors Abuse the Federal Tax System with Little 
Consequence, GAO-05-637 (Washington, D.C.: June 16, 2005). 

[39] The Restructuring Act does not specifically address this issue. 
However, the statute as currently written permits taxpayers to submit 
collection alternatives, such as an IA or OIC, during the CDP hearing. 
In addition, Appeals is required to do more than consider a taxpayer's 
request for a collection alternative during the CDP hearing. Appeals 
must verify that all legal and administrative requirements have been 
satisfied and must balance the government's need for efficient tax 
collection with the taxpayer's legitimate concern that the collection 
action be no more intrusive than necessary. Therefore, IRS believes 
that where a taxpayer raises no other allowable arguments to the lien 
filing or levy except a collection alternative, IRS may not 
administratively require that taxpayer to comply with the same basic 
eligibility requirements that are imposed on non-CDP taxpayers before 
the case can be forwarded to Appeals for review of its acceptability. 

[40] The relative standard error for this estimate is 47 percent.

[44] ACS is a computerized system that maintains balance due accounts 
and return delinquency investigations. With some exceptions, balance 
due accounts and return delinquency investigations are issued to ACS at 
the conclusion of normal service center notice routines. Examples of 
exception cases, which are available for assignment to the Field 
Collection area, include complex, "high-risk," and high-dollar cases. 

[45] ICS is a computerized system that maintains balance due accounts 
and return delinquency investigations for cases that have been assigned 
to Field Collection. 

[46] Although Form 9465, Installment Agreement Request, is available 
for taxpayers to request payment of tax liabilities in installments, it 
is not required. 

[47] As you highlight in your draft report, the IRS will not consider a 
collection alternative unless a taxpayer has filed all returns required 
to be filed on or before the date the alternative is submitted. 

[48] For example, under current procedures, the Collection Field 
function assists Appeals in investigating and evaluating OICs in which 
the taxpayer's financial information is complex. 

[49] The proposed regulations have not become final and the revised 
form has not yet been issued.

Subcommittee on Investigations of the Senate Committee on Homeland
