Federal budget formulation processes include fewer controls and reviews, and provide less information on tax expenditures—which represented an estimated $1.23 trillion in forgone revenues in fiscal year 2015—than for discretionary or mandatory spending. For example, in the President’s budget, tax expenditure revenue loss estimates are presented separately from related spending, making their...

The Earned Income Tax Credit (EITC), the Additional Child Tax Credit (ACTC), and the American Opportunity Tax Credit (AOTC) provide tax benefits to millions of taxpayers—many of whom are low-income—who are working, raising children, or pursuing higher education. These credits are refundable in that, in addition to offsetting tax liability, any excess credit over the tax liability is refunded t...

Internal Revenue Service (IRS) data are not sufficient for identifying who claims a tax expenditure and how much they claim for $492 billion or almost half the dollar value of all tax expenditures that GAO examined. Such basic data are not available at IRS for tax expenditures because they do not have their own line item on a tax form. This included $102 billion of tax expenditures that were not o...

GAO's previous work has shown that, once enacted, tax expenditures and their relative contributions toward achieving federal missions and goals are often less visible than spending programs, which are subject to more systematic review. One reason for this is that they often operate, in practice, like entitlement programs not subject to annual appropriations. Since 1994, GAO has recommended greater...

The tax credit for qualified research expenses provides significant subsidies to encourage business investment in research intended to foster innovation and promote long-term economic growth. Generally the credit provides a subsidy for research spending in excess of a base amount but concerns have been raised about its design and administrability. Government Accountability Office (GAO) was asked t...

How do taxpayers know if they will get a tax refund or owe money? Employers must withhold federal income taxes on employee pay, and employees can claim allowances to exclude part of their pay from such withholding. IRS publishes withholding tables so employers know how much to withhold. Recent tax law changes gave Treasury discretion to set the value of the withholding allowance for 2018. Treasu...

Among its findings: The federal government’s current fiscal path is unsustainable. Publicly held debt was 76 percent of GDP at the end of fiscal year 2017 and it will surpass its historical high of 106 percent within 14 to 22 years. ...

Eight of the 10 programs GAO reviewed reported using statist...

Fraudsters used false identities to steal at least $1.68 billion in tax refunds in 2016. To help address fraud and compliance issues, Congress moved up the deadline for employers to submit W-2s and had IRS hold refunds for those claiming certain tax credits beginning in 2017. These changes gave IRS more time to work on identifying discrepancies before issuing refunds. We found this process helpe...

The amount of money people spend on prescription drugs has nearly doubled since the1990s. Much of this increase is due to expensive brand-name drugs, but the prices of some generics have also gone up. We looked into changes in the drug industry and found that pharmaceutical and biotechnology sales revenue increased from $534 billion to $775 billion between 2006 and 2015. Additionally, 67% of drug...

Under the Affordable Care Act, people purchasing insurance through an exchange can re-enroll each year. If they don't select a plan, they're automatically re-enrolled in their existing plan or a similar one, if available. In 2016, 30% of re-enrollments were automatic. We examined whether automatic re-enrollment could have unintended financial consequences for consumers. We found that, from 2015 t...

According to GAO's analysis of data in the Census Bureau's Current Population Survey (CPS), on average, low-wage workers worked fewer hours per week, were more highly concentrated in a few industries and occupations, and had lower educational attainment than workers earning hourly wages above $16 in each year GAO reviewed—1995, 2000, 2005, 2010, 2015 and 2016. Their percentage of the U.S. workfo...

In its May 2016 report on the Low-Income Housing Tax Credit (LIHTC) program of the Internal Revenue Service (IRS), GAO found that state and local housing finance agencies (allocating agencies) implemented requirements for allocating credits, reviewing costs, and monitoring projects in varying ways. Moreover, some allocating agencies' day-to-day practices to administer LIHTCs also raised concerns....

Multiple federal programs may provide or support early learning or child care for children age 5 and under. Of these programs, GAO identified nine that describe early learning or child care as an explicit purpose. Fiscal year 2015 obligations for these nine programs totaled approximately $15 billion, with the vast majority of these funds concentrated in Head Start and the Child Care and Developmen...

In fiscal year 2016, the Department of Health and Human Services' (HHS) Centers for Medicare & Medicaid Services (CMS) assessed its advance premium tax credit (PTC) program as susceptible to significant improper payments. CMS instituted a qualitative method for assessing the susceptibility of its program that was consistent with requirements, including assessing each of the nine required qualitati...
