GAO discussed the Internal Revenue Service's (IRS) request for fiscal year (FY) 1993 supplemental funds for the purchase of computer and telecommunications equipment. GAO noted that: (1) IRS proposed purchases represented accelerated acquisitions of planned computer purchases to support its tax systems modernization (TSM) program; (2) two of the projects, totalling $15.7 million, were short-term and, because of schedule delays, would become operational at the same time as the replacement TSM systems; (3) IRS requested $25.3 million for telecommunications modernization, but did not detail its TSM telecommunications requirements or make site-specific plans; (4) most of the remaining $107.4 million requested was to accelerate the replacement of obsolete equipment that was planned for FY 1994, which would greatly increase IRS capabilities and aid in TSM implementation; and (5) IRS expects to have approval of the acquisitions by June 1, 1993, and obligate the funds by the end of the fiscal year.
