Treasury Inspector General for Tax Administration (TIGTA) – Office of Disclosure Can Improve Compliance With the Freedom of Information Act Requirements, August 31, 2007: “The IRS improperly withheld information from requestors in 4 (4.6 percent) of the 88 FOIA and Privacy Act cases sampled. This represents a small improvement from the results in our Fiscal Year 2006 audit report (6.1 percent). Also, the IRS improperly withheld information from requestors in 12 (14.5 percent) of the 83 I.R.C. § 6103 cases. This represents a significant increase over the 2.3 percent error rate for I.R.C. § 6103 cases we reported last year. As a result, TIGTA estimates the Disclosure offices did not provide available tax records to 344 requests made under the FOIA and Privacy Act and to 815 requests made through I.R.C. § 6103. The errors appear to have occurred mainly because of inadequate research or simple oversight by the Disclosure office caseworkers.”
