TREASURY OIG: Continued Inconsistent Use of Over-age Correspondence Lists Contributes to Taxpayer Burden and Unnecessary Interest Payments

Delays in processing taxpayers’ correspondence create a burden for taxpayers who must wait to obtain assistance and, in some cases, receive refunds. Over-aged correspondence has steadily increased from 40 percent in Fiscal Year 2012 to 49 percent in Fiscal Year 2015. The Treasury Inspector General for Tax Administration (TIGTA) found some managers continue to not adhere consistently to the required use of over-age reports, which contributes to the IRS’s inability to effectively reduce over-aged inventory.
