Today National Taxpayer Advocate Nina E. Olson today released her 2015 Annual Report to Congress, expressing concern that the IRS may be on the verge of dramatically scaling back telephone and face-to-face service it has provided for decades to assist the nation’s 150 million individual taxpayers and 11 million business entities in complying with their tax obligations.

The report reiterates a recommendation the Advocate made in June that the IRS release its “Future State” plan documents, provide additional detail about their anticipated impact on taxpayer service operations, and solicit comments from the public. The report also recommends that Congress conduct oversight hearings on the plan.

The full report is available online.
