The tables below detail the number of cases in both Appeals and Chief Counsel. Each table shows the number of prior year cases pending, received, closed, and cases pending as of the close of the fiscal year.
This table provides information on the workload of IRS's Appeals Office. The Appeals mission is to resolve tax controversies, without litigation, on a basis that is fair and impartial to both the taxpayer and the Government. The Appeals Office considers cases that involve examination, collection, and penalty issues. Taxpayers who disagree with the IRS findings in their cases may request an Appeals hearing. The local Appeals Office is separate and independent of the IRS office that proposed the tax adjustment, collection action, or penalty.

The internal security activities detail employee and non-employee violations by outcome, as well as various financial accomplishments.
Finally, on a yearly basis, the IRS publishes details of information returns received, number of contacts, and additional tax and interest assessed. These data can be found in the Information Reporting Program tables.
