This section of the IRS Data Book presents information on collections and penalties resulting from individuals’ or entities’ failure to comply with the tax code. Failure to comply with filing, reporting and payment requirements may result in civil penalties or, in some cases, criminal investigation. IRS’s Collection function collects Federal taxes that have been reported or assessed but not paid and secures tax returns that have not been filed. Additionally, this section presents data on the IRS Independent Office of Appeals workload. The mission of Appeals is to resolve tax controversies without litigation, on a basis that is fair and impartial to both the taxpayer and the Federal Government.

Graphic shows the amount of civil penalties assessed by the IRS in fiscal year 2023, a total of $65.6 billion. Over $44.4 billion was assessed on individual and estate and trust income tax returns; $5.9 billion was assessed on businesses.
