Compliance Presence


This section of the IRS Data Book highlights the IRS’s compliance efforts. Examinations (audits) of most types of tax returns, information reporting and verification, math error notices, and criminal investigations are critical tools for determining if income, expenses and credits are being accurately reported and to identify and resolve taxpayer errors and identify fraud. These tools ensure that IRS has a presence across all income and asset levels of taxpayers. While the IRS accepts most returns as filed, some are selected for examination using various methods, including random sampling and computerized screening. Most IRS examinations are conducted through the mail (correspondence) or face-to-face (field).

Graphic on the left shows the number of compliance activities completed during fiscal year 2022. The IRS completed nearly 18.5 million compliance activities, including sending almost 15.9 million math error notices. Graphic on the right shows the amount of recommended additional tax and assessments for fiscal year 2022, totaling $41.8 billion. Field exams accounted for $21.9 billion of this total.
