1 Enforcement revenue collected in a fiscal year includes tax, interest, and penalties from multiple tax years. Some enforcement activities can take more than a year to close and may generate revenue over several years, so it is generally inappropriate to compare revenue collected in a given fiscal year to the staffing available for that same year.

2 Includes any revenue collection attributable to IRS Appeals activities.

3 Includes the Information Reporter Program (IRP) and the Automated Underreporter (AUR) Program.

4 Enforcement staffing levels presented in Full Time Equivalents (FTE).
