The Internal Revenue Service (IRS) Data Book is published annually by the IRS and contains statistical tables and organizational information on a fiscal year basis. The report provides data on collecting the revenue, issuing refunds, enforcing the law, assisting the taxpayer, and the budget and workforce.

You can view selected summary graphs, key statistics, and descriptions of the tables and the IRS functions they cover. To download data tables on IRS and taxpayer statistics, visit the relevant section page listed on the left-side navigation column.

Graphic shows gross collections by type of tax for fiscal years 2012 through 2021. After several years of slow and steady growth in total gross collections, individual income taxes decreased slightly in fiscal year 2020, and then increased sharply in fiscal year 2021. Employment, estate and gift, and excise tax rose slightly over the ten-year time period. Business income taxes have decreased slightly from fiscal years 2015 through 2020, with a slight increase in fiscal year 2021.
