SOI Tax Stats - IRS Data Book

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 2008 through 2017. There has been slow and steady growth in total gross collections, which include individual income, business income, employment, estate and gift, and excise tax.

Highlights of this year's Data Book

  • During Fiscal Year (FY) 2017, the IRS collected more than $3.4 trillion, processed more than 245 million tax returns and other forms, and issued almost $437 billion in tax refunds.

  • In FY 2017, more than 55 million taxpayers were assisted by calling or visiting an IRS office.

  • The IRS continued a years-long effort to fight tax-related identity theft on many fronts, with another 524 criminal investigations completed.

  • Of the taxpayers who participated in the 2017 Comprehensive Taxpayer Attitude Survey (CTAS), 88 percent said it is not at all acceptable to cheat on their income taxes, and nearly all (95 percent) believe it is a civic duty to pay their fair share of taxes. Additionally, most taxpayers (79 percent) are satisfied with their personal interactions with IRS. See the 2017 CTAS report for more details.
