IRS Releases FY 2015 Data Book

Posted by Ednaldo Silva

Statistics of Income (SOI) Tax Stats - IRS 2015 Data Book. The Internal Revenue Service (IRS) Data Book is published annually and contains statistical tables and organizational information on a fiscal year basis. The report provides data on collecting the tax revenue, issuing refunds, enforcing the law, and the budget and workforce. Undeflated business income tax is practically flat (trendless) since it dipped in 2009.

With a new online format, this year’s publication makes navigating data on taxpayer assistance, enforcement, and IRS operations easier, with graphic depictions of key areas and quick links to the underlying data. 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.
