SOI Publications Archive

Here you'll find PDFs of SOI's historical publications. Beginning in 1916, Congress mandated the annual publication of statistics related to “the operation of the internal revenue laws.”

In 2009, SOI began digitizing nearly 500 print publications (and more than 50,000 pages) from its library. As a result of this effort, a wealth of historical tax data is now easily accessible in electronic format. The archive includes publications from 1916 through 1999. Publications for 2000 to present are available from the Tax Stats landing page here.

The oldest report available here was published in 1863. The Report of the Commissioner of Internal Revenue for 1863 contains information on the collection of revenue by source and district of collection. From 1863 to today, the Annual Report of the Commissioner of Internal Revenue, later called the IRS Data Book, presents an annual overview of IRS operations.

Early SOI publications, from 1916 to 1933, compiled all available tax information into one publication, the annual Statistics of Income Report. Beginning in 1934, SOI reported tax information for individuals and businesses separately, published as Parts 1 and 2 of the Statistics of Income Report, respectively. Beginning in the 1950s, these reports were replaced with annual and special reports, usually focused on single taxpayer groups.

In 1981, SOI introduced the SOI Bulletin, replacing many of its earlier reports with a quarterly publication that contains summary articles and tables on a wide range of tax topics.

All of the archive files are Adobe Acrobat PDFs. A free Adobe Acrobat reader is available for download, if needed.
