Online Collections

The Internal Revenue Service Statistics of Income Program began with the passing of the Revenue Act in 1916.  The purpose was to publish statistics related the operations of the internal revenue laws.

Between 1916 and 1953, the reports were of all aspects of income tax.  In 1954, the reports were split into categories- individual income tax returns, corporation income tax returns, estate income tax returns, and fiduciary income tax returns.  Beginning in the 1990s, the IRS has spreadsheets of some of the data from the reports.
