SOI Tax Stats - SOI Bulletin: Fall 2021 | Internal Revenue Service
The Statistics of Income (SOI) Bulletin is issued quarterly by the Statistics of Income Division of the Internal Revenue Service. The report provides the earliest published annual financial statistics obtained from the various types of tax and information returns filed, as well as information from periodic or special analytical studies of particular interest to students of the U.S. tax system, tax policymakers, and tax administrators. Selected historical and other data tables, previously published in the spring issue of the Bulletin are now only available on SOI’s pages of the IRS Website.
