The Statistics of Income (SOI) program is managed by the Internal Revenue Service (IRS) and produces official statistical information derived from tax returns filed by individuals and businesses in the United States. SOI publishes detailed data on income, deductions, tax liabilities, credits, and distributions across income groups, industries, and geographic areas. Its products cover topics such as individual and corporate income tax statistics, estate and gift tax data, and patterns of income reporting.

The SOI portal provides access to tables, historical series, publications, and electronic datasets that are used by researchers, economists, policymakers, and analysts for economic and fiscal analysis, tax policy evaluation, distributional studies, and revenue forecasting. Because SOI statistics reflect actual tax filings, they are a key source for understanding income distribution and the tax system’s impact on economic and social outcomes.
