This interactive database provides IRS data on low-income federal individual income tax return filers. Use geographic filters to find and download data for specific ZIP codes, states, cities and towns, counties, metropolitan divisions, state legislative districts, and congressional districts. You can also access information on the characteristics of the population eligible for the EITC on a second page. These estimates come from the Urban Institute’s Analysis of Transfers, Taxes, and Income Security Model (ATTIS), using data from the 2015 American Community Survey (ACS).

The IRS dataset is limited to tax returns with a reported adjusted gross income of less than $60,000.
The estimates for the EITC-eligible population come from a simulation model. While they provide useful information about general economic, demographic, and workforce characteristics of the EITC-eligible population, they should not be used to determine EITC participation rates or error rates.
The Tax Policy Center distributes the reported ZIP code tax return data across other geographies using the Missouri Census Data Center's Geographic Correspondence Engine. For the methodology behind these calculations, please read the Tax Policy Center’s documentation report.
