The United States Internal Revenue Service, which is responsible for collecting taxes and administering the Internal Revenue Code, collects and publishes historical data related to taxation across the 50 states.  This includes total tax revenue, total number of tax returns, number of people that pay income tax, total state income tax revenue, etc.

The most recent information regarding the total number of persons who filed individual income tax returns across the 50 states was taken from Table 3. Number of Returns and Other Forms Filed, by Type and State, Fiscal Year 2022 for this data series. For more information about this table see the IRS Data Book. The percentage of people in a state filing income tax returns was derived by dividing the number of people filing individual income tax returns by the total number of tax returns filed.
