Tax Day 2024 Notes and Sources

March 26, 2024

National Priorities Project's Tax Day shows how your individual income taxes were spent. Those are a portion of the taxes withheld from your paycheck.

Tax Day materials do not include corporate taxes or the individual payroll taxes that directly fund Social Security and Medicare. To read more about where federal revenues come from, visit Where the Money Comes From.

Our Tax Day materials show how federal funds were spent during the corresponding fiscal year, the time period that most closely corresponds to the calendar year for which income taxes are due.

In order to do this analysis, we separate federal funds from trust funds. Trust funds, generated from sources such as payroll taxes, can only be used for specific programs like Social Security and Medicare. All other funds are federal funds, including revenue from your federal income taxes, and can be used for a wide variety of purposes.

We use analyzed federal fund “outlays” for for the fiscal year as reported by the White House Office of Management and Budget’s (OMB) and available from the Government Printing Office. These are the most recent available data for legally enacted federal spending at the time of publishing. In some cases, we use additional federal government data sources, noted below.

Tax Day Categories

When OMB publishes federal budget data, it uses several categories of spending called functions, and within those, subfunctions.

NPP uses 13 different budget categories to sort federal spending. These do not correspond exactly to the official government functions. Rather, they are meant to organize the many government subfunctions into more intuitive groupings. In order to create our Tax Day materials, federal fund outlays were sorted into the following categories:

Average Tax Bill

To generate average taxes paid for the U.S. and for each state, we used tax return data from the IRS. The most recent state data are for 2021. 

The averages are calculated by dividing income tax amount by the total number of applicable returns. The income tax amount represents total income taxes owed after deductions and credits but does not reflect refundable tax credits, such as the refundable portion of the EITC. The figure is then inflation-adjusted to 2023 dollars.
