Government Transportation Revenues and Expenditures:

Government Transportation Revenues

Government transportation revenues come from several sources, including user fees, transportation related taxes, and general revenues. This revenue funds government transportation expenditures on critical activities, like building highways, operating the Nation’s air traffic control system, and maintaining transit facilities.

2021 Year-in-Review (latest available)

  • In 2021 federal, state, and local revenues collected and dedicated to transportation programs totaled $382.5 billion (in 2021 dollars).
  • Federal transportation revenues accounted for over a quarter ($109.1 billion) of total transportation revenues collected in 2021. State and local government transportation revenues accounted for the remainder ($273.4 billion).
  • The Consolidated Appropriations Act (CRRSA Act) and American Rescue Plan Act (ARP Act) were passed in 2021 dedicating $45.0 and $58.4 billion to transportation respectively. For more information on COVID-19 transportation funds, visit COVID-19 Stimulus Funding for Transportation.
  • The Bipartisan Infrastructure Law (BIL) was signed into law in November 2021 and dedicated $673.8 billion to transportation between 2022 and 2025. For more information on BIL, visit Statistics on Transportation Funding in the Infrastructure Investment and Jobs Act.

The Bureau of Transportation Statistics' Government Transportation Financial Statistics (GTFS) aggregates data from a variety of sources to provide information on transportation-related revenues for all levels of government and for all modes of transportation. Data are also available for government transportation expenditures.

Total Government Transportation Revenues

For reporting, government transportation revenue is classified into two categories:
1.     Own-source revenue: taxes and charges levied on transportation-related activities and used specifically for transportation, for example motor fuel taxes.
2.     Supporting revenue: funds collected from non-transportation-related activities but dedicated to support transportation programs, e.g., receipts received by state and local governments from sales or property taxes. It excludes funds raised from transportation-related activities but used to finance programs other than transportation.  
Borrowing is not considered transportation revenue and is not included in the totals.
State and local government transportation revenue from all sources accounts for about three-quarters of total government transportation revenue. Federal transportation revenue from all sources accounts for the remaining quarter of total government transportation revenue.

Own-Source and Supporting Government Transportation Revenues by Level of Government

The following presents government transportation revenues collected, by mode, from taxes and charges levied on transportation activities (own-source revenue) and funds collected from non-transportation activities but dedicated to transportation (supporting revenue).
The FAST Act (Pub.L.No.114-94) was signed into law on December 4, 2015. One provision of that law was an immediate transfer of $51.9 billion from the General Fund to the Highway Account of the Highway Trust Fund. This transfer is shown in our Federal Supporting Revenue for 2016. For more information visit the FHWA Factsheet.  
The Infrastructure Investment and Jobs Act (also known as the Bipartisan Infrastructure Law or BIL) was passed on November 15, 2021. It dedicated $90.0 billion to the Highway Account of the Highway Trust Fund and $28.0 billion to the Mass Transit Account of the Highway Trust Fund. Those $118.0 billion in funds show up in the Highway Trust Fund in 2022.
