Federal Highway Trust Fund (HTF) Receipts

Most receipts from the Federal taxation of motor fuel, along with a number of other highway-related taxes, are deposited in the Federal Highway Trust Fund. The Trust Fund is made up of two accounts - highway and mass transit - and is dedicated for the funding of Federal surface transportation programs. In this way, taxes on highway users are used to fund highway facilities. The Trust Fund has provided a stable funding source for highway programs since it was established in 1956.

Motor-fuel tax receipts accounted for $14,317 billion in Fiscal Year 1994, or 85.9 percent of all Trust Fund tax receipts. Other taxes accounted for $2.350 billion. The balance in the Trust Fund earned interest income of $1.438 billion.

Federal Highway Trust Fund Balance and Commitments
The balance in the Highway Trust Fund grew from $9.581 billion at the end of Fiscal Year (FY) 1983 to $17.871 billion at the end of FY 1994. At the end of FY 1994, the Highway Account held a balance of $7.927 billion and had unpaid commitments of $42.623 billion. Funds for highway projects are committed when the project is initiated and are paid out as the project progresses. Because construction projects are long term in nature, the highway-user tax revenues can be committed to projects in advance of actual tax collection.
