The N.C. Department of Transportation has an annual operating budget of over $4 billion. These monies come from three primary sources: the Highway Fund, the Highway Trust Fund, and federal funds. In addition to the three primary sources some receipts are collected for specified purposes.

The Highway Fund

The Highway Fund dates back to 1921, when the North Carolina General Assembly first imposed the gasoline tax of .01 cents per gallon on all motor vehicles fuels sold or distributed in the state. Revenue for the Highway Fund comes from a variety of sources, including the state gas tax, motor vehicle registration fees, title fees and federal-aid reimbursements. Traditionally, the Highway Fund supported highway construction and maintenance, the State Highway Patrol and the Division of Motor Vehicles. In the 1990s, the fund also began supporting public transportation and rail programs. With the passage of the Strategic Transportation Investments Bill this year, the fund will primarily support maintenance activities, including state aid to municipalities, and program operations.

The Highway Trust Fund

The Highway Trust Fund law was enacted in 1989 and identified specific highways that would be four-lane or improved in order to complete a 3,600-mile intrastate system. In addition, the 1989 law provided funding for urban loops around nine of our largest cities, including Asheville, Charlotte, Durham, Fayetteville, Greensboro, Greenville, Raleigh, Wilmington, and Winston-Salem. In 2013 the General Assembly passed HB 817, creating the Strategic Transportation Investments, establishing a strategic mobility formula for the prioritization of projects.

Federal Funds

Additional funds come from the Federal Government for federal-aid highway, transit, ferry, rail and airport projects. It should be noted that NCDOT must first expend its own state monies and is later reimbursed by the US Treasury. All federal funding is subject to annual Congressional Budget Appropriations, which in recent years have not been enacted by the start of the Federal Fiscal Year (FFY) which is October 1st. In the case of highway and transit funding, these funding levels are authorized by Congress in multi-year reauthorization bills. The current law is called Moving Ahead for Progress in the 21st Century (MAP-21) and is set to expire September 2014.

Other Receipts and Funding

The Triangle Expressway is NCTA’s first completed toll system.

Revenue Sources

State transportation revenues are derived from user fees in the form of Motor Fuel Tax (MFT), driver and vehicles fees collected by the NC Division of Motor Vehicles (DMV Fees) and a Highway Use Tax (HUT) on vehicle title transfers. Federal transportation revenues are derived from a federal MFT tax and vehicle fees (mostly on trucks). North Carolina's transportation funding comprises approximately 75 percent state revenues and 25 percent federal. The preceding pie charts illustrate the sources and uses of these funds.

Motor Fuel Tax — the state Motor Fuel Tax (MFT) is added to the cost of each gallon of gasoline and diesel sold in North Carolina. The state MFT rate, under state law, has a fixed portion and variable portion that is based on wholesale prices that can adjust every six months, on January 1st and July 1st. The N.C. Department of Revenue calculates and sets the state gas tax. For a historic look at state gas tax rates, visit http://www.dornc.com/taxes/motor/rates.html. The state MFT rate for the period of July 1st 2013 through June 30, 2013 was established by the NC General Assembly at 37.5 cents per gallon. The federal gas tax is 18.4 cents per gallon, and the federal diesel tax rate is 24.4 cents per gallon. These rates are established by the U.S. Congress and have not changed since 1993. Motorists pay these taxes at the gas pump.

DMV Fees — these fees are collected primarily from licensed drivers and vehicle registration. The various fees are set by the NC General Assembly, which was last updated in 2005. A listing of most fees can be found at: http://www.ncdot.gov/dmv/fees/.

Highway Use Tax — is a user tax based on the value of a vehicle at the time it is titled in North Carolina Revenue and the legislative tax rate of 3% which was not been changed since it was enacted in 1989 as part of the creation of the Highway Trust Fund (see below).

Funding Allocation and Distribution

Of the three revenue sources available for transportation funding these are allocated to the two state funds as follows:


Motor Fuel Tax
DMV Fees
Highway Use Tax
Highway Fund
75%
~90%
100%
Highway Trust Fund
25%
~10%
-

Highway Fund Distribution Formulas — the majority of the monies within this fund are distributed by formulas such as:

  • Maintenance (90% Mileage + 10% Population);
  • Contract Resurfacing (50% Needs + 37.5% Mileage + 12.5% Population);
  • Secondary Road Construction (County Mileage/Statewide Population);
  • Powell Bill (75% Population + 25% Mileage)

Highway Trust Fund — Strategic Mobility Formula

In 2013, G.S. 136-189.11 outlined the Strategic Mobility Formula (SMF) to allocate funding for Strategic Transportation Investments. SMF replaces the Equity Formula which was created in 1989 by the General Assembly which distributed funding 50 percent on the population of a region, 25 percent on the number of miles of intrastate highways left to complete in a region and the remaining 25 percent was distributed equally among the regions as programmed in the State Transportation Improvement Program.
