New Jersey (AB 4011)


Changed its state gas tax formula to gradually increase taxes raised for fiscal years 2025-2029 to ensure the capital program is fully funded. Revenues collected from the state gas tax are allocated to the New Jersey Transportation Trust Fund to fund infrastructure projects. Under AB 4011, if revenue collected falls below or exceeds the annual highway fuel cap, the gas tax can be adjusted accordingly. New rates are to be determined by the state treasurer using the state’s gas tax formula. The new rates will take effect on Jan. 1 of every fiscal year.

Bills Summary

Virginia (SB 890)

Modifies fuel tax formulas (previously calculated on a percentage basis) to a fixed cents-per-gallon (CPG) rate that annually adjusts to changes in the Consumer Price Index (CPI). Increases gas and diesel fuel taxes over two years and indexes to annual changes in the CPI thereafter.

The gas tax increased from 16.2 CPG to 21.2 CPG on July 1, 2020, totaling 5 CPG in the first year. The gas tax will again increase from 21.2 CPG to 26.2 CPG and the diesel fuel tax will increase from 20.2 CPG to 27 CPG on July 1, 2021. The combined fuel tax increase totals 11.8 CPG in the second year and 16.8 CPG over two years. Both rates are indexed to annual changes in the CPI, effective July 1, 2022.

The additional tax imposed on the average wholesale price of a gallon of fuel is expanded throughout the commonwealth (paid by fuel distributors and previously only applied to retailers along Northern Virginia’s I-81). The fuel tax formula was also modified (also previously calculated on a percentage basis) to a fixed CPG rate that annually adjusts to changes in the CPI. Moreover, the rate was modified from 2.1% of the average “wholesale price” of a gallon of fuel to a fixed CPG rate of 7.6 CPG for gas and 7.7 CPG for diesel. Additionally, the 2.03% diesel fuel tax that would have become effective on July 1, 2021, was repealed.

District of Columbia (23-760)

The previous rate was 23.5 CPG and will increase to 28.8 CPG and again to 33.8 CPG by Oct. 1, 2021. This increase totals 10.3 CPG. Additionally, the rate will be adjusted annually based on the greater of the annual change in the CPI or zero thereafter. This will make D.C.’s motor fuel tax rate equal to the combined state and regional tax rate in Northern Virginia, which is currently 28.8 CPG for gas and will increase to 33.8 CPG by July 1, 2021. According to D.C.’s Office of the Chief Financial Officer, the gas tax is imposed on every importer of motor fuels, including gasoline, diesel fuel and combustible gases and liquids suitable for the generation of power for motor vehicles. All revenue from this tax is dedicated to the Highway Trust Fund.

Increased the state gas tax by 10.5 cents-per-gallon and the diesel tax by 19 cents-per-gallon. Ohio’s gas and diesel tax, currently at 28 cents a gallon, will go up to 38.5 cents and 47 cents, respectively.

Virginia SB 1716

Imposed a local 2.1 percent tax on the average wholesale price of fuel in districts along the I-81 corridor which raises gas prices by about 7 cents-per-gallon in those areas. The diesel tax will increase to 2.03% of the statewide average wholesale price per gallon, which would begin in July 2021. The revenue generated from the local gas tax and diesel tax will go toward the I-81 Improvement Fund, but other revenue will be distributed to other transportation projects.

2018 Legislative Action
Bills Summary

Missouri House Bill 1460

Increased the state motor fuel tax by 10 cents per gallon over four years and dedicated the new revenues to the cost of the state highway patrol. The bill also included tax rate increases for diesel and alternative fuels (natural gas, propane and others). The tax increases included in this bill are subject to voter approval per constitutional restrictions on state revenue collections. Voters did not approve the increases, see 2018 Voter Action for more information.

Oklahoma House Bill 1010

Increased the tax on gasoline by three cents per gallon and the tax on diesel by six cents per gallon. The revenues created by this increase are dedicated to the ROADS Fund which has a statutory cap on total revenues. Thus, this increase allows for an expedited path towards that total cap but effectively does not create an increase in transportation funding as other revenues will be moved out of the ROADS fund. See Oklahoma HB 1014 for additional information regarding the ROADS fund formulas.

Utah Senate Bill 276

Accelerates indexing provisions originally implemented in Utah House Bill 362 (2015, see below). The bill lowers the artificial price floor at which the indexing provisions kick-in and increases the percentage rate tax levied on that price floor. The immediate impact on the gas tax rate is neutral. However, this acceleration is likely to cause increased fuel tax rates in future years.

West Virginia Senate Bill 1006

West Virginia's motor fuel tax is a combination of a flat rate of 20.5 cents per gallon tax and a variable rate tax on the wholesale price of fuel. This bill increased artificial price floor of the 5 percent wholesale tax from $2.34 to $3.04, effectively increasing the variable-rate portion of the fuel tax by 3.5 from 11.7 cents to 15.2 cents per gallon.

Bills Summary

Maryland House Bill 1515

Among other provisions, this bill indexes motor fuel tax rates to the Consumer Price Index starting in FY 2014 and limits the increase to no more than 8 percent of the rate effective in the previous year. It also phases in a new sales and use tax equivalent rate on motor fuel (based on a percentage of the retail price), with the final rate contingent on whether federal legislation on out-of-state sales tax collection is enacted by Dec. 1, 2015. In addition, the legislation requires the Maryland Transit Administration (MTA) to index transit fares to inflation starting in FY 2015.

Massachusetts House Bill 3535

Pennsylvania House Bill 1060

Among other provisions, this comprehensive transportation funding package repeals the state’s cents-per-gallon fuel tax as of Jan. 1, 2014, and replaces it with an increased rate on the oil company franchise tax. This increased rate is achieved by raising and removing the cap on the average wholesale price of fuels subject to the tax. Beginning Jan. 1, 2017, the cap is eliminated and a $2.99 floor is put in place. The bill also raises various fees to the rate of inflation and indexes them to inflation thereafter; increases funding for multimodal and public transportation; and creates an optional county vehicle registration fee.

Vermont House Bill 510

This bill imposes a 4 percent tax on the average retail price of gasoline over two years (within limits) while also lowering the cents-per-gallon gas tax by a total of 6.9 cents per gallon. It is predicted to yield a net gas tax increase of 5.9 cents per gallon in FY 2014. The bill also raises the diesel tax by 3 cents per gallon over two years.

Virginia House Bill 2313

This legislation repeals Virginia’s cents-per-gallon gas tax entirely. In place of the previous 17.5 cents-per-gallon tax, the bill 1) establishes a percentage-of-wholesale-price tax of 3.5 percent for gasoline and 6 percent for diesel, with additional rate increases contingent on whether federal legislation on out-of-state sales tax collection is enacted by Jan. 1, 2015, 2) increases the dedicated share of existing general sales tax revenues used for transportation from 0.5 percent to 0.675 percent, and 3) also raises the sales tax itself by 0.3 percent across the state, with the additional revenues also to be allocated to transportation purposes. The bill further creates a $64 annual fee on hybrid, alternative fuel and electric vehicles. (The fee for hybrid vehicles was repealed in 2014.)

Wyoming House Bill 69

This bill raises the total tax on gasoline and diesel from 14 cents per gallon to 24 cents per gallon, effective July 1, 2013.
