Gas tax rates are set to increase in five states in the new year. Once they do, drivers in Florida, Georgia, Minnesota, New Jersey and Utah can expect to pay slightly more for each gallon of gas.
The increases in each state are small, ranging from less than 1 cent to 3.3 cents per gallon. But state taxes can add a chunk of change to the overall price of fuel. When the changes take effect on Jan. 1, the total state gas tax rates for those spots will be:
-
New Jersey: 45 cents per gallon.
-
Florida: 39.4 cents per gallon.
-
Utah: 39.2 cents per gallon.
-
Georgia: 33.9 cents per gallon.
-
Minnesota: 33.9 cents per gallon.
Meanwhile, there are a few states reducing their fuel taxes effective Jan. 1. New York and North Carolina make annual adjustments to their tax rates, and the calculations for 2025 will result in a smaller tax. The same is true in Vermont, where one fee is adjusted quarterly, and in Michigan, where the prepaid sales tax rate is revised monthly.
Understanding gas taxes
The price of oil and the cost of refining it are the biggest determining factors in the price of gas, which has averaged $3.02 per gallon so far in December. But federal, state and local taxes and fees can add significantly to the total.
On top of a federal tax of 18.4 cents per gallon, most states levy multiple taxes and fees on a gallon of gas. Those include some combination of excise taxes (imposed on goods, services and activities), sales taxes, environmental taxes and inspection fees.
Those costs add up to an average of 32.9 cents per gallon in state taxes, according to a NerdWallet analysis of U.S. Energy Information Administration data. Combined with the federal tax, that’s about 51.3 cents per gallon, on average, factored into the gas prices you see at your local station.
States with the highest gas tax
State tax rates vary widely. California’s rate (69.8 cents per gallon) and Illinois’s rate (67.1 cents) are highest, followed by Pennsylvania (58.7 cents). Alaska has, by far, the lowest state tax (9 cents per gallon), followed by Mississippi (18.4 cents) and Hawaii (18.5 cents).
State gas tax rate changes in 2025
In many cases, gas taxes are adjusted regularly based on the consumer price index, a proxy for inflation calculated by the U.S. Bureau of Labor Statistics. That means taxes may rise (or fall) with the annual rate of inflation. Sometimes states also phase in new or higher fees by increasing them incrementally.

States with falling tax rates
In Michigan, the monthly prepaid sales tax rate will decline for the fourth consecutive month, according to the Michigan Department of Treasury. For January, it will be 15.8 cents per gallon.

Combined with the state’s 30-cent excise tax on gas, as well as a 1-cent environmental protection fee, drivers pay 46.8 cents per gallon in state taxes and fees.
In New York, an annual adjustment to the state’s petroleum business tax will reduce the gas tax by eight-tenths of a cent, according to the New York Department of Taxation and Finance.
