Ten States With the Lowest Gas Tax in 2025

North Dakota

Gas tax total: 23 cents per gallon

North Dakota has one of the cheapest gas taxes in the country, but it’s the only state on this list to charge more than 22 cents per gallon. So, the Peace Garden State takes the tenth place for the lowest gas taxes.

Some good news for diesel vehicles, all special fuels are also priced at 23 cents per gallon. Emergency medical service vehicles may be eligible for a refund on the special fuel tax.

Delaware

Gas tax total: 23 cents per gallon

In Delaware, the excise tax rate on gasoline is 23 cents per gallon. However, folks who have special fuel vehicles and require diesel can expect to pay 22 cents per gallon.

You may want to hang around the Small Wonder State and do some shopping while you visit, since Delaware is one of the five states with no sales tax.

Louisiana

Gas tax total: 20.9 cents per gallon

Louisiana's excise tax on gasoline is just 20.9 cents per gallon. You can fill up your diesel-powered vehicle at the same tax rate of 20.9 cpg, too.

Things go downhill for convenience store purchases, though. Even though Louisiana has a low statewide sales tax rate of 4.45%, localities can charge an additional 7%, according to the Tax Foundation. That’s a lot of sales tax! And, if you want a lot of snacks, you could easily spend what you saved on gas.

In case you missed it: The Bayou State has a new income tax, as it implemented a single-rate individual income tax rate of 3% on January 1, 2025. Louisiana also enacted a higher $12,500 standard deduction, indexed to inflation. Other changes include setting a single, flat rate of 5.5% for its corporate income tax structure this year. The change eliminates the three-bracket system with rates that ranged from 3.5% to 7.5%, according to the Tax Foundation.

Texas

Gas tax total: 20 cents per gallon

Texas treats its residents well when it comes to income taxes. Of course, if you’re just passing through, being a state with no income tax doesn’t help you much. However, you can pay low taxes when you fill up your vehicle. At just $0.20 per gallon of gasoline and per gallon of diesel fuel, driving across the Lone Star State can feel less costly.

Oklahoma

Gas tax total: 20 cents per gallon

With a gasoline tax of $0.20 and a diesel fuel tax to match, stopping for gas in Oklahoma just makes sense.

Gas tax jumps $0.05 per gallon in Kansas, which has a gas tax of 25 cents per gallon. It might not seem like much, but those savings can add up. So, it's a good idea to fill up in Oklahoma if you're heading north.

Arizona

Gas tax total: 19 cents per gallon

Arizona has a cheaper excise tax on gas compared to Oklahoma, at only $0.19 per gallon. Diesel fuel is taxed at the same rate for some drivers. However, the rate jumps to $0.26 for heavy vehicles.

In case you missed it: While tax season is over, some Arizona taxpayers may have run into some confusion this year. If you received an Arizona family tax rebate last year, the IRS indicates that you must report that amount on your federal income tax return. According to the tax agency, rebate payments are classified as taxable income. For more details, see Your Arizona Family Rebate is Taxable: What to Know.

New Mexico

Gas tax total: 18.8 cents per gallon

Visiting New Mexico can offer a nice gas tax break. Though Mexico charges other fees and taxes, the total gas tax still comes in at under $0.20.

Diesel truck owners aren’t quite as lucky. The excise tax on diesel fuel is $0.21, and with the same $0.0188 in additional fees, the diesel tax totals 22.88 cents per gallon. Still, that is less expensive than most states in the country.

Hawaii

Gas tax total: 18.5 cents per gallon

Hawaii’s gas tax is nearly double Alaska’s, but it is still very reasonable at a mere 18.5 cents per gallon. The bad news is that this number does not include local tax options, so you could pay a higher rate. Additionally, it’s unlikely you will drive to Hawaii since the state is surrounded by the Pacific Ocean.

Hawaii also has one of the lowest sales tax rates in the U.S., but try to avoid grocery shopping in the state since groceries are taxable.

Mississippi

Gas tax total: 18.4 cents per gallon

If you can, stop for a fill up in Mississippi. Gas taxes are still below $0.20, and you can enjoy the same 18.4-cent per gallon tax rate on diesel fuel, too. Gas taxes become more expensive in the neighboring states of Tennessee and Alabama.

But Mississippi’s tax isn’t all good. You might want to avoid making too many purchases when you stop for gas. The state has a high sales tax rate, and Mississippi even taxes groceries at the full 7%.

What’s new this year: Mississippi is one of the states that implemented a major tax change this year. Effective January 1, the Magnolia State reduced the flat individual income tax rate to 4.4%, down from 4.7% in 2024. The rate will phase down to a flat 4% by January 1, 2026.

Alaska

Gas tax total: 8.95 cents per gallon

Alaska takes the win for states with the cheapest gas tax. At less than 8 cents per gallon, you can drive further with that $20 bill, and that’s a good thing since Alaska is the largest state in the U.S. Of course, no U.S. states border Alaska, so a road trip might be out of the question unless you fly there first.

If you do find yourself in Alaska, you can also enjoy no state sales tax. However, localities can charge their own sales tax, so don’t be surprised if your convenience store purchase costs a little more than expected.
