How much is the gas tax in Arkansas?

Arkansas levies a state excise tax of about 24.7 cents per gallon on gasoline. Adding the 18.4-cent federal excise tax brings the total to roughly 43 cents per gallon paid at the pump on regular gasoline.

Is diesel taxed differently in Arkansas?

Yes. Arkansas taxes diesel at a higher state rate of about 28.5 cents per gallon, and the federal diesel excise is 24.4 cents per gallon. Combined, diesel carries roughly 53 cents per gallon in excise tax, more than gasoline.

Does this include sales tax on gasoline?

No. The figures here are per-gallon excise taxes, which are the main fuel taxes in Arkansas. Some states also apply general sales tax to fuel, but the dominant cost is the fixed cents-per-gallon excise this tool calculates.

How do I find my annual gas tax cost?

Switch the tool to mileage mode and enter your annual miles and your vehicle's fuel economy in MPG. It divides miles by MPG to get gallons burned per year, then multiplies by the combined per-gallon tax to show your yearly fuel-tax bill.

Are these rates exact?

They are close estimates based on current Arkansas and federal excise rates. State rates can be adjusted by the legislature and indexing, and additional small fees may apply. Confirm the live rate with the Arkansas DFA if you need an exact figure.

The Arkansas Gas Tax Calculator shows how much excise tax is baked into the fuel you buy in Arkansas. Most drivers never see it itemized, but every gallon carries a fixed Arkansas state excise (about 24.7 cents per gallon on gasoline) plus the federal excise of 18.4 cents per gallon. This tool lets you see the tax on a single fill-up, or your total annual fuel tax based on how far you drive and your fuel economy.

How it works

Fuel excise taxes are charged per gallon, not as a percentage of price, so they do not change when pump prices rise or fall. The combined rate is simply the state rate plus the federal rate:

Gasoline: ~24.7 cents (state) + 18.4 cents (federal) = ~43.1 cents per gallon
Diesel: ~28.5 cents (state) + 24.4 cents (federal) = ~52.9 cents per gallon

In tank mode, the tool multiplies your gallons by the combined rate. In mileage mode, it first converts miles to gallons using your MPG, then applies the same per-gallon rate:

gallons = miles_per_year / mpg
fuel_tax = gallons x (state_rate + federal_rate)

Example and notes

A 15-gallon fill-up of gasoline carries about $6.47 in combined excise tax. Driving 12,000 miles a year in a 30-MPG car burns 400 gallons, so your annual gasoline tax is roughly $172. Diesel costs more per gallon in tax, so a diesel pickup at the same mileage pays noticeably more.

These excise taxes fund roads and bridges. They are separate from any general sales tax and from your vehicle registration fees. Rates can change, so confirm current figures with the Arkansas Department of Finance and Administration if you need precision.
