What is the alaska gas tax 2025 — 8.95¢/gallon?
In short
Alaska's state gas tax is 8.95¢ per gallon. A driver covering 15,000 miles a year at 28 MPG burns about 536 gallons and pays roughly $48/year in Alaska state gas tax — plus the 18.4¢/gal federal tax. Alaska's 8.95¢/gal rate is the lowest state gas tax in the nation (50th of 50) at about 8.95¢ — and it's a fixed rate that hasn't kept pace with inflation, so its real value has fallen for years.
This page shows Alaska's current state gas tax (8.95¢/gal) and works out how much state fuel tax you pay from your annual mileage and MPG. An 8¢/gal highway excise plus a 0.95¢/gal refined-fuel surcharge; marine fuel is taxed lower at 5¢. It excludes the 18.4¢/gal federal excise.

Worked example
The scenario
15,000 miles/year at 28 MPG in Alaska (8.95¢/gal).
The result
15,000 ÷ 28 = 536 gallons. State gas tax = 536 × $0.0895 = $48/year. With the federal 18.4¢ that's about $147 of fuel tax for the year.
