Kansas Gas Tax

Kansas taxes gasoline at a flat 24.0¢ a gallon. The rate was last raised in 2003 and has not changed since; it is not indexed to inflation or fuel prices. Diesel is taxed at a slightly higher per-gallon rate. The EIA lists no local option fuel taxes for Kansas.

The rest of the state figure is two small charges: an environmental assurance fee of one cent a gallon, which funds cleanup of petroleum storage tank releases and was put back into effect on January 1, 2020 after a lapse, and a petroleum product inspection fee of a fraction of a cent. Because the excise has been fixed for more than two decades, its value has fallen with inflation.

Kansas’s total state tax of 25.0¢ a gallon is the 17th-lowest of the 50 states and D.C., against a 51-jurisdiction average of 33.8¢.

How the tax fits with fuel supply and price history is covered on the Kansas gas prices page.

Kansas’s state tax of 25.0¢ a gallon is lower than three of its four neighbors. Nebraska, to the north, charges 32.7¢; Colorado, to the west, 30.2¢; and Missouri, to the east, 30.0¢. Oklahoma, to the south, is the exception at 20.0¢.

The Missouri comparison has changed the most. Missouri raised its rate in annual steps from October 2021 to July 2025, which took it from below the Kansas rate to above it. The state line runs through the Kansas City metro area, so the two rates now meet inside a single urban market, with Kansas the cheaper side for state tax. Missouri is also the only one of the four that the EIA flags for local option fuel taxes, which its state figure does not include.

The Kansas figure splits into an excise of 24.0¢ and 1.0¢ in environmental and inspection fees. Adding the federal 18.4¢ gives a combined 43.4¢, of which the state’s part is a little under three-fifths. Against the average state tax of 33.8¢, Kansas is lower, ranking the 17th-lowest of the 50 states and D.C. Because none of these charges is indexed, the rank moves only when other states change their rates.

Oklahoma sits at 20.0¢ in the EIA's July 2026 table, and Kansas stands 5.0¢ above it. Every other bordering state is higher: Nebraska is at 32.7¢ (EIA table, July 2026), Colorado at 30.2¢ and Missouri at 30.0¢. Kansas is 7.7¢ below Nebraska, 5.1¢ below Colorado and 5.0¢ below Missouri, so the gap to Missouri and the gap to Oklahoma are both 5.0¢ in the EIA's July 2026 table.

Nebraska is the bordering state with the highest state total, and Oklahoma is the bordering state with the lowest. Kansas has 3 (EIA table, July 2026) of 4 bordering states above it, while 4 states border Kansas in all.

Across the 50 states and D.C., the EIA's July 2026 table puts Kansas at 25.0¢, the 17th-lowest. In that July 2026 table, 16 jurisdictions have a lower state total than Kansas, and 34 have a higher one. The range runs from 9.0¢ (EIA table, July 2026) (Alaska) to 73.6¢ (California), and the average is 33.8¢, which puts Kansas 8.7¢ below the average.

Of the 25.0¢ (EIA table, July 2026) Kansas total, 24.0¢ is excise, which is 96% of the state figure, and 1.0¢ is other state taxes and fees. The federal tax is 18.4¢ (EIA table, July 2026), and the combined total is 43.4¢, of which the state accounts for 58%. EIA lists state taxes of general application, so county and local taxes are outside these figures.
