The first increase since 1987, in three steps
Mississippi’s gasoline tax stood at 18 cents a gallon from 1987 until 2025. House Bill 1, passed in the 2025 session as part of a plan to phase out the state income tax, raised it in three annual steps of 3 cents: to 21 cents on July 1, 2025, to 24 cents on July 1, 2026, and to 27 cents on July 1, 2027. Starting in 2029 the rate is to be adjusted each year for inflation, rounded to the nearest cent, with increases limited to 1 cent a year. The EIA’s current excise figure is 24.0¢.
Two other charges apply statewide: an environmental protection fee of 0.4 cents a gallon and an annual fee on each underground storage tank. The EIA flags Mississippi for local taxes. The main one is a 3-cent seawall tax on gasoline in the three coastal counties, Hancock, Harrison, and Jackson, which is not included in the state total.
The state total of 24.4¢ in the EIA’s July 2026 (revised August 2026) table is the 14th-lowest of the 50 states and D.C. The average across all 51 is 33.8¢. Mississippi pump prices are on the Mississippi gas prices page.

Of Mississippi's 24.4¢ (EIA table, July 2026), the excise tax is 24.0¢, which is 98% of the state total, and other state taxes and fees come to 0.4¢. With the 18.4¢ (EIA table, July 2026) federal tax added, the state's share of the combined state and federal total is 57%.
EIA lists state taxes of general application and excludes county and local taxes, so local option taxes on gasoline that apply in parts of Mississippi are not in these totals.
