Missouri Gas Tax
Missouri’s state taxes and fees on gasoline total 30.0¢ a gallon, the 22nd-lowest of 51; with the 18.4¢ federal tax, drivers pay 48.4¢ a gallon in combined tax. Rates are from U.S. Energy Information Administration data as of July 2026.
What makes up Missouri’s 48.4¢
| Missouri state excise tax | 29.5¢ |
|---|---|
| Other Missouri taxes & fees sales/use taxes, inspection and environmental fees | 0.5¢ |
| Total Missouri state tax | 30.0¢ |
| Federal excise + LUST fee 18.3¢ excise + 0.1¢ LUST, unchanged since 1993 | 18.4¢ |
| Combined state + federal | 48.4¢ |
Petroleum Inspection fee: $0.0450 per 50 gallons ($0.0009/gal); Transport Load Fee $32.00 per 8,000 gallons ($0.0040/gal).
A five-step increase, with refunds for drivers
Missouri’s gasoline tax was 17 cents a gallon until 2021. Senate Bill 262, passed that year, raised it by 2.5 cents each July 1 from 2021 through 2025. The last step, on July 1, 2025, brought it to 29.5 cents, which is where the law leaves it; the rate is not indexed. The EIA lists the current excise at 29.5¢.
The same law lets drivers claim a refund of the increase. Anyone who keeps receipts for gasoline bought for highway use can file with the Department of Revenue for the added tax paid during each July-to-June year, with claims due by September 30. Because the full 12.5-cent increase is now in effect, the refundable amount is 12.5 cents a gallon from the July 2025 year onward. Missouri also charges a petroleum inspection fee and a transport load fee, together about half a cent a gallon.
The EIA flags Missouri for local option taxes. The state total of 30.0¢ in the July 2026 (revised August 2026) table is the 22nd-lowest of the 50 states and D.C. The 51-jurisdiction average is 33.8¢. For Missouri pump prices, see Missouri gas prices.

How Missouri Compares With Its Neighbors
Illinois has the highest state total among the 8 states that border Missouri, at 71.7¢ in the EIA's July 2026 table, and Missouri's 30.0¢ is 41.7¢ below Illinois. Nebraska lists 32.7¢ in that July 2026 table, and Missouri is 2.7¢ below Nebraska. Iowa lists 30.0¢ (EIA table, July 2026), identical to Missouri, so the gap is 0.0¢.
Tennessee lists 27.4¢ and Kentucky lists 26.4¢ in the EIA's July 2026 table. Missouri is 2.6¢ (EIA table, July 2026) above Tennessee, and Missouri is 3.6¢ above Kentucky. Kansas and Arkansas each list 25.0¢ (EIA table, July 2026), which leaves Missouri 5.0¢ above each. Oklahoma lists 20.0¢ (EIA table, July 2026), and Missouri is 10.0¢ above Oklahoma. Oklahoma's 20.0¢ (EIA table, July 2026) and Illinois's 71.7¢ are the lowest and highest totals among the bordering states.
Within the 30.0¢ (EIA table, July 2026), the excise part is 98% of the state total, and other state taxes and fees come to 0.5¢. Set beside the 18.4¢ (EIA table, July 2026) federal tax, the state's part of the combined total is 62%. Local option taxes on gasoline apply in parts of Missouri, and they are not in the 30.0¢ shown in the EIA's July 2026 table, which lists state taxes of general application and excludes county and local taxes.
