Frequently asked questions
What is the Missouri gas tax refund rate for 2027?
Missouri currently pays back 12.5¢ per eligible gallon for claim year 2027. This is the state's official per-gallon refund rate — always double-check the current rate on Form 4923-H before filing.
When is the 2027 Missouri gas tax refund deadline?
The filing deadline for claim year 2027 is September 30, 2027. Claims must reach the Missouri Department of Revenue by that date.
Can I file a Missouri gas tax refund claim after the deadline?
No. Missouri doesn't accept late claims. If the September 30 deadline passes, fuel from that claim year can't be refunded, but fuel bought since July 1 counts toward the next claim.
Does the deadline change every year?
The structure doesn't change — purchases from July 1 through June 30 make up the claim year, and the filing window is July 1 through September 30 right after. Only the specific dates shift forward one year at a time.
