Have a Sam's Club, Costco or Casey's Account? You've Been Saving Gas Receipts Without Knowing It

Open the app or sign in to your account, find your purchase history and scroll. Most people are surprised how far back it goes. One 14-gallon fill-up a week is about 730 gallons a year, or roughly $91 back from a single store. Two cars on the same membership and you're closing in on last year's average refund of $162.74.

Missouri received 17,119 refund claims in 2025, in a state with millions of drivers. The refund isn't hard to qualify for. The receipts are the problem, because nobody saves the paper ones. Your account already solved that.

The refund is claimed one vehicle at a time, and your purchase history doesn't know which car each fill-up went into. That's where FuelBack MO comes in. Add your screenshots, assign each fill-up to a vehicle, and see exactly what each one is worth before you file.

Only fill-ups at Missouri stations count, so anything across the state line has to come out. FuelBack MO reads the station's state on each receipt and flags the ones that aren't in Missouri, but it can miss one, and it's still on you to make sure every receipt you submit is accurate. Each entry should also show the date, the station, the gallons and the Missouri tax. If yours leaves something out, the Department of Revenue's refund team at motorfuelrefunds@dor.mo.gov or (573) 751-7671 can tell you whether it's enough.

Last year's window has closed, but every gallon you've bought since July 1, 2026 counts toward the claim you'll file next summer. Check your history now and add fill-ups as you go, and next summer's claim is mostly done before the window opens. For the rules on who qualifies, see the eligibility guide.
