What is the Missouri gas tax refund?
Missouri offers a refund on the state's motor fuel tax rate increases for drivers who paid for fuel at a Missouri station in a qualifying highway-use vehicle. The refund is claimed by filing Form 4923-H with the Missouri Department of Revenue, and it's based on how many eligible gallons you can document with receipts — no mileage log or Missouri residency required.
The catch is documentation. Your refund is only as good as the receipts backing it up, which is why most people either overestimate how much work it takes, or underestimate how much money they're leaving unclaimed.

How is my refund calculated?
Your refund is your total eligible gallons multiplied by the current refund rate per gallon. The calculator above estimates this from either your annual gallons or your annual miles and fuel economy.
When does the claim year start and end?
The purchase period runs July 1 through June 30. Fuel bought during that window counts toward that claim year, regardless of when you actually file.

The filing window opens July 1, right after the purchase period closes, and runs through September 30. Claims must be submitted to the Missouri DOR before that date.
Do I need to be a Missouri resident to claim it?
No. Eligibility is based on where the fuel was purchased, not your state of residence or where your vehicle is registered.
