Who can get a Missouri gas tax refund and what it covers

Missouri's gas tax refund program is for farmers, commercial fishermen, and certain other businesses that buy gasoline or diesel fuel for off-road use. The state refunds the fuel tax you paid on purchases used for farming equipment, irrigation pumps, grain dryers, fishing boats, or other non-highway purposes. You cannot get a refund on fuel used in vehicles driven on public roads, even if you own a business.

The refund amount depends on how much fuel you bought for may have access to uses during the tax year. Missouri's fuel tax is currently 17.3 cents per gallon for gasoline and 17.3 cents per gallon for diesel. You claim the refund through the Missouri Department of Revenue, and the state processes it as a credit against your state income tax or issues a separate refund check.

To be may be able to access, you must have kept records of your fuel purchases—receipts, invoices, or fuel tank logs that show the date, amount, and type of fuel. The state will ask to see these records, so do not discard them after purchase.

Key Takeaways

  • Missouri refunds fuel tax only on gasoline and diesel used for farming, commercial fishing, or other off-road business purposes, not on fuel for highway vehicles.
  • You must keep receipts or invoices showing the date, amount, and type of fuel purchased to support your refund claim.
  • The refund is claimed on Form MO-1040 (individual income tax return) or through the Missouri Department of Revenue's fuel tax refund process for businesses without income tax liability.
  • The state processes refunds as a credit against your state income tax or as a separate check, typically within 30 to 60 days of approval.
  • You can file for the prior tax year only; you cannot claim a refund for fuel purchased more than one year ago.

How to file your fuel tax refund claim

If you file a Missouri state income tax return, you report the fuel tax refund on Form MO-1040, Schedule A (Nonbusiness Income). Enter the total amount of fuel tax you paid on off-road fuel during the tax year. Attach a summary of your fuel purchases—you do not need to list every receipt, but you should total the gallons and the tax paid by fuel type (gasoline versus diesel).

If you do not file an income tax return because your business income is below the filing threshold, you can file a separate fuel tax refund claim directly with the Missouri Department of Revenue. Request Form MO-1040-ES (Estimated Tax) or contact the department to ask which form applies to your situation. The department's phone number is 573-751-4541, and you can also mail a written request with your fuel purchase records.

Mail your completed form and supporting documents to the Missouri Department of Revenue, P.O. Box 311, Jefferson City, MO 65105. Keep a copy for your records. The state will send you a confirmation letter once it receives your claim.

What records you need to keep and how to organize them

The Missouri Department of Revenue requires proof of fuel purchases. This means receipts from gas stations, fuel suppliers, or farm co-ops that show the date, number of gallons, price per gallon, and total amount paid. If you buy fuel in bulk from a supplier, an invoice with these details is acceptable. Credit card statements alone are not enough—you need the actual receipt or invoice that shows the fuel quantity.

Organize your records by month or by fuel type (gasoline separate from diesel). Create a straightforward spreadsheet or handwritten log that totals the gallons and tax paid for each fuel type across the year. For example: "January gasoline: 150 gallons at 17.3 cents = $25.95 tax." This summary makes it easier for the state to verify your claim and speeds up processing.

Keep original receipts for at least three years after you file your claim. The state may audit your return and ask to see the actual documents. If you cannot produce them, the refund may be denied or reduced.

Timeline for receiving your refund

If you claim the refund on your income tax return, it will be processed as part of your overall tax return. The state typically issues refunds within 30 to 60 days of approving your return, though this can vary depending on whether the return is selected for review. If you owe other taxes, the fuel tax refund may be applied as a credit first.

If you file a separate fuel tax refund claim (not on an income tax return), the Missouri Department of Revenue usually processes it within 45 to 60 days. You will receive a check by mail or, if you provided banking information, a direct deposit to your account.

Do not expect an when ready response. The state receives many claims, especially during tax season (January through April). If you have not heard back within 90 days, contact the Department of Revenue at 573-751-4541 to check the status of your claim.

Common reasons refund claims are denied or delayed

The most common reason for denial is insufficient documentation. If your receipts do not clearly show the fuel type, quantity, or date, the state may ask for more information or deny the claim. Vague records like "fuel purchase $50" without gallons or dates will not be accepted.

Another reason is claiming fuel used on public roads. If the state suspects any of your fuel was used for highway driving, it may reduce or deny the refund. Be clear in your records about the purpose of each purchase—for example, "50 gallons diesel for grain dryer" rather than just "50 gallons diesel."

Claims filed more than one year after the tax year ends are typically rejected. If you used fuel in 2022, you must file the refund claim by the end of 2023. After that, the state considers the claim time-barred and will not process it.

Incomplete forms or missing signatures also cause delays. Make sure your name, address, and tax identification number are correct and legible. If filing jointly, both spouses must sign the return.

What to do if your claim is denied

If the Missouri Department of Revenue denies your claim, you will receive a letter explaining the reason. Read it carefully—it will tell you whether the issue is missing records, ineligible fuel use, or something else.

If you believe the denial is wrong, you can request a reconsideration. Write a letter to the Department of Revenue explaining why you disagree and include any additional documentation you have. Send it to the same address where you filed your original claim: P.O. Box 311, Jefferson City, MO 65105. Include your name, tax ID, and the year of the claim.

If the department denies your reconsideration request, you have the right to file a protest with the Missouri Administrative Hearing Commission. This is a formal appeal process. The commission will review your case and the department's decision. You can represent yourself or hire a tax professional. Contact the commission at 573-751-4962 for instructions on how to file.

Frequently Asked Questions

Can I claim a refund for fuel I bought more than a year ago?

No. Missouri allows refunds only for fuel purchased in the current or when ready prior tax year. If you bought fuel in 2022 and did not claim it by the end of 2023, you cannot file for it now. The state considers claims filed after that important date time-barred.

What if I use the same fuel for both highway and off-road purposes?

You can only claim a refund on the portion used for off-road purposes. If you cannot separate the two, estimate the percentage used off-road and explore that percentage to your total fuel purchases. Keep notes explaining how you arrived at the estimate. The state may ask you to justify it.

Do I need to file a separate form or can I claim it on my regular tax return?

If you file a Missouri income tax return, you report the refund on Form MO-1040, Schedule A. If you do not file an income tax return, you file a separate claim with the Department of Revenue. Ask the department which form to use for your situation.

What happens if I cannot find all my receipts?

You will need to reconstruct your records as best you can. Gather any receipts you have, credit card statements, and bank records showing fuel purchases. Create a summary showing what you can document. The state may reduce your refund to match only the documented amount, or it may deny the claim if documentation is too sparse.

Can I claim a refund if I am a sole proprietor or LLC?

Yes, if your business purchased fuel for off-road use. Report the refund on your business tax return or file a separate claim with the Department of Revenue. The process is the same as for individual farmers—you need receipts and a summary of fuel purchases by type.
