Who can file for a Missouri gas tax refund and what you need
Missouri allows certain businesses and organizations to claim a refund on fuel tax they paid on gasoline and diesel. The refund applies to fuel used for specific purposes — mainly off-road business use, agricultural operations, and certain non-profit activities. You cannot claim a refund on fuel used for regular highway driving, even if it was for business.
To file, you need to be registered with the Missouri Department of Revenue and have kept records of the fuel purchases you're claiming. This means receipts, invoices, or fuel purchase records that show the date, amount, and type of fuel. You'll also need to know how much fuel tax you paid — this is included in the price at the pump, currently 17 cents per gallon for gasoline and 17 cents per gallon for diesel in Missouri.
The refund is available to farmers, construction companies, manufacturers, and other businesses that use fuel off-road. Non-profit organizations and government entities may also be may be able to access, depending on how they use the fuel. If you're unsure whether your use qualifies, contact the Missouri Department of Revenue directly before filing.

How to file your claim with the Missouri Department of Revenue
Start by obtaining Form MO-1, which is the official Claim for Refund of Motor Fuel Tax. You can download this form from the Missouri Department of Revenue website or request it by phone at 573-751-4541. The form asks for your business name, tax identification number, the reporting period (usually a calendar quarter), and a detailed breakdown of the fuel you purchased.
Fill in the form with the total gallons of fuel purchased during the period you're claiming, the tax rate that applied, and the total tax amount. Attach copies of your fuel purchase records — receipts, invoices, or credit card statements that show the fuel purchases. The Department needs to see proof that you actually bought the fuel and paid the tax.
Mail the completed form and supporting documents to the Missouri Department of Revenue, Motor Fuel Tax Section, P.O. Box 311, Jefferson City, MO 65105. Include a cover letter with your contact information and phone number. Keep a copy of everything you send for your records.
Timeline and what to expect after filing
After the Department receives your claim, allow four to eight weeks for processing. This timeline assumes your claim is complete and accurate. If the Department finds missing information or questions your documentation, they will contact you — this can add two to four weeks to the process.
The Department will review your fuel purchase records to confirm that the fuel was actually used for a may have access to purpose. They may ask for additional documentation, such as equipment logs, mileage records, or a written statement describing how the fuel was used. Respond to any requests promptly to avoid further delays.
Once approved, the refund is issued by check mailed to your address on file. The check typically arrives within one to two weeks after final approval. If you have not received your refund within ten weeks of filing, contact the Motor Fuel Tax Section to check the status.
What counts as off-road fuel use in Missouri
Off-road fuel use includes operating equipment and vehicles that do not travel on public highways. This covers farm equipment like tractors, combines, and irrigation pumps; construction equipment such as bulldozers, excavators, and concrete mixers; and manufacturing equipment powered by fuel engines. Fuel used to heat buildings or power stationary generators may also may have access to, depending on the specific use.
Agricultural use is broadly defined and includes any fuel used in farming operations — plowing, planting, harvesting, hauling crops within the farm, and powering farm buildings. Fuel used to transport crops or goods to market on public roads does not may have access to, even if the vehicle is owned by a farm.
Fuel used for any highway driving — including driving to and from job sites, transporting goods for sale, or commuting — is not refundable. The key distinction is whether the vehicle or equipment leaves the property or stays within a defined work area.
Keeping records that will pass Department review
The Missouri Department of Revenue requires specific documentation to support your refund claim. Keep original receipts or invoices for every fuel purchase you claim, showing the date, gallons purchased, price per gallon, and total cost. Credit card statements alone are not sufficient — you need the actual fuel pump receipt or the supplier's invoice.
Organize your records by month or quarter to match the period you're claiming. Create a simple spreadsheet listing each purchase date, gallons, tax paid, and the equipment or operation the fuel was used for. This makes it easier to total your claim and helps the Department verify your numbers quickly.
If you buy fuel in bulk or through a fuel supplier account, request itemized invoices that break down the tax separately from the fuel cost. Some suppliers include tax in the total price without showing it separately — in that case, calculate the tax yourself using the current rate (17 cents per gallon) and note this on your claim form.
If your claim is denied or incomplete
If the Department denies your claim, they will send a written explanation stating the reason. Common reasons for denial include missing documentation, fuel use that does not meet the off-road definition, or records that do not clearly show the fuel was purchased during the claimed period.
You have the right to appeal a denial. File a written appeal with the Missouri Department of Revenue within 60 days of the denial letter, including any additional documentation or explanation. The appeal goes to the Department's administrative review section, which will reconsider your claim.
If the Department requests additional information before making a decision, respond within 30 days. Failure to respond may result in a denial. If you need more time, contact the Motor Fuel Tax Section and request an extension in writing.
