What the Georgia gas tax refund is
Georgia's gas tax refund is a payment from the state to businesses and certain vehicle operators who buy fuel for off-road use. The state taxes all gasoline and diesel sold at the pump, but it refunds that tax to people who use fuel in ways that don't involve driving on public roads—farming equipment, construction machinery, boats, generators, and similar uses. The refund comes from the Georgia Department of Revenue and is based on the amount of fuel you bought and reported during a calendar quarter.
This is not a refund for what you paid at the gas station. You don't get money back from your receipt. Instead, you file a claim with the state showing how much off-road fuel you bought, and the state sends you a check for the tax portion of those purchases. The refund rate changes with the state fuel tax rate, which has been 29.1 cents per gallon for gasoline and 32.1 cents per gallon for diesel in recent years, though rates can shift if the legislature acts.
Key Takeaways
- Georgia refunds fuel tax only for off-road use—farming, construction, marine, and similar operations—not for vehicles driven on public roads.
- You must register with the Georgia Department of Revenue and file a quarterly claim form showing the amount of fuel you purchased for off-road use.
- The refund is based on the state fuel tax rate at the time you bought the fuel, and you need receipts or supplier records to prove your purchase amount.
- Claims are typically processed within 30 to 45 days of filing, and the state pays by check mailed to your address on file.
- Farmers, construction contractors, marine operators, and businesses using fuel for equipment not operated on public roads are the main groups who receive these refunds.
Who qualifies for the Georgia gas tax refund
You can claim the refund if you are a business or individual who buys fuel for equipment or vehicles that operate off public roads. This includes farmers using fuel for tractors and farm machinery, construction companies fueling bulldozers and excavators, marine operators buying fuel for boats, and businesses running generators or other stationary equipment. The key requirement is that the fuel is not used to power a vehicle driven on Georgia's public roads.
You do not need to be a large operation. A small contractor, a part-time farmer, or someone who runs a single piece of equipment can claim the refund as long as you have records showing the purchase. You must have a valid Georgia tax ID or business registration, and you must file the claim yourself—the fuel supplier does not do it for you.
How to register and file a claim
Start by registering with the Georgia Department of Revenue if you do not already have a tax account. You can register online through the Georgia Tax Center or by mail. Once registered, you will receive a tax ID number, which you need to file refund claims.
To file a claim, you use Form ST-5 (Claim for Refund of Motor Fuel Tax), which is available on the Georgia Department of Revenue website. You fill in the quarter and year you are claiming for, list the amount of fuel you purchased for off-road use, and attach copies of your receipts or fuel supplier invoices as proof. The form asks for the type of equipment the fuel powered and the number of gallons purchased. You mail the completed form and supporting documents to the address listed on the form, or you may be able to file electronically through the Georgia Tax Center if that option is available for your account type.
Claims must be filed within three years of the end of the quarter in which you bought the fuel. For example, fuel purchased in the first quarter (January through March) must be claimed by March 31 of the third year after that purchase. Filing sooner is better because it speeds up processing and reduces the chance of losing receipts.
What documents you need to gather
You will need proof that you bought the fuel and that it was for off-road use. Fuel supplier invoices are the best evidence—these show the date, the number of gallons, the price per gallon, and often the type of fuel. Credit card statements showing purchases at fuel suppliers can also work, but they are weaker proof because they do not always show the gallon amount. Receipts from gas stations are usually not accepted because they do not distinguish between on-road and off-road fuel.
Keep records organized by quarter. If you buy fuel from the same supplier regularly, ask them to provide a quarterly summary showing total gallons purchased. Some suppliers will do this without charge. If you buy from multiple suppliers, gather all invoices for the quarter and add them up. You do not need to submit original documents—copies are acceptable—but keep originals in case the state asks for verification later.
Processing time and payment method
After you mail or file your claim, the Georgia Department of Revenue typically processes it within 30 to 45 days. During this time, the state verifies that your tax ID is active, checks that your claim is within the three-year window, and reviews your supporting documents. If everything is in order, the state calculates the refund based on the fuel tax rate for that quarter and issues a check.
The check is mailed to the address on file with your tax account. If your address has changed, update it in the Georgia Tax Center before filing so the check reaches you. If you do not receive your check within 60 days of filing, contact the Georgia Department of Revenue to confirm the claim was received and processed. You can track the status of your claim by calling the department or checking the Georgia Tax Center if that tracking feature is available.
Common reasons claims are delayed or denied
The most common reason for delay is incomplete or missing documentation. If your receipts do not clearly show the gallon amount or the date of purchase, the state may ask you to resubmit with better proof. Submitting a claim after the three-year deadline will result in denial—there is no exception for late filing, so mark your calendar for the deadline of each quarter you claim.
Claims are also denied if the fuel is determined to have been used on public roads. If you claim fuel for a vehicle that is registered for road use, the state may deny the claim even if you say it was used off-road. Keep separate records for on-road and off-road fuel to avoid this problem. If your tax ID is not active or in good standing, your claim may be held until you resolve any outstanding tax issues with the state.
Frequently Asked Questions
Can I claim a refund for fuel I bought last year?
Yes, as long as it was within the past three years. For example, if you bought fuel in January 2022, you can still claim it through March 31, 2025. After that date, the claim is too old and will be denied. File as soon as you have your receipts gathered to avoid missing the deadline.
What if I lost some of my fuel receipts?
Contact your fuel supplier and ask for a statement showing your purchases during that quarter. Most suppliers keep records and can provide a summary. If the supplier cannot help, you may be able to use credit card statements or bank records showing the purchase, though these are weaker proof. The state may ask for additional documentation or deny the portion of the claim you cannot support.
Do I have to file quarterly, or can I file once a year?
You can file quarterly or accumulate claims and file once a year—the choice is yours. Filing quarterly gets you the refund sooner, but filing annually is simpler if you have only a few purchases. Either way, each claim must cover only the fuel purchased in that specific quarter.
What happens if the state denies my claim?
The state will send you a notice explaining why. If you disagree, you can file a protest within 30 days of the notice. The protest should explain why you believe the claim is valid and include any additional documentation. Send it to the Georgia Department of Revenue at the address listed on the denial notice.
Can I claim a refund for fuel used in equipment I no longer own?
Yes, as long as you have receipts showing you bought the fuel and it was for off-road use. The refund is based on the fuel purchase, not on current ownership of the equipment. You can claim fuel you bought for equipment you sold years ago, provided the three-year deadline has not passed.
