What the Georgia gas tax refund actually is
Georgia's gas tax refund is money the state returns to businesses and farmers who buy fuel for off-road use — equipment, machinery, generators, or vehicles that never touch public roads. The state taxes all gasoline at the pump, but if you use that fuel for something other than driving on a highway, you can get that tax back. The refund covers the state excise tax on motor fuel, which is separate from the federal tax.
The refund exists because the gas tax is meant to fund road maintenance. If your equipment never uses the roads, you shouldn't pay for them. A farmer running a tractor, a construction company powering a generator, or a business operating forklifts in a warehouse can all claim this money back — but only if they keep records proving the fuel went into non-road equipment.
Key Takeaways
- Georgia refunds the state excise tax on fuel used in off-road equipment, machinery, and non-highway vehicles, but not the federal tax.
- You must keep detailed records showing what equipment the fuel went into and when, or the state will deny your claim.
- The refund is claimed through the Georgia Department of Revenue, and the process requires you to file a form with your documentation attached.
- Farmers, construction companies, and manufacturers are the most common claimants, but any business using fuel off-road can request a refund.
- The refund amount depends on how much fuel you bought for off-road use and the current state excise tax rate.
Who can claim the Georgia gas tax refund
Any business or individual who buys gasoline or diesel for off-road use can claim a refund. This includes farmers using fuel in tractors and irrigation pumps, construction companies powering generators and compressors, manufacturers running forklifts and material handlers, landscaping businesses fueling equipment, and mining or quarrying operations. The key requirement is that the fuel must go into equipment that does not operate on public roads.
You do not need to be a large operation. A small business with a single generator or a farmer with one piece of equipment can claim a refund if they keep the right records. The state does not have a minimum threshold for the refund amount, but the cost of documenting and filing may not be worth it for very small quantities of fuel.
What records you need to keep
The Georgia Department of Revenue requires detailed documentation for every gallon you claim. You must keep fuel purchase receipts showing the date, amount, and price. You must also keep records of what equipment the fuel went into — this is the part most people miss. A receipt that just says "50 gallons of diesel" is not enough. You need to show that those 50 gallons went into a specific piece of equipment, like "Caterpillar 320 excavator, job site at 123 Main Street."
The best way to do this is to keep a fuel log. Write down the date, the equipment, how many gallons you put in, and the receipt number. If you buy fuel in bulk and distribute it to multiple pieces of equipment, you need to track where each portion went. Some businesses use fuel tanks with meters or keep detailed inventory records. Without this documentation, the state will reject your claim, and you will not get the refund.
How to file for the refund
You file through the Georgia Department of Revenue using Form ST-5, the Gasoline and Diesel Fuel Tax Refund Claim form. You can read it from the Georgia Department of Revenue website or request it by mail. The form asks for your business information, the period you are claiming (usually a calendar quarter or year), the total gallons of fuel used off-road, and the amount of tax you paid.
Attach your fuel receipts and your fuel log or equipment records to the form. Mail the completed form and documentation to the address listed on the form. The state processes claims in the order they arrive, and processing typically takes four to eight weeks. You will receive a check or a credit to your sales tax account, depending on what you request on the form.
The state excise tax rate and refund amounts
Georgia's state excise tax on motor fuel varies slightly depending on the type of fuel and recent legislative changes. As of 2024, the state excise tax is approximately 29.1 cents per gallon on gasoline and 32.6 cents per gallon on diesel, though these rates can change. The refund you receive is based on the tax rate that was in effect when you bought the fuel, not the current rate.
To calculate your potential refund, multiply the number of gallons you used off-road by the tax rate in effect during that period. If you used 1,000 gallons of diesel in a quarter when the rate was 32.6 cents per gallon, your refund would be approximately $326 before any adjustments. The state does not refund the federal excise tax, which is 18.4 cents per gallon on gasoline and 24.4 cents per gallon on diesel.
Common reasons claims get denied
The most common reason the state denies a refund claim is missing or incomplete documentation. If your receipts do not match your fuel log, or if you cannot prove which equipment the fuel went into, the state will ask for more information or deny the claim outright. Some businesses submit receipts without any record of how the fuel was used, which is an automatic rejection.
Another reason claims fail is mixing road and off-road fuel. If you buy fuel at a pump and use some of it in your truck (which drives on roads) and some in your generator (which does not), you can only claim the portion that went into the generator. You must be able to document this split. If your records show you bought 100 gallons but cannot prove how much went off-road, the state will deny the entire claim.
Timing and what to expect after you file
Most businesses file quarterly or annually, depending on how much fuel they use. If you file quarterly, you submit four claims per year, each covering three months of fuel purchases. If you file annually, you submit one claim covering the entire year. Quarterly filing gets you refunds faster, but it requires more paperwork.
After you mail your claim, the Georgia Department of Revenue will review it for completeness. If something is missing, they will contact you and ask for additional documentation. If everything is in order, they will process the refund within four to eight weeks. You can check the status of your claim by contacting the department directly, though they do not have an online tracking system for individual claims.
Frequently Asked Questions
Does the refund include federal gas tax?
No. Georgia only refunds the state excise tax. The federal excise tax, which is 18.4 cents per gallon on gasoline and 24.4 cents per gallon on diesel, cannot be refunded by the state. You would need to contact the federal government or a tax professional to explore whether any federal refund is available for your situation.
What if I use the same vehicle for both road and off-road work?
You can only claim a refund for the fuel that went into off-road use. If your truck is registered and drives on public roads, fuel for that truck is not refundable, even if you sometimes use it at a job site. You must separate the fuel used in road vehicles from fuel used in equipment that never leaves your property or a private site.
How far back can I claim refunds?
Georgia generally allows you to claim refunds for fuel purchased within the current and previous calendar year. If you have records from 2022 and it is now 2024, you may not be able to claim those refunds. Check with the Georgia Department of Revenue about the specific lookback period, as it can change.
What happens if I cannot find all my receipts?
The state requires actual receipts or documented proof of fuel purchases. If you have lost receipts, you may be able to use credit card statements or bank records showing fuel purchases, along with your fuel log showing how the fuel was used. However, the state may deny the claim if you cannot provide enough documentation to verify the amounts and dates.
Can I claim a refund if I buy fuel in another state?
No. Georgia only refunds tax on fuel purchased within Georgia. If you buy fuel in another state and bring it back to use in Georgia equipment, that fuel is not may be able to access for a Georgia refund. You would need to pursue any refund through the state where you purchased the fuel.
