What the Georgia gas tax refund is

Georgia's gas tax refund is money the state returns to businesses and farmers who buy fuel for off-road use — like tractors, generators, construction equipment, or heating oil for farm buildings. You pay the regular state gas tax when you buy the fuel, then you file a form with the Georgia Department of Revenue to get that tax back. The state does not refund federal gas tax, only Georgia's portion.

This refund exists because Georgia taxes all fuel sold at the pump, but the state does not want to tax fuel that never touches a public road. If you are running a business or farm and buying diesel or gasoline for equipment that stays off-road, you should know about this refund — it can add up over a year.

Key Takeaways

  • Georgia refunds state gas tax on fuel used in off-road equipment like farm tractors, generators, and construction machinery, but not on fuel for vehicles driven on public roads.
  • You must file Form ST-5 (Claim for Refund of Motor Fuel Tax) with the Georgia Department of Revenue, along with records showing what fuel you bought and how you used it.
  • The refund covers only Georgia's state tax, not the federal excise tax that is part of every gallon you buy.
  • You can file a claim once a year or once a quarter, depending on how much fuel you use, and the state typically processes refunds within 30 to 60 days.

Who can request a gas tax refund in Georgia

You can request a refund if you own or operate a business or farm in Georgia and you buy fuel for equipment that does not run on public roads. This includes farmers using diesel in tractors and irrigation pumps, construction companies fueling generators and compressors on job sites, manufacturers running equipment in factories, and landscaping businesses with off-road machinery.

You cannot get a refund for fuel used in vehicles registered for road use — cars, trucks, or equipment that leaves the property and travels on public highways. The refund is only for fuel that stays on your property or on private land where you have permission to operate.

How to file a claim with the Georgia Department of Revenue

Start by getting Form ST-5 from the Georgia Department of Revenue website or by calling their motor fuel tax line. You will need to fill in your business name, tax ID number, and details about the fuel you bought — the dates, quantities, and what equipment used it.

Attach receipts or invoices from fuel purchases to prove how much you bought and when. You do not need to list every single fill-up, but you do need records that show the total amount of fuel you purchased during the period you are claiming. Mail the completed form and your supporting documents to the address listed on the form.

The Georgia Department of Revenue will review your claim and send you a check if everything matches their records. Processing usually takes 30 to 60 days, though it can take longer if the department needs more information from you.

What records you need to keep

Keep fuel purchase receipts or invoices that show the date, amount, and type of fuel (diesel, gasoline, or other). You do not need to keep every receipt forever — the state typically looks back one year when you file a claim. However, it is smart to keep records for at least three years in case the department asks questions later.

If you buy fuel in bulk or have a fuel account with a supplier, a monthly statement showing total gallons purchased works just as well as individual receipts. The key is being able to show that the fuel you are claiming was actually purchased and used in Georgia during the period on your form.

How often you can file and when to file

You can file a claim once a year or once a quarter — the choice depends on how much fuel you use and how you want to manage your refunds. Many small farms file once a year at the end of the calendar year, while larger operations file quarterly to spread out the paperwork and get refunds more often.

There is no important date to file a claim for the current year, but the state will only refund fuel tax you paid within the last three years. If you wait too long, you lose the right to claim older fuel purchases. Filing sooner rather than later also means you get your money back faster.

What happens if you claim fuel you actually used on roads

If you claim a refund for fuel that was actually used in a vehicle on public roads, you are committing tax fraud. The Georgia Department of Revenue can audit your claim, and if they find you falsely claimed fuel, you will have to repay the refund plus penalties and interest. In serious cases, the state can pursue criminal charges.

The department sometimes cross-checks claims against vehicle registration records and fuel supplier reports, so misrepresenting your fuel use is a real risk. Keep your records honest and only claim fuel that genuinely stayed off-road.

Frequently Asked Questions

Can I get a refund for heating oil I buy for my farm building?

Yes. Heating oil for farm buildings, barns, or other structures counts as off-road fuel use. You will need a receipt showing you bought the oil and proof that it was used in a heating system on your property, not in a vehicle.

What if I use the same equipment sometimes on roads and sometimes off-road?

You can only claim a refund for the fuel you can document was used off-road. If equipment moves between on-road and off-road use, keep separate fuel records or estimate the percentage of fuel used off-road and claim only that portion. The department may ask you to explain how you calculated it.

Do I need a special license or permit to buy tax-free fuel in Georgia?

No. You buy fuel at the regular pump price and pay the tax, then file the refund claim later. Georgia does not have a dyed fuel or tax-exempt fuel program like some states do — you always pay at the pump and claim the refund afterward.

How long does it take to get my refund check?

The Georgia Department of Revenue typically processes refund claims within 30 to 60 days of receiving a complete form with supporting documents. If the department needs more information, processing takes longer. You can call their motor fuel tax line to check the status of your claim.

What if I did not keep all my fuel receipts?

You will need some documentation to support your claim. If you have a fuel account statement or credit card statement showing fuel purchases, that can work. The department may also accept a written statement from your fuel supplier confirming how much you bought during the period. Call the Georgia Department of Revenue to ask what they will accept before you file.
