Georgia Form ST-8 is the one-page certificate a nonresident buyer signs to purchase a motor vehicle in Georgia without paying the state’s four percent sales tax. You fill it in at the dealership or private sale, swear under penalty of perjury that you will take the vehicle straight out of Georgia and register it in your home state, and the seller keeps it on file as proof the exemption was legitimate. The form itself is short. The attestation on it is the serious part.
Who Can Sign It
The exemption under O.C.G.A. § 48-8-3(44) is narrow. It covers motor vehicles sold to nonresident purchasers who will immediately transport the vehicle to another state where it must be registered. A nonresident, for this purpose, is an individual domiciled in another state or a business with its principal location outside Georgia at the time of purchase.
What matters is where you actually live, not which state issued the license in your wallet. If you have already moved to Georgia and established residency, you likely do not qualify even if your out-of-state ID has not expired yet. Georgia residents cannot use the form, and planning to move out of state soon after the purchase does not help.
One other boundary worth knowing: the exemption applies to motor vehicles as defined under O.C.G.A. § 48-5-440, meaning cars, trucks, motorcycles, and similar titled vehicles. Boats, untitled trailers, and off-road equipment are governed by different rules. If you came looking for a general-purpose Georgia exemption certificate for business purchases or resale, you want Form ST-5 instead; ST-8 is for nonresident vehicle buyers only.
Filling Out the Form
Every field on the ST-8 matters, because a dealer who accepts an incomplete certificate takes on the risk of owing the uncollected tax. Expect the sales office to check your entries carefully before releasing the vehicle.
You will provide:
- Your full legal name, or your business’s legal name, exactly as it will appear on the registration.
- Your out-of-state home address. This is the field the state uses to confirm you are not a Georgia resident, so use the address you actually live at, not a mailing drop or vacation property.
- The date the sale closes.
- The vehicle’s make, model, year, and vehicle identification number or serial number. The statute specifically requires the make, model, and serial number to appear on the affidavit the seller keeps, so double-check the VIN against the vehicle itself before signing.
- The state where you will register and operate the vehicle. You are filling in a blank that completes your sworn statement about where the vehicle is going.
- Your signature and the date. The signature line sits directly under a declaration that you are signing under penalties of perjury, that everything on the form is true, and that you will immediately transport the vehicle out of Georgia and register it at home.
There is no fee, and you do not need a Georgia sales tax number. The dealer may ask for your driver’s license or other proof of out-of-state residency; that is their own due diligence, not a requirement of the form.
What “Immediately Transport” Actually Requires
The sworn language on the ST-8 commits you to immediately transporting the vehicle out of Georgia. The Georgia Consumer Protection Division has confirmed the certificate requires the purchaser to affirm immediate transport and home-state registration. Most dealers read this as meaning the vehicle leaves within a day or two of the sale, not that you must cross the state line in the next hour. A short delay while the dealer preps the vehicle is normal.
What breaks the exemption is parking the car at a Georgia second home for a few months and registering it later, or treating it as a Georgia-based vehicle while claiming on paper that you intended to drive it home. That pattern undermines the basis for the exemption and can expose both you and the seller to liability.
What the Dealer Does With the Form
The ST-8 is not filed with the Georgia Department of Revenue. The seller keeps the completed original. Under Georgia administrative rules, all of a dealer’s gross sales are presumed taxable unless the dealer holds a valid exemption certificate from the buyer, and sales without one are treated as retail sales with the dealer liable for the uncollected tax.
That is why reputable dealerships will not release a vehicle on a half-finished certificate. A missing VIN, an unsigned line, or a Georgia address in the purchaser field can invalidate the certificate during an audit and leave the dealer owing the tax. If you are buying from a private seller rather than a dealership, the same logic applies to them, and they should insist on a properly completed form.
Keep Your Own Copy and Plan for Use Tax at Home
Keep a copy of the signed ST-8 with your bill of sale. Your home state’s department of motor vehicles will almost certainly ask for proof of purchase when you register the vehicle, and having documentation that you did not pay Georgia sales tax clarifies what you owe at home.
Because skipping the Georgia tax does not mean skipping tax altogether. Nearly every state imposes a use tax on vehicles bought out of state, assessed when you title and register at home. Most states give credit for sales tax actually paid to another state, which can reduce or wipe out the use-tax bill. Since the ST-8 exempts you from paying Georgia tax entirely, you have no credit to apply and will owe your home state’s full rate. A vehicle that looks cheaper because you avoided Georgia’s four percent may cost more once your home state charges five or six at the tag office. Run that math before you sign.
What Happens If You Get It Wrong
The perjury declaration is not decorative. Providing false information on the ST-8, such as claiming nonresident status when you actually live in Georgia, carries the legal weight of lying under oath. On top of any criminal exposure, the Department of Revenue can assess the full amount of unpaid sales tax, plus interest and penalties.
Dealers are exposed too. If an audit turns up an obviously invalid ST-8, with the wrong address format, missing vehicle information, or no signature, the department can hold the dealer liable for the tax that should have been collected. Without a valid certificate, the sale is treated as a taxable retail transaction.
Where to Download Form ST-8
The current version of Form ST-8 is available on the Georgia Department of Revenue website, on the page titled “ST-8 Certificate of Exemption for Nonresident Purchase of a Motor Vehicle.” Dealerships usually keep blank copies on hand, but pulling the PDF yourself ahead of time lets you review the fields and gather what you need, especially the VIN and the exact address you will put on the registration, before you sit down to close the sale.
