Georgia Used Car Sales Tax: How the 7% TAVT Works in 2026

Georgia doesn't charge regular sales tax on a used car. Instead you pay a one-time title ad valorem tax, or TAVT, which as of Oct 19, 2026 is 7.0% of the car's fair market value, and on a used car that value comes from the state's assessment manual, not from what you paid. You pay it at the tag office in the county where you live when you title the car. Buy from a dealer and a trade-in lowers it. Buy from a private seller and it doesn't.

I went through the Georgia Department of Revenue's TAVT pages, its FAQ and the current MV-16 family-transfer affidavit on Monday morning, October 19, 2026. The rules have been in place since March 1, 2013, when TAVT replaced both the sales tax and the yearly ad valorem tax on most vehicles bought after that date. You pay it once, at titling, and the next owner pays it again.

Why your bill of sale price may not matter

The DOR's TAVT FAQ says the fair market value of a used vehicle is "the value identified in the state motor vehicle assessment manual," figured by averaging current wholesale and retail values under O.C.G.A. 48-5-442. If the car isn't in the manual, the state uses a used car market guide the Revenue Commissioner picks.

So if you get a great deal from a private seller, the tax doesn't shrink with it. Pay $7,000 for a car the manual values at $10,000 and the TAVT is based on the $10,000: $700, not $490. That's also why writing a fake low price on the bill of sale doesn't do much here, unlike in some states. The state's TAVT Estimator on the DOR's eServices site shows the value it will use, so check it before you agree on a price. Then screenshot it.

That screenshot tip isn't paranoia. A November 15, 2013 DOR bulletin says values in the state system get updated annually, and a value can change between the sale date and the day the title work is processed. It lets county tag offices accept a date-stamped screenshot from the calculator as proof of the value on the purchase date. That bulletin is written about dealers, but a dated screenshot costs you nothing.

Trade-ins only count at a dealer

From the FAQ, word for word: "A reduction is made for the trade-in when the sale was made by a dealer, but not when the sale was made by a private individual." The trade-in value is whatever the bill of sale says the dealer gave you for it. Rough example: a used car the manual values at $18,000, with a $6,000 trade at a dealer, is taxed on $12,000, which comes to $840. Sell your old car privately and buy from another private seller and you'd pay $1,260 on the same car. The dealer also has to collect the TAVT and file your title application with your county's tag office, so you don't make that trip yourself.

Family transfers and new residents

Georgia has two lower rates that matter for used cars, both listed on the vehicle taxes page:

• Immediate family, 0.5%: if the car already has a Georgia title and TAVT was paid on it, a transfer to family is taxed at 0.5% of fair market value. The MV-16 affidavit (revised 01/2026) covers a spouse, parent, child, stepchild, sibling, grandparent or grandchild, and it applies whether the car was gifted, purchased or inherited. Both of you sign in front of a notary. Lying on it can cost up to $2,500 in state penalties plus up to $2,500 local.
• Inheritance, 0.5%: the same rate on form T-20.
• New residents, 3%: moving in with a car you already own, you pay 3% of its value. The new to Georgia page says to register within 30 days of moving.

There are also exemptions for some veterans and for certain injured first responders, on their own forms. If your family car came into Georgia under the old annual tax system, the rules differ, and you get a choice. Ask the tag office.

What to bring to the county tag office

For a car you bought from a private seller, the casual sale page lists:

• Your Georgia driver's license or ID.
• The title, signed over to you, with any liens released.
• Form MV-1, the title and tag application.
• Proof of insurance, and an emissions certificate if your county requires one.
• Money for the $18 title fee, the $20 plate fee and the TAVT.

None of that tells you what the car has been through. Check for brands on NMVTIS, decode the VIN at NHTSA vPIC, and pull a history report before money changes hands. A licensed CARFAX and AutoCheck reseller (that's us; we're not affiliated with either brand or Experian) charged around $5.50 per guest report as of mid October 2026, about $4.50 for members and about $6.75 for the bundle, against roughly $39.99 to $44.99 retail. Confirm at checkout. More on the paperwork in our Georgia title transfer guide, and the used car sales tax overview compares other states. And read up on Georgia's lemon law and used cars, because 7% is a lot to pay on a lemon.
