What Georgia's Ad Valorem Tax Is and Who Pays It

Ad valorem tax is a yearly tax Georgia charges on the value of your vehicle. The word "ad valorem" means "according to value" — the more your car is worth, the more tax you owe. Every vehicle registered in Georgia is subject to this tax, whether you own it outright or have a loan on it.

The tax is calculated based on the assessed value of your vehicle, not the price you paid for it. Georgia uses a depreciation schedule that reduces the taxable value each year — a new car is worth more than a five-year-old car with the same make and model. The county tax assessor's office determines the assessed value, and the tax is collected by your county.

You pay ad valorem tax when you register your vehicle with the Georgia Department of Driver Services (DDS) or renew your registration. It is not a separate bill you receive in the mail; it is built into your registration fee. If you do not pay the tax, your registration will not be processed and your vehicle cannot be legally driven.

Key Takeaways

  • Ad valorem tax is a yearly tax based on your vehicle's assessed value, collected when you register or renew your registration with Georgia DDS.
  • The tax amount depends on your vehicle's age, make, model, and condition — newer vehicles have higher assessed values and higher taxes.
  • You pay the tax to your county tax assessor's office through the registration process, not directly to the state.
  • If you move to Georgia from another state, you must pay ad valorem tax starting with your first Georgia registration, even if you did not pay it in your previous state.
  • Vehicles registered as classic cars, farm equipment, or government-owned may be exempt or taxed differently — check with your county assessor if your vehicle falls into a special category.

How the Tax Amount Is Calculated

Georgia uses a standard depreciation table to determine your vehicle's assessed value. A brand-new vehicle is assessed at 100 percent of its market value. After the first year, the assessed value drops to 85 percent. It continues to decline each year — at year 10, a vehicle is assessed at roughly 30 percent of its original value. After 10 years, the assessed value stays flat and does not decrease further.

The tax rate itself varies by county. Most Georgia counties charge between 7 and 8 mills per dollar of assessed value (a mill is one-tenth of a cent). This means if your vehicle's assessed value is $20,000 and your county's rate is 7.5 mills, your yearly ad valorem tax would be $150. The exact rate depends on where your vehicle is registered.

You can find your county's current tax rate by calling your county tax assessor's office or visiting their website. The Georgia Department of Revenue also publishes a list of county rates, though rates can change year to year. When you register your vehicle, the DDS office will calculate the tax owed based on your vehicle's information and your county's rate.

When You Pay Ad Valorem Tax

You pay ad valorem tax at the time of vehicle registration or registration renewal. If you are registering a vehicle in Georgia for the first time — whether it is new to you or you are moving to the state — you will owe ad valorem tax as part of the registration process. The tax covers the 12-month registration period.

If you are renewing an existing Georgia registration, you pay the tax again. Georgia registration periods vary — some are one year, some are two years, and some are three years, depending on your vehicle type and when you first registered it. You will receive a renewal notice before your registration expires, and the notice will show the ad valorem tax amount due.

If you sell your vehicle before the registration period ends, you do not get a refund of the ad valorem tax you already paid. The tax is tied to the registration period, not to your ownership of the vehicle. The new owner will need to register the vehicle in their name and will owe tax for their own registration period.

Vehicles That May Be Exempt or Taxed Differently

Not all vehicles pay the standard ad valorem tax. Classic or antique vehicles — typically those at least 25 years old — may may have access to for a reduced tax rate or exemption, depending on your county. You must register them as classic vehicles with the DDS, and they usually cannot be used for regular commuting.

Farm equipment and vehicles used primarily for agricultural purposes may be exempt or taxed at a lower rate. Government-owned vehicles — those registered to federal, state, or local agencies — are typically exempt. Disabled veteran vehicles may also receive an exemption or reduction, though the rules vary by county.

If your vehicle falls into one of these categories, contact your county tax assessor's office before you register. They can tell you whether your vehicle qualifies for an exemption or reduced rate and what documentation you need to provide. Claiming an exemption you are not may have access to to can result in penalties and back taxes owed.

What Happens If You Do Not Pay Ad Valorem Tax

If you do not pay ad valorem tax, your vehicle registration will not be issued or renewed. You cannot legally drive an unregistered vehicle in Georgia. If you are stopped by law enforcement, you face a fine for driving without a valid registration, and your vehicle can be impounded.

If you owe ad valorem tax from a previous year and did not pay it, you will owe that amount plus any penalties and interest before you can renew your registration. The amount owed accumulates, so the longer you wait, the more you will owe. Your county tax assessor's office can tell you the total amount due if you are unsure.

If you believe you were charged ad valorem tax in error — for example, if your vehicle should have been exempt — you can file a protest with your county tax assessor. You must do this within a set time frame, usually 30 days of receiving your tax bill or registration notice. Contact your county assessor's office for the specific important date and process in your area.

Ad Valorem Tax When You Move to Georgia

If you move to Georgia from another state and bring a vehicle with you, you must register it in Georgia and pay ad valorem tax. Many other states do not charge an annual property tax on vehicles, so this may be new to you. You cannot keep your out-of-state registration and drive legally in Georgia — you have 30 days to register your vehicle with the Georgia DDS.

When you register, you will owe ad valorem tax based on your vehicle's assessed value in Georgia, using the depreciation schedule described above. The tax is calculated from the date you register, not from the date you moved to the state. If you register in the middle of the year, you may owe a prorated amount for the remainder of that registration period.

Bring your out-of-state title, proof of insurance, and a valid ID when you register. You will also need to pass a Georgia safety inspection if your vehicle is more than a certain age (rules vary). The DDS office will calculate your ad valorem tax and include it in your total registration fee.

How to Find Your County's Tax Rate and Assessor

Your county tax assessor's office is the source for information about ad valorem tax rates, assessed values, and exemptions. You can find contact information by searching "[your county name] tax assessor" online or by calling your county government office. Most counties have a website with tax rates, forms, and frequently asked questions.

The Georgia Department of Revenue publishes a directory of county tax assessors and current tax rates on its website. You can also call the DDS at 678-413-8400 during business hours to ask about your county's rate or to find your assessor's contact information.

If you are registering a vehicle online through the DDS website, the system will calculate your ad valorem tax automatically based on your vehicle's information and your county. You will see the tax amount before you complete your payment, so you know exactly what you owe.

Frequently Asked Questions

Can I get a refund if I sell my car before my registration expires?

No. Ad valorem tax is tied to the registration period, not to your ownership. Once you pay it, it does not refund if you sell the vehicle early. The new owner will register the vehicle in their name and pay their own ad valorem tax for their registration period.

What if my vehicle's assessed value seems too high?

You can file a protest with your county tax assessor if you believe the assessed value is incorrect. You must do this within 30 days of receiving your tax bill or registration notice. Bring documentation such as recent repair bills, maintenance records, or a professional appraisal showing the vehicle's actual condition and value.

Do I pay ad valorem tax on a financed vehicle?

Yes. Whether you own the vehicle outright or have a loan on it, you owe ad valorem tax. The lender does not pay it — you do, as part of your registration. If you do not pay, your registration will not be issued, and the lender may report the vehicle as unregistered.

Is ad valorem tax the same as sales tax?

No. Sales tax is a one-time tax you pay when you buy a vehicle. Ad valorem tax is a yearly tax you pay to keep your vehicle registered. Both explore in Georgia — you pay sales tax at purchase and ad valorem tax every year you own and register the vehicle.

What if I register a vehicle that was previously registered in another Georgia county?

If you move within Georgia and transfer your registration to a new county, your ad valorem tax rate may change because each county sets its own rate. Your new county's assessor will calculate the tax based on their rate. Contact your new county's tax assessor to find out the rate before you transfer your registration.
