Understanding Georgia Vehicle Ad Valorem Tax
In Georgia, the Ad Valorem tax (often called "Taxicab" or "Tag Tax") is an annual tax you pay on your vehicle. It's levied by your county and is based on the fair market value of your vehicle. This is different from sales tax, which you pay when you initially purchase a vehicle. The Ad Valorem tax is essentially a property tax on your vehicle.
How is the Ad Valorem Tax Calculated?
The calculation involves several key factors:
Vehicle's Fair Market Value: This is the primary basis for the tax. The Georgia Department of Revenue determines this value, often referencing industry guides like the NADA Guide.
Vehicle Type: Different vehicle types (cars, trucks, motorcycles, RVs, trailers) may have different millage rates or depreciation schedules.
Vehicle Model Year: The tax amount decreases as the vehicle ages due to depreciation. Georgia uses a schedule to depreciate the vehicle's value over time.
County Millage Rate: Each county in Georgia sets its own millage rate, which is a tax rate expressed in mills (a mill is one-tenth of a cent, or $0.001). This rate is applied to the depreciated value of your vehicle.
The Georgia Ad Valorem Tax Formula
The general formula for calculating Georgia's Ad Valorem tax is:
Tax = (Depreciated Value) * (Millage Rate)
Where:
Depreciated Value: This is calculated by applying a depreciation schedule to the vehicle's initial fair market value. Georgia law specifies depreciation rates based on the vehicle's age.
Millage Rate: This is the specific rate set by your county. It's often an aggregate of rates from various local taxing entities (county, city, school district).
For this calculator, we are using a simplified depreciation schedule and an assumed average millage rate for demonstration purposes. The actual tax may vary based on your specific county's millage rates and any local variations in depreciation application.
Depreciation Schedule (Simplified for this Calculator)
Georgia uses a tiered depreciation schedule. The following is a simplified representation:
Year 1: 85% of initial value
Year 2: 70% of initial value
Year 3: 60% of initial value
Year 4: 50% of initial value
Year 5: 40% of initial value
Year 6: 30% of initial value
Year 7: 25% of initial value
Year 8: 20% of initial value
Year 9: 15% of initial value
Year 10+: 10% of initial value
Assumed Millage Rate
For this calculator, we are using an assumed average millage rate of 9.5 mills (0.0095). This is a national average and your actual rate will depend on your specific Georgia county. You can usually find your county's millage rate on your county tax assessor's website.
How to Use the Calculator
1. Vehicle's Current Fair Market Value: Enter the current estimated value of your vehicle. You can often find this information on websites like Kelley Blue Book (KBB) or NADA Guides.
2. Vehicle Type: Select the appropriate category for your vehicle.
3. Vehicle Model Year: Enter the year the vehicle was manufactured.
4. Current Year: Enter the current calendar year to determine the vehicle's age.
5. Click "Calculate Tax" to see your estimated Ad Valorem tax.
Disclaimer: This calculator provides an estimate based on simplified depreciation schedules and an average millage rate. Your actual Ad Valorem tax may differ. For precise figures, consult your local county tax assessor's office or the Georgia Department of Revenue.
