Frequently Asked Questions

Ad valorem tax is an annual tax on motor vehicles based on the vehicle's fair market value. The tax is calculated using the millage rate set by the county where the vehicle is registered.

Millage rates are set by local governments (counties, cities, school boards) and can vary. They are expressed in mills, where 1 mill equals $1 per $1,000 of assessed value.

The formula is: (Vehicle Fair Market Value / 1,000) × Millage Rate = Annual Ad Valorem Tax.
