How do you calculate the ad valorem on auto?

To calculate the ad valorem tax on an automobile, first determine the assessed value of the vehicle, which is typically a percentage of its market value based on local tax regulations. Next, find the local ad valorem tax rate, usually expressed as a percentage. Multiply the assessed value by the tax rate to determine the tax amount owed. For example, if the assessed value is $20,000 and the tax rate is 2%, the ad valorem tax would be $400.
