What is Alabama's car sales tax rate?

Alabama levies a reduced 2% state automotive sales tax on motor vehicles, lower than its 4% general sales tax rate. Counties and cities add their own automotive rates on top, so the combined rate is typically in the 2% to 5% range depending on where you register the vehicle.

Does a trade-in reduce the tax in Alabama?

Yes. Alabama taxes the net price after a trade-in allowance, so if you trade in a vehicle the dealer credits, only the difference between the new car's price and the trade-in value is subject to sales tax. Enter the trade-in amount to lower the taxable base.

Are the county and city rates the general sales tax rates?

No. Alabama localities publish a separate, usually lower automotive rate for vehicle sales that differs from their general sales tax rate. Use the automotive (auto) rate for your county and city, not the general rate, or you will overestimate the tax owed.

Where is the car sales tax paid?

For a dealer sale the dealer usually collects the tax; for a private-party purchase you pay the automotive sales tax (often called casual sales tax) to the county licensing official when you title and register the vehicle. The combined rate is based on your county of residence.

Does this include the registration and title fees?

No. This calculator computes only the sales tax on the purchase. Alabama's flat registration (tag) fee, the one-time title fee, the issuance fee, and the separate annual ad valorem property tax are additional costs you pay at the DMV on top of the sales tax shown.

Alabama charges a reduced 2% state automotive sales tax on vehicle purchases — lower than its 4% general rate — and counties and cities add their own automotive rates on top. The tax applies to the price after any trade-in allowance. This tool combines those rates to estimate what you’ll owe at registration.

How it works

The taxable amount is the price minus a qualifying trade-in, and the combined automotive rate is the sum of the state, county, and city automotive rates:

taxable     = max(0, purchase price − trade-in allowance)
combined %  = 2% (state) + county auto % + city auto %
sales tax   = taxable × combined %

Use each locality’s automotive rate, which is published separately from and is usually lower than its general sales tax rate. The trade-in credit is real in Alabama: only the net difference is taxed.

Example and notes

A 30,000 dollar car with a 10,000 dollar trade-in, in a county adding 1.5% and a city adding 1% automotive tax: the taxable base is 30,000 − 10,000 = 20,000, the combined rate is 2% + 1.5% + 1% = 4.5%, so the tax is 20,000 × 0.045 = 900 dollars. This figure is sales tax only — add the flat registration fee, title fee, issuance fee, and annual ad valorem property tax when you budget for the full DMV cost. Confirm your local automotive rates with the county licensing office, since they vary across Alabama.
