Sales tax on a car in Alabama
Alabama charges a state sales tax of 2% on vehicle purchases.
County and city sales taxes also apply to vehicle sales, and the rates vary by location.
The 2% state rate is a special automotive rate; the general state rate is 4%. A buyer who purchases from a private seller pays state and local use tax at the same rates when registering the vehicle with the county licensing official.
Does a trade-in lower the tax?
When a vehicle is traded in on the purchase of a new or used vehicle, sales tax is charged on the net difference.
Example, state tax only. On a $30,000 car with a $10,000 trade-in, the taxable amount is $20,000, so the state tax is about $400. Without the trade-in it would be $600. Local taxes and fees are extra.
Dealer doc fees in Alabama
We could not confirm from an official source whether the state limits the documentation fee. Ask the dealer for the fee in writing and compare it with other dealers.
The documentation fee is taxed along with the vehicle.
Whatever the rule, the fee is part of your out-the-door price. Ask for it in the written quote and negotiate the total, not the line. See dealer fees explained.
Title and registration
Titles and registrations are handled by the Alabama Department of Revenue, Motor Vehicle Division. A buyer has 20 calendar days from the date of purchase to register the vehicle at the license plate issuing office in the county of residence. A title application must be submitted first if the vehicle requires a title.
Also worth knowing
- Alabama law does not provide for emissions testing of motor vehicles.
- The vehicle must be covered by an Alabama liability insurance policy before it can be registered.
- The Alabama Department of Revenue treats dealer fees such as doc fees, clerical fees, and processing fees as taxable at the automotive rate.
