You may be able to deduct certain taxes on your federal return for the fees you pay for your vehicle registration or vehicle license. You'll find this information on your vehicle registration bill.
The total amount of your registration fee is not deductible, just the portion that the state charged you for taxes based on the value of your vehicle. If you need help finding this on your bill, contact your state's Department of Motor Vehicles.
Not all states charge a tax based on the vehicle's value.
Hope this helps!
