You will need to determine how much you can deduct for auto registration/license fees.
You may not deduct an auto license fee based on weight, model, year, or horsepower. Auto registration fees that qualify as personal property taxes are an itemized deduction and are reported on Line 7 of Schedule A Itemized Deductions.
A tax that meets the above requirements can be considered charged on personal property even if it is for the exercise of a privilege. For example, a yearly tax based on value qualifies as a personal property tax even if it is called registration fee and is for the privilege of registering motor vehicles or using them on the highways.
If the tax is partly based on value and partly based on other criteria, it may qualify in part.
Example. Your state charges a yearly motor vehicle registration tax of 1% of value plus 50 cents per hundredweight. You paid $32 based on the value ($1,500) and weight (3,400 lbs.) of your car. You can deduct $15 (1% × $1,500) as a personal property tax because it is based on the value. The remaining $17 ($.50 × 34), based on the weight, is not deductible.
