Part of vehicle registration can be deducted in the Itemized Deductions on the personal property tax line. Only the state tax charged based on the value of the property is deductible.
Your state charges a yearly motor vehicle registration tax of 1% of value plus 50 cents per hundred weight. 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.
