The deduction is part of the American Recovery and Reinvestment Act of 2009 and applies to taxes paid on up to $49,500 of the purchase price for qualified new cars, light trucks, motorcycles or motor homes. Generally, vehicles weighing 8,500 pounds or less qualify. This means that most new cars and many new trucks will qualify. New motor homes qualify regardless of weight.
Buyers are entitled to a partial deduction if they earn between $125,000 and $135,000 ($250,000 and $260,000 for joint filers). The deduction is eliminated for those who earn over these amounts.
To qualify the vehicle must be new and purchased in 2009 after Feb. 16 and no later than Dec. 31. There is still time left but the clock is ticking.
