No sales tax deduction for trade-in
If you live in a state where your sales tax is calculated on your full purchase price, check this box. If this box is unchecked, sales tax is calculated on the purchase price less trade-in. Currently California, the District of Columbia, Hawaii and Michigan allow no deductions for trade-ins when calculating sales tax. In addition, Alaska, Delaware, Montana, New Hampshire and Oregon have no sales tax on autos.
