What counts as the purchase price
The fee is $10 plus 5% of the purchase price. Iowa's rules exclude a few things you might expect to be taxed: a trade-in allowance (when the names on both titles match), cash discounts, a manufacturer's rebate applied to the price and dealer document fees. Freight is included. The full trade-in value counts even if part of it pays off a loan.
A rebate that comes as a credit card or check after the sale, rather than off the price, doesn't reduce the fee.
