How it works

Iowa taxes the price after the trade-in allowance. On a $35,000 car with a $10,000 trade-in, tax applies to $25,000 — about $1,500 instead of the $2,100 you'd owe with no trade. Sales or use tax is collected when the vehicle is titled and registered.

Iowa's home prices are among the lowest in the country, but an above-average property tax rate set largely at the county and school-district level offsets some of that affordability. Local add-on tax rates and documentation fees vary by dealer and county, so treat the preset rate as a starting point and confirm the exact figure on your paperwork.
