Which tax must be included in an advertised price for a motor vehicle?

Answer: C — Sales tax

The amount advertisers must show with a motor vehicle is the tax tied directly to the sale. Sales tax is collected by the dealer at the time of purchase and added to the price, so the total cost a buyer sees in an advertisement should include this tax. Income tax and property tax aren’t charged by the dealer as part of a vehicle sale, and the motor vehicle excise tax is usually paid when you register the vehicle later, not included in the advertised sale price. So the tax that must be included in an advertised price is sales tax.
