In addition to sales tax, the buyer may also be responsible for paying a vehicle registration fee, a smog inspection fee, and a title transfer fee. These fees vary depending on the type of vehicle and the county in which the vehicle is registered.
To calculate the sales tax on a car purchase, multiply the purchase price by 7.25%. For example, if you buy a car for $10,000, the sales tax would be $725.
You can pay the sales tax online, by mail, or in person at a DMV office. If you pay online or by mail, you must include a copy of the car purchase agreement and a completed Form REG 256, Application for Title or Registration. If you pay in person, you must bring the original car purchase agreement, a completed Form REG 256, and the current registration certificate (if applicable).
