Sales Tax is a tax levied by state or local governments. In most areas, a car lease is considered the same as a purchase. So you’ll pay sales tax on your purchase. That’s one reason to think carefully about where you purchase or lease your vehicle. You might only pay 7.5 percent sales tax instead of 8.75 percent depending on where you buy or lease your car. And when you’re talking about a $20,000 car, saving 1.25 percent means saving $250.
