Do you have to pay use tax when you buy a car in California but live in AZ?

Yes, if you buy a car in California but live in Arizona, you are generally required to pay use tax in Arizona when you register the vehicle there. The use tax is based on the purchase price of the car, and it helps ensure that residents contribute to state revenue. However, you may receive a credit for any sales tax paid in California, so it’s important to check both states’ tax regulations. Always consult with the Arizona Department of Revenue for specific guidance.
