Would you pay the sales tax for your own state if buy a car in different state?

It depends on the specific laws of the states involved. In general, you would pay the sales tax for your own state when you register the vehicle there, even if you purchased it in a different state. However, some states may have reciprocity agreements with other states, which may allow you to avoid paying sales tax in your home state if you purchase a vehicle in a state with a lower sales tax rate. It's important to research the specific laws and regulations of your state and the state where you are purchasing the vehicle to determine the exact tax liability.
