I have only researched ONE state and it is not either of the states you mention.
In the state I researched ... IF You pay Sales Tax at the point of purchase. Save your receipt, showing the amount of Tax you paid. And when you go to TITLE the vehicle they will take that much off your Home state taxes up to the amount of your homne state.
IE: If you pay 4% at point of purchase and your honme state is six percent you pay the other two when you title
If your honme state is 4 percent and the point of purchase is six. you pay NOTHING tax wise at tine of title.. Sadly you do not get a refund.
