Honest Car Sales

Viv asked:


If sales taxes had already been paid when the car was new, do they need to be paid again? I know on used car sales between private parties no sales tax is assessed, but how about on a used car purchase from a dealership, i.e. Nissan, Ford, etc..

I have seen sales tax returns for car sales, and to my understanding, resale/wholesale is non-taxable, for sales tax purposes.

Thanks in advance for your help.
AND WHY DOES THIS APPLY FOR DEALERSHIPS???

This would be on a used car purchase / sale between private parties. In Arizona, there is no sales tax when I buy a car from an individual.
