I bought a new car in Florida and paid "Vermont" tax. Now I have sold my old car, can I get a tax refund?
No, not from Vermont.
Several states, including Florida, will collect taxes equal to the rate of your home state. In this example, the Vermont tax is 6%, so they will charge you 6% tax. That tax money is not transferred to Vermont. The only way to get any portion of it refunded to you is to contact the state that collected the tax.
