I bought a salvaged car from a person with a dealer number. I paid cash in full. He gave me the title and I went went through the process of getting it registered with the DMV. The car is now registered under my name and the DMV is sending me my new title in the mail. A few days later the person I bought the car from is asking me to send him money for the sales tax. Is this legit?
Sales tax is collected and paid by the retail seller (this is probably a universal rule). If you had bought the vehicle from a friend who isn't in the business, you would have been responsible for paying the tax. It is somewhat strange that a dealer would not know or forget this before making the sale.
