That and be organized they like when people come in with paperwork filled out and in order, but yes you have to be family (I think immediate family if Im not mistaken) to be exempt from tax, it should say that on the DMV bill of sale form. Thats how I reg’d the Harley from my father in law without paying tax. They were going to charge me tax but we put it under my name and my wifes name so they couldn’t.
