In theory you should be paying use taxes to California, with a credit for the New York state taxes you pay, right now. In practice that is too hard to care about, but if you try to do it with something like a car or a $10,000 piece of jewelry the state will care. Charging their local sales tax could be an excellent baby step towards the ideal. (I am not a tax attorney, nor any kind of lawyer.)
