I moved to CA from AZ, as well as my second hand car. I did not pay the tax at AZ when purchasing the car (may not required). When I registered the car at DMV of CA, I claimed the value of the car at a relative low price and already paid for the registration fee. The application form with my signature and the price is in my hand now, because I need to do the smog test first. So I wonder if I could raise the price next time I go to DMV and pay for the extra tax. Thanks.
