OK. I just spoke with my lawyer and the State Board of Equalization as well as the San Jose sellers permit office. The only allowable by pass for a minor to sell at the show is to use a sellers permit number issued to his or her parents. Please note that any sales made must be reported and the tax burden is carried by the parent. If whatever is sold is not reported on your parents taxes for the next sales and use quarter they are the ones that get fined or audited. Just some safety issues to think about before anybody sneaks into daddies desk. If your 18 and you have a social security card and or a drivers license there is no reason not to run downtown and get one. Like delightful posted, they did it right there on site fast and simple. More and more conventions are being spot checked by the F.B.I. every year so don't chance getting busted. It is a simple thing to take care of, you have to do it every year if you come to the show, and it protects you from the big evil government. Thanks delightful for posting that info.
