Question

Answer 1

If you sell an item at a profit you are required to report that profit on your state and federal income tax income tax.  Selling it in another state could have implications of state income tax in the state of the sale.  If it does you would report the sale in both states and take a deduction in California for the tax paid in another state.

Answer 2

Income tax, yes.
