without knowing the states this is impossible to answer because laws vary from state to state. also, there is the question of should you be collecting sales tax for out-of-state sales where that state has sales taxes. for income tax questions we could provide more information if you tell us the states, the method of shipment and whether you have any physical presence in the state, store inventory or have a salesperson n those states.
sales tax issues are beyond the scope of this forum.
