Our store does not charge sales tax at checkout. Wholesaler Outlet charges taxes based of the warehouse of product origin. So if your customer was a Florida customer and our product was shipped out of Florida then we would collect the tax and itemize it on the sales invoice that the consumer gets. You do not need to charge your customers sales tax to cover sales tax at checkout, but if your state requires "you" to collect sales tax because you are the seller then you will need to collect sales tax based on your states percentage and pay that later in the year with your taxes. Please check with your state to see if this applies to you.
