If you're charging sales tax on your items, you'll need to apply the correct state sales tax to the products you publish through Printful. Before you add your first product head to Site Preferences in eBay. Under Payment from buyers, you`ll see the Use sales tax table. Fill out this table before adding products, because all of the products that you`re going to list will have sales tax charged according to this sales tax table.
We strongly recommend you consult with a tax specialist on your specific situation because depending on where you’re located you might have different tax obligations you need to meet.
