If I'm registered to collect sales tax in a specific state, must I collect on all items I sell? What if I paid sales tax to the merchant on the item I am now selling? And if I purchase an item from an out of state merchant, which they won't have to charge me sales tax, must I charge sales tax when I resell that item? Tia
Sales Tax rules vary by state/jurisdiction but in general if you are registered to collect Sales Tax in a specific state, you must collect the tax on all products you sell in the state, that are subject to Sales Tax.
Again, the rules vary by state but in general you can claim a credit on your sales tax return for sales taxes you paid out on goods you purchased for resale.
Yes, you have to collect sales tax on all goods you sell in a state where you are registered as a sales tax vendor, regardless of where you purchased the merchandise.
