I think you've misunderstood. I'm saying it's the same item and depending on where I purchased I may or may not be setup to purchase items tax exempt for resale. So I've paid tax on some but not all I have in inventory.  When I pay sales tax to the state I would think I'm not liable for sales tax I've already paid on a resale item.  Therefore I need to remove the portion I've already paid.  The only thing I can think to do is track this on my own and remove it manually when I submit sales tax payments to the state unless QuickBooks can actually tell the difference.  I do not want to create additional items in QuickBooks each time there's a change in price or sales tax.
