Work out the VAT due on second-hand goods, art, antiques and collectibles. Enter what you paid and what you sold the item for, and see the VAT payable on your margin, one-sixth of the difference, with no VAT due if you sell at a loss.
Optionally label the item and marketplace, enter manual selling fees and direct item costs after recoverable VAT, and see the amount left before overheads and business taxes. These costs do not reduce the margin used for VAT. This is not a VAT return or a stockbook.
