Determining the tax base on a transaction-by-transaction basis

The taxable base for deliveries of goods to which the special regime for used goods, works of art, antiques and collector's items applies will consist of the profit margin of each operation applied by the reseller, reduced by the VAT rate corresponding to said margin.

For these purposes, the profit margin will be considered the difference between the sale price and the purchase price of the good.

However, taxable resellers may waive this special regime for each specific transaction and without having to notify the Administration, and apply the general regime of the Tax.
