How the DGT's position has evolved
Current position
Lump-sum compensation is applied to the sale price of products, without being affected by the application of super-reduced rates or the 0% rate. The right to deduction arises only when the compensations have been effectively satisfied, which includes the effectiveness of promissory notes. In case of errors, tax amounts may be adjusted through corrective invoices within four years of the accrual, reintegrating unduly received amounts through form 309.
The DGT's position remains stable regarding the nature of the compensation, but it has specified the requirements for enforceability for the deduction. It has been clarified that the right arises with effective payment and not with the issuance of payment documents. Likewise, the rectification mechanisms in the event of undue collections have been detailed.
