How the DGT's position has evolved
Current position
The rectification of deductions must be carried out in the period in which the corrective invoice is received when the discount modifies the tax base. If the rectification increases the tax base, the taxable person may opt to carry it out in the period of receipt or in subsequent periods, respecting the four-year period. In cases of self-invoicing for advance payments, the rectification must be applied in the periods where the original accrual occurred.
The DGT's position remains constant regarding the obligation to rectify deductions in the event of changes to the tax base or the destination of the goods. A systematic application of the obligation to rectify is observed when the foreseeable destination of the goods changes or when subsequent discounts occur. The doctrine has focused on specifying the timeframes and rectification mechanisms according to the type of operation.
