How the DGT's position has evolved
Current position
The right to deduct amounts incurred may be exercised as long as the four-year expiration period from the birth of the right has not elapsed. To this end, it is necessary to possess the legal supporting documents, such as the original invoice, and to comply with the requirements of the IVA (Value Added Tax) Law. In the event of inspection proceedings, the amounts must be duly recorded in the accounting books.
The DGT's position remains constant regarding the application of the four-year expiration period for the exercise of the right to deduction. The rulings confirm the need to possess supporting documentation and compliance with legal requirements. No changes are observed in the interpretation of the period or the substantive requirements throughout the sequence.
