How the DGT's position has evolved
Current position
Contractual termination and the definitive non-payment of the debt that extinguishes the credit are causes for modification of the tax base. The taxpayer must rectify the charged tax liabilities provided that the invoice was issued within one year from the accrual. The four-year period to carry out the rectification is computed from the occurrence of the circumstances that give rise to the modification.
The DGT's position remains stable regarding the mechanics of rectification in the event of changes to the tax base. The analyzed rulings do not show a change in doctrine, but rather apply the concept of rectification to various scenarios such as price alterations, judicial rulings, or non-payments. The evolution is a constant application of Article 80.Two of Law 37/1992 to different operational scenarios.
