How the DGT's position has evolved
Current position
The modification of the tax base due to definitive non-payment or contract rescission allows for the rectification of passed-on quotas. This rectification must be carried out within a period of four years from the occurrence of the circumstance of the debt's extinction. The taxpayer may opt for the self-assessment rectification procedure or regularize through subsequent tax returns.
The DGT's position remains constant regarding the possibility of rectifying quotas due to non-payment or rescission, but it has specified the requirements for doing so. It has emphasized the need to pursue collection through judicial claim or notary requirement to validate the reduction of the tax base for uncollectible credits. Likewise, it has clarified the calculation of the statute of limitations periods for rectification.
