How the DGT's position has evolved
Current position
The cancellation of a debt through an insurance provision or dation in payment generates a capital gain for the amount of the debt amortized, which must be included in the general taxable base. In the case of subsidies for debt payment, these are considered income from economic activity, and their temporal imputation follows the accounting rules of the fiscal year in which the debt is cancelled. The novation or subrogation of loans does not extinguish the deduction for the primary residence, allowing for the proportional deductibility of the new interest.
The DGT's position remains constant in classifying debt cancellation as a change in assets that generates gains in the general base. A diversification of scenarios is observed, ranging from dation in payment and insurance to the management of subsidies and the continuity of deductions in novation operations. There are no changes in criterion, but rather an application of the same concept to different cancellation vehicles.
Turning points
-
Specifies that dation in payment maintains its exempt nature if carried out in favor of a third party who accepts it as extinguishing the obligation.
-
Establishes that novation or subrogation does not exhaust the deduction for the primary residence, allowing for the deductibility of new interest on a proportional basis.
