How the DGT's position has evolved
Current position
Employment income is imputed to the tax period in which it becomes due to the recipient. To apply the 30% reduction, the income must have a generation period exceeding two years, linked to a minimum seniority in the company and an agreement that exceeds said period. Furthermore, this reduction must not have been applied to similar income in the previous five periods, and the amount must not exceed 300,000 euros.
The DGT maintains the doctrine of imputing productivity bonuses in the fiscal year in which they become due, regardless of whether the economic effects are retroactive. This position has been consolidated regarding the application of the 30% reduction, specifying that the generation period must exceed two years in both the worker's seniority and the duration of the agreement.
Turning points
-
Establishes that enforceability arises with the positive result of the evaluation, so the imputation must be made in the period in which the agreement is adopted.
-
Specifies that for the 30% reduction, the income requires a generation period exceeding two years, requiring that both seniority and the agreement exceed that period.
