How the DGT's position has evolved
Current position
Economic benefits derived from a collective agreement, such as grants, loyalty bonuses, or compensatory payments, constitute employment income subject to IRPF (Personal Income Tax). To apply the 30% reduction under article 18.2 of the LIRPF (Law on Personal Income Tax), the dual condition must be met that the income is linked to a seniority of more than two years and that the agreement also exceeds said period. Salary increases are imputed to the tax period in which they become due.
The DGT maintains a consistent position in classifying collective agreement benefits as employment income. It has specified the application of the 30% reduction by requiring that both seniority and the agreement exceed two years, even in cases of adaptation of previous agreements. No change in criterion is observed, but rather a repeated application of the regulations to different scenarios.
Turning points
-
Establishes that in adaptations of agreements where remuneration is adjusted to the socio-labor reality without increasing the global amount, the condition of a generation period exceeding two years is met.
-
Confirms that the adaptation of a concept already existing in previous agreements allows for the consideration that there is a generation period exceeding two years for the 30% reduction.
