How the DGT's position has evolved
Current position
Severance payments resulting from the mutual agreement to terminate an employment relationship are income obtained in a notoriously irregular manner. To apply the 30% reduction under article 18.2 of the Personal Income Tax Law (LIRPF), it is an indispensable requirement that such income be attributed to a single tax period. Furthermore, the income must have a generation period exceeding two years.
The DGT's position has shifted from considering that mutual agreement did not allow for the exemption in certain leave plans (V1108-16) to confirming that it does indeed constitute notoriously irregular income (V0411-17). The evolution has focused on specifying the requirements for applying the reduction, such as attribution to a single tax period and a generation period exceeding two years.
