How the DGT's position has evolved
Current position
Social Security pension arrears recognized by court ruling must be attributed to the tax period in which the resolution becomes final. The application of the 30% reduction under article 18.2 of the LIRPF (Personal Income Tax Law) is permitted when the amounts cover more than two years of generation. This application is based on the TEAC criterion to overcome the general exclusion of pensions from said reduction.
The DGT's position remains constant regarding the timing of attribution, setting it at the finality of the ruling. Regarding the 30% reduction, the doctrine has evolved from the application of general requirements to the adoption of the TEAC criterion to allow the reduction in pensions recognized judicially that cover more than two years.
Turning points
-
The application of the TEAC criterion is confirmed to allow the 30% reduction of article 18.2 of the LIRPF on pensions, despite the general regulatory exclusion, when they stem from previous periods recognized by court ruling.
