How the DGT's position has evolved
Current position
Contributions to social security provision systems must comply with the limits of the Personal Income Tax Law (LIRPF) to be deductible from the taxable base. Any excess over the maximum legal limits cannot be deducted in the current tax year or in the following five years. For the special regime for persons with disabilities, it is mandatory to opt for the special financial regime before making contributions in order to apply the corresponding tax benefits.
The DGT's position remains constant regarding the application of LIRPF limits and the prohibition of carrying forward excess contributions to future tax years. There is an insistence on the need to meet prior requirements, such as opting for the special financial regime in cases of disability, to access specific benefits. There are no changes in criterion, but rather a reiteration of the current regulations.
Turning points
-
Clarifies that the excess over the maximum contribution limits cannot be subject to reduction in the following five tax years, limiting the benefit only to excesses due to insufficient taxable base.
-
Establishes that the option for the special financial regime must be made prior to the contributions in order to apply the special tax regime for social security provision.
