How the DGT's position has evolved
Current position
Contributions to social welfare mutual societies acting as an alternative to the RETA (Special Regime for Self-Employed Workers) are deductible as business expenses to the extent that they cover contingencies handled by the Social Security. This deductibility is limited to the maximum contribution for common contingencies established for the special regime for self-employed workers in each fiscal year. Any excess over said limit may be subject to a reduction in the taxable base if it meets the legal requirements.
The DGT's position has remained constant since 2018. The criterion establishes that the deductibility of contributions to mutual societies is conditional upon them acting as an alternative to the RETA and is limited to the maximum contribution for common contingencies. Subsequent rulings have reiterated this treatment without substantial variations.
