How the DGT's position has evolved
Current position
Social Security contributions derived from active retirement are attributed to self-employed economic activity as a deductible expense. The refund of contributions, whether due to excess payment or multi-activity, are classified as income from the economic activity itself. The temporal imputation of this income follows the accrual basis or the cash basis according to the taxpayer's option.
The DGT's position remains constant in classifying RETA (Special Regime for Self-Employed Workers) contributions and their refunds as elements linked to economic activity. Recent rulings have specified the nature of income from contribution refunds and the attribution of expenses in cases of active retirement, without altering the established doctrinal basis.
Turning points
-
Specifies that Social Security contributions for active retirement must be attributed to the economic activity and not to pension income.
-
Establishes that the refund of contributions due to multi-activity is income from the economic activity, following the temporal imputation rules of Corporate Tax (IS) or the cash basis.
