How the DGT's position has evolved
Current position
The economic-administrative claims regulations of the LGT (General Tax Law) are not applicable to local entities, which must be governed by local tax regulations. In the case of local taxes without a specialized body, only an appeal for reversal (recurso de reposición) is admissible against acts of application and effectiveness. For other taxes, the refund of undue payments to the Social Security must be imputed in the fiscal years in which they were included as an expense through rectification or a supplementary self-assessment.
The DGT's position does not show a doctrinal evolution regarding the concept of the refund of undue payments; rather, the rulings address different procedural and accounting imputation aspects. The focus has shifted from dealing with the rectification mechanics in IVA (VAT) and IS (Corporate Income Tax) to defining statute of limitations periods, the effects of Social Security, and regulatory competence in the local sphere.
Turning points
-
Specifies the calculation of the four-year statute of limitations period, indicating that it begins on the day following the payment or the expiration of the self-assessment deadline.
-
Establishes that the refund of Social Security payments requires rectification or a supplementary self-assessment in the fiscal years where they were accounted for as an expense.
