How the DGT's position has evolved
Current position
The restitution of amounts received by error has no impact on the IRPF (Personal Income Tax) of the tax year in which the refund is made. If the amounts were previously included as employment income, the impact must be managed by amending the tax return of the year in which they were declared as income. If they were not included as income, the refund has no tax impact as it is a consumption-based transaction.
The DGT's position is constant regarding the timing of the tax impact, stating that the effect must fall on the tax year in which the income was received and not on the year of the refund. The rulings confirm that if the amount was never declared as income, its return does not constitute an operation subject to IRPF.
Turning points
-
Establishes that the impact of unduly deducted amounts must take place in the settlement of the tax year in which they were included as an expense through a supplementary tax return.
-
Specifies that if the amounts have not yet been declared, no action is required regarding IRPF because they do not have the nature of income.
