How the DGT's position has evolved
Current position
Employment income must be attributed to the tax period in which it becomes due to the recipient. When income is unduly received, the tax impact corresponds to the fiscal year in which it was declared as income, and the taxpayer must file an amended tax return for the corresponding year. In cases where no amended tax return form exists for the fiscal year, the rectification procedure under Article 120.3 of the LGT (General Tax Law) must be applied.
The DGT's position remains constant regarding the attribution of income to the year it becomes due and the necessity of rectifying the period in which the income was received. No change in criterion is observed, but rather a repeated application of the obligation to rectify the tax returns of the year in which the undue income occurred.
