How the DGT's position has evolved

Settled doctrine High confidence 40 rulings · 2014–2026

Current position

Employment income must be attributed to the tax period in which it was due. If it is received at a different time due to circumstances not attributable to the taxpayer, supplementary self-assessments for the corresponding tax year must be filed. These returns are not subject to penalties or late payment interest.

The DGT's position has shifted from focusing on the judicial finality of the debt (2014) to applying a general rule of attribution based on when the amount was due (2021-2026). The current criterion establishes that, in the event of delays not attributable to the taxpayer, the solution is a supplementary self-assessment without penalty.
