How the DGT's position has evolved

Settled doctrine High confidence 10 rulings · 2014–2024

Current position

The choice between joint or individual taxation is irrevocable once the tax return filing period has ended. Changes are only permitted in the event of substantial modifications to circumstances not attributable to the taxpayer. In the case of energy renovation deductions, quantitative limits are applied individually for each owner or remain unchanged in joint taxation.

The DGT's position remains constant regarding the irrevocability of the taxation option after the regulatory deadline. The doctrine has moved from a mere confirmation of the impossibility of rectification to specifying that an error in the calculation of the tax benefit does not constitute a cause for modification. Likewise, clarifications have been integrated regarding the application of limits in specific deductions for individual or joint holders.
