How the DGT's position has evolved

Refined position High confidence 62 rulings · 2016–2026

Current position

The deduction requires performing self-employed or employed activity with registration in the Social Security system, or receiving contributory or welfare unemployment benefits or pensions. The large family status must be proven according to Law 40/2003 by any means of proof admissible in Law. The benefit applies proportionally to the months in which the requirements of activity and large family status concur simultaneously.

The DGT's position remains constant regarding the requirements for activity and benefits. A relevant change is observed in the way large family status is proven, moving from requiring the application date of the certificate to allowing any means of proof admissible in Law. The application of the deduction is confirmed as proportional to the period during which the requirements concur.

Turning points

  1. V1257-21

    It established that the effects of large family status take effect from the date the application for the official certificate is submitted.

  2. V0943-22

    It modifies the previous criterion by allowing large family status to be proven by any means of proof admissible in Law, not exclusively through the official certificate.
