How the DGT's position has evolved
Current position
To access deductions for large families, maternity, or descendants with disabilities, the taxpayer must carry out self-employed or employed activity with registration in the Social Security or a mutual fund, or alternatively receive contributory benefits, welfare benefits, or pensions. The large family status is maintained as long as the certificate remains valid, even if the number of children meeting the requirements decreases. This status can be proven through the official certificate or any other means of proof admissible in Law.
The DGT's position remains constant in requiring the performance of labor activity with registration or the receipt of benefits to access deductions. It has been specified that the status of being treated as registered under the Special Agreement for caregivers does not constitute the performance of self-employed or employed activity. The doctrine confirms the validity of the large family certificate and the flexibility in the means of proving such status.
