How the DGT's position has evolved
Current position
The disability deduction requires that the beneficiary does not exceed 8,000 euros in income and does not file a tax return with income exceeding 1,800 euros. The taxpayer must carry out self-employed or employed activity, or receive pensions or unemployment benefits. In the case of descendants, the status of de facto guardian does not allow for the application of personal allowances or the deduction, being limited to children, grandchildren, great-grandchildren, or those assimilated through guardianship or foster care.
The DGT's position remains constant regarding income limits and the requirement for the taxpayer to be active. A doctrinal precision is observed regarding the exclusion of de facto guardians from accessing tax benefits. The criterion has remained stable in the application of cohabitation and economic dependency requirements.
