How the DGT's position has evolved
Current position
To apply the minimums for ascendants or descendants, the relative must not exceed an annual income limit of 8,000 euros (excluding exempt income) nor file a tax return with income exceeding 1,800 euros. In the absence of physical cohabitation, economic dependency is admitted as an equivalent to meet the cohabitation requirement. The application of the minimum for the relative's disability is subject to the prior application of the minimum for ascendants or descendants.
The DGT's position has evolved from a control based solely on the 8,000 euro income limit towards a stricter control that includes a second threshold of 1,800 euros for those who file a tax return. Likewise, the assimilation of cohabitation with economic dependency has been specified to facilitate the application of the minimums.
Turning points
-
Introduces the additional requirement that the descendant must not file a tax return with income exceeding 1,800 euros to access the minimum.
-
Reinforces the application of the 1,800 euro limit for ascendants and specifies that in joint tax returns, individualized income must be verified.
