How the DGT's position has evolved
Current position
Tax residence is determined by staying for more than 183 days or by the core of economic activities and interests in Spain. In the event of a dual residence conflict, the applicable Convention must be applied, prioritizing the center of vital interests (closest personal and economic relationships). If this criterion does not resolve the conflict, recourse is made to habitual residence and, finally, to nationality.
The DGT's position has remained constant over time. Consultations repeatedly confirm that, in cases of residence conflicts, the center of vital interests is the fundamental tie-breaking criterion after permanent housing. No changes in the interpretation of this concept have been observed throughout the sequence.
