How the DGT's position has evolved
Current position
Tax residence is determined by staying more than 183 days in Spanish territory or by having the core of economic activities or interests located in the country. In the event of a residence conflict with another State, the rules of the corresponding Double Taxation Convention shall apply. Residence is a necessary condition for applying specific exemptions, such as the one for the primary residence for those over 65 years of age.
The DGT's position remains constant in the application of the criteria of permanence and the core of economic interests. No changes are observed in the interpretation of the rule, with rulings being limited to applying the criterion to specific cases or resolving conflicts through international conventions. The doctrine has been uniform since 2014.
