How the DGT's position has evolved
Current position
Tax residence is determined by staying in Spain for more than 183 days or by having the core of economic activities or interests in Spanish territory. For the calculation of the period of stay, sporadic absences are included, unless tax residence in another country is proven. In the event of a conflict of residence, the rules of Double Taxation Treaties must be applied.
The DGT's position on determining tax residence through the period of stay criterion remains constant throughout the rulings. The resolutions of 2016, 2017, and 2021 reiterate the same requirements of the 183 days or the core of economic interests. No changes are observed in the interpretation of the rule, except for the explicit mention of conflict resolution through international treaties.
