How the DGT's position has evolved
Current position
Tax residency is determined by staying in Spain for more than 183 days or by having the core of economic activities and interests within the territory. In the event of a residency conflict, the corresponding Double Taxation Convention must be applied, prioritizing criteria such as the center of vital interests. The resident is taxed on their worldwide income, whereas the non-resident is only taxed on income from Spanish sources.
The DGT's position remains stable throughout the sequence. The rulings reiterate the criteria of stay and the core of economic activities to determine residency. No doctrinal changes are observed, but rather the constant application of domestic regulations and Double Taxation Conventions to resolve conflicts.
