How the DGT's position has evolved
Current position
Tax residence is determined by presence exceeding 183 days, the core of economic interests in Spain, or the habitual residence of the family. Presence is calculated through an aggregate computation of certified presence, presumed days, and sporadic absences. Any day in which there is evidence of stay in the territory is computed as a day of presence, regardless of the duration of the period.
The DGT's position remains constant regarding the criteria for residence (presence, core of interests, and family), but it has evolved towards greater technical precision in the computation of presence. The doctrine has moved from a generic definition of the 183 days to a system of integrating stages that includes certified presence and presumed days.
