How the DGT's position has evolved
Current position
The Autonomous Community competent for Inheritance Tax (ISD) is the one corresponding to the habitual residence of the deceased. This residence is determined by the territory where the greatest number of days was spent in the five-year period prior to the accrual. The accreditation of said stay is a matter of fact that must be proven with valid means under Law.
The DGT's position remains constant in determining regional competence based on the habitual residence of the deceased. Recent rulings reiterate the criterion of the majority of days spent in the five-year period prior to the accrual. No doctrinal changes are observed, but rather a reaffirmation of the method for determining residence.
