How the DGT's position has evolved
Current position
Taxing authority over salaries depends on the physical location where the employment is exercised, with the State where the work is performed prevailing according to the applicable conventions. In cases of public pensions, taxation may shift to the State of residence if the beneficiary holds the nationality of said State. For the exemption regarding international assignments, it is imperative that the work be physically performed outside of Spain for a non-resident entity in a country with an information exchange agreement.
The DGT's position remains constant in applying the rule of physical territoriality of work to determine taxing authority. No doctrinal changes are observed, but rather the application of specific criteria depending on the nature of the income (salaries, pensions, or assignments) and the applicable convention. The doctrine is consistent in that the place where the activity is exercised determines the tax.
Turning points
-
Specifies that for income to be taxed exclusively in the State of origin, three simultaneous conditions must be met: a stay of less than 183 days, a non-resident payer, and the absence of a permanent establishment in the State of residence.
-
Establishes the nationality exception in public pensions, allowing the State of residence to tax the income if the beneficiary is a resident and national of said State.
