How the DGT's position has evolved
Current position
Taxing power over profits from exploitation in international traffic rests with the State of residence of the company. In the case of remuneration for employment on board, taxation depends on the application of Double Taxation Conventions, which usually attribute taxing power to the State of effective management. If the international traffic requirements of the Convention are not met, the general rules for taxation on activities carried out in Spanish territory apply.
The DGT's position remains constant in the application of Double Taxation Conventions to determine taxing power in international traffic. Consultations show a systematic application of the place of effective management for employment income and the residence of the company for profits from exploitation. No doctrinal changes are observed, but rather the application of specific criteria according to the content of each Convention.
