IFICI provides narrower research and innovation tax relief

IFICI can apply a 20% special rate to qualifying Portuguese-source Category A or B income for ten years and generally exempt qualifying foreign-source income other than pensions, subject to exceptions including listed low-tax jurisdictions. Eligibility requires no Portuguese tax residence in the previous five years, qualifying work and certification by the responsible body; it is not a general replacement tax holiday for retirees or remote workers.
