Portugal operates a progressive tax system with rates among the highest in Europe, but offers several attractive tax regimes specifically designed for expatriates and foreign residents. Cascais, located in the Lisbon metropolitan area, benefits from Portugal's favorable expatriate programs including the Non-Habitual Resident (NHR) regime and D7 visa benefits. The Portuguese tax year follows the calendar year (January-December), with annual returns typically due by June 30th. Portugal's tax system may be particularly attractive to expatriates due to its territorial approach to certain foreign income under special regimes and its extensive double taxation treaty network.
