Portugal has been one of Europe's most popular destinations for wealthy expats and digital nomads, largely due to the NHR (Non-Habitual Resident) tax regime — which offered 10 years of highly favourable tax treatment. With the NHR programme closed to new applicants in January 2024 (replaced by IFICI/NHR 2.0), and a significant international community that is now considering leaving Portugal, the departure rules are increasingly relevant. Portugal's departure is administratively clean — no exit tax, straightforward AT deregistration — but the NHR exit, Golden Visa residency rules, and Portuguese property CGT as a non-resident require specific attention.
Portugal-to-USA migration includes US citizens who moved to Portugal under NHR (returning after NHR years), European expats transiting through Portugal, and Portuguese nationals. Key PT-US planning points:
NHR and US citizenship: US citizens who moved to Portugal for NHR must understand that the USA taxes US citizens on worldwide income regardless of the NHR regime's Portuguese exemptions. The US does not recognise Portugal's NHR exemptions on foreign income — those US citizens on NHR were still required to file US Form 1040 and report all worldwide income. The NHR saved Portuguese tax, not US tax. On leaving Portugal: file a final Portuguese IRS return; continue US reporting as normal.
Portugal-USA DTA: A Portugal-USA Double Taxation Agreement was signed in 1994 but has not yet entered into force as of early 2026 (subject to ratification). Check the current status — if in force, it changes withholding rates on Portuguese dividends, interest, and pensions. In the absence of a treaty, standard Portuguese non-resident rates apply and US residents claim FTC on US Form 1116.
Portuguese pension abroad: The Portuguese Segurança Social (Social Security) manages the pensão de velhice (old age pension). Payable internationally via Centros Distritais da Segurança Social or IGFSS. Portugal has totalization agreements with the USA (via a separate Portuguese-US agreement) and EU countries. Check your Portuguese contribution record via Segurança Social Direta (seg-social.pt) before departure.
