Tax profile

What makes you a tax resident — and how hard it is to stop being one.

• Presence in Portugal for more than 183 days, consecutive or not, in any 12‑month period starting or ending in the calendar year concerned
• Having in Portugal, on any day of the relevant 12‑month period, a home under circumstances implying the intention to keep and occupy it as a permanent/habitual residence, even if present for fewer than 183 days
• Being, on 31 December, a crew member of a ship or aircraft operated by an entity resident in Portugal
• Performing public functions or commissions abroad in the service of the Portuguese State
• Being a Portuguese national who moves tax residence to a country/territory/region with a clearly more favourable tax regime on Portugal’s official list, in which case they are still treated as Portuguese tax resident in the year of the move and the four subsequent years unless they prove the move is for a valid reason

Ceasing residency is in principle from the last day of stay, but Portuguese nationals moving to listed low‑tax jurisdictions can remain deemed residents for up to five years unless they prove valid reasons for the move, which makes cleanly leaving somewhat harder in those cases.
