Portugal tax residency rules
Threshold: 183 days · Day Count · Calendar year (Jan 1 – Dec 31)
Portugal's NHR regime closed to new applicants in 2024 but the IFICI successor and the standard 183-day residency rule remain. Portugal taxes residents on worldwide income; non-residents only on Portuguese-source income. Tax residency triggers at 183 days in any 12-month period (rolling) OR maintenance of a habitual residence.
- Rolling 12-month 183-day rule, not calendar-year only.
- Habitual residence (long-term lease + utilities + intent) can trigger residency under 183 days.
- Certificate of Tax Residence (CRT) required for treaty-partner recognition.
