Portugal NHR and IFICI: residency days, eligibility, and how to track them
Portugal's NHR program closed to new applicants in 2024 but the successor IFICI regime offers similar benefits. Here's how 183 days, the habitual residence test, and ongoing-eligibility days work.
Portugal made the Non-Habitual Resident (NHR) regime famous: 10 years of preferential tax treatment for foreign income and a flat 20% on Portuguese-source income for high-skill workers. New NHR applications closed at the end of 2024. The successor regime, the Tax Incentive for Scientific Research and Innovation (IFICI), is narrower but still meaningful. Both programs require Portuguese tax residency, and that's where day counts come in.
Becoming a Portuguese tax resident
You become a tax resident of Portugal in any of these cases:
- You spend more than 183 days in Portugal in a 12-month period (the 12 months can span calendar years).
- You have a habitual residence in Portugal, a home available to you with the intent to use it as your habitual abode.
- You're a member of a Portuguese diplomatic mission or qualify under specific cases for crew of ships and aircraft.
The 12-month window is rolling, not the calendar year. This catches people who move mid-year and assume they're not yet residents until January.
The habitual residence test
Even below 183 days, the Portuguese tax authority (AT) can deem you a resident if you maintain a 'habitual residence' there. They look at: a long-term lease, registered utilities, family in Portugal, declared address with the tax office, and intent. Renting a Lisbon apartment for a year and visiting frequently can be enough, even if you spend only 100 days there in a calendar year.
NHR grandfathered cases
If you registered as a Portuguese resident before 31 December 2024 and qualified under the transitional rules, you may still benefit from NHR for 10 years from your registration. To keep it, you must maintain Portuguese residency. That means staying above the 183-day threshold or maintaining a habitual residence, and being able to prove it.
The IFICI successor regime
IFICI offers a 20% flat tax on qualifying Portuguese-source employment and self-employment income for 10 years, plus exemption on qualifying foreign income. Eligibility is narrower than NHR, focused on scientific research, higher education, technology, and qualified industrial activities. You still must be a Portuguese tax resident, so the day-count rules are identical.
What counts as a Portuguese day
A 'day in Portugal' for tax-residency purposes is a day where you were physically present at any time. A flight that lands and continues without immigration clearance does not count. A train trip from Madrid to Lisbon counts the day of crossing.
- Arrival day: counts.
- Departure day: counts.
- Days in Madeira and the Azores: count toward Portuguese residency.
- Days in Spain or another Schengen country: don't count for Portugal.
Tax treaty tie-breakers (when two countries claim you)
If you're a tax resident of Portugal under the 183-day rule and also a tax resident of another country, the relevant tax treaty's tie-breaker decides which country has primary taxing rights. The tests look at: permanent home, center of vital interests, habitual abode, citizenship, in that order. Day counts in both countries are foundational.
Documenting Portuguese residency
Portugal issues a Certificate of Tax Residence (CRT) to confirm your status to other tax authorities. Getting a CRT requires evidence of physical presence and ties, your day count is the foundation. The AT may also ask for Portuguese ID, NIF (tax number), bank account statements, utility bills, and lease agreements.
If you claim NHR or IFICI but your home country challenges your departure, you'll need to prove Portuguese residency, sever ties to the old country, and survive a treaty tie-breaker. Don't lose this fight on day-count records you should have kept.
Track Portuguese days from day one
Tax Days tracks your Portuguese days against the 183-in-12-months rule, plus your old country's threshold for departing-resident audits. Configure both in 30 seconds and the app updates as you log trips.
Frequently asked questions
Is Portugal's NHR program still open to new applicants?
No, new NHR applications closed at the end of 2024. If you registered as a Portuguese resident before 31 December 2024 and qualified under the transitional rules, you may still benefit from NHR for 10 years from your registration, provided you maintain Portuguese residency. The successor regime is IFICI, the Tax Incentive for Scientific Research and Innovation.
How many days do you need to spend in Portugal to become a tax resident?
You generally become a Portuguese tax resident by spending more than 183 days in Portugal in a 12-month period. Importantly, that 12-month window is rolling rather than tied to the calendar year, which catches people who move mid-year and assume they are not residents until January.
Can I be a Portuguese tax resident with fewer than 183 days?
Yes, generally. Even below 183 days, the Portuguese tax authority can deem you a resident if you maintain a habitual residence there, looking at factors like a long-term lease, registered utilities, family in Portugal, a declared address with the tax office, and intent. Renting a Lisbon apartment for a year and visiting frequently can be enough even at around 100 days.
Do days in Madeira or the Azores count toward Portuguese tax residency?
Yes, days in Madeira and the Azores count toward Portuguese residency, and both arrival and departure days count. A flight that lands and continues without immigration clearance generally does not count, and days spent in Spain or another Schengen country do not count for Portugal.
What is Portugal's IFICI regime?
IFICI offers a 20% flat tax on qualifying Portuguese-source employment and self-employment income for 10 years, plus an exemption on qualifying foreign income. Eligibility is narrower than NHR, focused on scientific research, higher education, technology, and qualified industrial activities, and you still must be a Portuguese tax resident under the same day-count rules.
