Tax residency
When Portugal taxes you
A visa lets you stay. It does not decide who taxes you. In Portugal that turns on a day count of about 183 days and the ties you keep, and it is the line that quietly reshapes what you take home.
When you become tax resident
Resident if more than 183 days in any 12-month period, OR maintaining a habitual home (dwelling kept as habitual residence) in Portugal on 31 Dec Special regime: NHR closed to new entrants; replaced by IFICI (NHR 2.0), a 20% flat rate for qualifying research/innovation/high-value activity income, requiring no PT tax residency in prior 5 years.
Also a habitual home kept in Portugal on 31 Dec.
How your income is taxed
Progressive PIT up to 48% top rate (plus a solidarity surcharge of 2.5-5% on high incomes); IFICI regime caps qualifying income at a 20% flat rate
The trap below the day count
Staying under 183 days does not make you safe. A permanent home available to you, a partner or children living in Portugal, or your centre of vital interests can create residence well below the count. And where two countries both claim you in the same year, a tax treaty tie-breaker decides, on your permanent home first, then your centre of vital interests, then where you habitually live. This is the part worth taking to a specialist.
Count your days against the threshold
The tracker counts the days you spend in each country and shows which cross their tax-residency line, Portugal included.
