Immigration residenceand tax residence: twostatuses, one 183-day rule

The two statuses are separate

Holding a Portugal Golden Visa does not make the holder a Portuguese tax resident; tax residence follows from spending more than 183 days in Portugal in any 12-month period, or from keeping a home there in conditions that show an intention to occupy it habitually.¹ The residence permit is issued by AIMA under the immigration law and answers the question "may this person live here"; tax residence is determined under article 16 of the personal income tax code and answers the question "does Portugal tax this person's worldwide income".²¹

An ARI holder who never crosses either tax test remains a non-resident for Portuguese income tax and is taxed in Portugal only on Portuguese-source income, if any. An ARI holder who crosses one becomes resident whether or not that was the plan.

The 183-day rule and the dwelling test

Article 16 of the Código do IRS treats a person as resident in Portugal in a given year if they were present for more than 183 days, consecutive or not, in any 12-month period beginning or ending in that year, or if, having stayed less, they had on any day of that period a dwelling in Portugal in conditions that suggest a present intention to keep and occupy it as their habitual residence.¹

Two things follow. The day count runs across a rolling 12 months, not a calendar year, so a long stay that straddles December can count. And the dwelling test is separate from the day count: a person with a home in Portugal furnished and kept for their own use can be resident on a handful of days. How that test is applied to a particular home is the first question for a tax adviser.

Where the Golden Visa's minimum stay sits

The ARI requires the holder to be in Portugal for at least seven days in the first year and fourteen days in each subsequent period.² That is a small fraction of 183 days, which is why the permit is held by many people whose tax home stays elsewhere. Meeting the immigration minimum and staying below the tax threshold are compatible.

The same low presence has a cost at the far end. The 2026 Nationality Law counts ten years of legal residence from the grant of the permit for most third-country nationals and adds integration requirements, including Portuguese at A2 level and a knowledge test.⁴ An applicant who plans to hold the permit at the minimum should ask how those requirements are expected to be met by someone who has spent a few weeks a year in the country.

The special regimes

The non-habitual resident (NHR) regime closed to new entrants at the end of 2023, and the regime that replaced it from 2024, known as IFICI, applies to specified professions and activities rather than to new residents in general.³ This site does not describe either regime. Whether an applicant's work falls within IFICI, and what it would be worth to them, is a matter for a Portuguese tax adviser with the applicant's own facts.

Where this site stops and a tax adviser starts

The questions below depend on the reader's home country and personal facts. This site names them and stops.

• US taxpayers: whether a Portuguese investment fund would be a passive foreign investment company (PFIC) for US purposes, what that means for annual reporting and tax on the units, and how US worldwide taxation interacts with any Portuguese residence.
• UK residents: whether days in Portugal or a home kept there change the outcome of the UK's statutory residence test, and how the UK-Portugal double-tax treaty allocates income and gains if both countries claim residence.
• Residents of another EU state: how the treaty between that state and Portugal resolves dual residence, and whether exit taxes apply on leaving.
• Everyone else: whether the home country has a treaty with Portugal at all, whether it taxes on residence or citizenship, and what a move of tax residence would trigger on assets held at home.
• Anyone selling the investment at year five: where the gain is taxed, and whether being resident or non-resident in Portugal at the time of sale changes the answer.
