How to become a tax resident of Portugal in 2026
More than 183 days in any 12 months or a permanent home in the country, residency from the day of arrival and a 20% rate for qualified professionals: a guide for foreigners.
In short: you become a tax resident of Portugal if you spend more than 183 days in the country in any 12 months that start or end in the tax year, or keep a home in Portugal as your permanent one. The status can start on the day of arrival. A resident pays tax on worldwide income.

Portugal counts days not by calendar year but in a rolling window: any 12 months that touch the tax year. So the familiar plan of half a year here and half a year there across two years often makes a person resident without intending it.
There is also a second route with no day count: a permanent home in the country. And for people moving to work in science, technology and export industries Portugal offers a 20% rate for 10 years. Below: how days are counted, how to become resident step by step, where to get the certificate and what citizens of particular countries should bear in mind.

How days are counted in Portugal
The first test is days. You are resident if you spend more than 183 days in Portugal, consecutive or not, in any 12-month period that starts or ends in the year in question. Every day on which you stay overnight in the country counts.
The second test is a home. Even with fewer days you are resident if on any day of those 12 months you had a home in Portugal in conditions showing an intention to occupy it as your permanent residence: a long lease in your name, a Portuguese address in your tax record, family and children's school in the country. Status is assessed not for the whole year but from the first day of stay: for the resident part of the year you declare worldwide income, for the rest only Portuguese income.
| Situation | How it counts |
|---|---|
| More than 183 days in any 12 months that start or end in the year | resident for that year |
| 100 days at the end of one year and 100 at the start of the next | 200 days in one window: resident |
| Fewer than 183 days but a home kept as your permanent one | resident |
| Move on 1 September | resident from 1 September if the conditions are met; non-resident before that |
| Leaving Portugal for good | residency ends on the last day in the country |
| A holiday flat with no intention to live there permanently | does not by itself make you resident |
You will have to prove the date residency began: tickets, a lease, address registration. You can count days by travel dates in our tax residency calculator.
How to become a tax resident of Portugal: step by step
Tax status in Portugal arises from the facts, but you have to formalise it yourself: while your tax record shows a foreign address, the authority treats you as non-resident.
- Get a tax number. The tax authority issues it on your passport. Non-residents from outside the EU need a tax representative or must sign up for electronic notifications.
- Secure the right to live in the country. Non-EU citizens need a visa and a residence permit: for passive income, remote work, employment, business or investment. EU citizens register with the municipality.
- Rent or buy a home. A long-term lease or title is the main evidence both for days and for a permanent home.
- Change your address with the tax authority to a Portuguese one. From that moment the authority treats you as resident. The change must be reported within 60 days.
- Check eligibility for the 20% rate. If you were not a Portuguese resident in the previous 5 years and work in a qualified activity, the application is filed by 15 January of the year after the move.
- File a tax return. The annual return is filed from April to June of the following year. In the year of the move it splits income into the periods before and after residency began.
- Request the residency certificate. It is generated online in your account on the tax portal, free of charge.
- Close residency in your previous country. Report the move where required and do not reach your previous country's day threshold.
Tax residency certificate and double tax treaties
The tax residency certificate is issued by the Portuguese tax authority. You request it online in your account on the tax portal, and it is generated free of charge and at once if your record shows a Portuguese address and the data are consistent. It states the year for which the status is confirmed and, if needed, the treaty it is issued for.
Portugal has about 80 double tax treaties, including with Ukraine, Moldova, Georgia, Estonia, Latvia, Lithuania, Germany, the UK, the US and Brazil. There are no treaties in force with Kazakhstan, Armenia, Azerbaijan, Belarus, Kyrgyzstan or Uzbekistan: income from those countries is taxed at full domestic rates on both sides, and Portugal credits foreign tax up to its own.
The treaty with Russia formally remains in force, but in August 2023 Russia suspended its main articles: payments from Russia are subject to withholding at Russian domestic rates.
What changes in your taxes once you are resident
A Portuguese resident pays income tax on worldwide income on a scale from 12.5% to 48%, plus an additional 2.5-5% surcharge on very high incomes. Dividends, interest and capital gains are taxed at 28% and rental income at 25%. A non-resident pays only on Portuguese income: 25% on salary and pensions.
The former regime for new residents is closed to those who moved after 2024. Its replacement is a 20% rate on salary and self-employment income from qualified activities for 10 consecutive years: university teaching and science, work in certified start-ups, in technology centres, in export industries and in companies with investment incentives. Foreign dividends, interest, rent and capital gains are exempt under the regime; pensions are not. Below are the resident's rates by type of income.
| Income | Tax for a resident of Portugal |
|---|---|
| Foreign income | always taxed |
| Dividends | 28% |
| Interest | 28% |
| Capital gains | 28% |
| Property sales | scale, half the gain |
| Crypto | 0% or 28% |
Crypto held over a year is tax-free.

How to avoid becoming tax resident in two countries
The rolling 12-month window and a home as a separate test make Portugal a country where it is easy to become resident by accident. If you live between two countries, count days not by calendar year but over any 12 consecutive months.
When both countries treat you as resident, the treaty settles it: first where your permanent home is, then your centre of vital interests, then where you habitually live, then citizenship. Without a treaty each country applies its own rules and only a tax credit remains.
The practical rule: document the date of your move, leave your previous country's residency under its rules and do not keep a home there that looks permanent.
Restrictions for certain nationalities
Portugal's tax residency rules are the same for everyone, but citizenship affects the right to live in the country and the treaties.
EU citizens live and work in Portugal freely and only register with the municipality. Non-EU citizens need a residence permit, and the first step is a visa at a consulate. Citizens of Portuguese-speaking countries have a simplified route to a residence permit.
There is no separate ban on residence permits for Russian citizens, but the reduced treaty rates with Russia do not apply since Russia suspended the main articles of the treaty in 2023.
US citizens are taxed on citizenship wherever they live: the Portugal-US treaty is in force, and Portuguese tax is credited against US tax under its rules.
Portuguese tax residency means a rolling 12 months, a home and a certificate from the tax authority
The law does not stop you from becoming a Portuguese resident on your own. But mistakes cost more than fees: days counted by calendar year rather than in the rolling window; a foreign address left in your tax record, so the authority treats you as non-resident; the 20% rate application not filed by 15 January and the relief lost for all 10 years. Murblz support removes these risks: Murblz specialists count the days, arrange the tax number, residence permit and address, check eligibility for the 20% rate, obtain the residency certificate and plan your exit from the previous country. We guarantee professional work and a transparent process, and in most cases a result on the first filing.
The cost of support depends on the residence route and your previous country; a manager will calculate it in the chat.
