Polish tax residence: the 183-day rule and centre of interests
Short answer: You are a Polish tax resident if you stay in Poland more than 183 days in a calendar year or your centre of personal or economic interests is in Poland.
Whether you are a Polish tax resident decides what Poland can tax. If you are a resident, you report your income from all over the world in Poland. If you are not, you only pay Polish tax on income earned in Poland. The rules are in article 3 of the Personal Income Tax Act (PIT). This guide is based on the Ministry of Finance's official tax explanations of 29 April 2021 on tax residence, and on the government's information page, which was marked as reflecting the law as of 18 May 2026. It is general information, not tax advice. For a complicated case, ask a tax adviser or the tax office.
The two tests
According to the Ministry of Finance, a person has a place of residence in Poland for tax purposes if at least one of these is true:
1. the person has the centre of personal or economic interests (the "centre of vital interests") in Poland, or
2. the person stays in Poland for more than 183 days in the tax year.
The explanations stress that the word "or" matters. Each test is assessed on its own, and meeting one is enough to make you a Polish tax resident.
Unlimited and limited tax liability
If Poland is your place of residence, you have "unlimited tax liability". You must report in Poland the income from all sources, in Poland and abroad. The explanations add that income earned abroad is not taxed twice, because double-taxation rules prevent it.
If Poland is not your place of residence, you have "limited tax liability" and pay Polish tax only on income earned in Poland. The ministry gives an example of a programmer whose tax residence is in the Netherlands, who works in Poland for five months for a Polish employer and then goes back. She reports in Poland only the salary earned in Poland and does not show her other foreign income.
The 183-day test
The ministry explains that the day-count criterion is met after you pass 183 days of presence in Poland in a calendar year. The calendar year is the basic tax period for individuals. If you do not pass that number of days, the first test fails, and the decision depends on the second test, the centre of vital interests.
Three details are important:
- The stay does not need to be continuous. For a longer period of non-continuous stays, you check whether the number of days passed 183 in any calendar year.
- Days are counted by the method of "days of physical presence". All days spent in Poland count, including the day of arrival and the day of departure.
- Any part of a day, even a very short one, counts as a day of presence. A full day spent outside Poland does not count.
The centre of vital interests
The second test has two parts, personal and economic. Either is enough.
Personal interests are your close personal ties: family, friends, social, cultural, sport or political activity. The explanations say that in practice the most important factor is the presence in Poland of a spouse, a partner or minor children. Moving abroad with your whole family will in most cases move the centre of personal interests there. Going abroad to work while your spouse and children stay in Poland will usually keep it in Poland. For a single person, the ministry says to look at which country the person keeps a household in and where he or she takes part in social and cultural life.
Economic interests are your close economic ties. The ministry lists the place where you work, your main sources of income, investments, real estate and movable property, loans, bank accounts and the place from which you manage your assets.
The explanations give examples. A person who is still registered at the parents' address but now lives with a partner in the UK, with daily life, doctor and friends there, has moved the personal centre of interests to the UK. A person with a car workshop in Poland as the only source of income, a house and a Polish bank account keeps the economic centre in Poland, even if he spends part of the year in France.
How to show you are not a Polish resident
For people who are leaving Poland, the government's returns portal lists the circumstances that are considered first when you want to show you do not live in Poland:
- your closest family, for example a spouse and children, live abroad,
- you have a home at your disposal in the other country, rented or owned,
- other circumstances, such as an open-ended employment contract, an open-ended rental contract or contracts with utility providers,
- you own movable or immovable property abroad, such as a car or a house,
- you hold a certificate of tax residence from the other country.
When two countries both say you are a resident
Poland has double tax treaties with most countries that Poles emigrated to, including all EU states and the European Economic Area states with the exception of Liechtenstein. If two countries both treat you as a resident, the treaty's tie-breaker rules decide, usually in article 4, paragraph 2. As a rule, you are considered a resident only of the state where you have a permanent home. If you have a permanent home in both, the next test is the centre of vital interests, and so on. Read the treaty between Poland and your country.
What this means for a newcomer
- If you arrive in Poland in the middle of the year, count your days of presence. After 183 days in a calendar year you become a resident for that year.
- You can be a resident before that, if your family lives with you in Poland, you rent a flat, work here and keep your bank accounts here.
- A resident files a PIT return for worldwide income. Our guide to the annual PIT return explains the practical side: Polish annual tax return for expats.
- Keep records of your travel days and a certificate of tax residence if you need to show it to a tax office.
Frequently asked questions
Do I become a Polish tax resident after 183 days?
Yes, if you stay in Poland for more than 183 days in a tax (calendar) year. You can also be a resident earlier if your centre of vital interests is in Poland.
Do the 183 days have to be in a row?
No. The ministry says the stay does not have to be continuous. You check the total number of days in a calendar year.
Does a day of arrival count?
Yes. The day of arrival and the day of departure count, and so does any part of a day spent in Poland.
Is foreign income taxed in Poland?
If you are a Polish tax resident, you must report it in Poland, but double-taxation rules prevent the same income from being taxed twice. A non-resident reports only income earned in Poland.
What if two countries both treat me as a resident?
The tax treaty between the countries decides, using tie-breaker rules, usually in article 4, paragraph 2.
