When Do You Become a Polish Tax Resident?
March 13, 2026
Last updated: 13 March 2026
If you moved to Poland, you must determine from which moment you start paying taxes in Poland. In other words, you must determine when you become a Polish tax resident and for which year Polish taxation begins.
If you obtain the status of a Polish tax resident in a given tax year, you must declare and pay tax in Poland for that year on all sources of income, including income earned abroad.
In practice, the answer usually depends on two statutory tests used by the Polish tax system: the 183 day rule and the centre of personal or economic interests test. If you meet either of them in a given calendar year, you are treated as a Polish tax resident for that entire tax year.
What is Polish tax residency
A person becomes a Polish tax resident if they stay in Poland for more than 183 days in a calendar year or if their centre of personal or economic interests is located in Poland. Once tax residency arises, Poland taxes the person’s worldwide income for that tax year.
The 183 day rule in Poland
Under Polish tax law, a person becomes a Polish tax resident if they stay in Poland for more than 183 days in a calendar year. This is one of the two statutory residency tests.
The rule is based on the calendar year, not on any rolling twelve month period. Once the 183 day threshold is exceeded in a given year, Polish tax residency for that year must be taken into account.
- the counting is based on the same calendar tax year
- it is not a rolling twelve month test
- formal registration or payroll structure does not override the day count
- once the threshold is exceeded, Polish tax residency must be considered for that year
This test is important because many foreigners wrongly assume that tax residence depends only on formal registration, visa status or foreign payroll. From the Polish perspective, the day count itself can be decisive.
Centre of personal or economic interests
A person may also become a Polish tax resident if their centre of personal or economic interests is located in Poland. This is a separate statutory test. It does not require more than 183 days in Poland.
Polish tax authorities analyse actual factual links with Poland. Relevant factors typically include:
- where the person works
- where the spouse or children live
- where the person maintains a home
- where the main bank accounts or investments are located
- where the person’s personal and economic life is actually centred
In practice, this test matters particularly for foreigners who move to Poland during the year, work in Poland, or divide their life between two countries. A conflict of tax residence may arise, but this does not remove Polish reporting duties.
Practical example
Consider the following situation which is very common for expats moving between Germany and Poland.
A German citizen moves to Poland and starts working for a Polish employer. At the same time he still keeps an apartment in Berlin and maintains family and social contacts in Germany.
During the year he spends more than 183 days in Poland and performs his employment duties here. From the perspective of the Polish tax authorities these circumstances are sufficient to treat him as a Polish tax resident for that tax year.
Even if German tax authorities simultaneously treat him as a German tax resident, this does not eliminate the Polish reporting obligation. Such situations are known as conflicts of tax residence and are resolved later under double tax treaty rules.

When do you file and pay tax in Poland
If you had the status of a Polish tax resident in a given tax year, that year is settled in the following calendar year in the Polish annual tax return.
Income earned in 2025 is reported in Poland in 2026 and must be declared by the statutory deadline.
The deadline for filing the Polish annual tax return and paying the tax due is 30 April of the following year.
