When Do You Become a Polish Tax Resident?
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.
What the 183 day rule means in practice
- 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. This applies equally to people working remotely from Poland for a foreign employer.
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. If you also have foreign income to declare, both tests need to be assessed carefully.
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 under double tax treaty rules.

Double tax treaties and residency conflicts
It is possible for two countries to treat you as a tax resident at the same time. This happens frequently for people who move to Poland mid-year or who maintain strong ties in their home country. The situation is known as a conflict of tax residency.
Poland has concluded double tax treaties with most countries. These treaties contain tie-breaker rules that determine which country has the primary right to tax your worldwide income. The tie-breaker analysis typically follows this order:
Treaty tie-breaker sequence
- permanent home available to you
- centre of vital interests (closer personal and economic relations)
- habitual abode (where you spend more time)
- nationality
- mutual agreement between tax authorities
An important point: the existence of a double tax treaty does not automatically remove your obligation to file a tax return in Poland. Even if the treaty assigns primary residence to another country, Polish tax authorities may still require a return to confirm the treaty position and report income correctly.
The treaty analysis must be done separately for each tax year and each income source. For example, employment income, capital gains and dividends are often treated under different articles of the same treaty.
Did you just become a Polish tax resident?
You may qualify for Settlement Relief
If you recently moved to Poland and became a Polish tax resident, you may be entitled to a significant income tax exemption under the Settlement Relief programme. This relief is designed for people who transfer their tax residency to Poland and meet specific conditions.

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. This applies to all sources of income including foreign income, rental income, and capital gains from investments. Depending on your income sources, the filing may involve a general income return (PIT-36) or a combination of PIT-36 and PIT-38. You can find a full overview of what this involves on our Polish tax return service page for expats.
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.
What happens if you do not file a Polish tax return
Failing to file a Polish tax return when you were a Polish tax resident is not a minor administrative issue. Polish tax authorities actively enforce filing obligations and have access to foreign income data through international exchange of information agreements, including the Common Reporting Standard (CRS) and EU DAC framework.
Practical consequences of not filing
- late filing penalties under the Polish Fiscal Penal Code
- interest on unpaid tax calculated from the original deadline
- risk of a tax audit covering multiple prior years
- potential liability for undeclared foreign income discovered through CRS data
The longer the delay, the more complex the situation becomes. If you are unsure whether you had Polish tax residency in a given year, it is significantly better to assess the situation and file voluntarily than to wait for the authorities to act. Our team handles both current-year filings and past-year compliance for expats in exactly these situations.

Frequently asked questions about Polish tax residency
When do you become a tax resident in Poland?
You become a Polish tax resident if you spend more than 183 days in Poland in a calendar year or if your centre of personal or economic interests is located in Poland.
What is the 183 day rule in Poland?
If you stay in Poland for more than 183 days in a calendar year, you are treated as a Polish tax resident for that tax year. The counting is based on the calendar year, not a rolling twelve month period.
Do expats have to declare foreign income in Poland?
If you are a Polish tax resident, you must declare your worldwide income in Poland, including foreign salary, dividends, capital gains and other income. Double tax treaties may reduce or eliminate the actual tax payable, but the reporting obligation remains.
What is the centre of vital interests test?
Polish tax authorities analyse where your family lives, where you work, where your main assets are located and where your personal and economic life is centred. This test can create Polish tax residency independently of the 183 day rule.
When must you file a Polish tax return?
The deadline for filing the Polish annual tax return and paying the tax due is 30 April of the following year. Income earned in 2025 must be declared by 30 April 2026.
Does registering my address in Poland make me a tax resident?
No. Address registration alone does not determine Polish tax residency. What matters is whether you meet the 183 day test or whether your centre of personal or economic interests is in Poland. Many people are registered without being tax residents and vice versa.
Can I have dual tax residency in Poland and another country?
Yes. Two countries can simultaneously treat you as a tax resident. This is resolved by applying the tie-breaker rules in the applicable double tax treaty. The conflict does not automatically remove the obligation to file a tax return in Poland.
What if I work remotely from Poland for a foreign employer?
If you work remotely from Poland and spend more than 183 days here, or if your personal life is centred in Poland, you may be treated as a Polish tax resident. Your worldwide income including the foreign salary would then be subject to declaration in Poland. The applicable double tax treaty determines where the actual tax is paid.
What are the consequences of not filing a Polish tax return?
Failure to file can result in late filing penalties, interest on unpaid tax, and risk of a tax audit. Polish tax authorities receive foreign income data from over 100 countries through the Common Reporting Standard. Voluntary compliance is always the better option.
