Tax residence determines which income you pay tax on in Poland. We explain when a foreigner becomes a Polish resident, how unlimited and limited tax liability differ and what this means for the HR department.
1. When you are a Polish tax resident
Under Article 3(1a) of the Personal Income Tax Act (the PIT Act), a person is deemed to have their place of residence in Poland if they meet at least one of the conditions: they have their centre of personal or economic interests (centre of vital interests) in Poland, or they stay in Poland for more than 183 days in the tax year. The conditions are joined by "or" — one is enough.
2. The 183-day rule and the centre of vital interests
The 183-day limit counts every day of physical presence in Poland in the calendar year — including the day of arrival and departure as well as weekends and holidays. In practice, however, the centre of vital interests is often more important than the number of days: if your centre of personal (family) and economic (work, assets, income) affairs is in Poland, you may be a resident even with a shorter stay.
3. Unlimited vs. limited tax liability
| Status | What is taxed in Poland | Basis |
|---|---|---|
| Unlimited (resident) | On all income — Polish and foreign | Article 3(1) of the PIT Act |
| Limited (non-resident) | Only on income earned in Poland | Article 3(2a) of the PIT Act |
4. Dual residence and what it means for HR
When two countries consider you a resident, the conflict is resolved by the double taxation treaty (DTT) and its tie-breaker rules. Applying a DTT usually requires a certificate of residence. For the HR department, residence status affects the withholding of PIT advances — establish it with the employee in writing at the start of employment.

Scenarios and risk assessment
Stay < 183 days, family abroad: usually a non-resident (low risk). Stay > 183 days, family abroad: dual residence possible — resolved by the DTT (medium risk; a certificate of residence is advisable). Moving with the family: usually a resident from the moment the centre of life is transferred, with possible "split-year residence" (risk of misreporting foreign income).
How to document the centre of interests
It is worth gathering evidence: the employment contract and place of work, a lease agreement or title deed, bills, proof of the family's stay, insurance. In a dispute with the authority, these are the first circumstances you will rely on.
