As a general rule a natural person in Poland is taxed based on their tax residency. The criteria for determining tax residence in Poland are set out in Article 3(1a) of the PIT (Personal Income Tax) Act.
Having tax residency in Poland is connected with the obligation to settle income in Poland on the basis of unlimited tax liability referred to in Article 3(1) of the PIT Act.
Natural persons, if they have their place of residence in the territory of Poland, are subject to taxation on their total income (revenues) regardless of the location of the sources of revenue (unlimited tax liability).
On the other hand, lack of tax residency in Poland means being subject to a limited tax obligation referred to in Article 3(2a) of the PIT Act. Natural persons, if they do not have their place of residence in the territory of Poland, are subject to tax liability only on income (revenues) earned in the territory of Poland (limited tax liability)
Having a place of residence in the territory of Poland includes two criteria: staying in the territory of Poland for more than 183 days in a tax year or having a centre of vital interests, understood as a centre of personal interests or a centre of economic interests, in the territory of Poland. The conjunction “or” means that the fulfilment of at least one of these criteria allows a taxpayer to be deemed to be a resident of Poland. At the same time, each of these criteria should be considered independently and independently.
The criterion of the length of stay should be considered to be met after exceeding 183 days of stay on the territory of Poland in a given calendar year (the calendar year is the basic tax period taken into account when making tax settlements of natural persons). Failure to exceed this number of days of residence in the territory of Poland in a given calendar year results in failure to meet this criterion. In such a case, the assessment of the taxpayer’s residence in the territory of Poland is based on the second criterion, related to the location of the centre of vital interests in Poland.
Personal interests centre, or ‘concentration’ of personal interests, is to be understood as the place with which the taxpayer has close personal ties. Personal ties are the presence of family ties, social ties, involvement in social, cultural, sporting, political, etc. activities. In practice, the factor most often taken into account is the presence in Poland of a spouse, partner or minor children.
