Double Taxation – Where Does It Come From?

Double taxation affects Polish taxpayers who earn money both in Poland and abroad. They must pay tax on income according to the unlimited tax liability. As taxpayers are bound by the principle of source taxation, they must also pay income tax abroad. Such a phenomenon leads to double taxation.

Who is a Polish Tax Resident?

This term refers to taxpayers who meet at least one of the following criteria:

  • Having the centre of vital interests in Poland despite working abroad on a daily basis. This means residing in the country of the closest family, including spouses and children. Other factors include for example owning real estate and investments. Engaging in political, social, or cultural activities also qualifies.
  • Residing in Poland for more than 183 days in the tax year.

In some cases, countries with a double taxation treaty may both recognise the taxpayer as a tax resident. In such cases, the rules of conflict of laws apply. These are provisions in the treaty that help to resolve which country’s tax resident a person is. In most cases, the centre of vital interests is considered more significant.

Poland is a party to many international treaties that guarantee taxpayers the limitation of the negative effects of double taxation. As a result, doing business in Poland does not result in double taxation.

Methods of Avoiding Double Taxation
Exemption with Progression MethodProportional Deduction Method
– Involves taxation only of the income earned in the country of tax residence. The amount of income earned abroad is used to determine the income tax rate that the taxpayer must pay.     – The process proceeds as follows:
1. Calculation of the sum of incomes earned in Poland and abroad converted into the currency of the country of tax residence.
2. Calculation of income tax according to the general rules (tax scale).
3. Determination of the tax rate in Poland. For this purpose, the amount obtained in the second step is divided by the sum of incomes (1) and then multiplied by 100%. The result gives the tax rate.
4. Calculation of the tax due.
– Applies in situations where the taxpayer earns income abroad, but the agreement between Poland and the country where he earns income does not include a provision on the exemption with the progression method. Applies also when no agreement on the avoidance of double taxation has been concluded between the countries

– Provisions regulating this issue can be found in the Personal Income Tax Act.

– When calculating the tax amount due in this variant, it is necessary to sum up the incomes earned in Poland and abroad. Then you should deduct from it the amount of income tax that the taxpayer paid abroad. the resulting amount cannot exceed the portion of income that was taxed abroad.
