Polish taxpayers working abroad must understand how to correctly declare foreign income and utilize double taxation avoidance mechanisms when filing their 2026 PIT returns.
When to Declare Foreign Income in Poland?
The obligation to declare foreign income depends primarily on tax residency. A person is considered a tax resident if they have their place of residence in Poland.
How to Avoid Double Taxation?
Poland has concluded double taxation avoidance agreements with many countries. These agreements determine where and how income is taxed.
Two main methods are typically applied:
1. Exemption with Progression
This method is used, for example, for work in countries like Germany, the United Kingdom, or France.
2. Proportional Credit Method
This method is less favorable and often requires a tax top-up in Poland.
How to File PIT with Foreign Income?
Depending on the situation, the taxpayer should choose the appropriate method and complete the necessary forms. In some cases, it is also possible to use the abolishment relief.
Abolishment Relief – When Can It Be Used?
Abolishment relief mainly applies to the proportional credit method. It limits the difference between the tax paid abroad and the Polish tax liability.
Currently, the relief is limited to a cap (up to 1,360 PLN), meaning it doesn’t always eliminate the tax top-up.
Common Taxpayer Errors
Taxpayers working abroad often make mistakes when filing their PIT returns. Common errors include incorrect declaration of income, improper application of tax treaties, and failure to convert income to PLN.
Such errors can result in the need to file a correction and pay outstanding tax.
Example Calculation
A taxpayer worked in Germany and earned 50,000 PLN (after conversion). This may result in a higher tax rate for domestic income.
The application of the tax method depends on the specific international agreement and the type of income.
Summary
Filing PIT with foreign income requires determining tax residency and applying the appropriate double taxation avoidance method. International agreements and accurate form completion are crucial.
Carefully analyze your situation – incorrect filing can result in overpayment or tax arrears.
