Complete Guide To Completing Pit-37 And Pit-11 In Poland 2024
PIT-37 is a tax return required to be filed by every taxpayer in Poland, the purpose of which is to determine the amount of personal income tax (PIT).
Form PIT-11, in turn, is a document that is issued to employees by their employers and contains data on income earned over the past year. This information is necessary to correctly fill out the PIT-37 declaration.
When Should I Fill Out Pit-37?
To complete the PIT-37 tax return for the year 2023, you must do so by May 2, 2024. This is the last day you can submit documents to the IRS to avoid penalties. Those who fail to submit a declaration on time may face financial penalties ranging from 100 to 1200 zlotys.

The obligation to fill out PIT-37 falls on everyone who has permanent residence in Poland or receives income in the country. The list of such income includes:
- Salary from work;
- Profit from business activity;
- Income from rental property;
- Interest;
- Income from transactions with securities;
- Other sources of income.
Poland uses a progressive tax scale, according to which the tax amount increases depending on the amount of income.
Tax rates in 2023 are set as follows:
- Up to PLN 85,528 – 17%;
- From PLN 85,528 to PLN 146,832 – 22%;

What Are Pit-11 And Pit-37?
PIT-11 and PIT-37 are tax forms that reflect an employee's annual income, but serve different purposes.
Form PIT-11 is provided to the Internal Revenue Service by the employer for each employee and may include information about advance tax paid, but may not reflect the exact amount of income earned. The document must be submitted before the beginning of March of the following year, and if the employee worked for several employers, each of them is required to submit PIT-11 for him.
Unlike PIT-11, Form PIT-37 is submitted by the employees themselves and contains information about income earned and taxes paid for the year. This declaration serves as the basis for the government to refund part of the taxes if the employee is entitled to tax deductions.
Amount Of Tax Paid On Salary
Poland has a system of tax thresholds that determines the amount of tax depending on annual income:
For incomes up to PLN 85,528, a tax of 18% is applied, from which PLN 556 is deducted.
For income above this amount, a flat fee of PLN 14,839 is levied, plus 32% tax on amounts exceeding PLN 85,528.
The specified income limit of PLN 85,528 may be adjusted in the next tax year, increasing or decreasing depending on changes in legislation.
