PIT-37 Tax Declaration Calculation
What is it?
📌 PIT-11 is an official document that you receive from your employer at the beginning of each year (usually by the end of February). It contains all the information about your income, paid taxes, and social security contributions (ZUS) for the previous year.
🔹 What does PIT-11 include?
✔ The total amount of your earnings (gross)
✔ Deducted taxes (advance payments on income tax)
✔ Contributions to social (ZUS) and health insurance
✔ Other additional payments or deductions
This document serves as the basis for filling out your annual tax return (PIT-37).
📌 PIT-37 is a tax declaration that you must submit to the tax office (Urząd Skarbowy) for the previous year.
🔹 Who must file PIT-37?
✅ All employees working under an employment contract (umowa o pracę) or a civil law contract (umowa zlecenie, umowa o dzieło)
✅ Individuals who received income exclusively from Polish employers
✅ Workers whose taxes were automatically deducted by their employer
💡 Why is it important to file PIT-37?
It's mandatory! Everyone who has worked in Poland must settle their taxes. Even if you earned a small amount or worked for just a few months, you are required to file the declaration.
You may receive a tax refund! In most cases, people pay more taxes than required, so the government returns the overpaid amount.
📌 How much money can you get back?
💰 Refund amounts can be significant!
Depending on your income, taxes paid, and available tax reliefs, the refund can range from a few hundred to several thousand zlotys.
🔹 Factors influencing the refund amount:
Official marriage – the ability to file jointly with your spouse (reducing taxable income).
Children – if you have minor children, you will receive additional tax benefits.
Internet expenses – can be partially deducted from taxes.
Charitable donations – can also reduce your tax amount.
📅 When is the PIT-37 deadline?
The declaration must be submitted by April 30 each year.
