PIT-0 under 26, NFZ insurance and the refund students skip

Under Polish law, you're generally treated as a Polish tax resident if you spend more than 183 days in Poland in a tax year, or if your centre of vital interests (personal or economic ties) is in Poland. Most full-time international students who live in Poland through the academic year cross this threshold and become Polish tax residents for that year, meaning Polish tax rules (including PIT-0 if eligible) apply to income earned in Poland. This is a general rule with real exceptions (tax treaties, partial-year arrivals) — if your situation is unusual, a quick consultation with your university's international office or a Polish tax advisor is worth it before your first filing.

In practice, almost every Bangladeshi student working a normal part-time job in Poland only ever deals with their PESEL for tax matters — a NIP becomes relevant only if you start freelancing or registering your own business activity, which is a separate, more advanced step.

If you're under 26, income from an employment contract (umowa o pracę) or a contract of mandate (umowa zlecenie) up to roughly PLN 85,528 per year is exempt from personal income tax (PIT) under the PIT-0 (Ulga dla młodych) relief — this figure is set in law and can be adjusted, so verify the current ceiling before assuming it hasn't changed. Crucially, PIT-0 removes income tax, but it does not automatically remove ZUS social insurance contributions or the NFZ health insurance contribution that apply on certain contract types — those are separate deductions governed by different rules, and what's deducted depends heavily on whether you're on umowa o pracę or umowa zlecenie and whether you're also a full-time student.

This is why umowa zlecenie is often the most financially attractive contract type specifically for full-time students under 26 — it combines the PIT-0 income tax exemption with a ZUS exemption, meaning a larger share of gross pay reaches your bank account than almost any other work arrangement in Poland. Always confirm your specific contract's deductions on your payslip (odcinek wypłaty), since employers sometimes apply relief incorrectly and you can lose out if you don't check.

Employers withhold an advance tax payment (zaliczka na podatek) from each umowa zlecenie or umowa o pracę payment throughout the year based on estimated annual income — this is why your actual annual PIT-37 filing often results in a refund: withholding during the year is frequently higher than your true final liability once annual allowances are applied.

Students who are formally employed in Poland (with contributions paid via their employer) are typically automatically covered under the NFZ (Narodowy Fundusz Zdrowia) public health system. Students without qualifying employment can register for voluntary NFZ coverage through their university, at a contribution of roughly PLN 55–60/month (≈ ৳1,815–1,980), which is usually cheaper than most private international student insurance policies over a full year — but many students still need private insurance for the initial visa application period before NFZ registration is possible, since the embassy requires proof of valid insurance from day one. Compare the total annual cost and coverage scope of voluntary NFZ against a private policy (e.g. Signal Iduna, LUX MED, or your blocked-fund provider's bundled insurance) before deciding which to carry once you're settled.

1. 1

   Collect your PIT-11 from every employer

   Each employer or umowa zlecenie payer is required to issue you a PIT-11 form summarising your annual income and tax withheld, usually by the end of February.

2. 2

   Log in to e-Urząd Skarbowy (podatki.gov.pl)

   The Polish tax authority's online portal often pre-fills a PIT-37 draft using data reported by your employer(s) — review it carefully rather than assuming it's complete.

3. 3

   Apply the PIT-0 relief and any other deductions you're entitled to

   Confirm the pre-filled form correctly applies your under-26 relief if eligible — errors happen, especially with multiple employers in one year.

4. 4

   Submit by 30 April

   This is the standard annual deadline for PIT-37 covering the previous calendar year — confirm the exact date each year on podatki.gov.pl, since it can shift slightly.

5. 5

   Track your refund

   Refunds are typically paid out within about 45 days of e-filing (longer for paper filing) directly to the bank account you list on the form.
