Missing the 30 April Polish tax deadline does not mean the situation is unresolvable. The Polish fiscal system has a formal voluntary correction mechanism — czynny żal — that allows you to file a late or corrected return before the tax authority identifies the issue and initiate proceedings. Used correctly, it significantly reduces penalties and in some cases eliminates them entirely. Used too late, it is unavailable.
The distinction is simple: you acting first versus them acting first. Everything that follows depends on which happens first.
What Czynny Żal Actually Does
| Your Situation | Penalty Position Without Korekta | Penalty Position With Czynny Żal |
|---|---|---|
| Late filing — return not submitted by 30 April | Interest at 14.5% per annum from 30 April plus late filing penalty | Interest still applies from 30 April — but penalty significantly reduced or eliminated if voluntary |
| Incorrect return — income understated | 30% penalty on understated tax in standard cases — 75% where evasion established | Penalty eliminated if voluntary correction submitted before authority identifies the error |
| Wrong form filed — PIT-37 instead of PIT-36 | Treated as incorrect return — interest from original deadline | File correct form with czynny żal — interest applies, penalty reduced |
| PIT-39 not filed — property sale within 5 years | Full 19% liability plus interest from 30 April plus non-filing penalty | File PIT-39 now with czynny żal — interest applies from 30 April, penalty position significantly better |
How to Submit Czynny Żal
Czynny żal is a written notification submitted to your local Urząd Skarbowy — the tax office corresponding to your registered address in Kraków. It must accompany or immediately precede the late or corrected return. It is not a form — it is a letter that acknowledges the error, identifies the tax year and return type affected, confirms you are filing voluntarily, and states that you are not aware of any proceedings already initiated by the authority.
The notification can be submitted: in person at your Urząd Skarbowy, electronically through the e-Urząd Skarbowy portal at podatki.gov.pl using your Profil Zaufany, or by registered post. Electronic submission creates a timestamped record — the most important protection if the authority subsequently claims they had already initiated proceedings before your submission arrived.
Czynny żal is not available if the Urząd Skarbowy has already initiated formal proceedings for the relevant tax year and return type. The critical check before submitting: have you received any correspondence from the Urząd Skarbowy about your 2025 tax return? A letter, an email notification through e-Urząd Skarbowy, or a phone call from the authority counts as initiated proceedings. If yes — czynny żal is unavailable and you need a Polish tax adviser or lawyer immediately.
If no correspondence has been received, submit czynny żal immediately. Do not wait to confirm whether they have noticed. The protection exists only while they haven't acted.
Filed an incorrect return and not sure whether czynny żal still applies?
Chapter 10 of the Personal Taxes and Legal Requirements Guide covers the czynny żal submission process, the exact situations where it protects you, and what to do if you have already received correspondence from the Urząd Skarbowy.

Did not file at all — Twój e-PIT auto-accepted an incomplete return
If you did not log in and the portal auto-accepted a pre-populated return that was incomplete — for example, missing foreign income or a PIT-39 obligation — you have filed an incorrect return, not a missing return. The correction process is a korekta (amended return) rather than a late filing. File the corrected return with a czynny żal notification as soon as possible.
Filed PIT-37 but should have filed PIT-36
If you had foreign income, freelance earnings, or rental income and filed PIT-37, you filed the wrong form. Submit a PIT-36 as a korekta covering the complete income picture. Include czynny żal. The original PIT-37 is superseded by the corrected filing.
Did not file PIT-39 for a 2025 property sale
If you sold property in Poland in 2025 within the 5-year window and did not file PIT-39 by 30 April, file PIT-39 now with a czynny żal notification. The 19% Belki tax on your net gain is due immediately with interest from 30 April. The voluntary correction eliminates or reduces the non-filing penalty — but the tax and interest are payable regardless.
What You Need to File Now
| Your Situation | Action Required | Where to File |
|---|---|---|
| No return filed — straightforward employment, no other income | File PIT-37 immediately with czynny żal notification | podatki.gov.pl — Twój e-PIT still accessible after 30 April for late filing |
| Auto-accepted incomplete return — foreign income missing | File PIT-36 korekta with czynny żal | podatki.gov.pl — select korekta option on the relevant return |
| PIT-39 not filed — property sale in 2025 | File PIT-39 with czynny żal — pay tax and interest immediately | podatki.gov.pl — PIT-39 form for 2025 tax year |
| Received correspondence from Urząd Skarbowy about 2025 return | Do not file without legal advice — czynny żal may be unavailable | Polish tax adviser (doradca podatkowy) immediately |
