Note sur la date : Re-checked 2026-09-09: podatki.gov.pl/pit/twoj-e-pit is reachable but is a collapsed navigation page with no extractable deadline text this session. 30 April remains the stable, long-standing statutory deadline under PIT Act Art. 45(1); not independently re-confirmed against live page text.
Chaque année en avril, avant le 30. · Covers the prior calendar year. Applies to self-employed individuals taxed on the general scale or the 19% flat rate; those on a lump-sum (ryczałt) or tax-card scheme file a different annual return (PIT-28) with a different deadline, not covered by this entry.
Ce qui change

This is the single most important annual deadline for a self-employed taxpayer and was entirely absent from the existing Poland dataset entries.
