Poland environmental-use fee (opłata za korzystanie ze środowiska)

Poland: annual environmental-use fee (opłata za korzystanie ze środowiska) due by 31 March

Re-verified 2026-09-09 on biznes.gov.pl/pl/portal/ou133 ("Opłaty środowiskowe"): "Wykaz za dany rok kalendarzowy złóż do dnia 31 marca następnego roku", confirming the 31 March deadline. The page also gives exact de-minimis thresholds: no filing required if the calculated annual fee for a given category is at or below PLN 100, and no payment required (but filing still required) at or below PLN 800, under the Prawo ochrony środowiska (2001).

Next: 31 March 2027then 31 March 2028, 31 March 2029

Businesses operating vehicles or other emission/water-use sources in Poland above the de-minimis threshold - like the KOBiZE report, this reaches beyond heavy industry to ordinary companies with a company vehicle fleet.
