Poland: annual environmental-use fee (opłata za korzystanie ze środowiska) due by 31 March
Gemini candidate audit (2026-09-08), confidence: uncertain. The 31 March deadline and Prawo ochrony środowiska legal basis are well documented in Polish environmental-compliance practice, but this could not be independently re-confirmed against a live official page this session, and there is a known de-minimis exemption (fee below a small annual threshold) whose current PLN value was not verified.
Nästa: 31 mars 2027sedan 31 mars 2028, 31 mars 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.
