Poland PIT employer annual information returns

Poland: annual PIT-11, PIT-4R and PIT-8AR employer information returns due 31 January (to the tax office)

Gemini candidate audit (2026-09-08), confidence: likely. The 31 January electronic-filing deadline to the tax office is well-established, stable PIT law (in force since the 2019 e-filing reform); not independently re-confirmed against a live official page this session beyond the general podatki.gov.pl płatnik guidance already cited elsewhere in the dataset.

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

Every Poland-registered employer that withheld PIT advances on employee salaries, board-member remuneration, or other PIT-withholdable payments during the year.
