Polish taxpayers must submit their annual PIT tax returns between February 15 and April 30, 2026, for the 2025 tax year.
Filing Period for PIT 2025
The annual tax return, known as PIT, is submitted from February 15 to April 30 of the year following the tax year. For PIT 2025, taxpayers should file between February 15 and April 30, 2026.
Early Submission Rules
If submitted before the opening date, the tax office will not process the document immediately. It will be treated as if it arrived on February 15.
Methods for Submitting Tax Returns
A tax return can be submitted electronically via services like Twój e-PIT on the e-Urząd Skarbowy platform or through e-Deklaracje. Alternatives include mailing via Poczta Polska only or filing in person at a tax office.
Critical Deadline for Mail Filers
The envelope must be sent to the tax office before the deadline. The final date is April 30, 2026; the postal stamp date is decisive.
Penalties for Late PIT Submission
Filing on time avoids criminal tax liability and prevents the accrual of late payment interest. Timely compliance with tax obligations is essential.
