When does a UAB file its corporate income tax return?
Last updated: Oct 21, 2026, 17:46 (UTC+08:00)
A UAB files form PLN204 and pays the tax by the 15th day of the sixth month after the tax year, which is 15 June for a calendar year. If taxable income in the previous period exceeded €300,000, the company also pays advance corporate income tax during the year.
