Corporations are due to file their tax returns soon

News, 4/19/2022

Corporate taxpayers whose accounting period ended in December 2021 are due to file their tax returns by Monday 2 May 2022. Corporations include limited liability companies, housing or real estate companies, associations, foundations, municipalities, and foreign corporations.

Submit the tax return and the necessary attachments in MyTax. Alternatively, you can send them as a file in the Ilmoitin.fi service or through a software interface.

Request extended time, if needed

If necessary, you can request an extension of time for filing the tax return, but only if you have a valid reason, such as an illness. Send your application to the Tax Administration before the tax return’s filing deadline. You can request an extension of time in MyTax or on paper (Form 3105).
