e-Filing Income tax returns – corporate taxpayers

From 1 November.2017, corporate entities must file their income tax return electronically. You can file on paper only if there is a special reason (for example, if electronic filing is impossible due to technical difficulties).

If you are authorised to represent a limited liability company, a cooperative society or a non-mutual real estate company, log in to MyTax to file its tax return (which you would otherwise do by submitting Form 6B on paper) including its enclosures.

If your company accounting software creates a computer file serving as an electronic version of the income tax return, log in to Ilmoitin.fi to send it to us.

Another way to e-file an income tax return is via Tyvi service providers:
