• File financial statements with the Finnish Trade Register
• Submit the most common company changes to the Finnish Trade Register and the registers of the Finnish Tax Administration

If you cannot submit your notification or application using the online filing service at ytj.fi, use our online form to send form Y or the application with attachments to the PRH. You will find links to the online forms at prh.fi. 

We will publish updated filing instructions at prh.fi and ytj.fi on 1 January 2026.

The change is based on the new Finnish Trade Register Act

Mandatory online filing is based on the Finnish Trade Register Act and on an amendment to the Finnish Business Information Act. 

We process and register information filed online faster, which also gives everyone quicker access to Trade Register information.
