Notification of changes - co-operatives

If changes occur within your co-operative, you must immediately file a notification of changes with us to keep your records up to date at the PRH Trade Register, and in the VAT Register, Prepayment Register and Employer Register at the Finnish Tax Administration.

Notification of beneficial owners

All co-operatives must file a notification of their actual beneficial owners with the Finnish Trade Register and thereafter keep the details in the Trade Register up to date.

Filing the details of beneficial owners is free of charge.

The co-operative must file a notification even if the co-operative has no beneficial owners or the co-operative does not know them. Read more about filing details of beneficial owners.
