Notification of changes - associations

If your association has a Business ID, meaning that it has registered with the Finnish Tax Administration or the PRH Trade Register, you must file changes with the Finnish Business Information System (BIS) using paper form Y4. Please note that the PRH Register of Associations is not included in the BIS and that the changes you have reported to the BIS using form Y4 are not automatically forwarded to the Register of Associations. You must also file a separate notification of changes with the Register of Associations.

Change address or contact details

If your association has a Business ID, you must report your postal address or street address to the registers you have registered with.

You may also submit other contact details to us, such as your telephone number, email address or website address.

Use paper form Y4 to report changes to your address or contact details. Please note that online filing is not possible.

Your association address and contact details are public details and available for free to anyone who uses the BIS company search on this website. You will not receive a specific register extract of the changes - use the BIS company search to check them. Go to the search.

Your address and contact details are also available for free from the PRH Virre Information Service.
