Welcome to Finnish Business Information System

The Business Information System (BIS) is a service jointly maintained by the Finnish Patent and Registration Office (PRH) and the Finnish Tax Administration.

Submit information using forms

Businesses, organisations and foundations can submit information to both the PRH and the Tax Administration by using one single notification form. You submit information by filling in a notification form and by sending it to the address given on the form.

  • Download form templates, in Finnish and in English, to register a new business, organisation or foundation (‘Start-up Notification’), or to submit changes or close down business (‘Notification on Amendments or Termination of Business’). Please note that you can use the bilingual forms in Finnish and in English but that you have to fill in them in Finnish or in Swedish. 

Business IDs and company search

All businesses, organisations and foundations recorded in the Business Information System obtain a Business Identity Code (Business ID). BIS Search provides basic details of Finnish businesses, organisations and foundations free of charge.

LEI codes

The Business Information System also provides details about international Legal Entity Identifiers (LEI codes) of companies and organisations that use derivative contracts in financial markets. Download LEI files.

Local register offices and ELY centres will no longer be local authorities in matters relating to the Trade Register and Register of Associations – PRH takes over housing company tasks from local register offices in September a navigation icon

Our online services are becoming more and more popular for submitting information to the Trade Register and the Register of Associations at the PRH. As online services reduce the need for staff processing notifications, all notifications submitted to those registers will be processed at the PRH from 1 September 2015 to provide a competent processing and advisory service. We will also take over the processing of housing company notifications from local register offices.
