Finnish Business Information System (BIS at ytj.fi) and Business ID
The Business Information System (BIS) is jointly maintained by the Finnish Patent and Registration Office (PRH) and the Finnish Tax Administration. Joint notifications of the PRH and the Tax Administration are entered in the Business Information System at ytj.fi.
You can use the system to find the companies and entities that
- are entered in the PRH Trade Register or Register of Foundations
- are entered in the Finnish Tax Administration’s Prepayment Register, Employer Register, or VAT Register
- have filed a start-up notification but are not yet entered in any of the registers above.
The PRH or the Tax Administration gives the company a Business ID once the notification is entered in the system at ytj.fi.
