The Business Information System (BIS) is a joint service for businesses and organisations that are clients of the Finnish Tax Administration, Trade Register or Register of Foundations.
>> Business Information System
BIS enables businesses to report their company information to both authorities in one single notice. Businesses and corporations no longer need to report the same information on separate forms to both the Trade Register and the registers kept by the tax administration.
The Business Information System includes businesses and corporations entered into the
- Trade Register
- Foundations Register
- VAT register
- Withholding Tax Register &/or
- Employer Register
All businesses and corporations to be entered into the Business Information System are given a Business Identity Code (Business ID).
