Do I need my own Y-tunnus (Business ID)?

Operating as a sole trader (toiminimi) requires your own Y-tunnus (Business ID). With Truster's sole trader service, you can easily get both a toiminimi and a Y-tunnus – we help you with both setting it up and getting started. If you already have a Y-tunnus, you can still start using the service and smoothly transfer your business to Truster.
