First, select a name for your company. To gain an exclusive right to the name, you should report it to the Trade Register maintained by the Finnish Patent and Registration Office (PRH).
Open a bank account for your business. The company will require a bank account to pay share capital, process payment transactions and support accounting.
Establishing and registering a business requires start-up notification forms and establishment documents.
In addition to this, you must register the new company in the Trade Register and various Tax Administration registers. This can be done using a single start-up notification form (Y form).
You can find all the forms and relevant instructions on these pages.
You can also establish a limited liability company online. You can do this through the BIS online service (available in Finnish and Swedish), or you can create a workspace at My Enterprise Finland. Through the My Enterprise Finland service, you also gain access to a wealth of other useful services (requires logging in with online banking credentials).
