Non-Finnish users – How to use the Katso ID (individuals authorised to sign for their company)
When your Katso ID is active, you can sign in to the participating e-services for your company or authorise someone in your company to act on its behalf. In that case your employee will need a Katso ID.
For guidance on how to authorise someone, go to page Katso - Detailed instructions, section Authorisations.
If your company does not use e-services by itself, you can authorise an agent: Katso instructions for authorizing another party (usually an accounting firm).
If your company acts as an agent, your client must authorise you to act on their behalf: Katso instructions for agents.
