Self-employed individuals: how to authorise someone else to take care of your tax matters

If you act as a representative for another party in their tax matters, you can request authorisations in the Suomi.fi e-authorisation service. Instructions on Suomi.fi: Request a mandate as a company or an organisation

Restrict what information your agent can see

If you grant your agent a Suomi.fi authorisation for tax matters, the agent can see, edit and file tax details related to your business activities and personal tax matters.

If you do not want your accountant or agent to see your personal tax data, do this:

  • Go to Suomi.fi and grant your accountant an authorisation for specific tax matters. For example, the “Filing of tax returns and other reports” authorisation allows your accountant to file all necessary tax returns on your behalf.
  • Log in to MyTax with your personal e-bank codes, copy all the necessary details, and send them to your accountant.
