The online authorisation mandate

You can use the feature called “Suomi.fi Authorization” to enable you to deal with another person’s taxes through e-services, over the telephone, or by visiting a service point on their behalf.

Letters of authorisation on paper

You can receive a letter of authorisation from the other person. It will enable you to deal with that person’s taxes on the telephone, by visiting a service point on their behalf, or by submitting information on paper tax forms. To have a letter of authorisation (often called a ‘power of attorney’) does not provide access to MyTax.

When is there no need for an authorisation mandate?

The following circumstances are examples of when you can deal with someone else’s taxes with no authorisation.

You have child younger than 18 and you handle the child’s taxes

You are automatically authorised to access MyTax for the child, without an authorisation. Log in to MyTax and select “Act on behalf of someone else”.

You are a guardian

You do not need a Suomi.fi authorisation when your continuing power of attorney for being a guardian is officially confirmed, or when you are registered as a private guardian. Log in to MyTax and select “Act on behalf of someone else”.

Read more: “You are a private guardian or have a continuing power of attorney to act as guardian” on the Authorisations page.

Note: If you are a public guardian, in other words, a public official employed by a public guardianship office, you can only use paper forms.
