How can I manage the taxes of my underage child in MyTax?

To take care of the tax matters of your underage child, log in to MyTax and select “Act on behalf of someone else”.  

Exceptions:  

• If a child has a non-disclosure order for personal safety reasons, their guardians cannot act on their behalf. 
• If all the guardians of a child have a non-disclosure order for personal safety reasons, none of them can act on behalf of the child. 
• If only one of the guardians has a non-disclosure order for personal safety reasons, only the guardian with the non-disclosure order can act on behalf of the child.

These terms are in place to protect information covered by non-disclosure.  

If none of the guardians can act on behalf of the child, a separate Suomi.fi authorisation is needed, and each guardian must accept the authorisation. The person with the Suomi.fi authorisation can then act on behalf of the child. To grant and accept an authorisation to manage tax matters, you need to go to the Suomi.fi e-authorisation service.

If the child has personal online banking codes, they can use MyTax themselves.
