Authorised Intermediary: How to get access to Finnish Tax Administration’s e-service MyTax
As an Authorised Intermediary you can read the information requests related to TRACE returns in MyTax in addition to regular mail. You can also view your annual returns or see how much dividend has been forwarded to you on e-service.
In order to get an access to MyTax a foreign authorised intermediary needs to make an application to register an electronic power of attorney in Suomi.fi e-authorization register.
Before making an application find out who (one or several persons) will be authorized to independently manage mandates in Suomi.fi e-Authorizations. Usually it is the person who has signatory rights of the company entered into the Trade register. The person with signatory rights usually also signs the application.
In order to ease the administrative burden for signatories, it is possible to authorize another person (for example a person who manages the company's mandates) to make the application and sign it. The following instructions applies to such procedure.
Instructions
Authorize a person to sign the application to register an electronic power of attorney
The signatory of the company (entered into the Trade register) authorizes a person who will sign the application to register an electronic power of attorney in Suomi.fi e-authorization register. Note that authorization needs to be made as a written power of attorney and the power of attorney must be certified. Read more about notorisation of foreign documents (suomi.fi).

Select Grant a mandate to a person.
If the person does not have a Finnish personal identity code, you will need their foreigner’s user identifier (UID).
Step 3: Selecting mandate themes
Select Managing of tax affairs as mandate theme.
Step 4: Specifying the period of validity
A mandate must always have a start and end date. The mandate may be valid for a maximum of 25 years from the day on which it was granted. Note that if the assignee’s identifier is the foreigner’s user identifier (UID), the mandate will be valid for no more than 3 years.
Step 5: Mandate validation
Check mandate details:
- The assignor is a company (authorised intermediary´s business ID)
- The assignee is a person that can act on behalf of the authorised intermediary
- The mandate type is Mandate for transactions
- The mandate theme is Managing of tax affairs
- The selected period of validity of the mandate is correct
If you wish to change the details before the mandate is validated, you can go back over these steps.
The mandate you have granted becomes valid from its start date once you have validated it.
