Foreign individuals: How to grant an authorisation for tax matters

In Finland, you can take care of your own matters in official e-services or use the services on the behalf of a company or another individual. If you want to act on behalf of someone else, you need Suomi.fi authorisation. There are different authorisations for different situations, and you will have to request them separately.

Foreign individuals cannot use e-services for tax matters yet

At present, foreign individuals cannot use Finnish e-services for their official tax matters or authorise another person or company to use them on their behalf. An individual must have a Finnish personal ID and an electronic means of identification to be able to use the Tax Administration’s e-services.

Authentication methods that would allow foreign individuals to use Tax Administration e-services are currently under development.

Foreign companies can use e-services

A representative of a foreign company can use MyTax and other e-services on the company’s behalf if they have a Finnish personal ID or a foreign individual’s unique identifier (UID) as well as a Suomi.fi authorisation. The representative must request the UID and the Suomi.fi authorisation separately.

You can already make the requests for the UID and Suomi.fi authorisation, but you cannot use them in MyTax or other Tax Administration e-services until the autumn of 2020.

    When you receive a notification that your Finnish Authenticator can now be used for identity authentication, you can request Suomi.fi authorisation.

    Make a request for authorisation

  • See what type of authorisation you need

    There are different types of Suomi.fi authorisations for different situations. The “Managing tax matters” authorisation allows you to take care of all of the company’s tax matters. The “Filing tax returns” authorisation, on the other hand, only allows you to file tax returns on the company’s behalf. Click the link on the header to read more about the authorisation types.
  • Who makes the authorisation request?

    The request for authorisation can be made by a party who has the right to represent the company, for example. The authorisation request must be signed by a party who has the right to sign for the company. The parties with the right to sign for the company are listed in the company’s trade register extract. A certified copy of the extract must be enclosed with the request. The authorisation request can concern either a right to grant authorisations or a representative’s right to grant authorisations.
  • Right to grant authorisations

    A right to grant authorisations must be requested for the matters that the company must take care of using the e-services. The right of authorisation can be registered to one or multiple individuals. Individuals with the right to grant authorisations can log in to the Suomi.fi authorisation service and grant an authorisation either to themselves or to a company employee or an accounting firm. For example, the authorisation can allow the authorised party to use Tax Administration e-services on the company’s behalf.
  • Representative’s right to grant authorisations

    Representative’s right to grant authorisations can be requested for an individual who represents a company or organisation that has been authorised by another individual, company or organisation. When an individual has the representative’s right to grant authorisations, they can grant authorisations to other individuals to act on the behalf of the company or organisation that they represent. These individuals can then act in the name of the company or organisation they represent to take care of matters on the behalf of the party that authorised their company or organisation.
  • Fill in the authorisation request form

    Fill in the authorisation request form on the Suomi.fi e-service and print it out. Send the request by post along with a trade register extract certified by an official authority and legalised with an Apostille certificate as well as other necessary enclosures. Click the link on the header to get more detailed instructions on Suomi.fi.
  • Your request will be processed

    You will be notified by e-mail when the requested right to grant authorisations has been registered.
  • Grant an authorisation to yourself or to a company employee or an accounting firm

    After the right to grant authorisations or representative’s right to grant authorisations has been registered, you can manage the company’s authorisations. Log in to the Suomi.fi authorisation service with your UID. In the e-service, you can grant Suomi.fi authorisations on the behalf of the company you represent. For example, you can grant the authorisation for managing tax matters to yourself or to a company employee or an accounting firm. If you want to authorise an employee to act on the company’s behalf, they must have a Finnish personal ID or a UID.
