Logging in to MyTax via Suomi.fi in November

Tax Administration Bulletin, 9/11/2018

In November 2018, the Finnish Tax Administration will introduce Suomi.fi authorisations for managing tax matters. Only one authorisation will be in use in MyTax: Managing tax matters.

Both individual and corporate taxpayers can use the Managing tax matters authorisation for authorising another individual or company to take care of their taxes.

You can grant authorisations to others in Suomi.fi e-Authorisations already today, but the new authorisations will not work in MyTax before November.

After an agent has been granted a Suomi.fi authorisation for managing tax matters, they can log in to MyTax with their online banking codes, mobile certificate or certificate card. Authorisations come into effect as soon as both parties have accepted them. After that, the authorised agent has access through MyTax to all tax matters of the authorising party, both business-related and private.

All tax information about the authorising party is available to the agent. The agent can view, correct and submit both the company’s tax information and the authorising party’s personal tax information.

New Katso authorisation for self-employed individuals and operators of agriculture or forestry

If an agent acting for self-employed individuals or operators of agriculture or forestry does not activate a Managing tax matters authorisation in Suomi.fi, they must apply for a new Katso role for managing matters in MyTax.

The new Katso role, MyTax for individuals and entrepreneurs, is valid only in MyTax as from November 2018.

The MyTax for individuals and entrepreneurs role must be activated if, for instance:

  • the company form of the agent is other than limited liability company, limited partnership, general partnership or self-employed (for instance association or business partnership);
  • the authorising party is not using an electronic identifier (personal banking codes, eID card or mobile certificate).

Katso and Suomi.fi authorisations can be used in parallel, which means that the agent has both the Managing tax matters authorisation and the MyTax for individuals and entrepreneurs role.

If a self-employed individual or an operator of agriculture or forestry manages their taxes in MyTax themselves, they need not apply for a Suomi.fi authorisation. Instead, they can log in to MyTax with their individual online banking codes or mobile certificate, as before.

Companies can also switch to Suomi.fi eAuthorisations

For agents of limited-liability companies, housing companies, limited partnerships and general partnerships, login to MyTax will work as before with the Katso identifier. However, we recommend that all users switch to Suomi.fi authorisations soon, as Katso authorisation will no longer be in use after 2019.

Some Katso roles will also be discontinued. As from November, My Tax can no longer be accessed with the Company's income tax returns and Filer of self-assessed taxes roles. At present, these roles are used by only approximately one percent of all users.

Only the following Katso roles function in MyTax:

  • Company’s Master User
  • Company’s Parallel Master User
  • Company MyTax
  • MyTax for individuals and entrepreneurs (only available to those who manage tax matters on behalf of self-employed individuals)

Note: For the time being, Suomi.fi authorisations are not available to the following legal entity forms or their agents: consortium, estate of a deceased person, joint benefit administration, foundation, association, foreign entity, and public body. These legal entities and their agents must log in to MyTax with a Katso identifier.

Official roles listed in the Trade Register can access MyTax without authorisation

You will be able to manage the taxes of the company you represent and access its MyTax automatically if you have one of the following official roles in the Trade Register or the Business Information System:

  • Managing Director
  • Chairman of the Board
  • individual authorised to sign for the company
  • authorised signatory
  • Building  Manager
  • partner
  • liquidator

The people whose role is one of the above also have the authority to have the company’s bank account number saved in MyTax, and to change the account number entry in MyTax.

If you have one of the following official roles, you can grant authorisations on behalf of the company:

  • Managing Director
  • individual authorised to sign for the organisation
  • individual who has been granted the right to do so by the Managing Director or by an individual authorised to sign for the organisation

Private individuals granting authorisations to another person or to a company

As a private individual, you can grant a company or another individual a Suomi.fi authorisation for managing tax matters on your behalf. When you have granted the Managing tax matters authorisation to the authorised party, they can use MyTax to make corrections and additions to your personal tax return, etc.

In other words, after the authorisation is granted, the party authorised as your agent can access all your tax facts and information. The agent can view, correct and submit the authorising party’s information, and receive, for instance, tax correspondence and decisions concerning the authorising party, as well as change the bank account number.

Managing the taxes of an underage child

If you have an underage child, you can take care of their taxes in MyTax as of November 2018. The e-Authorisation service automatically checks with the Population Information System to see if you have a guardian’s right to manage the tax matters of your underage child.
