How to grant an authorisation for tax matters

Katso IDs and authorisations cannot be used after 30 April 2021

Your Katso authorisations will not be automatically replaced with Suomi.fi authorisations. If you are still using Katso authorisations to manage someone else’s tax matters, you must request new Suomi.fi authorisations. Remember to reserve enough time for submitting and processing the request.

When using your Suomi.fi authorisation, log in to e-services with your personal e-bank codes, a mobile certificate or a certificate card.

You can authorise an agent to take care of your personal tax matters or your company’s taxes on your behalf. Your agent can be another person or a company, such as an accounting firm.

You do not need an authorisation to take care of your underaged child’s tax matters. Also, if you are your company’s managing director, you can take care of the company’s tax matters without an authorisation.

You can grant an authorisation on Suomi.fi. Corporate taxpayers can also use Katso authorisations until 30 April 2021. However, please note that old Katso authorisations are not automatically replaced with new Suomi.fi authorisations.

Suomi.fi authorisations for all tax matters

There are several different authorisations for tax affairs:

The “Managing of tax affairs” authorisation corresponds to the “MyTax for individuals and entrepreneurs” and “Company MyTax” Katso roles.

An authorised agent can take care of all the tax matters of the person or company who has granted the authorisation. The agent can also access tax data in MyTax. For example, an accountant can be authorised to manage all the tax matters of a company.

The authorised agent can visit tax offices and call our telephone service as well as use MyTax, Ilmoitin.fi, Lomake.fi and any future e-services on the authorising party’s behalf. However, the authorisation does not allow the agent to use Palkka.fi or to submit reports to the Incomes Register. The Incomes Register requires separate authorisation. The “Managing tax affairs” mandate is not available in the EMCS and Excise Duty Online e-services.

The “Managing of tax affairs” authorisation can be used by

  • individual taxpayers
  • self-employed individuals and agricultural operators
  • general and limited partnerships
  • limited companies, housing companies and cooperatives.

How to grant an authorisation – see instructions for your situation

Agents can see the personal tax data of self-employed individuals and agricultural operators

If you grant the “Managing of tax affairs” authorisation to an accounting firm, the firm can see your personal tax details as well as your company’s details in MyTax.

The agent can access the following details in MyTax:

  • income tax, inheritance tax, gift tax
  • advance rulings, claims for adjustment and decisions relating to income tax
  • decisions on claims for adjustment made by the Tax Administration and the Adjustment Board
  • letters and decisions concerning taxation
  • tax audit reports concerning business operations
  • decisions on advance rulings made in MyTax.

Inside information according to the EU regulation on market abuse is not available in MyTax.

Please note that your agent cannot change your company’s bank account number in MyTax with the “Managing of tax affairs” authorisation if the company form is limited company, public limited company or non-profit association.

The “Managing of tax affairs” authorisation allows you to search the tax debt register for business operators’ tax debt details. You can search for the tax debt details of companies and organisations without authorisation.

Suomi.fi authorisation for individual tax matters

The “Managing matters related to real estate taxes” authorisation corresponds to the “Filer of real estate details” Katso role.

The agent can view and update the real estate details used as basis for the authorising party’s real estate taxation. The agent can also request extended time for filing a real estate tax return and file a claim for adjustment of real estate tax.

You can search for the tax debt details of companies and organisations without authorisation.

The agent can use Lomake.fi and Ilmoitin.fi to file tax returns.

However, this authorisation does not allow the agent to use MyTax and access the authorising party’s tax data there.

  • Chairman of the Board
  • liquidator
  • Building Manager
  • entrepreneur (no listing in Trade Register required)
  • general partner or partner

The following parties can grant authorisations on the behalf of a company:

  • chairman and a member of the Board together, in accordance with the representation rule entered in the trade register
  • two members of the Board together, in accordance with the representation rule entered in the trade register

Limited companies and housing companies can authorise another person or company in the Suomi.fi service to take care of their tax matters even if multiple people together have the right to sign for the company. In other words, a limited company or a housing company can grant Suomi.fi authorisations even if the Trade Register records show that two or more people together sign for the company.

Authorisations can be granted on Suomi.fi if the company’s articles of association state that the following parties have the right to sign for the company:

  • the Board of Directors of the limited company or housing company, all together
  • members of the Board of the limited company or housing company, two together
  • the chairman together with one member of the Board.

Multiple persons entitled to sign for the company can grant an authorisation together if the right to sign for the limited company or housing company is recorded in the Trade Register and the persons granting authorisations have Finnish personal IDs.

Grant an authorisation as a company or an organisation (Suomi.fi)

You must request a Katso authorisation from your new clients regardless of their company type. Direct access to Tax Administration services through Tyvi service channels still requires Katso authorisation. This will change in 2020. More details on the schedule will be published during 2020.

Suomi.fi authorisations are only accepted in situations where the accounting firm does not have direct access to the Tax Administration from software, but instead uses MyTax for filing tax returns or uses Ilmoitin.fi to upload files generated by their accounting software.

If you are a private guardian, you cannot use MyTax or the Tax Administration’s other e-services on behalf of the individual under your guardianship unless they can use electronic identification and grant you the authorisation to do so. 

Go to Suomi.fi for more information on when you can and cannot act on behalf of someone else

Example: I own a forestry partnership together with my three siblings. Previously, my siblings had granted me a Katso authorisation that I could use to file the partnership’s tax return and VAT return online. Until now, I have used my Katso ID to log in to MyTax.

What do I do if I can no longer use Katso?

Do the following to continue using MyTax next year:

  1. Request a right to grant authorisations.
    Start by requesting an authorisation on Suomi.fi. In your request, you must state all the matters for which you require an authorisation, such as taking care of your forestry partnership’s tax matters.

    Your siblings must also sign the request. In addition, you will need copies of your and your siblings’ Finnish ID cards or passports as well as a document proving that the signatories have the right to sign for the partnership (such as a copy of a tax decision).

  2. Grant authorisation for managing tax matters.
    When you are notified that the right to grant authorisations has been registered for you, log in to the Suomi.fi e-authorisation service with your personal online banking codes. Select “Act on behalf of a company” to see the partnership. Authorise yourself to take care of the forestry partnership’s tax matters. Select the authorisation for managing tax matters.

For the Incomes Register, select the authorisation for reporting earnings payment data.

After the accounting firm has been authorised to take care of your association’s tax matters and Incomes Register reporting, they can use MyTax, Lomake.fi, Ilmoitin.fi and the Incomes Register on the association’s behalf. The accounting firm may also request a right to grant authorisations, which you can accept in the Suomi.fi e-authorisation service.
