Forestry partnerships, agricultural partnerships, real estate partnerships, business partnerships: how to grant an authorisation for tax matters

You can authorise yourself or another person or company to handle the partnership’s taxes electronically. The instructions for authorising someone will vary for different categories of shareholders, and they may vary for other reasons, too.

Follow these steps if everyone among the partnership's shareholders can log in to the e-service, and they are citizens of Finland, and the partnership is for agriculture, forestry or real-estate holding.

Follow these steps if a business partnership, forestry partnership, agricultural partnership or a real estate partnership is concerned, and at least one of its shareholders is an estate of a deceased person, or at least one shareholder is a partnership itself, or if someone among the shareholders is unable to log in to the e-service.

You will need personal online banking codes, a mobile certificate or a certificate card for using the e-services.

If every shareholder can log in, and the partnership is for agriculture, forestry or real estate, do this:

The authorisation process also requires that all shareholders are citizens of Finland.

1

Select one or multiple authorisations

The “Managing of tax affairs” authorisation enables the authorised party to take care of all of the authorising party’s tax matters. Other authorisations only cover certain individual matters.

Read the authorisation descriptions to see which authorisation fits your needs

You will be able to select the authorisation later in the Suomi.fi e-authorisation service.

2

Give the authorisation

After you have logged in to the e-authorisation service in Suomi.fi, you can authorise the appropriate person. You can enter your personal e-bank codes to log in – or apply other methods. Remember to confirm that you have personally assigned the authorisation.

Have the other shareholders confirm it

Have the other shareholders confirm the authorisation you gave, by logging in to Suomi.fi e-Authorizations. Each one of them must log in independently, with their personal e-bank codes (or other methods of login).

After all of them have given their confirmations, the authorisation is validated. It cannot be be validated before.

The authorised person can then log in to e-services, including MyTax, with their e-bank codes and handle the partnership’s taxes there.

Request rights to grant authorisations

First, you must make a request for authorisation in the Suomi.fi e-authorisation service. The request can concern either a right to grant authorisations or a representative’s right to grant authorisations.

Request authorisations on Suomi.fi

Please note: After your request has been processed and your right to grant authorisations has been registered, you must log in to the Suomi.fi e-authorisation service with your personal online banking codes. In the service, you will be able to grant the actual authorisations (described in section 1) that will allow the party you authorise to take care of your tax matters electronically.

Grant an authorisation on Suomi.fi

After the request for authorisation has been accepted and you have received the right to grant authorisations, log in to the Suomi.fi e-authorisation service.

Grant the required authorisations to the parties you need to take care of the organisation’s tax matters. For example, you can grant an authorisation to yourself or to an accounting firm.

Frequently asked questions

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?
