Limited companies, housing companies, cooperatives, limited partnerships and general partnerships: how to grant an authorisation for tax matters
You can represent the company or cooperative without authorisation if your official role in the organisation (such as CEO) has been recorded in the Trade Register.
If you want to authorise an agent to represent the company or cooperative, you can grant an authorisation in the Suomi.fi e-authorisation service. You can also use Suomi.fi to request authorisations for taking care of other parties’ tax matters. Instructions on Suomi.fi: Request a mandate as a company or an organisation
You will need personal online banking codes, a mobile certificate or a certificate card for granting authorisations and using e-services.
How to grant an authorisation on Suomi.fi
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.
You will be able to select the authorisation later in the Suomi.fi e-authorisation service.
Grant an authorisation on Suomi.fi
Log in to Suomi.fi with your personal online banking codes or by another identification method and grant the authorisation in the e-service.
After you have granted an authorisation on Suomi.fi, it will enter into effect immediately. The authorised party can then log in to MyTax with their personal online banking codes and take care of the authorising party’s tax matters there.
Please note: An authorised agent cannot change a limited company’s or public company’s bank account number in MyTax. Only a representative of the company or cooperative, with an official role recorded in the Trade Register, can change the bank account number.
