Limited companies, housing companies, cooperatives, limited partnerships and general partnerships: how to grant authorisations
If you take care of your company’s taxes and you have an official role recorded in the Trade Register, you can manage your company’s tax matters without authorisation. You can log in to the Tax Administration’s e-services with your personal e-bank codes.
If you want to authorise an agent to manage your company’s taxes, do this:
Instructions on Suomi.fi:
- Grant an authorisation as a company or an organisation
- Request an authorisation as a company or an organisation
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.
If you use Katso authorisations, note that the Katso service can no longer be used after 31 December 2020. Start using Suomi.fi authorisations. The Katso authorisations will not be automatically replaced with Suomi.fi authorisations.
Two or more together signing for the company
A limited company or a housing company can grant an authorisation to an agent even if the Trade Register shows that two or more people together sign for the company.
The articles of association must specify one of the following signature rights:
- 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.
The right to sign for the limited company or a housing company must be recorded in the Trade Register and the persons granting authorisations must have Finnish personal IDs.
If you continue using Katso authorisation
Even though Katso authorisations will remain in use in 2020, we advise you to take Suomi.fi authorisations into use as soon as possible. Note that you will only be able to use the following Katso roles:
- Company’s Master User
- Company’s Parallel Master User
- Company MyTax
The following Katso roles have already been discontinued:
- Company's income tax returns
- Filer of self-assessed taxes.
Katso authorisations will be taken out of use
Katso authorisations are no longer valid starting 1 January 2021. If you are currently using Katso authorisations to take care of someone else’s tax matters, you must request new Suomi.fi authorisations instead. Your Katso authorisations will not be automatically replaced with Suomi.fi authorisations.
When using your Suomi.fi authorisation, log in to the e-service with your personal e-bank codes, a mobile certificate or a certificate card. The mobile certificate or certificate card can also be provided to you by an organisation.
