Self-employed individuals and operators of agriculture or forestry: how to grant authorisations
An agent can manage your tax matters on your behalf if you grant them the necessary authorisation.
Instructions on Suomi.fi:
- Grant an authorisation as a company or organisation
- Request an authorisation as a company or organisation
If you use Katso authorisations, note that the Katso service can no longer be used after 31 December 2020. Please start using Suomi.fi authorisations. Your Katso authorisations will not be automatically replaced with Suomi.fi authorisations.
Restrict what information your agent can see
If you grant your agent a Suomi.fi authorisation for tax matters, the agent can see, edit and file tax details related to your business activities and personal tax matters.
If you do not want your accountant or agent to see your personal tax data, do this:
- Go to Suomi.fi and grant your accountant an authorisation for specific tax matters. For example, the “Filing tax returns” authorisation allows your accountant to file all necessary tax returns on your behalf.
- Log in to MyTax with your personal e-bank codes, copy all the necessary details, and send them to your accountant.
Granting an authorisation with a Business ID: We recommend that you grant authorisations using your Business ID. In this way, your agent can access the taxpayer details in MyTax and will receive a summary once a month.
A self-employed individual can grant authorisations on Suomi.fi even if they are not in the Trade Register.
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Katso authorisations are no longer valid starting 1 January 2021.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.
