Death estates with a Business ID: how to grant a Suomi.fi authorisation for managing tax matters

An estate of a deceased person must always have a Business ID in order to authorise other individuals or companies to take care of the estate’s tax matters on its behalf. A death estate can get a Business ID only if the estate conducts business operations that require a Business ID.

At present, an estate that does not have a Business ID must use paper forms for its tax matters.

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