Identification without Finnish ID - eIDAS identification for EU citizens
The Tax Administration's e-services require identification and authentication via a Finnish personal ID. However, some EU citizens can use their home country's national identification methods to access the services through eIDAS identification. The Tax Administration's e-services do not support eIDAS identification yet, but eIDAS users can fill in a service request form.
