The Tax Administration’s certificate service
The Tax Administration is developing a certificate service for managing interface applications and certificates electronically.
You need a certificate if you want to submit data or search for data through APIs.
Certificates are used to identify and authenticate the organisations that use an interface to report or retrieve data. They are also used to verify the integrity of records. The solution is based on digital certificates (Public Key Infrastructure).
The new service will not affect the existing and currently valid certificates. All existing certificates remain functional throughout their validity period.
Service launch schedule
The aim is to launch the new service during the spring 2024.
Deployment of the new service does not affect customers of the Finnish Tax Administration or Incomes Register at this point
Certificates for the interfaces of the Finnish Tax Administration and the Incomes Register are still ordered using the Incomes Register’s e-service:
Testing certificates for the interfaces of the Finnish Tax Administration and the Incomes Register are also ordered in the same way as before. See service-specific instructions:
The aim is that the customers of the Finnish Tax Administration and Incomes Register are transferred to the new service during the year 2024. After this, interface applications and certificates can no longer be managed in the Incomes Register’s e-service.
