The Tax Administration’s certificate service

The Tax Administration is developing a certificate service for managing interfaces and certificates electronically.

You need a certificate if you want to submit or retrieve 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).

Schedule for introduction of the new e-service

Introduction of the new e-service will be carried out in two phases:

1. The production certificates section will be opened for users of the Tax Administration’s, the Incomes Register’s, and the Positive Credit Register’s interface on Wednesday, October 9, 2024, at 9 AM.
2. The test certificates section will be opened later (the schedule will be updated).

The new service will not affect the existing and currently valid certificates. All existing certificates remain functional throughout their validity period.
