For many organisations, now is the time to renew the certificate for the API ‒ some reminder messages have not been sent out

The certificates for the Tax Administration’s or the Incomes Register’s interfaces retrieved in 2022 will expire this year.

We recommend that you contact the supplier of your organisation’s payroll or benefit software system to discuss what needs to be done when a certificate is due for renewal. Because of the many differences between software products, the steps you need to take may vary.

A certificate is always valid for 2 years, after which it must be renewed. After expiration, you can no longer access the API to send data or retrieve data.

We will be reminding about certificate expiration 14 days in advance during July and August

The certificate’s technical contact person usually receives an email reminder 60 days before the certificate expires.

However, reminder emails about certificate expiration were not sent during the period from March 20 to July 3, 2024. The issue has now been fixed, and we apologise for any inconvenience this may have caused.

We will send a reminder today to the contact persons of the organisations whose certificates are expiring within the next 14 days. If you have already renewed the certificate, the message requires no action from you.

During July and August, the technical contact persons for the certificates will receive an extra reminder email 14 days before the certificate expires.

We want to ensure that as many organisations as possible notice and renew their certificates on time despite the missing reminder emails. If the certificate expires, please request a new certificate for your organisation in the Incomes Register's e-service.

Check when your organisation's certificate expires

The certificate can tell you when it expires and stops being active. Your supplier will explain how you can check the period of validity.

If you are using the Tax Administration’s or the Incomes Register’s interfaces, you can see the certificates of your organisation when you sign in to the Incomes Register’s e-service. You need to have an authorization for using the e-service.
