The disruption at Logius has now been resolved. The messages affected will now be resubmitted. This applies to tax returns and annual reports send to the Chamber of Commerce (KVK). We are still in contact with the Tax authority regarding possible leniency regarding the expiry of the submission deadline. We recommend that you check the returns to ensure that messages sent after 19:00 on 30 April and on 1 May have been successfully sent.
The SBU messages regarding postponement will also be resubmitted and / or retrieved. These do not need to be resubmitted to Logius, but will be handled automatically..
We are monitoring the submission of messages to Logius. This page will be updated as soon as more information becomes available.

Investigating
You may experience that messages to the Tax Authorities are rejected with an error message. The error message is: “The incoming message was signed with a token which was different from what used to encrypt the body. This was not expected”. This occurs when submitting income tax return, VAT return, Authorization and other messages. We are investigating this issue, and we will update this page as soon as more information becomes available. Our apologies for the inconvenience.
