Problems with signature validation in Denmark!

With the new version 1.5.3 of the regulation, the Danish authorities have fixed some problems with the validation of time zones and the signature.

Unfortunately, not all problems have been fixed and the validation software is also faulty. Extensive tests, which we have carried out with the latest officially provided validation script, have revealed this.

We are already in close contact with the authorities. We have not yet received a written response to our inquiry and the information about the errors.

We have also requested a written confirmation that the implementation and also the exported SAF-T files that we made until the regulation of March 2025 were correct, as we did not violate any regulation of the documentation.

In principle, the problems are as follows:

Correct times are recognized as incorrect during validation and incorrect times as correct. This is the result of our test with the new validation script.

The reason is very simple: The validation script simply cuts out the time zones in this case, but this is wrong.

We will now adapt the export to the new conditions with the next release. If there are any problems with the check in Denmark due to incorrect signatures, please contact us. We will clarify the issue with the authorities.
