To change your registration of reporting obligations or correct errors in the registration certificate, you must notify the Customs and Tax Administration within eight days of discovering the change or the error.  This is provided in section 1(7) of Executive Order on tax declaration and reporting etc. To do this, make the relevant changes to the registration of reporting obligations at www.virk.dk, which is a self-service platform operated by the Danish Business Authority.

If the business’ reporting obligation terminates, you must deregister the obligation. When you have made the changes or corrections, a new registration certificate will be generated.  Read more in section 1.10.1 For Danish businesses, and section 1.10.2 For non-Danish businesses.
