More and more businesses and workers cross borders and have financial acitivities beyond the Danish borders. Often, this will have tax consequences. 

In Denmark, the Danish Tax Agency is constantly focusing on improving our guidance about Danish tax matters to make it easier to pay the correct amount of tax. Our efforts include participating in campaigns with other EU countries and cooperating with the individual countries for the purpose of helping each other and the businesses or workers crossing our borders.
