How to declare excise duties
You typically declare and pay excise duties once a month. There may be exceptions, which will appear in the information under the specific excise duty.
Almost all types of duties are declared via E-tax for businesses (TastSelv Erhverv) here at skat.dk. When declaring, you must have an overview to hand of what you need to declare. For example, your account of last month’s sales, an inventory count or similar.
