You often have to do your first VAT declaration on paper. Sometimes you can do your first VAT declaration digitally. It may be that you do not see an assignment to submit your first declaration of your turnover tax in the digital portal of the Belastingdienst (Dutch Tax Authority) for entrepreneurs. In this case you often have to complete it via paper. You will receive a letter from the Belastingdienst by post to pay the declaration via paper.
Have you not yet received an envelope from the Belastingdienst to make a declaration on paper and can not do it through your digital portal? Then contact the Belastingdienst.
