Business owners who need to file an adjustment to their value-added tax return for 2019 or a value-added tax balance sheet item should do so before the first of April 2020 if they avoid being charged interest on outstanding tax. The designated supplementary tax return form(dutch) is downloadable from the Tax and Customs Administration’s web site. If the amount in question is less than 1,000 euros, it can simply be taken into account as part of the next regular turnover tax return.
