What it does

Return the Dutch VAT (btw) return and payment due date for a month, quarter or year (Belastingdienst page 'Wanneer moeten mijn btw-aangifte en betaling binnen zijn?', art. 19 AWR: last day of the month after the period; 31 March of the next year for an annual return), years 2000-2035: the published return_due is the safe deadline, atw_effective_due is the reading under the Algemene termijnenwet (next day that is not a Saturday, Sunday or art. 3 holiday) and is unverified for btw, and extra holidays set by decree (Atw art. 3 lid 3) are not included.
