Tax calendar
When is your OB return due?
Within fifteen days of the period (Landsverordening omzetbelasting 1999 art. 10; Algemene landsverordening Landsbelastingen art. 6 lid 2). If that day falls on a weekend or a Curaçao public holiday, it moves to the next working day.
This table is worked out with the same function as your return inside Bon Buku, and the same public holidays.
