If you live in the Netherlands, you must state your complete worldwide income in your tax return. The fact that you have to state your income from abroad does not always mean that you have to pay income tax on this in the Netherlands; a special scheme ensures you do not have to pay double income tax. You can find more information about this on the site of the Belastingdienst.

If you have income from the former Netherlands Antilles and Aruba, you must consult the Tax Regulations for the Kingdom (Belastingregeling voor het Koninkrijk). There is a separate regulation for Bonaire, Sint Eustatius and Saba.
