Registration with the Dutch Tax and Customs Administration happens automatically when you enter your business in the Trade Register. The latter is necessary if your company has a permanent establishment in the Netherlands. If you represent a foreign company that is not registered in the Trade Register (i.e. no permanent establishment in the Netherlands), while performing services in the Netherlands that involve VAT, you must register at the Dutch Tax and Customs Administration yourself.
