In this article, the author provides an overview of the Netherlands Dividend Withholding Tax Act 1965 (Wet op de dividendbelasting 1965, DWTA) and utilizes a number of examples to demonstrate whether or not, and to what extent, the DWTA is "EC proof". Given that the DWTA was substantially amended from 1 January 2007 to remove prohibited constraints following European Court of Justice (ECJ) case law, some landmark ECJ rulings are also discussed.
