Was looking at Euronav as a potential buy and saw that Belgium imposes a 30% withholding tax on the dividend, but there is a double tax treaty with HK that means the withholding should be reduced to 15%. Has anyone dealt with this situation via IBHK before - do you just ask them for the form to fill in and then they arrange to credit your account with the extra 15%? Or is it more complex than that?
