Because I'm not a US resident nor resident of a country with a tax treaty with the US, dividends paid to my positions have a 30% tax withholding to them. I'm considering putting a position on a country ETF but instead of using the underlying, using leaps on the ETF instead. I would sell a put option and buy a call of the same expiration (jan 2018) and strike price (effectively a synthetic long). I assume the dividend rate priced in options models take into account pre-tax (or very low tax) dividends. Is that assumption correct? Is there a flaw in this thinking? Capital gains are tax free and suffer no 30% withholding
