saasman what is the context when I said 0% dividend
regarding Dividend: It depends on the withholding agent(payer) He may consider your Apk-Saas-ebook... as Dividend and for that reason, he may withhold 30% of the income as taxes
In this case, there is a tax treaty between Morocco and US that allows you to claim 15% instead of 30% so you have to file form W8-BEN and send it to the payer to claim 15%.
