You may be subject to other taxes outside of the witholding tax on dividends in the United States. In addition, you may be subject to taxes in your country on your investments. We aren't able to provide tax advice, as we are not tax advisors, so we recommend you seek the advice of a qualified professional. We provide to you a tax form, known as the 1042-S form, at the end of each year to help you to declare your taxes (if any). This can be found in the app under the Profile screen and by tapping on Reports.
