Do I need to report taxes to the U.S. Internal Revenue Service?
If a valid W-8BEN is filed for the account, the U.S. IRS only withholds a small amount of tax on dividends received. The rate varies from country to country but it does not exceed 30%. Investors are responsible to report any capital gains or capital losses to your local tax authorities. However, a separate tax return is not required to be filed in the United States. A Form 1042 is mailed in April.
