The tax withholding rate for international customers is determined by the tax treaty the United States has with your country. The withholding rate generally affects any sort of dividend or interest payment made the account, and it is immediately deducted upon payment. This deduction is listed as a line item in your history tab, as illustrated below.
The withholding rate assessed on your account is determined by your W-8 BEN during the application process. If you believe that the rate applied is incorrect, or if you have a special rate (Part II #10 of W-8 BEN, then you will need to re-submit a W-8 BEN to our accounts team. Please send your W-8 BEN that specifies your specific tax rate to our accounts team at firstname.lastname@example.org.
