Yes, US tax law requires the withholding of tax for non-US persons (non-resident aliens) at a rate of 30% on payments of US source stock dividends, short-term capital gain distributions and substitute payments in lieu.

Consequently, all dividends of US-listed securities are subject to a 30% dividend withholding tax which will be deducted accordingly from your Brokerage account buying power after the dividends have been credited.

You can find dividend payment details, including any withholding tax deductions, in your monthly statements as well as Syfe Brokerage app (Account > My funds > Transfer history).
