Tax & regulation
How do withholding taxes work for non-resident alien retail traders trading US equities?
By Easy Money Scanner · Educational reference · Not investment advice
The short answer
Non-resident alien investors trading U.S. equities generally are not subject to U.S. capital gains tax on most stock sale profits but are typically subject to a flat withholding tax on U.S.-source dividend income, often 30% absent treaty relief.
How it works
Applicable treaty rates between the investor's home country and the United States may reduce the standard withholding rate on dividends, requiring proper documentation such as Form W-8BEN filed with the broker.
An example
A non-resident alien from a country with a tax treaty reducing dividend withholding to 15% would need to file Form W-8BEN with their broker to claim that reduced rate.
Risk & limitations
Tax treatment for non-resident aliens depends heavily on individual circumstances, treaty status, and visa or residency classification; consult a qualified international tax professional. This describes U.S. federal rules only; Canadian and other non-U.S. investors are subject to different tax/regulatory regimes (e.g., CRA rules, TFSA/RRSP treatment) and should consult a local tax professional.
Examples are hypothetical, not trade recommendations. US contract and regulatory references do not automatically apply in Canada. Rules, margin requirements and broker policies can change; confirm them with the relevant authority and your broker.
