For non-US citizens engaging in stock trading within the United States, it's important to recognize that they are subject to U.S. tax laws. While non-resident aliens (NRAs) have certain exemptions, it's vital to understand the specifics to avoid potential penalties.
Types of Stock Trading Activities
Stock Purchase and Sale: When a non-US citizen purchases and sells stocks, they are considered to have engaged in a U.S. trade or business. This means that any gains from these transactions are subject to U.S. tax.
Foreign Stock Options: Non-US citizens who hold stock options in a foreign corporation, which are then exercised in the United States, are also subject to U.S. tax on the gains.

Consult a Tax Professional: Given the complexities of non-US citizen stock trading tax, consulting with a tax professional is highly recommended to ensure compliance with U.S. tax laws and optimize your tax situation.
