Investing in U.S. Stocks Through a Foreign-Owned LLC

Owning U.S. stocks is not the same as running a U.S. operating business

Foreign investors often assume a U.S. brokerage account means U.S. business taxation. The IRS trading safe-harbor guidance says otherwise in many broker-only cases. But investment income categories such as dividends still have their own withholding rules.

This is why investors should separate the trade-or-business question from the withholding-on-income question.

Why dividends get special attention

Publication 515 explains that most U.S.-source income paid to foreign persons is subject to 30% tax unless a lower treaty rate applies. It specifically addresses dividend income, which is reportable for any amount and generally subject to 30% withholding unless treaty relief applies. So a foreign investor can have a relatively clean broker-only investment posture and still see withholding on U.S. dividends.

That is normal and should be expected.

What to review each year

Keep broker 1042-S or other withholding statements, dividend reports, and treaty documentation on file. If the investment activity sits inside a foreign-owned U.S. LLC, owner contributions and entity reporting should still be reviewed separately from the portfolio income itself.
