I am an F1 student (non resident alien) and have invested in a few stocks. My question is

1. Am I liable to pay capital gains tax, as a non resident alien? (What I heard was that non resident aliens do not pay capital gains tax)

2. If yes, do I have to pay quarterly estimated tax on realized gains?

Thank you in advance for your invaluable feedback.

Effone.

For a nonresident the capital gain on the sale of personal property (like stock) that is not effectively connected with a U.S. business is free of any tax. This personal property does not include gain or loss on disposing a U.S. real property inertest, which must be reported on schedule D (Form 1040).
First complete lines 89, 90 and 91 on page 4 of Form 1040NR. Now fill out the line 83.
