How it works (simple playbook):
- Open an overseas stock account with a Korean broker (e.g., Mirae Asset, Shinhan, NH, Kiwoom, KB, Samsung, Korea Investment). They support U.S. equities and walk you through the steps.
- Submit Form W-8BEN in your broker app so U.S. dividend withholding uses the treaty rate.
- Convert KRW→USD (inside the app) and place a buy order during U.S. market hours.
Tax + paperwork you should know:
- U.S. dividends paid by U.S. companies to Korean residents are generally withheld at 15% under the U.S.–Korea tax treaty (with W-8BEN on file).
- U.S. capital gains from selling U.S. stocks are generally not taxed in the U.S. for non-resident aliens (unless you’re in the U.S. ≥183 days that year).
- Korea taxes overseas-stock gains: after a ₩2.5M annual basic deduction, gains are typically taxed at an effective 22% (20% national + 2% local). You report/pay in May of the following year.
- If you keep money or securities at a foreign broker, and your overseas financial accounts top ₩500M on any month-end, you must file Korea’s Overseas Financial Account Report (June filing).
Bottom line: Yes—you can buy MSTR in Korea through any major domestic broker (or a foreign one that accepts Korean residents), just make sure your W-8BEN is set, and handle Korea’s capital-gains filing (and any overseas-account reporting) like a pro. 🚀
