Frequently Asked Questions
How much can I invest in US stocks?
There is no limit on the amount you can invest in overseas securities, as long as you properly report to the Bank of Korea. The $50,000 annual limit applies to general remittances, not to investment transactions that are properly reported through your designated foreign exchange bank.
Do I pay tax twice on US dividends?
No, the tax treaty prevents double taxation. The US withholds 15% on dividends. Korea then taxes the income but allows a foreign tax credit for the US tax paid. Effectively, you pay the higher of the two rates (usually Korean rate), not both added together.
Can I buy US real estate without visiting?
Yes, US real estate can be purchased remotely using power of attorney. Many Korean investors purchase sight-unseen using trusted agents. However, Korean FX reporting requirements still apply. All funds must flow through your designated bank with proper documentation.
What happens if I don't report overseas assets?
Penalties are severe. For unreported overseas financial accounts or assets, penalties can reach 10-20% of the unreported amount, plus potential criminal penalties for willful evasion. Korea also participates in CRS (Common Reporting Standard), so Korean authorities receive information about your overseas accounts.
Should I use Korean or US broker?
Depends on your situation. Korean brokers offer Korean language support and integrated tax reporting but have higher fees and limited product selection. US brokers like Interactive Brokers offer lower costs and full market access but require manual tax reporting. For larger portfolios (100M+ KRW), US brokers typically make more sense economically.
