US ETF Tax Filing for Korean Investors | Dividends and Capital Gains

US ETF tax filing for Korean residents should be separated into dividends and realized gains. Dividends from US-listed ETFs such as SCHD, QQQ, VOO, and JEPI are generally paid after withholding tax. Gains from selling US ETFs may require Korean overseas stock capital gains tax filing.

The core rule is simple: dividends are taxed at payment, while realized sale gains must be checked annually.

1. Tax Categories

Tax rules can depend on personal circumstances. For large sales, use broker reports and consider professional advice.

2. Filing Checklist

• Download overseas stock capital gains reports from each broker
• Combine gains and losses across brokers
• Check realized losses as well as gains
• Review whether dividends affect comprehensive income thresholds
• Confirm KRW conversion and applied exchange rates

3. ISA and Pension Difference

ISA and pension accounts generally cannot buy US-listed ETFs directly. They use Korean-listed overseas ETFs, and the tax treatment differs by account type. Compare after-tax results, not only headline ETF returns.

4. FAQ

Do I separately file US ETF dividend tax?

Dividends are usually withheld at payment, but total financial income may still matter for Korean tax purposes.

If I do not sell, is there capital gains filing?

Usually no. Capital gains tax is based on realized gains from sales, not unrealized price increases.

What if I use multiple brokers?

You need to combine reports. A filing service from one broker may not include trades held elsewhere.
