Dual Residency Strategy

U.S. and Korean tax residency rules are completely different — and they often conflict.

It’s possible to be treated as a resident of both countries at the same time, triggering worldwide taxation in both jurisdictions.

Dual Residency Strategy helps you determine your true residency status under U.S. law, Korean law, and the U.S.–Korea tax treaty.

We clarify your obligations, reduce unnecessary taxation, and ensure you remain compliant in both countries.

Whether you are moving, working abroad, holding a green card, or maintaining ties to both countries, we help you navigate residency with confidence.

Clients often ask:

• “Am I a tax resident of the U.S., Korea, or both”
• “I live in the U.S. but still have a home in Korea — does that make me a Korean resident”
• “I have a green card but spend time in Korea — how does that affect my residency”
• “What is dual‑status, and does it apply to me”
• “How do I avoid being taxed twice on the same income”
• “How does the U.S.–Korea tax treaty determine residency”
• “What happens if my residency changes mid‑year”

These questions are extremely common — and the consequences of getting residency wrong can be significant.

We analyze your situation under both countries’ rules and build a residency strategy that minimizes tax exposure.
