Foreign Tax Credit Optimization

For U.S. taxpayers with Korean income — or Korean taxpayers with U.S. income — the Foreign Tax Credit (FTC) is the primary tool for preventing double taxation.

But the rules are complex, the limitations are strict, and many taxpayers lose credits simply because they were calculated or allocated incorrectly.

Foreign Tax Credit Optimization ensures that every eligible foreign tax is properly claimed, allocated, and maximized under U.S. law, Korean law, and the U.S.–Korea tax treaty.

We help you reduce your global tax burden while staying fully compliant.

Clients often ask:

• “I paid tax in Korea — why am I still paying tax again in the U.S.”
• “How do I know which foreign taxes qualify for the credit”
• “Why is my FTC limited or reduced”
• “How do carryovers work”
• “How do I apply the treaty to reduce double taxation”
• “How do I allocate salary or stock compensation earned in both countries”
• “What happens if I move mid‑year or become dual‑status”

These issues are extremely common — and the right strategy can significantly reduce your tax bill.

We analyze your income, residency, and foreign tax profile to maximize your allowable credits.
