The right answer depends on your tax exposure, hiring plans, and how long you intend to operate. Covers FDI notification (entity) vs. branch installation notification, how corporate tax/withholding/transfer pricing are handled, and when a branch is enough versus when you need a full subsidiary.
The core difference
| Item | Branch Office | LLC |
|---|---|---|
| Legal personality | None (an extension of HQ) | Yes (standalone entity) |
| Setup time | 6–12 weeks | 6–10 weeks to register (3–5 months to first revenue) |
| Governing law / filing | Foreign Exchange Transactions Act — branch installation notification to a foreign exchange bank | Foreign Investment Promotion Act — FDI notification (KRW 100M+ in foreign currency & 10%+ equity stake) |
| Minimum capital | None | No legal minimum, but KRW 100M+ if you want FDI recognition |
| Korean corporate tax | Korean corporate tax on income attributed to the branch (a separate branch tax can also apply) | Korean corporate tax rates apply |
| Transfer pricing exposure | Yes | Yes (needs to be managed separately) |
| Hiring | Possible | Possible |
| Independent contracting | Limited | Fully possible |
| Opening a bank account | Possible (stricter requirements) | Possible |
| Closing it down | Relatively simple | Requires a liquidation process |
The tax picture
A branch also files and pays Korean corporate tax on its Korea-source income. Because a branch has no separate legal personality, its results consolidate into the HQ's financial statements, and further settlement can occur in the HQ's home country via a foreign tax credit. Some tax treaties also impose a separate branch profit tax.
An LLC (standalone entity) is subject to Korean corporate tax rates — 9% up to KRW 200M of taxable income, 19% from KRW 200M–20B, 21% from KRW 20B–300B, and 24% above KRW 300B (as of 2025, plus a separate 10% local income tax). A 1-point increase in each bracket (to 10/20/22/25%) is scheduled starting the 2026 tax year, so confirm the current rate when you consult.
