## Introduction: Residency, Exit Tax, and Entity Tax Risks
South Korea imposes **exit taxes** (국외이주세) when certain residents cease to be tax residents, especially HNWIs holding large foreign-invested companies or assets. Combined with entity setup choices, governance and structure play a key role. Though no major exit tax announcements have been published in the last 30 days, current rules require careful attention to residency and shareholding thresholds.
## Key Rules on Exit Tax and Residency
- A **resident individual** who departs Korea for more than **180 days abroad**, or who registers foreign residence with the foreign authorities and deregisters domestic domicile, may be treated as ceasing residency for tax purposes. Under such exit, unrealized gains on **foreign shares** (over certain thresholds) are taxed.
- Entities: owning or controlling more than **1 billion KRW in foreign share value** or owning over **5% shareholding** in a foreign corporation can trigger exit tax. Documentation and valuation are critical.
## Entity Setup Options for HNWIs and Digital Nomads
| Structure | Benefits | Pitfalls / Exit-Tax Triggers |
|---|---|---|
| **Domestic corporation (법인)** | Favorable corporate tax rates, easier local operations, clear nexus for deductions | If control shifts overseas or owner moves abroad, exit tax may apply on unrealized gains in foreign assets owned within the entity. |
| **Foreign holding company** | May defer local taxes if structured correctly, possibly better asset protection, easier cross-border investment | With Korea’s exit rules, owning foreign company shares may still be taxed; line between foreign structure and control can be thin. |
| **Trusts / foundations** | Can aid in succession planning, privacy, possibly estate duties | Korean tax law increasingly scrutinizes beneficial ownership; trusts controlled remotely may still generate tax exposure. |
## Planning Strategies
- Time the migration: If you plan to establish foreign domicile or move abroad, consider completing major sales or transactions *before* departing to avoid exit tax on hidden gains.
- Maintain accurate valuations of foreign shareholdings, ideally using audited or recognized market values.
- Use treaties to determine tax residency status and any exit tax reliefs. Document physical presence, tax home, ties to Korea.
- Seek expert legal opinions when structuring entities: rules differ sharply depending on thresholds—1 billion KRW or more in foreign shares, or 5% ownership in certain foreign entities.
## Example in Practice
- A digital nomad resident in Korea, owning 10% of a foreign tech startup valued at 2 billion KRW. Moving abroad in 2027 would trigger exit tax on unrealized gain of that shareholding unless the shares were transferred or sold prior to departure.
- A foreign entrepreneur setting up a domestic Korean corporate vehicle for managing operations in Asia should structure share classes, local board control, and choose location of governance carefully to avoid unexpected tax residency or exit triggers.
## Key Resources and Next Steps
