## Context: What Is Exit or “Exit-like” Tax in Korea?
Unlike some countries, **South Korea does not yet have a tax explicitly called an ‘exit tax’** in the legislative code that universally applies when a person emigrates. However, similar mechanisms exist—most notably the **국외전출자 주식등 양도소득세** (“capital gains tax on shares held upon the move overseas” for large shareholders).([nts.go.kr](https://www.nts.go.kr/nts/cm/cntnts/cntntsView.do?cntntsId=7821&mi=2515&utm_source=openai))
Also, authorities closely monitor overseas asset disclosures, trust structures, and undeclared accounts as part of cross-border enforcement. For HNWI, these intersect with potential exit tax liabilities.

## Triggers & Key Rules for “Exit-Tax-Like” Liabilities
| Trigger | What Happens / What You May Owe
|---------|------------------------------
| **Large shareholdings when emigrating** | If you're a resident holding **“대주주” (major shareholder)** status—based on share percentage or market cap—and you move your residence abroad, gains on your shareholdings as of the move date may be taxed.([nts.go.kr](https://www.nts.go.kr/nts/cm/cntnts/cntntsView.do?cntntsId=7821&mi=2515&utm_source=openai))
| **Residence status / duration** | To be subject, you usually must have been a resident of Korea for **at least 5 of the last 10 years**.([nts.go.kr](https://www.nts.go.kr/nts/cm/cntnts/cntntsView.do?cntntsId=7821&mi=2515&utm_source=openai))
| **Assets included** | Primarily **stock holdings**, especially in Korean firms or listed entities. Also, possibly overseas assets or crypto examined through international reporting if part of trust or joint ownership structures.

## Planning Strategies for HNWI
- **Timing emigration**: If possible, plan the date of moving abroad to optimize share valuations or avoid triggering majority shareholder status. For example, move in a year where share value is expected to dip, to reduce taxable base.
- **Hold shares via non-resident entity or trust**: In some jurisdictions, holding stock indirectly may help reduce direct exposure, but Korean law may require beneficial ownership disclosures—so work with legal counsel.
- **Consider early realization**: Selling shares or restructuring holdings prior to emigration can help lock in cost basis or limit exposure if exit-related tax kicks in.
- **Residency duration path**: If you have lesser than 5 years’ residency, moving before becoming “major shareholder” may reduce or avoid liabilities under the overseas share exit rules.

## Example Scenario
* You are a Korean resident, holding 3% of a public company (a 대주주) and you've lived in Korea 6 of the past 10 years. You plan to emigrate in mid-2027. At that point, Korean law treats your shareholdings as having been “disposed of” at fair market value, even if unopened. You’ll need to report and pay capital gains tax on that “deemed disposition.”
If instead you emigrated earlier or transferred your shares into an offshore vehicle properly structured and disclosed, you might reduce or defer those obligations, but risk of breach exists. Consulting with cross-border legal and tax experts is essential.

## Recent Policy Environment
- The 국외전출자 조세 (overseas expatriate share capital gains) rules remain active and enforced; residents are required to report shareholdings and may be taxed under these rules when they move abroad.([nts.go.kr](https://www.nts.go.kr/nts/cm/cntnts/cntntsView.do?cntntsId=7821&mi=2515&utm_source=openai))
- Clearer reporting around overseas trust and account rules means that hidden assets are more likely to be discovered; the risk for HNWI is increasing.

## Key Takeaway
While Korea doesn’t use the label “exit tax” broadly, its rules for large shareholders emigrating and its overseas asset disclosure regime function similarly. HNWI planning cross-border moves must consider shareholding status, asset types, and valuation timing to limit exposure.
