## What Is “Exit Tax” in Korea? (Domestic Outbound Reporting)
Although Korea does not use the term **“exit tax”** in exactly the same way as some jurisdictions (e.g. U.S. expatriate tax), it has instruments that essentially tax gains at or before departure:
- The domestic “**국외전출자의 양도소득세**” regime: If a **resident who qualifies as a “major shareholder (대주주)”** leaves the country under certain conditions, **unrealized capital gains** in domestic shares (and similar assets) are treated as though they were sold on the departure date and taxed accordingly. This applies only if certain criteria are met (domestic residency/ties, amount of share ownership, etc.).([nts.go.kr](https://www.nts.go.kr/nts/cm/cntnts/cntntsView.do?cntntsId=7821&mi=2355&utm_source=openai))
- For **real estate**, especially one-house setups under “海外移居法” (Overseas Relocation Act), there is a special non-tax or reduced tax regime when the entire household leaves and sells their single home within **two years** of departure. If conditions are met (whole household leaving, no other domestic property ownership, sale within 2 years), then **capital gains tax exemptions** may apply even if normal ownership or residency conditions aren’t met.([taxlaw.nts.go.kr](https://taxlaw.nts.go.kr/qt/USEQTA002P.do?ntstDcmId=010000000000048891&utm_source=openai))
## Eligibility & Key Conditions
| Policy | Who Qualifies | Key Conditions | Time Windows / Limits |
|---|---|---|---|
| 대주주 exit-share tax | Resident who is a major shareholder (상장/non-상장) leaving the country; has been domiciled for at least 5 of the past 10 years, owns enough shares to meet “major shareholder” thresholds | South Korean domestic shares/stockholding evaluated at departure | Departing before exit: unrealized gains taxed accordingly ([nts.go.kr](https://www.nts.go.kr/nts/cm/cntnts/cntntsView.do?cntntsId=7821&mi=2355&utm_source=openai))|
| 1-house overseas relocation special exemption | Korean resident owning only one home, whole household emigrates under Overseas Relocation Act, property sold within 2 years | No other domestic houses, property meets “single dwelling” definition | If sale happens after 2 years from departure, normal tax rules apply; high value homes (e.g. over KRW 600 million or 900 million depending on region) may still be taxable ([taxlaw.nts.go.kr](https://taxlaw.nts.go.kr/qt/USEQTA002P.do?ntstDcmId=010000000000073047&utm_source=openai))|
## Practical Examples to Avoid Surprises
- **Example A**: You own domestic shares worth KRW 2 billion and plan to become non‐resident. If classified as a “major shareholder,” the unrealized gain as of your departure date is taxed even if you don't sell. Avoiding this requires either divestment before meeting thresholds or timing exit carefully.
- **Example B**: You own one house in Seoul, very expensive (over the regional “high-value” threshold). You move abroad with your whole household and sell within 2 years. Under exception rules, you may qualify for full exemption if criteria are met. But if your house is “high-end” (eg above ₩600 million or ₩900 million depending on rules) it could be taxed even under exemption. Always check thresholds.
## Tips for Smooth Exit Planning
- Notify authorities and comply with **overseas relocation act** or equivalent laws, including filing “overseas relocation declaration” and **registering nonresident status** where needed.
- Secure a **“해외이주신고확인서”** from the Ministry of Foreign Affairs or relevant body — important for many exit or relocation tax exemptions.
- Hold off any sale beyond required timelines — if property or shares are sold after expiration of special windows (e.g. 2 years), full capital gains tax rules likely apply.
## Connections with Crypto Regime & Digital Nomad Life
- For cryptocurrency holdings, exit or becoming nonresident may trigger new tax implications — but under the crypto regime starting 2027, the taxation depends on transfers or disposals post-law rather than departure status per se. So **if you exit before realization**, unrealized gains may or may not be treated as taxable depending on domestic law around “주식” vs “virtual assets.”
- Digital nomads planning leave Korea should track both **residency status** and **ownership of domestic securities or real estate** prior to departure to mitigate EU-style exit tax exposure.
By understanding these rules well in advance, relocating can be done in a tax-efficient manner without unexpected liabilities.
