## Understanding U-Turn and Exit Tax Rules in Korea
South Korea has specific obligations for **”국외전출자”**—locals or residents moving their tax residence overseas. If you're a **major shareholder (대주주)** in domestic stocks, upon exit you can be taxed on **unrealized gains** as if you sold your shares.([nts.go.kr](https://www.nts.go.kr/nts/cm/cntnts/cntntsView.do?cntntsId=7821&mi=2355&utm_source=openai)) You’re also required to report **domestic stock holdings** and appoint a **tax representative (납세관리인)** before departure.([nts.go.kr](https://www.nts.go.kr/nts/cm/cntnts/cntntsView.do?cntntsId=7821&mi=2355&utm_source=openai)) Failure to comply may lead to **evaluated penalties**.
## Recent Announcements Supporting Returnees (“U-Turn”)
In June 2026 the National Tax Service (NTS) launched **online 1:1 tax consultation** services for **repatriating Koreans abroad**. This aims to reduce uncertainties over tax on overseas income, transfer of foreign assets, and implications of moving home. The service starts in **July 2026**.([nts.go.kr](https://www.nts.go.kr/nts/na/ntt/selectNttInfo.do?bbsId=1028&mi=2201&nttSn=1352537&utm_source=openai)) This is part of the broader “세금수호천사팀 (K-Tax Angel)” program that also provides overseas tax lectures and tailored assistance.([b.nts.go.kr](https://b.nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2201&nttSn=1348553&utm_source=openai))
## Key Compliance Steps if You’re Returning or Exiting
- Before departure: File **stock ownership report** (domestic shares), deliver it to your tax office; appoint a **tax representative** if required. ([nts.go.kr](https://www.nts.go.kr/nts/cm/cntnts/cntntsView.do?cntntsId=7821&mi=2355&utm_source=openai))
- Be aware of **exit tax triggers**: If you meet major shareholder thresholds, you may need to pay “가상양도세” (deemed capital gains) on domestic stocks you hold. Examine thresholds carefully—ownership percentage, market value, etc.([nts.go.kr](https://www.nts.go.kr/nts/cm/cntnts/cntntsView.do?cntntsId=7821&mi=2355&utm_source=openai))
- For crypto or foreign assets: Know that gains derived from abroad may still be taxed upon becoming resident, especially under the new crypto tax regime starting 2027. Foreign bank or crypto accounts may be subject to **해외금융계좌 신고제도** (Overseas Financial Account Reporting) when crossing certain thresholds (e.g. aggregate assets over ₩500 million at any monthly-end) in any month.([nts.go.kr](https://www.nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2201&nttSn=1352026&utm_source=openai))
## Penalties & Reporting Timeframes
- **Stock holdings report** and tax representative designation must be completed **before departure**. If not, penalties apply.([nts.go.kr](https://www.nts.go.kr/nts/cm/cntnts/cntntsView.do?cntntsId=7821&mi=2355&utm_source=openai))
- **Exit tax (양도소득세 at exit)** must be filed & paid within **3 months** of month-end after departure. Deadlines are tight.([nts.go.kr](https://www.nts.go.kr/nts/cm/cntnts/cntntsView.do?cntntsId=7821&mi=2355&utm_source=openai))
- Overseas financial and trust accounts must be reported by **June 30** of the following year for accounts held during any reporting-year you were resident.([nts.go.kr](https://www.nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2201&nttSn=1352026&utm_source=openai))
## Scenario Example
- **Choi**, a resident in Korea, intends to leave the country permanently. He owns 10% shares in a Korean listed company valued at ₩5 billion. Under the exit rules, upon exit he may be taxed on the unrealized gain of these shares without a sale. He must file his holdings, appoint a representative, and settle “exit tax” within the required timeframe.
- **Lee**, a Korean U.S. resident returning home after several years. She holds foreign assets and crypto. She is subject to overseas account reporting if in 2025 she had overseas financial/crypto accounts whose **monthly-end total exceeded ₩500 million** in any month. She also benefits from NTS’s U-Turn online consultation service starting July 2026 to understand how to report foreign income, trusts, or gifts.
## Actionable Checklist Before Moving
1. Check if you meet the **major shareholder** criteria. If yes, calculate your potential exit tax.
2. Gather documentation for any foreign financial accounts or crypto holdings you own abroad.
3. Before leaving: file required reports, nominate tax representative, understand payment deadline.
4. Use the NTS *online 1:1 U-Turn service* for bespoke advice.
5. Follow crypto cost basis rules—if you hold before 2027, decide whether to realize gains now or later (see Article 1 above).
**Bottom line:** South Korea is tightening exit and U-Turn compliance. But with new services and clear rules, returnees and departing residents can reduce surprises if they plan carefully.
