## Overview of Overseas Financial Accounts & Trusts Reporting
South Korea’s recent tax guidance clarifies obligations under the 2026 overseas financial accounts and overseas trust reporting regimes. Residents and domestic legal entities may need to report accounts or trusts depending on value thresholds.

### Who Has to Report?
- Residents and domestic legal persons whose **aggregate balances** of overseas financial accounts exceed **KRW 500 million** (approx) on any day in 2025. ([nts.go.kr](https://www.nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2201&nttSn=1352026&utm_source=openai))
- “Residence” includes long-term residents; certain foreign nationals and overseas Koreans may be exempt under conditions, especially if they were outside Korea for certain periods. ([nts.go.kr](https://www.nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2201&nttSn=1352026&utm_source=openai))
- Also, overseas trusts owned or benefitting residents that meet reporting criteria must be disclosed. Requirements for trusts begin for holdings “from assets held in overseas trusts from 2025 onwards” for reporting by residents.

### What Must Be Reported & When
- Submit via **HomeTax (홈택스)** or by paper to your local tax office. ([nts.go.kr](https://www.nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2201&nttSn=1352026&utm_source=openai))
- Deadline for 2025 holdings: typically **June 30, 2026** for overseas financial accounts. Apply similar schedule for trusts as specified in law. ([nts.go.kr](https://www.nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2201&nttSn=1352026&utm_source=openai))
- Types of reportable assets include bank accounts, securities, bonds, virtual assets, insurance, funds, etc. ([nts.go.kr](https://www.nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2201&nttSn=1352026&utm_source=openai))
- Penalties: non-reporting or mis-reporting leads to fines, including **10% of under-reported amount** (up to limit), public disclosure if exceeding large amounts, possibly criminal penalties. ([nts.go.kr](https://www.nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2201&nttSn=1352026&utm_source=openai))
## Planning for Compliance
1. **Maintain good records**
Track statements monthly, convert foreign currency & foreign asset values properly.
2. **Evaluate residency status carefully**
Some foreign nationals or overseas Koreans may avoid reporting if abroad for long periods or if they’ve never been residents for a certain duration.
3. **Coordinate with foreign tax reporting regimes**
If assets are in multiple countries, ensure consistent disclosure to avoid double penalties.
4. **Plan large transfers**
Shifting assets or trusts into Korea after 2025 may bring future reporting obligations; consult tax counsel ahead of time.
## Example Cases
- **Resident D** holds foreign brokerage, crypto, and bank accounts balancing KRW 600 million on some days in 2025: must report overseas financial accounts and trust details in 2026 submission.
- **Resident E** with a family trust overseas setup in 2024 used mainly for estate planning: assets held in trust from 2025 must now be reported.
## Tips to Avoid Risk
- Use professionals to prepare foreign asset disclosures—errors are costly.
- File early with provisional values if needed, then submit revisions if adjustments come after valuation.
- Keep copies of exchange rates, bank statements.
Adhering to overseas accounts and trust reporting is non-negotiable compliance territory. Misses are investments that cost large penalties. Stay proactive.
