## New Reporting Requirements for Overseas Financial Accounts
The Korean National Tax Service recently released its 2026 guidelines for **overseas financial account disclosure and overseas trust reporting**. Key aspects include:
- **Who must report**: Korean resident individuals and domestic corporations, plus certain foreign nationals/foreign-domiciled persons with substantial ties, including overseas trusts.([nts.go.kr](https://nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2201&nttSn=1352026&utm_source=openai))
- **Threshold**: If your **aggregate balance** in overseas financial accounts (including crypto accounts, stocks, deposits, insurance, etc.) exceeds **KRW 500 million** in any single month of the prior calendar year, you're required to report.([nts.go.kr](https://nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2201&nttSn=1352026&utm_source=openai))
- **When to file**: Reporting must be done during **June of the following year** — e.g. report 2025 holdings by June 30, 2026.([nts.go.kr](https://nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2201&nttSn=1352026&utm_source=openai))
- **Penalties**: Failing to report or under-reporting carries penalties — from fines (10% of undisclosed amount up to KRW 1 billion) to potential criminal liability depending on scale.([nts.go.kr](https://nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2201&nttSn=1352026&utm_source=openai))
## What Assets Need Disclosure?
- **Financial assets**: Includes foreign bank accounts, foreign listed/unlisted equities, bonds, crypto holdings located in foreign accounts or exchanges. Note: if price info unavailable, certain calculation assumptions apply.([nts.go.kr](https://nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2201&nttSn=1352026&utm_source=openai))
- **Foreign trusts**: Beneficiaries must report overseas trusts and associated accounts. Disclosure includes trust statements and asset balances.([nts.go.kr](https://nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2201&nttSn=1352026&utm_source=openai))
## Examples & Watch Points
- **Example**: Ms. Lee holds assets in a U.S. brokerage account, including stocks and a crypto exchange balance, which in aggregate exceed KRW 500 million in May 2025. She must report by June 30, 2026.
- Problem areas: using overseas wallet providers with thin records; delayed or missing statements; or misreporting the timing or currency conversion.
## Practical Compliance Tips
- Maintain monthly snapshots of all overseas accounts and asset values to track if the threshold is ever reached.
- Secure documentation showing closing balances, brokerage statements, exchange rates used. For crypto, ensure you get verifiable “price at month-end” if held overseas.
- Use electronic filing via **HomeTax or “손택스”**. There’s a “pre-fill” function that pulls previous year’s account details to ease filing.([nts.go.kr](https://nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2201&nttSn=1352026&utm_source=openai))
## Intersection with Entity Setup & Case Studies
- If you set up an offshore or foreign entity, both that entity and you personally may need to report its financials back to South Korea. Reporting needs to satisfy both **outward asset** and **trust/ownership** dimensions.
- Case study from similar jurisdictions suggests early coordination between legal and tax advisors to map all holdings, timing, and whether future changes (e.g. becoming nonresident) affect disclosure obligations.
Complying early can avoid fines or worse, and gives the chance to plan ownership and reporting structures more cleanly.
