## New Rules Around Foreign Asset & Trust Disclosure
The NTS has stepped up enforcement and reporting requirements for overseas assets under several recent announcements:
- In **September 2026**, it was revealed that Korean residents and domestic entities reported **over KRW 111 trillion** in overseas financial accounts and trusts—an all-time high. This included **first-time reporting of foreign trusts** (over 1,200 individuals) totaling KRW 3.8 trillion in assets.

- A **whistleblower reward regime** (포상금 제도) has been expanded: reports on offshore financial account non-compliance can earn **up to KRW 2 billion**, and combined with other rewards like for undeclared trust assets, possibly more. Non-reporting penalties are also significant. ([nts.go.kr](https://www.nts.go.kr/nts/na/ntt/selectNttInfo.do?bbsId=1028&mi=2201&nttSn=1352026&utm_source=openai))
- The **Crypto Asset Reporting Framework (CARF)** will be implemented in 2027, enabling automatic exchange of transaction data for crypto assets. This will strengthen verification of resident/non-resident crypto gains and overseas crypto exposures.

## Who is Affected
- Any **resident** (개인 or corporate) who holds foreign financial accounts (banks, securities, insurance, crypto) whose aggregate balance exceeds **KRW 500 million** at *any point in a month*.

- Those with **foreign trusts** where the settlor (위탁자) is a resident or domestic company and has control or beneficial interest in trust assets. ([nts.go.kr](https://www.nts.go.kr/nts/na/ntt/selectNttInfo.do?bbsId=1028&mi=2201&nttSn=1352026&utm_source=openai))
## Penalties and Incentives
- **Penalties** for non-reporting or false reporting can be large: overseas financial account or trust non-compliance can draw **fines, additional assessments**, or even criminal consequences depending on the amount and willfulness. ([nts.go.kr](https://www.nts.go.kr/nts/na/ntt/selectNttInfo.do?bbsId=1028&mi=2201&nttSn=1354611&utm_source=openai))
- Rewards for whistleblowers: 5-15% of penalty or fine, up to **KRW 2 billion** for major violations involving overseas financial accounts. For trusts and larger schemes, higher tops may apply. ([nts.go.kr](https://www.nts.go.kr/nts/na/ntt/selectNttInfo.do?bbsId=1028&mi=2201&nttSn=1352026&utm_source=openai))
- Reduced penalties if voluntarily disclosed or corrected before being audited—e.g., late or modified reporting may see **90%-30% penalty relief** depending on how far past deadline. ([nts.go.kr](https://www.nts.go.kr/nts/na/ntt/selectNttInfo.do?bbsId=1028&mi=2201&nttSn=1354611&utm_source=openai))
## Exit-Style Triggers / Restructuring Risks
- Even though Korea does **not yet have a formal “exit tax”** for HNWIs emigrating or renouncing residency, the new overseas asset reporting rules and CARF create **similar risks**:
* Verified data from abroad may expose previously undisclosed assets or gains.
* Foreign trusts, if linked to domestic control, may be taxed or assessed on disguised transfers.
- Entities or trusts structured outside Korea but controlled by Koreans will come under scrutiny; transfer pricing, beneficial ownership, and substance rules will matter more.
## What You Should Do Now
- Catalogue all foreign accounts, assets, and trusts. If over the thresholds, prepare disclosure filings (해외금융계좌 신고 / 해외신탁 신고).
- Work with legal/tax advisors to review trusts and ownership structures: establish whether you're the settlor, beneficiary, or controller.
- For those considering migration or dual residency, plan before you move. Document valuation and ownership at key cutoff dates.
- If you suspect you may be out of compliance, consider voluntary disclosure options to minimize penalties.
## Example
Resident B has two overseas bank accounts in different countries, holding balances: Account A: USD 2 million; Account B: USD 300,000. The combined value exceeds KRW 500 million pretty much every month.
- B must report the accounts by June 30, 2026, under 해외금융계좌 신고.
- Also, if B established a trust overseas and is the settlor or controls the trust, they must submit the trust’s detailed schedule by the same deadline. Missing either triggers penalties.
- If B comes forward voluntarily before enforcement, penalties might be reduced by up to **90%**, depending on how much time has passed and the nature of omission. ([nts.go.kr](https://www.nts.go.kr/nts/na/ntt/selectNttInfo.do?bbsId=1028&mi=2201&nttSn=1354611&utm_source=openai))
## Takeaway
While Korea’s legislative regime doesn’t currently impose a classic “exit tax” when a resident departs, the strengthened reporting obligations and automatic information exchange mechanisms make the possibility of retroactive exposure much more real. Early compliance, record keeping, and structural reviews are now essential for anyone with cross-border or crypto-heavy exposure.
