Overseas financial account disclosures totaled KRW 107.1 trillion in 2026. Adding KRW 3.8 trillion in overseas trusts, which were reported for the first time this year, brings the reported overseas-asset total to approximately KRW 111 trillion. The figures announced by the National Tax Service show the results of reporting assets held overseas and should be distinguished from the total overseas net assets held by Korean residents and corporations.
Key changes
Overseas financial account disclosures increased 13.3% from KRW 94.5 trillion the previous year to KRW 107.1 trillion. The number of filers rose 9.1% year over year to 7,484.
Overseas stock disclosures totaled KRW 61.3 trillion, representing 57.2% of overseas financial account disclosures. This was the largest amount ever recorded, increasing by KRW 13.2 trillion from KRW 48.1 trillion the previous year.
The expansion of overseas stock disclosures was the main driver of the increase in overseas financial account disclosures.
Current status
The National Tax Service primarily attributed the increase in overseas stock disclosures to the expansion of Korean companies’ overseas operations, which led to additional stock listings and higher valuation amounts. Therefore, the increase cannot be conclusively attributed only to individuals’ new purchases of overseas stocks.
In the first overseas trust reporting conducted this year, 1,286 people reported 1,591 cases totaling KRW 3.8 trillion. Corporations accounted for 81% of the reported amount.
| Category | 2026 disclosure result |
|---|---|
| Overseas financial accounts | KRW 107.1 trillion |
| Overseas stocks | KRW 61.3 trillion |
| Overseas trusts | KRW 3.8 trillion |
| Total | Approximately KRW 111 trillion |
Impact
Whether an overseas financial account must be reported is not determined solely by whether someone holds overseas stocks. A resident or domestic corporation becomes subject to reporting in the following year if the combined balance of their overseas financial accounts exceeded KRW 500 million on any one day at the end of a month during the relevant year.
Overseas stock holders should therefore separately check their account balances, resident or domestic-corporation status, and any exemption requirements. Disclosure amounts may be affected by account-balance valuations and exchange rates, so they should not be interpreted as equivalent to the original investment amount or net assets.
Next verification point

- Overseas stock disclosures totaled KRW 61.3 trillion, accounting for 57.2%.
- Overseas trusts totaling KRW 3.8 trillion were reported for the first time in 2026, bringing the combined amount of the two items to approximately KRW 111 trillion.
