The National Tax Service has released the results of the 2026 reporting of overseas financial accounts and foreign trusts. The combined declared amount of overseas assets reported by Korean residents and domestic corporations was KRW 111 trillion. This is a rounded figure combining KRW 107.1 trillion in overseas financial accounts and KRW 3.8 trillion in foreign trusts.
Key changes
The number of people and entities reporting overseas financial accounts rose 9.1% year over year to 7,484, while the declared amount increased 13.3% to KRW 107.1 trillion. In particular, declared stock holdings totaled KRW 61.3 trillion, accounting for 57.2% of the total declared amount for overseas financial accounts and representing the highest amount ever recorded.
The National Tax Service cited the expansion of Korean companies’ overseas operations, including listings on overseas stock markets and increases in valuation, as major reasons for the rise in declared overseas financial account amounts.
Current status
Foreign trusts were reported for the first time in 2026. A total of 1,286 people reported 1,591 cases worth KRW 3.8 trillion. The declared amounts for overseas financial accounts and foreign trusts are calculated separately and should not be double-counted when calculating the combined amount.
The criteria for reporting overseas financial accounts are as follows:
- A resident or domestic corporation whose total balance across overseas financial accounts exceeded KRW 500 million on at least one month-end date during 2025
- Those meeting this criterion were required to report their account information in June 2026
Foreign trusts are subject to separate filing requirements. Residents who maintained a foreign trust on at least one day during 2025 were required to submit details of the foreign trust by June 30, 2026. Domestic corporations were required to submit them within six months of the last day of the month in which their fiscal year ended.
Impact
The results show both the scale and composition of reported overseas assets. Stocks accounted for 57.2% of overseas financial account declarations, while the first application of the foreign-trust reporting system made the related filing volume separately identifiable.
However, merely holding overseas stocks does not mean that everyone is subject to reporting. Individual conditions—including whether the holder is a resident or domestic corporation, the form in which the account or trust is held, and the balance—must be reviewed. Failure to report overseas financial accounts or foreign trusts, or submitting an understated or false report, may result in administrative fines under applicable laws and regulations.
Next point of confirmation
To determine whether you are subject to reporting based on the 2026 results, you should review both the National Tax Service’s reporting criteria for overseas financial accounts and its filing requirements for foreign trusts. Because tax-reporting criteria and administrative fines may change when laws and regulations are amended, check the current official National Tax Service guidance again before filing or making a determination.
