The deadline for the 2026 regular reporting of overseas assets, aimed at enhancing the transparency of offshore asset investments by residents and domestic corporations, is fast approaching on Tuesday, June 30.
This reporting requirement applies to taxpayers whose aggregate balance of foreign financial accounts (including virtual asset accounts) exceeded 500 million KRW on the last day of any month during the year 2025. In particular, starting this year, the obligation to submit details of "overseas trusts" established or maintained overseas is being implemented for the first time. As a result, residents and domestic corporations acting as grantors (settlors) must report all relevant information without omission, regardless of the trust amount, requiring special attention.
Following the submission deadline, tax authorities plan to conduct high-intensity, precise verifications of suspected non-reporters by linking cross-border financial information exchange data with foreign exchange data. Failure to report within the statutory deadline or underreporting will result in an administrative penalty of up to 10% of the non-compliant amount, and additional penalties may be imposed for failure to substantiate the source of funds. Furthermore, if the unreported amount exceeds 5 billion KRW, severe sanctions will apply, including criminal prosecution under the Punishment of Tax Offenses Act and public disclosure of the violator's identity. Therefore, proactive risk management is essential.
