South Korea’s National Tax Service said residents must report overseas financial accounts linked to foreign virtual asset exchanges even if the exchange has gone bankrupt, clarifying the treatment of customer accounts that later become bankruptcy claims.

The clarification came in response to a case involving a resident identified as Mr. A, who had held a balance on a foreign exchange that went bankrupt in November 2022. After the collapse, his account became part of the bankruptcy claims process. The tax agency said that if a resident holds an account opened with a foreign virtual asset provider for digital asset trading, the overseas financial account reporting obligation still applies even when that provider has entered bankruptcy.

Under Article 53, overseas financial accounts must be reported to the head of the tax office by June of the following year if the balance exceeds 500 million won. The NTS said digital assets were added to the reporting scope starting in 2023, bringing crypto accounts at foreign exchanges into the same disclosure framework as other overseas financial holdings.

The agency also disclosed aggregate reporting figures tied to overseas financial accounts containing digital assets. It said the reported scale of digital assets in such accounts was 10.5 trillion won in 2026, down 5.4% from the previous year. Individuals reported 9.8 trillion won, up 5.4%, while corporations reported 700 billion won, down 61.1%. The NTS attributed the overall decline to the impact of a broader price drop.

The guidance does not change the reporting threshold, but it closes a practical question for users of failed offshore exchanges: whether bankruptcy converts a reportable exchange balance into something outside the disclosure regime. The NTS position suggests the answer is no, at least where the resident still holds a claim connected to the foreign account.

Why It Matters

This clarification extends crypto compliance expectations beyond normal trading activity and into post-collapse scenarios. For users of offshore venues, insolvency is no longer a gray area for disclosure purposes, which could increase scrutiny around how foreign exchange accounts, frozen balances, and creditor claims are treated in tax reporting.

It also shows how digital assets are being folded into mainstream cross-border reporting rules rather than handled as a separate edge case. That matters for market structure because offshore exchange access remains common for crypto users, while tax and regulatory treatment is moving toward stricter alignment with traditional financial-account disclosure.
