South Korea’s National Tax Service ruled on Aug. 28 that residents must continue reporting qualifying cryptocurrency accounts held with bankrupt overseas exchanges, even when trading and withdrawals are unavailable.
Summary
- Korean residents must report qualifying overseas crypto accounts even when bankrupt exchanges block withdrawals entirely.
- Reporting applies when combined foreign account balances exceed 500 million won at any month-end annually.
- Affected taxpayers must submit declarations during June of the following calendar year to Korean authorities.
- Digital assets have been included in South Korea’s foreign account reporting regime since 2023 filings.
- Reported overseas digital asset holdings fell 5.4% to 10.5 trillion won in the 2026 disclosure cycle.
The National Tax Service issued its interpretation after a Korean resident asked whether an inaccessible exchange balance still qualified as an overseas financial account.
The taxpayer was a creditor of an overseas cryptocurrency exchange that entered bankruptcy in November 2022. The account holder could no longer trade or withdraw the assets and had entered the exchange’s distribution process.
The taxpayer was receiving partial bankruptcy distributions through a domestic foreign-currency account. However, the NTS concluded that the original overseas account remained subject to reporting because it had been opened with a foreign virtual asset service provider to trade digital assets.
The decision concerns disclosure obligations rather than whether the inaccessible assets generate taxable income. Reporting an account does not by itself establish that tax is owed on its entire balance.
The 500 million won threshold applies across accounts
Korean residents and domestic corporations generally must report when their combined overseas financial account balances exceed 500 million won, approximately $350,000, at the end of any month during the relevant calendar year.
Balances across qualifying foreign accounts are aggregated when applying the threshold. The rule can therefore apply even when no single account independently exceeds 500 million won.
Taxpayers must submit the report during June of the following year. The filing identifies the foreign financial institution, account information and reportable balance.
Digital assets were added to the foreign financial account regime beginning with the 2023 reporting cycle. Accounts held through overseas cryptocurrency exchanges can therefore qualify alongside foreign deposits, securities, funds and other covered financial assets.
Self-custody wallets are treated differently because they are not accounts opened with overseas virtual asset service providers. Crypto.news previously reported that decentralized wallets were excluded from overseas account declarations under the NTS interpretation.
The latest ruling clarifies that an exchange’s insolvency does not produce the same result. A customer can retain a reportable account or claim against the exchange even after losing normal control over the assets.
Bankruptcy creates a difficult valuation question
The NTS interpretation confirms that the account must be reported, but the publicly available summary does not fully explain how taxpayers should value a disputed or partially recoverable bankruptcy claim.
An exchange interface might display the customer’s original token balance even when the bankruptcy estate cannot return all assets. The value eventually distributed may differ substantially from that displayed balance.
The legal interpretation arose from a taxpayer already receiving partial distributions. It does not establish that every reported account balance will equal the amount recovered through bankruptcy.
Affected account holders may need records showing monthly balances, exchange statements, bankruptcy claims and distributions. Those documents can help establish what existed in the account and what was later recovered.
Exchange bankruptcy can leave customers waiting years for repayment. The FTX estate, for example, began a multibillion-dollar creditor repayment process after customers lost access to funds held on the platform.
The NTS ruling means Korean creditors cannot assume that frozen balances disappear from their disclosure obligations while those proceedings continue.
Overseas crypto disclosures fell to 10.5 trillion won
Korean taxpayers reported 10.5 trillion won in overseas digital assets during the 2026 disclosure cycle, according to figures attributed to the National Tax Service. The total declined 5.4% from the previous year.
Individual holdings increased 5.4% to 9.8 trillion won. Corporate holdings dropped 61.1% to approximately 700 billion won, producing the decline in the combined total.
The NTS attributed the overall reduction to a broad fall in asset prices. The figures represent balances disclosed through overseas financial account reports, not the full cryptocurrency holdings of every Korean resident.
South Korea’s total reported overseas financial accounts reached 107.1 trillion won in the latest cycle. The number of reporting individuals and companies rose 9.1% to 7,484, according to the published results.
The disclosure requirement is separate from South Korea’s planned tax on cryptocurrency gains. The country currently plans to apply a combined 22% tax to qualifying digital asset income from Jan. 1, 2027.
That future tax will also cover activity on overseas exchanges and private wallets. As crypto.news reported, annual gains above the 2.5 million won deduction would face a 20% national tax and 2% local income tax.
What affected account holders must do next
Residents whose combined overseas account balances exceeded the threshold during 2026 will generally need to file their disclosures in June 2027.
Customers of bankrupt exchanges should retain account records even if the platform no longer provides normal access. Bankruptcy notices, claim approvals and payment records may also be required to explain differences between reported balances and recovered funds.
The NTS is preparing broader enforcement tools ahead of the 2027 crypto income tax. In related coverage, the agency was reported to be developing wallet-tracing capabilities for overseas transactions.
South Korea also plans to exchange crypto transaction information with participating jurisdictions through the OECD’s Crypto-Asset Reporting Framework. The new data channels could make previously undisclosed overseas exchange accounts easier to identify.
