South Korea: Crypto Accounts on Bankrupt Overseas Exchanges Still Must Be Reported
Key Takeaways
- •South Korean residents must report overseas crypto exchange accounts even if the platform has entered bankruptcy proceedings.
- •The reporting obligation is based on the account's reported balance rather than on whether the exchange can process withdrawals.
- •Reporting is required when combined overseas account balances exceed the applicable threshold on at least one day during the year.
- •The collapse of exchanges such as FTX in 2022 left many South Korean investors with assets frozen during lengthy insolvency processes.
- •Investors should retain account statements, bankruptcy notices, and transaction records as evidence supporting reported balances.
South Korea's tax authority has clarified that residents may still be required to report accounts held with overseas cryptocurrency exchanges even after those platforms have entered bankruptcy proceedings.
The National Tax Service stated that overseas virtual asset accounts remain subject to the country's overseas financial account reporting rules. The obligation applies even when an exchange has ceased operations and customers can no longer freely access their assets.
The clarification adds a further compliance concern for South Korean crypto investors who still have funds tied up in failed overseas platforms. The question has taken on practical weight in recent years as a series of high-profile exchange collapses — most notably FTX in 2022 — left customers worldwide, including in South Korea, with assets frozen during lengthy insolvency proceedings.
Reporting Rules Cover Crypto Assets
South Korea requires residents to report overseas financial accounts when their combined balances exceed the applicable threshold on at least one day during the year. These rules explicitly include accounts used for cryptocurrency trading.
Under the tax authority's position, an exchange's bankruptcy does not automatically remove the account from the reporting framework.
For investors, the situation can become complicated when they are unable to withdraw or transfer their assets. However, the reporting obligation centers on the overseas account and its reported balance rather than on whether the exchange is currently able to process withdrawals.
South Korea has continued to tighten oversight of overseas cryptocurrency activity. The National Tax Service has said that cryptocurrency holdings accounted for a significant portion of the assets reported through the overseas financial account system.
Compliance Pressure Grows
The clarification comes as South Korea expands its monitoring of digital assets and cross-border transactions. Recent regulatory changes have also strengthened customer identification and anti-money-laundering requirements for virtual asset businesses, and under the Act on Reporting and Using Specified Financial Transaction Information, crypto service providers have been brought within the country's anti-money-laundering framework.
The latest guidance underscores a broader principle for investors: financial difficulties at an overseas exchange do not necessarily erase domestic reporting responsibilities.
As a result, investors with assets trapped on bankrupt platforms may need to retain account statements, bankruptcy notices, transaction records, and other evidence supporting their reported balances.
The issue is particularly relevant for customers of failed exchanges who may assume that inaccessible assets no longer count. South Korean authorities appear to be adopting a more formal approach, requiring taxpayers to address such holdings through the existing reporting system.
