South Korea Mandates Reporting for Bankrupt Crypto Exchange Accounts

The ruling stems from a specific inquiry by a taxpayer who, despite being unable to access their funds on a failed exchange, continued to receive partial bankruptcy distributions through a domestic account. The NTS determined that because the initial account was established with a foreign virtual asset service provider, the disclosure obligation remains in force regardless of the platform's solvency status or the user's lack of control over the assets.

Under South Korean regulations, residents and domestic corporations must report all foreign financial accounts if their combined balance exceeds 500 million won—approximately $350,000—at the end of any month during the calendar year. While the NTS has clarified that these accounts must be reported, the agency has yet to detail how taxpayers should value disputed or partially recoverable claims. Account holders are advised to maintain rigorous documentation, including bankruptcy notices and distribution records, to substantiate their filings against the balances displayed on defunct exchange interfaces.

Digital assets were integrated into the foreign account reporting regime in 2023, though self-custody wallets remain exempt from these specific requirements. As the 2027 implementation of a broader 22% tax on cryptocurrency gains approaches, the NTS is signaling a more aggressive enforcement stance. The agency is currently developing sophisticated wallet-tracing capabilities and preparing to exchange transaction data with international partners via the OECD’s Crypto-Asset Reporting Framework to ensure comprehensive oversight of overseas holdings.
