South Korea's Tax Authority Launches Special Audit of KB Kookmin Bank

South Korea's National Tax Service (NTS) has launched a special tax audit of KB Kookmin Bank amid suspicions of tax evasion, marking a rare instance of non-routine scrutiny for one of the country's largest commercial lenders.

Agents from Investigation Bureau IV of the NTS's Seoul Regional Tax Office arrived at KB Kookmin Bank's headquarters in Yeongdeungpo District, western Seoul, on Thursday to collect accounting records and other documents needed for the probe. The visit signals that authorities have moved beyond preliminary review and into an active investigation phase.

Investigation Bureau IV has earned the nickname "corporate grim reaper" in Korean business circles because of its role in handling irregular, non-scheduled audits, typically reserved for cases where authorities suspect deliberate wrongdoing rather than routine compliance checks. Its involvement, rather than that of a standard audit team, has drawn particular attention to the case.

The NTS has not disclosed the specific allegations driving the audit, and a spokesperson for the agency said it could not comment on details concerning individual taxpayers. KB Kookmin Bank has likewise not issued a public statement addressing the scope of the investigation.

According to the tax authority, the audit is expected to run through the end of the year, giving investigators several months to examine the bank's financial records. The extended timeline suggests the case could involve a detailed review of transactions rather than a narrow, isolated issue.

KB Kookmin Bank is the core banking subsidiary of KB Financial Group, one of South Korea's largest financial holding companies. Special tax audits of major banks are uncommon and can carry reputational and regulatory implications even before findings are made public, particularly for institutions central to the country's financial system.

The case adds to a string of recent tax-related actions by Korean authorities, including a joint operation with customs officials targeting delinquent taxpayers and a separate audit involving a well-known entertainer, underscoring the NTS's continued focus on enforcement across both corporate and individual filings.
