NTS targets multinationals and cross border risks while holding audit volumes steady and expanding litigation capacity

South Korea’s National Tax Service (NTS) on Monday unveiled its 2026 tax administration operating plan, pledging to secure stable revenue while tightening enforcement against high-value and cross-border tax risks, as the government faces mounting fiscal pressure. The NTS said it aims to collect about $265.2 billion (381.7 trillion won) in taxes this year, up about $13.3 billion (19.1 trillion won) from the 2025 supplementary budget, while maintaining the overall scale of tax audits at around 14,000 cases.

The plan includes the launch of a dedicated tax delinquency management task force in March, expanded litigation resources for major national tax lawsuits and intensified scrutiny of multinational firms suspected of offshore tax evasion. The NTS also outlined measures to build administrative capacity, including an artificial-intelligence roadmap for tax administration, integrated collection of non-tax national revenues and a new control tower to track virtual-asset transactions, while offering targeted relief such as payment deadline extensions and audit deferrals for small businesses and export-oriented firms.
