South Korea: National Tax Service Enhances Cross-Border Virtual Asset Income Reporting Under Notice 26-015

Published 24 July 2026, Notice 26-015 expands the NTS’s enforcement framework for virtual-asset income, targeting both resident holders and non-resident beneficiaries of crypto-currency gains. The directive requires domestic exchanges to submit detailed trader-to-trader transaction logs monthly, while non-resident investors must declare overseas-held digital assets through the newly established 해외가상자산 신고 시스템 (Overseas Virtual-Asset Reporting System). Failure to report will result in automatic assessment based on estimated market values, with penalty rates reaching 25 percent for willful non-disclosure. The measure aligns with OECD’s global minimum tax discourse and introduces a mandatory 100-day grace period for voluntary regularization before intensified audits commence.

Key Takeaways

  • Mandatory Exchange-Level Reporting: All licensed virtual-asset service providers must transmit client transaction data to the NTS on a monthly basis, including wallet identifiers, trade timestamps, and fiat-on-ramp conversions.
  • Overseas Asset Declaration Obligation: Taxpayers holding virtual assets abroad must file Form 21-24 by the end of the following month, with non-compliance triggering a presumptive tax liability calculated using average quarterly exchange rates.
