South Korea Tax Agency to Hire Professional Crypto Custodians

The South Korean National Tax Service (NTS) has announced plans to transition the management of confiscated digital currencies to professional private custody providers. This strategic shift, scheduled to be implemented within the first half of 2026, marks a significant change in how the state handles assets seized from tax delinquents. By moving away from self-custody practices, the NTS aims to enhance the security and transparency of its digital asset holdings, which include major cryptocurrencies like Bitcoin (BTC) and Ethereum (ETH).

Enhancing Security Protocols for Seized Assets

The decision to outsource custody follows security vulnerabilities identified during recent enforcement actions. On February 26, the accidental exposure of mnemonic phrases during a public report on tax delinquent searches resulted in two separate theft incidents involving seized virtual assets. To prevent future breaches, the NTS is establishing rigorous selection criteria for potential partners. Candidates will be evaluated based on their security infrastructure, corporate scale, and compliance with insurance requirements mandated by the Virtual Asset User Protection Act.

This legislative framework requires service providers to maintain high standards of investor protection and asset segregation.

Structural Reforms and Specialized Task Forces

To oversee this transition, the NTS established the Virtual Asset Management System Upgrade Task Force on March 11. This body is tasked with refining the entire operational lifecycle of seized assets. The scope of their work includes:

• Modernizing the manual for the seizure, custody, and liquidation of digital assets.
• Expanding specialized technical training for tax officials.
• Establishing a dedicated Digital Assets Management Division to centralize taxation and sales responsibilities.

This is a method commonly adopted by developed countries and will be implemented to ensure the integrity of our digital financial administration.

As the South Korean government tightens its regulatory grip on the blockchain sector, these administrative upgrades reflect a growing institutional maturity. The integration of professional custody services aligns the National Tax Service with global best practices, ensuring that virtual assets are treated with the same level of security and legal oversight as traditional financial instruments. These measures are expected to bolster public trust in the state's ability to manage complex digital property effectively.
