Crypto Taxes in South Korea 2026 – NTS Complete Guide

South Korea has a large and active crypto market. After multiple delays, the country's cryptocurrency capital gains tax regime has been established. Here is what South Korean investors need to know.

South Korea's Crypto Tax Framework

South Korea's National Tax Service (NTS) classifies cryptocurrency as virtual assets (가상자산). After multiple legislative delays, South Korea's crypto capital gains tax has been established under the Virtual Asset User Protection Act and related tax legislation.

Capital Gains Tax Rate and Exemption

South Korea taxes crypto capital gains at a flat rate of 20% (22% including local income tax). Importantly, there is an annual basic deduction of 2.5 million KRW (~$1,900 USD) on virtual asset gains. Gains below this threshold are tax-free.

Net losses can offset gains in the same year, but cannot be carried forward to future years.

What Counts as a Taxable Event

• Selling virtual assets for Korean Won (KRW)
• Trading one virtual asset for another
• Using virtual assets to purchase goods or services
• Transferring virtual assets as a gift (gift tax may also apply)

Cost Basis Method

South Korea uses the moving average cost method for calculating cost basis. Each time you purchase the same virtual asset, the cost is averaged across all units held. Acquisition costs include purchase price plus transaction fees.

Exchange Reporting Obligations

South Korean crypto exchanges (KSGE-registered Virtual Asset Service Providers) are required to collect user information, verify identities, and report transaction data to the NTS. The major Korean exchanges – Upbit, Bithumb, Coinone, and Korbit – all comply with these reporting requirements.

Overseas Exchange Holdings

South Korean residents who hold crypto on foreign exchanges must declare these holdings. Failure to report foreign financial accounts holding over 500 million KRW (~$375,000) can result in significant penalties. South Korea participates in international tax information exchange agreements.

Filing Your Korean Crypto Return

Report virtual asset gains in your annual 종합소득세 신고 (General Income Tax Return) filed with the NTS. The filing period runs May 1–31 for the prior year's income. Korean tax software and certified tax professionals can help calculate gains using the moving average method and prepare the required schedules.
