South Korea to Tax Crypto Gains at 22% Starting 2027

The South Korean government will impose a flat 22% tax on gains from virtual assets beginning Jan. 1, 2027. The levy applies to residents whose annual income exceeds ₩2.5 million and covers gains from the sale or borrowing of virtual currencies, classified under the current Income Tax Act as “other income.” The rate consists of 20% national income tax and a 2% local income tax. Individuals with annual income below ₩2.5 million remain exempt under the retail trader exemption. The tax will apply to domestic trades and to cross-border transactions that involve at least one Korean resident.

The National Tax Service and the Ministry of Economy and Finance have begun final administrative steps toward implementation. The original start date of 2025 was postponed twice; the government has set the firm start date of Jan. 1, 2027. A draft notice with guidelines for implementation is expected in 2026, providing roughly 18 months for exchanges and investors to adapt systems and procedures.

Regulators are negotiating data-sharing and withholding arrangements with the country’s five largest digital-asset platforms: Upbit, Bithumb, Coinone, Korbit and Gopax. Rules under discussion include how exchanges will track disposals, lending and borrowing transactions, how they will withhold taxes where required, and how they will report customer activity to tax authorities. Tax officials are also defining reporting and collection procedures to cover both domestic and applicable cross-border activity.

South Korea has an estimated 13.26 million crypto traders. Following the announcement, some traders have explored moving funds to foreign exchanges in jurisdictions without similar capital gains rules. Earlier delays in implementation were linked to some trading volume moving offshore.

Director Moon Kyung-ho of the income tax department at the Ministry of Economy and Finance confirmed the timetable, saying, “We will proceed with virtual asset taxation as scheduled in January next year.”

Other governments are also revising crypto tax rules. Germany plans to end its one-year tax-free holding exemption from 2027 and expects the change to raise about €2 billion in additional revenue. Under current German law, crypto assets held longer than one year are exempt from tax, while shorter holdings are taxed at progressive income rates plus a solidarity surcharge. The proposed change would align Germany’s approach more closely with capital gains regimes that apply fixed or higher rates to crypto profits.

South Korean officials say further details on compliance requirements for individual taxpayers and the duties of exchanges will be published next year. Exchanges and traders have until the start of 2027 to implement systems for tracking transactions, reporting customer activity and handling any required withholding.
