Korea to Begin Taxing Crypto in 2027: Who Pays and How Much?
Korea to Begin Taxing Crypto in 2027: Who Pays and How Much?
Korea’s taxation of virtual assets is scheduled to begin on January 1, 2027, after being postponed three times.
From that date, income earned from transferring or lending virtual assets will generally be subject to Korean income tax.
How Will Crypto Tax Be Calculated?
Tax will not be imposed on the entire amount received from selling crypto.
Instead, taxable income will generally be calculated based on the actual profit, after deducting the acquisition cost and certain related expenses.
An annual basic deduction of KRW 2.5 million will apply.
Under the current system, the taxable amount is subject to a 22% tax rate including local income tax.
What About Crypto Purchased Before 2027?
For virtual assets acquired before the new tax system begins, an important rule applies when determining the acquisition cost.
The acquisition cost will generally be based on the higher of:
The actual purchase price, or
The relevant market value as of December 31, 2026
This rule can significantly affect the amount of taxable gain for investors who have held crypto for several years.
For example, if a cryptocurrency was originally purchased at a low price but its value had increased substantially by the end of 2026, the year-end market value may be used as the acquisition cost when calculating taxable income.
Not Every Crypto Transaction Is Simple
Buying and selling crypto is only one part of the market.
Transactions such as:
Staking
Lending
Airdrops
Hard forks
Decentralized exchange transactions
can raise more complicated tax questions.
There is still debate over when income from some of these transactions should be recognized and how the acquisition cost should be determined.
Depending on the structure of a transaction, even similar crypto rewards may potentially be treated differently for tax purposes.
What About Overseas Exchanges and Personal Wallets?
Another major issue is whether Korean tax authorities can accurately identify transactions conducted through overseas exchanges, decentralized exchanges, and personal wallets.
Korean authorities expect to use information from domestic exchanges, overseas financial account reporting, and international information-sharing systems such as CARF to improve the tracking of virtual asset transactions.
International crypto-asset information exchange is also expected to begin from 2027.
Can Crypto Losses Be Carried Forward?
Under the current system, losses from one year generally cannot be carried forward and deducted from crypto gains in later years.
Because virtual asset prices can fluctuate significantly, this remains one of the issues being debated ahead of implementation.
What Should Crypto Investors Prepare for?
With the new tax system approaching, investors should pay particular attention to:
Their actual acquisition cost
The value of crypto held at the end of 2026
Records of transactions and fees
Overseas exchange and wallet transactions
The tax treatment of staking, airdrops, and other complex transactions
The final tax treatment can differ depending on the type of transaction and the investor’s individual circumstances.
If you hold or trade virtual assets in Korea, reviewing your transaction history before 2027 and consulting a qualified tax professional can help you understand how the new rules may apply to you.
