Income Tax
Who this guide is for
- Foreign residents trading crypto in Korea
- Expats using Korean or overseas exchanges
- Long-term holders preparing for the 2027 rules
- People with crypto in overseas financial accounts
Quick Answer
Korea's dedicated individual income tax on gains from transferring or lending virtual assets is scheduled to apply to transactions from January 1, 2027 after a two-year delay. Foreign residents should still preserve acquisition-cost and fee records in 2026, and separately check whether overseas virtual-asset accounts fall within Korea's foreign financial account reporting rules.
Key points
- The dedicated virtual-asset income tax is scheduled to begin for transfers or lending from January 1, 2027.
- The current framework uses annual gains, necessary expenses, an annual basic deduction, and a separate tax rate.
- Pre-2027 holdings have a special deemed acquisition-cost rule in the current law.
- Overseas crypto accounts can raise a separate foreign financial account reporting issue.
- Future amendments are possible, so re-check the law before filing.
Detailed explanation
What changes in 2027
The NTS states that the dedicated taxation of virtual-asset income was delayed for two years and is scheduled to apply to transfers or lending from January 1, 2027. Under the current framework, annual consideration is reduced by recognized acquisition cost and related expenses, then by an annual basic deduction, before the separate rate is applied.
What to do during 2026
Export transaction histories from every exchange. Preserve fiat deposits, purchases, fees, wallet transfers, staking or lending records, and evidence that a transfer between wallets was not a sale. Record which wallet belongs to you and when an asset was acquired.
The current rules include a special basis rule for assets already held before the start date. That makes reliable pre-2027 records and the prescribed year-end valuation especially important.
Do not confuse two reporting systems
Tax on crypto gains and foreign financial account reporting are separate. A person may have no dedicated 2026 virtual-asset gain tax under the delayed start date but still need to examine whether overseas exchange or custody accounts are reportable.
Confirm the rules before a transaction or filing
Crypto legislation can change quickly. Confirm the start date, deduction, rate, valuation method, residency treatment, and reporting forms against the NTS immediately before relying on them.

FAQ
Does Korea tax individual crypto gains in 2026?
The dedicated virtual-asset income tax described by the NTS is scheduled for transfers and lending from January 1, 2027. Other tax or reporting issues may still apply depending on the facts.
What is the planned Korean crypto tax rate?
The current NTS framework describes a 20% national rate after necessary expenses and an annual KRW 2.5 million basic deduction. Local income tax and later law changes should be checked before filing.
Why keep 2026 records?
Cost basis, fees, wallet transfers, and the special valuation of pre-2027 holdings may affect later calculations and the ability to explain transactions.
Do overseas crypto accounts need a separate report?
They may. Korea's foreign financial account rules can include virtual assets held through overseas providers, subject to residence, exemption, and balance tests.
