South Korea Weighs a Fourth Delay to Its Crypto Gains Tax
A reported push to move the levy to 2029 turns on when US trading data reaches tax authorities. Nothing is law yet.
South Korea is reportedly weighing a fourth delay of its crypto gains tax, moving the start from January 1, 2027 to January 1, 2029. The reported rationale is that US data would not be exchanged under the OECD framework until 2029. Nothing is law yet; the National Assembly would have to amend the statute.
The Ledger Desk · 3 min read- The legal start date reported by CoinDesk is January 1, 2027; a move to January 1, 2029 would be the fourth postponement and is not yet law.
- The reported rationale is enforcement asymmetry: officials fear the tax would fall mainly on users of South Korean exchanges while US data is unavailable until 2029.
- A change requires an amendment by the National Assembly, and CoinDesk reports a decision is expected by early December.
- The reported terms are 20%, or 22% with local income tax, on annual net gains above a 2.5 million won deduction.
- For compliance teams, the prudent assumption until an amendment passes is the January 1, 2027 date.
South Korea may postpone its tax on crypto gains for a fourth time, from January 1, 2027 to January 1, 2029. According to CoinDesk's October 26, 2026 report, a lawmaker has proposed the 2029 date and the presidential office is reportedly leaning toward a delay, citing unnamed officials relayed by Newsis. None of this is law yet: the National Assembly must pass an amendment, and CoinDesk reports a decision is expected by early December.
The enforcement-gap argument
The core rationale is about visibility, not rate. CoinDesk reports that officials fear the tax would fall mainly on users of South Korean exchanges if US trading data, which would flow under the OECD's Crypto-Asset Reporting Framework, does not become available until 2029. One official is quoted as saying almost half of the crypto market is the US. This is the reported view of unnamed officials, so it should be read as a stated concern rather than a measured figure.
What the tax would do
CoinDesk reports that annual net income from crypto transfers or lending would be taxed at 20%, or 22% including local income tax, after a 2.5 million won deduction. These are the terms as reported on October 26, 2026, and they would change only if lawmakers amend them. A delay would not alter the rate on its face; it would move the date from which gains are counted, and a fourth postponement is the only change currently reported.
The incentive question
This is our reading, not a sourced finding: a tax enforceable only on domestic venues creates an incentive to shift activity toward venues beyond its reach, which is the mechanism officials appear to be describing. Whether a 2029 start would line up with the arrival of US data depends on reporting timelines that this piece has not verified against OECD documents, so compliance teams should treat that alignment as an open question rather than a settled fact.
What compliance teams should watch
Until an amendment passes, the start date reported by CoinDesk remains January 1, 2027, so exchanges and advisers have reason to plan for it. Watch the National Assembly's calendar through early December, any change to the deduction or rate, and whether a delay is paired with earlier domestic reporting duties. Asia News Network and FinanceFeeds have also covered the earlier postponements and the asset-discrimination debate surrounding the tax.
- Is South Korea's crypto gains tax officially delayed to 2029?
- No. CoinDesk reports that a lawmaker has proposed 2029 and that the presidential office is leaning toward a delay, citing unnamed officials relayed by Newsis. The National Assembly has not passed an amendment, so the reported start date remains January 1, 2027.
- Why does the US data-sharing date matter to the delay?
- CoinDesk reports officials worry that without US data until 2029, the tax would fall mainly on users of South Korean exchanges, because the US accounts for a large share of the crypto market. This is a reported concern, not a measured figure.
- What are the reported tax terms?
- CoinDesk reports that annual net income from crypto transfers or lending is taxed at 20%, or 22% including local income tax, after a 2.5 million won deduction.
