South Korea May Delay Crypto Gains Tax Until 2029

South Korea may push back its planned cryptocurrency gains tax until January 2029, marking a potential fourth delay as the government weighs concerns about monitoring trading activity on foreign exchanges.

The presidential office is reportedly leaning toward postponing the levy because domestic investors could face a heavier tax burden than users trading through overseas platforms, particularly those based in the United States. Authorities are concerned that limited access to U.S. tax data could make it difficult to identify offshore crypto gains and apply the rules consistently.

The proposal would represent a change from the government's position in July, when officials said the tax would begin in January 2027. The finance ministry has since indicated that it will consult lawmakers, industry representatives and experts before deciding how to proceed.

Under the current legislation, South Korean crypto investors would pay a 20% tax on annual net gains from cryptocurrency transfers and lending, plus local income tax of 2%, bringing the total rate to 22%. The rules include an annual deduction of 2.5 million won, equivalent to approximately $1,887. South Korea's National Tax Service continues to list January 1, 2027, as the planned start date.

A major challenge is the different timelines countries have adopted for sharing cryptocurrency transaction data under the OECD's Crypto-Asset Reporting Framework (CARF). South Korea, Japan and the United Kingdom are scheduled to begin exchanging information in 2027. Singapore, Switzerland and Hong Kong are expected to follow in 2028, while the United States is not scheduled to begin until 2029.

This gap could complicate efforts to monitor Korean investors' overseas crypto holdings before the tax authorities gain broader access to international trading records. South Korea had previously argued that existing foreign financial account reporting rules could help authorities track assets held abroad.

Other major markets, including the United States, the United Kingdom and Japan, already tax cryptocurrency gains without waiting for the new cross-border reporting framework to take effect.

Meanwhile, ruling Democratic Party lawmaker Park Min-kyu has proposed moving the tax's introduction to January 1, 2029, according to local media reports. The levy was originally scheduled to take effect in 2022, but successive postponements have delayed its implementation.

A fourth delay would require parliamentary approval to amend the existing law. Until lawmakers make a formal change, the current January 2027 start date remains in place.
