The South Korean government has confirmed that it will tax profits from virtual asset transactions starting January 1, 2027, according to the current timetable. This policy has been postponed three times previously, and the latest statement indicates that the start date will not be adjusted for the time being. However, if practical problems arise after implementation, the government may still revise some of the details.

A timetable was finalized after three postponements.

South Korean Deputy Prime Minister and Minister of Strategy and Finance Koo Yoon-cheol stated at a plenary session of the National Assembly's Strategy and Finance Committee on July 29 that the government is currently proceeding with preparations with the taxation scheduled for next year and will review the system design if necessary.

According to South Korea's Income Tax Law, income from transactions involving cryptocurrencies and other virtual assets will be subject to taxation. South Korea originally planned to implement this in January 2022, but due to a lack of sufficient reporting and supporting infrastructure among exchanges, tax authorities, and investors at the time, the policy was postponed three times, with the final effective date set for January 1, 2027.

Tax rates and deductions will not be adjusted for the time being.

Under the current framework, investors are entitled to a basic deduction of 2.5 million won per year. Any amount exceeding this is subject to a national tax rate of 20%, and after local taxes are included, the total tax burden can reach up to 22%.

The South Korean government currently plans to classify virtual asset gains as "other income" rather than general capital gains. This means that crypto asset gains will be subject to a separate calculation and reporting process and will not be taxed together with wages or business income.

When calculating taxable income, investors need to deduct identifiable acquisition costs from the sales proceeds. If multiple local or overseas trading platforms are used simultaneously, investors may need to verify transaction prices, transaction fees, and cross-platform transfer records themselves when filing their tax returns.

• Annual basic deduction: 2.5 million Korean won
• National tax rate: 20%
• Total tax burden after local taxes: up to 22%

The report mentions that local exchanges are expected to play a significant role in providing trading data and supporting annual tax filing. For investors holding overseas accounts or frequently trading across platforms, the reporting burden may be higher, as local records may not cover the complete trading history.

Loss carryforward becomes the focus of controversy

At the meeting, Kim Sang-hoon, a lawmaker from South Korea's ruling People Power Party, questioned that the current plan does not allow virtual asset investors to carry forward their losses, which may weaken local trading demand and cause some funds to flow overseas.

The concept of loss carryforward refers to the ability of taxpayers to offset investment losses from previous years against profits in future years. This arrangement is not yet included in South Korea's current proposed crypto tax system.

Koo Yoon-cheol responded that the government could reassess the issue after the tax is implemented. He stated that if difficulties arise in terms of fairness, compliance, or market aspects in the early stages of implementation, the government will consider further adjustments.

Should it be taxed as capital gains?

Some lawmakers and investors argue that South Korea should follow the example of certain overseas markets and treat gains from crypto assets as capital gains. If the classification changes, deduction standards, loss handling methods, and reporting rules may all be adjusted accordingly.

However, the South Korean government believes that this issue cannot be addressed solely in relation to digital assets. Koo Yoon-cheol stated that if the classification is to be changed, the broader capital market tax system, including stocks, funds, and derivatives, must be reviewed in conjunction with it.

This means that even if South Korea adjusts its cryptocurrency tax system in the future, it will likely require broader legislative and regulatory coordination. Based on current progress, the core policy arrangement remains to implement it on the set date first, and then decide whether to revise it based on the implementation results.
