South Korea has not estimated the tax revenue or administrative costs tied to its planned January 2027 taxation of virtual asset income, a policy expected to affect about 13 million investors. The Ministry of Economy and Finance and the National Tax Service said they could not quantify the fiscal impact before the first filing scheduled for May 2028. The National Assembly Budget Office also said it could not reasonably estimate the revenue effect of abolishing the tax because data on acquisition costs, transfer amounts and taxable investors was insufficient. The National Tax Service said 3.626 billion won ($2.7 million) had already been spent or earmarked for preparations. A parliamentary study proposed raising the current 2.5 million won taxable threshold to as much as 20 million won, while nominee Lee Hyoung-il said the tax would begin as scheduled.
