Japan's 2026 Tax Reform Proposal: Lowering Cryptocurrency Taxes and Expanding NISA Account Eligibili

the Financial Services Agency of Japan has proposed a series of tax reform plans for 2026, aimed at comprehensively adjusting the current cryptocurrency tax framework. The core content of the reform includes two aspects: first, changing the current comprehensive tax system (when cryptocurrency income is combined with salary income for taxation, the highest tax rate can reach 55%) to a separate fixed tax rate system, with a tax rate of about 20%; second, introducing a "three-year loss carryforward" mechanism similar to stock market rules (i.e. losses can be offset against taxable income in the next three years).
