Japan sets crypto tax shift to 20.315% and targets FIEA enforcement on Jan. 1, 2028

Japan is reworking crypto taxation and oversight, including a move away from a miscellaneous income rate of up to 55% toward a 20.315% separate tax framework, with full enforcement tied to a Financial Instruments and Exchange Act (FIEA) update on Jan. 1, 2028. The package also adds a three-year loss carryforward and changes corporate treatment from the fiscal year starting April 1, 2026. Critics argue the 2028 schedule could slow the rollout of products such as bitcoin ETFs.
