Japan's government and ruling party are advancing a proposal to impose a flat 20% tax on cryptocurrency trading gains, aligning it with the tax treatment of stocks and investment trusts. The proposed tax structure includes a 15% national tax and a 5% local tax. This initiative aims to reduce the tax burden and stimulate the domestic cryptocurrency market. The measure is expected to be included in the 2026 tax reform outline, with finalization anticipated by the end of the year.
