Nhật Bản năm 2026 cải cách chính sách thuế tiền mã hóa, thuế Bitcoin giảm từ 55% xuống còn 20%, tính toán như thế nào?

【Coin Circle】Japan’s Financial Services Agency plans to launch a major regulatory reform in April 2026, reclassifying cryptocurrencies such as Bitcoin and Ethereum as financial products. While this change appears to be an administrative adjustment, it actually leverages a massive tax mechanism.

Renowned analyst Willy Woo highlighted the economic logic behind it: What does financial product classification mean? It means the tax rate on cryptocurrency asset returns will drop significantly from the current marginal income tax rate to a fixed 20%. In other words, if your annual income exceeds $57,000, you might have previously paid 43-55% in taxes, but now you’ll only pay 20%. What does this mean for Japanese investors? Direct increase in purchasing power.

The most affected are institutions like Metaplanet. It previously gained tax arbitrage advantages through self-custody of Bitcoin, an advantage that is about to be eroded. Meanwhile, approximately 110 other cryptocurrencies are also included in the reform scope, though staking rewards will still be taxed at marginal rates—indicating that the policy is still being refined, with not all returns treated equally.

Overall, this reform aims to reduce the burden on Japanese investors and is expected to stimulate more personal and institutional appetite for Bitcoin purchases. How the market responds remains to be seen in 2026.
