日本擬將加密貨幣稅率從 55% 降至 20%，推動 Web3 成為國家戰略！
📌 Key Highlights
• Japan plans to introduce a flat 20% crypto capital gains tax starting in 2026, replacing the current progressive rate that goes up to 55%.
• Crypto assets will be regulated under the same framework as equities, enhancing protections against insider trading and unfair practices.
• Investors will benefit from three-year loss carry-forward rules, improving flexibility and risk management.
• This tax reform is part of Japan’s broader Web3 national strategy, shifting towards a balanced approach between innovation and risk control.
Why Change the Tax System? How Harsh Is It Today?
Currently, Japan taxes cryptocurrency gains under the comprehensive income tax regime, similar to salary income — with a top rate of 55%. In contrast, stocks and investment funds are only taxed at 20%, prompting many investors and companies to avoid domestic crypto trading in favor of overseas platforms.
This disparity not only suppresses innovation but has also caused Japan to fall behind in the global digital asset race.
A Closer Look at Japan’s New Crypto Tax Reform: 3 Key Changes
1. Flat 20% Tax Rate — Significantly Lower Burden
The LDP (Liberal Democratic Party) has proposed a flat 20% capital gains tax for crypto starting in fiscal 2026, which would drastically reduce investment costs and reporting complexity.
2. Classified Under the Financial Instruments and Exchange Act (FIEA)
Crypto will be integrated into the FIEA, just like equities. This will allow the government to regulate pre-listing information, effectively preventing insider trading and ensuring fair market conditions.
3. Loss Carry-Forward for 3 Years — Like Stocks
Crypto investors who incur losses will be allowed to carry forward those losses for up to three years to offset future gains — just like with equities — significantly improving risk-adjusted portfolio management.
From Tight Controls to Embracing Web3: Japan’s Strategic Shift
Following major exchange hacks like Mt. Gox in 2014 and Coincheck in 2018, Japan became one of the strictest regulators of cryptocurrencies in the world. The FSA enforced mandatory KYC, AML, cybersecurity, and compliance protocols, prioritizing investor protection but limiting innovation.
That began to change when Prime Minister Fumio Kishida unveiled his “New Capitalism × Web3” strategy. As part of this initiative, Japan began to support blockchain and DeFi adoption, aiming to retain domestic tech talent and stay globally competitive.
Potential Market Impact of Japan’s Crypto Tax Reform
If enacted, the proposed tax changes could accelerate crypto adoption by both individuals and corporations. The lower tax burden and clearer rules may increase liquidity, attract institutional capital, and foster the development of a robust digital asset infrastructure.
This reform aligns with Japan’s larger goal of becoming a global hub for digital finance, competing with crypto-friendly jurisdictions like Singapore and the UAE.
A regulated yet investor-friendly environment could bring in international capital, energize domestic markets, and position Japan at the heart of the Web3 economy.
Optimism is already growing. Metaplanet, Japan’s largest corporate Bitcoin holder, was recently added to the FTSE Japan Index, a sign of increasing mainstream recognition. On August 25, 2025, the company bought another 103 BTC, bringing its total holdings to 18,991 BTC.
Future Challenges and Outlook
Despite clear reform directions, three major challenges remain:
Market volatility – How can retail investors be protected during large price swings?
Enforcement of insider trading regulations – Can the FSA effectively ensure compliance across exchanges and actors?
Parliamentary approval process – Political debate and competing priorities may delay full implementation of the reforms.
Still, these proposed changes clearly reflect Japan’s ambition to reclaim its position at the forefront of global crypto finance. Backed by a stable legal system and innovation-friendly policies, Japan is poised to become Asia’s leading regulated crypto hub.
