Japan Crypto Tax Reform: The Country Moves to Apply Flat 20% Rate

Japan’s New 20% Crypto Tax Plan Aims to Boost Trading and Regulation

Japan is preparing one of its most significant Japan Crypto tax reforms, aiming to introduce a flat 20% levy on cryptocurrency trading gains. The move signals a major shift in the Japan Cryptocurrency market approach and could finally offer long-awaited crypto tax relief to retail investors.

Currently, crypto tax in Japan can climb to as high as 55% due to its calculations on “miscellaneous income”, meaning profits are added to a person’s salary and taxed under a progressive system that can reach up to 55%. 

Now under the new proposal, cryptocurrency gains will be taxed at a fixed 20%, the same rate currently applied to stocks and investment funds. 

Japan Crypto Tax Update: 20% Flat Levy Coming in 2026

The reform, expected to be included in the nation's 2026 tax policy outline, would place digital assets under a separate levy category rather than grouping them with salaries or business earnings. Under the new structure, collection of 20% will be distributed as follows:

• 15% of cryptocurrency's income would go to the national government

• 5% would flow to local prefectural and municipal authorities

Lowering the burden will boost trading activity and strengthen the country’s digital-asset ecosystem, which is one of the most active players. Industry data highlights that the country has around 8 million active crypto-accounts, and a September spot trading volume reached 1.50 trillion yen ($9.6 billion). If passed, the reform would position the nation among the more competitive countries with virtual product taxes and regulation regimes. 

Acceptance Phase: Expansion in Virtual Asset Area

Beyond taxation, the government is also advancing broader Japan cryptocurrency regulation, as the developed nation didn’t want to fall behind in the global race. The Financial Service Agency (FSA) is drafting rules to treat digital assets as financial products subject to insider-trading laws. This would apply to all 105 cryptocurrencies listed on domestic exchanges. 

Along with that, the country is pushing a rule that will require exchanges to maintain reserve funds to protect customers during hacks or system failures. Until now, exchanges only had to keep customer assets in cold storage, but not extra reserve. 

The moves got accelerated, as the whole continent is participating in the digital space very actively. India, home of 100M crypto users, is reviewing its VDA policies after years of heavy taxation and strict AML rules with the evaluations on how stablecoins regulate, clarify definitions. South Korea, another crypto-admirer, also plans to require sender/reciever details even for crypto-asset transfers under 1 million won ($680), which aims to close loopholes that previously allowed users to bypass reporting requirements.

Future: Asset Managers Prepare for the Shift

Major institutions such as Nomura Asset Management, Daiwa, Mitsubishi UFJ, and Amova are building crypto-focused teams. They are evaluating new fund lineups for both retail and institutional investors, anticipating rising demand once the new Japan tax on crypto regime is implemented. 

Challenges remain, including pricing benchmarks, custody systems, and liquidity management, but momentum is clearly growing.
