Crypto tax in Japan
How the NTA taxes crypto gains, what counts as a taxable event, losses, the proposed reform, and consumption tax.
This is general information, not legal, tax, or financial advice. Verify the current rules with a qualified local professional and the official regulator before acting.
In Japan, individuals are generally taxed on crypto profits as miscellaneous income, aggregated with other income at progressive rates, with a combined marginal rate that can reach roughly 55 percent as of February 2026. The National Tax Agency (NTA) administers this. A flat separate rate of about 20.315 percent was proposed in the FY2026 reform outline but was not yet enacted. The sale of crypto has been exempt from consumption tax since July 2017. This is not tax advice.
How crypto is taxed in Japan
This page is general information, not tax advice. Confirm your filing with a qualified Japanese tax adviser and the National Tax Agency (NTA), which administers tax in Japan. As of February 2026, profits that an individual makes from crypto are generally treated as miscellaneous income. Miscellaneous income is aggregated with your other income, such as salary, and taxed at Japan's progressive national income tax rates, which rise to 45 percent on the highest band.
On top of national income tax, individuals pay local inhabitant tax of around 10 percent and a reconstruction surtax. Taken together, the marginal rate on large crypto gains can reach roughly 55 percent. This treatment is markedly heavier than the flat rate applied to listed share gains, which is one reason reform has been debated for years.
What counts as a taxable event
A taxable event generally arises when you realise a gain, which includes selling crypto for yen, exchanging one crypto asset for another, and using crypto to pay for goods or services. Crypto received as payment for work, or from activities such as mining or staking carried on as a business, can also be taxable as income, valued when received. Simply buying and holding, or moving assets between your own wallets, is not by itself a disposal. Keep detailed records of every transaction, since you must calculate gains yourself.
Losses and the proposed reform
Because crypto gains fall under miscellaneous income, losses generally cannot be offset against salary or most other income, and they cannot be carried forward in the way capital losses on shares can. The FY2026 tax reform outline proposed taxing certain crypto gains under a flat separate rate of about 20.315 percent, aligned with listed shares, alongside the move to the Financial Instruments and Exchange Act. As of February 2026 that change had not been enacted, so the miscellaneous income treatment still applied. Confirm the current rules with the NTA.
Consumption tax
The sale of crypto assets has been exempt from Japanese consumption tax since July 2017, so buying or selling crypto does not attract consumption tax. Consumption tax can still apply to the underlying goods or services when you spend crypto, in the same way it would for a yen purchase.
