Crypto Taxation in Japan: A Complete Guide

Japan is one of the busiest crypto hubs in the world. More than 12 million local accounts now hold over ¥5 trillion in digital assets on Japanese exchanges. Because the market is big, the National Tax Agency (NTA) keeps close watch on every trade, swap, or reward. At present, gains can be taxed at rates as high as 55%, so beginners need clear rules to avoid painful fines. This guide explains today’s system, the steps to report income, common deductions, strict penalties for cheating, and a new proposal that could cut tax on crypto to a flat 20%.

Tax Authorities & Regulations

Who is the manager? Exchanges are licensed and new rules are drafted by the National Tax Agency (NTA) that collects the money and the Financial Services Agency (FSA).
Principal legislations: The Payment Services Act refers to crypto as miscellaneous income. The sliding tax scale is established under the Income Tax Act.
Up-to-date state of affairs: All profits earned by selling, trading or earning tokens are added to your annual salary and taxed as additional salary.
Change in the offing: In June 2025 the FSA suggested the transfer of crypto to the Financial Instruments and Exchange Act. Provided that it is passed by Parliament, crypto will be a financial product, spot-Bitcoin ETFs will be able to start trading, and earnings will be taxed at a flat rate of 20 percent, as with stocks.

Types of Crypto Taxes in Japan

Capital gains tax on every sale: On the sale of Bitcoin to yen, On the exchange of coins through swapping, Or on the use of shopping via crypto.
Income tax on mining rewards, staking payout, airdrop, salaries, freelance compensation, or DeFi interest.
10% local resident tax over and above the national tax you must pay.
Corporate taxes at 30% on the profits that companies actually receive in cash; token issuers no longer pay taxes on unrealised gains.
No VAT / consumption tax even when you simply send coins across wallets or you pay merchants.

Tax Rates & Brackets — simple bullets

Earn up to ¥1.95 million in a year: pay 15% total.
Earn ¥1.95 million–¥3.3 million: pay 20% total.
Earn ¥3.3 million–¥6.95 million: pay 30% total.
Earn ¥6.95 million–¥9 million: pay 33% total.
Earn ¥9 million–¥18 million: pay 43% total.
Earn ¥18 million–¥40 million: pay 50% total.
Earn more than ¥40 million: pay 55% total, the current top rate.

Note: The totals above already include the 10% local tax. Non-permanent residents pay one flat rate of 20.42% on Japan-sourced crypto income.

Crypto Transactions & Tax Treatment

Purchasing using the yen: no tax until you sell.
Sale in yen or exchange of coin: pay tax upon the difference between cost and sale price.
Mining or staking: treat the coins you receive as income by reporting their market value on the day you receive them; subsequent price changes are treated as capital gain or loss.
Being paid in crypto: this is your salary; on your payday, report the value of the yen.
Purchase of goods or services: this is a disposal and any gains or losses on the disposal is taxed.
DeFi rewards: Yield, interest and liquidity-pool distributions are income, followed by later gains at exit as capital gains.
NFT trading: the profit is income; the gas fee and listing fee are deductible.

Crypto Tax Reporting & Compliance

Japan allows no joint returns—each person files alone. Crypto users normally choose Form B and write totals in Section 6 (“miscellaneous income”). The tax year is the calendar year, and the deadline is 15 March. You must exchange CSV files, wallet logs, and transaction hashes. Japan accepts two cost-basis methods: the moving-average method (average of coins you still hold) and the total-average method (average of every purchase in the year). Late filing triggers a 5–15% surcharge plus interest; understating income can add up to 40%.

Tax Deductions & Exemptions

You can also claim direct expenses like exchange charges, mining power or dedicated equipment so long as you keep receipts. Capital losses can offset other crypto profits earned during the same year, but not salary or share-trading income and are not carried forward to the next periods. Those whose non-salary income, such as crypto, is less than 200,000 yen in the year do not usually have to file, provided, of course, that they do not claim other deductions, such as major medical expenses.

Enforcement & Penalties for Non-Compliance

Domestic exchanges must share customer data with the NTA and FSA. Bank transfers over ¥1 million coming from overseas platforms are automatically reported. The tax office also hires blockchain-analysis firms to match wallet addresses to real names.

If you file late, the NTA adds 5–15% to the unpaid tax plus daily interest. If you under-report, the surcharge can reach 40%. Hiding large gains can turn into a criminal case: the first crypto-tax conviction in 2021 led to a one-year prison term and a fine of more than ¥22 million.

Future of Crypto Taxation in Japan

Parliament plans to debate the FSA’s reclassification bill in early 2026. If it passes, crypto will move to a flat 20% separate-tax system, and losses could carry forward for three years. The same reform would open the door to spot-crypto ETFs. Policymakers hope lower taxes will stop businesses from moving overseas and attract new investment to Japan.

Conclusion

Until the law changes, Japanese residents face some of the world’s highest crypto taxes. Every sale, swap, or reward is taxable, and total rates can climb to 55%. File by 15 March, keep full records, and use reliable tax software or a licensed zeirishi to calculate average costs. Complying now avoids steep penalties and positions you to benefit if the simpler 20% flat-tax system arrives soon.
