📝 Description
Japan was one of the first countries in the world to regulate cryptocurrencies. The National Tax Agency (NTA) classifies gains from cryptocurrencies under the category of "Miscellaneous Income" (Zatsu-shotoku).
Japan is known for having one of the heaviest tax regimes in the world for digital assets, although debates regarding a potential reform toward a flat tax are regularly brought to the government. This guide explains the Japanese legislation in effect for 2026 and how to use Waltio to generate a compliant report.
Essential Crypto Tax Facts in Japan
Category | Tax Rule |
Global Tax Rate | Progressive scale (Up to 55% maximum) |
Exemption Threshold | 200,000 JPY (~€1,200) for salaried employees under conditions |
Crypto-to-Crypto Trades | Taxable (Triggers capital gains calculation) |
Loss Offsetting | Very limited (No carry-forward to the following year allowed) |
Filing Deadline | March 15 of the following year (Kakutei Shinkoku) |
💰 Calculation and Tax Rates: The Progressive Scale
In Japan, there is no reduced flat rate for crypto capital gains. Your net profits are added to your salary and other income, then taxed according to a progressive scale.
The tax consists of two parts:
National Income Tax: Ranges from 5% to 45% depending on your total income bracket.
Inhabitant Tax (Local): It is fixed at 10%.
The maximum effective tax rate can therefore reach 55% for very high earners (generally those exceeding 40 million Yen per year).
🛡️ The 200,000 JPY Rule
If you are a salaried employee (with a single employer) and your net crypto gains for the year do not exceed 200,000 Yen (JPY), you are exempt from filing a national income tax return. (Note: you must still declare this amount for the local inhabitant tax).
📉 Strict Treatment of Losses
The Japanese National Tax Agency is very strict on this point:
You cannot use your crypto losses to reduce taxes on other types of income (such as your salary or real estate gains).
You cannot carry forward net losses from one year to the next. If you end the year 2026 with an overall crypto loss, this loss is fiscally "lost."
🔄 Crypto-to-Crypto Operations (Trading)
Exchanging one cryptocurrency for another (for example, using Bitcoin to buy Ethereum) is considered by the Japanese tax authorities as a realization of profit. This is equivalent to selling your Bitcoin for Yen (triggering tax on the latent capital gain) and then using those Yen to buy Ethereum.
⚙️ How are these managed on Waltio?
Great news: Waltio's behavior is perfectly aligned with Japanese NTA requirements.
The software automatically considers every Crypto-to-Crypto exchange operation as taxable and calculates the realized gain or loss at the exact second of the transaction.
Your process: You have no manual action to perform for these operations. The calculation engine will process your trades exactly as required by Japanese law.
🎁 Passive Income (Staking, Mining, Lending)
According to Japanese guidelines, cryptocurrencies acquired via mining, staking, lending, or airdrops are considered taxable income at the time of receipt. The value to be declared is the Fair Market Value of the token in Yen at the exact moment you take control of it.
⚙️ How are these managed on Waltio?
To ensure smooth global tracking, Waltio applies a specific default methodology:
This income is marked as non-taxable upon receipt.
The software assigns them an acquisition value of €0 (or 0 JPY).
Practical consequence: Taxation is deferred. The operation only becomes taxable when you sell these tokens. Since the acquisition price is 0, the entire proceeds of the sale will be considered a capital gain and added to your income for the year of sale.
To ensure taxation is accounted for upon receipt (Strict NTA Compliance):
To strictly comply with the immediate reporting obligation required by the Japanese tax authorities, manual action is required on Waltio. You will need to individually modify each passive gain transaction to enter its acquisition price (the market price of the token on the exact day of receipt). This way, the acquisition value will no longer be 0, the operation will be counted as income to be declared for the current year, and this will constitute your new purchase price for the future.
✅ What Triggers Tax
Any exit from the crypto ecosystem triggers a profit (or loss) calculation:
Sale for fiat currency: Converting your cryptos into Japanese Yen (JPY), Dollars (USD), etc.
Payment for a good or service: Using your cryptocurrencies in a store (physical or online) is fiscally considered a sale of your assets.
📝 Filing:
Tax Period: The calendar year (January 1 to December 31).
The Declaration (Kakutei Shinkoku): The income tax filing period runs every year from February 16 to March 15 of the following year. The calculated tax must be paid by March 15 at the latest.
Disclaimer: This guide is provided for purely informational and educational purposes. Legislation surrounding digital assets in Japan is among the strictest in the world and is subject to frequent legislative discussions. Waltio does not provide tax or legal advice. We strongly recommend consulting a certified tax accountant (Zeirishi) in Japan to validate your declaration and your choice of accounting method.
