How is JPYC taxed? In short, JPYC is not a "crypto asset" under Japanese law but an "electronic payment instrument", and as long as it is issued and redeemed at 1 JPYC = ¥1, no gain or loss arises against the yen. On the other hand, exchanging a crypto asset such as Bitcoin for JPYC locks in the gain or loss on the crypto-asset side at that moment, and if you buy or sell JPYC at a price other than ¥1 on an exchange, or exchange it for Korean won, USDT or the like, the difference can be subject to income calculation.
This article first checks how far the National Tax Agency's "Tax Treatment of Crypto Assets, etc.: FAQ" (last revised December 2025 (Reiwa 7)) addresses electronic payment instruments, then sets out how to think about each situation an individual might encounter when using JPYC. Because the FAQ has no Q&A that directly addresses electronic payment instruments for individual income tax, this article is a general interpretation drawn from the FAQ's treatment of crypto assets and the legal nature of electronic payment instruments; it does not calculate an individual's tax liability or handle filing on your behalf. If the amount involved is large, check with your tax office or a tax accountant.
The starting point for JPYC tax: it is an "electronic payment instrument", not a crypto asset, and exchanging it for ¥1 creates no gain or loss
The Payment Services Act defines a stablecoin that is issued in a fiat currency and redeemed for the same amount as an "electronic payment instrument", distinct from a "crypto asset" such as Bitcoin. JPYC is a No. 1 electronic payment instrument issued by JPYC Inc., a Type II funds-transfer service provider, and the issuer bears the obligation to redeem it at 1 JPYC = ¥1. The National Tax Agency's FAQ likewise defines "electronic payment instruments" as the Payment Services Act's No. 1 to No. 3 electronic payment instruments, and treats them in a separate section from crypto assets.
| Item | Content | FAQ no. |
|---|---|---|
| Acquisition cost (corporation tax) | The tax-basis acquisition cost is the value based on face value. Electronic payment instruments are considered similar in nature to demand deposits and to fall under monetary claims | 3-2-1 |
| At transfer (corporation tax) | Any difference between the consideration received on transfer to a third party and the book value is included as taxable or deductible in that fiscal year | 3-2-2 |
| At year end (corporation tax) | No year-end mark-to-market valuation is required (monetary claims are outside the scope of year-end fair-value valuation) | 3-2-3 |
| Foreign-currency-denominated (corporation tax) | An electronic payment instrument denominated in a foreign currency is converted to yen using either the year-end conversion method or the transaction-date conversion method | 3-2-4 |
| Consumption tax | A transfer of an electronic payment instrument on or after 1 June 2023 is non-taxable, as a transfer of a means of payment | 6-1 (Reference 3) |
| Individual income tax | No Q&A directly addresses electronic payment instruments; the treatment of selling, exchanging and using crypto assets (1-1 to 1-3, etc.) is provided instead | — |
※ Source: National Tax Agency, "Tax Treatment of Crypto Assets, etc.: FAQ", last revised December 2025 (Reiwa 7). The corporation-tax items describe treatment for a corporate holder, but the framing that "face value is the acquisition cost" and that the instrument is "close in nature to a monetary claim redeemable at ¥1" is useful for thinking about an individual's issuance and redemption at ¥1.
If you transfer ¥100,000 at JPYC EX and receive 100,000 JPYC, then later redeem 100,000 JPYC and receive ¥100,000, no income arises because the yen value has not changed. There is no unrealised gain either. This is the biggest difference from a crypto asset, whose appreciation is taxed when converted to yen.
Three situations where JPYC tax comes into play: exchanging for crypto, trading at other than ¥1, and exchanging for foreign currency
JPYC itself does not fluctuate in value, but when you "exchange JPYC for another asset", the gain or loss on the other asset, or the difference from ¥1, becomes relevant. For an individual, the three situations worth keeping straight are as follows.
| Situation | What to check | Basis for the interpretation |
|---|---|---|
| Exchanging a crypto asset (e.g. Bitcoin) for JPYC | Treated as "disposing of" the crypto asset at the moment of exchange. The difference between the yen value of the JPYC received (= disposal price) and the crypto asset's acquisition cost is income, generally miscellaneous income | NTA FAQ 1-1, 1-3 (sale and exchange of crypto assets) |
| Exchanging JPYC for a crypto asset | Treated as purchasing the crypto asset; the yen value of the JPYC paid becomes that crypto asset's acquisition cost. No gain or loss arises on the JPYC side | FAQ 1-5 (acquisition cost of crypto assets) |
| Buying or selling JPYC at other than ¥1 on an exchange or DEX | Selling JPYC issued at ¥1 for ¥1.20 makes the difference a gain; redeeming JPYC bought at ¥1.20 for ¥1 makes the difference a loss. The income category for an individual is thought to be miscellaneous income, though the FAQ has no direct statement | Electronic payment instruments are close in nature to a monetary claim (FAQ 3-2-1); confirm the category |
| Exchanging for Korean won, USDT etc. on Upbit and similar | Convert to yen at the exchange rate at the moment the yen-denominated JPYC is exchanged for the foreign currency or foreign-currency stablecoin, and calculate the difference. USDT is a crypto asset and its own gain or loss must be calculated separately | FAQ 1-3 (exchange between crypto assets); profit on overseas exchanges is also taxed in Japan |
| Paying at a store or service (1 JPYC = ¥1) | The same as paying in yen; no gain or loss arises on the JPYC side | Nature of an electronic payment instrument |
※ "Basis for the interpretation" is a general reading drawn from the relevant items of the NTA's FAQ and the legal nature of electronic payment instruments. For points the FAQ does not address explicitly, such as the income category for gains from trading at other than ¥1, check with your tax office or a tax accountant.
If you convert Bitcoin into JPYC or USDT on an overseas exchange, even without converting to yen, calculating income as though the Bitcoin's unrealised gain was realised at that moment is an interpretation that applies the thinking behind exchanges between crypto assets (NTA FAQ 1-3). Converting into JPYC may look like it "defers locking in the gain" because the value becomes fixed in yen terms, but for tax purposes the gain on the crypto-asset side is locked in at the moment of that exchange.
Do I need to file a return for JPYC? The ¥200,000 rule, resident tax and how losses are treated
If simply using JPYC generates no income, you do not need to file a return for it. Income arises in the situations covered in the previous section — exchanging for a crypto asset, trading at other than ¥1, or exchanging for a foreign currency — and the basic view is that this income is treated, like crypto profit, as miscellaneous income under aggregate taxation combined with salary and other income. Whether you need to file is judged by the following.
- A salaried employee receiving salary from a single employer must file an income tax return if the total of income other than salary, including JPYC-related income, exceeds ¥200,000 for the year (NTA Tax Answer No. 1900)
- Even if it is ¥200,000 or under and you do not file an income tax return, you must still declare it for resident tax
- Gains and losses from crypto assets and from JPYC-related transactions can be offset against each other within the same year's miscellaneous income. A miscellaneous-income loss cannot be offset against other income such as salary (FAQ 2-11), and because miscellaneous income has no carry-forward provision, it cannot be carried forward to the next year either
- Keep your JPYC EX issuance and redemption history, and any exchange's trading and deposit/withdrawal history, organised by year. Overseas exchanges often do not issue annual transaction reports
- If you trade at other than ¥1 or exchange for a foreign currency, keep a record of the rate at the time and use a consistent conversion method throughout the year
A rate table combining income tax (5–45%) with the 10% resident tax, and details of the ¥200,000 rule, are set out in the next column. The 20% separate self-assessment taxation under the amended Financial Instruments and Exchange Act (FIEA), enacted in July 2026, applies to crypto assets, and takes effect from 2028 at the earliest. How JPYC, as an electronic payment instrument, will be treated needs to be confirmed in the laws and notices issued as enforcement approaches.

This article is a general explanation based on National Tax Agency publications and the issuer's official materials; the NTA's FAQ has no direct statement on how electronic payment instruments are treated for individual income tax. It does not calculate individual tax amounts or handle filing on your behalf, so if the amount is large or you are unsure, check with your tax office or a tax accountant familiar with crypto assets.
Frequently asked questions
Q. Am I taxed just for holding JPYC?
A. No. JPYC is an electronic payment instrument issued and redeemed at 1 JPYC = ¥1; it does not appreciate in value, so merely holding it produces no income. The NTA's FAQ likewise treats electronic payment instruments as monetary claims similar to demand deposits (corporation-tax item 3-2-1).
Q. Does converting (redeeming) JPYC back to yen create a tax liability?
A. As long as you redeem JPYC issued at ¥1 for ¥1, no income tax arises because no gain or loss is created. If you bought the JPYC at a price other than ¥1, for example on an exchange, the difference from the redemption amount becomes a gain or loss.
Q. Is exchanging Bitcoin for JPYC taxable?
A. Yes. Exchanging a crypto asset for an electronic payment instrument is treated as disposing of the crypto asset at that moment, and the difference between the yen value of the JPYC received and Bitcoin's acquisition cost becomes income, in principle miscellaneous income (based on NTA FAQ 1-1 and 1-3). It is taxable even without converting to yen.
Q. Do I need to file a return on JPYC-related profit?
A. A salaried employee whose non-salary income — including JPYC-related income from exchanging for crypto, trading at other than ¥1, or exchanging for a foreign currency — exceeds ¥200,000 a year must file an income tax return. Resident tax must be declared even at ¥200,000 or under. Simply issuing and redeeming at ¥1 produces no income.
Q. Will JPYC be subject to the 20% separate taxation?
A. The 20% separate self-assessment taxation under the amended FIEA, enacted in July 2026, applies to crypto assets, and takes effect from January 2028 at the earliest. How JPYC, as an electronic payment instrument, will be treated needs to be confirmed in the laws and notices to be developed ahead of enforcement; as of 18 September 2026 this site has found no explicit statement in the public materials it has checked.
Q. Is consumption tax charged on JPYC transactions?
A. According to the NTA's FAQ, a transfer of an electronic payment instrument carried out in Japan on or after 1 June 2023 is non-taxable for consumption tax, as a transfer of a means of payment (FAQ 6-1, Reference 3).
