Tevau Card and Taxes in Japan: What You Need to Know

Many crypto users assume taxes only apply when you cash out to your bank account. In several countries, though, spending crypto directly — not just selling it — can trigger a tax event. Japan is one of them, and its rules around crypto income are stricter than many spenders realize. If you use a card like Tevau’s to spend USDT at checkout, that transaction may be treated as a taxable disposal, not a simple purchase. Japan’s 2026 tax reform outline also proposes real changes to how crypto is taxed going forward. This tevau card tax Japan guide walks through the current rules, what might change, and how to keep useful records.

Tevau Card Tax Japan: How Current Rules Work

Under Japan’s current system, cryptocurrency gains count as “miscellaneous income” (雑所得). This differs from the capital gains treatment used in some other countries.

Miscellaneous income gets added to your total income, including your salary. It’s taxed at progressive national rates from 5% to 45%.

On top of that, a flat 10% local inhabitant tax applies. Combined, the maximum rate reaches around 55%. Some sources cite 55.945%, including a reconstruction surtax.

If your crypto-related profit exceeds ¥200,000 in a year, you generally must declare it on your income tax return. There are some exceptions for people not otherwise required to file.

Does Spending With a Crypto Card Count as a Taxable Event?

In Japan, selling, spending, or exchanging crypto is generally a taxable event. It isn’t limited to cashing out to yen.

This matters for cards like the Tevau USDT Visa card. When you spend USDT at checkout, the card converts it to fiat currency at that moment.

That conversion can trigger a taxable disposal of the underlying crypto — similar to selling it. Each purchase, in principle, is its own taxable event.

Under the current system, losses can only offset other miscellaneous income gains within the same year. They can’t reduce your salary or other income categories, and they can’t be carried forward.

Japan’s 2026 Crypto Tax Reform — What’s Changing

Japan’s government released a Fiscal Year 2026 Tax Reform Outline on December 19, 2025. It proposes a flat 20% separate self-assessment tax rate for “specified crypto assets.”

Combined with other charges, this comes to roughly 20.315%. It would apply to assets traded on Financial Services Agency (FSA)-registered exchanges.

The proposal would also introduce a 3-year loss carry-forward for qualifying assets — a meaningful change from the current no-carry-forward rule.

As of mid-2026, this reform is not yet fully in effect for individuals. Implementation is anticipated for 2027 or later, pending further legislation. Treat it as a pending change, not a settled fact.

Assets that don’t qualify as “specified crypto assets” are expected to stay under the older miscellaneous income rules, even after reform. This includes tokens on unregistered or overseas exchanges, NFTs, and staking or lending rewards. For background on the registration process itself, see the official Financial Services Agency website.

Many tevau card tax Japan questions right now center on this proposed reform. Until it’s finalized, treat any estimate as provisional. Tax rules are just one part of the bigger regulatory picture. See our piece on whether governments might restrict USDT cards for more context.

Tevau Card Tax Japan: Keeping Good Spending Records

Good records make tax season easier, whatever the final rules turn out to be. Getting your paperwork right starts with good habits early, not scrambling later. Consider tracking these for every card top-up and purchase:

• Transaction history — dates, amounts, and merchant details for each card use
• Top-up dates — when you converted USDT, and how much
• Values at time of spend — the yen value of your USDT at the moment of each transaction

You can find your transaction history inside the Tevau app, alongside your top-up records. Recording the yen value at the time of each spend, using a snapshot from a source like CoinMarketCap, can help later.

This isn’t a substitute for professional advice — it’s simply good practice for anyone spending crypto regularly. If you’re comparing options across the region, our roundup of the best crypto cards for Asia users covers more than just Japan.

Frequently Asked Questions

Is using a crypto card the same as selling crypto for tax purposes?

This is one of the most common questions we hear. In Japan, it can be treated similarly to a sale. Spending crypto through a card generally counts as a taxable event, not just a purchase. Confirm your specific situation with a tax professional.

Do I need to report small crypto card purchases?

If your total crypto-related profit for the year exceeds ¥200,000, you generally need to declare it. This applies whether the profit comes from one large transaction or many small ones. Some people not otherwise required to file may have exceptions. A licensed tax professional can confirm your specific filing obligations.

Will the 2026 reform lower my tax on card spending?

Possibly, for qualifying assets — but it isn’t in effect yet. The proposed 20% flat rate would apply to “specified crypto assets” on FSA-registered exchanges. Implementation is anticipated for 2027 or later, pending further legislation. Until then, current progressive rates apply.

Can losses from crypto card spending reduce my other income?

Under the current system, no. Losses can only offset other miscellaneous income gains in the same year. They can’t reduce salary income, and they can’t be carried forward to future years.

Conclusion

Spending crypto in Japan, including through a Tevau card, can carry tax implications you might not expect. Current rules tax crypto gains as miscellaneous income, while the proposed 2026 reform could simplify things for certain assets eventually. Keeping clear records of your top-ups, transactions, and values at time of spend puts you in a stronger position either way.
