Japan's plan to tax crypto at a flat 20%: who it would help, and the catch

Bottom line: from up-to-55% to a flat 20% — with conditions
In Japan, crypto profits have been taxed as miscellaneous income at rates up to ~55%. The 2026 tax-reform blueprint (late Dec 2025) proposes a flat 20% separate tax — the same treatment as stocks — plus a multi-year loss carryforward. The catch, as reported: relief would first apply only to "specified crypto assets" handled by registered businesses.
Key points
- Direction: progressive (up to ~55%) → flat 20% separate tax.
- A loss carryforward (reported: 3 years) is under consideration.
- Initially limited to "specified crypto assets"; BTC and ETH are expected to qualify, but criteria are not final.

Why this matters for "crypto in Japan"
High, progressive taxation has long been cited as a reason Japanese users and builders looked abroad. A flat 20% rate would bring crypto in line with equities — but only once the FIEA reclassification and the "specified asset" framework are in place.
Still a blueprint
A tax-reform blueprint signals direction, not enacted law. Timing, scope and conditions will be set by later legislation. Confirm with the National Tax Agency.
