Japan just cut its crypto tax from 55% to 20%

Japan's parliament has officially approved legislation moving crypto regulation under the Financial Instruments and Exchange Act (FIEA), with the bill clearing the Upper House on July 15 after passing the House of Representatives last month. The reforms transfer oversight of crypto trading from the Payment Services Act to the FIEA, with the Financial Services Agency treating crypto assets as financial products distinct from traditional securities.

Crypto gains are currently taxed as miscellaneous income at progressive rates reaching roughly 55%. The policy path would shift this to flat separate taxation of about 20%, matching listed stocks and bonds. The reduced rate applies to transfers of crypto assets registered in the Registry of Financial Instruments Business Operators, with the gain subject to separate taxation at a rate of 20.315%, inclusive of national income tax, a surtax, and local inhabitant tax.

Two Timelines, Not One

Most coverage has blurred a critical distinction. The FIEA reclassification is targeted to take effect in fiscal 2027, roughly a year after enactment. The flat tax follows separately under the 2026 Tax Reform Outline and would activate in 2028. In practice, that means Japan could see institutional product availability first and retail tax relief the year after.

Under certain conditions, losses from transfers of specified crypto assets can be carried forward for three years to offset capital gains from other specified crypto asset transfers. Notably, stablecoins are carved out entirely, remaining under the Payment Services Act as electronic payment instruments, a deliberate split that lets Japan's banking giants MUFG, SMBC and Mizuho pursue their joint stablecoin plans on a separate track.

Eight Years in the Making, and New Teeth

Crypto in Japan has been governed since 2017 by the Payment Services Act, a framework built in the aftermath of the Mt. Gox collapse that treats digital assets primarily as payment tools, with a correspondingly light disclosure and protection regime. The FSA will gain authority to enforce market manipulation rules, mandate transparent order books, and require licensed exchanges to segregate customer assets, addressing longstanding concerns highlighted by the 2018 Coincheck hack.

Penalties for operating an unregistered crypto business will also increase significantly: the maximum prison sentence rises from three years to ten. The bill extends insider-trading enforcement to crypto for the first time.

The reclassification also opens a path for spot $BTC exchange-traded funds. Because the FIEA governs the products that funds can hold, moving crypto under its umbrella removes a structural barrier that kept Japanese asset managers from launching regulated bitcoin ETFs. Roughly 70% of Japan's 13 million-plus crypto accounts hold less than approximately $43,600, a heavily retail-skewed market that stands to benefit directly from the tax cut.
