According to a JBA survey on crypto assets, 84% of people would increase their investment if a separate tax rate of 20% were introduced! | JBAの暗号資産アンケートで分離課税20%導入の場合84%が投資増額意向か！？
一般社団法人日本ブロックチェーン協会（JBA）は7月18日、「暗号資産に関する税制改正要望書」を政府へ提出し、同時に税制を検討するためのアンケート調査の結果も公表したそうでアンケートが行われたのは、2025年4⽉24⽇（⽊）〜4⽉25⽇（⾦）。⽇本に居住する20代〜60代の男⼥1,500名を対象としたそうで次に、もし暗号資産が分離課税となった場合、「申告分離（税⾦を⾃分で申告して納める仕組み）と、源泉分離（税⾦をあらかじめ収益から差し引いて納める仕組み）の、どちらを希望しますか？」という設問については、源泉分離を希望した回答が75％を占めていたらしいのですが確かに利益を出したらすぐに使いたいですし私も源泉分離の方がありがたいですがデメリットは手数料などを経費で落とせない点ですね。
On July 18, the Japan Blockchain Association (JBA) submitted a "Request for Tax Reform on Crypto Assets" to the government and also announced the results of a questionnaire survey to consider the tax system. The survey was conducted from April 24th (Thurs) to April 25th (Fri), 2025. The survey targeted 1,500 men and women in their 20s to 60s who live in Japan. Next, in response to the question "If crypto assets were to be subject to separate taxation, would you prefer separate reporting (a system in which you declare and pay your taxes yourself) or separate tax at source (a system in which taxes are deducted from your earnings in advance and paid)?", 75% of respondents said they preferred separate tax at source. I certainly want to use my profits as soon as I make them, so I would prefer separate tax at source, but the disadvantage is that I cannot write off fees and other expenses.
