Between Feb and March, an income tax return has to be filed In Japan. However, the situation is a little different this year since the government is desperate to take away your money created by virtual currency trading.
Just recently, the government has announced a solid framework of taxes on virtual currency (VC) trading. According to the information, not only does the tax rate go up to 55% maximum, but every single transaction including exchange and settlement will be imposed a tax.
I don't own VCs and am not planning to do so either, but I was asked to do some research on that (how the tax is gonna be like) by my friends.
I put together some info about it. If you wanna know how it looks like in Japan, visit the web below.
