A discussion has emerged regarding the tax treatment of crypto credit cards in Japan. The debate centers on whether the foreign exchange gains realized during settlement are classified as miscellaneous income and if they fall under the 200,000 JPY exemption threshold for tax declarations. Some traders argue that strict compliance requires tracking all spending events, which could be administratively burdensome. Others suggest that the complexity of calculating rates for various tokens might limit practical enforcement or restrict usage to specific exchange-issued cards.
