Odaily Planet Daily News Bithumb issued an announcement that it has issued a preliminary notice of comprehensive income tax to some users who participated in events held between 2018 and 2021, and announced its full support for the relevant tax amount. The National Tax Service of South Korea takes the position that remuneration paid to users through various activities (including virtual assets) is taxable income. Bithumb disagrees with the National Tax Service, but explains that taxation is mandatory. The National Tax Service notified 10,700 Bithumb users of 20.2 billion won in event rewards totaling 83.3 billion won, and plans to notify users of approximately 19 billion won in additional taxes as comprehensive income tax. According to Bithumb's calculations, this tax amount is expected to reach 40 billion won. Bithumb announced that it will determine the exact tax amount through full communication and discussion with users, and prepay the amount to the National Tax Service on behalf of users. In addition, we also provide tax consulting services and appeal procedures for comprehensive income tax through tax experts who specialize in providing answers to individual users. In addition, Bithumb said it is currently filing a tax appeal against the National Tax Service’s handling of other income withholding taxes.
