Odaily Planet Daily News: Brazil's tax authorities will soon summon foreign cryptocurrency trading platforms to ask them to explain their operations and how they work with local service providers. The Brazilian tax authorities are expected to issue a decree this week summoning these companies to provide further information. Unlike trading platforms officially established in Brazil, they are not obliged to report transactions conducted on their platforms. Andrea Chaves, deputy minister in charge of inspections at the Federal Taxation Bureau, said: "What we care about is to first understand how they operate here and whether there are any illegal activities. We are also concerned about Brazilian wealth information that needs to be taxed." (Reuters)
