Tax News on 28th February reported that Coinbase, a virtual currency wallet and virtual currency exchange service provider, has confirmed it will soon transmit information on the transactions of 13,000 customers to the IRS, as a result of an earlier court ruling. The case follows a December 2016 summons received by the company from the IRS, which demanded that Coinbase produce a wide range of records relating to approximately 500,000 Coinbase customers, which it fought in court. After a long process, the Court issued an order providing that Coinbase should produce only certain limited categories of information from the accounts of approximately 13,000 customers.
