On May 5, 2021, the US District Court for the Northern District of California entered an order authorizing the IRS to serve a John Doe summons on popular cryptocurrency exchange, Payward Ventures Inc. d/b/a Kraken (Kraken). Specifically, the court’s order grants the IRS permission to serve a John Doe summons on Kraken in order to obtain information on US taxpayers who conducted the equivalent of at least $20,000 in total transactions for each year from 2016 to 2020.
