WARNING! IRS Has Obtained Records of Bitcoin Buyers and Sellers to Determine if Taxpayers Failed To Report Gains on Their Tax. With only several hundred people reporting their crypto gains each year since bitcoin’s launch, the IRS suspects that many crypto users have been evading taxes by not reporting crypto transactions on their tax returns. And now that like-exchange treatment is prohibited on transactions that occur after 2017, now is the ideal time to be proactive and come forward with voluntary disclosure to lock in your deferred gains through 2017, eliminate your risk for criminal prosecution, and minimize your civil penalties. Don’t delay because once the IRS has targeted you for investigation – even it’s is a routine random audit – it will be too late voluntarily come forward.
