@wakeupsheeps there is a case to be made they should have been providing information reports. Consider that the IRS already provided guidance that digital currencies would be taxed as property, so technically crypto to crypto exchanges such as Poloniex are facilitating barter transactions.
At a minimum they would have been required to provide Form 1099-Bs. TIGTA raked the IRS over the coals for lack of enforcement last September towards cryptocurrency tax evasion issues. The result was one month later, Coinbase got hit with a historic and sweeping "John Doe" summons, which they limited the scope of in an agreement with Coinbase. My guess would be Kraken and Poloniex are next on the enforcement radar.
I appreciate the info, saves me an investigation. It seemed rather odd that government hadn't already stepped into the crypto space. Many untaxed transactions have come and gone.
If I remember correctly, there were about <1,000 people who declared capital gains taxes taken out of coinbase last year. Policy changes afoot.
