tldr; CEO: "Coinbase and the IRS have (I believe) a shared goal to ensure all U.S. customers pay their taxes. I believe a good option would be to use the same third party reporting mechanism that brokerage firms like Fidelity and Charles Schwab use today: the 1099-B form. We’d ideally like to see that structure applied evenly to all companies in the industry, but even if we’re required to go first, we’re ready to implement 1099-B reporting. With this potential solution, Coinbase (and other virtual currency exchanges) would issue a 1099-B at the end of the year to all U.S. customers, and send a copy to the IRS. This would make it easy for users of virtual currency to pay their taxes without violating their privacy."
