"The IRS is probably unprepared today to endure or to absorb the amount of information that Coinbase alone will be providing," said Lawrence Zlatkin, vice president for tax at the exchange, during a Senate Finance Committee hearing examining the U.S. approach to taxing the crypto sector. The Treasury Department's IRS had recently established the crypto brokerage forms that will deluge the federal tax offices, but there are several major crypto taxation questions still hanging. Some of them — such as whether to ignore any minor gains on small-scale transactions (the so-called "de minimis" exemption) or to delay the taxability of staking gains until they're sold — are at the center of congressional discussions on digital assets legislation. But it remains unclear which ones will get attention and when, leaving significant uncertainty for crypto businesses and investors. "Without clear tax rules, taxpayers are left with many unanswered questions."
