[New U.S. Crypto Tax Rules: Exchanges Report Transaction Amounts, Investors Still Need to Calculate Gains and Losses] According to Cointelegraph, the U.S. Internal Revenue Service (IRS) has stipulated that for transactions in 2025, brokers are generally required to report digital asset sales revenue, but in most cases, they are not required to report cost basis. Taxpayers will still need to calculate gains and losses on their own. Starting in 2026, brokers will be required to report the cost basis for eligible digital assets. The IRS also emphasized that even if taxpayers do not receive a 1099-DA form, they are still obligated to report income and gains or losses related to digital assets. During the first tax season in which the 1099-DA reporting rules for crypto assets are applied in the U.S., some investors are facing issues such as missing transaction data and difficulties in verifying cost basis.
