[Deadline for Extended Tax Filing for U.S. 2025 Tax Year is October 15, Crypto Traders Must Verify Filing Information] According to Crowdfund Insider, the extended filing deadline for individual federal income taxes for the U.S. 2025 tax year is October 15. The IRS specifies that this deadline applies to taxpayers who have previously applied for an extension and is not a new deadline specifically for crypto assets. The extension only prolongs the filing period, not the payment period. For digital asset transactions in 2025, brokers may provide Form 1099-DA, which might not include cost basis information. Taxpayers are still required to calculate related gains or losses themselves and file accordingly as per regulations.
