The IRS now requires crypto exchanges to report your digital asset transactions. Here’s what you need to know about the new Form 1099-DA—what’s on it, what’s often wrong, and how to stay compliant.
Form 1099-DA (Digital Asset) is a new IRS tax form that cryptocurrency exchanges and brokers use to report your digital asset transactions to both you and the IRS. Introduced in 2025 under Treasury Decision 10000, this form tracks proceeds from sales, exchanges, and dispositions of cryptocurrency and other digital assets. Think of it as the crypto equivalent of Form 1099-B that traditional brokerages use for stock trades.
You’ll receive your first Form 1099-DA by February 17, 2026, covering transactions from tax year 2025. Brokers must furnish forms to taxpayers by this date and e-file with the IRS by March 31, 2026. If you traded on multiple exchanges, expect a separate 1099-DA from each platform.
Centralized cryptocurrency exchanges and custodial platforms classified as “digital asset brokers” under IRS rules are required to send 1099-DA forms. This includes major exchanges like Coinbase, Kraken, and Gemini. Decentralized exchanges (DEXs), self-custodial wallets, and DeFi protocols are currently exempt from reporting requirements following the repeal of the DeFi broker rule in April 2025.
Form 1099-DA contains 16 data boxes including: gross proceeds from sales, cost basis (when available), transaction dates, digital asset type, wallet addresses, transaction IDs (TxIDs), DTIF codes that categorize transaction types, and whether the asset qualifies as a “covered security.” The form also indicates the cost basis calculation method used and flags any wash sale adjustments.
Covered securities are digital assets acquired on or after January 1, 2026, where the broker has complete cost basis information. For these assets, brokers must report your cost basis to the IRS. Uncovered securities are assets acquired before 2026 or transferred from another platform—brokers aren’t required to report cost basis for these. This distinction matters because uncovered assets may show inflated gains on your 1099-DA that don’t reflect your actual tax liability.
This is one of the most common issues with 1099-DA reporting. When you transfer cryptocurrency between wallets or exchanges, the receiving platform often doesn’t know your original purchase price (cost basis). As a result, your 1099-DA may report zero cost basis, making it appear you owe taxes on the entire sale amount rather than just your actual profit. You’re responsible for maintaining accurate records and reporting your true cost basis on your tax return—which may differ from what the 1099-DA shows.
First, don’t panic—discrepancies are common, especially for transferred assets. Review the form against your own records and identify specific errors. Contact the issuing exchange to request a corrected form if the error originated on their end. If you cannot obtain a corrected form, you can still file your taxes using your accurate records. Document everything thoroughly and consider working with a crypto-specialized CPA who can help reconcile discrepancies and ensure proper IRS reporting.
Yes, absolutely. Your tax obligation exists regardless of whether you receive a 1099-DA. Transactions on decentralized exchanges, peer-to-peer transfers, DeFi protocols, and international platforms may not generate 1099-DA forms, but they’re still taxable events. The IRS requires you to report all cryptocurrency gains and losses on your tax return. Failing to report because you didn’t receive a form is not a valid defense and can result in penalties.
Start by gathering 1099-DA forms from every exchange where you traded. Cross-reference each form against your personal transaction records, paying close attention to transfers between platforms that may appear as sales on one exchange without corresponding cost basis. Use crypto tax software to aggregate data from all sources and identify discrepancies. The goal is a complete, accurate picture of your activity—not just what each individual 1099-DA reports.
DTIF (Digital Transaction Information File) codes are standardized identifiers that categorize the type of digital asset transaction reported on your 1099-DA. These codes help the IRS understand whether a transaction was a sale, exchange, payment for goods or services, gift, or other disposition type. Understanding these codes helps you verify that transactions are properly categorized and identify any misclassifications that could affect your tax liability.
Form 1099-DA primarily reports sales and dispositions of digital assets, not income events like staking rewards or airdrops. However, the receipt of staking rewards and airdrops is typically taxable as ordinary income at fair market value when received. These income events may be reported on other forms or require self-reporting. The subsequent sale of those assets would then appear on Form 1099-DA.
Brokers may use different cost basis calculation methods including FIFO (First-In, First-Out), LIFO (Last-In, First-Out), HIFO (Highest-In, First-Out), or Specific Identification. Your 1099-DA should indicate which method was applied. Importantly, you can choose your own cost basis method when filing, but you must apply it consistently and maintain records supporting your calculations. Per IRS Revenue Procedure 2024-28, you’re now required to track cost basis on a per-wallet basis.
Ignoring your 1099-DA is a significant risk. The IRS receives a copy of every 1099-DA issued, and their systems are designed to match reported income against your tax return. Failing to report income shown on a 1099-DA can trigger automated notices, accuracy-related penalties of 20%, and in cases of willful noncompliance, fraud penalties up to 75% of the underpaid tax. Severe cases may result in criminal prosecution.
Yes. If you receive a 1099-DA after filing your return—or discover errors that affect previously filed returns—you can file Form 1040-X to amend. You generally have three years from the original filing date to claim a refund, or two years from when the tax was paid, whichever is later. If the 1099-DA reveals unreported income, filing an amended return proactively is typically viewed more favorably than waiting for IRS enforcement.

Maintain comprehensive records including: original purchase receipts with dates and prices, wallet addresses for all accounts, transaction histories from every exchange and wallet, transfer records between platforms, records of any cryptocurrency received as income (mining, staking, airdrops, payments), and documentation of losses or thefts. Keep these records for at least seven years. This documentation is essential for reconciling 1099-DA discrepancies and defending your position in an audit.
No. Following the congressional repeal of the DeFi broker rule in April 2025 under H.J.Res.25, decentralized protocols and self-custodial platforms are not required to issue 1099-DA forms. This means swaps on decentralized exchanges, liquidity pool transactions, yield farming, and other DeFi activities won’t generate 1099-DA reporting. However, these transactions remain fully taxable—you’re responsible for tracking and reporting them yourself.
When your 1099-DA shows zero or missing cost basis—common for transferred assets—you must determine and report your actual cost basis on your tax return. This requires tracing back to your original acquisition records. Use your own documentation, crypto tax software, or blockchain records to establish what you actually paid. Report your accurate figures on your return, even though they differ from the 1099-DA. Keep thorough records in case the IRS questions the discrepancy.
Form 1099-DA information is reported on your annual tax return, due April 15 following the tax year (or the next business day if April 15 falls on a weekend or holiday). For tax year 2025 transactions, your return is due April 15, 2026. You can file for an automatic six-month extension using Form 4868, but this only extends your filing deadline—not your payment deadline. Estimated taxes on crypto gains are still due quarterly.
For straightforward situations with minimal trading on a single exchange, you may be able to handle 1099-DA reporting yourself using crypto tax software. However, professional help becomes valuable when you have: transactions across multiple exchanges, assets transferred between wallets, DeFi or NFT activity, cost basis discrepancies, international holdings, high transaction volumes, or significant gains. A crypto-specialized CPA can reconcile complex records, optimize your tax position, ensure compliance, and represent you if questions arise.
