Form 1099-DA: The Complete Guide for Crypto Traders (2026)

By Chameleon AI · Updated 13 October 2026

For years, crypto traders filed taxes largely on trust: exchanges sent a mix of statements, and the IRS had little to match against. That has changed. Form 1099-DA is the first IRS form built specifically for digital asset sales, and brokers began reporting gross proceeds for transactions made in 2025. The IRS now receives data on your trades directly from exchanges, and your return needs to line up with it. If you filed on extension, your deadline is October 15, 2026, so this is the right time to check your forms. This guide covers what the form is, who sends it, what it shows, how to reconcile it, and what to do when the cost basis is missing. Rules and instructions are updated regularly, so confirm details on the IRS digital assets page.

What Is Form 1099-DA?

Form 1099-DA, "Digital Asset Proceeds From Broker Transactions," is the IRS information return for reporting sales and exchanges of digital assets. It is brand new. Brokers started reporting for dispositions on or after January 1, 2025, so the first forms covered tax year 2025 and arrived in early 2026.

Who issues it. Brokers, which includes centralized exchanges, custodial wallet providers and other platforms that handle sales on behalf of customers. They send one copy to you and file another with the IRS.

What it reports. Mainly your gross proceeds from each sale, swap or other disposal. Where the broker has it, the form can also show cost basis, acquisition date and other details.

How it differs from older forms. Before this, crypto activity often showed up on a Form 1099-B (if the broker treated an asset as a security), a Form 1099-MISC (for certain income such as rewards) or on no form at all. The 1099-DA is designed for digital asset dispositions, but it does not replace every other form. Staking rewards and similar income may still be reported elsewhere, and you remain responsible for reporting everything whether or not a form arrives.

Who Gets a Form 1099-DA?

• Users of US-based exchanges. Platforms such as Coinbase and Kraken fall under broker reporting rules, so customers with reportable dispositions should expect a form.
• Custodians and other brokers. Any business that holds digital assets for you and executes sales can qualify as a broker.
• DeFi protocols. Generally not yet. A separate rule that would have covered decentralized platforms was repealed in 2025, so most DeFi activity does not produce a 1099-DA. The tax on those trades still applies.
• Foreign exchanges. Rules vary. Some foreign platforms with US customers may report and many will not, so do not assume the absence of a form means the absence of a tax obligation.

When you will not receive one: you made no dispositions, you only traded in self-custody wallets or DeFi, your activity was below a reporting threshold (certain stablecoin and NFT transactions have thresholds), or your platform is not treated as a broker. In every one of these cases you must still report your gains and losses.

What Information Is on Form 1099-DA

• Gross proceeds from each disposal. Check how your broker treated fees, because proceeds can be shown after transaction costs.
• Cost basis. Being phased in. For 2025 it may be blank or shown as not reported to the IRS.
• Holding period. Whether the disposal was short-term or long-term, where the broker has the data.
• Fair market value at the time of the transaction, which matters for swaps and for payments made in crypto.
• Dates. The date of the transaction and, where available, the date you acquired the asset.

Treat the form as the broker's view of your activity. It only knows what happened on its own platform, so it may miss purchases you made elsewhere or assets you moved in from a wallet.

The 2025 Basis Reporting Problem

This is the issue that trips up the most people. Many 2025 Forms 1099-DA show gross proceeds but leave the cost basis empty.

Why it happened. Brokers phased the rules in. Reporting proceeds began with 2025 transactions, while reporting basis applies to assets acquired on or after January 1, 2026. Most of what you sold in 2025 was bought before that, so brokers were not required to report its basis to the IRS.

What you must do. Calculate your own cost basis from your records: what you paid in dollars, plus fees, for the specific units you sold. Enter it on Form 8949 using the box that shows basis was not reported on the 1099-DA.

Consequence of ignoring it. If the form shows proceeds and no basis and you report only the proceeds, you effectively report your entire sale as profit. A $10,000 sale of coins you bought for $9,000 would be taxed as a $10,000 gain instead of a $1,000 gain. Missing basis is a reason to do more work, not a reason to skip it.

How to Reconcile Form 1099-DA with Your Return

1. Match each line to your records. Compare every disposal on the form with your own transaction history. Dates, assets and quantities should agree.
2. Handle transfers between exchanges. Moving coins from one exchange to another is not a sale, but it matters. Your basis and acquisition date follow the coins, so track them across the move.
3. Handle wallet-to-wallet moves. Sending coins between wallets you own is not a taxable event. Keep a record showing that you control both addresses.
4. Account for fees. Trading and network fees affect your basis and proceeds. Confirm whether the broker's figures already include them so you do not count them twice.
5. If the numbers do not match. Work out why before you file. Common causes are missing purchases, fees, an unrecorded transfer, or a pricing difference at the moment of trade. Report what is correct and keep notes explaining the difference.

When Form 1099-DA Is Wrong

• Contact the broker. Ask for a corrected form. Brokers can issue a corrected 1099-DA when data is wrong.
• Document the discrepancy. Save screenshots, statements and your own calculations that show what the correct figure should be.
• Report accurately anyway. Do not wait for a correction if your filing date is near. File using the correct figures and keep the support. If the IRS later asks, your records explain the difference.
• Keep records of the dispute. Store emails, ticket numbers and the final response from the broker.

How 1099-DA Connects to Form 8949 and Schedule D

The reporting flow has three steps.

1. Form 1099-DA to Form 8949. Each disposal from your 1099-DA goes on Form 8949 with dates, proceeds and cost basis. The form's checkboxes distinguish digital assets where basis was reported on the 1099-DA, where basis was not reported, and where no 1099-DA was received. Confirm the exact boxes in the current instructions.
2. Form 8949 to Schedule D. Total your short-term and long-term results from Form 8949 and carry them to Schedule D, which nets them into one capital gain or loss. See our guide to Schedule D and crypto for how the lines work.
3. Schedule D to Form 1040. Your net result carries to the capital gain or loss line on Form 1040, and you answer the digital asset question on the front page.

Common Mistakes

• Ignoring a 1099-DA you received. The IRS has a copy. If your return does not account for it, expect a mismatch notice.
• Reporting the same transaction twice. This often happens when you add trades manually and also import the exchange's data. Pick one source per transaction.
• Assuming basis is reported when it isn't. A blank basis does not mean zero basis. Fill it in yourself.
• Not reconciling proceeds with your own records. The form can be incomplete or wrong. Treat it as a starting point.
• Missing foreign exchange forms. If you used a non-US platform that sent you a 1099-DA or similar statement, include it. Many traders forget accounts they stopped using.

What to Do If You Have Many 1099-DA Forms

Do not panic. Most active crypto traders use several platforms and receive several forms. It is normal.

• Consolidate before filing. Put every form and every transaction in one place so you can see the whole year and the connections between accounts.
• Use tax software or a tracker. With dozens of trades across multiple exchanges, a spreadsheet becomes error-prone quickly.
• Consider professional help. If you have DeFi activity, many transfers or large amounts at stake, a qualified tax professional is worth the cost.

Looking Ahead to 2026 and Beyond

• Basis reporting gets more complete. For assets acquired on or after January 1, 2026, brokers are required to report basis, so forms issued in 2027 should be more complete. Older holdings will still depend on your records.
• More brokers will issue forms. As platforms update their systems, coverage should widen and the data should become more consistent.
• DeFi reporting may come back. The current rules leave decentralized activity largely outside the form, but lawmakers and regulators continue to discuss it. Watch for changes.
