Form 1099-DA Explained: What Crypto Investors Need to Know in 2026

Form 1099-DA Explained: What Crypto Investors Need to Know in 2026

Short answer: Form 1099-DA is the IRS information return brokers use to report proceeds from digital-asset dispositions and, for certain covered assets, basis information. Receiving the form does not replace your own records: you still need to reconcile basis, transfers, wallet activity, and other taxable transactions before filing Form 8949 and Schedule D when applicable.

The IRS now publishes a dedicated Understanding your Form 1099-DA page and 2026 Form 1099-DA instructions. The IRS says taxpayers must report digital-asset income, gains, and losses whether or not they receive a Form 1099-DA.

What does Form 1099-DA report?

For 2026 and later broker reporting, the IRS instructions require gross-proceeds reporting for digital assets and basis reporting for covered securities, while basis reporting for noncovered securities can differ. A transferred asset can therefore arrive at a broker without the broker having the complete historical basis you need for your return.

1099-DA reconciliation checklist

1. Match each reported disposition to your own transaction history.
2. Confirm whether the asset is reported as covered or noncovered.
3. Compare reported proceeds with your records.
4. Reconstruct missing basis for assets transferred between wallets or brokers.
5. Identify activity outside the broker—such as self-custody or DeFi—that still belongs on the return.
6. If information is incorrect, request a corrected form from the issuer and keep the correspondence, following IRS instructions.
7. Use the reconciled data to complete the appropriate return forms and schedules, including Form 8949/Schedule D where applicable.

Crypto Tax Made Easy also maintains a Form 8949 guide.

What Form 1099-DA Is

Form 1099-DA is the IRS's new reporting form for digital asset transactions. Starting in 2026, centralized exchanges are required to issue a 1099-DA to every customer who had reportable transactions during the prior year — and to send a copy of that form to the IRS.

This is not new in concept. Brokerages have been doing the same thing for stock trades via Form 1099-B for decades. What's new is that crypto now falls under the same reporting framework.

The final digital asset broker regulations, published by the Treasury under the authority established in the Infrastructure Investment and Jobs Act, define "digital asset brokers" to include centralized exchanges — Coinbase, Kraken, Gemini, and others. The regulations took effect for transactions beginning January 1, 2025, meaning the first 1099-DA forms were issued in early 2026 for 2025 transactions.

Each 1099-DA shows: the proceeds from sales and exchanges of digital assets, the cost basis the exchange has on file for those assets, and the gain or loss as calculated by the exchange.

The IRS receives the same information. When you file your tax return, they already have a number to compare it against.

Who Gets a 1099-DA and What It Requires You to Do

If you made any of the following moves on a centralized exchange during 2025, you received a 1099-DA:

• Sold crypto for U.S. dollars
• Traded one cryptocurrency for another
• Used crypto to purchase goods or services on a platform that reports as a broker

Simply holding crypto — buying and not selling — doesn't trigger a 1099-DA. But it does require you to answer "yes" to the digital asset checkbox on page 1 of Form 1040. That checkbox has been on the form since 2019 and the IRS takes it seriously.

Once you have a 1099-DA, the obligation is clear: every transaction reported on that form needs to appear on your tax return. Specifically on Form 8949 and Schedule D.

Form 8949 is where you report individual capital asset transactions — the date acquired, the date sold, the proceeds, the cost basis, and the resulting gain or loss. Each transaction on your 1099-DA gets its own line on Form 8949.

Schedule D aggregates those lines into short-term gains (assets held 12 months or less, taxed as ordinary income) and long-term gains (assets held more than 12 months, taxed at the preferential capital gains rate).

If you had 200 transactions last year, you have 200 lines on Form 8949.

What Happens If You've Never Reported Crypto Gains

If you transacted on a centralized exchange in prior years, those exchanges may also have reported data to the IRS under earlier compliance requirements. But starting with 2025, the 1099-DA makes the reporting systematic and comprehensive.

Here's the sequence if your prior returns didn't include crypto gains and the IRS now has 1099-DA data:

The IRS matches returns against information documents they've received. When your return doesn't include Schedule D entries that correspond to 1099-DA proceeds the exchange reported, they issue a CP2000 notice. A CP2000 is a proposed additional tax assessment — not a final bill, but a letter saying "we think you owe this amount" with a deadline to respond.

The CP2000 will assign zero cost basis to any transactions they can't match to your return. Zero basis means the full proceeds are treated as gain.

The statute of limitations for the IRS to assess additional tax is generally three years from the date you file your return. If you didn't file a return reporting the gain, the statute doesn't start running. Unfiled returns have no limitation period.

Voluntarily amending prior returns before receiving a CP2000 is almost always better than responding to a notice after the fact. The IRS views proactive correction more favorably than a response to enforcement action.

The Cost Basis Problem: What To Do When the 1099-DA Looks Wrong

The 1099-DA your exchange sends you is based on the information the exchange has in its records. That information may not be complete.

If you transferred coins from another exchange or a hardware wallet into the exchange you ultimately sold from, the receiving exchange may have recorded the transfer date as the acquisition date — not the original purchase date. That means the basis they show could be wrong, and the cost basis they reported to the IRS could be wrong.

The IRS receives the same 1099-DA data you do. If your records show a different and correct cost basis — because you can document when and at what price you originally purchased the coins — you are not locked into the exchange's figure.

Under IRS Rev. Proc. 2024-28, taxpayers can use a specific identification method to designate which lots are being sold, provided the identification is made at the time of the transaction. For transactions where you can substantiate the original acquisition price and date through exchange records, purchase confirmation emails, or blockchain transaction history, a crypto CPA can document the correct basis and attach a supporting statement to your return or your CP2000 response.

This is important: the documentation needs to be specific. "I paid more for these coins" is not sufficient. You need the acquisition date, the acquisition price, and the source of that information — an exchange record, a wallet address and transaction hash, a purchase receipt.

What To Do Now

If you have a 1099-DA for 2025 and you haven't filed yet:

Pull every transaction record from every centralized exchange where you traded. Most exchanges offer a CSV export of your full transaction history.

Match those records to your 1099-DA. If the basis shown on the form is wrong because coins were transferred in from another source, gather the documentation for the correct basis.

Report every transaction on Form 8949. Short-term and long-term are reported separately.

If you have transactions across multiple exchanges and multiple wallets, consider working with a crypto tax specialist. The basis reconciliation is not difficult in concept — it becomes complicated at volume.

If you haven't reported prior years and you received 1099-DA forms or prior-year exchange reports, talk to a crypto CPA before the IRS contacts you. Proactive disclosure is a different conversation than CP2000 response.
