1099-DA vs Form 8949: What’s the Difference and How Do They Work Together?
A new form is about to reach a lot of crypto investors, and it is easy to misread what it means. Starting with the 2025 tax year, U.S. brokers began issuing Form 1099-DA for digital asset sales, and if you traded on a U.S. exchange, you may receive one early in 2026. The natural worry follows quickly: is this my tax form now, or do I still have to do something with it?
That question is really about 1099-DA vs Form 8949, two forms that sound similar but do very different jobs. One is a statement a broker sends about you. The other is the form you fill out and file. Getting the relationship wrong is one of the easiest ways to overpay, or to file a return that does not match what the IRS already has on record.
In plain terms, the 1099-DA is information, and Form 8949 is your reporting. Here is what that means for you, why the two are not interchangeable, and how they fit together when you file.
Quick Answer
Form 1099-DA is an informational statement your broker sends to you and the IRS reporting the gross proceeds from your digital asset sales. Form 8949 is the form you complete and file to report each sale, with its cost basis and the resulting gain or loss. The 1099-DA is not a substitute for Form 8949. Instead, you use the 1099-DA together with your own records to complete Form 8949, and its subtotals then flow to Schedule D.
Key Takeaways
- Form 1099-DA reports proceeds; Form 8949 reports gains and losses. The broker files the first about you, and you file the second.
- A 1099-DA does not replace Form 8949. You still report each disposal on Form 8949, even when a broker has sent a statement.
- Most 2025 statements will not show your cost basis. The IRS confirms taxpayers must calculate basis before filing, so your own records still matter.
- Form 8949 reconciles the broker’s numbers with yours, and its short and long term subtotals carry to Schedule D (Form 1040).
- You report digital asset gains and losses whether or not you receive a 1099-DA. A missing form does not remove the obligation.
What Form 1099-DA Actually Is
Form 1099-DA, titled Digital Asset Proceeds From Broker Transactions, is an information return. That is a document a third party, in this case your broker or exchange, files with the IRS to report activity in your account. You get a copy, and the IRS gets a copy at the same time.
According to the IRS, brokers use Form 1099-DA to report proceeds from, and in some cases basis for, digital asset dispositions. You will generally receive one if you used a broker to sell, exchange, or otherwise dispose of digital assets, whether for U.S. dollars, for another digital asset, or in exchange for goods and services. For the 2025 tax year, brokers must furnish your copy by February 17, 2026.
The important word is “proceeds.” For 2025, most 1099-DA statements report what you received when you sold, not what you originally paid. The IRS states plainly that most 2025 statements will not include basis, and that you must calculate basis before you file. Broker basis reporting for certain covered digital assets begins with transactions on or after January 1, 2026, so this gap narrows over time. For now, though, it is real, and it shapes everything that follows.
What Form 8949 Actually Is
Form 8949, Sales and Other Dispositions of Capital Assets, is the form you complete and attach to your return. This is where each individual sale gets its own line: what you sold, when you acquired it, when you sold it, the proceeds, the cost basis, and the gain or loss.
The IRS designed Form 8949 to reconcile the amounts reported to you and the IRS on forms like 1099-B and 1099-DA with the amounts you actually report. In other words, it is the bridge between the broker’s statement and your final numbers. Once you list your transactions, the subtotals carry to Schedule D (Form 1040), where your total capital gain or loss is calculated. For a line-by-line walk through the form itself, our guide on how to report crypto correctly on Form 8949 covers the mechanics.
For the 2025 form, digital asset sales have their own boxes. Short term transactions fall under Part I, using box G when the 1099-DA shows basis was reported to the IRS, box H when it was not, and box I when the sale was not reported to you on a 1099-DA or 1099-B at all. Long term transactions use the parallel boxes J, K, and L in Part II. That structure exists precisely because a broker may report your proceeds without your basis, and the form has to capture which situation applies.
The Core Difference in One View
| Form 1099-DA | Form 8949 | |
|---|---|---|
| Who prepares it | Your broker or exchange | You (or your tax pro) |
| Who it goes to | You and the IRS | Filed with your return |
| What it reports | Gross proceeds, sometimes basis | Each sale, with basis, gain, or loss |
| Its role | An informational statement | Your actual tax reporting |
| Where it leads | Onto your Form 8949 | Onto Schedule D |
The table makes the relationship clear. These are not two versions of the same thing. One is an input, and the other is the report you build from it.
How the Two Forms Work Together
At filing time, the forms connect in a specific order. First, you gather your 1099-DA statements, which tell you the proceeds a broker reported to the IRS. Next, you transfer each sale onto Form 8949, adding the cost basis from your own records where the statement leaves it blank. The IRS notes that the basis of a digital asset is generally its cost in U.S. dollars, including acquisition fees and commissions. Then, with proceeds and basis both entered, Form 8949 calculates the gain or loss on each line, and the subtotals flow to Schedule D.
This order is why reconciliation matters. If the proceeds on your Form 8949 do not match what the broker reported on the 1099-DA, the IRS sees a mismatch. So the goal is not to ignore the 1099-DA, and not to accept it blindly either, but to line it up against your own transaction history and resolve any differences before you file. When a 1099-DA shows basis was reported to the IRS, the IRS instructs you to report that same basis in column (e) of Form 8949.
Why the 1099-DA Does Not Let You Skip Form 8949
It is tempting to assume that once a broker has reported your sales, the IRS has everything it needs. That is not how information returns work. The 1099-DA tells the IRS what you received; it does not tell them what you owe. Only Form 8949, with basis applied, produces a gain or loss. Because 2025 statements largely omit basis, a proceeds-only figure taken at face value would treat your entire sale amount as if it were profit, which almost always overstates the tax. Reporting through Form 8949 is what protects you from that.
There is also the matter of transactions no broker sees. If you moved assets to self custody, used a foreign exchange, or transacted in DeFi, you may not receive a 1099-DA for that activity. The IRS is explicit that you must report all digital asset income, gains, and losses whether or not you receive a form. Form 8949 is where that reporting happens, with or without a matching statement. For the wider shift in broker reporting, see our overview of the 1099-DA era of crypto taxes.
Tax Reporting Requirements
- Form 1099-DA (Digital Asset Proceeds From Broker Transactions) is filed by your broker, not you. Keep it, check it against your records, and use it as a starting point. It applies to digital asset dispositions on or after January 1, 2025.
- Form 8949 (Sales and Other Dispositions of Capital Assets) is where you report each sale, with proceeds, cost basis, and gain or loss, using the digital asset boxes that match whether basis was reported to the IRS.
- Schedule D (Form 1040) aggregates the short term and long term subtotals from Form 8949 into your total capital gain or loss.
- Your own records remain the source for cost basis whenever a 1099-DA does not provide it, which the IRS confirms is the case for most 2025 statements.
Common Mistakes (and How to Avoid Them)
- Treating the 1099-DA as a finished tax form. It is a statement, not a filing, so you still complete Form 8949.
- Reporting proceeds without basis. If you copy the proceeds and leave basis empty, you may report a gain far larger than reality. Fill in basis from your records.
- Assuming no form means no reporting. Self custody, foreign brokers, and peer to peer trades may generate no 1099-DA, yet the gains and losses are still reportable.
- Choosing the wrong 8949 box. Match the box to whether basis was reported to the IRS, so your figures line up with what the agency already has.
How CRPTM Helps
CRPTM is built for exactly this reconciliation. It imports your transaction history from connected exchanges, wallets, and blockchains, and it also accepts an IRS Form 1099-DA upload, so the broker statement and your own records sit in one place. It classifies each transaction, looks up the U.S. dollar value, and applies your chosen cost basis method (FIFO, HIFO, or LIFO). Where a record is incomplete, it flags Missing Purchase History with the exact quantity, and it matches transfers between your own wallets so they are not counted as sales. From there, it generates a pre-filled Form 8949 and Schedule D you can review before filing. CRPTM produces the forms, and you or your CPA file them. It covers U.S. spot trading, and report downloads are available on a paid plan. You can see the reporting features on the CRPTM crypto tax page.
Related Questions / FAQs
Is Form 1099-DA the same as Form 8949?
No. Form 1099-DA is an informational statement your broker sends to you and the IRS about your digital asset proceeds. Form 8949 is the form you complete and file to report each sale with its cost basis and gain or loss. One feeds the other.
Do I still file Form 8949 if I received a 1099-DA?
Yes. The 1099-DA does not replace Form 8949. You use the 1099-DA and your own records to complete Form 8949, and its subtotals carry to Schedule D.
Why is the cost basis missing on my 1099-DA?
For the 2025 tax year, the IRS confirms most statements report proceeds only. Broker basis reporting for certain covered assets begins with transactions on or after January 1, 2026, so until then you supply basis from your own records.
What if I did not receive a 1099-DA?
You still report the transaction. The IRS states you must report all digital asset gains and losses whether or not you receive a form. Self custody, DeFi, and foreign brokers may not generate one.
Where do Form 8949 totals go?
The short term and long term subtotals from Form 8949 carry to Schedule D (Form 1040), which calculates your total capital gain or loss.
What are the new digital asset boxes on Form 8949?
Short term digital asset sales use boxes G, H, and I in Part I, and long term sales use boxes J, K, and L in Part II. They distinguish whether basis was reported to the IRS, was not reported, or the sale was not on a 1099-DA at all.
Does the 1099-DA get filed with my return?
No. You keep the 1099-DA for your records. Form 8949 and Schedule D are what you file, and you reconcile the 1099-DA against your reporting.
Conclusion
The simplest way to hold the difference in your head is this: a 1099-DA is what your broker tells the IRS about your sales, and Form 8949 is what you tell the IRS about your gains and losses. They are partners, not substitutes. The statement starts the process, and the form finishes it, flowing on to Schedule D. Keep your own records close, because for now they are still where cost basis comes from. To see how the wider forms landscape fits together, our Crypto Tax USA 2026 guide maps the full picture.
