Yes, Coinbase reports your digital asset sales to the IRS via Form 1099-DA. Starting with tax year 2026, the Form 1099-DA includes both your gross proceeds and cost basis of transactions occurring on or after January 1, 2026, replacing the 2025 form that covered proceeds only. However, transactions involving noncovered assets may still have no basis reported.
Beyond capital gains, Coinbase also reports staking and rewards income above $2,000 for TY 2026 (prev $600) on Form 1099-MISC, and crypto futures and options trading activity on Form 1099-B for trades through Coinbase Financial Markets.
With that reporting picture in mind, this guide covers what Coinbase sends the IRS, how the IRS cross-checks that data against your return, why your 1099-DA can still understate or misstate your actual gain even with cost basis now included, and the three-step process for reporting your Coinbase activity correctly.
Key Takeaways
- Yes. Coinbase reports your crypto transactions to the IRS via Form 1099-DA. This form reports your gross proceeds and, starting in tax year 2026, your cost basis for covered transactions.
- Coinbase also reports staking, rewards, and referral income on Form 1099-MISC with income equal to or more than $2,000 for payments made on or after January 1, 2026. It reports futures trading on Form 1099-B.
- Cost basis on your 1099-DA can still be missing or marked “non-covered” for assets you moved in from another exchange or wallet, you’re responsible for tracking and reporting that yourself on Form 8949 and Schedule D.
How Coinbase Reports to the IRS?
Coinbase’s tax reporting obligations to the IRS depend on what type of activity you engaged in. The table below reflects current IRS reporting requirements for digital asset brokers; confirm thresholds before you rely on them, since IRS transition relief has shifted more than once since the reporting regime was finalized.
Form / Requirement | Status for Tax Year 2026 |
Form 1099-DA for gross proceeds | Required. Applies to every crypto-to-crypto exchange, crypto-to-fiat sale, and any other disposal, including small trades. |
Form 1099-DA for cost basis | Required for tax year 2026 onward. This is the first tax year cost basis appears on the 1099-DA form. Coinbase can only report the basis for assets it has a purchase record for, assets marked “non-covered” won’t have a basis reported even this year. |
Form 1099-MISC, staking, rewards, referral income | Required, once you earn $2,000 or more in 2026 calendar year through staking, airdrops or other crypto rewards. Reported as income even if you never sold the underlying crypto. |
Form 1099-B for futures and securities | Required if you traded futures through Coinbase Financial Markets. |
Backup withholding | Not applied for tax year 2026. IRS Notice 2025-33 extended relief from the 24% backup withholding requirement (Section 3406) through calendar year 2026. |
CARF (Crypto-Asset Reporting Framework) | Not adopted by the US. The IRS achieves comparable domestic reporting through Form 1099-DA instead; cross-border data sharing for US persons currently runs through FATCA treaties, not CARF. |
Note: Coinbase issues tax year 2026 Form 1099-DA no later than the standard March deadline the following filing season, and you’ll get an email when it’s ready to download.
How Does the IRS Track Your Coinbase Transactions?
Form 1099-DA is not the only way the IRS connects your identity to your Coinbase activity. Your account’s KYC data, automated matching against your filed return, and blockchain-tracing tools each add a separate layer of visibility, together, they give the IRS a fuller picture than any single form provides.
KYC and TIN Linked Account Data
Coinbase collects your Taxpayer Identification Number (TIN), such as your Social Security Number or Individual Taxpayer Identification Number (ITIN), during account verification. It then uses this information for TIN matching and reports the relevant tax information to the IRS. As a result, the transactions reported by Coinbase can be tied to your taxpayer identity and compared with the information on your tax return, regardless of which specific tax form contains the transaction details.
Form 1099-DA and IRS Underreporter (AUR) Matching
The IRS uses its IMF Automated Underreporter (AUR) program to compare the information Coinbase reports with the figures on your tax return. The system can cross reference Form 1099-DA, Form 1099-MISC, and Form 1099 B filed by Coinbase against the income and transactions you report. If the figures do not match, the IRS may send a notice asking you to explain or correct the discrepancy.
For example, if Coinbase reports gross proceeds from a crypto disposal on Form 1099-DA but your tax return does not report a corresponding disposal, the mismatch can trigger an automated flag. Similarly, if you report a different amount of gain or loss from the transaction, the IRS may identify the difference during its matching process.
In such cases, the IRS may issue a CP2000 notice proposing an adjustment to your tax liability. A CP2000 is not a formal audit; it allows you to review the reported information and respond before the IRS finalizes any proposed adjustment. In some cases, particularly where the underreported amount is large, the IRS’s AUR program may instead issue a CP2501 notice as the initial notice.
John Doe Summonses
The IRS can also obtain cryptocurrency user records directly from an exchange through a court authorized John Doe summons, rather than relying solely on the information the exchange routinely reports. In November 2016, a federal court in the Northern District of California authorised the IRS to serve a John Doe summons on Coinbase seeking records of US taxpayers who transacted in virtual currency between 2013 and 2015. The summons did not allege that Coinbase itself had done anything wrong.
Coinbase resisted the request for about a year. However, in November 2017, the court ordered Coinbase to comply with a narrower summons covering accounts that had at least $20,000 in any single transaction type in any year during the relevant period. The order affected approximately 14,000 account holders and covered about 8.9 million transactions. Coinbase notified the affected customers in February 2018.
Why Your 1099-DA May Not Match Your Actual Gain?
Your 1099-DA may not match your actual gain because Coinbase can report your cost basis only when it has a record of your purchase. From 2026, cost basis reporting closes part of the gap in 1099-DA that existed in 2025. However, crypto transferred from another exchange or wallet, or acquired before you opened your Coinbase account, may still be treated as non-covered. In these cases, your 1099 DA may show the proceeds without the cost basis, making the reported gain different from your actual gain.
This situation is especially common for active traders who frequently move crypto between exchanges and wallets. For example, Liam, a Coinbase user, bought Ethereum on a different exchange in 2023, transferred it to Coinbase in early 2025, and sold it in 2026 for $40,000. Coinbase’s 1099-DA correctly reports $40,000 in gross proceeds, but because it never received Liam’s original purchase price, it shows no cost basis for that sale. In reality, Liam paid $34,000 in 2023, so his actual gain is $6,000, not $40,000. Without his own records, Liam may have difficulty substantiating the $34,000 basis if the IRS questions the transaction.
As a result, during a CP2000 review, if Liam has entered the value of the token as 0, the IRS will treat the missing basis as 0. This can turn a modest actual gain into a much larger taxable gain, increasing the tax the IRS believes you owe.
Hence, if any part of your 2026 Coinbase activity involves assets you didn’t originally buy on Coinbase, reconcile your own basis records against the 1099-DA before you file, don’t assume the form is complete just because it now includes a cost basis column. KoinX imports your full cross-platform transaction history and fills in the basis gaps Coinbase’s own records can’t cover.
How to Download Your Coinbase 1099-DA and Transaction History?

Common Misconceptions About Coinbase and IRS Reporting
Coinbase reporting rules can create confusion about what the IRS receives and what you still need to report yourself. Understanding these distinctions matters because a 1099-DA does not capture every tax obligation. Here are the most common misconceptions and what the rules actually mean for your crypto taxes.
Coinbase Doesn't Report Anything To The IRS
Coinbase is a US based custodial broker and must issue Form 1099-DA for covered sale and exchange transactions under IRC Section 6045. It also reports staking and rewards income on Form 1099-MISC. Therefore, your Coinbase activity can reach the IRS through multiple information reporting forms, depending on the type of transaction.
My 1099-DA Covers My Full Tax Obligation Now That It Includes Cost Basis
Cost basis reporting starting in tax year 2026 covers only assets for which Coinbase has a purchase record. Crypto transferred from another exchange or wallet may remain non covered, leaving you to supply the basis. You must still calculate your total gains or losses and report them on Form 8949 and Schedule D.
DeFi Is Now Completely Unreportable Since The Broker Rule Was Repealed
The 2025 repeal of the DeFi broker reporting rule removed a reporting requirement from certain DeFi front ends. However, it did not remove your personal tax obligations. You must still report taxable gains, losses, and income generated through DeFi activity on your tax return, even when the platform does not issue an information return.
Only Cashing Out To USD Is Taxable
A taxable event does not require you to convert crypto into US dollars. Under general tax principles, disposing of crypto can trigger a reportable gain or loss. For example, trading Bitcoin for Ethereum on Coinbase or spending crypto directly can create a taxable event, just like selling crypto for USD.
Small Trades Won't Get Noticed
A small transaction is not automatically exempt from reporting or taxation. Coinbase reports gross proceeds for covered transactions, while the IRS can compare that information against your tax return through its Automated Underreporter system. Therefore, assuming small trades will escape reporting can leave unexplained differences between your Coinbase records and your filed return.
How To Report Your Coinbase Trades Correctly?
Correctly reporting Coinbase trades starts with calculating your actual gain or loss rather than relying solely on the proceeds shown on your 1099-DA. Once you have your figures, you can reconcile them with Coinbase’s report and then transfer the final amounts to the required tax forms.
Step 1: Calculate Your Actual Gain Or Loss
Start with your Coinbase transaction history and calculate the gain or loss for each disposal by subtracting your actual cost basis from the sale proceeds. Do not rely on the proceeds shown on your 1099-DA alone, especially for non covered assets where Coinbase may not report the basis.
If you need help with this process, you can use KoinX to integrate your Coinbase statements. It will automatically import and reconcile your transactions. It then calculates your gains and losses using the relevant cost basis, including for assets transferred from other exchanges or wallets, helping you arrive at figures that more accurately reflect your actual taxable gains.
Step 2: Reconcile Your Figures With Your 1099-DA
Once you have calculated your actual gains or losses, compare them with the figures Coinbase reported. If they differ, identify the reason before filing. Common causes include missing basis for non covered assets, transfers between your own wallets incorrectly treated as sales, or differences in the cost basis method used.
Step 3: File Form 8949 And Schedule D
After reconciling the figures, report each taxable disposal on Form 8949 and carry the resulting totals to Schedule D. Keep your transaction records, cost basis documentation, and reconciliation with your tax records. If the IRS AUR system later identifies a discrepancy and sends a CP2000, these records can help you substantiate your reported gain or loss.
Conclusion
Coinbase reports your trades to the IRS through Form 1099-DA, your staking and rewards income through Form 1099-MISC, and your identity through TIN linked KYC data. With cost basis reporting starting in tax year 2026, the IRS now has even greater visibility into your Coinbase activity. However, greater visibility does not always mean greater accuracy. That is because Coinbase may not have the cost basis for non covered assets, leaving you responsible for calculating and documenting it. You must still report your actual gains and losses correctly on Form 8949 and Schedule D.
If you have moved crypto between exchanges or wallets before selling on Coinbase, reconciling your 1099-DA with your actual cost basis becomes especially important. KoinX can help by connecting directly with Coinbase and automating this reconciliation, including the basis for assets transferred from other exchanges or wallets. This can make it easier to identify missing basis information and prepare a more complete record for tax reporting.
Frequently Asked Questions
How Do I Check What Coinbase Has Reported To The IRS About Me?
To check what Coinbase has reported to the IRS about you, download your Form 1099-DA and 1099-MISC, if applicable, from the Taxes section under Documents. These forms show the information Coinbase filed. You can also check your IRS Online Account transcript for information returns filed under your TIN, including Coinbase reports.
Will I Get A Tax Notice If I Traded On Coinbase But Didn't File?
Yes, you may receive a tax notice if you traded on Coinbase but did not report your crypto activity. The IRS can compare Coinbase’s 1099 DA and 1099 MISC data with your tax return. If it finds unreported transactions or income, it may send a CP2000 notice or a CP2501 notice.
Does Coinbase Withhold Tax On My Crypto Trades?
Coinbase does not generally withhold tax on your crypto trades for tax year 2026. IRS Notice 2025 33 extends relief from the 24% backup withholding requirement through calendar year 2026. Backup withholding on digital asset sales is scheduled to begin January 1, 2027, generally when a valid TIN is unavailable.
What Happens If My 1099-DA Doesn't Include Cost Basis?
If your 1099-DA does not include cost basis, Coinbase may have classified the asset as non covered because it lacks the original purchase record. This commonly happens when you transfer crypto acquired elsewhere to Coinbase. You must determine and document your actual basis yourself, rather than assume the reported proceeds represent your gain.
Does Coinbase Report To The IRS If You Didn't Sell?
If you did not sell, Coinbase generally does not report your holdings or transfers between wallets you own as disposals on Form 1099-DA. However, staking and rewards income can still be reportable through Form 1099-MISC once it reaches $2,000 or more for TY 2026, even if you never sell the crypto.
Does Coinbase Report Small Trades To The IRS?
Coinbase reports small trades to the IRS when they involve covered disposals because Form 1099-DA reports gross proceeds without a minimum transaction threshold. This differs from Form 1099-MISC, where the $2,000 threshold applies specifically to reportable rewards income. Therefore, you should not assume small crypto trades escape IRS reporting.
