Coinbase 1099-DA Tax Forms Explained
Understand your Coinbase 1099-DA forms, what they report, and how they impact your crypto taxes. Learn how to navigate the chaos these forms are causing for investors and exchanges, and how to file easily with Coinbase 𝘅 Koinly this season.
Will Coinbase send a 1099 form?
Yes. Coinbase issues 1099 forms. You may receive a 1099-DA or a 1099-MISC depending on your transactions. Worse still, there’s a strong possibility your 1099-DA form(s) will be incorrect.
Fortunately, Coinbase and Koinly have partnered up to make this tax season simpler.
What’s included in a Coinbase 1099-DA form?
Your Coinbase 1099-DA will include:
Your name, Taxpayer Identification Number (TIN), and your address
Account name and identifiers
The name/code of the digital asset, the type of asset, and the number of assets
The acquisition date and the sale/disposal date
The cost basis of the asset and the proceeds from the transaction
Specific sections for aggregated transactions for stablecoins and NFTs
At a glance, you might notice that your gains/losses look much larger than you expected in your 1099-DA. This is because exchanges, including Coinbase, don’t have to report cost basis this year, so the figures you’ll see on your 1099-DA are your gross proceeds.
What's included in a Coinbase 1099-MISC?
Your Coinbase 1099-MISC reports income from crypto, such as staking rewards. You’ll receive one if you’ve earned more than $600 in rewards throughout the financial year.
Generally, these forms should be far more accurate than 1099-DA forms.
When will Coinbase send 1099-DA?
Generally, 1099 forms are issued by late January or early February. The official deadline for 1099-DA forms to be issued was February 17, 2026.
However, given the complications that the introduction of the 1099-DA form has caused for exchanges, the IRS has clarified that it will not penalize exchanges for issuing 1099-DAs later than this.
Coinbase has issued many 1099-DAs prior to this deadline, but some users may not receive their 1099-DAs until March 19.
Where to download Coinbase 1099 forms
You can download any 1099 form from Coinbase in the taxes section of your account. If the section next to your form says pending, it hasn't been generated yet.
Why is my Coinbase 1099-DA wrong?
Exchanges are not required to report cost basis for your 2025 transactions (for the 2026 filing year). This means your 1099-DA may report your gross proceeds, as opposed to your capital gain or loss
In other words, if you trust your 1099-DA figures, you may over- or under-pay tax. You’ll be able to spot whether this is the case for you in section 1g of your 1099-DA. If this is unknown, then your 1099-DA is reporting your gross proceeds, not your capital gain or loss.
This isn’t the only potential issue with 1099-DA forms. If you’ve transferred your asset on or off Coinbase, the following sections of your 1099-DA may be incorrect/unknown:
1d (date acquired)
1i (wash sale loss disallowed)
6 (short or long-term gain or loss)
Can I amend my Coinbase 1099-DA?
Based strictly on how Coinbase handles Form 1099-DA, what you can fix depends entirely on whether the asset is covered or non-covered.
Covered assets are crypto acquired and held on Coinbase until sold. Starting with tax year 2026 (filed in 2027), Coinbase is required to report both sale proceeds and cost basis for these assets to you and the IRS on Form 1099-DA. You are still responsible for reviewing the form to ensure the reported cost basis is accurate, but this reporting is mandatory for covered assets.
Non-covered assets include:
Crypto acquired before January 1, 2026
Any crypto transferred into Coinbase from an external wallet or another exchange
For these assets, Coinbase is not required to report cost basis to the IRS. On Form 1099-DA, the sale proceeds will be reported, but the cost basis section may show as “non-covered.” You are solely responsible for tracking, calculating, and reporting the correct cost basis on your tax return.
There are, however, some limited options to amend your Coinbase 1099-DA.
Do I need to edit my Coinbase 1099-DA?
No. Despite the fear-mongering from some, you do not need to amend your 2026 Coinbase 1099-DA for transactions from 2025. Following an email pushing users to correct their cost basis, Coinbase itself has confirmed that if you're filing with Form 8949, then you do not need to edit your 1099-DA this tax season.
Coinbase will not report cost basis to the IRS in 2025, regardless of whether you amend your 1099-DA or not. Amending it will not impact your tax return in 2026, and is a waste of time for users, especially in the face of a looming tax deadline following a messy tax season.
Use your preferred crypto tax calculator and file with accurate cost basis calculations from your complete transaction history as usual.
How do I edit my 1099-DA on Coinbase?
You can add missing cost basis details for transactions that have a single tax lot by going to the Add transaction details page:
In the Needs review tab, select the transaction
Choose Add details
Enter the acquisition date and total cost basis
Save
If the cost basis was originally missing and already added, you can edit it in the Modified tab.
For tax year 2025 and earlier, if you update your cost basis, you can request that Coinbase include the updated figures on your 1099-DA for your own use, but it will not be provided to the IRS.
Can I file without my Coinbase 1099-DA form?
It's better to wait until you have your Coinbase 1099-DA to file. This ensures you can check the correct box on your Form 8949 in relation to your Coinbase transactions.
If you've still not received your Coinbase 1099-DA form and you're worried about the tax deadline coming, you can file for an extension, which will automatically give you until October 15 to file.
As ever, you should speak to a crypto accountant in the USA for specific advice.
What do I do if I receive a 1099 form from Coinbase?
If you receive a 1099-DA or 1099-MISC from Coinbase, you should:
Review your details. Check that your 1099 form includes your correct personal details, as well as accurate information about your transactions.
Calculate your taxes using a crypto tax calculator.
Report accurate gains and losses on Form 8949 by selecting the relevant checkbox as to whether your cost basis was or was not reported.
Report income in Schedule 1/C depending on your circumstances.
Keep records. The IRS isn’t likely to audit those actively reporting crypto, but large discrepancies may raise questions.
How do I report my Coinbase taxes to the IRS?
Koinly has partnered up with Coinbase to help tackle the nightmare of IRS crypto tax reporting this year.
Just import your Coinbase transaction history into Koinly via API or CSV, as well as connecting any other exchanges or wallets you use. This lets Koinly calculate your crypto taxes accurately based on your entire transaction history, and track your cost basis across wallets and exchanges to give you more accurate figures than your 1099-DA.
Once everything’s calculated, you can generate tax reports like Form 8949 and Schedule D to compare against your Coinbase 1099-DA and use them when filing your return.
