Starting with the 2025 tax year, Coinbase is required to issue IRS Form 1099-DA to all U.S. customers.
This new form will standardize gross proceeds and cost basis reporting from the sale and exchange of crypto. Coinbase will provide tax year 2026 Form 1099-DA to you no later than mid-February 2027 and you will receive an email when it is ready for download.
Keep in mind
Gross proceeds reflect the cumulative amount received from all asset dispositions, including sales or exchanges. This is not your net gain or balance, but the total value from all transactions, including small trades.
For tax reporting purposes, a sale includes:
Crypto-to-crypto exchanges (Example: exchanging Bitcoin for Ethereum)
Crypto-to-fiat exchanges (Example: converting Bitcoin to USD)
Any transaction where you receive an amount from the sale or exchange of an asset
When sending crypto, you may incur a network fee. Only the crypto sold or used directly to pay for this network fee is reported on Form 1099-DA. The rest of your send (the amount you transfer to another wallet or address) is not reported on Form 1099-DA.
If an asset is marked as non-covered on your Form 1099-DA, the acquisition of the digital asset does not meet the IRS requirements for Coinbase to report cost basis to the IRS
Coinbase uses Eastern Time for tax reporting. If your trade occurred after midnight ET on Jan 1, 2027, it will be on your tax year 2027 Form 1099-DA, not your tax year 2026 Form 1099-DA.
Cost basis reporting
For tax year 2026, Form 1099-DA will include both proceeds from the sale or exchange of your crypto assets and cost basis information.
Crypto tax software and conflicting basis
Crypto tax software can help you track and report cost basis across multiple accounts and wallets. Records from that software may not match covered or noncovered cost basis on your Form 1099-DA. A difference does not always mean something is wrong or that you need a correction. You must file an accurate return and keep records that support it. If your records differ, check your provider’s guidance and talk to a tax professional.
Depending on the types of transactions you’ve made, you may choose to review and edit the cost basis details for your transactions in Coinbase Taxes so your records remain accurate. This is completely optional, and the cost basis you provide is noncovered and will never be reported to the IRS.
Wash Sales
The wash sale rule under IRS Section 1091 does not currently apply to crypto, as it only applies to stocks, bonds, mutual funds, and ETFs. This may change. Please consult a tax professional for specific questions regarding the tax treatment of your transactions.
Correct information on your form 1099-DA
If the name, social security number, or state listed on the Form 1099-DA provided by Coinbase is incorrect, contact our support team to request a correction.
Note: Coinbase can only issue a corrected 1099-DA if there is a change in state residency - no other address changes apply.
Coinbase and/or affiliates do not provide tax advice. Consult a tax professional for specific questions regarding the tax treatment of transactions.
