π¨ ATTENTION: The 1099-DA is here!
If you use Coinbase, check your email or log in to your account ASAP. The new IRS Form 1099-DA (Digital Asset Proceeds) is officially landing in inboxes, and you cannot ignore this one.
What you need to know:
The IRS already has a copy: This isn't just an "information" form for you; Coinbase has sent this data directly to the IRS.
The "Cost Basis" Trap: For 2025, many 1099-DA forms only show your Gross Proceeds (the total amount you sold). If you just enter that number without providing your "Cost Basis" (what you paid), the IRS may assume your cost was $0 and try to tax you on the entire sale amount.
Crypto-to-Crypto counts: Even if you didn't cash out to a bank account, those trades from BTC to ETH are on this form and are taxable events.
Don't file your taxes until you've downloaded this form and reconciled it with your records. If you've already filed, you may need to look into an amendment.
