What the form is
Under final IRS regulations, crypto brokers, such as exchanges that hold your coins for you, report your sales and exchanges on Form 1099-DA. You get a copy, and the IRS gets the same information.
What it shows for 2025 and for 2026
- Transactions on or after January 1, 2025: gross proceeds, meaning what you sold for.
- For 2025 forms, the IRS will not penalize brokers that make a good-faith effort to file and furnish them, so some 2025 forms may have gaps or errors.
- Transactions on or after January 1, 2026: brokers must also report your basis on certain transactions. Basis reporting generally covers crypto you acquired in that same broker account from 2026 on. Coins you bought elsewhere and transferred in usually show no basis.
If the form does not match your records
Report your sales from your own records. Form 8949 lets you report the correct basis and explain differences from a broker statement, and its instructions for the year list how.
One known source of mismatches: IRS relief lets you identify which units you sold in your own books for 2025 and 2026 (see our cost basis guide). That relief does not change what the broker reports, so the acquisition dates and basis on a 2026 Form 1099-DA may differ from yours.
What to do now
- Expect a Form 1099-DA from each broker you sold through, early in the following year.
- Download your full transaction history from every exchange and wallet, not only the 1099-DA.
- Match transfers between your own accounts, so coins moved in keep the basis you paid originally.
- Keep copies of the forms with your return records.
