OKX US and the separate global OKX product are not interchangeable for this question.
For the 2025 tax year, OKX says the OKX US product issues Form 1099-DA for reportable sales and crypto-to-crypto exchanges and sends the information to the IRS.
That policy does not automatically describe every global OKX account.
If you are comparing a form with your records, start by identifying the product, then check each reported disposition rather than treating the form as your complete gain calculation.
Does OKX US issue a 1099-DA for 2025?
Yes. OKX says that digital asset brokers, including OKX, report gross proceeds from reportable digital-asset dispositions beginning January 1, 2025, and share a copy with the IRS. Its US tax-form materials identify crypto-to-fiat transactions and crypto-to-crypto transactions as the relevant transaction types for this discussion.
OKX's Crypto Tax Reporting page supplies that issuer statement for the 2025 tax year.
The product distinction matters. The statement concerns OKX US tax-form treatment, not a blanket promise about an account on the separate global OKX platform. It also says what OKX reports as its policy; it is not an independent conclusion about registration, completeness, or accuracy.
A crypto-to-crypto exchange belongs in your review even when no dollars reached your bank. For example, an OKX US export showing a 2025 exchange from one digital asset into another should be compared with the form's proceeds information alongside ordinary crypto-to-fiat sales.
Where and when to find the form
Under the 2025 account flow, sign in to the OKX US account, open Tax Center, select the 2025 tax year, and open tax forms to download Form 1099-DA if it is available. Treat this as the account path for locating the document, not as a guarantee that every account displays a downloadable form.
The IRS furnishing deadline for 2025 Form 1099-DA statements was February 17, 2026 (current figure at the IRS). The deadline is separate from the steps used to look for the document inside OKX US. The IRS Instructions for Form 1099-DA provide the deadline and form instructions.
If Tax Center does not show the expected document, save the screen or account record showing what you found, then compare your exported activity before contacting tax support. Do not replace the OKX US product with the global product while searching.
What the form reports, and what it leaves out
For 2025, the stated OKX US triggers are crypto-to-fiat sales and crypto-to-crypto transactions. The issuer statement centers on gross proceeds. OKX's materials also state that cost basis is not required for the 2025 form.
The later phase-in is narrower than a general promise of basis on every form. OKX says its 1099-DA adds cost basis for covered crypto acquired on OKX in tax year 2026 and sold on OKX in 2026 or later. Gross proceeds continue to be reported for covered sales.
OKX's Tax Center General FAQ describes that 2026 rule.
That means a 2025 OKX US form can be useful evidence of proceeds while still leaving you to locate acquisition records. A form line for an exchange does not, by itself, supply the full history needed to calculate gain or loss.
What to check against your records
Begin with the 2025 OKX US export. Isolate sales and exchanges, then compare the transaction date and proceeds shown in your history with the corresponding information on Form 1099-DA. A worked record scenario might show an OKX US exchange export with a 2025 crypto-to-crypto transaction while the form lists proceeds for that disposition.
The two records should be tied to the same event before you decide that a number is wrong.
Transferred-in assets need a separate mark. Under the IRS Form 1099-DA instructions, crypto transferred into the broker from elsewhere is noncovered. If you later sell it through OKX US, basis-related boxes do not have to be completed for that noncovered asset.
Keep the original purchase record, transfer evidence, and any related exchange history. The reviewed OKX material does not state whether OKX voluntarily supplies that missing basis.
Use this comparison table while working through the export:
| OKX US event | 2025 1099-DA treatment stated in research | Record to compare |
|---|---|---|
| Crypto-to-fiat sale | A reportable 2025 disposition under OKX's stated policy, with gross proceeds reported | OKX US transaction export, sale date, asset, and proceeds |
| Crypto-to-crypto exchange | A named 2025 trigger under OKX's stated policy | The exchange record and the form line tied to that disposition |
| Transferred-in asset later sold | The transferred asset is noncovered under the IRS instructions, so basis-related form boxes need not be completed | Original acquisition record and transfer history outside OKX |
| Event not established in the OKX dossier | The reviewed materials do not establish treatment for that event | The exact transaction record and current OKX tax-support response |
Form-versus-record checklist
- Select the 2025 tax year.
- Confirm that the issuer and product are OKX US and that the document is Form 1099-DA.
- Compare sale and exchange dates and proceeds with the exported OKX US transactions.
- Mark every asset transferred into OKX US and locate its original acquisition record.
- Record the exact discrepancy, including the transaction ID or source record, before using OKX tax support.

Other forms and who receives which document
Use this decision aid without assuming that a different form fills an information gap:
- Are you using OKX US? If so, a documented 2025 sale or crypto-to-crypto exchange means Form 1099-DA is expected under OKX's stated policy. If there is no documented qualifying disposition, the reviewed materials do not establish which document to expect.
- Are you using the separate global OKX product? Do not apply the OKX US policy automatically. The reviewed dossier does not establish the document for that account.
If the asset was transferred into OKX US before a later sale, the form question and the basis question are separate. The dossier does not document another form, an account-specific exclusion, or a threshold that would let you infer a different document.
Corrections and support
Take a record-first approach. Identify the exact transaction, date, and figure that differ. Retain the OKX export, the form, and the outside acquisition record if the asset came from another platform or wallet.
Then use OKX's current tax-support destination with that evidence in hand. The reviewed issuer material does not provide a specific correction workflow, button, deadline, or guaranteed result. A precise support request is more useful than a general message saying that the form looks wrong.
For a transferred-in lot, state that the original acquisition record is outside OKX and ask how the account's document should be read. Keep your own records even if support responds.
What this means for your filing
Treat the OKX US 2025 Form 1099-DA as a starting record for reported proceeds, not as a complete gain or loss calculation. That is especially true when the asset arrived at OKX US from elsewhere or when the transaction involved a crypto-to-crypto exchange.
The practical sequence is simple: identify the US product, download or locate the 2025 form, export the related activity, and match each sale or exchange. If basis is missing, use your original acquisition records rather than assuming the form's blank basis information means the asset had no basis.
For the general method of reconciling missing basis, see reconcile missing cost basis. Once the records are reconciled, report reconciled sales on Form 8949 covers the separate filing mechanics. This page does not determine an individual return position.
Questions about OKX US's form
Is my OKX US account the same as an OKX global account?
No. OKX US is the product addressed by the stated 2025 1099-DA policy, while the global OKX product is separate. Do not extend the OKX US form policy to a global account without account-specific documentation.
Does OKX US send my 2025 crypto sales to the IRS?
OKX says it issues Form 1099-DA for reportable 2025 dispositions and sends the information to the IRS. The stated coverage includes the OKX US tax-form context and does not establish that every global OKX account receives the same treatment.
Will a crypto-to-crypto swap show up, or only a sale for dollars?
The dossier names both crypto-to-fiat transactions and crypto-to-crypto transactions as 2025 trigger types. Compare the exchange export with the form instead of checking only for transactions that produced US dollars.
How will I know whether the basis on my transferred coins is right?
A transferred-in asset is noncovered under the IRS Form 1099-DA instructions, so basis-related form boxes do not have to be completed for it. Compare the form with the original acquisition and transfer records, and do not assume that OKX voluntarily supplied a basis figure.

Next steps
Identify whether the account is OKX US, export its 2025 transactions, and complete the form-versus-record checklist. Then use the general cost-basis or filing guide only after you have marked the sales, exchanges, and transferred-in assets that need separate records.
