Form 1099‑B, “Proceeds From Broker and Barter Exchange Transactions,” is the information return brokerages and barter exchanges use to report transactions in securities, certain commodities, and bartered property or services. The form shows proceeds from sales, the description of the property sold, acquisition and sale dates, cost basis (when reported to the IRS), gains or losses, and certain adjustments or withheld taxes. Brokers send a copy to both the IRS and the taxpayer.
Key takeaways
– Issuers: Brokerages and barter exchanges file Form 1099‑B with the IRS and provide copies to customers who had sales or reportable barter activity during the year.
– Purpose: It documents capital gains and losses that taxpayers must report on their tax returns.
– Where the info goes: The data on 1099‑B is transferred to Form 8949 and summarized on Schedule D (Form 1040).
– Timing: Brokers generally must furnish 1099‑B to customers by February 15 following the tax year (confirm current year dates with the issuer/IRS).
Who needs to file Form 1099‑B?
– Brokers and barter exchanges are required to file Form 1099‑B with the IRS for each reportable transaction and to provide copies to taxpayers.
– Individual taxpayers do not “file” Form 1099‑B with their return; instead, they must use the information on 1099‑B to report sales on Form 8949 and Schedule D.
What is Form 1099‑B used for?
– Reporting proceeds and details of sales of capital assets (stocks, bonds, options, mutual fund shares, certain commodities, etc.).
– Reporting the fair market value of property or services received through bartering activity.
– Informing the IRS of capital gains/losses so the agency can match broker-reported amounts to taxpayer returns.
How to read Form 1099‑B (common boxes and what they mean)
– Payer and recipient information: Issuer’s name and TIN; your name, address, and taxpayer identification number.
– Description (often Box 1a): Identifies the security or property sold.
– Date acquired / Date sold (Boxes 1b / 1c): When you bought and when you sold the asset.
– Proceeds (Box 1d or 2a): Gross sales proceeds — the amount the broker received from selling the asset.
– Cost basis (Box 1e): What you originally paid for the asset (if the broker reports it).
– Gain or loss (Box 2a): Broker’s calculation of gain or loss for the transaction.
– Checkboxes/flags: Indicate whether basis was reported to the IRS and whether a wash sale loss was disallowed.
– Adjustments (box for adjustments): Any broker adjustments that affect gain/loss (e.g., disallowed wash sale amounts).
– Withholding and state info: Any federal/state tax withheld and state tax information.
Note: Different brokers may format details differently or provide supplemental worksheets. Always review all pages and any online transaction statements.
How do you report 1099‑B information on your tax return?
1. Collect all 1099‑B forms and broker statements (confirm totals and cost basis).
2. Separate transactions into categories required by Form 8949:
• Short‑term (held one year or less) vs. long‑term (held more than one year).
• Whether cost basis was reported to the IRS by the broker.
3. Complete Form 8949 (Sales and Other Dispositions of Capital Assets):
• Use Part I for short‑term and Part II for long‑term.
• Use the proper box/code grouping: if the broker reported basis to the IRS, you typically check Box A (short‑term) or Box D (long‑term). If the broker did not report basis, use Box B or E. If you did not receive a 1099‑B, use Box C or F. (See Form 8949 instructions.)
• Report each transaction detail or attach broker statements if allowed (follow current IRS rules).
4. Carry totals from Form 8949 to Schedule D (Form 1040), which summarizes your net capital gain or loss.
5. Transfer the Schedule D results to your Form 1040. If you have a net capital loss, you can generally deduct up to $3,000 ($1,500 if married filing separately) against ordinary income each year; excess may be carried forward.
Practical step‑by‑step checklist when you receive a 1099‑B
1. Compare the 1099‑B to your own records:
• Confirm sale dates, proceeds, and cost basis.
• Reconcile per‑trade worksheets from your broker to the 1099‑B summary.
2. Watch the basis checkbox:
• If the broker reports basis to the IRS, your Form 8949 reporting may be easier but still verify accuracy.
3. Check for wash sale entries or disallowed loss adjustments and understand how they affect basis.
4. If you disagree with basis or other info, contact the broker to request a corrected 1099‑B.
5. If you don’t receive a 1099‑B by mid‑February, contact the broker. If no replacement is provided and it affects filing, consider filing an extension.
6. Prepare Form 8949 and Schedule D (or use tax software that imports broker data).
7. Keep records (trade confirmations, billing statements, dividend reinvestment records) for at least three years, or longer if an issue is likely.
Do I have to report 1099‑B on my taxes?
Yes. You must report the taxable events shown on the 1099‑B on your tax return by entering the transactions on Form 8949 and Schedule D (even though you do not physically attach the 1099‑B to your return — the IRS receives the broker’s copy). Failure to report can trigger IRS notices since the agency receives the broker’s copy.
Is 1099‑B “earned income”?
No. Amounts on Form 1099‑B represent capital gains or losses from the disposition of capital assets or barter‑transaction proceeds. “Earned income” refers to wages, salaries, tips, and self‑employment income. Capital gains are taxed differently and may be subject to preferential long‑term rates.
Filing instructions and deadlines — who files what and when
– Brokers/barter exchanges: Must file 1099‑B with the IRS and furnish recipient copies — generally by February 15 for the prior tax year (confirm current IRS deadlines each year).
– Taxpayers: Report information on Form 8949 and Schedule D when filing Form 1040 by the individual filing deadline (normally April 15; file an extension if needed).
– You do not send the 1099‑B itself with your return, but you must include the Form 8949 and Schedule D details.
Common issues and how to handle them
– Missing 1099‑B: Contact the broker first. If still unresolved near filing time, consider filing an extension.
– Incorrect cost basis or sale date: Request a corrected 1099‑B from the broker (they can issue corrected forms).
– Wash sales: If a wash sale was disallowed, the broker should report the disallowed amount; understand the adjustment to basis for the replacement shares.
– Multiple transactions: Brokers often provide a consolidated 1099‑B and supplemental worksheet or electronic file that tax software can import; reconcile totals to your own trade records.

Fast facts
– Brokers send a 1099‑B to you and the IRS for each reportable transaction (exceptions can apply for some regulated futures and Section 1256 contracts).
– 1099‑B shows proceeds and (when reported) cost basis; commissions generally are not shown on the form.
– Capital losses can offset capital gains; up to $3,000 of excess loss can reduce ordinary income annually, with the remainder carried forward.
The bottom line
Form 1099‑B is a critical document that bridges brokerage records and your tax return. While you don’t file the paper form with your return, you must accurately transfer its information to Form 8949 and Schedule D so the IRS’s records align with your return. Keep detailed trade records, review broker statements carefully (especially basis and wash sale adjustments), and correct any discrepancies with the issuer before filing.
