If you file Form 1099-B for broker or barter exchange transactions, your 2026 compliance calendar matters. Knowing the right deadlines, understanding potential penalties, and planning your filing workflow early can help you avoid costly mistakes and keep customers satisfied.
Form 1099-B reports proceeds from broker and barter exchange transactions. If you are a broker, clearing firm, or operate a barter exchange, this guide will help you prepare for the 2026 filing season with confidence.
What Is Form 1099-B and Who Must File?
Form 1099-B is filed by businesses that report certain sales and exchange transactions. This generally includes brokers, clearing firms, and barter exchanges.
- Brokers and clearing firms that handle sales of stocks, bonds, mutual funds, options, commodities, digital assets when applicable, and other securities.
- Barter exchanges that facilitate trades of property or services among members.
The form reports gross proceeds and, for covered securities, also reports cost basis and whether the gain or loss is short-term or long-term. Copies must go to both the IRS and your customer so they can support their tax return.

Key 2026 Due Dates at a Glance
For 2026, weekends and federal holidays shift the standard filing dates. These are the adjusted deadlines most filers will use for the 2025 tax year reporting cycle.
The recipient statement deadline falls on Tuesday, February 17, 2026 because February 15 is a Sunday and February 16 is a federal holiday. The paper filing deadline moves to Monday, March 2, 2026 because February 28 falls on a Saturday.
If you manage a large customer base, add these dates to your compliance calendar now. Knowing the 1099-B deadline well in advance gives you time to validate data, handle corrections, and respond to client questions.
How the E-file Threshold Affects You
The IRS requires most filers to submit information returns electronically when they file 10 or more returns in aggregate across certain forms during a calendar year. This includes forms such as 1099, 1098, W-2, and others.
This threshold has applied in recent years and is expected to continue for 2026. If your organization is near or above that threshold, plan to efile because paper filing may not be allowed.
The IRS electronic filing system for information returns includes IRIS. You can learn more on the Information Returns Intake System (IRIS) page.
Extensions: Getting More Time
You can generally request an automatic 30-day extension to file Form 1099-B with the IRS by submitting Form 8809 on or before your IRS filing due date. In some hardship situations, a second, non-automatic 30-day extension may also be available if you provide a written explanation.
These extensions apply to filing with the IRS, not to furnishing statements to recipients. Recipient statement deadlines follow separate rules and usually cannot be extended.
Penalties for Late or Incorrect Forms
Failure to file with the IRS on time, failure to furnish recipient copies on time, or submitting incorrect forms can trigger penalties. The penalty amounts are indexed for inflation, but in recent years they have generally followed this pattern.
- Filed within 30 days after the due date: lower per-form penalty.
- Filed by August 1: mid-range per-form penalty.
- Filed after August 1 or not filed: highest per-form penalty.
- Intentional disregard: significantly higher penalty per form, with no maximum cap.
Penalties apply separately for late IRS filing and late or incorrect payee statements. Always check the current IRS instructions for information returns and Publication 1586 for the latest penalty amounts.
Penalty examples
- Example 1: You file 100 Forms 1099-B 20 days late with the IRS. If the “within 30 days” tier applies, your total penalty could be 100 times the lower per-form amount.
- Example 2: You fail to furnish 50 recipient statements by the 1099-B deadline and send them in April. You could owe a separate per-statement penalty, even if your IRS filing was timely.
What to Include on Form 1099-B
Typical data points reported on Form 1099-B include the following.
- Payee name, address, and taxpayer identification number (TIN).
- CUSIP or other security identifier, trade date, and settlement date.
- Gross proceeds, cost basis for covered securities, and adjustments.
- Short-term or long-term classification.
- Federal income tax withheld, such as backup withholding, if any.
- Account number or account numbers for payees with multiple accounts.
Make sure you distinguish covered versus noncovered securities correctly. Cost basis reporting requirements differ depending on that classification.
2026 Filing Checklist and Timeline
October-December 2025: Prepare
- Confirm reportable accounts and instruments, including any digital asset activity that is in-scope under current rules.
- Collect and validate W-9s, and perform TIN matching to reduce CP2100 and CP2100A notices.
- Identify wash sales, corporate actions, and other adjustments that affect basis and holding period.
January 2026: Reconcile
- Lock down year-end data feeds and reconcile proceeds and basis across back-office and clearing systems.
- Draft consolidated 1099 packages if you provide them to clients.
- Set internal cutoffs so you can meet the 1099-B deadline without last-minute scrambles.
February-March 2026: Furnish and File
- Furnish recipient statements by Tuesday, February 17, 2026.
- File with the IRS by March 2 if filing by paper or March 31 if filing electronically.
- If necessary, submit Form 8809 before your IRS filing deadline to obtain an extension to file with the IRS.
April-August 2026: Corrections
- Process client change requests and data corrections promptly.
- File corrected forms as soon as errors are identified because earlier corrections can reduce penalties.
Practical Scenarios
Scenario A: Retail Broker with Consolidated 1099s
You provide a consolidated statement that includes Forms 1099-DIV, 1099-INT, and 1099-B for each client. You aim to send all recipient packages by the 1099-B deadline, so because February 15 falls on Sunday and February 16 is a holiday, you schedule print and e-delivery for Tuesday, February 17, 2026.
You then e-file all forms on March 20, comfortably ahead of the March 31 IRS deadline.
Scenario B: Barter Exchange
You facilitate member-to-member trades. After reconciling each member’s annual trade proceeds, you prepare 1099-B statements and use e-delivery, with proper consent, for most members to meet the February 17 recipient deadline.
You then e-file with the IRS on March 31.
Scenario C: Missed Deadline
You discover on March 10 that recipient statements were not furnished. Furnish them immediately and document the reason for the delay.
File with the IRS electronically by March 31 to avoid additional filing penalties. You should expect a separate penalty for late recipient statements and may consider reasonable cause relief if the facts support it.
Avoid These Common Mistakes
- Waiting until February to reconcile basis or corporate actions. Start in Q4 to protect the 1099-B deadline.
- Overlooking TIN mismatches. Use the IRS TIN Matching Program where available to reduce “B” notices and backup withholding issues.
- Forgetting state requirements. Some states require direct filing even if you participate in Combined Federal/State Filing (CF/SF), so verify each state’s rules.
- Sending recipient statements by email without consent. Obtain and document e-delivery consent correctly.
- Ignoring wash sales and other adjustments. Incorrect basis reporting can lead to client complaints and amended forms.
Actionable Tips for a Smooth Filing Season
- Lock in your print and e-delivery schedules by mid-January and build in a quality-control buffer before the 1099-B deadline.
- Centralize data such as trades, transfers, and corporate actions, and assign owners for each input to reduce reconciliation risk.
- Adopt e-file early, even if you are under the threshold, to reduce errors, speed acknowledgments, and avoid paper mail delays.
- Draft client communications that explain common variances, such as wash sales, basis for DRIPs, and corrected statements, so call volumes stay manageable.
- Create a corrections playbook that defines when to issue a corrected 1099-B versus when to answer a client inquiry without reissuing the form.
- If you anticipate delays, submit Form 8809 before the IRS filing due date. An extension of time to file with the IRS does not extend the recipient 1099-B deadline.
Frequently Asked Questions
Is cost basis always required on Form 1099-B?
For covered securities acquired after applicable effective dates, yes. Brokers must report basis and short-term or long-term status. For noncovered securities, basis reporting to the IRS is not required, although brokers may still provide it to customers for convenience.
What if a client refuses to provide a TIN?
You may need to begin backup withholding at the applicable rate and still file and furnish Form 1099-B. Keep documentation showing your solicitations for the TIN, such as Form W-9 requests.
How do state filings work?
Many states receive 1099 data through the IRS Combined Federal/State Filing program, but not all do. Some states require direct filing, separate due dates, or additional data, so confirm each state’s requirements every year.
Bottom Line
For 2026, the most important dates are February 17 for recipient statements, March 2 for paper IRS filing, and March 31 for electronic IRS filing. Build your timeline backward from the 1099-B deadline, validate data early, and use e-file to minimize risk.
