Form 1099-B Deadlines (2026): Feb 15 Recipient, Mar 31 E-file

Form 1099-B has three key deadlines for reporting tax year 2025 transactions:

Weekend/Holiday Rule: When a deadline falls on a Saturday, Sunday, or federal holiday, the due date moves to the next business day.

For the complete calendar of all information return deadlines, visit our Form 1099-B Filing Deadlines.

Brokers must furnish Copy B of Form 1099-B to recipients by February 15th. This gives account holders time to use the information when preparing their tax returns.

• Delivery methods: Mail, electronic delivery (with recipient consent), or online account access
• Electronic consent: Recipients must affirmatively consent to receive electronic statements
• Combined statements: Many brokers provide 1099-B as part of a consolidated tax statement
• Corrected forms: If corrections are needed, furnish corrected copies as soon as possible

Recipients need Form 1099-B information to complete Form 8949 and Schedule D on their individual tax returns. Late delivery may cause recipients to file extensions or amend their returns.

The IRS filing deadline depends on whether you file by paper or electronically:

• Paper filing deadline: February 28th. Submit Copy A to the IRS with a transmittal Form 1096.
• Electronic filing deadline: March 31st. E-file through the IRS FIRE system or an authorized e-file provider.

Mandatory E-Filing: If you file 10 or more information returns of any type, you must e-file. This threshold dropped from 250 forms in prior years.

E-filing provides an extra month compared to paper filing, reduces errors through validation, and offers faster confirmation from the IRS.

Yes, you can request an extension using Form 8809, Application for Extension of Time to File Information Returns.

• Automatic extension: Form 8809 provides an automatic 30-day extension for filing with the IRS
• Additional extension: One additional 30-day extension may be granted under certain circumstances
• Recipient deadline: Extensions for IRS filing do not extend the recipient copy deadline (February 15th)
• File early: Submit Form 8809 before the original due date

An extension to file does not extend the time to furnish copies to recipients. You must still provide recipient copies by February 15th unless you receive a separate extension for payee statements.

If you miss the Form 1099-B deadline, file as soon as possible to minimize penalties. The IRS assesses penalties based on how late you file:

• File immediately: Even late filing is better than not filing at all. Penalties increase over time.
• Correct errors promptly: If you discover errors after filing, submit corrected forms right away.
• Document your efforts: Keep records of when you attempted to file and any issues encountered.
• Request penalty abatement: If you have reasonable cause, you may request that the IRS waive penalties.

Reasonable cause for penalty abatement includes natural disasters, serious illness, death in the family, or inability to obtain necessary records. The IRS evaluates each request individually based on the facts and circumstances.

The IRS imposes penalties for late, incorrect, or missing Form 1099-B filings. Penalty amounts for tax year 2025 returns (filed in 2026):

Small Business Exception: Businesses with gross receipts of $5 million or less have lower maximum penalties.

Penalties apply separately for failure to file with the IRS and failure to furnish copies to recipients. For detailed penalty information, see our Form 1099 Penalties Guide.

The following entities must file Form 1099-B:

• Brokers: Any person acting as an agent to sell stocks, securities, commodities, or regulated futures contracts
• Barter exchanges: Organizations whose members exchange property or services
• Regulated futures merchants: Dealers in regulated futures contracts, foreign currency contracts, or Section 1256 options

For covered securities, brokers must report all transactions regardless of dollar amount. There is no $600 threshold like other 1099 forms. For more details, see What is Form 1099-B?

Electronic filing offers significant advantages over paper filing for Form 1099-B:

For brokerages with high transaction volumes, e-filing is essentially mandatory. The IRS requires electronic filing if you submit 10 or more information returns of any type.

Many states require Form 1099-B filings in addition to federal requirements. State deadlines and requirements vary:

• Combined Federal/State Filing (CF/SF): Some states participate in the IRS program that automatically forwards federal filings to the state
• Direct state filing: Other states require separate submissions
• State deadlines: May differ from federal deadlines
• State withholding: Report any state tax withheld in Boxes 14-16

Check with your specific state tax authority for requirements. BoomTax supports state filing for all participating states.
