Form 1099-B Filing Deadline for 2026

State filing deadlines for Form 1099-B

Here are the states that require Form 1099-B, along with their deadlines for tax year 2026 filed in 2027:

What happens if you miss the 1099-B filing deadline?

Missing the 1099-B deadline, or filing incorrect information, can result in penalties. The penalty generally depends on how late you file a correct return or furnish a correct statement.

Are Digital Asset Sales Reported on Form 1099-B?

Generally, no. Brokers report digital asset sales effected in 2026 on Form 1099-DA. This includes most digital assets that are also securities. A few exceptions still go on Form 1099-B, such as Section 1256 contracts on digital assets, which are reported on an aggregate basis.

Are Any Transactions Exempt From Form 1099-B Reporting?

Yes. Brokers are not required to file Form 1099-B for certain transactions, including:

• Sales for exempt recipients, such as corporations, charitable organizations, and IRAs
• Sales of money market fund shares
• Sales of fractional shares when gross proceeds are less than $20

Barter exchanges with fewer than 100 transactions during the year are also not required to file.

Can I get an extension to file Form 1099-B?

Yes. Form 1099-B qualifies for an automatic 30-day extension. File Form 8809 electronically or by paper on or before the original due date to receive it. If you need more time to furnish transferor copies, you can request a separate extension with Form 15397.

Tips to Meet the Form 1099-B Deadline

• Reconcile cost basis for covered securities early
  For each covered security sale, report the acquisition date, cost basis, gain or loss type, accrued market discount, and any wash sale loss disallowed. Review this data before January so there is time to fix gaps.
• Follow up on missing transfer statements
  If a required transfer statement does not arrive, request it from the transferring broker. Without a complete statement, you may treat the security as noncovered, but you must file a corrected form if the statement later shows it is covered.
• Separate short-term, long-term, and noncovered sales
  Report covered securities with short-term gain or loss, covered securities with long-term gain or loss, and noncovered securities on separate forms. This applies even when all three were sold in a single transaction.
• Consider a composite substitute statement
  Brokers can combine 1099-B, 1099-DA, 1099-INT, 1099-OID, and 1099-DIV information into a single substitute statement. Follow the IRS substitute form rules in Pub. 1179.
• Build in time for IRIS if you are transitioning from FIRE
  The last day to file through the FIRE system is November 19, 2026. IRIS will be the only e-filing system for information returns during the 2027 filing season. Complete your IRIS setup early so you have time to resolve validation or filing issues before the deadline. Learn More
