E-File Form 1099-B Online for 2025 Tax Year

Electronic filing provides several benefits compared to paper filing:

• Bulk filing capability: Upload thousands of forms at once via CSV or direct integration

The IRS Filing Information Returns Electronically (FIRE) system is the official IRS platform for submitting information returns including Form 1099-B. You can file directly through FIRE or use an IRS-authorized transmitter like BoomTax.

• Direct FIRE filing: Requires creating a FIRE account, obtaining a Transmitter Control Code (TCC), and formatting files to IRS specifications
• Using a transmitter: BoomTax handles the technical requirements, allowing you to submit data through our user-friendly interface
• Testing requirements: New FIRE filers must complete a test submission before filing production returns
• File format: FIRE requires specific ASCII text file formatting with fixed-width fields

Most filers prefer using an authorized transmitter to avoid the complexity of direct FIRE filing. BoomTax validates your data, formats it correctly, and transmits to the IRS on your behalf.

Here is how electronic filing compares to paper filing for Form 1099-B:

For brokerages with more than a handful of transactions, e-filing is the clear choice. The IRS also prefers electronic submissions as they reduce processing errors and speed up matching.

The IRS imposes separate penalties for failure to file electronically when required:

• 10+ returns: You must e-file if you submit 10 or more information returns of any type
• Penalty for paper when e-file required: $60 per form for the first year of noncompliance
• Repeat noncompliance: Penalties increase for subsequent years
• Reasonable cause: The IRS may waive penalties if you demonstrate reasonable cause for paper filing

Beyond penalties, paper filing increases your risk of errors and delays. E-filing with BoomTax ensures compliance with electronic filing mandates.
