IRS FIRE System: Filing Information Returns Electronically for 2025/2026

The FIRE (Filing Information Returns Electronically) system has been the IRS's primary platform for submitting information returns electronically for over two decades. Businesses, financial institutions, and third-party transmitters have relied on FIRE to file forms such as 1099-MISC, 1099-NEC, 1099-INT, 1099-DIV, and W-2s with the IRS each year.

However, the IRS is retiring the FIRE system and replacing it with the modern IRIS (Information Returns Intake System). Understanding how FIRE works, the transition timeline, and what steps you need to take is critical to staying compliant and avoiding costly penalties.

What Is the IRS FIRE System?

The FIRE system is a secure, internet-based platform operated by the IRS that allows filers to electronically transmit information returns formatted according to IRS Publication 1220 specifications. Rather than mailing paper forms, businesses upload fixed-width ASCII text files containing payer and recipient data directly to the IRS through the FIRE portal.

The system supports a wide range of information return types, including:

• Form 1099-MISC — Miscellaneous income, rents, and royalties
• Form 1099-NEC — Nonemployee compensation
• Form 1099-INT — Interest income
• Form 1099-DIV — Dividends and distributions
• Form 1099-OID — Original issue discount
• Form 1099-PATR — Taxable distributions from cooperatives
• Form 1099-SA — Distributions from HSAs, Archer MSAs, or Medicare Advantage MSAs
• Form 1099-Q — Payments from qualified education programs
• Form W-2 — Wage and tax statements (filed through SSA's BSO, but related to FIRE workflows)

How Does the FIRE System Work?

Filing through FIRE requires several steps that distinguish it from newer e-filing methods:

1. Obtain a Transmitter Control Code (TCC): Before filing, every filer or transmitter must apply for a TCC through the IRS e-Services portal. This code identifies you as an authorized electronic filer. The application process can take several weeks, so planning ahead is essential.
2. Prepare Publication 1220 formatted files: FIRE requires information returns to be formatted as fixed-width ASCII text files following the exact field positions, lengths, and record layouts specified in IRS Publication 1220. Each file contains transmitter records, payer records, payee records, and end-of-file records in a precise sequence.
3. Upload to the FIRE portal: Log in to the FIRE system with your TCC credentials and upload your formatted file. The system performs initial validation checks and provides a file status — accepted, accepted with errors, or rejected.
4. Monitor file status: After upload, check back within 24–48 hours to confirm your file was accepted. If the file contains errors, you'll need to correct the issues and resubmit before the filing deadline.

Publication 1220: The FIRE File Format

IRS Publication 1220 defines the technical specifications for electronically filing information returns through FIRE. It is updated annually and contains the record layouts, field definitions, and validation rules that every FIRE submission must follow.

Key characteristics of the 1220 format include:

• Fixed-width records: Each record type (transmitter, payer, payee, end-of-payer, end-of-transmitter) has a defined length, typically 750 characters per record, with every field occupying a specific character position.
• Strict field alignment: Dollar amounts, TINs, names, and addresses must be placed in exact column positions. A single misaligned character can cause the entire file to be rejected.
• No header rows or delimiters: Unlike CSV files, 1220 files have no column headers, commas, or line breaks separating fields — it's a continuous stream of fixed-position data.
• Multiple record types per file: A single file contains a hierarchy of records — one transmitter record, followed by payer/payee blocks, closed by summary records.

The complexity of this format is one of the primary reasons the IRS developed IRIS as a more accessible alternative. Many businesses relied on specialized software or third-party transmitters like BoomTax to generate compliant 1220 files rather than attempting to build them manually.

Who Is Required to E-File Information Returns?

The IRS requires any business or organization that files 10 or more information returns in a calendar year to submit them electronically. This threshold applies to the aggregate total across all form types — not per form. For example, if you file 5 1099-NEC forms and 5 1099-MISC forms, you meet the 10-form threshold and must e-file.

Even if you fall below the threshold, the IRS strongly encourages electronic filing for faster processing, fewer errors, and immediate filing confirmation. Businesses that still file on paper face longer processing times and a greater risk of missing critical deadlines.

FIRE System Retirement: What You Need to Know

The IRS has announced that the FIRE system will no longer accept information return filings after tax year 2025. This means the 2026 filing season is the last in which FIRE will be operational. Going forward, all electronic information return filings must be submitted through IRIS or through an IRS-approved third-party transmitter.

Why Is the IRS Replacing FIRE?

• Outdated technology: FIRE was built on legacy infrastructure that cannot support modern security standards or API integrations.
• High barrier to entry: The Publication 1220 format requires specialized knowledge or software, making it inaccessible to small businesses.
• No web-based data entry: FIRE offered no option for manual entry — every submission required a formatted file upload.
• Limited error feedback: Filers often waited days for batch processing results, slowing the correction cycle.

How IRIS Improves on FIRE

The IRS IRIS system addresses each of these limitations:

• Web-based Taxpayer Portal: Small filers can key in returns directly through a browser — no file formatting required.
• CSV upload: Mid-size businesses can prepare returns in spreadsheet format and upload in bulk.
• A2A API: Software providers and large-scale filers can integrate directly with IRIS for automated, high-volume submissions. BoomTax uses the A2A channel to file on behalf of its customers.
• Real-time validation: IRIS checks submissions immediately, providing faster feedback than FIRE's batch processing.
• Modern authentication: IRIS uses IRS-approved identity verification instead of legacy TCC-only credentials.

Still Using Publication 1220 Files? BoomTax Has You Covered

If your payroll or accounting software still generates Publication 1220 formatted files, you don't need to overhaul your entire workflow. BoomTax accepts legacy 1220 file imports through a simple drag-and-drop process:

1. Export your 1220 file from your existing software — the same file you would have uploaded to FIRE.
2. Drag and drop it into BoomTax — the platform automatically parses the fixed-width records and maps them to the correct fields.
3. Review and validate — BoomTax runs TIN verification, checks for formatting errors, and flags any records that need attention.
4. Submit to the IRS — BoomTax converts your data and transmits it through the IRIS A2A system on your behalf, returning filing confirmations for your records.

This means you can keep your existing software, skip the manual reformatting, and let BoomTax handle the FIRE-to-IRIS transition seamlessly.

Important E-Filing Deadlines for 2026

Whether you file through FIRE (for the final time) or through IRIS, the filing deadlines remain the same for tax year 2025:

Recipient Copy Deadline: Monday, February 2^nd, 2026
All information returns must be furnished to recipients by this date.

IRS E-File Deadline (most 1099 types): Tuesday, March 31^st, 2026
This is the deadline for electronically filing information returns with the IRS.

1099-NEC Deadline: Monday, February 2^nd, 2026
Form 1099-NEC has an earlier deadline. Both the recipient copy and IRS filing share the same due date.

W-2 Deadline: Monday, February 2^nd, 2026
Form W-2 filings to the SSA and recipient copies are both due on this date.

Need more time? Submit Form 8809 through BoomTax to request a 30-day extension for the IRS filing deadline. Note that the recipient copy deadline cannot be extended.

Filing Corrections for FIRE Submissions

If you filed information returns through FIRE and later discovered errors, corrections must still be submitted electronically. Common reasons for filing corrected returns include:

• Incorrect dollar amounts on payee records
• Wrong recipient TIN or name — use TIN matching to prevent these errors
• Filing the wrong form type (e.g., 1099-MISC instead of 1099-NEC)
• Missing or inaccurate payer information

BoomTax simplifies the correction process — identify the error, make the change, and BoomTax handles the corrected filing submission through IRIS.

Penalties for Late or Incorrect Information Return Filings

The IRS imposes penalties for failure to file information returns on time or for filing with incorrect data, regardless of whether you use FIRE, IRIS, or a third-party transmitter. For tax year 2025:

• $60 per form if filed within 30 days of the due date (maximum $683,000).
• $130 per form if filed more than 30 days late but by August 1 (maximum $2,049,000).
• $340 per form if filed after August 1 or not filed at all (maximum $4,098,500).
• $680 per form for intentional disregard (no maximum).

Small businesses with gross receipts of $5 million or less qualify for reduced maximums: $239,000, $683,000, and $1,366,000 respectively.
