How it works

Convert a FIRE file to IRIS XML in three steps

  1. 1
    Add your FIRE data

    Upload a .txt, .fire, .dat, or plain-text .asc file, or paste complete 750-character records.

  2. 2
    Convert locally

    Parse Publication 1220 records and build the matching IRIS XML on this device.

  3. 3
    Review and download

    Check the result against the complete TY2025 IRIS file format, then preview or download the XML.

Need to transmit the returns?

Turn the converted data into a completed IRS filing

An XML file is one part of the IRIS filing workflow. Direct transmission also uses an IRIS A2A TCC, approved access, authentication, submission tracking, and IRS acknowledgments. BoomTax can import the FIRE data, help resolve validation issues, transmit the returns, and provide filing status in one workflow.

Common questions

FIRE to IRIS converter FAQ

Can I convert an IRS FIRE file to IRIS XML online?

Yes. This browser-based FIRE to IRIS converter reads supported TY2025 Publication 1220 files, maps their fixed-width 1099 records to IRIS XML, checks the generated file against the TY2025 IRIS format, and enables a local download.

Does the converter upload my tax data?

No. Parsing, XML generation, and format checking run in your browser. The converter does not send the FIRE file, generated XML, filename, TINs, names, addresses, or amounts to FireToIris.com or BoomTax.

Which FIRE form types are supported?

The TY2025 converter supports original domestic returns for Forms 1099-A, 1099-B, 1099-C, 1099-CAP, 1099-DIV, 1099-G, 1099-INT, 1099-K, 1099-LS, 1099-MISC, 1099-NEC, 1099-OID, 1099-PATR, 1099-Q, 1099-R, 1099-S, 1099-SA, and 1099-SB, plus valid CF/SF coding and reconciled K records for eligible forms.

Is the downloaded XML already filed with the IRS?

No. The download is an IRIS XML file for review and use in a filing workflow. Filing is a separate transmission process with credentials, authentication, acknowledgments, and acceptance checks.

Can I validate IRIS XML that I already have?

Yes. Use BoomTax's free IRS IRIS XML validator to check an existing TY2025 XML file in your browser.
