Introduction – What is Publication 5731?
IRS Publication 5731, titled “Start e-filing Forms 1099 with the Information Returns Intake System,” is the official quick-start guide created by the Internal Revenue Service to help taxpayers navigate electronic information return reporting. It introduces small business owners, sole proprietors, and tax professionals to IRIS, the IRS’s dedicated, no-cost online platform designed specifically for preparing and submitting Form 1099 series documents.
As the IRS accelerated the transition away from paper filings under mandatory digital reporting regulations, continuous guidance updates were issued throughout 2026. Official IRS updates and companion publications, including the release of updated IRIS Portal specifications through September and October 2026 alongside multilingual editions of Publication 5731-B published through May 2026, ensure filers have modern instructions for fulfilling their reporting requirements. Together, these releases give taxpayers a secure, direct channel to submit required filings without purchasing expensive commercial software.
At its heart, Publication 5731 demystifies electronic filing for those who previously mailed paper forms. It explains how to access the portal, manage payee data, correct errors immediately, and download completed forms for independent contractors or payees.
Who Should Read This Publication
Publication 5731 is intended for anyone responsible for issuing information returns at the end of the tax year. Whether you run a single-member LLC, operate a non-profit, or hire occasional freelancers, this guide is built for you.
You should review this publication if you belong to any of the following groups:
- Small Business Owners and Sole Proprietors: Anyone who pays non-employee compensation of $600 or more to independent contractors during the calendar year.
- Landlords and Property Managers: Individuals who pay repair professionals, landscapers, or cleaners in the ordinary course of their rental business.

Key Topics Covered
Publication 5731 provides a high-level roadmap to modern electronic filing. The publication focuses on several central areas to help businesses transition from paper to paperless processing smoothly.
The core subjects outlined in the publication include:
- The core benefits of the Information Returns Intake System (IRIS) Taxpayer Portal.
- The step-by-step enrollment process, including identity verification and Transmitter Control Code (TCC) setup.
- Methods for creating, editing, uploading, and submitting various 1099 forms.
- Built-in error detection tools that validate taxpayer identification numbers and catch mathematical mistakes before submission.
- Procedures for issuing digital or printed copies to payees and managing annual filing archives.
Detailed Breakdown of Main Concepts
1. What is the Information Returns Intake System (IRIS)?
IRIS is a secure web-based portal developed and maintained directly by the IRS. Historically, small businesses filing fewer than a few dozen forms either mailed paper copies or paid private software vendors. IRIS eliminates that cost barrier by providing a free, government-backed submission portal available year-round.
2. The Lowered Electronic Filing Threshold
Under modernized IRS rules, filers who submit 10 or more information returns in aggregate across an entire calendar year are legally required to file electronically. This threshold combines multiple form types, including Forms W-2, 1099-NEC, 1099-MISC, and 1099-INT. Publication 5731 shows small entities how to satisfy this mandatory electronic filing rule without buying expensive accounting add-ons.
3. Two Methods of Entry: Manual vs. Bulk Upload
The publication explains that the IRIS Taxpayer Portal accommodates both micro-businesses and growing enterprises. You can manually enter information for one payee at a time through a simple online form, or you can upload a comma-separated values (CSV) spreadsheet containing up to 100 returns simultaneously.
4. Automatic Validation and Receipt
A major advantage highlighted in Publication 5731 is electronic acknowledgement. When submitting paper forms, filers often wait months to learn if their forms were received or rejected. IRIS validates formatting instantly, flags missing information before submission, and delivers an official status receipt within 48 hours.
Practical Examples or Scenarios
Scenario 1: The Independent Marketing Consultant
Sarah operates a boutique marketing consultancy as a sole proprietor. Over the course of the year, she paid three freelance graphic designers $2,500 each, two copywriters $1,800 each, and a web developer $4,000. Under prior procedures, Sarah purchased paper forms at an office supply store and mailed them with Form 1096. Following Publication 5731, Sarah logs into IRIS, keys in her six contractors’ details directly, receives electronic confirmation within two days, and downloads completed PDF copies to email to her contractors.
Scenario 2: The Residential Rental Property Owner
Marcus owns two residential duplexes. During the year, he paid an independent plumber $1,200, an electrician $850, and a handyman $2,100. Because Marcus needs to report these payments on Form 1099-NEC, he consults Publication 5731. Using the portal, Marcus completes all three submissions within 15 minutes, avoiding postage costs and paper filing delays entirely.
Scenario 3: A Small Business Navigating the 10-Return Rule
Apex Catering employs 6 workers who receive Form W-2, and hires 5 independent delivery drivers who receive Form 1099-NEC. Because Apex files 11 returns in total, the business meets the mandatory e-filing rule. By applying the guidelines in Publication 5731, Apex uses IRIS for its 1099 forms to maintain full compliance and avoid non-filing penalties.
How This Publication Relates to Specific Forms
Publication 5731 directly interfaces with several core IRS tax forms and applications. Understanding which forms can be managed through the portal helps filers streamline their tax workflow.
| Form Number | Form Name | Role in the IRIS System |
|---|---|---|
| Form 1099-NEC | Nonemployee Compensation | Used to report fees, commissions, or other compensation paid to non-employees totaling $600 or more. |
| Form 1099-MISC | Miscellaneous Information | Used to report rents, prizes, legal settlements, and other miscellaneous business disbursements. |
| Form 1099-K | Payment Card and Third Party Network Transactions | Used by payment settlement entities to report commercial transactions, as referenced in companion guide 5731-B. |
| Form 1099-INT | Interest Income | Used to report taxable interest payments of $10 or more paid during the tax year. |
| Form 1096 | Annual Summary and Transmittal of U.S. Information Returns | Not required when using IRIS. Form 1096 is strictly used for physical paper transmittals. |
| IRIS TCC Application | Transmitter Control Code Online Application | The initial credentialing form required to authorize your business to transmit data through the IRIS portal. |
Common Misunderstandings Clarified
Misunderstanding 1: “IRIS charges a service or transmission fee.”
Many business owners assume that filing electronic tax forms involves subscription software fees. The IRIS system described in Publication 5731 is completely free to use. There are no fees per form, transmission surcharges, or hidden maintenance costs.
Misunderstanding 2: “I still have to mail Form 1096 to the IRS after e-filing.”
Form 1096 is only a paper transmittal document. When you submit your 1099 returns electronically through IRIS, the system tallies and transmits the data automatically. Submitting Form 1096 for electronically filed forms is unnecessary and can cause duplicate processing records.
Misunderstanding 3: “Electronic filing rules only apply to large corporations.”
The 10-return aggregated threshold applies to all entities, including single-member LLCs, small partnerships, and sole proprietors. If your combined count of W-2s and 1099s reaches 10, paper filing is prohibited unless you receive a specific IRS waiver.
Misunderstanding 4: “I can set up an IRIS account on the exact day my forms are due.”
Applying for an IRIS Transmitter Control Code (TCC) requires identity verification and IRS processing, which can take several business days or up to two weeks during peak periods. Filers must apply for credentials well before the January 31 reporting deadline.
Why This Publication Matters for Taxpayers
Publication 5731 represents an important tool for small business compliance. Prior to the introduction of IRIS, small filers often felt trapped between tedious paper filing and costly commercial software suites. By offering a straightforward guide to an official IRS platform, this publication saves small business owners real time and operational expenses.
Filing through IRIS also drastically reduces IRS penalty exposure. Automatic error checks catch invalid Taxpayer Identification Numbers (TINs) and formatting discrepancies before submission. Because confirmations arrive within 48 hours, filers gain clear proof of timely filing, eliminating disputes over postmarks or lost mail.
Frequently Asked Questions
Can I file previous-year 1099 forms through IRIS?
Yes. The IRIS Taxpayer Portal allows filers to submit both current tax year forms and prior-year returns. It also maintains an accessible historical archive of your submitted filings.
How do I give my contractors their copy of Form 1099?
Once your submission is accepted in IRIS, you can download pre-formatted, printable PDF copies of Copy B directly from the portal. You can then print and mail these to your payees or distribute them electronically with their prior consent.
What should I do if I discover a mistake after submitting?
IRIS allows users to file electronic corrections directly through the platform for returns originally filed within the system. You can update dollar amounts or addresses without filing manual paper correction sheets.

No. The IRIS Taxpayer Portal is entirely browser-based. All you need is an internet connection, a modern web browser, and an active IRS Online Account verified through ID.me.
Does IRIS replace the older FIRE system?
IRIS operates alongside the IRS Filing Information Returns Electronically (FIRE) system. While FIRE requires specialized ASCII formatting scripts, IRIS provides a taxpayer-friendly portal with visual form entry, making it far simpler for small filers.
