Introduction: What is Publication 5406?
IRS Publication 5406, titled “Overview of Form 1023 E-Filing,” is the official step-by-step walkthrough published by the Internal Revenue Service to help nonprofit organizations navigate the electronic application process for 501(c)(3) tax-exempt status. As verified in the latest IRS forms and publications repository updates for 2026, the active revision of Publication 5406 remains Catalog Number 74171W (originally designated with the April 2020 revision date). The IRS continues to mandate electronic submission through the Pay.gov portal for all applicants seeking recognition under Section 501(c)(3).
Before this publication and the digital transition, organizations filed bulky paper applications consisting of dozens of pages and physical attachments. Publication 5406 acts as an educational slide deck and guide, demystifying the digital filing workflow and helping nonprofit founders understand what documents they need before logging in.
While the publication explains how to complete and electronically submit the form on Pay.gov, it works alongside substantive guides like Publication 557 to ensure your organization meets all legal and operational standards for exemption.

Detailed Breakdown of Main Concepts
To successfully file Form 1023 online, taxpayers must grasp several fundamental concepts outlined in Publication 5406. Understanding these items in advance saves weeks of delay.
1. Pre-Submission Essentials: Legal Formation and EIN
You cannot simply decide to start a charity and immediately fill out Form 1023. The IRS requires your organization to be legally formed under state law first. This means having an approved Articles of Incorporation, Articles of Organization, or a signed Trust Instrument.
Additionally, your organization must obtain a nine-digit Employer Identification Number (EIN) from the IRS. You cannot use a founder’s personal Social Security Number on behalf of the nonprofit.
2. The Pay.gov Platform
All full Form 1023 applications must be submitted via Pay.gov, which is a secure service provided by the U.S. Department of the Treasury. You must register for an individual or business account on Pay.gov before starting your application. If you already have an account used for other federal filings, you can reuse the same login.
3. The Single PDF Attachment Rule
One of the most critical technical rules highlighted in Publication 5406 is how supporting documents are handled. You cannot upload dozens of individual files. Instead, all organizing documents, bylaws, conflict of interest policies, and additional explanatory schedules must be merged into a single PDF document not exceeding the IRS file size limit.
4. Protecting Personal Information
Approved Form 1023 applications are public documents open to citizen inspection. Publication 5406 warns applicants never to include sensitive personal details, such as Social Security numbers, personal bank routing details, or personal identification numbers, anywhere in the application or uploaded attachments.
| Application Stage | Required Action | Key IRS Rule / Guideline |
|---|---|---|
| Stage 1: Pre-Filing | Form legal entity & obtain EIN | Must have filed organizing documents with your state |
| Stage 2: Document Prep | Combine supporting files into 1 PDF | No Social Security numbers; respect PDF file size caps |
| Stage 3: Pay.gov Entry | Complete Form 1023 digital fields | Save progress frequently in your Pay.gov profile |
| Stage 4: Submission & Fee | Pay required IRS user fee | Electronic check or debit/credit card accepted |
Practical Examples or Scenarios
Scenario 1: Starting a Local Animal Rescue
Maria wants to open a rescue shelter for abandoned cats. She files Articles of Incorporation with her state’s Secretary of State and obtains an EIN online from the IRS. Before sitting down at Pay.gov, she reviews Publication 5406.
Following the publication’s checklist, Maria scans her stamped Articles of Incorporation, her newly drafted bylaws, and a projected three-year operational budget into a single PDF file on her laptop. When she logs into Pay.gov, she easily completes each section, uploads her single file, pays the user fee, and receives a digital confirmation without delays.
Scenario 2: The Incomplete Attachment Error
David is creating an educational tutoring foundation. He fills out Form 1023 on Pay.gov but uploads only his state receipt rather than his actual signed Articles of Incorporation containing the required exempt dissolution clause.
Because he did not follow the guidelines explained in Publication 5406, the IRS cannot determine if the charity is properly organized. An IRS agent must contact David, requesting additional documentation, which adds months to his application review.
How This Publication Relates to Specific Forms
Publication 5406 does not exist in isolation. It serves as a companion bridge to several other forms and resources:
- Form 1023 (Application for Recognition of Exemption Under Section 501(c)(3)): The primary comprehensive form that larger charitable organizations must complete. Publication 5406 is specifically written to guide users through its electronic version.
- Form 1023-EZ (Streamlined Application): A simplified form for smaller organizations with projected gross receipts under specific annual limits and modest balance sheets. Publication 5406 helps users identify the difference so they choose the correct option on Pay.gov.
- Form SS-4 (Application for Employer Identification Number): The form used to obtain the EIN required on page one of Form 1023.
- Publication 557 (Tax-Exempt Status for Your Organization): While Publication 5406 explains the technical how-to of e-filing, Publication 557 explains the substantive legal rules for maintaining tax-exempt status.
Common Misunderstandings Clarified
Nonprofit organizers frequently encounter confusion when working through the tax exemption process. Here are three common misconceptions clarified by Publication 5406:
- Misconception: You can mail a paper Form 1023. Reality: The IRS no longer accepts paper Form 1023 applications. The entire process must be completed electronically on Pay.gov.
- Misconception: Publication 5406 grants your exemption. Reality: Publication 5406 is purely an educational orientation tool. Filing the form correctly starts the review process, but it does not guarantee automatic approval.
- Misconception: You can upload files one by one as separate documents. Reality: Pay.gov requires all supplemental attachments to be concatenated into a single PDF document before uploading.
Why This Publication Matters for Taxpayers
Submitting an exempt organization application is often the most critical hurdle a new nonprofit faces. Delays can stall fundraising, cause donors to withhold grants, and delay operations.
By reviewing Publication 5406, organizations avoid basic technical errors that result in rejected submissions. It provides transparency into user fees, file formatting, and IRS communications, allowing organizers to set realistic expectations for their launch timeline.
Frequently Asked Questions
Is Form 1023 still required to be filed electronically?
Yes. The IRS requires all Form 1023 submissions to be handled electronically through the Pay.gov portal. Paper versions of Form 1023 are no longer accepted.
Can I save my application and return to it later on Pay.gov?
Yes. When you click save on the Pay.gov form, your draft is saved directly in your personal Pay.gov account under “My Forms.” You have a defined time window to complete and submit your application before the session expires.
What happens if my supplemental attachment exceeds the size limit?
If your combined PDF is larger than the maximum file size permitted by Pay.gov, you will receive an error upon upload. You must compress the PDF or reduce image resolutions while ensuring the text remains legible.
How do I know the IRS received my Form 1023 submission?
Once you sign the application electronically and complete the fee payment, Pay.gov generates a tracking number and confirmation receipt. You should download and print this confirmation for your nonprofit’s permanent records.
Conclusion
Starting a tax-exempt organization requires both a worthy charitable mission and careful administrative diligence. IRS Publication 5406 provides a practical roadmap through what can otherwise be an intimidating online filing process.
By understanding the pre-filing requirements, organizing your PDF attachments, and navigating Pay.gov correctly, you set your charity up for an efficient, error-free path to 501(c)(3) recognition.
