IRS Group Exemption Letter Rules: What Nonprofits Need to Know Under IRS Publication 557

The IRS group exemption letter rules are changing, and nonprofit organizations with chapters, affiliates or local units should take notice. Updated guidance summarized in IRS Publication 557 explains how the Internal Revenue Service is restarting and modernizing the group exemption letter program.

For many organizations, the IRS Publication 557 group exemption guidance governs how tax-exempt status is obtained and maintained across a network of related entities. With the restart of the program, central organizations will face clearer and more formal group exemption letter requirements, particularly around oversight, eligibility and ongoing compliance.

Restart of the Group Exemption Program

The IRS has issued Revenue Procedure 2026-8, which replaces the prior guidance under Revenue Procedure 80-27 and officially restarts the group exemption program as of Jan. 20, 2026. This marks a significant change to the IRS group exemption letter rules after years of limited processing.

As part of this update, the IRS revised Form 8940, which is now the required application for requesting a group exemption letter. All applications must be filed electronically through Pay.gov and include the applicable user fee. These updates reflect a more structured approach to administering and monitoring group exemptions.

Understanding the IRS Group Exemption Letter Rules

A group exemption letter allows a central organization (such as a national association or parent nonprofit) to obtain recognition of tax-exempt status for itself and its eligible subordinate organizations through one IRS determination.

Under the IRS group exemption letter rules:

• Subordinate organizations generally don’t file their own Form 1023 or Form 1024 to apply for tax-exempt recognition.
• Subordinate organizations typically file their own annual Form 990 returns.
• The central organization is responsible for confirming that each subordinate meets eligibility standards and continues to comply with applicable requirements.

For nonprofits operating through chapters or affiliates, a group exemption letter can reduce duplicative filings while promoting consistency across the organization.

Group Exemption Letter Requirements for Eligibility and Structure

The updated guidance outlines clearer group exemption letter requirements that a central organization must meet.

• It must have at least five subordinate organizations at the time of application. (To maintain the group exemption letter, the central organization must generally retain at least one subordinate.) Certain transition relief may apply for organizations that already hold group exemption letters.
• It may generally hold only one group exemption letter. Organizations with multiple letters issued in prior years may rely on transition relief but should expect eventual consolidation.
• All subordinate organizations must fall under the same 501(c) paragraph, such as all being 501(c)(3) organizations or all being 501(c)(4) organizations. Subordinates don’t need to match the central organization’s paragraph, but consistency among subordinates is required.

These structural group exemption letter requirements make it important for organizations to review existing affiliate arrangements before applying or during the transition period.

Affiliation, Oversight and Control Under IRS Group Exemption Letter Rules

A major focus of the updated IRS group exemption letter rules is the relationship between the central organization and its subordinates. The IRS expects the central organization to show both affiliation and ongoing oversight.

Each subordinate must be a legitimate chapter or unit of the central organization and must be under the central organization’s general supervision or control.

General supervision includes annual responsibilities collecting and retaining information about subordinate finances, activities and filing compliance, often through review of the subordinate’s Form 990. Central organizations must also educate subordinates in writing about tax-exempt requirements and filing obligations, including sharing links to IRS resources.

Control may be demonstrated through:

• Authority to appoint or remove officers or directors
• Overlapping leadership between the central organization and subordinates
• Written agreements granting governance or operational authority

Documenting these relationships is essential for meeting requirements, especially for organizations that historically allowed affiliates significant autonomy.

Organizations Excluded From Group Exemption Letters

The IRS group exemption letter rules exclude the following types of organizations:

• Foreign subordinate organizations
• 501(c)(29) qualified nonprofit health insurance issuers
• Automatically revoked organizations until reinstated

For 501(c)(3) group exemptions, most private foundations and Type III supporting organizations are generally excluded.

These limitations mean some nonprofit networks may need a mixed approach, with certain affiliates applying for recognition independently.

Application and Ongoing Compliance Requirements

New applications for group exemption letters must be submitted electronically on Form 8940 through Pay.gov. The application requires detailed information, including subordinate listings, activity descriptions, and representations related to oversight and eligibility.

After approval, most central organizations must file annual Supplemental Group Ruling Information (SGRI). The SGRI filing is typically due 30 to 90 days before the end of the central organization’s tax year and updates the IRS on subordinate changes and compliance status.

Failure to meet these ongoing group exemption letter requirements can put the entire group exemption at risk. (Churches, conventions of churches and associations of churches may file SGRI but are not required to do so.)

Key Dates and Transition Considerations

The 27-month rule continues to determine effective dates for newly added subordinates.

Organizations with existing group exemption letters have a transition period from Jan. 20, 2026 through Jan. 22, 2027 to comply with new IRS group exemption letter rules, including:

• The one-letter limitation
• Minimum subordinate thresholds
• Oversight and affiliation standards
• Same-paragraph consistency for subordinates

This transition window allows time for planning, but organizations should begin reviewing their structures well in advance of the deadline.

Practical Takeaways for Nonprofit Leaders

Group exemption letters remain a useful tool, but the IRS group exemption letter rules now require more clarity, documentation, and ongoing involvement from central organizations.

The updated IRS Publication 557 group exemption guidance reinforces the need for stronger governance and documentation across nonprofit networks. Central organizations may need to formalize oversight processes, revise written agreements or reorganize subordinate lists to comply with current group exemption letter requirements.

Finance teams, executives and boards should understand how these rules affect governance, compliance risk, and long-term growth plans, especially for organizations expanding through chapters or affiliates.
