IRS Publication 5588 – In the fight against terrorism, the U.S. government employs various tools to disrupt financing networks, including those masquerading as charitable organizations. IRS Publication 5588, also known as Exempt Organizations Technical Guide TG 45, provides detailed guidance on the suspension of tax-exempt status for terrorist organizations under Internal Revenue Code (IRC) Section 501(p). This article explores the key aspects of this publication, its historical context, procedures, and implications for nonprofits and donors. Whether you’re a tax professional, nonprofit leader, or concerned citizen, understanding IRC 501(p) is crucial for navigating tax-exempt regulations in a post-9/11 world.
Released in its latest revision in February 2024, Publication 5588 remains a cornerstone resource for IRS agents, exempt organizations, and the public. As of early 2026, no significant updates have altered its core content, making it highly relevant today.
Background and History of IRC 501(p)
The enactment of IRC 501(p) stemmed from the aftermath of the September 11, 2001, terrorist attacks, which highlighted how charities and nonprofits could be exploited for terrorist financing. Prior to this section, revoking an organization’s tax-exempt status required a lengthy IRS process involving examinations, proposed revocation letters, administrative appeals, and potential judicial challenges under IRC Section 7428.
Introduced as part of the Military Family Tax Relief Act of 2003, IRC 501(p) allows for the automatic suspension of tax-exempt status upon a federal designation of an organization as terrorist-related. This measure supports broader federal efforts under laws like the Immigration and Nationality Act, the International Emergency Economic Powers Act, and the United Nations Participation Act of 1945. The goal is to swiftly cut off tax benefits that could inadvertently fund terrorism, without the delays of traditional revocation procedures.
Key terms defined in the guide include:
- Terrorist Organization: An entity designated or identified as supporting or engaging in terrorist activity under IRC 501(p)(2).
- Terrorism: The unlawful use of force and violence to intimidate or coerce governments or civilians for political or social objectives, as per 28 CFR 0.85(l).
Key Provisions of Suspension Under IRC 501(p)
Publication 5588 outlines the core provisions for suspending tax-exempt status, emphasizing that suspension is automatic and triggered by federal authorities, not the IRS itself.
Federal Authorities for Designation
Organizations can be designated as terrorist entities under:
- Sections 212(a)(3)(B)(vi)(II) or 219 of the Immigration and Nationality Act.
- Executive orders pursuant to the International Emergency Economic Powers Act or the United Nations Participation Act of 1945.
- Other federal laws referencing terrorism definitions.
These designations are not exclusive; an organization might fall under multiple categories.
Period of Suspension
Suspension begins on the later of the first publication date of the designation or November 11, 2003 (the enactment date). It ends only when all designations are rescinded. The IRS publishes notices of suspensions but does not initiate them—federal agencies like the Treasury’s Office of Foreign Assets Control (OFAC) or the State Department handle the initial announcements.
Effects and Implications of Suspension
Once suspended, an organization faces severe restrictions:
- Loss of tax exemption under IRC 501(a).
- Ineligibility to apply for new tax-exempt recognition.
- No tax deductions for contributions under sections like 170, 545(b)(2), 642(c), 2055, 2106(a)(2), and 2522.
Importantly, no administrative or judicial challenges are allowed against the suspension, designation, or denial of deductions, overriding provisions like IRC 7428. This applies to both U.S. and foreign organizations, underscoring the global reach of U.S. anti-terrorism tax policies.
For donors, this means contributions to suspended organizations are nondeductible, potentially leading to tax adjustments if claimed erroneously. The IRS updates its listings of tax-exempt organizations to reflect these changes.
Current List of Suspended Organizations
As of December 2025, nine organizations have their tax-exempt status suspended under IRC 501(p). These include:
| Organization Name | Location |
|---|---|
| Al Haramain Islamic Foundation, Inc. | Ashland, Oregon |
| Benevolence International Foundation, Inc. | Palos Hills, Illinois |
| Global Relief Foundation, Inc. | Bridgeview, Illinois |
| Goodwill Charitable Organization Inc. (f/k/a Al-Shahid Social Association and f/k/a Educational Development Association) | Dearborn, Michigan |
| Holy Land Foundation for Relief and Development | Richardson, Texas |
| Islamic African Relief Agency – USA (a/k/a Islamic American Relief Agency – USA) | Columbia, Missouri |
| Rabbi Meir Kahane Memorial Fund | Cedarhurst, New York |
| Tamil Foundation, Inc. | Cumberland, MD |
| Tamils Rehabilitation Organization Inc. | Cumberland, Maryland |
This list is maintained on the IRS website and should be checked regularly for updates.
Suspension vs. Revocation: Key Differences
Suspension under IRC 501(p) differs from traditional revocation. While revocation involves IRS-initiated examinations and appeals, suspension is automatic and non-challengeable. If an organization is under IRS examination when suspended, agents must cease actions, notify managers, and follow specific Internal Revenue Manual (IRM) procedures like IRM 4.70.14.4.10.
Tax Remedies for Erroneous Designations
In cases of erroneous designations, IRC 501(p) provides a tax remedy. If the designation causes an overpayment of income tax, the IRS issues a credit or refund with interest. Claims must be filed within one year of the final determination, even if barred by other laws like res judicata.
Other Considerations: Applications and Examinations
Publication 5588 also addresses broader terrorism-related issues:
- Exemption Applications: Organizations with foreign grants or activities must detail anti-terrorism procedures. Higher risks apply in war-torn areas, requiring OFAC licenses for operations in state sponsors of terrorism.
- Examination Techniques: IRS auditors check against OFAC’s Specially Designated Nationals (SDN) List. If concerns arise, examinations are suspended, and Form 14503 is submitted to the Anti-Terrorism Coordinator.
- Guidance on Foreign Grants: References revenue rulings like 63-252 and 66-79, recommending written agreements, feedback reports, and verification methods.
Additional efforts involve the FBI-led Terrorist Screening Center and OFAC regulations under executive orders like E.O. 13224.
