This bill inserts a new paragraph into Internal Revenue Code section 501(p) to create a specific mechanism for terminating or suspending the tax-exempt status of “terrorist supporting organizations.” It authorizes the Secretary of the Treasury to designate an organization that provided material support or resources to a terrorist organization during the prior three years (above a de minimis amount), triggers the suspension rules already in §501(p), and sets out notice, cure, rescission, appeals, and judicial-review procedures.
The measure matters because it converts national‑security findings about material support into a tax consequence rather than relying solely on criminal or foreign‑policy tools. That widens the IRS’s enforcement role, introduces administrative steps that use classified information, and creates compliance and reputational risks for charities, donors, and grantmakers that operate in conflict zones or with international partners.
At a Glance
What It Does
The bill adds paragraph (8) to IRC §501(p). It defines a “terrorist supporting organization” by a 3‑year retrospective showing of material support (using the §2339B(g)(4) federal definition with two narrow exceptions), allows the Secretary to designate such organizations after a 90‑day notice-and‑opportunity‑to‑cure period, and ties the start and end of the tax‑exemption suspension to that designation and any rescission.
Who It Affects
Domestic and foreign nonprofits that send funds, goods, or other resources internationally; foundations and donors who fund international projects; tax advisers and compliance teams for charitable organizations; and the Treasury and IRS units that will have to investigate, manage classified evidence, and administer designations and appeals.
Why It Matters
The bill uses the tax code as a national‑security enforcement lever, not merely a revenue tool: a designation can suspend tax benefits without a criminal conviction. That creates new administrative responsibilities for the IRS, raises transparency and due‑process questions (especially where classified information is involved), and could chill humanitarian or partner‑based activities in high‑risk areas.

What This Bill Actually Does
The bill amends section 501(p) of the Internal Revenue Code by adding a new paragraph that targets organizations the Secretary determines provided material support or resources, within the previous three years, to entities already described in paragraph (2) of §501(p). It borrows the federal criminal statute’s definition of “material support or resources” (18 U.S.C. §2339B(g)(4)) but expressly excludes two categories: support approved by the Secretary of State with the Attorney General’s concurrence under that criminal statute, and humanitarian aid approved by the Office of Foreign Assets Control.
The bill requires the support to exceed a de minimis amount.
Before making a designation, Treasury must mail a written notice to the organization’s most recent address listed on its IRS filings (Form 990 series or successor). The notice must identify recipient organizations and describe the material support at issue unless disclosure would harm national security or law enforcement; if the Secretary withholds that description, the notice must say so.
The organization then has 90 days to avoid designation by either convincing the Secretary it did not provide the support, taking reasonable steps to recover or return the resources and certifying it will not provide further support, or—if the Secretary withheld a description—filing a complaint in federal district court contesting that withholding.If the organization does not satisfy one of those options within 90 days, Treasury designates it as a terrorist supporting organization and treats it “as described in paragraph (2)” of §501(p), which means the suspension period described elsewhere in §501(p) begins on the designation date and continues until the Secretary rescinds the designation. The bill builds in rescission paths: the Secretary must rescind if the designation was erroneous, if the organization credibly shows it never received notice and then satisfies the cure conditions, or when all suspension periods for the recipient organizations have ended.
The statute also gives organizations two review routes: administrative resolution through the IRS Independent Office of Appeals and judicial review in U.S. district court. Where determinations rely on classified information, courts may receive that material ex parte and in camera.
Finally, the amendment directs Treasury to adopt policies ensuring its employees comply with laws governing classified information and makes the change effective for designations made after enactment and for taxable years ending after enactment.
The Five Things You Need to Know
The bill defines a ‘terrorist supporting organization’ by a 3‑year lookback: any organization that provided material support to a listed terrorist group during the prior three years in excess of a de minimis amount.
It imports the material‑support definition from 18 U.S.C. §2339B(g)(4) but explicitly excludes State‑Department/Attorney‑General‑approved support and OFAC‑approved humanitarian aid.
The Secretary must mail a written notice to the organization’s last IRS filing address and give a 90‑day opportunity to either disprove the finding, return the resources and certify no further support, or sue in federal court if Treasury withheld a description on national‑security grounds.
A certification that resources were returned is invalid if the same organization made such a certification within the prior five years, limiting repeat safe‑harbor claims.
The statute creates parallel review routes: the IRS Independent Office of Appeals may resolve disputes administratively, but district courts have exclusive jurisdiction over certain challenges and may review classified evidence ex parte and in camera.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Adds paragraph (8) establishing the terrorist‑support designations
The bill places the new authority inside §501(p) so the designation mechanism ties directly into the existing suspension framework in that subsection. Practically, that means a designation triggers the suspension structure already in law — the suspension period defined in paragraph (3) of §501(p) starts on the date of designation and runs until the Secretary rescinds the designation. This design choice makes tax consequences automatic after designation instead of requiring separate statutory penalty language.
Definition of 'terrorist supporting organization' and material support rules
This subsection sets the substantive standard: an organization qualifies if it provided material support or resources to a paragraph‑(2) organization during the preceding three years above a de minimis threshold. To reduce ambiguity, the bill references the federal criminal definition in 18 U.S.C. §2339B(g)(4) but carves out two exceptions for support that is approved by the State Department/Attorney General or humanitarian assistance approved by OFAC. The explicit lookback period and reference to a de minimis floor will matter in investigations and compliance reviews.
Designation procedure: notice content and 90‑day cure period
Treasury must mail a written notice to the organization’s address on its most recent Form 990 (or successor). The notice must identify recipient organizations and describe the material support unless disclosure would jeopardize national security or law enforcement; if the Secretary withholds that description, the notice must say so. The organization then has 90 days to (a) demonstrate it did not provide the support, (b) make reasonable efforts to return the resources and certify it will not provide further support, or (c) if the description was withheld, file suit challenging that withholding. The mailing‑and‑90‑day sequence creates a short administrative window to resolve disputes before automatic suspension.
Rescission triggers and certification limits
The Secretary must rescind a designation if the determination was erroneous, if the organization credibly demonstrates it never received notice and then satisfies the cure conditions (subject to a five‑year bar on repeated certifications), or when the suspension periods tied to the recipient organizations end. The five‑year rule prevents serial certifications from being used to evade designations repeatedly and limits the availability of that cure pathway.
Administrative appeals and exclusive judicial review
The bill makes disputes subject to the IRS Independent Office of Appeals under §7803(e) as if the IRS made the designation, but it also gives U.S. district courts exclusive jurisdiction over certain challenges, including complaints about withheld descriptions and final designation decisions. The statute clarifies that a final designation remains reviewable in district court even if the taxpayer did not exhaust the IRS appeals process, and permits courts to review classified materials in camera and ex parte when determinations rest on classified information.
Classified‑information handling and application timing
Treasury must adopt policies ensuring compliance with laws governing classified information handling, reflecting that some notices and determinations may be based on classified intelligence. The amendment applies to designations made after enactment and affects taxable years ending after enactment, which limits retroactive tax consequences to periods that close after the law takes effect.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Treasury and IRS compliance units — gain a statutory, administrable tool to remove tax benefits from organizations linked to terrorist activity without pursuing criminal convictions.
- National security and law‑enforcement agencies — benefit from an additional leverage point to deter or disrupt financial support networks, especially where criminal prosecution is impractical.
- Private donors seeking clearer risk signals — institutional funders and foundations can use public designations as part of their diligence when deciding to continue or cease funding programs tied to high‑risk partners.
Who Bears the Cost
- Humanitarian and international charities — face heightened compliance obligations, reputational risk, and potential suspension of tax benefits based on past partnerships or routing of funds through intermediaries.
- Small nonprofits and community organizations — bear disproportionate legal and administrative costs to respond to notices, certify returns of resources, or defend designations in court.
- The IRS and Treasury — inherit a resource‑intensive task: investigating cross‑border flows, managing classified information in tax proceedings, and adjudicating appeals and litigation.
- Donors and grantmakers — risk losing tax deductions and facing uncertainty about legacy grants made several years earlier, which may chill giving to programs in fragile states.
Key Issues
The Core Tension
The central dilemma is between cutting off financial support to designated terrorist networks as quickly and effectively as possible and preserving due process, transparency, and humanitarian space: the bill prioritizes a swift administrative tax remedy that protects classified intelligence but, in doing so, risks chilling legitimate charitable activity and placing heavy adjudicative and operational burdens on nonprofits and tax authorities.
The bill creates significant implementation questions. First, it relies on the criminal statute’s definition of material support but gives Treasury the civil power to suspend tax benefits; that divergence raises coordination issues across agencies and could lead to inconsistent thresholds between criminal and tax enforcement.
Second, the bill contemplates withholding descriptive evidence from the recipient if national security concerns exist and then requires organizations to challenge that withholding in district court. That design protects sources and methods but reduces transparency, makes administrative cure harder to pursue, and shifts heavy evidentiary burdens into litigation where ex parte, in camera evidence will be decisive.
Third, the ‘de minimis’ qualifier is left undefined here and will be a practical flashpoint: uncertainty about what counts as de minimis support will drive disputes and conservative behavior by charities and grantmakers.
Operationally, Treasury and the IRS will need new investigative capacity, procedures for handling classified information in tax contexts, and guidance for nonprofit due‑diligence practices. The statute also chains rescission to the suspension periods of recipient organizations, creating potential cascading suspensions that could leave an organization’s tax status in limbo for indeterminate periods if related organizations remain suspended.
Finally, the 90‑day cure window is short for complex factual disputes involving cross‑border transfers, intermediaries, and records that may be located abroad, increasing the odds that meritorious defenses will require costly litigation rather than administrative resolution.
