A nonprofit that has spent decades collecting checks from private donors just told a federal court it doesn't trust the IRS to keep a secret anymore — and it has a receipt.
On July 13, 2026, Young America's Foundation (YAF), a 501(c)(3) organization led by former Wisconsin governor Scott Walker, filed suit against the IRS, the Treasury Department, IRS Commissioner Frank Bisignano, and Treasury Secretary Scott Bessent. The lawsuit doesn't ask for a single dollar in damages. It asks for something narrower and, in some ways, more consequential: an order barring the IRS from ever collecting YAF's confidential donor list again.
If your organization files a Form 990 with a Schedule B attached, this case is worth five minutes of your attention — because the legal theory behind it could eventually reach you too.
The Breach That Started It
The lawsuit traces back to Charles Littlejohn, a former IRS contractor who is currently serving a prison sentence for leaking confidential tax return data. Littlejohn's leak became infamous for exposing the tax returns of high-profile billionaires to news organizations, but the fallout wasn't limited to individual taxpayers. YAF says its own confidential filings were compromised in the breach, and it only learned about it in 2024 — years after the exposure occurred.
That timeline matters. An organization can follow every filing rule to the letter and still have no control over what happens to its data once it sits in a federal database. YAF's argument is essentially: if you can't guarantee this information stays confidential, stop requiring us to hand it over in the first place.
What Schedule B Actually Requires
Schedule B — officially the "Schedule of Contributors" — is the attachment to Form 990, 990-EZ, or 990-PF where an organization lists the names, addresses, and contribution amounts of its major donors. The filing threshold is the greater of $5,000, or for certain public charities, 2% of total contributions reported on the return.
Here's the detail that makes YAF's argument land: the IRS doesn't apply this rule evenly across the nonprofit sector. Back in 2020, under final Treasury regulations, the agency exempted 501(c)(4) social welfare organizations and most other exempt categories from disclosing donor names and addresses at all — they still report contribution amounts, just not who gave the money. Section 501(c)(3) public charities and 527 political organizations, however, remain on the hook for full donor identification.
YAF's lawsuit points to news from April 2026 that Treasury and the IRS were exploring an expansion of Form 990 donor-information requirements, rather than a rollback — moving in the opposite direction from the trend the 2020 rule had started.
The Legal Theory: Exacting Scrutiny
YAF isn't inventing a new constitutional argument. It's leaning on a 2021 Supreme Court precedent that already reshaped this exact area of law: Americans for Prosperity Foundation v. Bonta.
In that case, California required charitable organizations to submit unredacted donor lists to the state Attorney General's office alongside their federal filings. In a 6–3 decision, the Supreme Court struck the requirement down, holding that any government demand for wholesale donor disclosure must survive "exacting scrutiny" — meaning the disclosure requirement has to be narrowly tailored to a sufficiently important government interest, not just administratively convenient. The Court found California's blanket rule failed that test, and the ruling ultimately invalidated similar disclosure mandates in New York and New Jersey as well.
YAF's litigation director at the National Taxpayers Union Foundation, which is handling the case, framed the argument bluntly: "We say that the collection of this information by the IRS for every single nonprofit can't meet that level of scrutiny."
The core claim is that if a state can't compel blanket donor disclosure without narrow tailoring, neither can the federal government — and the fact that the IRS already carved out an exemption for 501(c)(4)s in 2020 undercuts any argument that universal disclosure is essential to enforcement. If donor names aren't strictly necessary to police one entire category of tax-exempt organizations, the lawsuit argues, they aren't strictly necessary for another.
Why This Case Reaches Beyond One Nonprofit
Whatever the outcome, three things about this case are worth watching if you run or advise a 501(c)(3):
- The remedy sought is injunctive, not monetary. YAF isn't trying to get paid for the breach — it's trying to change the underlying filing requirement going forward. A win here wouldn't just help YAF; it could reshape what every 501(c)(3) has to disclose on future Schedule B filings.
- The IRS's own inconsistency is now a legal weapon. The 2020 carve-out for 501(c)(4)s, originally framed as a targeted policy choice, is being read back as evidence that the broader rule for 501(c)(3)s was never as essential as claimed.
- Data-breach exposure is becoming a First Amendment argument, not just a cybersecurity failure. Historically, a leak like Littlejohn's would be litigated as a privacy or negligence claim against the government. YAF is instead using it as the factual predicate for a constitutional challenge to the underlying collection requirement — arguing that if the government can't protect the data, it shouldn't be allowed to demand it.
If a court agrees that mass Schedule B collection for 501(c)(3)s fails exacting scrutiny, the ripple effects would touch the compliance calendar of every public charity that currently attaches a donor schedule to its annual return — including the growing number of nonprofits that already treat Schedule B as a routine, low-scrutiny formality rather than something worth a second look.
What Nonprofit Bookkeepers Should Do in the Meantime
Nothing about your current filing obligation has changed yet — Schedule B is still required for 501(c)(3)s under existing regulations, and this case is in its early stages. But it's a good prompt to tighten up how your organization handles donor data internally, regardless of how the litigation resolves:
- Keep a clean, auditable donor ledger that separates public-facing gift acknowledgments from the confidential contributor detail that goes into Schedule B, so you're never guessing what's disclosable and what isn't.
- Reconcile your development/CRM donor records against your accounting records before every 990 filing — mismatches between what your fundraising software shows and what your books show are one of the most common sources of Schedule B errors.
- Document your basis for the $5,000 (or 2%) threshold calculation each year, since that number depends on total contributions reported elsewhere on the return and can shift as your organization grows.
Whether or not the courts ultimately side with YAF, this is a useful reminder that donor and contribution records deserve the same rigor as any other financial statement — accurate, well-documented, and reconciled long before a filing deadline or, in this case, a federal complaint puts them under a spotlight.
