The Biggest Rewrite of Federal Grant Rules Since 2013: What OMB's Uniform Grants Regulation Means for Every Applicant Before October 1

Most grant news is about a specific program: a deadline, a dollar figure, a set of eligible applicants. This is not that. On May 29, 2026, the Office of Management and Budget published a proposed rule in the Federal Register — "Regulation for Federal Financial Assistance," docket OMB-2026-0034 — that would rewrite the rulebook underneath every federal grant. It is the most sweeping revision to the government-wide grants framework, 2 CFR Part 200 (the "Uniform Guidance"), since it was first issued in 2013. The comment period closed July 13, 2026. OMB has said it intends to publish a final rule effective October 1, 2026, applicable to all new FY2027 awards.

If you apply for federal money — as a university, a nonprofit, a state or local government, a hospital, or a small business — this rewrite is the most important development of the year, and it has almost nothing to do with any single funding opportunity. It changes who decides whether you get funded, how securely you hold an award once you win it, and what you are allowed to spend the money on. Below is what the rule actually does, why it drew nearly half a million comments, and what applicants should be doing right now.

From "guidance" to binding regulation

Start with the structural move, because everything else follows from it. Today, 2 CFR Part 200 is technically guidance — OMB issues it, and each agency adopts it into its own regulations. The proposal reclassifies the framework as a binding regulation that concentrates policymaking authority at OMB rather than at the individual agencies.

That sounds like plumbing. It is not. Binding the framework at the OMB level means future changes can be pushed government-wide in one step, without the agency-by-agency adoption process that historically slowed and softened central directives. Whoever controls OMB controls the terms of every grant, immediately. The rewrite is as much about who holds the pen going forward as about any single provision inside it.

Political appointees in front of every discretionary award

The provision drawing the most alarm is a new pre-issuance review. Under the proposal, senior political appointees (or their designees) must review every discretionary grant before it is issued, to confirm the award "demonstrably advances the President's policy priorities" and aligns with "Gold Standard Science" benchmarks.

Crucially, the rule reduces scientific peer review to "advisory." Under the current system, a panel of subject-matter experts scores proposals on merit, and agencies fund down the ranked list. Under the proposal, that expert ranking no longer obligates an agency to fund anything — a political appointee sits between the peer-review score and the award decision and can decline to fund a top-ranked proposal.

For 80 years, the premise of federal research funding has been that scientists, not political officials, judge scientific merit. This provision inverts that premise for discretionary awards. Supporters frame it as accountability — elected leadership directing taxpayer money toward national priorities. Critics, including free-market economist Alex Tabarrok of George Mason University, call it "a nightmare of petty low-trust review" layered onto a system "already drowning" in administrative burden.

"National interest" termination — with no appeal

The second structural change is on the back end. Today, an agency generally cannot claw back an award mid-stream absent noncompliance or fraud. The proposal lets agencies terminate a discretionary grant, in whole or in part, whenever termination is "in the interest of the federal agency" — specifically, when the award "no longer effectuates program goals, Federal agency priorities, or the national interest."

Three details make this consequential:

• The rule explicitly contemplates changing priorities. It states that termination can rest on circumstances "as they exist at the time of the termination" — meaning a project funded under one set of priorities can be cut when those priorities shift, even if the grantee has done nothing wrong.
• Termination requires only "a brief summary" of reasons. No finding of noncompliance is needed.
• There is no appeal. The proposal provides that agencies "would not be required to provide objection, hearing or appeal rights for discretionary terminations." Appeal rights survive only for noncompliance-based terminations.

A new 90-day suspension authority — discretionary stop-work orders — sits alongside the termination power.

The practical meaning: a multi-year award becomes contingent on the priorities of the moment. Research!America's Russ Paulsen warned that canceling clinical trials midstream would be "unjust to patients...who would then be told...we're going to stop this experiment." For any organization that hires staff, signs leases, or enrolls participants on the strength of a federal award, "national interest" termination reprices the risk of accepting federal money.

What you can no longer spend the money on

The proposal codifies a set of prohibited activities and conditions that apply as terms of the award:

• DEI policies that violate federal anti-discrimination law.
• "Gender ideology" as defined in Executive Order 14168 — "theories or ideologies that deny the biological reality of sex" — including gender-transition care for individuals under 19.
• Disparate-impact liability theories, in any context.
• Collaboration with "covered foreign countries" or entities, absent agency-head approval — a government-wide extension of the "Wolf Amendment" model, paired with E-Verify enrollment for U.S.-based employees and contractors.

It also tightens allowable costs. Under the proposal, publication costs become unallowable unless expressly required by statute or pre-approved; conference attendance requires express approval in the award terms; journal subscriptions become categorically unallowable; advertising and public relations are largely barred; and the definition of unallowable lobbying expands to include voter registration and advocacy to state executive branches. Fixed-amount awards would be eliminated unless a statute authorizes them, pushing grantees toward cost-reimbursement — with its heavier documentation load and per-request payment justifications.

One thing the proposal notably leaves alone: the indirect cost rate negotiation system. OMB stated it made no changes to facilities-and-administrative (F&A) rates, citing FY2026 appropriations language that restricts such changes — while signaling it may revisit the issue later. Given the prior fights over capping indirect rates, that restraint is temporary at best.

Why it drew nearly 497,000 comments

The response was extraordinary. OMB received 496,769 comments in the 45-day window. An analysis by Tech Policy Press of roughly 51,000 posted comments found 94% opposed the proposal and 6% supported it.

The opposition is unusually broad. It includes House and Senate Democrats, but also Senate Appropriations Chair Susan Collins (R-Maine), who warned the rule would "harm small and rural communities, undermine scientific and biomedical research." It includes advocacy groups (Stand Up for Science, Research!America), state and local governments, medical and scientific researchers — and free-market conservatives who object to the added bureaucracy.

Two lines of legal attack are already forming. Stand Up for Science says it is "prepping with our partners for the legal battles." And Arnold & Porter has publicly questioned "whether OMB has the requisite statutory authority to impose binding regulations" at all — a threshold challenge, alongside likely First Amendment viewpoint-discrimination and unconstitutional-conditions arguments aimed at the DEI, gender, and viewpoint-neutrality provisions. Congress has also moved to block implementation through appropriations riders.

None of that guarantees the rule is delayed. Comment volume and litigation threats do not stop an effective date; only a court order or a change of heart at OMB does. Applicants should plan for the rule to take effect October 1 as written, and treat any softening as upside.

What applicants should do now

• Assume FY2027 awards carry the new terms. If your award year begins on or after October 1, 2026, build your budget and workplan around cost-reimbursement mechanics, tighter allowable-cost rules, and E-Verify compliance.
• Stress-test your dependence on a single federal award. "National interest" termination with no appeal means a multi-year grant is no longer a guarantee of multi-year funding. Diversify — foundation, state, and earned revenue — so a mid-stream cancellation is survivable, not existential.
• Scrub proposal language against the prohibited-activities list. Whatever your view of the DEI and gender provisions, they will be enforced as award terms. Program descriptions written for a prior era may now create a compliance exposure.
• Read the National Interest and priority signals literally. With peer review demoted to advisory, explicit alignment between your project and stated administration priorities is no longer a nicety — it is the second gate every discretionary proposal must clear.
• Watch the final rule, not the proposal. OMB can change provisions between proposal and final. The version that governs your award is the one published effective October 1.

We covered the initial proposal as it broke in Granted News. This is the structural shift underneath every program we write about — the NSF SBIR relaunch, the Genesis Mission expansion, and the discretionary grants across every agency. A single program's deadline matters for a season. This rewrite sets the terms of federal funding for years. Understand it before you sign your next award.
