The Biggest Rewrite of Federal Grant Rules Since 2013 Takes Effect October 1 — Here's What Every Applicant Needs to Understand Before They Apply

Every federal grant in the United States — more than $1 trillion a year in research funding, formula money, cooperative agreements, and project awards — runs on a single rulebook: Title 2 of the Code of Federal Regulations, Part 200, universally known as the Uniform Guidance. It governs how you budget, what costs are allowable, how you get audited, and under what circumstances an agency can take the money back. Most applicants never read it. That is about to become a costly habit.

On May 29, 2026, the Office of Management and Budget, joined by roughly 40 grantmaking agencies, published a notice of proposed rulemaking to amend 2 CFR Part 200 — the most sweeping rewrite of the government-wide grants framework since the Uniform Guidance was first consolidated in 2013. The comment period closed in mid-July after drawing an extraordinary response — nearly half a million comments by some counts — and OMB intends to finalize the rule and put it into effect on October 1, 2026, the first day of fiscal year 2027. It would apply to new awards and to new incremental funding actions on existing awards. If you plan to submit a federal proposal this fall, you are applying into the new regime whether you have read it or not.

This is the definitive breakdown of what changes, who is most exposed, and how to adapt your proposals. For the news summary, see Granted News.

Change one: political appointees now sit above peer review

The single most consequential provision is a new pre-issuance review requirement. Under the proposed revision to 2 CFR 200.205, a senior political appointee at each agency must review notices of funding opportunity (NOFOs) before they publish, and must review discretionary awards before they issue, to confirm each is "consistent with applicable law, Federal agency priorities, and the national interest."

Read carefully, this subordinates the scientific and technical peer-review process to political oversight. For decades, the model at agencies like NIH and NSF has been that career program officers and panels of outside experts score proposals on merit, and those scores substantially drive funding decisions. The new provision inserts a political appointee with the authority to override a favorable peer-review recommendation — and critics note the rule does not require the appointee to state a cause for doing so.

The early effects are already visible in the data. In congressional testimony this summer, lawmakers cited that NIH made roughly 34% fewer new awards in 2026 than its historical norm, attributing much of the drop to new layers of political review slowing the pipeline. Whatever one's view of the policy, the operational takeaway for applicants is concrete: the timeline from favorable review to actual award is lengthening, and the set of fundable topics is narrowing toward stated agency priorities.

Change two: near-unappealable termination for "national interest"

The second major change rewrites 2 CFR 200.340, the termination provision. Under current rules, agencies can terminate for cause — noncompliance, failure to achieve goals — with defined procedural protections. The proposed rule adds a broad new discretionary ground: an agency may terminate an award at any time if it determines the award "no longer effectuates program goals, Federal agency priorities, or the national interest."

Crucially, the rule signals that agencies need not provide a hearing or appeal rights for these discretionary "national interest" terminations. That is a significant reduction in the procedural protections recipients have relied on. In practical terms, a multi-year award is no longer a settled commitment; it is a commitment that survives at the continuing discretion of the funding agency and, through the pre-review structure, its political leadership.

This reshapes how prudent organizations should plan. Building a program, hiring staff, or committing matching funds against a federal award now carries a tail risk that did not meaningfully exist before. Diversifying funding sources — layering foundation, state, and earned revenue against federal dollars — moves from good practice to risk management.

Change three: the foreign-collaboration prohibition

A new provision, proposed at 2 CFR 200.220, prohibits using federal funds to support "bilateral or multilateral collaborations, programs or activities with covered foreign countries or covered foreign entities," except where specifically authorized by law. "Covered" tracks the designated foreign-adversary framework used elsewhere in federal law.

For universities, research institutes, and any organization with international partners, subawardees, or foreign national personnel, this demands an immediate audit. A collaboration that was routine on a 2025 award — a data-sharing arrangement, a foreign subaward, a co-PI at an overseas institution — may be prohibited on a 2027 award. The compliance burden of demonstrating that your project does not run afoul of the provision falls on you, and the termination authority above gives the agency a fast lever if it decides you have.

Change four: restricted activities and new mandates

The rule also codifies a set of policy restrictions and administrative mandates that touch the substance of what grants can fund:

• Restricted activities. Federal funds could not support diversity, equity, and inclusion programming, "gender ideology," or related activities, and recipients would be expected to avoid racial preferences. Language that was standard in the "broader impacts" or community-engagement sections of proposals a year ago is now a liability. Every narrative should be reviewed against the new prohibitions before submission.
• E-Verify mandate. Recipients would be required to enroll in and use the Department of Homeland Security's E-Verify system for employees and contractors working on federal awards — a new administrative lift for organizations that have not previously participated.
• Lower-indirect-cost preference. Notably, OMB did not cut negotiated indirect cost rates outright; it said FY2026 appropriations language prohibited doing so. But the rule expresses a preference for awardees with lower rates "all else being equal," a soft signal that cost structure now factors into competitiveness.

What this means when you actually write a proposal

The strategic response is not panic; it is precision. Four concrete adjustments:

1. Align explicitly with stated agency priorities. With a political appointee reviewing every NOFO and discretionary award against "agency priorities and the national interest," proposals that map cleanly onto published strategic plans and administration priorities will clear review faster. Read the agency's current priority statements and mirror their language.

2. Scrub the narrative for restricted-activity exposure. Terms that were assets in the prior era can now trigger a hold or a rejection. This is not about abandoning your mission; it is about describing your work in terms the new rule does not flag.

3. Audit every foreign touchpoint. Map your subawardees, collaborators, personnel, and data flows. Where a covered-foreign-entity connection exists, either remove it from the federal scope of work or document the specific legal authorization that permits it.

4. Stress-test your budget against termination risk. Assume a "national interest" termination is possible mid-stream. Structure milestones, avoid front-loading unrecoverable commitments, and pair federal dollars with non-federal sources wherever the program allows.

The bottom line

The Uniform Guidance rewrite is not a technical cleanup; it is a change in the character of the federal grant relationship. Merit review is now filtered through political priorities, awards are terminable with far less recourse, and the compliance perimeter has expanded to cover foreign ties and program content that were previously unremarkable. The organizations that thrive after October 1 will be the ones that treat the rulebook as strategy — reading the new 2 CFR 200 before they write, not after they lose an award to it. If you are preparing a fall submission, the time to adapt is now, while the rule is being finalized and the first NOFOs under it are being drafted.
