The match number in your budget is a promise. It is not necessarily the number an auditor will accept. Cost share requirements federal grants attach to are governed by 2 CFR 200.306, and that section does something most budget templates ignore: it sets a separate valuation ceiling and a separate documentation standard for every category of contribution. Donated equipment, loaned equipment, donated space, volunteer hours, and unrecovered overhead each get counted a different way. Write them all in at face value and you have built a shortfall you will discover at closeout.

The Match You Volunteer Buys You Almost Nothing at Review

Start with the part of the rule that changes the economics of the whole decision. Section 200.306(a) states that voluntary committed cost sharing “is not expected under Federal research grants,” and that the federal agency “may not use voluntary committed cost sharing as a factor during the merit review of applications or proposals for Federal research grants” unless a statute or agency regulation authorizes it and the notice of funding opportunity specifies how it will be considered. For non-research programs, agencies are “discouraged” from scoring it, and if they do, the NOFO has to say so up front.

The 2024 rewrite of the Uniform Guidance sharpened this. EPA’s own agency webinar on the 2024 revisions lists the change plainly: the section is now titled “Cost Sharing,” with “or matching” removed, and voluntary committed cost sharing may not be used as a merit review factor for federal research grants. The word “matching” survives in conversation, not in the regulation.

Read those two facts together and voluntary match becomes a one-sided trade. It cannot lift your score on most research mechanisms. It can absolutely generate a finding, a proportional reduction of the federal share, or a repayment demand if you fall short. If the funding notice does not require match, the default answer is to leave the field empty and put the resources toward a stronger project design instead. When you are scanning programs in the OpenGrants grant database, the cost share line in the NOFO is the only place that question gets settled — not the program’s reputation, and not what a peer organization did last cycle.

Four Ceilings That Cut Your Match Below What You Wrote

Here is where budgets quietly break. Section 200.306 does not accept contributions at whatever number you assign them. It caps each type, and the caps are not intuitive.

• Donated equipment and supplies. The assessed value may not exceed the property’s fair market value at the time of donation — for equipment, fair market value of equipment of the same age and condition. A ten-year-old analyzer is worth what a ten-year-old analyzer is worth, not what the donor paid.
• Loaned equipment. Value it at fair rental value, not at the value of the asset. This single line is responsible for a large share of overstated match. A partner lending you a $180,000 instrument for eight months is contributing eight months of rent, not $180,000.
• Donated space. Capped at the fair rental value of comparable space, established by an independent appraisal of comparable space in a privately owned building in the same locality. Your own internal square-foot rate is not the benchmark; the local commercial market is.
• Donated land or buildings for construction or long-term use. When the agency authorizes the donation, the value is the lesser of the remaining life recorded in your accounting records or current fair market value — with fair market value permitted above that only where there is sufficient justification and the agency approves.

Build the match column as four separate calculations with four separate ceilings and the total falls, sometimes sharply. Better to find that out in week two of proposal development than in month thirty of performance. Organizations running several federal awards at once should be doing this arithmetic centrally, which is one reason match modeling belongs with the same team that handles budgets and reporting rather than with individual program staff. If you do not have that capacity in house, an experienced budget reviewer from the OpenGrants grant writer network will catch a mis-valued loan or donation faster than an auditor will.

The Match You Already Own and Are Not Counting

The ceilings cut in one direction. Three provisions cut the other way, and applicants routinely leave them on the table.

Unrecovered indirect cost

Section 200.306(c) allows unrecovered indirect costs — the difference between what you charged the award and what you could have charged under your approved rate — to count as cost share, including indirect on the cost-shared amount itself, with the prior approval of the federal agency or pass-through entity. When a program caps indirect recovery below your negotiated rate, that gap is often the single largest match source you have. The catch is real, though: prior approval means written approval, in advance. Assume it and you have assumed away your match.

Third-party volunteer services

Volunteer professional and technical services can count when the service is necessary for the program. The rate has to be consistent with what you pay for similar work; if the skill does not exist in your workforce, use rates for similar work in the labor market where you compete for those services. Allowable, allocable, reasonable fringe may be added to the valuation. A pro bono attorney is valued as an attorney, not at a generic volunteer rate.

Employees furnished by another organization

When a third-party organization supplies one of its employees, 200.306(f) values that at the employee’s regular rate of pay, plus reasonable fringe, plus indirect costs at either the third party’s federally negotiated rate or a rate under 200.414(d). Most applicants count the salary and stop. The fringe and indirect layers are in the regulation and are frequently the difference between meeting a 25% match and missing it. This matters disproportionately for coalition applications and for the partner-heavy models common across nonprofit grant programs.

Seven Tests Every Match Dollar Has to Pass

Valuation is only half the exam. Section 200.306(b) requires the agency or pass-through entity to accept a contribution — cash or third-party in-kind, from you, a subrecipient, or a third party — when it meets all seven conditions: verifiable in your records; not counted as a contribution for any other federal award; necessary and reasonable for the objectives; allowable under Subpart E; not paid by the federal government under another federal award, except where the authorizing statute specifically permits it; provided for in the approved budget when the agency requires that; and conforming to the rest of Part 200.

Two of those seven do most of the damage in practice. The no-double-counting rule means the same staff hour, the same donated space, the same partner contribution cannot be pledged to two awards. Organizations with a growing federal portfolio break this rule by accident, not by intent, because match commitments live in proposals rather than in a shared ledger. And “verifiable in your records” is a documentation standard identical to the one applied to costs you bill: contemporaneous logs, signed timesheets, appraisals, written confirmation from the contributing party. Reconstructing match at closeout is the pattern auditors are trained to look for.

Since fiscal years beginning on or after October 1, 2024, the Single Audit threshold sits at $1,000,000 in federal expenditures, and matching sits inside the compliance requirements auditors test. If your organization is anywhere near that line, the match file is not paperwork you produce on request — it is a system you maintain from the first month of the project period. Teams building toward that scale will find the ground rules across federal grant programs more consistent than they expect; the variation is in the ratio, not in the proof standard.

Why the Proposed Rule Could Shrink Your Match Pool

Now the part almost nobody connects. On May 29, 2026, OMB and dozens of federal agencies published the Regulation for Federal Financial Assistance, a proposed overhaul that would convert the Uniform Guidance into binding regulation with a targeted effective date of October 1, 2026. The Congressional Research Service summary of the proposal walks through the headline changes: regulatory status, termination authority, and agency conforming amendments. A Senate continuing appropriations provision released in early August would bar OMB from finalizing the rule until December 11, 2026, and would suspend any version finalized before enactment — so the calendar is genuinely unsettled.

The proposal does not rewrite 200.306. That is exactly why the risk is easy to miss. Match has to be allowable under Subpart E, and the proposal tightens Subpart E in several places: publication costs would become unallowable absent statutory requirement or case-by-case agency approval, conference attendance costs allowable only when expressly approved in the award terms, advertising and public relations costs presumptively unallowable, and fundraising and investment management costs subject to prior written approval. Every one of those is a cost some organization currently books as in-kind or cash match on an outreach-heavy or dissemination-heavy project.

If a cost stops being allowable, it stops being countable as match, whether or not the match section itself changed a word. Applicants with multi-year projects crossing the effective date should be pressure-testing the match plan against the proposed cost principles now, not after a final rule lands. That is a different exercise from tracking the termination provisions everyone is watching, and it applies as much to small business grant programs with hard match requirements as it does to research institutions.

Frequently Asked Questions

Does every federal grant require cost share?

No. Match applies only when the notice of funding opportunity or the authorizing statute requires it. There is no government-wide default ratio in 2 CFR 200.306. Most standard research project grants at NIH and NSF carry no match requirement; training, infrastructure, and center awards more often do. Read the specific NOFO rather than assuming an agency-wide policy, and if the cost share language is ambiguous, ask the program officer in writing before the deadline.

Can I count another federal grant as my match?

Generally no. Section 200.306(b)(5) bars counting funds paid by the federal government under another federal award, with a narrow exception where the program’s authorizing statute specifically permits federal funds to be applied to another program’s cost share. That exception exists in a handful of programs and is stated in statute, not inferred. The related rule at (b)(2) also blocks counting the same contribution toward two different federal awards.

What happens if I miss my committed match?

The agency can reduce the federal share proportionally, require you to cover the shortfall from other non-federal sources, or record it as a compliance finding. Knowing misstatement in a funding request can raise False Claims Act exposure. The practical response is to monitor match monthly against the committed amount and contact the grants management specialist as soon as a gap appears — a documented budget revision request beats a surprise at closeout.

Does unrecovered indirect cost really count?

Yes, under 200.306(c), including indirect on the cost-shared portion — but only with prior approval from the federal agency or pass-through entity. Get the approval in writing at the budget stage. Many applicants discover the provision at closeout, when prior approval is no longer available and the match is already short.

Bottom Line

Treat the match column as five separate valuation problems rather than one number. Price donated equipment at fair market value at donation, loaned equipment at fair rental value, space at comparable local rent, and third-party staff at pay plus fringe plus indirect — then check whether unrecovered indirect can be added with written agency approval. Run each line through the seven tests in 200.306(b), and attach the proof to the line at the moment it happens.

The specific move to make this quarter: if you have an active or pending award whose match plan leans on outreach, publication, conference, or promotional costs, re-price those lines against OMB’s proposed Subpart E changes before the effective-date fight resolves. Cost share requirements federal grants impose do not have to move for your match to fail — the allowability rules underneath them are enough. If you want a second set of eyes on a match plan before it becomes a binding commitment, the team at OpenGrants grant writing services reviews budgets and cost share structures alongside the narrative, which is where most of these errors are still cheap to fix.
