Effort Reporting and Payroll Certification for Federally Funded Research

Effort reporting is the internal-control process an institution uses to demonstrate that salary and wage charges to a federal award are accurate, allowable, and consistent with the work actually performed. Payroll certification is the specific act — usually a signed or electronically-attested statement from the employee, the PI, or a knowledgeable supervisor — that turns an estimate into a record an auditor can rely on. Both exist to answer one question: does the percentage of salary charged to (or cost-shared against) a federal award match the percentage of the person’s time that actually went to that project?

This guide covers the current federal standard, not the retired one many university policy pages still describe, and walks through the calculations research administrators are actually asked to do: converting a percentage of effort into person-months, reconciling committed effort against actual effort, applying the NIH salary cap to a capped individual’s certification, and handling cost-shared and voluntary committed effort correctly.

The current standard: 2 CFR 200.430, not the old “effort reporting system”

Before the 2014 Uniform Guidance, institutions of higher education operated under OMB Circular A-21, which specified named, formal effort-reporting systems — Plan Confirmation and After-the-Fact Activity Records among them — built around periodic signed certification as the compliance mechanism itself. 2 CFR 200 replaced that mandated-form approach. The operative text now is 2 CFR 200.430(g), which requires:

• A system of internal control that provides reasonable assurance that salary and wage charges to federal awards are accurate, allowable, and properly allocated;
• Charges based on records that reflect an employee’s total compensated activity, not just the activity charged to federal awards, and not exceeding 100 percent of that activity;
• Records that reasonably reflect total activity for which the employee is compensated, prepared in a manner consistent with the institution’s own established practices;
• Budget estimates (i.e., proposing effort as a percentage before the fact) as an acceptable basis for charging salaries, provided the estimation process produces reasonable approximations of the activity actually performed, significant changes in work distribution are identified and adjusted promptly, and the institution’s internal-control system includes a periodic after-the-fact review with adjustment to actual costs where estimates were materially wrong.

What this means in practice: a specific named form, a specific signature workflow, and a specific certification frequency are no longer federally mandated. 200.430(g) is an outcome-based internal-control standard — it describes what the system has to achieve (accurate, allowable, properly allocated charges, supportable after the fact) without prescribing the mechanism. 200.430(g)(8) explicitly preserves a federal awarding agency’s authority to require personnel activity reports or specific certifications from an individual recipient institution if that institution’s own controls fall short — so an agency-imposed PAR requirement is still possible, but it is the exception being invoked against a specific recipient, not the default rule for everyone.

Most research institutions still run something that looks like effort certification — a periodic, signed attestation tied to payroll distribution — because it is a well-understood, auditable way to satisfy the internal-control standard, and auditors are comfortable evaluating it. But “effort certification” as a named practice is now a compliance method institutions choose, not a citation an auditor can point to as the rule itself. If your institution’s policy still cites “OMB Circular A-21 Exhibit C” or describes Plan Confirmation as a federal mandate, that description predates the 2014 change and should be corrected. See Effort Reporting Methodologies for a full comparison of the three legacy systems many institutions still run internally, and the Effort Certification and Time and Effort Reporting dictionary entries for the precise definitional distinction between the umbrella concept and the after-the-fact attestation subset.

Institutional base salary: the denominator for every effort calculation

Every effort percentage is a fraction of Institutional Base Salary (IBS) — the annual compensation an institution pays an individual for their appointment, covering the entirety of their professional obligation, whether time is spent on research, teaching, patient care, administration, or other institutionally-assigned activity. IBS is the institution’s own determination; there is no federal formula for calculating it. It excludes income an individual is permitted to earn outside their institutional duties (outside consulting, honoraria, board fees) and excludes discretionary bonuses or incentive pay that isn’t a fixed part of the base appointment. An institution may not increase someone’s base salary as a device for replacing institutional salary dollars with grant funds.

Two numbers get confused constantly and shouldn’t be: IBS is the institution’s own figure, uncapped. A salary cap (like NIH’s) is a separate, externally-imposed ceiling on the rate at which a specific federal funding source will reimburse against IBS. The cap only becomes relevant once IBS exceeds it — see the worked example below.

Converting effort to person-months

NIH and most federal sponsors express committed and reported effort in person-months rather than a bare percentage, because person-months make the appointment type explicit. The formula:

Person-months = percent effort × number of months in the appointment type × FTE fraction (if less than full-time)

Three appointment-type conventions apply, and the “number of months” term above depends on which one describes the individual’s appointment:

• CY (Calendar Year) — a full 12-month appointment; used for staff and faculty on 12-month/fiscal-year contracts.
• AY (Academic Year) — an institution-defined academic term, commonly 9 months, for faculty on 9-month appointments.
• SM (Summer Months) — the remaining institution-defined summer term for a 9-month faculty member, commonly 2-3 months, used when that person is paid separately for summer research effort outside their academic-year appointment.

Person-months conversion table

Percent effort	12-month (CY) appointment	9-month (AY) appointment	3-month summer (SM) term
5%	0.60 CY	0.45 AY	0.15 SM
10%	1.20 CY	0.90 AY	0.30 SM
15%	1.80 CY	1.35 AY	0.45 SM
20%	2.40 CY	1.80 AY	0.60 SM
25%	3.00 CY	2.25 AY	0.75 SM
35%	4.20 CY	3.15 AY	1.05 SM
50%	6.00 CY	4.50 AY	1.50 SM
100%	12.00 CY	9.00 AY	3.00 SM

Worked examples, directly from NIH’s own guidance:

• 10% effort on a 12-month (CY) appointment = 0.10 × 12 = 1.2 CY person-months.
• 35% effort on a 3-month summer (SM) term = 0.35 × 3 = 1.05 SM person-months.
• 10% effort on a 0.5-FTE, 12-month appointment = 0.10 × 12 × 0.5 = 0.6 CY person-months (the FTE fraction applies when the appointment itself is part-time, on top of the effort percentage devoted to the project).

A person-months figure is only meaningful alongside its appointment-type label — 3.0 person-months means something very different on a CY appointment (25% effort) than on an AY appointment (33% effort) or a 3-month SM term (100% effort). Always report the type, not a bare number.

Committed effort vs. actual effort

Committed effort is the level of effort proposed in the application and stated in the Notice of Award — the number a PI and their institution agreed to deliver in exchange for the funding. Actual effort is what the internal-control/certification process documents as having really happened. The two are allowed to diverge modestly without triggering any federal action; they are not allowed to diverge so far, so often, or so directionally that the committed figure becomes fiction.

Two mechanics matter here:

• The prior-approval threshold. A reduction of 25 percent or more in the PD/PI’s committed level of effort from what was approved at the time of award requires prior sponsor approval before the reduction takes effect — commonly cited as NIH Grants Policy Statement guidance on Level of Effort. This is a PD/PI-specific rule; check the specific award’s terms and the sponsoring agency’s own policy statement for the exact threshold and whether it extends to other key personnel, since agencies vary.
• The 100%-of-IBS ceiling across all simultaneous commitments. A person’s total committed effort across every award, institutional duty, and outside commitment cannot exceed 100% of their compensated activity. Overcommitment — proposing 30% effort to three different simultaneous federal awards for the same individual, for example — is one of the most common findings in federal audits and program-integrity reviews, precisely because it’s arithmetically impossible to certify as actual effort later. See Faculty Effort Allocation Across Multiple Grants for the full mechanics of managing this across a portfolio.

Worked calculation: applying the NIH salary cap to certified effort

The salary cap does not change how effort is calculated — it changes how much of the salary tied to that effort a federal award will actually reimburse. NIH’s cap limits the salary rate chargeable to an NIH grant, cooperative agreement, or extramural R&D contract to Executive Level II of the Federal Executive Pay Schedule, currently $228,000 annually, effective January 1, 2026 (up from $225,700 for calendar year 2025), per NIH Guide Notice NOT-OD-26-034, with the effective date corrected from January 11 to January 1, 2026 by follow-up notice NOT-OD-26-038. See NIH Salary Cap 2026 for the cap’s full history and how it applies to indirect as well as direct salary costs (a scope expansion effective October 1, 2024). This guide applies the cap to a specific certification scenario rather than repeating that history.

Example. A faculty member has an IBS of $260,000 on a 12-month (CY) appointment and commits 20% effort to an NIH-funded project.

1. Uncapped person-months and salary: 20% × 12 = 2.4 CY person-months committed. Uncapped salary attributable to that effort: 20% × $260,000 = $52,000.
2. Apply the cap: because IBS ($260,000) exceeds the $228,000 cap, the cap — not IBS — becomes the base for calculating the chargeable salary. Capped salary rate: $228,000. Chargeable salary at 20% effort: 20% × $228,000 = $45,600.
3. The gap: $52,000 − $45,600 = $6,400. NIH funds may not cover this difference. The institution must either absorb it from a non-federal, unrestricted source, or — where this is genuinely how the arrangement is documented and permitted under institutional policy — treat the excess as an above-the-cap cost-share contribution. It cannot simply be charged to the award, and it cannot be quietly shifted to another federal award as an accounting convenience — that pattern is exactly what cost-transfer scrutiny (see the Cost Transfer dictionary entry) exists to catch.
4. What gets certified: the individual’s effort certification still reflects the real 20% of their total professional activity that went to the project — the cap changes what NIH reimburses, not what effort actually happened or what gets attested to. Certifying a lower effort percentage than actually occurred, purely to make the capped salary “match,” misstates the record and is itself an audit finding.

Cost-shared and voluntary committed effort

Effort that is committed to a project but not charged to the federal award — because the sponsor requires matching/cost-sharing, or because the institution or PI voluntarily commits additional uncompensated effort in the proposal — still has to be documented and, where mandatory, tracked against the commitment, because it is part of the total project effort the award is being evaluated against. Two categories:

• Mandatory cost-shared effort: effort explicitly required as a condition of the award (a specific sponsor match requirement) or committed as a condition the institution accepted in the proposal. This must be tracked and reported the same as directly-charged effort, and it factors into the 100%-of-IBS ceiling above.
• Voluntary committed effort: effort the PI or institution offers in the proposal beyond what the sponsor requires, without corresponding salary charged to the award — for example, stating a PI will commit 10% effort at no cost to the project as a sign of institutional commitment. NIH and most other federal sponsors discourage this practice explicitly, for a straightforward reason: once stated in a competing application, voluntary committed effort becomes a real, trackable commitment subject to the same 100%-of-IBS-across-all-commitments arithmetic and the same audit expectation of consistency with what’s actually certified — with none of the offsetting federal funding to make it sustainable. A pattern of unfunded voluntary commitments is a documented source of both overcommitment risk and effort-certification inconsistency at award-closeout and audit time. The safer, sponsor-preferred practice is to propose only the effort the budget actually supports.

Summer salary for 9-month appointments

Faculty on a 9-month academic-year appointment are commonly compensated separately for research effort performed during the summer months outside that appointment, using the SM (summer months) person-months convention described above. Institutional policies vary on the specific number of summer months available (commonly 2 or 3), but the underlying compliance logic is constant: summer salary is still subject to the same institutional-base-salary ceiling, the same salary-cap rate limitation on federal awards, and the same 100%-of-total-compensated-activity ceiling — a faculty member cannot certify 100% summer effort across multiple awards that, combined, exceed the actual summer period available. Summer effort certifications are also a well-known audit-attention area specifically because the appointment period is short and the incentive to overcommit (multiple grants competing for the same 2-3 months) is real; documentation should tie the certified summer effort explicitly to calendar dates within the institution’s defined summer term, not just a percentage.

What auditors actually look for

Under Single Audit review (2 CFR 200 Subpart F — see The Single Audit) and agency-level program reviews, salary and wage charges to federal awards are consistently one of the highest-scrutiny cost categories, because they are both material in dollar terms and easy to test against independent evidence (payroll records, proposal budgets, Notices of Award, and — where used — signed certifications). Common findings include:

• Committed effort that was never reduced through prior approval despite an actual reduction of 25% or more, or reduced effort that was never reflected in reported person-months at all.
• Overcommitment — the sum of an individual’s committed effort across simultaneous awards and institutional duties exceeding 100% of their compensated activity, discoverable simply by adding up every current Notice of Award.
• Salary charged above the applicable cap, or the cap-related “gap” (see the worked example above) improperly absorbed by shifting cost to another federal award via an undocumented or late cost transfer.
• Certifications completed by someone without suitable means of knowledge of the individual’s actual activity — 200.430(g) implies the certifier has to actually be positioned to know what happened, not just sign a routed form.
• Stale or estimate-only records with no after-the-fact reconciliation — 200.430(g) explicitly permits budget-estimate-based charging, but only paired with a real periodic review and adjustment process; an institution that charges by estimate and never reconciles has not satisfied the standard even though estimate-based charging itself is allowed.
• Voluntary committed effort proposed but never tracked, making it impossible to demonstrate the total-project-effort picture the award was reviewed against.

The common thread across all of these: auditors are testing whether the institution’s system, whatever form it takes, produces records that are internally consistent — proposal, Notice of Award, payroll distribution, and certification all telling the same story about the same person’s time — not whether a specific named form was used.

Frequently asked questions

Is effort reporting still federally required?

The internal-control outcome is required (2 CFR 200.430(g)) — accurate, allowable, properly-allocated salary charges supported by records of total compensated activity. A specific named “effort reporting system” or certification form is not mandated by that regulation itself; most institutions still run a certification-based process because it’s a well-tested way to meet the standard, and a specific federal awarding agency retains authority under 200.430(g)(8) to require personnel activity reports from a given recipient if warranted.

What’s the difference between effort reporting and effort certification?

Effort reporting (or time-and-effort reporting) is the umbrella system — tracking, documenting, and reconciling how compensated time is distributed across activities. Effort certification is one specific mechanism within that system: a signed or formally attested statement, typically periodic, confirming that a given distribution of effort is accurate. See the Time and Effort Reporting and Effort Certification dictionary entries for the full distinction.

Do person-months have to add up to 12 across all of a person’s activities?

They have to add up to no more than the total months in the relevant appointment period across all compensated activity, not just the awards being certified. A 12-month (CY) appointee’s total committed and actual person-months across every source of compensated activity cannot exceed 12; a 9-month (AY) appointee’s cannot exceed 9, before any separately-compensated summer months are added.

Does the salary cap reduce how much effort a capped individual has to certify?

No. The cap limits what a federal award will reimburse for a given percentage of effort — it does not change the actual effort performed or the effort that must be certified. Certifying a lower percentage to make the capped dollar amount “look right” misstates the record.

Why do sponsors discourage voluntary committed effort?

Once stated in a proposal, voluntary committed effort is a real commitment subject to the same 100%-of-IBS overcommitment math and certification-consistency expectations as funded effort, but with no federal salary support attached to make it sustainable — creating audit and overcommitment risk without an offsetting funding benefit.
