TLDR
Payroll allocations must reconcile to time-and-effort certifications monthly — not quarterly, despite common practice. Under 2 CFR 200.430, the after-the-fact confirmation principle requires that payroll charges reflect the actual time worked on each activity, not the budgeted percentages. An organization that posts payroll at the budgeted split and reconciles annually creates a full year of questioned costs if the actual time differed materially from the budget.
Payroll allocation across multiple grants is, for most mid-sized nonprofits, the single largest category of federal expenditure and the single largest source of audit findings. Personnel costs are both the easiest thing to misallocate and the hardest thing to correct after the fact. The combination — high dollar value, complex allocation rules, monthly cadence — makes this workflow one worth running well.
When to run this workflow
Run this workflow every month-end, timed to follow the payroll closing for the period. For organizations on a biweekly pay schedule, the month-end payroll allocation may cover two or three pay periods. The allocation must be posted and reconciled to time records before the monthly grant financial reports go to funders — not after.
Also run this workflow whenever a staff member’s grant assignment changes. A program manager moving from 40% to 60% on a specific grant requires an immediate update to the payroll allocation going forward, plus confirmation that prior months’ allocations reflected the actual time worked during those months.
Common pitfalls
Posting at budgeted percentages without checking actual time. The most common and most expensive error. The budget says 60% — the employee actually worked 45% on the grant that month. The difference is a questioned cost unless caught and corrected monthly.
Using the prior month’s allocation without updating for personnel changes. Many organizations copy last month’s allocation each month. If an employee left mid-month or a new grant started, the copy-forward produces incorrect allocations immediately.
Charging indirect costs on top of already-indirect costs. The MTDC base typically excludes indirect costs themselves. Adding indirect charges to a base that includes prior indirect charges creates circular and incorrect charges. Verify the MTDC calculation annually.
Missing the monthly reconciliation to time records. Allocating payroll and posting the entry is not the end of the process. The posted percentages must match the certified time records. Organizations that treat posting as completion and reconciliation as optional discover the gap only when auditors test time-and-effort documentation.
Audit trail requirements
Payroll allocation audit evidence includes:
- Payroll registers for each pay period covered by the allocation
- The allocation worksheet showing employee-level grant distribution
- Time records (time sheets, activity reports, or dual-signature certifications) for each employee for the period
- Reconciliation showing that allocation percentages equal certified time percentages
- Budget-vs-actual showing cumulative salary charges against approved grant salary budgets
- Any correcting journal entries with supporting rationale and sign-off
Auditors testing compensation charges under Single Audit will request all of these for a sample of employees and pay periods. The audit is a lot easier when the documentation exists and is organized in advance.
How GrantPipe automates this
GrantPipe connects payroll allocation data to grant budgets in real time, so cumulative salary charges update each month and the budget-vs-actual is always current. Allocation percentages are compared to time-and-effort records as they are certified, and discrepancies flag before the monthly close rather than at audit. Start a trial.

- After-the-fact confirmation
- The 2 CFR 200.430 principle requiring that payroll charges to federal awards reflect actual time worked, verified by time records, rather than prospective budgeted allocations.
DEFINITION
- Modified Total Direct Costs (MTDC)
- The base used to calculate indirect cost charges under federal awards. Includes direct salaries, wages, and fringe, but excludes equipment, capital costs, patient care, tuition, and participant support costs.
DEFINITION
- Semi-annual certification
- A time-and-effort certification covering six months at once, permitted under 2 CFR 200.430(i) only for employees who work exclusively on a single federal award or cost objective — not employees split across multiple awards.
DEFINITION
- Fringe benefit pool
- An organization-wide fringe rate applied uniformly to all salary charges, calculated as total fringe benefits divided by total salaries. Used as an alternative to tracking actual fringe by employee when the organization has a relatively uniform benefit structure.
DEFINITION
Q&A
What documentation does an auditor expect for payroll allocations?
The auditor expects: payroll registers for each pay period, the payroll allocation worksheet showing how each employee's pay was distributed across grants, the time-and-effort records (time sheets or activity reports) that support the allocation percentages, monthly reconciliation documentation showing that posted percentages match certified time, and budget-vs-actual showing cumulative salary charges against approved grant budgets.
Q&A
How do we handle a retroactive payroll correction?
Retroactive payroll corrections must be processed within 90 days of the original payroll for timely correction, per prevailing federal agency guidance. The correcting journal entry requires additional justification for corrections older than 90 days. Document the reason the correction was not caught earlier, the support for the corrected allocation, and the review sign-off. Late corrections raise questions about monitoring effectiveness.
Q&A
Do we need separate accounts for each grant's payroll charges?
Not necessarily separate GL accounts, but grants must be trackable at the level of detail needed for reporting. Whether you use segment-level grant codes, dimension tags, or a true fund accounting structure depends on your accounting system. What matters is that the detail behind any grant-level salary report is auditable to individual employees and pay periods.
