Payroll is often one of the largest grant costs, yet salary charges can become difficult to explain when staff work across several projects or allocations change during the year. A payroll reconciliation helps an NGO confirm that donor-funded salary costs match employment records, time-allocation evidence and the accounting ledger.
Start with the approved staffing budget
List the positions, salary assumptions, percentage allocations and grant periods the donor approved. If the project later changes staffing or salary allocation, document the reason and any approval required before treating the new pattern as permanent.
Reconcile payroll to the ledger
Each month, compare the payroll register with the amounts posted to the grant. Confirm that the correct employees, gross salaries, employer costs and deductions were recorded. Investigate duplicate charges, missing employees or unexplained differences.
Check staff allocation evidence
If staff work across multiple grants, confirm that the allocation method is documented and applied consistently. Timesheets or equivalent effort records should support the charge where required. See timesheets for grant-funded staff for a practical guide.
Review changes in staffing
Vacancies, promotions, salary adjustments, leave and staff transfers can affect grant costs. Do not assume the original proposal allocation remains accurate throughout implementation. Update forecasts and determine whether a budget revision or donor notification is required.
Useful monthly checks
- Payroll agrees to the general ledger.
- Only eligible staff are charged.
- Allocation percentages are supported.
- Employer costs are calculated correctly.
- Vacancies and changes are reflected in forecasts.
- Corrections are documented.
- Donor-specific limits are respected.
Example
A program officer was budgeted at 50 percent to one grant but spends most of a quarter supporting a different award. If the organization continues charging the original percentage without checking its approved allocation method, the payroll cost may be difficult to defend. The issue should be identified during monthly reconciliation rather than at audit.
Keep corrections traceable
If a salary was charged to the wrong grant, correct the entry through the normal accounting process and retain an explanation. Avoid unexplained journal transfers between projects because they weaken the audit trail.
What to do next
Use the Grant Evidence Inventory to check whether payroll, contracts and allocation evidence are organized and current.

Reconcile payroll taxes and benefits too
Salary cost is not only basic pay. Employer taxes, pension, insurance and other benefits may also be charged to the grant if allowable. Confirm that these costs follow the approved basis and are not duplicated across grants.
If the donor caps salary or benefit rates, compare actual payroll against those limits before reporting. Differences should be corrected promptly rather than carried forward through repeated journal adjustments.

During closeout, compare the final payroll allocation with the approved staffing budget and any donor-approved changes. Resolve outstanding corrections before the final financial report so salary costs do not shift after submission.
Keep the final payroll reconciliation with the grant audit file, together with employment records and allocation evidence required by the donor.
For grants with several staff allocations, a simple payroll summary by employee and grant can make monthly review faster and help managers spot unusual changes before the donor report is prepared.
Frequently asked questions
What should a payroll reconciliation compare?
Compare payroll records, approved salaries, benefits, staff allocation, time or effort support where required, and the grant budget.
How often should payroll be reconciled?
Monthly is a common control for active grants, with additional review after staffing or salary changes.
Who should perform the reconciliation?
Finance should lead it with HR and program managers validating staff status and level of effort.
What are common payroll errors?
Wrong grant allocation, outdated salary rates, duplicate charges, incorrect benefits, or continued charging after staff changes are common issues.
What should happen when an error is found?
Correct it through the approved accounting process, preserve the explanation and approval, and assess whether reports or donor communication are affected.
Conclusion
Payroll reconciliation keeps one of the largest grant cost categories aligned with reality. Your organization should match payroll to approved staffing, budgets, and supporting records every month and correct discrepancies transparently.
