9 Grant Compliance Mistakes That Produce Audit Findings (and How to Prevent Each)

Federal Single Audit findings in the allowable costs and activities-allowed categories represent a significant share of the recurring findings in the Federal Audit Clearinghouse. These nine mistakes produce those findings — not through negligence but through systems that could not enforce the rules automatically and through practices implemented after a problem appeared rather than before the grant period started.

Mistake 1: No Formal Award Setup Process — Expenses Start Before a Fund Code Exists

The mistake: A grant award letter arrives, the executive director forwards it to program staff with congratulations, and program activities begin charging to the operating budget because the restricted fund code has not been set up yet. Accounting creates the fund code two weeks later and reclassifies the expenses retroactively.

Why it happens: Award setup is not a defined workflow. There is no checklist that must be completed before spending begins. The program team sees an approved project and starts working; the finance team learns about the award on the next budget-to-actual report cycle.

The consequence: Retroactive reclassification creates an audit trail showing journal entry corrections after the fact. Auditors examining the award’s expenditure documentation see entries that were originally coded to operating accounts and then moved — which raises the question of whether the costs were actually allocable to the grant or were charged because funds were available. This is a common trigger for a more detailed cost examination under 2 CFR 200.405.

The fix: Create a written Award Setup Checklist that must be completed before any expenditure is authorized against a new award. The checklist should include: assign a fund code in the accounting system, set up the approved budget in the grant management system line by line, enter all reporting deadlines in the compliance calendar, and obtain a countersigned authorization from the finance director. The award is not active for spending purposes until the checklist is signed off.

Mistake 2: Budget Modifications Made Without Written Funder Approval

The mistake: Program expenses in a specific budget category exceed the approved amount — commonly personnel costs or supplies — and the grants manager or program director shifts spending from an underspent category to cover the overage without requesting funder approval.

Why it happens: The threshold for requiring prior approval is buried in the award terms and conditions. Staff who have general authorization to approve program expenditures assume that budget flexibility applies at the grant level the same way it applies at the organizational level. The organization’s internal policy does not reference grant-specific prior approval requirements.

The consequence: An unauthorized budget modification is an Audit Finding under the category “Period of Performance/Budget Restrictions.” If the reallocation exceeded the award’s allowable flexibility threshold — typically 10% of the total award for federal grants — the moved funds may be disallowed, requiring repayment. Disallowances of $10,000–$75,000 from a single grant are common when this mistake is discovered in a Single Audit.

The fix: Add a budget modification review step to your monthly grant reconciliation process. When any budget category is tracking more than 5% above or below budget at the midpoint of the award period, the grants manager reviews the applicable prior approval requirements from the award agreement. Any reallocation above the stated threshold triggers a modification request to the program officer before the expenditure is made.

Mistake 3: Expense Allocation Based on Estimates, Not Actual Activity

The mistake: The organization allocates indirect costs — or sometimes direct costs such as staff time and shared supplies — to grants using a predetermined estimate at the beginning of the year and never adjusts the allocation as actual activity changes throughout the year.

Why it happens: Allocation calculations are done once during budget preparation, treated as fixed, and left in place for the entire award period. The finance team applies the same allocation percentages month after month regardless of what program staff are actually doing.

The consequence: If an auditor requests support for cost allocations and the organization cannot show that allocated costs reflect actual benefit received by each program, the allocation methodology fails the allocability test under 2 CFR 200.405. Costs that cannot be shown to benefit the grant from which they are charged are disallowed. This is particularly common when an organization allocates executive director or finance staff time to a grant using a flat percentage that does not vary with actual grant-related work.

The fix: Document the allocation methodology in writing before the award period starts. For indirect cost pools, either use a federally negotiated indirect cost rate agreement or establish a written cost allocation plan that describes how indirect costs are distributed across programs. For direct costs charged based on time, use actual time records — not estimates — as the basis for allocation. Review and update allocations quarterly when actual activity deviates significantly from the original estimate.

Mistake 4: Missing Time-and-Effort Documentation for Personnel Charged to Grants

The mistake: Employees whose salaries are partially or fully charged to a federal grant do not maintain time records that document hours worked on grant-funded activities. The payroll allocation is set in the accounting system at a fixed percentage and no supporting documentation is generated by the employee.

Why it happens: Time-and-effort documentation requirements are frequently misunderstood as applying only to hourly employees. Salaried employees charged to federal grants are equally subject to the requirement under 2 CFR 200.430(i). Organizations that have never been audited often do not know the documentation does not exist until a auditor requests it.

The consequence: Missing time-and-effort documentation for personnel charged to federal awards is one of the top five audit findings in the Federal Audit Clearinghouse. When auditors cannot verify that an employee actually worked on grant-funded activities in proportion to the charges recorded, the full salary allocation to the grant is at risk of disallowance. A single finding covering one position at 50% effort over a two-year award period can result in a disallowance exceeding $100,000.

The fix: Require every employee with any federal grant allocation to maintain a timesheet or effort report that identifies the percentage of time worked on each grant by pay period. The report should be signed by the employee and reviewed and approved by a supervisor with direct knowledge of the employee’s work. Monthly is the maximum acceptable interval; biweekly is better. Store signed time records in the grant file alongside the payroll documentation.

Mistake 5: Reporting Period Dates That Don’t Match the Accounting Period

The mistake: The financial report submitted to the funder for the period January 1 through March 31 does not match the general ledger for the same period because the organization’s accounting system uses a fiscal year that does not align with the grant reporting period, and month-end close entries from March were not captured before the report was submitted.

Why it happens: The person preparing the grant financial report pulls figures directly from the accounting system before the period-end close is complete. Unpaid invoices, accrued salaries, and indirect cost entries that belong to the reporting period are either missing or included in the wrong period.

The consequence: A financial report that materially misrepresents expenditures during the reporting period is an inaccurate report under 2 CFR 200.327. When auditors reconcile reported expenditures against the general ledger and find discrepancies, they generate a reporting finding and may expand their examination of the entire award. Inaccurate interim reports also create problems at closeout, when the cumulative reported amounts must match the final expenditures exactly.

The fix: Establish a firm rule that grant financial reports cannot be prepared until the accounting period is fully closed. Build a reporting calendar that staggers the report due date at least two weeks after the period-end close date. If a funder’s report due date falls before close can be completed, contact the program officer and request a brief extension — funders grant extensions for this reason regularly.

Mistake 6: Unallowable Costs Charged to Federal Awards

The mistake: The organization charges costs to a federal award that are explicitly unallowable under 2 CFR 200.420–475: staff meal expenses from meetings, alcohol purchased at a fundraising event partially charged to a federal grant, lobbying costs coded to a restricted fund, entertainment expenses, or fines and penalties.

Why it happens: Finance staff apply the organization’s general expense categories to grant expenditures without checking whether specific costs are allowable under the Uniform Guidance. The most common version: a staff member submits a receipt for a business lunch during a grant-funded activity, it gets coded to the grant, and no one in the approval chain checks the allowability of the specific cost type.

The consequence: Unallowable costs charged to federal awards are a direct disallowance finding. The organization must repay the disallowed amount to the federal agency. Meal and entertainment costs are the most frequently cited unallowable items, but the disallowance amount is usually small. Lobbying expenses, however, can result in suspension of award if the charge is material.

The fix: Create a one-page unallowable cost reference card based on 2 CFR 200.420–475 and include it in the onboarding packet for any staff who submit expense reports. The card should list the most common unallowable types: alcoholic beverages, entertainment costs, lobbying, fundraising, fines, interest on loans (except certain capital financing), and costs of activities that violate federal law. Add a field to your expense reimbursement form that requires the approver to confirm the expense is allowable under applicable award terms.

Mistake 7: No Subrecipient Monitoring System for Pass-Through Awards

The mistake: The organization passes a portion of a federal award to a subrecipient organization but does not conduct the required risk assessment, establish subaward agreements with required federal flow-down clauses, or perform ongoing monitoring of the subrecipient’s programmatic and financial performance.

Why it happens: Pass-through awards are treated as grant disbursements rather than compliance relationships. The primary grantee sends the funds, receives invoices, and pays them — without recognizing that 2 CFR 200.331–332 places specific monitoring obligations on the pass-through entity that cannot be delegated to the subrecipient.

The consequence: Subrecipient monitoring findings are among the highest-severity findings in federal Single Audits. If a subrecipient spends federal funds inappropriately and the primary grantee cannot demonstrate it conducted required monitoring, the primary grantee bears the financial liability for the subrecipient’s disallowed costs. The pass-through entity is the responsible party to the federal agency — the subrecipient’s compliance failure becomes the primary grantee’s audit finding.

The fix: Create a subrecipient monitoring checklist for every pass-through award. The checklist must include: a pre-award risk assessment of the subrecipient’s financial management capacity, a written subaward agreement that includes all required federal flow-down clauses, periodic monitoring of subrecipient expenditures (at minimum, desk review of invoices and financial reports; for higher-risk subrecipients, on-site visits), and documentation of monitoring activities in the grant file. The monitoring requirement exists whether the subrecipient is another nonprofit, a government agency, or a university.

Mistake 8: Drawdown Timing That Violates Cash Management Requirements

The mistake: The organization draws down federal funds in advance of immediate cash need, holds them in an interest-bearing account, and uses them for general operating purposes before applying them to grant expenditures.

Why it happens: Staff treat federal drawdowns as a cash flow tool — drawing when the organization’s cash balance is low, regardless of whether grant expenditures have been incurred. The requirement that federal cash advances be drawn only for immediate cash needs within three days of expenditure (per the Cash Management Improvement Act and OMB requirements) is not built into the drawdown approval process.

The consequence: Earning interest on advanced federal funds without remitting that interest is a Cash Management finding under 2 CFR 200.305. The interest must be returned. Holding advanced federal funds also creates fiduciary risk — if those funds are spent on unallowable costs, the entire advance must be repaid.

The fix: Establish a written drawdown policy requiring drawdowns to be tied to actual incurred expenditures within the prior 72-hour window. The staff member submitting drawdown requests must document the expenditure basis — not just the funding period or award number. Review drawdown timing in the monthly grant reconciliation to verify amounts match actual general ledger expenditures for the corresponding period.

Mistake 9: Records Destroyed Before the Three-Year Retention Period Ends

The mistake: The organization purges paper files or deletes electronic records from closed grants as part of routine records management, without verifying that the three-year retention period from the final expenditure report date has expired.

Why it happens: Records management policies use the grant end date as the retention trigger rather than the final expenditure report submission date. A grant with a June 30 end date may have a final expenditure report due 90 days later — the retention clock starts on that report submission date, not June 30. Organizations using the end date are destroying records early at minimum.

The consequence: Under 2 CFR 200.334, premature destruction is itself a finding if an auditor or OIG requests records that should exist but have been destroyed. If a subrecipient’s audit extends past the primary grantee’s retention period and the primary grantee has already destroyed supporting documentation, the primary grantee has no defense. Record destruction findings can result in the full award being treated as unallowable.

The fix: Build the retention date into every grant record at closeout: calculate three years from the final expenditure report submission, enter it in the grant management system as a “retain until” date, and set a 60-day automated reminder. Destroy records only after the calculated retention date has passed and no audits or litigation holds apply. Store the final expenditure report submission confirmation as the document that starts the retention clock.
