What a Timekeeping Audit Examines
A timekeeping audit typically evaluates the complete process from recording hours through approval and accounting. Auditors may review a sample of employees, pay periods, projects, and adjustments to determine whether the records accurately represent work performed.
- Time entry accuracy: Whether employees record actual hours worked using approved procedures.
- Cost allocation: Whether labor is charged to the correct contract, project, department, or indirect cost category.
- Approvals: Whether supervisors review and approve time records within established workflows.
- Corrections: Whether changes to submitted time are properly documented, authorized, and traceable.
- Payroll reconciliation: Whether approved time records agree with payroll and labor distribution information.
Timekeeping Compliance and Labor Charging
Timekeeping Compliance describes the practices and controls used to ensure employees record and report time according to applicable organizational, contractual, regulatory, and accounting requirements. Compliance is particularly important when labor charges affect contract costs or reimbursement.
Employees should understand how to distinguish direct and indirect work, select the correct cost objective, record time consistently, and report corrections through approved procedures. Supervisors should understand their responsibility for reviewing entries rather than simply approving records without examination.
For government contractors, the DCAA Timekeeping & Labor Cost Tracking Guide provides educational guidance on DCAA timekeeping requirements, labor cost tracking practices, compliance rules, and maintaining audit readiness.
Audit Evidence and Traceability
A timekeeping audit depends on evidence that allows an auditor to trace labor information from the original employee entry through approval, payroll processing, accounting, and reporting. A documented Audit Trail can establish who performed an action, when it occurred, and what information changed.
Broader Audit Trails can capture timestamps, user actions, and data changes within invoice and financial workflows, providing additional transaction-level traceability. For procurement-related payments, Audit Trails For PO can preserve records of actions surrounding vendor payments, approvals, automation, and reconciliation.
Accrual records also require clear supporting evidence when labor or other costs are recognized before final invoices or payroll-related information is available. Audit Trails For Accruals can document steps and approvals associated with the accrual process, while properly supported accruals help align expenses with the appropriate accounting period.
Timekeeping, Accounting, and Tax Controls
Timekeeping information ultimately affects financial reporting because labor hours can flow into payroll, cost accounting, project reporting, and general ledger postings. Accurate gl coding helps ensure transactions are assigned to appropriate accounts and cost categories during accounting workflows.
Tax controls may also intersect with broader financial audit procedures. When transactions require tax validation, organizations should evaluate jurisdiction rules, applicable exemptions, nexus, and tax treatment to support accurate reporting. Proper sales tax validation can help maintain reliable records and documentation for tax-related audit exposure.
Similarly, use tax considerations may arise when purchases or taxable transactions require additional tax assessment. Finance teams should retain the underlying transaction and jurisdictional evidence needed to support the treatment applied.
Where timekeeping and financial information are processed through integrated systems, a System Audit can complement a timekeeping review by examining system configurations, access controls, data flows, and processing rules that influence financial records.
How a Timekeeping Audit Is Performed
The audit generally begins by defining the review period, population, cost objectives, and applicable policies. The auditor then selects records for testing and compares employee time entries with supporting payroll, project, contract, and accounting information.
Interviews and operational observations can provide additional evidence about how employees actually record time. Auditors may ask employees to explain their assignments, charging decisions, correction procedures, and approval workflows. Differences between documented policies and actual practices can then be investigated and addressed.
- Define the audit scope, period, employee population, and applicable requirements.
- Select representative timekeeping records and supporting documentation.
- Trace selected entries through approval, payroll, labor distribution, and accounting.
- Review adjustments, corrections, and unusual timekeeping patterns.
- Document findings and maintain evidence supporting the audit conclusion.
Best Practices for Timekeeping Audit Readiness
Audit readiness improves when timekeeping controls operate consistently throughout the year rather than being reviewed only when an audit is scheduled. Organizations should provide clear employee guidance, maintain documented approval procedures, reconcile labor records regularly, and investigate unusual changes promptly.
System access should also follow defined responsibilities so employees and supervisors can perform only the actions appropriate to their roles. Periodic reviews of configuration and user activity can reinforce accountability and data integrity.
Automated workflows can strengthen traceability by recording approvals, timestamps, corrections, and related accounting events. Consistent documentation makes it easier to connect operational activity with reported labor costs and financial performance.
Summary
A Timekeeping Audit evaluates whether employee time records accurately reflect work performed and whether labor costs are properly classified, approved, allocated, and reported. Effective audits combine employee-level testing with payroll reconciliation, accounting review, system controls, tax validation, and documented audit trails. Strong timekeeping practices support accurate labor reporting, contract compliance, financial reporting, and ongoing audit readiness.
