What are DCAA Audit Requirements?

Definition

DCAA Audit Requirements are the accounting, documentation, internal control, labor charging, cost allocation, and recordkeeping expectations that government contractors may need to demonstrate during a Defense Contract Audit Agency audit. The requirements help auditors evaluate whether reported costs are supported, properly classified, consistently accounted for, and traceable to reliable source records.

A practical understanding of these requirements helps contractors organize evidence before an audit and maintain accounting processes that support accurate contract costing, billing, indirect rate calculations, and financial reporting.

Core DCAA Audit Requirements

DCAA audit requirements vary according to the audit objective, contract circumstances, and accounting system being examined. A contractor's preparation should generally address the integrity of its accounting records, cost treatment, labor systems, and supporting documentation.

  • Accounting records: Maintain an organized general ledger, supporting schedules, reconciliations, and transaction-level documentation.
  • Labor charging: Maintain accurate timekeeping, labor distribution, approvals, and documented corrections.
  • Cost allocation: Apply consistent methods for assigning direct and indirect costs to contracts and other activities.
  • Procurement records: Preserve requisitions, purchase orders, invoices, receiving evidence, approvals, and payment records.
  • Audit evidence: Maintain documentation that allows reported amounts and accounting decisions to be traced back to source transactions.

Labor and Timekeeping Requirements

Labor charging is a critical part of DCAA audit preparation because employee time can directly affect contract costs and indirect cost pools. Contractors should maintain a system in which employees record time accurately and supervisors review and approve time records according to established procedures.

The DCAA Timekeeping & Labor Cost Tracking Guide provides additional educational context on DCAA timekeeping requirements, labor cost tracking practices, compliance considerations, and maintaining audit readiness.

Labor corrections should also be documented so that the original entry, correction, reason, authorization, and resulting accounting treatment can be understood. Consistent procedures help connect timekeeping records with payroll, labor distribution, and contract cost reporting.

Cost, Procurement, and Transaction Requirements

DCAA reviews can require contractors to demonstrate how costs move from source transactions into accounting records and contract reports. Procurement documentation should therefore connect approved spending to the resulting invoice, receipt, payment, and accounting entry.

A purchase order process can establish authorization and spend controls before a supplier transaction is recorded. The associated records should show who requested the purchase, who approved it, what was purchased, and how the transaction was ultimately recorded.

Tax treatment can also require supporting evidence. When reviewing jurisdiction rules, exemptions, nexus, or potential overcharges, contractors should retain documentation supporting tax validation and accounting treatment, including relevant use tax considerations.

Accruals, Invoices, and Audit Trails

Period-end accounting requires particular attention because accruals can affect reported contract costs and financial statements before related invoices or payments are processed. Supporting calculations, approval records, posting dates, reversals, and subsequent settlement should be traceable.

Audit Trails For Accruals can provide a record of accrual processing steps and approvals, supporting review of how an accrual was created and subsequently handled. Vendor payment activity can similarly be supported through Audit Trails For PO, which help trace actions associated with purchase orders, approvals, payments, and reconciliation.

For invoice processing, Audit Trails can preserve information about actions, timestamps, and data changes, creating a transaction history that supports financial review. Sales tax workflows can use Audit Trails for Sales Tax Verification to document verification activity and related journal-entry actions.

ERP and Financial System Requirements

The accounting system should support reliable transaction processing, consistent cost classification, controlled access, reconciliations, and traceable financial reporting. Contractors evaluating an ERP can use the DCAA-Compliant ERP: 2026 Buyer's Guide + AI Audit Tips to examine capabilities relevant to DCAA compliance and year-round audit readiness.

ERP implementation also affects how evidence is retained across integrations and finance workflows. A contractor should evaluate how transactions move between procurement, accounts payable, payroll, general ledger, and reporting modules while preserving appropriate records.

Invoice and transaction documentation should remain connected to the corresponding accounting entries. This allows reviewers to follow financial activity from source documentation through processing, posting, reconciliation, and reporting.

Documentation and Reporting Requirements

DCAA audit preparation depends on more than maintaining accounting entries. Contractors should be able to produce supporting documentation that explains significant balances, adjustments, cost allocations, labor charges, and other financial information requested for the applicable audit.

E Invoice Requirements are another example of documentation considerations that can affect finance workflows, particularly where electronic invoice data must support processing, verification, and record retention.

Disclosure Requirements can also become relevant when financial information, accounting policies, or other required information must be presented transparently. Similarly, Reporting Requirements help establish what data must be organized and presented for specific reporting and analytics workflows.

Maintaining DCAA Audit Readiness

Meeting DCAA audit requirements is an ongoing accounting discipline rather than a one-time preparation exercise. Contractors can maintain readiness by assigning ownership to key controls, periodically reviewing supporting evidence, reconciling accounts, and updating procedures when systems or contract requirements change.

ERP governance should also be reviewed when implementing new integrations, migrating financial data, or extending workflows. The ERP for Government Contractors: The Complete Guide (2026) provides broader guidance on government-contractor ERP capabilities, DCAA compliance considerations, and implementation practices.

A consistent review process makes it easier to identify documentation gaps, verify that accounting policies are being followed, and demonstrate how financial transactions support reported contract costs.

Summary

DCAA Audit Requirements center on accurate accounting records, reliable labor charging, consistent cost allocation, procurement documentation, supporting evidence, internal controls, and traceable financial transactions. Contractors that organize these requirements into recurring finance and compliance workflows can maintain stronger audit readiness and support dependable contract cost reporting.
