Getting DCAA Audit-Ready in Q1: A Year-End Close Checklist for Government Contractors

The calendar flips to January, and for government contractors, that means one thing: incurred cost submission season is approaching, and DCAA will be watching.

Most contractors spend December scrambling to close their books and then spend January panicking about whether their numbers will hold up under audit scrutiny. That’s the wrong approach. The contractors who sail through DCAA reviews are those who systematically prepare in Q1 rather than reactively fix problems discovered mid-audit.

If you’re performing cost-reimbursement contracts, your incurred cost submission is due within six months after your fiscal year ends. For calendar year contractors, that means a June deadline that feels far away right now but arrives with shocking speed once you factor in the preparation time required.

Use Q1 to get genuinely audit-ready rather than just crossing your fingers and hoping DCAA doesn’t find anything.

Understanding What DCAA Actually Reviews

Before you start preparing, you need to understand what DCAA is looking for during an incurred cost audit. According to DCAA guidance, they evaluate whether your actual indirect rates were calculated correctly, whether costs claimed are allowable under FAR Part 31, whether your cost accounting practices were consistent with your disclosed practices, and whether you have adequate supporting documentation for all costs.

They’re not trying to catch you in fraud. They’re verifying that the costs you billed to the government throughout the year are legitimate, properly allocated, and compliant with regulations. However, inadequate preparation makes you look careless or worse, even when your costs are legitimate.

The contractors who receive clean audit opinions are those whose records tell a clear, consistent story, supported by organized documentation. That doesn’t happen by accident in May. It happens through systematic preparation starting in January.

Your January Year-End Close Tasks

January is when you finalize your fiscal year close and ensure all costs are appropriately recorded and allocated. This isn’t just about balancing accounts. It’s about creating a foundation that supports audit defense.

Complete All Reconciliations

Every account must be reconciled with external documentation. Bank accounts should reconcile to bank statements; credit card accounts to statements; payroll accounts to payroll reports and tax filings; and loan balances to lender statements. According to the DCAA Contract Audit Manual, auditors will verify these reconciliations, and unexplained differences raise red flags that extend audit timelines.

Don’t just reconcile and move on. Document why any differences exist and how you resolved them. If you identified errors, show the correcting entries. If there are timing differences, explain them clearly. DCAA wants to see that you understand your numbers, not just that they eventually balance.

Review and Finalize Indirect Rate Calculations

Your indirect rates are the mathematical result of dividing cost pools by allocation bases. By January, you should have actual numbers for both. Calculate your final fringe, overhead, and G&A rates using actual year-end data.

Compare these final rates to the provisional billing rates you used throughout the year. If there are significant differences, you need to understand why. Did your cost structure change? Did revenue mix shift? Did you have unexpected expenses? Document the variance analysis because DCAA will ask about it.

Per FAR 31.203, your indirect cost pools may include only costs that are reasonable, allocable, and allowable. This is the time to review every cost in your pools and verify that it meets these tests.

Identify and Segregate Unallowable Costs

This is where contractors frequently create problems for themselves. FAR 31.205 lists dozens of cost categories that are expressly unallowable or allowable only under specific conditions. Common unallowables include entertainment expenses, advertising costs that don’t meet FAR criteria, contributions and donations, excessive executive compensation, interest expense on borrowings, and penalties and fines.

Your accounting system should identify unallowable costs as they’re incurred, but January is when you systematically review the entire year to catch anything that slipped through. Create schedules showing unallowable costs by category, how much you excluded from each indirect pool, and the impact on your final indirect rates.

The DCAA ICE Model includes specific schedules for unallowable costs. Preparing these schedules in January gives you time to research questionable items and document your decisions before submission.

Verify Timekeeping Compliance

For most contractors, labor is the largest cost category, which means it gets the most audit attention. DCAA has strict requirements for timekeeping systems under FAR 31.201-2 and DCAA guidance. Your timesheets must account for all hours worked, be prepared contemporaneously, be signed by employees, and support the labor distribution to contracts and indirect accounts.

In January, review a sample of timesheets from throughout the year. Verify they were completed daily or at least within a reasonable period. Check that supervisory approvals are documented. Confirm that hours allocated to contracts reconcile to payroll records and contract billing.

If you find gaps or inconsistencies, document them and implement corrective actions before DCAA discovers them. It’s far better to self-identify issues and show you corrected them than to have auditors find problems you didn’t know existed.

February: Organize Your Documentation

With your close finalized and rates calculated, February is when you organize the documentation that supports every number in your incurred cost submission.

Create Your Audit Support File

Think of this as building the case file that proves your costs are legitimate. For each indirect cost pool, you need supporting schedules showing costs by general ledger account, allocation base calculations, rate computations, and reconciliation to financial statements.

For significant cost categories, gather supporting documentation, such as vendor invoices for major purchases, lease agreements for facilities costs, insurance policies and premium invoices, employee benefit plan documents and costs, and depreciation schedules for equipment and vehicles.

The DCAA ICE Model provides a standardized format for incurred cost submissions, but the model itself is just the summary. Behind it, you need detailed support for every number. Organize this documentation by cost pool and category to respond quickly to audit requests.

Document Your Cost Accounting Practices

DCAA will compare your actual practices to your disclosed practices. If you’re CAS-covered, that means comparing to your CAS Disclosure Statement. If you’re not CAS-covered, it means comparing to your accounting policies and any representations made in proposals or contract negotiations.

Document your cost accounting period, allocation methodologies for each indirect pool, criteria for direct versus indirect cost treatment, unallowable cost identification process, and any changes in practices during the year.

If you changed any accounting practices during the year, you need clear documentation of what changed, why it changed, when it changed, and the impact on your rates. Under Cost Accounting Standards, changes in accounting practices require disclosure and, in some cases, contract adjustments.

Prepare Variance Explanations

Your provisional billing rates never exactly match your final rates. DCAA will want to understand why. Prepare written explanations for significant variances that address what caused the difference, whether it was anticipated or unexpected, what you did to mitigate it if it was unfavorable, and how it affects forward pricing for the following year.

Significant usually means more than 2-3% variance or any variance that materially affected contract costs. Don’t just say “costs were higher than expected.” Explain specifically which cost categories drove the variance and why.

March: Conduct Your Pre-Submission Review

March is your quality control month. This is when you review your entire submission as if you were the auditor looking for problems.

Run Internal Consistency Checks

Numbers from your ICE submission need to tie to your financial statements, payroll reports, tax returns, and general ledger. DCAA will verify these ties, and unexplained differences delay audits while they investigate.

Check that your total costs per the ICE submission match your income statement, your direct labor per the ICE matches your payroll registers for direct employees, your indirect pools match the relevant income statement categories, and your revenue matches your billing records and receivables.

If you find discrepancies, track them down. Sometimes they’re legitimate timing differences or classification differences. Sometimes, there are errors that need correction. Either way, you need to understand and document them before submission.

Review for Common Audit Findings

The DCAA publishes common audit findings in its annual reports. Learn from others’ mistakes. Common issues include:

• Unallowable costs not correctly identified and excluded
• Inconsistent allocation methodologies
• Inadequate timekeeping documentation
• Unsupported indirect cost pool amounts
• Changes in accounting practices were not disclosed or adjusted

Walk through your submission, specifically looking for these issues. If you find them, fix them now. If you can’t fix them, at least prepare clear explanations of the circumstances and what corrective actions you’ve implemented.

Test Your Supporting Documentation

Pick several significant costs from each indirect pool and pull the supporting documentation as if you were responding to an audit request. Can you quickly locate the documentation? Is it clear and complete? Does it clearly support the cost amount and allocation?

If you struggle to find support or if the documentation is ambiguous, DCAA will struggle too. When auditors struggle, they start questioning everything, which extends audit timelines and increases the risk of questioned costs.

The Year-Round Habits That Make January Easier

Contractors who breeze through incurred cost audits don’t do it through heroic effort in January through March. They do it through consistent practices all year that make year-end preparation straightforward.

Reconcile accounts monthly rather than letting twelve months of issues pile up at year-end. The Small Business Administration recommends monthly reconciliations as a basic financial control for any business, and it’s essential for government contractors.

Review indirect rates quarterly to assess whether your actuals align with your projections. If significant variances are developing, you can investigate their causes in real time rather than trying to remember what happened months earlier.

Maintain organized filing systems for vendor invoices, contracts, and other supporting documentation. When everything is filed systematically as it occurs, you’re not searching through piles of paper in March.

Document significant decisions when you make them. If you had to make a judgment call about cost allocability or allowability, write down your reasoning at the time. Your memory of why you made a decision will be much clearer in the moment than six months later when DCAA asks about it.

Working With a Government Contracts CPA

Many contractors try to handle incurred cost submissions themselves to save money. That’s penny-wise and pound-foolish if it results in questioned costs, extended audits, or billing suspensions.

A Government Contracts accounting firm specializing in DCAA audits offers several advantages. They know what DCAA is looking for and how to present information in a way that satisfies auditors. These firms can spot potential issues before submission and help you address them proactively. They understand FAR and CAS requirements and can ensure your costs and methodologies comply. Additionally, they can represent you during the audit, respond to information requests, and negotiate questioned costs.

The cost of professional assistance is far less than the cost of questioned costs or suspended billing while issues are resolved. Most contractors who’ve been through a difficult audit realize they should have invested in expert help from the beginning.

The Bottom Line

Getting DCAA audit-ready isn’t something you do in the week before submission. It’s a systematic process that starts with a thorough year-end close in January, continues through documentation organization in February, and concludes with quality control review in March.

The contractors who consistently receive clean audit opinions and timely final rate determinations are those who treat incurred cost submissions as year-round discipline, not a springtime crisis. They maintain compliant systems all year, conduct regular self-reviews, and prepare systematically rather than reactively.

If your approach to incurred cost submissions has been to hope for the best and deal with problems as they arise, this year is the time to change that pattern. Use this checklist to build the habits and systems that make audit readiness automatic rather than stressful.
