Government Contract Compliance: Essential Guide for Contractors
Master government contract compliance with proven strategies. Learn key requirements, avoid costly violations, and build systems that protect your business.
When Compliance Fails: The Stakes Are Real
In 2022, a Virginia-based IT services firm lost a $4.2 million GSA task order mid-performance after a DCAA audit revealed unallocated indirect costs and missing timekeeping records spanning eight months. The contracting officer issued a cure notice, the contractor could not cure in time, and the contract was terminated for default. That termination went into CPARS. Every subsequent proposal the firm submitted had to explain it. Two years later, they were still losing evaluations because of it.
That scenario is not unusual. Government contract compliance is not a back-office function. It is a business continuity issue. This guide covers the specific regulatory areas, system requirements, and audit preparation steps that keep contractors performing, paid, and positioned to win again.
The Regulatory Framework You Are Actually Operating Under
Federal contractors do not answer to a single rulebook. Compliance obligations stack depending on contract type, dollar threshold, agency, and socioeconomic program participation. Understanding which rules apply to your specific situation is the first step.
Federal Acquisition Regulation (FAR) Baseline
The FAR governs virtually every federal procurement. Key compliance-heavy clauses include FAR 52.215-2 (audit and records access), FAR 52.222-26 (equal opportunity), FAR 52.203-13 (contractor code of business ethics), and FAR 52.244-6 (subcontracting for commercial items). These clauses are not optional. They are incorporated by reference into your contract whether or not you read them during proposal.
Contracts above $5.5 million (with a performance period exceeding 120 days) typically trigger the mandatory disclosure requirement under FAR 52.203-13, meaning you must report credible evidence of fraud, conflict of interest violations, or significant overpayments. Failure to disclose can itself constitute a violation under the False Claims Act.
Agency-Specific Supplements
Defense contracts add the DFARS (Defense Federal Acquisition Regulation Supplement). A DFARS 252.204-7012 clause, for example, requires specific cybersecurity incident reporting within 72 hours and mandates NIST SP 800-171 compliance for covered defense information. Civilian agencies have their own supplements: HHSAR for HHS, EPAAR for EPA, DOLAR for DOL. If you are working across multiple agencies on an IDIQ vehicle like GSA MAS or a GWAC, you may be managing multiple supplement requirements simultaneously.
Financial and Accounting Compliance: What DCAA Actually Looks For
The Defense Contract Audit Agency conducts pre-award accounting system surveys, incurred cost audits, and floor checks. A DCAA-adequate accounting system is not just good practice for defense contractors. Many civilian agencies and inspectors general use the same adequacy criteria as a benchmark.
The 18 DCAA Adequacy Criteria
DCAA's SF 1408 pre-award survey evaluates 18 specific criteria, including whether your system identifies and accumulates costs by contract, whether it segregates unallowable costs (per FAR Part 31), and whether it produces accurate and timely financial data. Common failure points include:
- Commingling of direct and indirect costs in the same account
- No written accounting policies and procedures manual
- Timekeeping systems that allow after-the-fact editing without audit trails
- Failure to exclude unallowable costs (entertainment, lobbying, certain IR&D) from billing
If your accounting system is found inadequate during a pre-award survey, the contracting officer can withhold award. Fix this before you win a cost-reimbursable contract, not after.
Incurred Cost Submissions
Contractors with cost-reimbursable contracts must submit an Incurred Cost Submission (ICS) to DCAA within six months of fiscal year end. The ICS reconciles actual indirect rates against the provisional billing rates used during the year. Late or inaccurate submissions trigger audits and can result in withheld payments. Use the DCAA's ICE (Incurred Cost Electronically) model as your template. It is publicly available and maps directly to what auditors expect.
Labor Standards: Service Contract Act and Davis-Bacon Act
If your contract involves services performed by non-exempt workers, the McNamara-O'Hara Service Contract Act (SCA) almost certainly applies. SCA requires you to pay wages and fringe benefits at least equal to the wage determination (WD) incorporated into your contract. Wage determinations are locality-specific and occupation-specific. A help desk technician in San Antonio has a different WD than the same role in Washington, DC.
Common SCA violations include misclassifying workers under the wrong Standard Occupational Classification (SOC) code, failing to update wages when a contract is extended and a new WD is issued, and not providing the required health and welfare fringe benefit at the current DOL-published rate (updated annually; currently several dollars per hour) or an equivalent benefit. The Department of Labor Wage and Hour Division investigates SCA complaints and can assess back wages plus debarment for willful violations.
Davis-Bacon Act applies to construction contracts exceeding $2,000. If your firm does any construction, alteration, or repair on federal or federally assisted projects, you need a separate compliance workflow for prevailing wage tracking on those contracts.
Building a Compliance Management System That Holds Up
The Compliance Calendar
Every contract generates a set of recurring obligations with hard deadlines. Map them at contract award, not when a deadline is approaching. A basic compliance calendar for a single cost-plus contract might include: monthly invoicing under FAR 52.232-25, subcontracting reports submitted via the electronic Subcontracting Reporting System (eSRS), which replaced the paper SF-294 and SF-295 forms if you have a subcontracting plan, semi-annual small business utilization reports, annual representations and certifications renewal in SAM.gov, and the ICS due six months after fiscal year end. Multiply this across five or ten active contracts and the calendar becomes a critical operational tool.
Document Retention Requirements
FAR 4.703 requires contractors to retain most contract records for three years after final payment. Cost or pricing data records must be retained for three years after agreement on final indirect cost rates. Employee timekeeping records under the SCA must be kept for three years. Build your document management system around these retention schedules. Organize by contract number, then by document type. When a DCAA auditor arrives and asks for all labor distribution records for Contract No. W912BV-22-C-0041 from January through June 2023, you need to produce them in hours, not days.
Subcontractor Flow-Down Requirements
As prime contractor, you are responsible for your subcontractors' compliance. FAR 52.244-6 requires you to flow down certain clauses to commercial item subcontractors. For non-commercial subcontracts, the flow-down requirements are more extensive. Your subcontract agreements must include applicable FAR, DFARS, and agency supplement clauses. Beyond the paperwork, you need a monitoring process: collect subcontractor certified payrolls if SCA applies to their scope, review their invoices for unallowable cost categories, and document your oversight activities. If a subcontractor commits a False Claims Act violation on your contract, you can be held jointly liable.
Cybersecurity Compliance: An Increasingly Non-Negotiable Requirement
CMMC (Cybersecurity Maturity Model Certification) is now being phased into DoD contracts. CMMC Level 2 requires a third-party assessment against all 110 NIST SP 800-171 controls for contracts involving Controlled Unclassified Information (CUI). For civilian agencies, FISMA compliance and FedRAMP authorization for cloud services are the parallel requirements. If you handle CUI, Protected Health Information (PHI under HIPAA), or payment card data (PCI DSS scope), you need documented security plans, incident response procedures, and in some cases third-party assessments before you can perform.
Cybersecurity compliance is no longer a large-contractor concern. A 15-person firm with a single DoD task order involving technical drawings may be handling CUI and subject to DFARS 252.204-7012 and CMMC requirements. Assess your CUI exposure early in the capture process, not after contract award.
Preparing for Audits Before Auditors Arrive
DCAA floor checks happen without advance notice. An auditor may walk into your office and ask to interview employees about their timekeeping practices on the spot. Employees should know: always record time daily, never let a supervisor fill in their timesheet, and charge time to the correct contract or indirect account. These are not suggestions. They are audit survival basics.
For scheduled audits, prepare a document index in advance. List every document category the auditor is likely to request, where it is stored, and who is responsible for producing it. Designate a single point of contact to manage auditor communications. Do not let auditors wander through your systems unescorted or interview staff without your compliance lead present.
Using Technology to Reduce Compliance Risk
Compliance tracking tools, proposal automation platforms, and contract management systems can reduce the manual burden significantly. Tools like Winrove (available at winrove.com, plans from $49/mo), a product of IT Custom Solution LLC, help capture managers track solicitation requirements and compliance obligations from RFP through award. The key is integrating whatever tools you use with your accounting system and document management workflow so compliance data is not siloed.
The Bottom Line
Government contract compliance is a system, not an event. Build your accounting structure before you win cost-reimbursable work. Map your compliance calendar at contract award. Flow down clauses to subcontractors in writing and verify their adherence. Train your timekeeping staff on government-specific requirements. And treat every audit as a process you manage, not a surprise you survive. Contractors who treat compliance as operational infrastructure win more, perform better, and protect the past performance record that drives future revenue.
