Subcontractor Management: Accounting and Compliance Requirements DCAA Checks

Your DCAA auditor pulls Schedule J from your incurred cost submission and points to a $1.2 million subcontract line item. “Show me the contracting officer’s consent for this subcontract,” she says. You open the contract file. The consent letter is not there. The subcontract was awarded nine months ago, three task orders have already been billed, and your subcontractor has invoiced $840,000 against the contract. The auditor makes a note. Every dollar billed under that subcontract is now in question.

This scenario plays out more often than most prime contractors expect. Subcontractor management DCAA requirements sit at the intersection of cost accounting, procurement compliance, and contract administration. DCAA does not audit your subcontractor directly in most cases. DCAA audits your system for managing subcontractors: how you select them, how you get consent, how you monitor their costs, and how you flow down federal requirements.

Prime contractors who treat subcontract management as a procurement function miss half the picture. The accounting obligations are equally demanding, and DCAA tests them separately from your purchasing system review.

Why Subcontractor Management DCAA Reviews Target Primes

DCAA holds the prime contractor accountable for all costs billed to the government, including subcontractor costs. When a subcontractor’s costs are questioned, the questioned cost appears on the prime’s audit report, not the subcontractor’s. The prime bears the financial risk.

FAR Part 44 establishes the framework for subcontract management on government contracts [FAR Part 44]. The regulation assigns primes two distinct obligations: obtaining consent from the contracting officer before awarding certain subcontracts, and maintaining an approved purchasing system for managing subcontract activity. DCAA evaluates both.

The stakes are concrete. A $5 million IT services prime with $2 million in subcontractor costs has 40% of its contract value flowing through entities it does not directly control. If the subcontractor’s timekeeping fails a DCAA floor check, or if the subcontractor’s indirect rates include unallowable costs, the prime’s incurred cost submission reflects those deficiencies. DCAA does not care that the error originated with the subcontractor. The prime signed the contract. The prime approved the invoice. The prime billed the government.

Consent to Subcontract: The $750,000 Threshold and FAR 44.201-2

Contracting officer consent is required before a prime awards certain subcontracts. FAR 44.201-1 states that consent is required when the prime contract includes the clause at FAR 52.244-2 (Subcontracts) and the subcontract meets specific criteria. FAR 44.201-2 defines the contracting officer’s evaluation standards for granting or withholding consent.

The $750,000 advance notification threshold applies under FAR 44.201-1(a)(2). Primes must notify the contracting officer before awarding any cost-reimbursement, time-and-materials, or labor-hour subcontract exceeding $750,000, or any fixed-price subcontract exceeding $750,000 when the prime does not have an approved purchasing system. The contracting officer then decides whether formal consent is needed.

Here is what most primes overlook: even below $750,000, the contracting officer retains authority to require consent for specific subcontracts. The contract clause at FAR 52.244-2 allows the contracting officer to list categories of subcontracts requiring consent regardless of dollar value. Read your contract’s Section H or Section I for these specific requirements.

Missing consent is not a technicality. DCAA flags the entire subcontract cost as potentially unallowable when consent documentation is absent. The contracting officer decides the final disposition, but the audit finding creates months of administrative work to resolve, and retroactive consent is not guaranteed.

Tracking and Allocating Subcontractor Costs

Subcontractor costs require the same traceability as any direct cost charged to a government contract. Every subcontractor invoice must tie to a specific contract, a specific CLIN or task order, and a specific period of performance. The prime’s accounting system must track subcontractor costs separately from other direct costs and from the prime’s own labor and materials.

The allocation question matters most for subcontractor costs hitting indirect pools. If a subcontractor provides services benefiting multiple contracts (IT support, facility maintenance, security), those costs belong in an indirect cost pool with an appropriate allocation base. CAS 418 governs how direct and indirect costs are allocated, and subcontractor costs follow the same rules [FAR 30.201-4]. Misclassifying an indirect subcontract cost as a direct charge to one contract is a CAS 402 consistency violation.

Three cost-tracking requirements trip up primes regularly:

1. Invoice verification against subcontract terms. The prime must verify each subcontractor invoice against the subcontract’s rate schedule, labor categories, and authorized scope. Paying a subcontractor invoice without verification and then billing the government is a questioned cost waiting to happen.
2. Subcontractor cost segregation in the general ledger. Your chart of accounts needs separate accounts for subcontractor costs by contract. Lumping subcontractor costs with other direct costs (materials, travel, ODCs) makes audit traceability difficult and raises red flags during incurred cost reviews.
3. Material handling rate applicability. Some contractors apply a material handling rate to subcontractor costs. DCAA scrutinizes this practice. If your material handling pool includes costs unrelated to subcontract administration (warehouse operations, inventory management), applying that rate to subcontractor invoices overstates the allowable cost. Separate the functions or justify the allocation base.

Flow-Down Clauses: What Primes Must Pass to Subcontractors

Federal Acquisition Regulation clauses do not automatically apply to subcontractors. The prime must actively flow down required clauses by including them in the subcontract agreement. Missing flow-down clauses create compliance gaps DCAA and the contracting officer review during purchasing system audits.

FAR 52.244-6 (Subcontracts for Commercial Products and Commercial Services) lists mandatory flow-down clauses for commercial subcontracts. For non-commercial subcontracts, each individual FAR clause specifies whether it applies to subcontracts. The prime must review every clause in its prime contract and determine which ones require flow-down.

Critical flow-down clauses for accounting and compliance purposes include:

• FAR 52.215-2 (Audit and Records): gives the government and DCAA access to the subcontractor’s books. Without this clause, DCAA has no right to audit the subcontractor’s costs directly.
• FAR 52.222-26 (Equal Opportunity): required in subcontracts over $10,000.
• FAR 52.222-50 (Combating Trafficking in Persons): required in all subcontracts.
• FAR 52.203-13 (Contractor Code of Business Ethics): required in subcontracts over $6 million with a performance period exceeding 120 days.
• FAR 52.219-8 (Utilization of Small Business Concerns): required in subcontracts over $750,000 ($1.5 million for construction).
• FAR 52.216-7 (Allowable Cost and Payment): if the subcontract is cost-reimbursement, this clause triggers the subcontractor’s own ICS obligation.

A flow-down gap does not make the subcontract cost automatically unallowable. But it creates a compliance deficiency the contracting officer documents. Repeated flow-down failures contribute to a purchasing system disapproval under DFARS 252.244-7001, which triggers a 5% payment withhold on all contracts.

CAS Coverage for Subcontractors

Cost Accounting Standards apply to subcontractors independently based on the subcontractor’s own contract volume. A subcontractor with aggregate CAS-covered subcontract awards exceeding $7.5 million in its prior cost accounting period triggers modified CAS coverage and must file a Disclosure Statement (DS-1). A single CAS-covered subcontract exceeding $50 million triggers full CAS coverage [FAR 30.201-4].

The prime’s responsibility: verify the subcontractor’s CAS coverage status before subcontract award. If the subcontractor requires a Disclosure Statement and has not filed one, the subcontract award creates a compliance deficiency for the prime. DCAA checks this during purchasing system reviews.

Small business subcontractors are generally CAS-exempt [FAR 30.201-1], as are subcontracts awarded through sealed bidding procedures. Primes should document the CAS exemption basis in the subcontract file. A one-paragraph memo stating the exemption reason and regulatory cite satisfies this requirement. Leaving the file silent on CAS coverage invites auditor questions during the purchasing system review.

DCAA Audit Focus Areas for Subcontract Management

DCAA examines subcontract management through two audit programs: the purchasing system review and the incurred cost audit. Each program tests different aspects of the prime’s subcontract management practices.

During a purchasing system review, DCAA evaluates whether the prime’s procurement policies and procedures meet the criteria in DFARS 252.244-7001. The auditor selects a sample of subcontract files and tests for documented source selection rationale, price reasonableness determinations, consent documentation, and flow-down clause inclusion. A system disapproval triggers a 5% withhold on covered contract payments until the deficiencies are corrected.

During an incurred cost audit, DCAA tests subcontractor costs for allowability and allocability. The auditor verifies:

• Subcontractor invoices match the subcontract terms (rates, labor categories, authorized scope)
• The prime reviewed and approved each invoice before billing the government
• Subcontractor costs are charged to the correct contract and CLIN
• Consent was obtained for subcontracts requiring consent
• Subcontractor costs in the G&A base are correctly included or excluded per the contractor’s disclosed practices

Here is what most primes miss about the G&A base question. If your disclosed practice includes subcontractor costs in your total cost input base for G&A allocation, every subcontractor dollar absorbs G&A. On a contract with $2 million in subcontractor costs and a 15% G&A rate, the G&A applied to subcontractor costs alone is $300,000. DCAA tests whether your G&A pool actually provides services benefiting those subcontractor costs. If the subcontractor operates independently with minimal prime oversight, applying full G&A to those costs is difficult to defend [FAR 31.203].

Some primes create a separate subcontractor cost base with a lower G&A rate applied. Others exclude subcontractor costs from the G&A base entirely and charge only direct administrative costs for subcontract management. Either approach works if it reflects the actual benefit relationship and is consistently applied [CAS 418].

Frequently Asked Questions

Key Takeaways

• The prime pays for the subcontractor’s mistakes. DCAA questions subcontractor costs on the prime’s audit report. Building a subcontract management system is not optional; it protects your billable costs.
• Consent before award, not after. The $750,000 notification threshold under FAR 44.201-1 applies to cost-type subcontracts and fixed-price subcontracts without an approved purchasing system. Retroactive consent is not guaranteed.
• Flow-down clauses require active management. Review every prime contract clause for subcontract applicability. A missing FAR 52.215-2 audit clause strips DCAA’s access to the subcontractor’s books entirely.
• G&A treatment of subcontractor costs is an audit target. Applying a 15% G&A rate to $2 million in subcontractor costs generates $300,000 in charges DCAA will test against the actual benefit relationship.
• Document CAS coverage status for every subcontractor. A one-paragraph exemption memo in the subcontract file prevents purchasing system review findings.
