Subcontractor Management DCAA Rules for Prime Contractors

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 Does DCAA Hold Prime Contractors Responsible for Subcontractor Costs?

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.

When Does a Prime Contractor Need Contracting Officer Consent to Award a Subcontract?

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 consent threshold is not a flat dollar amount. FAR 44.201-1 and FAR 52.244-2 base the trigger on the simplified acquisition threshold (currently $350,000, raised from $250,000 effective 1 October 2025) [90 FR 41872] or 5% of the total estimated contract cost, whichever is greater (for DoD, Coast Guard, and NASA contracts). For contracts with other federal civilian agencies, FAR 44.201-1(b)(2)(ii) uses an “either/or” formulation: consent applies when the subcontract meets either the simplified acquisition threshold or the 5% figure, not only when both are exceeded. The specific language in your contract’s FAR 52.244-2 clause governs.

For primes without an approved purchasing system, consent is required for all cost-reimbursement, time-and-materials, and labor-hour subcontracts, as well as fixed-price subcontracts exceeding the applicable threshold. One gate decides whether any of this reaches you, and most summaries leave it out. FAR 52.244-2(b) says that when the clause sits in a fixed-price type prime contract, consent is required only on unpriced contract actions, including unpriced modifications and unpriced delivery orders. A prime holding firm-fixed-price work with priced orders reads the whole consent scheme and still owes nothing under it.

The specific threshold in your situation depends on your agency, your contract type, and whether you hold an approved purchasing system. Read FAR 52.244-2 in your specific prime contract for the exact requirements that apply to you.

Here is what most primes overlook: even below any dollar threshold, 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 Contract Line Item Number (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 [48 CFR 9904.418]. 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. The flow-down is conditional, not automatic. Paragraph (g)(1) reaches subcontracts that exceed the simplified acquisition threshold on the date of award and are cost-reimbursement, incentive, time-and-materials, labor-hour or price-redeterminable, or require certified cost or pricing data, or require the subcontractor to furnish the reports described in paragraph (e). A fixed-price subcontract outside those categories does not pick the clause up, and DCAA gains no direct examination right into that subcontractor’s books.
• FAR 52.222-26 (Equal Opportunity): the $10,000 figure is not a subcontract threshold. FAR 52.222-26(b)(1) applies the clause to a contractor holding nonexempt federal contracts and subcontracts with an aggregate value over $10,000 in any 12-month period, and paragraph (c)(11) then flows the terms down to every subcontract or purchase order not exempted by Secretary of Labor rules. The codified page is not the whole picture here. Executive Order 11246, the authority the clause runs on, was revoked in January 2025, and the Department of Labor has proposed rescinding its implementing regulations at 41 CFR part 60 [90 FR 28472]. That rescission is still a proposed rule, and the FAR clause remains prescribed at 22.810(e) as of FAC 2026-01. Flow it down, and ask your contracting officer about an agency class deviation before you rely on it either way.
• FAR 52.222-50 (Combating Trafficking in Persons): required in all subcontracts.
• FAR 52.203-13 (Contractor Code of Business Ethics and Conduct): flowed down by FAR 52.203-13(d)(1) to subcontracts that exceed the FAR 3.1004(a) threshold of $7.5 million on the date of subcontract award and have a performance period of more than 120 days. The prime-contract test at FAR 3.1004(a) reads “120 days or more”. The subcontract test reads “more than 120 days”. A subcontract running exactly 120 days sits inside the prime test and outside the flow-down test.
• FAR 52.219-8 (Utilization of Small Business Concerns): the current clause carries no flow-down paragraph at all. The January 2025 version runs from paragraph (a) to paragraph (e)(5) and stops. It contains no “include the substance of this clause” sentence, no $750,000 or $1.5 million construction figure, and no subcontractor plan threshold. FAR 19.708(a) prescribes it for solicitations and contracts above the simplified acquisition threshold and says nothing about subcontracts. If your subcontract template flows 52.219-8 down because an older checklist told you to, the duty you are creating is contractual, not regulatory. The separate subcontracting plan duty sits in FAR 52.219-9, prescribed at 19.708(b)(1) above $900,000, or $2 million for construction of a public facility.
• 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. The withhold itself is not in that clause. It sits in DFARS 252.242-7005, Contractor Business Systems, and paragraph (a) of that clause limits it to covered contracts subject to the Cost Accounting Standards. A contractor with no CAS-covered contract holds a disapproved purchasing system and still faces no withhold under this clause.

CAS Coverage for Subcontractors

Cost Accounting Standards apply to subcontractors independently based on the subcontractor’s own contract volume. A CAS-covered subcontract (one of $2.5 million or more, not otherwise exempt) generally falls under modified CAS coverage. The Disclosure Statement (DS-1) requirement and full CAS coverage are triggered at $50 million: a single CAS-covered subcontract of $50 million or more, or $50 million or more in net CAS-covered awards in the prior cost accounting period. These thresholds are widely cited in practice; confirm current figures at 48 CFR 9903.201-2 before relying on them for a specific subcontract decision.

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 [48 CFR 9903.201-1], 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.

Where DFARS 252.242-7005 is also in the contract, a material weakness finding lets the contracting officer withhold 5 percent of amounts due from progress payments and performance-based payments, and direct the same 5 percent withholding on interim cost vouchers [252.242-7005(e)(1)]. There is a documented way down. An acceptable corrective action plan submitted within 45 days, which the contracting officer agrees you are effectively implementing, cuts the withholding to 2 percent [(e)(2)]. Withholding is capped at 5 percent for weaknesses in any single business system and 10 percent across multiple systems [(e)(3)(i)].

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, because FAR 31.203(c) requires the base to allocate the grouping on the basis of the benefits accruing to intermediate and final cost objectives [FAR 31.203(c)].

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 [48 CFR 9904.418]. One limit applies to both. FAR 31.203(d) says that once a base has been accepted, the contractor shall not fragment it by removing individual elements. Design the base that way at the outset and disclose it. Carving subcontractor costs out of a base the government has already accepted is a different act, and it is a change in cost accounting practice rather than a refinement.

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 trigger under FAR 44.201-1 is not a flat dollar amount. For primes without an approved purchasing system, consent applies to all cost-type subcontracts and to fixed-price subcontracts exceeding the simplified acquisition threshold ($350,000) or 5% of estimated contract cost. Read the FAR 52.244-2 clause in your specific contract. 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.
