Limitations on Subcontracting

Limitations on subcontracting are regulations in 13 CFR 125.6 and FAR 52.219-14 that restrict how much work a small business prime contractor on a set-aside contract may subcontract to firms that are not similarly situated, preventing small businesses from winning set-aside contracts and then subcontracting the substantive work to large companies or ineligible firms.

What are Limitations on Subcontracting?

The core requirement is that a small business prime on a set-aside contract must itself perform the applicable minimum percentage of the contract's cost or work. "Similarly situated" subcontractors, those that hold the same small business certification as the prime (e.g., both SDVOSB-certified), count toward the prime's own performance percentage. Work subcontracted to large businesses or small businesses without the required certification does not count.

The minimum performance thresholds vary by contract type. For service contracts, the prime must perform at least 50% of the cost of the contract incurred for personnel. For general construction, the prime must perform at least 15% of the cost with its own employees. For specialty trade construction, the prime performs at least 25% with its own employees. For supply contracts, the prime must perform at least 50% of the cost of manufacturing the supplies (or comply with the Nonmanufacturer Rule if it is a reseller).

Violations are treated as performance failures and can result in suspension, debarment, and False Claims Act liability. Contracting officers monitor compliance through invoices, payroll records, and subcontract data. Firms that structure their contracts to technically meet the percentage while effectively subcontracting the core mission capability, a practice sometimes called "brokering", risk enforcement action even if the arithmetic appears to comply.

Why Limitations on Subcontracting Matter for Government Contractors

These rules define the boundary between a legitimate small business prime and a conduit that exists only to capture set-aside eligibility while a large business performs the real work. Understanding the thresholds is essential for: structuring teaming arrangements and joint ventures to ensure the small business partner genuinely performs; pricing proposals accurately by accounting for the work the prime must retain; and avoiding compliance risk when building a subcontractor team for large set-aside contracts. For similarly situated subcontractors, understanding that their work counts toward the prime's performance threshold makes them more valuable teaming partners than non-certified counterparts.

Example

A WOSB-certified IT services firm wins a $6M WOSB set-aside service contract. It must perform at least 50% of the personnel cost, approximately $3M, with its own employees. It may subcontract the remaining $3M to other firms. It subcontracts $1.5M to another WOSB-certified IT firm (similarly situated, so this counts toward the prime's own performance) and $1.5M to a non-certified small business. The prime's own direct employee costs plus the similarly situated subcontractor costs together exceed 50%, so the limitation is met.

Frequently Asked Questions

What does "similarly situated" mean for limitations on subcontracting?

A similarly situated entity is a subcontractor that holds the same socioeconomic certification as the prime contractor for the set-aside in question. If the prime is an SDVOSB on an SDVOSB set-aside, then SDVOSB-certified subcontractors are similarly situated. Their work counts toward the prime's performance requirement as though the prime itself performed it. This rule encourages teaming among firms within the same certification category.

Does this rule apply to task orders on IDIQ vehicles?

Yes. Limitations on subcontracting apply at the contract level, including individual task orders on IDIQ set-aside vehicles. A small business that holds a seat on an SDVOSB-reserved pool of an IDIQ must comply with the limitations on each task order it receives, not just at the master contract level. The contracting officer may require task-order-level certifications of compliance.

How are violations detected?

Contracting officers may require compliance certifications during contract performance. DCAA auditors reviewing contractor payroll and subcontract records can flag situations where subcontract costs substantially exceed the statutory limit. GAO and inspector general reviews of set-aside contracts periodically examine limitations on subcontracting compliance. Competitors who observe apparent violations may raise concerns directly with the contracting officer or OSDBU.

Do these rules apply differently in mentor-protege joint ventures?

In SBA-approved mentor-protege joint ventures, the protege (small business) must perform at least 40% of the work. This is a lower threshold than the standard 50% for service contracts, and it is measured across the joint venture as a whole rather than requiring the small business to perform 40% independently of the mentor's contribution. The joint venture's combined work split must be documented in the joint venture agreement and verified during contract performance.
