Limitations on Subcontracting and the Similarly Situated Rule
A set-aside contract limits how much of the money the government pays a prime can flow onward to firms that are not in the same program. The ceiling changes with the type of work, and a subcontractor of the same status is not counted against it at all.
The rule in short
On a set-aside or socioeconomic program contract, a prime may pay no more than fifty percent of the amount the government pays it to firms that are not similarly situated for services or supplies, eighty-five percent for general construction, and seventy-five percent for special trade construction. Cost of materials is excluded outside services. Amounts paid to a similarly situated first-tier subcontractor are excluded to the extent that subcontractor performs with its own employees.
The limitation is a ceiling on outflow, not a floor on effort. A prime on a set-aside contract agrees that it will not pay more than a stated share of the amount the government pays it to firms that are not similarly situated. Everything else follows from that framing: the denominator is the contract amount received, and the numerator is what leaves the building.
The percentages, by type of work
For services other than construction, no more than fifty percent of the amount paid by the government may go to firms that are not similarly situated. For supplies other than from a nonmanufacturer, the same fifty percent applies, and the cost of materials is excluded from the calculation entirely. For general construction the ceiling is eighty-five percent, and for special trade contractors seventy-five percent, with materials excluded in both.
Only one ceiling applies to any contract. Where a requirement mixes services, supplies and construction, the contracting officer assigns a single industry code, and that assignment determines both which limitation applies and which portion of the award amount it is measured against. The portions falling outside the assigned category drop out of the calculation rather than being blended into it.
Subcontracting without spending the allowance
Amounts paid to a similarly situated entity are not treated as subcontracted at all. A similarly situated entity is a first-tier subcontractor holding the same program status that qualified the prime, and small under the code assigned to that subcontract. The exclusion is what makes teaming viable, because it lets a small prime bring in capacity without consuming its ceiling.
Two conditions limit it. The exclusion applies only to the extent the similarly situated subcontractor performs the work with its own employees; anything that subcontractor passes further down counts against the prime's ceiling as though the prime had paid it directly. And the status must persist. Once the subcontractor ceases to qualify as small, or loses the relevant program status, its work stops counting from that point.
The supplies and construction ceilings exclude the cost of materials, and the services ceiling does not. Services contracts instead exclude certain other direct costs that are not the principal purpose of the acquisition and that small businesses do not supply, such as airline travel, cloud computing services and mass media purchases. Firms that carry the materials exclusion across from a construction contract to a services contract routinely calculate their position several percentage points better than it actually is.
| Category | Ceiling on payments outside the program | Materials excluded | Other exclusions | Common miscalculation |
|---|---|---|---|---|
| Services other than construction | Fifty percent | No | Defined other direct costs not central to the acquisition | Deducting materials that are not deductible |
| Supplies, prime is the manufacturer | Fifty percent | Yes | None beyond materials | Counting an affiliate as in-house labor |
| Supplies from a nonmanufacturer | Must supply a domestic small business manufacturer's product | Not applicable | Class or contract-specific waivers | Assuming a waiver applies without confirming it |
| General construction | Eighty-five percent | Yes | None beyond materials | Applying the special trade figure |
| Special trade construction | Seventy-five percent | Yes | None beyond materials | Applying the general construction figure |
Supplying an item the prime does not make
A small business that does not manufacture the item supplies it under a separate rule. It must furnish the product of a domestic small business manufacturer or processor unless a waiver has been granted. Waivers come in two forms: class waivers issued where no small business manufacturer supplies the class of item, and contract-specific waivers issued for a particular acquisition.
On a multiple-item procurement, the calculation combines the value of items supplied by domestic small business manufacturers with the value of items covered by a waiver, and that combined value must reach at least half the value of the contract. A prime may also act as manufacturer for some items and nonmanufacturer for others in the same award.
The period over which the ceiling is tested
Compliance is generally measured over the base term and then over each option period separately, so a shortfall in the base cannot be repaired by overperformance later. For a multi-agency contract where several agencies place orders, compliance is measured over the period of performance of each order, and the ordering officer reports a failure back to the officer administering the underlying contract.
That structure has a planning consequence. A prime that front-loads outside subcontracting into the base year, intending to bring work in-house once it has hired, is out of compliance for the base year regardless of what happens afterward. Tracking has to run against the applicable measurement period rather than against the life of the contract.
The rules that sit next to this one
The limitation and the affiliation rules point in opposite directions and have to be read together. A subcontract to a similarly situated entity is excluded from the ostensible subcontractor analysis, but a subcontract to anyone else that carries the primary and vital requirements can produce affiliation and cost the prime its eligibility, which is examined in size protests and the affiliation rules.
The clause reaches the contract through the set-aside provisions applied at solicitation, so a firm objecting to how a requirement was structured has to raise it before offers close under the timing described in the bid protest framework. Whether the acquisition was conducted by a method that even permits teaming discussions is answered by the comparison of procurement methods, and a certification made at award without capability to honor it raises the questions covered in responsiveness and responsibility.
Points to carry away
- The ceiling is measured against the amount the government pays the prime, not against total costs.
- Services and supplies carry a fifty percent ceiling on payments to firms that are not similarly situated.
- General construction carries eighty-five percent and special trade construction seventy-five percent.
- Cost of materials is excluded from the calculation except in the services category.
- A similarly situated subcontractor's work counts as the prime's only where its own employees perform it.
- The single applicable ceiling is fixed by the code the contracting officer assigns to the acquisition.
Questions readers ask
What makes a subcontractor similarly situated?
It must be a first-tier subcontractor holding the same small business program status that qualified the prime for the award, and it must be small under the code the prime assigns to that subcontract. A service-disabled veteran-owned firm subcontracting to a woman-owned firm is not similarly situated, because the statuses differ even though both are small. Status is also continuous rather than fixed at award: a subcontractor that outgrows the size standard stops counting from that point forward.
Does work performed by an affiliate count as the prime's own?
Only if the affiliate is itself a similarly situated first-tier subcontractor. Common ownership does not merge the two for this purpose, and treating an affiliate's labor as in-house work is a frequent basis for a finding of noncompliance. The related risk is worse: an arrangement in which an affiliate or a large subcontractor performs the primary and vital requirements can support a finding of affiliation, which puts the prime's eligibility for the award itself in question.
What are the consequences of exceeding the ceiling?
The statute provides a civil penalty measured as the greater of a fixed statutory sum or the amount expended in excess of the permitted level, and a knowing violation supports false claims exposure because the prime certified compliance. Beyond money, the practical consequences are suspension or debarment proceedings, loss of the contract, and a record that follows the firm into every future set-aside competition. The certification is made at award and repeated by performance.

The Debriefing and the Clock It Starts
An offeror excluded before award, or notified of an award in a negotiated procurement, may obtain a debriefing by written request made within three days of the notice. A required debriefing must disclose the evaluation of the offeror's own proposal, the awardee's evaluated price and technical rating, any overall ranking and the rationale for award. It may not disclose point-by-point comparisons. The debriefing date controls both the protest deadline and the window for the automatic suspension.
Sealed Bidding and Negotiated Procurement Compared
Sealed bidding is required where time permits, award will be made on price and price-related factors, discussions are unnecessary, and more than one bid is expected. Bids are opened publicly and award goes to the responsible bidder whose responsive bid is most advantageous considering price alone. Negotiated procurement evaluates proposals against stated factors, permits a competitive range and discussions, and allows an award to other than the lowest price where the solicitation says so.
The Settlement Proposal After a Contract Is Ended Early
On a convenience termination the contractor stops work, terminates subcontracts, protects and disposes of property, and submits a settlement proposal within one year of the effective date unless the period is extended in writing. Recoverable amounts include preparations and work done, initial costs, settlement expenses, subcontractor settlements, and reasonable profit on work performed. Anticipatory profit is not recoverable, and a loss contract carries no profit.
