An agency that wins a federal small business set-aside for software work signs a promise most owners skim: the agency itself, or a similarly situated partner, will do at least half the work. Overflow capacity is how agencies usually stretch past their headcount, and on a set-aside it is also how they can break that promise. The penalty in the SBA's own rule is the greater of 500,000 dollars or the amount spent over the limit.
This post walks through what 13 CFR 125.6 says, who counts as a "similarly situated" subcontractor, a worked example with an offshore bench in it, and where the rule does not apply at all. It is general information, not legal advice. The contracting officer and your counsel decide how it applies to your award.
What is the SBA limitation on subcontracting?
It is a condition the SBA writes into set-aside awards. Under 13 CFR 125.6(a), as published in the eCFR on 1 October 2026, a small business concern must agree to it to be awarded a small business set-aside contract with a value greater than the simplified acquisition threshold, and the same section lists 8(a), service-disabled veteran-owned, veteran-owned, HUBZone, and women-owned set-asides too. For a services contract other than construction, section 125.6(a)(1) says the firm "will not pay more than 50% of the amount paid by the government to it to firms that are not similarly situated."
Two details change how an agency should read that sentence. First, the base is the amount the government pays you, not your cost and not the sticker price of the contract. Second, the limit counts what you pay out, so it applies to money flowing to subcontractors, not to hours or headcount.
Larger than the simplified acquisition threshold. Section 125.6(f)(1) says the limits do not apply to set-aside contracts above the micro-purchase threshold but at or below the simplified acquisition threshold. The Federal Acquisition Regulation, at 48 CFR 2.101 in the eCFR on 1 October 2026, sets that threshold at 350,000 dollars, with exceptions for contingency and similar acquisitions.
So an agency with a 200,000 dollar set-aside task order is outside the rule on the SBA's text, and one with a 450,000 dollar award is inside it. The contract itself may still carry its own terms, so read the clauses rather than relying on a threshold.
Who counts as a similarly situated subcontractor?
The definition in 13 CFR 125.1 is narrow. A similarly situated entity is "a subcontractor that has the same small business program status as the prime contractor." For a plain small business set-aside, that means a subcontractor that is itself a small business concern, and it must also be small for the NAICS code the prime assigned to the subcontract.
Section 125.6(c) adds the catch. Money paid to a similarly situated subcontractor is not counted against the limit only "to the extent the subcontractor performs the work with its own employees." Whatever that subcontractor passes down to someone else counts as subcontracted. Section 125.6(a)(1) repeats the point for the 50% cap: work a similarly situated subcontractor further subcontracts counts toward the amount that cannot be exceeded.
Two consequences for an agency's bench:
- A US small-business agency you subcontract to can help you, if its own staff do the work. If it hands your task to a third firm, that slice moves back onto your side of the ledger.
- An independent contractor is treated as a subcontract. Under section 125.6(f)(3), work by an independent contractor who is not treated as an employee for size purposes is considered subcontracted, and it counts toward your limit only where the contractor qualifies as a similarly situated entity.
Where does an offshore developer fall?
Almost certainly outside the protected group. The SBA's definition of a business concern in 13 CFR 121.105(a)(1), as published on 1 October 2026, describes a for-profit entity "with a place of business located in the United States," that either operates primarily within the United States or makes a significant contribution to the U.S. economy through taxes or use of American products, materials or labor. A bench of engineers abroad with no US place of business does not fit the first limb, and I would not build a bid on the argument that it fits the second without counsel's written view.
That is my reading of the two definitions together, not an SBA example, so confirm it with the contracting officer before you price. The practical rule is simpler: on a set-aside, assume payments to an offshore subcontractor count against your 50%.
A worked example
Picture a 14-person US agency that wins a 600,000 dollar small business set-aside to build a case-management system, assigned a services NAICS code, with a 12-month base term. The government will pay the agency 600,000 dollars over that term.
The agency may pay up to 300,000 dollars to firms that are not similarly situated. The other 300,000 dollars of the government's payments has to stay with the agency's own people or similarly situated partners doing the work with their own employees.
Now say the agency staffs overflow like this: a 220,000 dollar offshore pod, plus 130,000 dollars to a larger US firm that is not a small business for that NAICS code. That is 350,000 dollars paid to non-similarly-situated firms, which is 50,000 dollars over. Section 125.6(h) sets the fine as the greater of 500,000 dollars or the dollar amount spent over the permitted level. Here the 500,000 dollar floor is the number, ten times the overage. The arithmetic is mine, not an SBA example, and it ignores the exclusions described in the next section.
Cheaper fix: swap the 130,000 dollar large-firm line for 130,000 dollars to a small US agency whose employees do the work. Now only the 220,000 dollar offshore pod is counted, and the agency is inside the limit with 80,000 dollars to spare.
Some costs are not counted. Section 125.6(a)(1) says other direct costs may be excluded to the extent they are not the principal purpose of the acquisition and small businesses do not provide the service. The SBA's examples are airline travel and cloud computing services. Software licences you resell and hosting fall near that line, so ask the contracting officer how a particular cost will be treated before you rely on the exclusion.
Compliance is measured over a period, not at each invoice. Section 125.6(d) says the period used is generally the base term and then each option period. For the agency above, that means one test over the 12-month base term, so a heavy early outsourcing month does not decide it by itself. It also means you cannot wait until month eleven to discover you are off track.
What happens if you miss it?
Past performance first. Under section 125.6(e), where the agency determines at the end of performance that the limit was not met, it must notify the firm and let it explain mitigating circumstances. If none is shown, or the failure was within the firm's control, the agency may not give a satisfactory or higher past performance rating for the relevant factor. For an agency whose next award depends on past performance, that rating is the practical penalty, before any fine.
Section 125.6(h) then points to the penalties in 15 U.S.C. 645(d), with the fine set at the greater of 500,000 dollars or the amount spent over the limit, and notes that failing the spirit of a subcontract with a similarly situated entity may be grounds for debarment. Contracting officers can also ask for compliance evidence at any time during performance (section 125.6(f)(4)).
When is an offshore bench still the right answer?
On commercial and non-set-aside work, where this rule does not apply. That is where overflow capacity solves the problem it solves best: a quote you cannot staff at the margin the job needs.
On a set-aside above the threshold, the honest answer for a lean agency is that an offshore pod should be sized to fit under the cap, or left out. If most of the build would have to be done by people the rule counts against you, the better move may be to bid as a prime only for work your own staff can deliver, or to team with similarly situated US small businesses. We will tell you when a pilot is the wrong fit; a partner who claims it always fits is selling.
If you hold commercial work you cannot staff and want a bench you can test with a paid pilot before anything client-facing depends on it, see how our agency partner arrangement works, or tell us the scope.
