The Set-Aside Promise You Have to Keep: Limitations on Subcontracting

Published 2026 | TIKC NewsWire

Set-asides exist so that small businesses actually do the work, not so they can win the award and hand it to a large partner. That principle is enforced by a rule called the limitations on subcontracting, and it is one of the most common ways good small firms get into serious trouble. When you win a set-aside, you are promising to self-perform a minimum share of the work. Break that promise and you can lose the contract, face a steep statutory penalty, and hand the government a False Claims Act case.

What the rule actually requires

Under FAR 52.219-14 and 13 CFR 125.6, a small business that wins a set-aside or a socioeconomic program contract cannot pass most of the work to firms that are not small. The limits are expressed as how much you may pay to non-similarly situated subcontractors:

• Services: you may not pay more than 50 percent of the amount the government pays you to subcontractors that are not similarly situated.
• Supplies (other than as a nonmanufacturer): no more than 50 percent of the amount paid by the government, excluding the cost of materials, to non-similarly situated subs.
• General construction: no more than 85 percent to non-similarly situated subs.
• Specialty trade construction: no more than 75 percent.

The similarly situated carve-out that helps you

Here is the piece that makes teaming work. Work performed by a similarly situated entity, meaning a subcontractor in the same small business program (for example, another SDVOSB on an SDVOSB set-aside), does not count against your limit. So you can team broadly with other qualifying small firms and still meet the rule. The limit only bites when you push work down to firms that are not similarly situated, typically large businesses.

Why this is an enforcement issue, not just paperwork

You certify compliance with the limitation, and the government relies on it. If you knowingly exceed the limit while representing that you are meeting it, that misrepresentation can support a False Claims Act theory. On top of that, the Small Business Act carries a specific penalty for violations: the greater of $500,000 or the dollar amount spent over the allowed threshold on the offending subcontract (15 U.S.C. 645(d)). This is also where the ostensible subcontractor rule overlaps: if your non-small sub is really performing the primary and vital work, you may not be the small business performing the contract at all.

What to do now

• Plan the work split before you bid. Map who performs what, and confirm your self-performance clears the applicable threshold.
• Team with similarly situated firms when you need capacity, so their work does not count against your limit.
• Track it during performance. Measure actual dollars to non-similarly situated subs against the limit, not just the plan.
• Keep the records. Be able to show, contract by contract, that you met the requirement.
• Watch the primary and vital work. Do not let a large sub quietly run the core of the job.

A set-aside is a promise that you will do the work. Keep it deliberately, and the rule protects your award instead of threatening it. Brick by brick.

FAQ

What is a similarly situated entity?

A subcontractor that participates in the same small business program as the prime for that set-aside (for example, a HUBZone sub on a HUBZone contract). Its work does not count against your subcontracting limit.

How much of a services contract must I self-perform?

You may not pay more than 50 percent of the amount the government pays you to subcontractors that are not similarly situated. Work kept in-house or given to similarly situated firms satisfies the rule.

What is the penalty for violating the limitation?

Beyond losing the contract and possible False Claims Act exposure, the Small Business Act sets a penalty of the greater of $500,000 or the amount spent in excess of the permitted level (15 U.S.C. 645(d)).

How does this relate to the ostensible subcontractor rule?

They overlap. If a non-small subcontractor performs the primary and vital work, or you are unusually reliant on it, you may be treated as affiliated with it and not the small business actually performing the contract.
