13 CFR 125.8: Joint Venture Agreement, 40% Rule, and Reports

13 CFR 125.8 is the Small Business Administration regulation that sets the requirements a joint venture must meet to submit an offer on a federal contract set aside or reserved for small business. It applies to every small business set-aside, not just the 8(a) Business Development program, and the tightest rules kick in when one of the partners is an SBA-approved mentor.¹ If you are considering a joint venture to chase set-aside work, the sections below walk through what the regulation actually requires, in the order the questions tend to come up.

What Contracts the Rule Applies To

The regulation reaches any federal procurement set aside or reserved for small business. That includes contracts reserved for service-disabled veteran-owned, women-owned, and HUBZone businesses, along with 8(a) contracts.¹

It has two tiers. A general eligibility rule lets any group of small businesses bid together. A more detailed set of structural requirements applies when the joint venture pairs a small business protégé with its SBA-approved mentor under 13 CFR 125.9. Most of the provisions people associate with 125.8, including the managing venturer designation, the special bank account, and the 40 percent protégé work rule, live in that second tier.

Size Standards and the Affiliation Exception

Under 125.8(a), a joint venture of two or more businesses can bid as a small business if each partner individually qualifies as small under the size standard for the NAICS code assigned to the contract.¹ If either partner exceeds the threshold on its own, the venture does not qualify under this general rule.

Ordinarily the SBA would treat joint venture partners as affiliated and combine their revenues or employees. That would push most joint ventures over the line. Two exceptions prevent that. Under 125.8(a), partners are not affiliated solely because of the joint venture, as long as each is independently small. A separate exception under 13 CFR 121.103 lets a large mentor pair with a small protégé without combining their sizes.² That second exception is what makes mentor-protégé joint ventures workable. Without it, adding a large firm to the team would blow the size standard on day one.

How the Joint Venture Can Be Structured

The regulation does not force a joint venture to become a separate legal entity. A joint venture under 125.8 can either be a formal entity such as an LLC, or an informal arrangement governed by a written agreement.¹

The choice changes how the contract is executed. If the venture is a separate entity, the agency executes the contract in the entity’s name. If it is informal, the contract is written in the name of one of the small business partners. Either way, the award is identified as a small business joint venture or a mentor-protégé joint venture. When partners do form a separate entity, the small business protégé must own at least 51 percent of it.

What the Written Agreement Must Contain

Every mentor-protégé joint venture must have a written agreement that includes several specific provisions. Missing any one of them can make the venture ineligible for award, and there is no informal fix once a bid is in.

A provision setting forth the purpose of the joint venture.
Designation of the small business as the managing venturer, and designation of a named employee of the small business as the Responsible Manager with ultimate authority over contract performance.¹
A dedicated bank account in the joint venture’s name. All government payments go into it, all contract expenses come out of it, and withdrawals to the partners for services require the signature or consent of all parties.
A profit-distribution provision under which the small business receives profits at least commensurate with the work it performs. A larger share is allowed; a smaller share is not. On termination, remaining funds are distributed by ownership percentage.
An itemized schedule of major equipment, facilities, and other resources each partner will contribute, with cost or value where practical. For indefinite-delivery contracts, a general description of anticipated resources works, or the agreement can spell out how resources will be furnished once the scope becomes known.³

Who Runs the Work

The Responsible Manager provision is one of the regulation’s most important safeguards. That person must be a named employee of the small business managing venturer and carries ultimate responsibility for performance. The managing venturer itself controls the day-to-day management and administration of the contract work.¹

A detail that trips up bidders: the Responsible Manager does not have to be employed by the small business when the offer goes in. If the person is not yet on the payroll, the agreement must include a signed letter of intent committing that individual to join the small business if the venture wins. One hard limit applies. The Responsible Manager cannot be someone currently working for the mentor who plans to switch employers to fill the role. The regulation explicitly prohibits a mentor employee from becoming an employee of the small business for purposes of performing under the joint venture.

The mentor, as non-managing venturer, can still weigh in on corporate-governance decisions such as which contracts to pursue or whether to bring litigation on the venture’s behalf. What it cannot do is exercise negative control over the venture’s activities, unless that kind of veto right would be commercially customary in a joint venture outside SBA programs. The line between governance participation and operational control is where many ventures run into trouble on SBA review.

The 40 Percent Protégé Work Rule

For mentor-protégé joint ventures, the small business protégé must perform at least 40 percent of the work done by the joint venture’s partners.¹ The calculation uses the same methodology as 13 CFR 125.6, which caps how much of a small business set-aside prime contract can go to firms that are not similarly situated small businesses. Those caps run from 50 percent for services and supplies up to 85 percent for general construction, with 75 percent for specialty trade construction.⁴

The 40 percent protégé workshare and the overall subcontracting limits apply at the same time. The venture has to satisfy both. When measuring the mentor’s share, the SBA counts everything performed by the mentor and any of its affiliates at any subcontracting tier. Work done by a similarly situated entity, meaning another small business that independently qualifies for the set-aside, does not count toward the protégé’s 40 percent.

The protégé’s work also has to be substantive. Handling only paperwork or clerical tasks does not satisfy the rule, no matter how the hours add up. The protégé must gain real experience from its role on the contract.

Certifications and Reports During Performance

Compliance with 125.8 is not a one-time exercise at the bidding stage. Documentation obligations run through the life of the contract.

Pre-Performance Certification

Before work begins on any set-aside contract awarded to a mentor-protégé joint venture, the small business partner must submit a written certification to both the contracting officer and the SBA. Authorized officials of each partner sign it. The certification confirms that the joint venture agreement contains every required provision and that the partners will perform the contract in accordance with the agreement and the work-share rules.¹

Annual and Completion Reports

During performance, the small business partner must file an annual report with the contracting officer and the SBA, signed by authorized officials of both partners, explaining how the performance-of-work requirements are being met for each set-aside contract performed that year. At contract completion, a final report explains how the work requirements were met and certifies that the contract was performed in accordance with the joint venture agreement’s required provisions. The SBA or contracting officer can also request that completion report before the contract is finished.

Past Performance on Future Bids

One of the reasons small firms enter a joint venture is how past performance gets evaluated on the next bid. Federal acquisition rules require the agency to consider the past performance of the joint venture itself when it submits an offer. If the venture has no record of its own, the agency must look at the past performance of each individual partner.⁵

Section 125.8(e) reinforces this. When evaluating capabilities, experience, and business-system certifications, the procuring agency must consider qualifications held individually by each partner as well as work the joint venture has previously performed. The agency has discretion to award a contract based on the mentor’s past performance alone, without requiring the protégé to independently demonstrate experience. That is how a small firm with a thin record can compete for work it could not win on its own.

SBA Approval and Its Limits

The mentor-protégé relationship under 13 CFR 125.9 is the gateway to the strongest benefits in 125.8: the affiliation exclusion, the ability to use the mentor’s past performance, and the structured framework for teaming with a larger firm. Without an SBA-approved Mentor-Protégé Agreement in place before the offer goes in, none of those special provisions apply.

The SBA no longer reviews and approves joint venture agreements formed to pursue competitive 8(a) contracts. It still reviews and approves agreements for sole-source 8(a) contracts.² On competitive procurements, the burden falls entirely on the partners to make sure the agreement meets every regulatory requirement. There is no SBA review catching deficiencies before the bid is submitted.

There are also structural limits on how mentors use the program. A mentor with multiple protégés cannot submit competing offers on the same procurement through separate joint ventures with different protégés, and a mentor cannot hold contracts through joint ventures with two different protégé firms on the same multiple-award contract at the same time.⁶

A Note on Classified Contracts

For joint ventures pursuing classified work, the clearance rules are more flexible than many bidders assume. The joint venture entity itself does not need to hold a Facility Security Clearance as a condition of award. The requirement is met as long as whichever partner will actually perform the classified work holds the necessary clearance. No entity needs a clearance simply to bid on or receive a classified contract, but the clearance must be in place before any classified work begins. After award, the cognizant security agency may require the joint venture to undergo an Entity Eligibility Determination if the venture itself will perform classified activities. When every member already holds a clearance, no additional determination is needed.

What Happens If You Get It Wrong

The consequences of violating 125.8 go well beyond losing a single contract. The regulation identifies three grounds for suspension or debarment from federal contracting: failing to have a compliant joint venture agreement, failing to perform the contract in accordance with the agreement or the work-share requirements, and failing to submit the required pre-performance certification.¹ Each is treated as a willful violation of a regulatory requirement applicable to a public agreement.

The Department of Justice also pursues joint venture violations under the False Claims Act when a contractor misrepresents its compliance to the government. Federal courts have held that the limitations-on-subcontracting clause is a material portion of the contract, which makes non-compliance a basis for False Claims Act liability. The standard is knowing or reckless conduct, meaning a contractor that ignores the work-share rules or files misleading reports faces civil penalties per false claim plus triple the government’s damages.⁷ Settlements in reported cases have reached into the hundreds of thousands of dollars, including a $400,000 settlement involving a non-small business that managed a joint venture and used its own employees for nearly all the work, and a $928,000 settlement where a mentor failed to form a qualifying joint venture at all.
