When two companies decide to chase a federal contract together, they make a structural choice that shapes liability, eligibility, and enforceability long before a proposal is due. FAR Subpart 9.6, Contractor Team Arrangements, defines the two forms that partnership can take, and the difference is anything but cosmetic. One form produces a single accountable prime with subcontractors behind it; the other produces a new entity that bids and bears liability as a whole. Getting the choice wrong can cost a small business its set-aside eligibility or leave a promised subcontract legally hollow.
Background
FAR 9.601 recognizes exactly two things under the label "contractor team arrangement." The first is where two or more companies form a partnership or joint venture to act as a potential prime contractor. The second is where a potential prime contractor agrees with one or more other companies to have them act as its subcontractors under a specified Government contract. That single definition draws the line the rest of the subpart runs along: a joint venture stands as the offeror itself, while a teaming agreement leaves one company as the prime and the others behind it as subcontractors.
The Government does not treat these arrangements as private business that stays private. FAR 9.602 frames their purpose plainly: team arrangements let the companies involved complement each other's unique capabilities and offer the Government the best combination of performance, cost, and delivery. They are particularly appropriate in complex research and development acquisitions, but they are equally available in other work, including production. The timing is flexible as well, because companies may form an arrangement before submitting an offer or enter into one later in the acquisition process, including after contract award, though the disclosure obligation attaches whenever the arrangement is formed. FAR 9.603 provides that the Government will recognize the integrity and validity of a team arrangement when the arrangement is identified and the company relationships are fully disclosed in an offer, or, for arrangements formed after submission, before the arrangement becomes effective, and it adds that the Government will not normally require or encourage the dissolution of such an arrangement. Disclosure, not permission, is the operative requirement.
Key Details
The sharpest distinction is who the Government holds responsible. In a prime-subcontractor teaming agreement, the prime is a distinct legal entity fully accountable to the Government, and the teammate is a subcontractor with no privity of contract with the agency. The subcontractor's size, socioeconomic status, and past performance do not transfer to the prime. In a joint venture, the JV itself is the offeror and awardee, and its members share liability for performance as members of that entity.
FAR 9.604 fences in what recognition of a team arrangement does and does not buy. Recognizing an arrangement never authorizes an antitrust violation, and it does not limit the Government's rights to require consent to subcontracts under Subpart 44.2, to assess prime contractor responsibility under Subpart 9.1, to control access to data the Government provides, or to pursue its policies on competitive contracting, subcontracting, and component breakout. Most pointedly, 9.604 preserves the Government's right to hold the prime contractor fully responsible for contract performance, regardless of any team arrangement. A prime cannot point at a defaulting teammate to shed its own accountability.
Small-business status is where the two structures diverge most consequentially. Under the SBA Mentor-Protege Program, a small-business protege can form a joint venture with a mentor that is a large business and still compete for small-business set-asides, an explicit exception to the normal affiliation rules that would otherwise disqualify the pairing. An ordinary teaming subcontract confers nothing of the sort: a subcontractor's small-business size does not make the prime small, and a large prime cannot borrow a small teammate's eligibility. The SBA states plainly that two or more small businesses may pool their efforts by forming a joint venture to compete for a contract award, and such a joint venture may bid on SDVOSB, WOSB, and HUBZone set-asides when a member meets the relevant requirements.
There is a durability problem unique to teaming agreements. A joint venture is a formed entity with its own governing agreement; a teaming agreement is frequently an agreement to agree, promising that the prime will award a defined scope of subcontracted work if the team wins. The enforceability of that promised subcontract has been litigated repeatedly, and courts have often found teaming agreements too indefinite to enforce when they leave price, scope, or terms to future negotiation. A teaming agreement is only as durable as it is definite.
What It Means for Contractors
The first decision is not legal boilerplate; it is a business-model decision made under FAR 9.601. If the goal is to combine two companies into a single competitor that shares work, risk, and reward as one, the joint venture is the vehicle, and it must be stood up as a real entity with a written JV agreement before the proposal names it as the offeror. If the goal is for one company to lead and buy specialized capability from partners, the prime-subcontractor teaming agreement fits, and the prime should go in understanding that FAR 9.604 leaves it holding full performance responsibility no matter how the team performs.
Small businesses should treat eligibility as the deciding factor rather than an afterthought. A large-mentor joint venture under the SBA program can unlock set-asides a subcontract never will, but only if the mentor-protege relationship and JV are properly established before award. Relying on a teaming subcontract to reach a set-aside the prime cannot otherwise qualify for is a recipe for a size protest.
Whichever structure a team picks, disclose it. FAR 9.603 conditions Government recognition on the arrangement being identified and the relationships fully disclosed in the offer, so a team that hides its structure forfeits the recognition the subpart offers. And when the vehicle is a teaming agreement, invest in definiteness: pin down the subcontracted scope, workshare percentage, and pricing basis in writing, because an agreement that defers those terms may not survive a dispute after the win.
