Teaming agreements open doors that are closed to contractors working alone. A small IT firm partners with a construction company to pursue a complex base modernization contract. A certified WOSB adds a cybersecurity specialist to its team and qualifies for a solicitation it could not win independently. The principle is straightforward: the right partnership expands what you can pursue.
But teaming in federal contracting comes with rules. The SBA's affiliation and ostensible subcontractor regulations got meaningful updates in 2025, and contractors who have not revisited their teaming documentation since then may be carrying compliance gaps they do not know about.
Here is how teaming agreements work, what compliance requires, and what changed.
What a Teaming Agreement Is
A teaming agreement is a written arrangement between two or more independent companies that come together to pursue a specific federal contract opportunity. One company takes the role of prime contractor. The others serve as subcontractors. The agreement formalizes the intent to collaborate on the bid and to negotiate a subcontract if the team wins.
A few distinctions that matter in practice:
Teaming agreements are not subcontracts. The teaming agreement covers the proposal phase and establishes intent. If the team wins, you negotiate a formal subcontract to govern actual performance. Courts have repeatedly found that teaming agreements alone are unenforceable as "agreements to agree," which means the subcontract is what protects each party's work share. Do not skip it.
Teaming agreements are not joint ventures. In a joint venture, two companies form a new legal entity to perform the contract together. In a teaming arrangement, each company retains its separate legal identity. The structure you choose matters significantly for SBA size and affiliation purposes.
Teaming agreements are opportunity-specific. A compliant agreement is tied to a specific solicitation number. Vague, open-ended teaming arrangements that are not connected to a defined pursuit create legal and compliance ambiguity.
Why Contractors Form Teaming Agreements
The strategic logic is direct:
Filling capability gaps. Federal solicitations often require combinations of technical capability, past performance, security clearances, and specialized experience that no single small business can satisfy alone. Teaming allows you to meet requirements your company cannot meet independently.
Past performance. Past performance evaluation is one of the most consequential factors in federal source selections. If your company lacks directly relevant past performance for a specific type of work, a teaming partner with that history can strengthen the overall proposal.
Set-aside access. Large businesses sometimes team with small businesses to access set-aside opportunities. Small businesses sometimes form "similarly situated" teams where all members share the same small business status, which provides compliance protections discussed below.
Competitive positioning. Agencies often prefer offerors who can demonstrate a fully assembled team with defined roles. A well-structured teaming agreement, disclosed in the technical proposal, signals organizational readiness.
What Compliance Requires
Independent Ownership and Control
The companies forming the team must be genuinely independent. They cannot share common ownership, common management, or control arrangements that would allow one to direct the decisions of the other. Any arrangement where one teaming partner effectively controls the other triggers SBA affiliation review.
Defined Roles and Work Share
The prime and subcontractor roles must be clearly stated. The agreement should specify what work each party will perform, expressed as percentages of contract value where possible. Vague work share language is one of the most common reasons teaming agreements fail under SBA scrutiny or result in post-award disputes.
The Ostensible Subcontractor Rule
This is the compliance area where most teaming problems originate. Under SBA regulations at 13 CFR 121.103(h), if a subcontractor performs the "primary and vital requirements" of a contract, or if the prime is "unusually reliant" on the subcontractor to perform, the SBA treats them as affiliated. That affiliation can disqualify the team from a small business set-aside entirely.
For service contracts, the prime must perform at least 50 percent of personnel costs using its own employees. For supply contracts, the prime must supply at least 50 percent of the contract value from its own production or from other small business manufacturers. These self-performance limits exist specifically to prevent small businesses from acting as pass-throughs for larger partners.
The practical implication: the prime must genuinely lead the contract. If the subcontractor is doing most of the work or providing the core technical expertise that makes the proposal competitive, you have an ostensible subcontractor risk that needs to be addressed before the proposal is submitted.
Disclosure in the Technical Proposal
Prime contractors must disclose teaming partners and subcontractors in their technical proposals. Post-award subcontracting activity is tracked through the Subcontracting Reporting System. Accurate disclosure from the proposal stage through performance is a compliance requirement, not an optional practice.
What Changed in 2025: SBA Rule Updates That Affect Teaming
The SBA's December 2024 final rule (effective January 16, 2025) made several changes that contractors working with teaming agreements need to understand.
Ostensible subcontractor rule clarification. The updated rule at 13 CFR 121.103(h) reinforced that if a subcontractor performs vital requirements or if the prime is unusually reliant on the subcontractor, the arrangement is ineligible for small business set-asides. This is not new in concept, but the 2025 rule tightened the language and added enforcement clarity.
Size recertification after M&A events. If your company undergoes a merger, acquisition, or change of controlling interest, you must recertify your size status within 30 days. As of January 17, 2026, businesses that recertify as "other than small" following an M&A event are no longer eligible for new task orders or options under existing small business multiple award contracts (MACs). This affects teaming strategy for businesses in growth or acquisition mode.
Negative control affiliation clarification. The rule updated the safe harbors for minority investors. Certain veto rights over extraordinary business decisions (dissolution, adding equity, major asset sales) no longer automatically trigger affiliation when held by minority investors. This creates more flexibility in structuring teaming and investment arrangements.
Similarly situated subcontractors. Teaming arrangements where all members share the same small business program status (all SDVOSB, all WOSB, all 8(a), etc.) carry lower affiliation risk under the updated rules. The subcontracting limitations that apply to work performed by the prime do not apply to work performed by a similarly situated subcontractor. If you can team with businesses that share your certification status, it is worth structuring your team that way.
Key Elements of a Compliant Teaming Agreement
A teaming agreement that will hold up under review and protect both parties typically includes:
The specific solicitation number or procurement the team is pursuing. Identification of the prime contractor and each subcontractor with their roles clearly stated. Work share percentages for each party. Intellectual property protections covering data, proposals, and proprietary information shared during the proposal phase. Exclusivity provisions specifying whether parties can join competing teams for the same opportunity. Termination conditions defining when the agreement expires (typically upon award loss or execution of a subcontract). Confirmation that both parties independently meet any size and certification requirements applicable to the solicitation.
What to avoid: open-ended teaming agreements not tied to a specific pursuit, work share language that is vague or aspirational, and arrangements where the subcontractor is effectively doing the prime's job.

Frequently Asked Questions
What is a teaming agreement in federal contracting? A teaming agreement is a written arrangement between two or more independent companies to pursue a specific federal contract opportunity together. One company serves as the prime contractor and the others as subcontractors. The agreement covers the proposal phase and establishes the intent to negotiate a formal subcontract upon award.
What is the difference between a teaming agreement and a joint venture? In a teaming arrangement, each company retains its separate legal identity. In a joint venture, the parties form a new legal entity to pursue and perform the contract. The structure choice affects how SBA affiliation rules apply and how performance obligations are divided.
What is the ostensible subcontractor rule? The SBA's ostensible subcontractor rule at 13 CFR 121.103(h) provides that if a subcontractor performs the primary and vital requirements of a contract, or if the prime is unusually reliant on the subcontractor, the two are treated as affiliated. That affiliation can disqualify the team from a small business set-aside. The prime must genuinely lead the work and meet applicable self-performance requirements.
How much work must the prime contractor perform? For service contracts, the prime must perform at least 50 percent of personnel costs using its own employees. For supply contracts, the prime must supply at least 50 percent of the contract value from its own or other small business production. These limits prevent small businesses from functioning as pass-throughs for larger subcontractors.
What changed with SBA affiliation rules in 2025? The SBA's December 2024 final rule, effective January 16, 2025, clarified the ostensible subcontractor standard, updated recertification requirements following mergers and acquisitions, and refined the negative control affiliation safe harbors for minority investors. As of January 17, 2026, businesses that recertify as other than small after an M&A event lose eligibility for new task orders under existing small business MACs.
What should a teaming agreement include? A compliant teaming agreement should identify the specific solicitation, define the prime and subcontractor roles, specify work share percentages, include IP protections, address exclusivity, and define termination conditions. It should be tied to a specific opportunity rather than left open-ended.
Does a teaming agreement guarantee a subcontract? No. Courts have generally found that teaming agreements are unenforceable as "agreements to agree." A separately executed subcontract is required to legally bind the parties to work share and payment terms after award.
