Most service-disabled veteran-owned small businesses hit the same wall. The set-aside is perfect. The certification is in hand. But the contract is bigger than the company, the past performance is thin, or the bonding is not there. The answer is almost always a partner. The question is which kind of partnership, because the wrong structure can cost you the award, trigger a size protest, or put your VetCert status at risk.

This guide explains the three ways SDVOSBs team in 2026-2027: the teaming agreement (prime and subcontractor), the SDVOSB joint venture, and the mentor-protégé joint venture. It covers the rules that actually decide protests, with citations, plus a checklist you can use before you sign anything.

Short version: For an SDVOSB set-aside, a joint venture must have a VetCert-certified SDVOSB as managing venturer, the SDVOSB partner(s) must perform at least 40% of the JV's work, and the JV as a whole must meet the limitations on subcontracting (50% for services). A JV can win contracts for two years from its first award. SBA does not certify the JV itself; you designate it in SAM.gov.

Why Teaming Matters More in 2026-2027

Three changes make partnering decisions more important now than they were two years ago.

Option 1: The Teaming Agreement (Prime and Subcontractor)

FAR Subpart 9.6 recognizes "contractor team arrangements." In practice, most small-business teaming agreements are prime-subcontractor deals: the SDVOSB bids as prime, and the partner agrees to perform part of the work as a subcontractor if the team wins.

When it works

The two rules that sink prime-sub teams

Limitations on subcontracting (13 CFR 125.6). On an SDVOSB set-aside, the prime may not pay firms that are not similarly situated more than:

Type of contractMaximum paid to non-similarly-situated subs
Services (except construction)50% of the amount paid by the government
Supplies / products50%, excluding cost of materials (or meet the nonmanufacturer rule)
General construction85%, excluding cost of materials
Special trade construction75%, excluding cost of materials

Work done by a similarly situated subcontractor, meaning another VetCert-certified SDVOSB that is small under the contract's NAICS code, counts as if the prime did it. That is a major advantage of teaming SDVOSB-to-SDVOSB.

Bar chart of limitations on subcontracting: services 50 percent, supplies 50 percent, special trade construction 75 percent, general construction 85 percent maximum paid to non-similarly situated subcontractors
Limitations on subcontracting under 13 CFR 125.6. Similarly situated SDVOSB subcontractors do not count against these limits.

The ostensible subcontractor rule (13 CFR 121.103(h)). If a subcontractor performs the primary and vital requirements of the contract, or the prime is unusually reliant on it, SBA can treat the two as affiliated joint venturers. If the sub is large, the prime becomes large for that procurement and loses the award. Warning signs reviewers look for:

The safest prime-sub team is one where the SDVOSB clearly performs the core work and the sub fills a defined, secondary role.

Option 2: The SDVOSB Joint Venture

When the work is too big or too specialized for a prime-sub team, a joint venture lets two or more firms bid as one offeror. SBA's rule for VOSB and SDVOSB joint ventures is 13 CFR 128.402. The key requirements:

Who can be in the JV

Size

A JV of a certified SDVOSB and other firms is small if each partner is small under the NAICS size standard for the procurement. This applies to competitive and sole-source awards. A mentor-protégé JV is small if the protégé is small, no matter how big the mentor is.

Control and management

Work share and profits

Paperwork SBA requires in the JV agreement

13 CFR 128.402(c) lists required provisions. Among them: a special bank account in the JV's name, records kept at the managing venturer's office, quarterly financial statements within 45 days of each quarter, and a project-end profit and loss statement within 90 days of completion. Missing provisions are a common reason JV offers are found ineligible.

Certification and reporting

The two-year rule

Under SBA's affiliation rules, a joint venture may be awarded contracts for two years from the date of its first award. After that window, it can keep performing the contracts it already won, including orders under those contracts, but it cannot win new ones. Plan for a new JV entity if the partnership is long term.

Option 3: The Mentor-Protégé Joint Venture

SBA's single mentor-protégé program, at 13 CFR 125.9, is the strongest tool an SDVOSB has for competing on large set-asides. A large business mentor can JV with its SDVOSB protégé, and the JV is still small for set-asides as long as the protégé is small.

RuleRequirement
ApprovalSBA must approve the mentor-protégé agreement before the JV submits an offer.
TermNo more than six years total.
Protégés per mentorGenerally no more than three at a time.
Protégé sizeSmall for its primary NAICS code, or a secondary code it identifies for development.
AffiliationA protégé is generally not affiliated with its mentor because of assistance received under the approved agreement.
Work shareThe protégé must perform at least 40% of the JV's work, and more than administrative tasks.
ReportingAnnual protégé report to SBA, including JV contracts and mentor subcontracts.

The catch is that the protégé must really learn and lead. If the mentor runs the contract and the protégé is a name on the door, the JV will fail the work-share and control tests, and the SDVOSB's certification can be questioned.

Which Structure Should You Use?

SituationBest fit
You can do most of the work and need a specialist for a defined piecePrime-sub teaming agreement
The partner is another certified SDVOSBPrime-sub with a similarly situated sub, or an SDVOSB-SDVOSB JV
The work needs a partner's capacity and both firms are smallSDVOSB joint venture
You need a large firm's past performance, bonding, or systemsMentor-protégé JV (after SBA approves the agreement)
The partner would do the "primary and vital" workDo not structure it as prime-sub. Use a JV or pass.

What Goes in an SDVOSB Teaming Agreement

A teaming agreement is a contract. Have a government contracts attorney review it. At a minimum, it should cover:

  1. The specific opportunity by solicitation number or a clear description, so the agreement does not bind you forever.
  2. Work share by labor category, task, or percentage, written so you can prove compliance with the limitations on subcontracting.
  3. Exclusivity, if any, and when it ends.
  4. Proposal responsibilities: who writes what, who pays for what, and deadlines.
  5. The commitment to subcontract on award, subject to customer approval, and how pricing will be set.
  6. Termination: what happens if the team loses, the solicitation is canceled, or the government objects to the sub.
  7. Confidentiality and non-solicitation of employees.
  8. Compliance flow-downs, including cybersecurity clauses for DoD work and the limitations on subcontracting clause.

Red Flags That Lead to Lost Protests

What to Watch in 2026-2027

How to Form an SDVOSB Joint Venture, Step by Step

  1. Confirm both firms' status. The SDVOSB partner's VetCert certification must be active, and every partner must be small under the NAICS code of the target procurement, unless it is an approved mentor in a mentor-protégé JV.
  2. Pick the opportunity first. JVs are usually formed for a specific pursuit or a short list of related ones. Remember the two-year award window starts with the first award.
  3. Decide the structure. An unpopulated JV, where each partner performs with its own employees, is the most common for small firms. A separate LLC must be at least 51% owned by the SDVOSB.
  4. Write the JV agreement with every provision SBA requires: purpose, managing venturer, Responsible Manager, ownership, profit split, special bank account, records, financial statements, and a description of each partner's work.
  5. Map the work share. Break the scope into tasks and assign them. Check that the SDVOSB performs at least 40% of the JV's work and that the JV meets the limitations on subcontracting.
  6. Register the JV in SAM.gov. The JV gets its own UEI and CAGE code. Designate it as an SDVOSB joint venture and identify the certified partner.
  7. Submit the offer as the JV. Each certified partner certifies its own status and size at initial offer.
  8. Before award, the SDVOSB submits the signed certification to the contracting officer and SBA that the JV agreement complies.
  9. After award, track performance of work monthly and submit the annual and final performance-of-work reports.

Example: How the Work and Money Flow

Here is a simplified example of an unpopulated SDVOSB-mentor JV on a $10 million services contract. The numbers are illustrative.

ItemSDVOSB protégéLarge mentorOutside subs
Share of JV's own work45%55%-
Labor dollars performed$3.6 million$4.4 million$2.0 million
RoleManaging venturer, program manager, core technical workSpecialized technical work, reach-back, systemsNiche tasks

In this example the JV performs $8 million of the $10 million with its own partners, well inside the 50% services limit, and the SDVOSB performs 45% of the JV's work, above the 40% minimum. The profit split should match each partner's share of the work, or give the SDVOSB more.

Check the math every month, not at the end. Staffing changes, especially when a key SDVOSB employee leaves, can push the protégé below 40% without anyone noticing until the annual report.
Bottom line: Pick the structure based on who will actually do the core work. Write it down, certify it, and track it every month. The paperwork protects the award.

Frequently Asked Questions

Can an SDVOSB joint venture with a non-veteran company?

Yes. A certified SDVOSB can JV with another small business, or with its SBA-approved mentor, which may be large. The SDVOSB must be the managing venturer and perform at least 40% of the JV's work.

Does the joint venture need its own VetCert certification?

No. SBA does not certify VOSB or SDVOSB joint ventures. Each certified partner must be certified, and the JV is designated as an SDVOSB joint venture in SAM.gov with the certified partner identified.

How long can an SDVOSB joint venture win contracts?

Two years from the date of its first award. After that it can keep performing existing contracts and their orders, but it cannot receive new awards.

What is a similarly situated entity?

A subcontractor that holds the same certification as the prime (for an SDVOSB set-aside, another certified SDVOSB) and is small under the NAICS code the prime assigns to the subcontract. Work it performs counts toward the prime's limitations on subcontracting.

Is a teaming agreement the same as a joint venture?

No. In a typical teaming agreement the SDVOSB is the prime offeror and the partner is a subcontractor. In a joint venture the firms submit one offer together as a single entity, under SBA's joint venture rules.
