Definition
The Small Business Subcontracting Program is a federal program that requires large businesses, called "other than small businesses", awarded federal contracts above certain dollar thresholds to provide small businesses with the maximum practicable opportunity to participate in the performance of that contract as subcontractors.
In simple terms, when a large company wins a big federal contract, the government requires them to give small businesses a meaningful share of the work.
The Simple Explanation
Imagine a large defense contractor wins a $500 million IT modernization contract with the Department of Defense. Under the Small Business Subcontracting Program, the contractor cannot simply keep all the work in-house. The government requires them to submit a Subcontracting Plan, a written commitment to award a defined percentage of subcontract dollars to small businesses, including small disadvantaged businesses, women-owned firms, veteran-owned firms, HUBZone businesses, and service-disabled veteran-owned businesses.
If the contractor meets or exceeds their goals, it reflects positively on their past performance record. If they fall short without a good reason, they can face financial penalties, and it can hurt their chances on future contracts.
This program is one of the most important pathways for small businesses to enter and grow in the federal market without competing directly for large prime contracts.
Defining a Small Business: What Qualifies Under the Subcontracting Program?
Before a company can benefit from the Small Business Subcontracting Program, either as a required subcontracting target or as a certified small business pursuing subcontracting opportunities, it needs to understand exactly how the federal government defines a small business.
The Official Small Business Definition
According to the Small Business Administration (SBA), a small business is a for-profit business that is independently owned and operated, not dominant in its field, and meets the size standards set by the SBA for its specific industry. The business must also be physically located and operating in the United States or its territories.
This sounds simple, but in practice, "small" means something very different depending on what industry your business is in.
How Size Is Determined: NAICS Codes and Size Standards
The SBA determines whether a business qualifies as small based on its North American Industry Classification System (NAICS) code, a standardized code that classifies businesses by the type of product or service they provide. Each NAICS code has its own size standard, and size standards are set in one of two ways:
- Annual receipts: The average gross revenue of the business over its last five completed fiscal years. Most non-manufacturing and service businesses are measured this way.
- Number of employees: The average number of employees over the last 24 months. Most manufacturing businesses are measured this way. General rules of thumb, though always verify against your specific NAICS code. Most manufacturing companies with 500 employees or fewer qualify as small
- Most non-manufacturing businesses with average annual receipts under $7.5 million qualify as small
- Some industries have significantly higher thresholds; for example, certain IT services and engineering firms can qualify as small with revenues up to $25 million or more
Why NAICS Codes Matter So Much
Your small business status is not fixed across all contracts; it is contract-specific. Every federal solicitation is assigned a NAICS code that best describes the work being procured. When you submit a bid, your size is evaluated against the size standard for that specific NAICS code, not your primary business NAICS code.
This means a company could qualify as small for one type of contract and not qualify for another, depending on the NAICS code assigned.
The Affiliation Rule: A Critical Consideration
One of the most important, and most often misunderstood, aspects of the small business definition is the affiliation rule. When calculating your size, the SBA requires you to count the employees and revenues of all affiliated businesses, not just your own company.
Affiliation exists when one entity has the power to control another, through ownership, common management, contractual relationships, or family ties. The keyword is power to control; even if that control is never exercised, the affiliation still counts.
This matters enormously in teaming and subcontracting contexts. An improperly structured teaming arrangement or a close financial relationship with a large company could trigger an affiliation finding, stripping a business of its small business status for a specific procurement.
How to Check Your Small Business Status
- Use SBA's Size Standards Tool at sba.gov/size-standards to look up your NAICS code and verify your eligibility
- Self-certify your size status when registering in SAM.gov; your size status is reflected in your entity registration
- Size standards are reviewed and updated every five years by the SBA, so a business that did not qualify as small previously may qualify after a revision, and vice versa

Always verify against your specific NAICS code using SBA's official Size Standards Table at sba.gov. Thresholds are reviewed and updated every five years.
Legal Foundation
The Small Business Subcontracting Program is based on Public Law 95-507, passed in 1978, which established the requirement for large prime contractors to create opportunities for small business participation. It is implemented through FAR Subpart 19.7 and the key contract clause FAR 52.219-9, Small Business Subcontracting Plan.
Who Is Required to Have a Subcontracting Plan?
Subcontracting plans are required when:
- The prime contractor is an "other than small business", a large business, nonprofit, university, state or local government, or foreign-owned firm performing work in the U.S.
- The contract value exceeds $750,000 (or $1.5 million for construction contracts), including all options
Small businesses are exempt from this requirement; they are not required to submit subcontracting plans, even on large contracts.
Small Business Categories Covered
A subcontracting plan must set separate percentage goals for each of the following categories:
- Small Business (SB), the broadest category
- Small Disadvantaged Business (SDB), including 8(a) certified firms
- Women-Owned Small Business (WOSB)
- HUBZone Small Business firms in historically underutilized business zones
- Veteran-Owned Small Business (VOSB)
- Service-Disabled Veteran-Owned Small Business (SDVOSB)
Three Types of Subcontracting Plans
1. Individual Subcontracting Plan Tailored to a single specific contract. Goals and strategies are customized to match that contract's scope and subcontracting opportunities. A separate plan must be submitted for each contract. Most common for large, one-time awards.
2. Master Subcontracting Plan: A single plan that covers all of a contractor's federal contracts. More efficient for companies that regularly win multiple federal contracts, but it must still be reviewed and updated annually. Approved by one agency and recognized by all others.
3. Commercial Subcontracting Plan Used by contractors providing commercial products or services. Covers the contractor's entire commercial business, not just specific government contracts. Once approved, the government generally does not require a new plan as long as the commercial nature of the work remains the same.
What a Subcontracting Plan Must Include
Under FAR 19.704, a compliant subcontracting plan must contain:
- Percentage goals for subcontracting to each small business category
- Dollar value estimates of total subcontract dollars and the amounts allocated to each small business type
- Description of the principal types of supplies and services to be subcontracted
- A statement of good faith efforts, the contractor will make to ensure small businesses have the maximum opportunity to compete
- Assurance of timely payment, small business subcontractors must be paid within 90 days of the government paying the prime
- Reporting commitments, the contractor agrees to submit required reports through the Electronic Subcontracting Reporting System (eSRS)
- Flow-down requirements, the plan must include assurances that the FAR clause will flow down to any sub-tier subcontractors who also exceed the threshold
Reporting Requirements
Large prime contractors with subcontracting plans must submit two types of reports:
- Individual Subcontract Report (ISR): Submitted semi-annually, for periods ending March 31 and September 30, and again within 30 days of contract completion. Reports actual subcontracting dollars paid to each small business category.
- Summary Subcontract Report (SSR): Submitted annually by October 30. Summarizes subcontracting achievements across all contracts for a given agency.
Both reports are submitted through the Electronic Subcontracting Reporting System (eSRS) at esrs.gov.
Consequences of Non-Compliance
Failing to comply with a subcontracting plan is a serious matter. Consequences can include:
- Liquidated damages under FAR 52.219-16, the government can assess penalties equal to the amount by which the contractor failed to meet their subcontracting goals
- Negative past performance ratings can hurt the contractor's ability to win future federal contracts
- Corrective action plans, if a compliance review identifies deficiencies, the contractor must submit and follow a formal correction plan
- In extreme cases, suspension or debarment from federal contracting
Real-Life Context: Government-Wide Subcontracting Goals
The federal government sets government-wide small business prime and subcontracting goals each fiscal year. The overall goal is for small businesses to receive at least 23% of all federal contract dollars, both through direct prime contracts and through subcontracts under large prime contracts.
Individual agencies set their own goals within this framework, and large prime contractors negotiate their specific subcontracting plan percentages with contracting officers at the time of award. (Source: SBA.gov)
Key Resources for Finding Subcontracting Opportunities
For small businesses looking to find subcontracting opportunities under large prime contracts:
- SUBNet (SBA's Subcontracting Network): sba.gov/subnet, Large businesses post subcontracting opportunities here
- SBA's Directory of Federal Government Prime Contractors with a Subcontracting Plan: Lists large primes required to subcontract with small businesses
- Dynamic Small Business Search (DSBS): Used by prime contractors to find qualified small business subcontractors
- GSA Subcontracting Directory: Lists GSA prime contractors with subcontracting plans
- Agency-specific directories: DOT, DoD, and other agencies maintain their own subcontracting directories
Common Terms Associated with the Small Business Subcontracting Program
The Small Business Subcontracting Program in the SLED Market
The federal Small Business Subcontracting Program is a federal requirement; it does not automatically apply to state and local government contracts. However, many SLED jurisdictions have established their own equivalent programs, often with similar intent and structure.
SLED equivalents and related programs:
- Minority and Women-Owned Business Enterprise (MWBE) requirements: Many states and large municipalities require prime contractors on public contracts to subcontract a minimum percentage of work to MWBE-certified firms. New York, California, Illinois, and Texas all have active MWBE programs with mandatory participation goals.
- Disadvantaged Business Enterprise (DBE) program: Federally funded transportation projects administered by state DOTs are required to set DBE participation goals for subcontracting, a direct federal requirement that flows to SLED agencies receiving federal highway and transit funds.
- Local small business preferences: Some cities and counties maintain local small and emerging business programs with subcontracting goals for public contracts.
- Supplier diversity programs: Many large public universities and school districts have voluntary or mandatory supplier diversity programs that mirror federal subcontracting goals in spirit.
For vendors targeting SLED, particularly MWBE, SDVOSB, HUBZone, or other certified firms, understanding both the federal subcontracting program and your state's equivalent requirements is essential for positioning yourself as a subcontracting partner to large prime contractors.
Quick Summary
The Small Business Subcontracting Program requires large federal contractors awarded contracts over $750,000 to submit formal subcontracting plans with percentage goals for awarding work to small businesses across six categories. Plans must be reported on semi-annually and annually through eSRS. Non-compliance can result in financial penalties and damaged past performance ratings. For small businesses, this program is one of the most accessible pathways into federal contracting, and for SLED vendors, equivalent MWBE and DBE programs create similar subcontracting opportunities at the state and local level.
