Government Contract Set-Asides: 8(a), WOSB, HUBZone, SDVOSB
2026-03-19 · GovContractData Team
The federal government is legally required to direct a percentage of contract spending to small businesses. In fiscal year 2024, the government's goal was 23% of prime contract dollars to small businesses overall, with specific targets for each set-aside category. These programs exist to level the playing field and ensure small firms can compete for federal work without being crowded out by large contractors.
This guide covers every major set-aside program: who qualifies, what the benefits are, dollar thresholds for sole-source awards, and how to find set-aside contracts relevant to your business.
What Set-Asides Are and How They Work
A "set-aside" restricts competition for a contract so that only qualifying small businesses can bid. The contracting officer makes this determination using the "Rule of Two": if at least two responsible small businesses can perform the work at a fair market price, the contract should be set aside for small businesses.
Set-asides can be:
- Total: Only qualifying small businesses can bid
- Partial: A portion of the contract is reserved for small businesses
- Sole-source: Awarded to a single qualifying firm without competition (within dollar limits)
The result is a smaller competitive pool, which significantly improves your odds of winning.
Federal Small Business Goals
The government sets annual targets for each category:
| Program | Annual Goal | FY2024 Actual | |---------|-------------|---------------| | All Small Business | 23% of prime contracts | Exceeded | | Small Disadvantaged Business (including 8(a)) | 13% | Exceeded | | Women-Owned Small Business (WOSB) | 5% | Met | | HUBZone | 3% | Below target | | Service-Disabled Veteran-Owned (SDVOSB) | 3% | Exceeded |
Agencies that miss their goals face scrutiny. This creates real institutional pressure to find and award contracts to qualifying small businesses.
8(a) Business Development Program
What It Is
The SBA's flagship program for small businesses owned by socially and economically disadvantaged individuals. "Socially disadvantaged" includes individuals who have faced racial or ethnic prejudice or cultural bias, as well as other qualifying circumstances. "Economically disadvantaged" means the owner's personal net worth is below $850,000 (excluding primary residence and business equity).
Eligibility Requirements
- At least 51% owned and controlled by one or more socially and economically disadvantaged individuals
- Owner must be a U.S. citizen
- Business must qualify as small under its primary NAICS code
- Owner's adjusted gross income must not exceed $400,000
- Owner's total assets must not exceed $6.5 million
- Business must demonstrate potential for success (typically two years of operations)
- Owner must manage day-to-day operations
Key Benefits
Sole-source contracts: The most valuable benefit. Agencies can award contracts directly to 8(a) firms without competition, up to these thresholds:
| Contract Type | Sole-Source Limit | |---------------|-------------------| | Services | $4.5 million | | Manufacturing | $7 million |
Competitive 8(a) set-asides: For contracts above the sole-source thresholds, agencies can restrict competition to only 8(a) firms.
Mentor-protege program: 8(a) firms can partner with larger mentors who provide technical assistance, financing help, and joint venture opportunities.
Business development assistance: SBA provides training, counseling, and marketing support throughout the nine-year program period.
Program Duration
The 8(a) program lasts nine years, divided into a four-year developmental stage and a five-year transitional stage. During the transitional stage, the firm is expected to win increasing amounts of non-8(a) work.
How to Apply
Apply through certify.sba.gov. The process takes 60 to 90 days. You will need financial statements, tax returns, resumes, and documentation of social disadvantage.
Women-Owned Small Business (WOSB) Program
What It Is
The WOSB Federal Contracting Program authorizes set-asides for women-owned small businesses in industries where women are underrepresented. The SBA maintains a list of eligible NAICS codes.
Eligibility Requirements
- At least 51% owned and controlled by one or more women
- Women must manage day-to-day operations and make long-term decisions
- Business must be small under its primary NAICS code
- Business must operate in a NAICS code designated by SBA as underrepresented
Two Subcategories
WOSB (Women-Owned Small Business): For industries where women are substantially underrepresented. Set-aside and sole-source eligible.
EDWOSB (Economically Disadvantaged Women-Owned Small Business): For women whose personal net worth is below $750,000. EDWOSBs can compete for both EDWOSB and WOSB set-asides, accessing a wider pool of opportunities.
Dollar Thresholds
| Award Type | WOSB Limit | EDWOSB Limit | |------------|------------|--------------| | Sole-source (services) | $4.5 million | $4.5 million | | Sole-source (manufacturing) | $7 million | $7 million | | Competitive set-aside | No dollar limit | No dollar limit |
How to Apply
Self-certify through certify.sba.gov or obtain third-party certification from an SBA-approved certifier. SBA may review your certification at any time.
HUBZone Program
What It Is
HUBZone (Historically Underutilized Business Zones) certification is for businesses located in and hiring from economically distressed communities. The program aims to stimulate economic development in underserved areas.
Eligibility Requirements
- Principal office must be in a designated HUBZone
- At least 35% of employees must reside in a HUBZone
- Business must be small under its primary NAICS code
- Business must be owned and controlled by U.S. citizens, a Community Development Corporation, an agricultural cooperative, an Indian tribe, or a Native Hawaiian organization
- Must be SBA-certified
Key Benefits
Competitive HUBZone set-asides: Contracts restricted to HUBZone firms only.
Sole-source contracts: Available up to:
| Contract Type | Sole-Source Limit | |---------------|-------------------| | Services | $4.5 million | | Manufacturing | $7 million |
10% price evaluation preference: On full and open competition contracts, HUBZone firms receive a 10% price advantage. If a HUBZone firm bids $110,000 and a non-HUBZone firm bids $100,000, the HUBZone firm is treated as if it bid $100,000 for evaluation purposes.
Maintaining Certification
HUBZone certification is not permanent. SBA recertifies firms every three years and requires the business to continue meeting the location and employee residency requirements. If your office moves out of a HUBZone or your employee residency drops below 35%, you lose certification.
Check whether your address is in a HUBZone using the SBA HUBZone map.
How to Apply
Apply through certify.sba.gov. Processing takes approximately 60 days. You will need lease documentation, employee addresses, and payroll records.
Service-Disabled Veteran-Owned Small Business (SDVOSB)
What It Is
Set-asides for small businesses owned and controlled by veterans with a service-connected disability rated by the VA. The government's goal is 3% of prime contract dollars to SDVOSBs.
Eligibility Requirements
- At least 51% owned and controlled by one or more service-disabled veterans
- Service-disabled veteran must manage day-to-day operations
- Business must be small under its primary NAICS code
- Disability must be service-connected and rated by the VA
Dollar Thresholds
| Contract Type | Sole-Source Limit | |---------------|-------------------| | Services | $4.5 million | | Manufacturing | $7 million |
VA vs. Federal-Wide
The VA has its own verification program through the SBA's Veteran Small Business Certification (VetCert). VA contracts require VetCert verification. For contracts with other federal agencies, self-certification through SAM.gov has historically been accepted, though SBA is transitioning all SDVOSB certification through VetCert.
How to Apply
Apply through the SBA's VetCert program at veterans.certify.sba.gov. You will need DD-214, VA disability rating letter, and business ownership documentation.
Small Business Set-Asides (General)
Even without a specific certification, any business that meets the SBA size standard for a given NAICS code can compete for general small business set-asides. These are the most common type of set-aside and do not require any certification beyond SAM.gov registration.
The contracting officer determines the size standard based on the NAICS code assigned to the solicitation. Size standards are based on:
- Average annual receipts (most service industries): typically $9 million to $47 million depending on the NAICS code
- Number of employees (most manufacturing industries): typically 250 to 1,500 employees
How to Search for Set-Aside Contracts on GovContractData
Search contract awards on GovContractData and filter by set-aside type to see:
- Which agencies award the most set-aside contracts in your NAICS codes
- Average award sizes for each set-aside category
- Which states have the most set-aside activity
- Who the incumbent contractors are in your market
You can combine set-aside filters with NAICS code, agency, and state filters to find exactly the contracts relevant to your certifications.
Browse set-aside awards by specific agencies like the Department of Defense or Department of Veterans Affairs to see which departments use set-asides most heavily.
Stacking Certifications
You can hold multiple certifications simultaneously. An 8(a) firm can also be WOSB, HUBZone, and SDVOSB certified if it meets all requirements. Multiple certifications expand the pool of set-aside contracts you can compete for.
However, each certification has its own maintenance requirements (annual reviews, recertifications, employee residency requirements for HUBZone). Only pursue certifications you can realistically maintain.
Getting Started
- Determine your size status. Check the SBA size standard for your primary NAICS code to confirm you qualify as small.
- Identify applicable programs. Review the eligibility requirements for each set-aside program above.
- Register in SAM.gov. List your NAICS codes and any certifications.
- Apply for certifications. Use certify.sba.gov for 8(a), WOSB, and HUBZone. Use veterans.certify.sba.gov for SDVOSB/VetCert.
- Research the market. Search set-aside contract awards on GovContractData to understand where the opportunities are in your industry.
