Set-asides are one of the most powerful advantages in federal contracting. The government reserves a portion of its contracts exclusively for specific types of businesses — small businesses, veteran-owned firms, minority-owned companies, and businesses in economically distressed areas. If you qualify, you're not competing against Fortune 500 companies — you're only competing against peers. The federal government is legally required to award at least 23% of all contract dollars to small businesses.

Detailed Guide
Who Qualifies & How to Apply
SBA Small Business 981 active
Reserved for businesses that qualify as "small" under SBA size standards based on NAICS code.
Who Qualifies
Any business that meets the SBA size standard for their NAICS code — typically under $25M–$40M in annual revenue for services, or under 500–1,500 employees for manufacturing.
How to Get Certified
Self-certification is sufficient for basic Small Business set-asides. No formal certification process required — just verify your NAICS code size standard.
Why It Matters
The government is required by law to award at least 23% of all contracts to small businesses. This is the most common set-aside type and applies to hundreds of thousands of solicitations each year.

Who Qualifies

Extremely powerful — 8(a) companies can receive sole-source awards without bidding. The government obligates over $30 billion to 8(a) firms annually.

SDVOSB Service-Disabled Veteran-Owned Small Business 204 active
Reserved for small businesses at least 51% owned by veterans with a service-connected disability.
Who Qualifies
U.S. military veteran with a service-connected disability rating, owning 51%+ of a small business. Must be verified in the VA's Vendor Information Pages (VIP) database.

Why It Matters
The VA alone is required to award 12% of contracts to SDVOSBs. All other agencies have a 3% goal. Over $25B in SDVOSB contracts are awarded annually.

Reserved for small businesses at least 51% owned and controlled by one or more women.

How to Get Certified
Self-certify or get certified by an approved third-party certifier. No SBA approval required for most awards under the WOSB threshold.

HUBZone HUBZone 12 active
Reserved for small businesses located in Historically Underutilized Business Zones — economically distressed areas.
Who Qualifies
Small business with principal office in a HUBZone area, and at least 35% of employees living in a HUBZone. The business owner does not need to live in the zone.
How to Get Certified
Apply for HUBZone certification through the SBA. The process takes about 90 days. Must maintain the 35% employee requirement continuously.

VOSB Veteran-Owned Small Business 1 active
Reserved for small businesses at least 51% owned by U.S. military veterans (no disability requirement).
Who Qualifies
Any veteran (DD-214 discharge), owning 51%+ of a small business. Disability rating is not required.
How to Get Certified
Register and verify through VA's VIP program. Primarily used by the VA for non-SDVOSB eligible contracts.
Why It Matters
VA's goal is 12% combined for VOSB/SDVOSB. Most other agencies use SDVOSB designation — VOSB is primarily relevant for VA-specific work.

Can I qualify for multiple set-asides?

Yes — a business can hold multiple certifications at the same time. For example, a woman-owned veteran-owned small business in a HUBZone could qualify as WOSB, SDVOSB, and HUBZone simultaneously. Each certification makes you eligible for that specific set of solicitations. More certifications = more doors open to you. The only restriction is that you can only be awarded one set-aside type per individual contract.
