Federal small business set-aside programs

How set-asides work

Federal law (the Small Business Act and its implementing regulations) requires agencies to direct a portion of their contracting dollars to small businesses, with separate sub-goals for specific categories. The government-wide goal is 23% of all prime contracting dollars to small businesses, with sub-goals of 5% for 8(a)/disadvantaged firms, 5% for women-owned, 3% for HUBZone, and 3% for SDVOSB. Agencies are graded on whether they meet these goals every year.

The mechanism agencies use to hit those goals is the set-aside. When an agency identifies enough capable small businesses in a category to expect competition at fair prices, they restrict the solicitation to that category. Outside firms can’t bid. Inside firms compete against each other — a much smaller pool than the open market.

8(a) Business Development Program

The 8(a) program is a nine-year SBA-administered program for small businesses owned at least 51% by U.S. citizens who are socially and economically disadvantaged. Members of certain racial and ethnic groups are presumed disadvantaged; others must demonstrate it through narrative evidence. Owners must also meet personal net worth, income, and asset limits.

The defining feature of 8(a) is sole-source contracting. An agency can award a contract directly to an 8(a) firm without competition up to $4.5 million for most goods and services and $7.5 million for manufacturing — no proposals, no bid evaluation, no competitors. Above those thresholds, agencies use competitive 8(a) set-asides restricted to the program. The combined volume is roughly $26 billion in 8(a) prime contracts annually.

Application is through certify.sba.gov and typically takes several months. Once admitted, the firm has nine years in the program — broken into a 4-year “developmental” phase and a 5-year “transitional” phase. For a deeper look at how to use the certification, see our guide for 8(a) certified businesses.

HUBZone Program

HUBZone — Historically Underutilized Business Zones — is a geographically-defined program. To qualify, your business must:

• Be a small business under SBA size standards
• Have its principal office in a HUBZone (a designated rural area, urban empowerment zone, BRAC-affected community, or qualified disaster area)
• Have at least 35% of employees living in a HUBZone (any HUBZone, not necessarily the same one)
• Be at least 51% owned and controlled by U.S. citizens

HUBZone firms get access to set-aside contracts restricted to the program — roughly $20 billion annually — plus a 10% price evaluation preference in certain full-and-open competitions, meaning a HUBZone firm bidding 10% higher than a non-HUBZone competitor wins on price. Application is through certify.sba.gov; SBA verifies the geographic and employee residency requirements before granting certification, and recertifies annually. For a deeper look, see our guide for HUBZone businesses.

WOSB and EDWOSB

The Women-Owned Small Business program covers two related certifications: WOSB and EDWOSB (Economically Disadvantaged WOSB). Both require the firm to be at least 51% owned and controlled by women who are U.S. citizens. EDWOSB adds a personal net worth and income test on the owners.

WOSB and EDWOSB set-asides are restricted to NAICS codes where women are underrepresented in federal contracting — a list maintained by the SBA based on a periodic study. The list covers hundreds of codes including IT services, construction trades, professional services, and manufacturing. EDWOSB firms are eligible in a broader subset of those codes. The annual contract value is roughly $30 billion combined for WOSB and EDWOSB.

Application is through certify.sba.gov. As of 2020, self-certification is no longer accepted — firms must be SBA-certified or certified through an SBA-approved third-party certifier to bid on WOSB/EDWOSB set-asides. For more, see our guide for women-owned small businesses.

SDVOSB and VOSB

SDVOSB — Service-Disabled Veteran-Owned Small Business — is for businesses at least 51% owned and controlled by one or more veterans with a service-connected disability. The owners must manage the day-to-day operations and hold the highest officer position. Government-wide goal: 3% of prime contracting dollars, roughly $25 billion annually.

VOSB — Veteran-Owned Small Business, without the service-connected disability requirement — is primarily used inside the Department of Veterans Affairs through the VA’s Veterans First Contracting Program (sometimes called “Vets First”). VA spends billions per year on contracts set aside for VOSB and SDVOSB firms; outside the VA, the SDVOSB certification is the broadly-recognized one.

Certification is now through the SBA’s Veteran Small Business Certification (VetCert) at veterans.certify.sba.gov, consolidated from the older VA Center for Verification and Evaluation. For the full mechanics, see our guide for veteran-owned small businesses.

General small business set-asides

Even without a specialized certification, any small business that meets the SBA size standard for its NAICS code is eligible for general small-business set-asides. Federal acquisition regulations require contracting officers to set aside an acquisition for small business when there’s a reasonable expectation of receiving offers from at least two responsible small business concerns at fair market prices — the “Rule of Two.”

In practice, this means a meaningful share of the $700+ billion federal procurement market is already restricted to small businesses, regardless of whether you hold any other certification. If you qualify as small in your NAICS code, you can compete for those contracts the day you register in SAM.gov — no additional certification required. For a deeper look at small disadvantaged businesses specifically (a related but distinct category overlapping with 8(a)), see our guide for small disadvantaged businesses.

How to use a certification once you have one

A certification by itself doesn’t win contracts. What it does is unlock set-aside solicitations you couldn’t see before — and shrink the field you compete against on the ones you can. Three things to do once certified:

1. Update your SAM.gov registration to reflect the certification. Contracting officers search SAM.gov entity records when they look for capable certified vendors.
2. Filter your contract searches by the relevant set-aside type. SAM.gov, state portals, and ContractRadar all support set-aside filtering.
3. Look at past awards on USAspending.gov filtered to your certification — it shows you which agencies are actively buying from firms like yours, what they pay, and who’s winning.

ContractRadar profiles include certification fields. When you set yours, daily contract emails are ranked by relevance to your certifications — so 8(a) sole-source candidates and SDVOSB set-asides float to the top of your inbox, not the bottom.
