Small Business Set-Aside Contracts: A Complete Guide to Federal Programs

What Are Set-Asides?

Small business set-asides are federal procurement mechanisms that restrict competition for certain government contracts to qualified small businesses. Rather than competing against large defense contractors and multinational corporations, small businesses compete only against other small businesses (or, in some cases, receive contracts without competition at all through sole-source authority).

The legal foundation comes from the Small Business Act, which requires the federal government to award a "fair proportion" of contracts to small businesses. Congress has since expanded this into multiple programs targeting different categories of disadvantaged or underrepresented businesses. In fiscal year 2023, set-aside programs accounted for over $160 billion in federal contract awards. Many small businesses leave that money on the table because they do not know which programs they qualify for.

Federal Percentage Goals

The federal government sets annual percentage goals for contracting with small businesses. These are government-wide targets that agencies are measured against:

• 23% of all prime contracts to small businesses (overall goal)
• 5% to small disadvantaged businesses (including 8(a) firms)
• 3% to HUBZone-certified businesses
• 3% to service-disabled veteran-owned small businesses (SDVOSB)
• 5% to women-owned small businesses (WOSB)

These goals are not quotas — agencies are not required to hit them exactly — but they create strong incentives for contracting officers to actively seek out small business sources. Agencies that consistently miss their goals face scrutiny from the SBA and Congress. In fiscal year 2023, the federal government exceeded its overall 23% goal, awarding over 27% of eligible contracting dollars to small businesses.

Each major agency also has its own small business goals, negotiated annually with the SBA. The Department of Veterans Affairs and the General Services Administration consistently exceed government-wide averages — if you are a small business, those agencies are worth targeting first.

Small Business Set-Aside (Total & Partial)

The most common type of set-aside is the general small business set-aside, governed by FAR Part 19. Under the "Rule of Two," a contracting officer must set aside a procurement for small businesses when there is a reasonable expectation that at least two responsible small businesses will submit competitive offers at fair market prices.

Set-asides come in two forms:

• Total set-aside: The entire contract is restricted to small businesses. Only firms that qualify as small under the assigned NAICS code can submit proposals.
• Partial set-aside: A portion of the contract is set aside for small businesses while the remainder is open to full and open competition. This is common for large, multi-award contracts like IDIQs.

To qualify for general small business set-asides, your business must simply meet the SBA size standard for the NAICS code assigned to the contract. No special certification is required — you self-certify your size status in your SAM.gov representations and certifications. However, competitors can challenge your size through an SBA size protest if they believe you do not qualify.

8(a) Business Development Program

The 8(a) Business Development Program is the SBA's flagship program for small, disadvantaged businesses. Named after Section 8(a) of the Small Business Act, this nine-year program provides participants with access to sole-source contracts, business development assistance, mentoring, and preferential access to federal procurements.

Key benefits of 8(a) certification include:

• Sole-source contracts up to $4.5 million for services and goods and $7 million for manufacturing — without competition.
• Competitive 8(a) set-asides restricted only to other 8(a) firms, a much smaller competitive pool than general small business set-asides.
• Joint ventures with larger firms through the mentor-protege program, allowing you to pursue larger contracts than you could alone.
• Business development assistance from the SBA, including training, counseling, and marketing support.

The program is divided into two stages: a four-year developmental stage and a five-year transitional stage. During the transitional stage, 8(a) firms are expected to become less dependent on set-aside contracts and more competitive in the open market. Eligibility requirements include social and economic disadvantage of the owner(s), small business size, demonstrated potential for success, and good character.

HUBZone Program

The Historically Underutilized Business Zone (HUBZone) program is designed to stimulate economic development and create jobs in distressed communities. HUBZone-certified firms receive contracting preferences for performing work in areas with high unemployment, low income, or other indicators of economic distress.

Benefits of HUBZone certification include:

• Competitive HUBZone set-asides restricted to HUBZone-certified firms.
• Sole-source contracts up to $4.5 million for services/goods and $7 million for manufacturing.
• 10% price evaluation preference in full and open competitions — if your price is within 10% of a non-HUBZone competitor, you can still win.

To qualify for HUBZone certification, your business must be small by SBA standards, owned and controlled by U.S. citizens, have its principal office in a HUBZone, and have at least 35% of its employees residing in a HUBZone. The SBA provides a HUBZone map tool on its website where you can check whether a specific address falls within a designated HUBZone.

SDVOSB Program

The Service-Disabled Veteran-Owned Small Business (SDVOSB) program provides contracting opportunities for businesses owned and controlled by veterans with service-connected disabilities. This program recognizes the sacrifices of disabled veterans by giving them preferential access to federal contracts.

SDVOSB benefits include:

• Competitive SDVOSB set-asides restricted to certified SDVOSB firms.
• Sole-source contracts up to $4.5 million for services/goods and $7 million for manufacturing.
• 3% government-wide goal — agencies actively seek SDVOSB contractors to meet this target.

As of January 2023, SDVOSB certification is handled by the SBA through the Veteran Small Business Certification (VetCert) program. Previously, businesses could self-certify as SDVOSB (except for VA contracts, which required VA verification). Now, all SDVOSB firms must be certified through the SBA to receive set-aside and sole-source contracts. The service-disabled veteran must own at least 51% of the business and control its daily operations and long-term strategy.

WOSB / EDWOSB Program

The Women-Owned Small Business (WOSB) Federal Contracting Program provides set-aside and sole-source authority for contracts in industries where women-owned businesses are underrepresented. The program has two tiers:

• WOSB (Women-Owned Small Business): For businesses at least 51% owned and controlled by one or more women who are U.S. citizens. Eligible for set-asides in industries determined by the SBA to be underrepresented by WOSBs.
• EDWOSB (Economically Disadvantaged Women-Owned Small Business): A subset of WOSBs where the women owners also demonstrate economic disadvantage (personal net worth under $750,000, excluding primary residence and business ownership). EDWOSBs can compete for both WOSB and EDWOSB set-asides, giving them access to a wider pool of opportunities.

Sole-source contracts under the WOSB program are available up to $4.5 million for services/goods and $7 million for manufacturing. Certification is handled by the SBA through the WOSB certification process, which was updated to require SBA or third-party certification (self-certification is no longer accepted).

How to Qualify

Each set-aside program has specific eligibility criteria, and most require certification from the SBA or an approved third party. Here is the general process:

1. Determine your size status. Use the SBA size standards table and your NAICS codes to verify that you qualify as a small business. This is the baseline requirement for all set-aside programs.
2. Register on SAM.gov. All contractors must have an active SAM.gov registration with accurate business information and representations.
3. Identify applicable programs. Review the eligibility criteria for each program (8(a), HUBZone, SDVOSB, WOSB) and determine which ones your business qualifies for.
4. Apply for certification. Submit your application through the SBA's certification portal (certify.sba.gov for most programs). Prepare supporting documentation including tax returns, financial statements, ownership documents, and program-specific evidence (e.g., disability rating letters for SDVOSB, HUBZone employee residence verification).
5. Maintain compliance. Once certified, you must meet ongoing compliance requirements including annual reviews, recertification, and reporting. Failure to maintain compliance can result in decertification.

Finding Set-Aside Contracts

Once you are certified, finding set-aside contracts is straightforward with the right tools. On SAM.gov, you can filter contract opportunities by set-aside type to see only the procurements restricted to your program. However, manually monitoring SAM.gov is time-consuming and you may miss opportunities posted across other sources.

Drexault pulls opportunities from SAM.gov, SBIR portals, DIBBS, DARPA, and other federal sources into one place. Filter by set-aside type — 8(a), HUBZone, SDVOSB, or WOSB — and get AI-scored recommendations matched to your capabilities and past performance.

Set-asides cut your competition dramatically. Instead of bidding against Lockheed Martin or Booz Allen, you compete against other small firms — or, with sole-source authority, you skip competition entirely. If your business qualifies for any of these programs, get certified before you do anything else.
