Set-Aside Contracts Explained: Every Type, Who Qualifies, and How to Get Certified

The federal government doesn't just allow small businesses to compete for contracts — it actively reserves a massive portion of spending exclusively for them. These reserved contracts are called "set-asides," and they're the single biggest advantage a small business has in government contracting.

In fiscal year 2025, the government directed over $178 billion to small businesses through various set-aside programs. If you qualify for even one of these categories, you're competing in a dramatically smaller pool than the open market.

This guide covers every major set-aside type: what it is, who qualifies, how to get certified, and how much money flows through each program.

Overview: All Set-Aside Categories at a Glance

Program	Goal	Key Requirement	Sole-Source Limit
Small Business	23% of all contracts	Below SBA size standard	N/A (competitive)
8(a)	5% of all contracts	Socially/economically disadvantaged	$4.5M (services) / $7M (manufacturing)
SDVOSB	3% of all contracts	Service-disabled veteran owned	$4.5M (services) / $7M (manufacturing)
WOSB/EDWOSB	5% of all contracts	Women-owned (51%+)	$4.5M (services) / $7M (manufacturing)
HUBZone	3% of all contracts	Located in underutilized zone	$4.5M (services) / $7M (manufacturing)
Indian-Owned	Varies by agency	Indian Economic Enterprise or tribal	Unlimited (for some agencies)

Small Business Set-Asides

What it is

The broadest set-aside category. When a contracting officer expects at least two small businesses can perform the work, they must set the contract aside for small businesses only. Large corporations cannot compete on these contracts.

Who qualifies

Any business that falls below the SBA size standard for the contract's NAICS code. Size standards vary by industry:

• Revenue-based: Most service industries use annual revenue thresholds ($9.5M to $47M depending on NAICS code)
• Employee-based: Most manufacturing uses employee counts (500 to 1,500 employees depending on the industry)

Check your size standard at sba.gov/size-standards by entering your NAICS code.

How to qualify

No separate certification needed. When you register on SAM.gov and enter your NAICS codes, the system calculates your small business status based on your reported revenue or employee count. Self-certification.

How much money

The government-wide goal is 23% of all prime contracting dollars — roughly $178+ billion annually. This is the largest set-aside category by far.

8(a) Business Development Program

What it is

The SBA's flagship program for socially and economically disadvantaged business owners. It's a 9-year development program that provides access to set-aside contracts, mentoring, management assistance, and — most valuably — sole-source contracts up to millions of dollars with no competitive bidding required.

Who qualifies

Business owners who are:

• Socially disadvantaged: Members of designated groups (Black Americans, Hispanic Americans, Native Americans, Asian Pacific Americans, Subcontinent Asian Americans) or individuals who can demonstrate social disadvantage through a preponderance of evidence
• Economically disadvantaged: Personal net worth under $850,000 (excluding primary residence and business equity), adjusted gross income under $400,000 averaged over 3 years
• Business requirements: At least 51% owned by the disadvantaged individual, been in business for at least 2 years (with some waivers), demonstrated potential for success

How to get certified

1. Create an account on certify.sba.gov. This is the SBA's certification portal for all socioeconomic programs.
2. Complete the online application. Extensive documentation required: tax returns (personal and business, 3 years), financial statements, articles of incorporation, resumes, personal financial statement (SBA Form 413).
3. Submit and wait for review. The SBA reviews applications and may request additional documentation. Processing time is typically 90 days.
4. Annual reviews. Once certified, you submit annual reviews to maintain status. The program lasts 9 years total with no renewal.

Sole-source advantage

The biggest benefit: a contracting officer can award a contract directly to an 8(a) firm without competition, up to $4.5 million for services or $7 million for manufacturing. This means an agency can hand your business a multi-million dollar contract without any other company getting a chance to bid. No other program offers this level of direct access.

How much money

The government-wide goal is 5% of prime contracting dollars. In FY2025, over $40 billion went to 8(a) firms.

Service-Disabled Veteran-Owned Small Business (SDVOSB)

What it is

Contracts set aside for small businesses owned by veterans with service-connected disabilities. The VA is the largest user of SDVOSB set-asides, but all agencies have SDVOSB goals.

Who qualifies

• Business must be at least 51% owned by one or more service-disabled veterans
• The service-disabled veteran must control daily business operations
• The veteran's disability must be service-connected (rated by the VA)
• Business must be small under the relevant NAICS size standard

How to get certified

As of January 2023, SDVOSB certification is handled by the SBA (previously the VA handled it for VA contracts only):

1. Apply through certify.sba.gov. Submit documentation of veteran status, service-connected disability rating (VA letter), business ownership documents, and operating agreements.
2. SBA reviews and verifies. They may contact the VA to confirm disability ratings. Processing typically takes 60-90 days.
3. Maintain certification. Recertification required every 3 years.

How much money

Government-wide goal: 3% of all prime contract dollars. The VA has a higher internal goal and prioritizes SDVOSB firms heavily. FY2025 spending to SDVOSB firms exceeded $28 billion.

Women-Owned Small Business (WOSB) and Economically Disadvantaged WOSB (EDWOSB)

What it is

Contracts set aside for businesses owned and controlled by women. There are two tiers:

• WOSB: Can compete for contracts in industries where women are "substantially underrepresented"
• EDWOSB: Can compete for WOSB contracts PLUS contracts in industries where women are merely "underrepresented" — a broader pool

Who qualifies

For WOSB:

• Business at least 51% owned by one or more women who are U.S. citizens
• Women must control management and daily operations
• Business must be small under relevant NAICS size standard

For EDWOSB (additional requirements):

• All WOSB requirements, plus:
• Personal net worth under $850,000 (excluding primary residence and business equity)
• Adjusted gross income averaged over 3 years under $400,000
• Fair market value of all assets under $6.5 million

How to get certified

1. Apply through certify.sba.gov or through an SBA-approved third-party certifier (like WBENC or NWBOC).
2. Submit documentation: Business ownership documents, tax returns, articles of incorporation/organization, and for EDWOSB: personal financial statements.
3. Certification review: Processing typically takes 60-90 days through SBA.

How much money

Government-wide goal: 5% of prime contracting dollars. FY2025 WOSB spending exceeded $32 billion — consistently meeting or exceeding the goal in recent years.

HUBZone (Historically Underutilized Business Zones)

What it is

Contracts set aside for businesses located in economically distressed areas. The program encourages economic development in communities that need it by directing federal spending there.

Who qualifies

• Principal office: Must be located in a designated HUBZone (check the SBA HUBZone Map)
• Employees: At least 35% of your employees must live in a HUBZone (they don't need to work there, just live there)
• Ownership: At least 51% owned by U.S. citizens, a Community Development Corporation, an agricultural cooperative, an Indian tribe, or a Native Hawaiian organization
• Size: Must be small under the relevant NAICS size standard

How to get certified

1. Check the HUBZone map to verify your business address and employee residences qualify.
2. Apply through certify.sba.gov. Documentation includes: lease/deed for principal office, employee roster with home addresses, proof of residency for employees (utility bills, licenses), business ownership documents.
3. SBA site visit. The SBA may conduct an in-person visit to verify your office location and operations.
4. Recertification: Required every 3 years, with annual representations that you still meet requirements.

How much money

Government-wide goal: 3% of prime contracting dollars. HUBZone spending was approximately $18 billion in FY2025. This goal has historically been the hardest for the government to meet, meaning there's often more demand for HUBZone firms than supply — good odds if you qualify.

Indian-Owned Economic Enterprises and Tribal Set-Asides

What it is

Several programs support Native American-owned businesses in government contracting:

• Indian Incentive Program: Prime contractors who subcontract to Indian-owned businesses get a 5% rebate from the government
• Buy Indian Act: The Bureau of Indian Affairs (BIA) and Indian Health Service (IHS) can set aside contracts exclusively for Indian-owned businesses
• Tribal 8(a): Tribally-owned businesses can participate in the 8(a) program with some advantages (no personal net worth requirement, no 9-year limit on program participation)

Who qualifies

• Indian Economic Enterprise: At least 51% owned by one or more Indians (enrolled members of federally recognized tribes), or by a federally recognized Indian tribe
• Tribal firms (8(a)): Businesses owned by a federally recognized Indian tribe, Alaska Native Corporation, Native Hawaiian Organization, or Community Development Corporation

Key advantage for tribal 8(a) firms

Unlike individual 8(a) firms, tribal entities can own multiple 8(a) companies simultaneously, have no cap on sole-source contract values from some agencies, and are not subject to the 9-year program limit. This makes tribal 8(a) firms some of the most successful government contractors in the country.

How to get certified

For Buy Indian Act contracts: Register with the Indian Small Business Economic Enterprise (ISBEE) repository maintained by BIA. For tribal 8(a): Apply through the standard SBA 8(a) process at certify.sba.gov with tribal ownership documentation.

Stacking Certifications: Multiple Set-Asides

Here's where it gets powerful: certifications stack. A business can hold multiple set-aside certifications simultaneously. For example:

• A woman-owned business in a HUBZone can bid on WOSB set-asides AND HUBZone set-asides
• A service-disabled veteran who is also economically disadvantaged can hold both SDVOSB and 8(a) certifications
• A tribal enterprise in a HUBZone can access tribal, 8(a), AND HUBZone set-asides

Each additional certification opens a new pool of opportunities. If you qualify for multiple programs, pursue all of them.

How Contracting Officers Decide to Set Aside a Contract

Understanding the decision process helps you position yourself:

1. Market research: Before posting a contract, the contracting officer researches whether capable small businesses exist in the relevant NAICS code.
2. Rule of Two: If they expect at least two small businesses can perform the work at a fair price, the contract MUST be set aside for small businesses. This is mandatory, not optional.
3. Socioeconomic set-aside consideration: If the contract can be set aside for a specific socioeconomic group (8(a), SDVOSB, WOSB, HUBZone) AND they expect competition from at least two certified firms, they may further restrict it.
4. Agency goals: If an agency is behind on its SDVOSB goal (for example), contracting officers will actively look for SDVOSB set-aside opportunities to help meet the target.

This means visibility matters. Being registered on SAM.gov with the right NAICS codes and certifications makes you "findable" when contracting officers do market research. If they can't find you, they can't set contracts aside for businesses like yours.

Common Questions About Set-Aside Contracts

Can I bid on set-aside contracts without certification?

For small business set-asides: yes, if you self-certify as small in your SAM.gov profile. For 8(a), SDVOSB, WOSB, and HUBZone set-asides: no. You must have the relevant SBA certification active at the time of bid submission.

Are set-aside contracts smaller than full-and-open contracts?

Not necessarily. While simplified acquisitions ($10K-$250K) are automatically set aside for small businesses, there's no upper dollar limit on set-aside contracts. Multi-million and even multi-billion dollar contracts can be set aside if capable small businesses exist.

What happens if my business grows too large?

If you exceed the size standard, you "graduate" out of small business status for that NAICS code. However, contracts you've already won continue — you don't lose existing set-aside contracts midstream. You just can't bid on new set-aside opportunities for that NAICS code until/unless your size comes back down or the SBA updates the threshold.

How competitive are set-aside contracts?

Less competitive than open-market contracts — that's the whole point. Instead of competing against Fortune 500 companies, you're competing only against other small businesses (or even only against certified 8(a)/SDVOSB/WOSB/HUBZone firms). Many set-aside contracts receive only 1-3 bids.

Can I use set-aside certifications as a subcontractor?

Yes. Large prime contractors have small business subcontracting goals. Your certifications make you attractive as a subcontractor, especially for primes trying to meet their socioeconomic subcontracting requirements.

Getting Started: Which Certification Should You Pursue First?

1. Register on SAM.gov immediately. This automatically establishes your small business status. Takes 2-4 weeks to process, so don't delay.
2. Check HUBZone eligibility. This takes 5 minutes — just look up your address on the SBA map. If you qualify, it's the easiest certification with the least competition.
3. If you're a veteran with a service-connected disability: SDVOSB certification is straightforward if you have your VA disability letter. Apply immediately.
4. If you're a woman business owner: WOSB is relatively quick. EDWOSB opens more doors if you meet the economic thresholds.
5. If you're socially and economically disadvantaged: 8(a) takes the longest but offers the most powerful benefits (sole-source contracts). Start the process even as you pursue other certifications.
6. Search FedScanner for set-aside contracts in your NAICS codes. See what's out there before you start bidding. Understand the competition and opportunity volume in your specific market.
