Quick Answer: What Are Small Business Set-Asides?

Set-asides are government contracts reserved exclusively for small businesses. The federal government aims to award 23% of prime contract dollars to small businesses, with additional goals for specific categories: 8(a) businesses, HUBZone firms, Service-Disabled Veteran-Owned Small Businesses (SDVOSB), and Women-Owned Small Businesses (WOSB). If you qualify, set-asides dramatically reduce competition and can be your fastest path to winning government contracts.

What Are Set-Asides?

Set-asides are a procurement strategy where the government reserves contracts for specific categories of small businesses. Only businesses meeting eligibility criteria can compete, significantly reducing the competitive field.

Types of Set-Asides

Total Set-Aside

100% of the contract is reserved for small businesses. Only eligible small businesses can compete.

Partial Set-Aside

Part of the contract is reserved for small businesses while the remainder is open to all competitors.

Sole Source

Contract awarded to a specific small business without competition, subject to dollar thresholds and requirements.

Why Set-Asides Exist

  • Economic Development: Small businesses drive innovation and job creation
  • Fair Competition: Levels the playing field against large corporations
  • Supply Base Diversity: Reduces government reliance on few contractors
  • Socioeconomic Goals: Supports disadvantaged and underrepresented groups
  • Congressional Mandate: Required by Small Business Act

Eligibility Requirements

Each set-aside program has specific eligibility requirements. You must meet all requirements and maintain compliance throughout contract performance.

Universal Small Business Requirements

Meet SBA size standard for your NAICS code
Organized for profit and located in the US
Independently owned and operated
Not dominant in field of operation
Registered in SAM.gov

Affiliation Rules

SBA looks at "affiliates" when determining size. Affiliated businesses are combined for size determination purposes:

  • Stock Ownership: Entity owning 50%+ of another
  • Common Management: Shared officers or directors
  • Identity of Interest: Close relatives with businesses
  • Newly Organized Concerns: Spin-offs from large businesses
  • Joint Ventures: Partners may be affiliates

Self-Certification Warning

For basic small business set-asides, you self-certify in SAM.gov. But misrepresentation of small business status is a serious federal offense with civil and criminal penalties. SBA conducts size protests and compliance reviews.

Rule of Two

The "Rule of Two" determines when contracting officers must set aside a procurement for small businesses.

How Rule of Two Works

A contracting officer must set aside a procurement for small businesses if there is a reasonable expectation that:

1

Two or More Small Businesses

At least two responsible small businesses will submit offers

2

Fair and Reasonable Price

Award can be made at a fair and reasonable price

Set-Aside Priority

When multiple set-aside programs could apply, there's a general order of consideration:

  1. 1. 8(a) competitive or sole source
  2. 2. HUBZone set-aside
  3. 3. SDVOSB set-aside
  4. 4. WOSB/EDWOSB set-aside
  5. 5. Small business set-aside
  6. 6. Full and open competition

Simplified Acquisition Threshold

Acquisitions under the SAT (currently $250,000) are automatically reserved for small businesses unless the contracting officer cannot find two capable small business offerors.

Sole Source Awards

Sole source awards allow the government to award contracts without competition to qualified small businesses—the ultimate competitive advantage.

Sole Source Thresholds

ProgramServicesManufacturing
8(a)$4.5 million$7 million

Where to Search

SAM.gov

Primary source for federal contract opportunities. Filter by set-aside type.

Agency Forecast

Many agencies publish procurement forecasts showing upcoming set-asides.

SubNet (SBA)

Find subcontracting opportunities with large prime contractors.

OSDBU Offices

Agency small business offices provide matchmaking and forecast info.

Winning Strategies

Even with reduced competition, you still need strong strategies to win set-aside contracts consistently.

Start with Smaller Contracts

Build past performance on micro-purchases and simplified acquisitions before pursuing larger set-asides. Track record matters even in set-aside competitions.

Build Agency Relationships

Meet with OSDBU representatives, attend industry days, and respond to RFIs. Agencies prefer contractors they know and trust.

Get Multiple Certifications

If you qualify for multiple programs (e.g., WOSB + HUBZone), get certified in all of them to maximize opportunities.

Focus Your NAICS Codes

Concentrate on NAICS codes where you're most competitive and where set-asides are most common. Depth beats breadth.

Consider Mentor-Protégé

Partner with a mentor to access their resources, past performance, and joint venture opportunities on larger contracts.

Common Mistakes

Not Getting Certified

Many businesses qualify for programs like 8(a) or WOSB but never apply. If you might qualify, investigate—the benefits are substantial.

Passive Marketing

Just being certified isn't enough. You must actively market to agencies, attend events, and pursue relationships—especially for sole source opportunities.

Exceeding Size Standards

Growing businesses must monitor their size. Losing small business status unexpectedly eliminates set-aside eligibility. Plan your growth strategically.

Subcontracting Violations

Set-aside contracts have limits on subcontracting. Violating these rules can result in termination, debarment, and False Claims Act liability.

Ignoring Recertification

Certifications require periodic recertification. Mark deadlines and maintain documentation. Lapsed certifications mean lost opportunities.

Frequently Asked Questions

Can I compete for set-asides in multiple categories?

Yes, if you qualify. A business can be 8(a), HUBZone, and WOSB simultaneously if it meets all requirements. Each certification expands your opportunity pool.

What happens if I grow too large during a contract?

Size status is generally determined at time of offer. If you grow during performance, you can usually complete the contract. However, you may need to recertify for options or follow-on contracts.

How long does certification take?

8(a) certification takes 60-90 days on average. HUBZone takes 30-60 days. WOSB and SDVOSB through SBA typically take 15-30 days. Start early and have all documentation ready.

Can I protest a set-aside award?

Yes. You can file a size protest with SBA if you believe the winner doesn't meet size standards, or a status protest if you believe they don't meet certification requirements. Protests must be filed within 5 days of award.

Do set-asides pay less than full and open contracts?

No. Set-asides must still be awarded at fair and reasonable prices. The government doesn't expect discounts for set-asides. Price your work to be profitable and competitive within the set-aside pool.
