Small Business Set-Asides: Finding Federal Contract Opportunities
Published 2026-02-16
The federal government is the largest buyer of goods and services in the world, and it has a statutory goal of awarding at least 23% of prime contract dollars to small businesses. Set-aside contracts are one of the primary mechanisms for achieving this — and they represent a massive opportunity for qualifying firms.
What Are Set-Aside Contracts?
A set-aside restricts competition for a federal contract to a specific category of small business. Instead of competing against large prime contractors, small businesses compete only against other qualifying firms. The main set-aside categories are:
- Small Business (SB): The broadest category. Size standards vary by NAICS code — typically based on average annual revenue or employee count.
- 8(a) Business Development: For socially and economically disadvantaged small businesses. Participants can receive sole-source contracts up to $4.5M (services) or $7M (manufacturing).
- HUBZone: For firms located in Historically Underutilized Business Zones. Offers a 10% price evaluation preference on full-and-open competitions.
- SDVOSB: Service-Disabled Veteran-Owned Small Business. The VA has particularly strong SDVOSB programs.
- WOSB/EDWOSB: Women-Owned Small Business and Economically Disadvantaged Women-Owned Small Business. Available in industries where women are underrepresented.
Finding Set-Aside Opportunities Through Expiring Contracts
One of the best strategies for small businesses is to identify expiring set-aside contracts. When a set-aside contract expires, the agency typically needs to re-compete it under the same set-aside designation. This creates a predictable pipeline of opportunities.
Here's how to use ContractCliff for this:
- Browse NAICS codes in your service area to find contracts in your industry.
- Look for contracts with set-aside types matching your certifications.
- Check the contract cliff dates — contracts expiring in 12-18 months are the sweet spot for capture planning.
- Search the incumbent company to understand their contract portfolio, size, and concentration. A highly concentrated incumbent may be stretched thin.
Size Standards and NAICS Codes
Your eligibility for small business set-asides depends on the NAICS code assigned to each contract. The SBA sets size standards per NAICS code — for example:
| NAICS Code | Industry | Size Standard |
|---|---|---|
| 541511 | Custom Computer Programming | $34M revenue |
| 541512 | Computer Systems Design | $34M revenue |
| 541519 | Other Computer Related Services | $34M revenue |
| 541330 | Engineering Services | $25.5M revenue |
| 561210 | Facilities Support Services | $47M revenue |
Check the SBA size standards table for your specific NAICS code.
Tips for Winning Set-Aside Recompetes
- Start early: Begin capture activities 12-18 months before the contract expires. Attend agency industry days and request meetings with the program office.
- Build past performance: If you don't have federal past performance, consider subcontracting first or pursuing smaller contracts (under $250K) through simplified acquisitions.
- Team strategically: Mentor-protege and joint venture arrangements let you combine capabilities while maintaining small business eligibility.
- Monitor SAM.gov: Set up saved searches for your NAICS codes and set-aside types to catch new opportunities as they post.
- Track the incumbent: Use ContractCliff to monitor the incumbent's full contract portfolio. If they're growing past the size standard, the next recompete may be more competitive.
Getting Started
Start by searching for companies in your space to see what contracts exist, who holds them, and when they expire. Then browse by NAICS code to map the competitive landscape in your industry.
