WOSB Certification: How Women-Owned Small Businesses Qualify

What Is a WOSB Set-Aside and Why Does It Matter?

Federal agencies are required by law to set aside a portion of their contracting dollars for specific categories of small businesses. WOSB set-asides are contracts that only certified women-owned small businesses can compete for — meaning your competition is dramatically smaller than in the open market.

Set-aside contracts exist in hundreds of industries across virtually every federal agency. If your business qualifies, pursuing WOSB set-asides is one of the fastest ways to build a federal contracting track record.

WOSB vs. EDWOSB — What Is the Difference?

There are two tiers of women-owned business certification in the federal system:

EDWOSB status requires demonstrating that the woman owner is economically disadvantaged — meaning her personal net worth, income, and assets fall below thresholds set by the SBA. As of 2026 those limits are a personal net worth under $850,000, adjusted gross income of $400,000 or less averaged over the prior three years, and personal assets of $6.5 million or less. (The SBA updates these figures periodically — always confirm the current limits at certifications.sba.gov.) This is similar in concept to the 8(a) program's economic disadvantage requirements. EDWOSB firms can compete for both EDWOSB-specific set-asides and general WOSB set-asides.

Who Qualifies for WOSB Certification?

To be certified as a WOSB, your business must meet all of the following criteria:

• At least 51% owned by one or more women who are U.S. citizens
• The business must be controlled and managed by one or more of those women — meaning a woman must hold the highest officer position and be involved in daily management decisions
• The business must qualify as a small business under SBA size standards for its primary NAICS code
• The business must be for-profit

How to Apply for WOSB Certification

There are two ways to get certified: through the SBA directly, or through an SBA-approved third-party certifier.

Option 1: SBA Direct Certification (Free)

The SBA offers free WOSB certification through its online portal at certify.sba.gov. This is the most common route for small businesses. Here is what the process looks like:

1. Create an account at certify.sba.gov using your business email.
2. Complete your business profile — legal name, EIN, SAM.gov UEI, primary NAICS code, and basic business information.
3. Upload required documents — these typically include articles of incorporation or organization, operating agreement or bylaws showing ownership percentages, birth certificate or passport for the qualifying woman owner, and any applicable licenses or certifications.
4. Submit your application and wait for an SBA reviewer to process it. Processing times vary but the SBA aims to complete reviews within 90 days.
5. Respond to any requests for additional information. The SBA may ask for clarifying documentation.
6. Once approved, your WOSB status appears in SAM.gov and becomes searchable by contracting officers.

Option 2: Third-Party Certifiers

The SBA also approves private organizations to certify WOSB status. These certifiers may charge a fee, but some businesses prefer them for their experience in preparing applications and their established processes. SBA-approved third-party certifiers include organizations such as the Women's Business Enterprise National Council (WBENC) and El Paso Hispanic Chamber of Commerce, among others.

Check the current list of approved certifiers at sba.gov before engaging any third party.

Documents You Will Need

Gather these before you start your application to avoid delays:

• Proof of U.S. citizenship for the qualifying woman owner (birth certificate, passport, or naturalization certificate)
• Articles of incorporation, articles of organization, or partnership agreement showing ownership structure
• Operating agreement or corporate bylaws showing ownership percentages and management roles
• Proof of business licenses and good standing in your state
• Documentation of the woman owner's role in daily management (such as a resume, signed statement, or organizational chart)
• For EDWOSB only: personal financial statements, tax returns, and documentation of assets and liabilities

Maintaining Your Certification

WOSB certification does not last forever. Here is what you need to know about keeping it active:

• You must recertify annually through certify.sba.gov to confirm you still meet all eligibility requirements.
• You must notify the SBA within 30 days of any change that could affect your eligibility — such as a change in ownership, management, or if you exceed SBA size standards.
• Your SAM.gov registration must also remain active and current. An expired SAM.gov registration disqualifies you from competing on set-asides regardless of your certification status.

Frequently Asked Questions

Can I self-certify as a WOSB?

No, not for set-aside contracts. As of October 15, 2020, self-certification is no longer accepted for competing on WOSB or EDWOSB set-asides. You must have certification from the SBA or an approved third-party certifier. However, you can still identify your business as women-owned in SAM.gov and on marketing materials without formal certification.

Does WOSB certification help with non-set-aside contracts?

Yes. Many prime contractors are actively looking for WOSB subcontractors to help meet their own small business subcontracting goals. WOSB certification makes your business more attractive as a subcontractor even on contracts that are not formally set aside.

What if my business grows and exceeds the small business size limit?

You must notify the SBA and you will no longer be eligible for WOSB set-asides for new contracts. However, contracts already awarded generally allow you to complete the work even if you later exceed size standards — check the specific contract terms.

Can a business have both WOSB and 8(a) certification?

Yes. Many businesses hold multiple small business certifications simultaneously. WOSB, 8(a), HUBZone, and SDVOSB are all separate programs with separate eligibility requirements. Holding multiple certifications can significantly expand your set-aside opportunities.
