WOSB and EDWOSB: Women-Owned Small Business Federal Contracting Guide

The federal government has a statutory goal of awarding 5% of all prime contract dollars to women-owned small businesses (WOSBs) each year. In FY2024, actual awards to WOSBs reached approximately $28 billion — a record, but still short of the 5% statutory goal. That gap represents real opportunity for certified women-owned businesses.

The WOSB Program (and its subset, the EDWOSB — Economically Disadvantaged WOSB program) gives qualifying firms access to set-aside contract competitions restricted to women-owned businesses only.

WOSB vs. EDWOSB: What's the Difference?

The WOSB Program has two tiers:

WOSB set-asides are restricted to industries where women-owned businesses are "substantially underrepresented" based on SBA data. The SBA publishes a list of eligible NAICS codes for WOSB set-asides.

EDWOSB set-asides can be used for any NAICS code in the program — a broader opportunity base.

If you qualify for EDWOSB, you automatically qualify for WOSB as well (EDWOSB is a subset). Most firms with genuine economic disadvantage will pursue EDWOSB to access the larger opportunity pool.

WOSB Eligibility Requirements

For Both WOSB and EDWOSB:

1. Small business: Must qualify as small under the SBA size standard for the relevant NAICS code.
2. 51% women ownership: The business must be at least 51% unconditionally owned by one or more women who are US citizens.
3. Women management control: Women must hold the highest management position and control day-to-day operations. A man cannot be the CEO while a woman is listed as the owner — the woman must genuinely run the company.
4. US citizenship: The qualifying women owners must be US citizens.

Additional EDWOSB Requirements:

The qualifying woman/women must be economically disadvantaged:

• Personal net worth (excluding equity in primary residence and business) ≤ $850,000
• Total assets ≤ $6 million (including business and personal assets)
• Adjusted gross income (three-year average) ≤ $400,000

How to Get WOSB/EDWOSB Certified

Since October 2020, the SBA is the exclusive certifying authority for WOSB and EDWOSB status. The old self-certification option (where you simply checked a box in SAM.gov) no longer qualifies for set-aside contracts. You must now receive certification from the SBA or an approved third-party certifier.

SBA Direct Certification (Free)

The SBA certifies WOSB and EDWOSB status through the certify.sba.gov platform at no cost.

Timeline: The SBA has 90 days to approve or deny a complete application. In practice, reviews often take 2–5 months.

Required documents:

• Proof of US citizenship (birth certificate, passport, or naturalization certificate)
• Articles of incorporation/organization
• Operating agreement or bylaws
• Stock ledger or member ledger showing 51%+ women ownership
• Business licenses
• Three years of personal tax returns (for EDWOSB economic disadvantage determination)
• Personal financial statement (for EDWOSB)
• Resume or biography of the qualifying woman owner(s)

Third-Party Certification (Paid)

The SBA also accepts certifications from approved third-party certifiers:

• Women's Business Enterprise National Council (WBENC) — widely accepted for commercial certification; also accepted for WOSB
• National Women Business Owners Corporation (NWBOC)
• US Women's Chamber of Commerce (USWCC)
• El Paso Hispanic Chamber of Commerce

Third-party certification typically costs several hundred dollars and requires the same documentation. The advantage is that WBENC certification is widely recognized in commercial supply chains and in federal contracting — giving you dual-market certification value.

Which NAICS Codes Are Eligible for WOSB Set-Asides?

WOSB set-asides are only available in NAICS codes where the SBA has determined women-owned businesses are underrepresented. This is a specific list — not all NAICS codes qualify.

As of the most recent SBA list, eligible industries include:

• Certain construction trades
• Some professional services (management consulting, market research)
• Healthcare support services
• Certain manufacturing categories
• Educational support services
• Certain IT services

EDWOSB set-asides are available in all NAICS codes where women-owned businesses are "underrepresented OR substantially underrepresented" — a broader category than pure WOSB.

Before pursuing WOSB set-asides, verify your primary NAICS codes are on the eligible list. The SBA publishes the current list at sba.gov.

Contracting Thresholds for WOSB Set-Asides

Contracting officers may set aside contracts for WOSB or EDWOSB competition when:

1. The NAICS code is eligible
2. There are at least two certified WOSB/EDWOSB firms that are likely to submit competitive offers
3. The contract is expected to be reasonable in price

Sole-source awards are available for WOSB and EDWOSB, subject to dollar thresholds:

• WOSB sole-source: Up to $4.5 million for services/goods; $7 million for manufacturing
• EDWOSB sole-source: Same thresholds as WOSB

These sole-source thresholds are identical to 8(a) thresholds — and in practice, contracting officers use WOSB sole-source authority less frequently than 8(a) sole-source authority. Building a relationship with the contracting officer before the requirement is defined is critical to getting a WOSB sole-source award.

Maintaining Your WOSB/EDWOSB Certification

Annual Review

SBA-certified WOSBs must submit an annual review demonstrating continued eligibility — same ownership structure, same management control, still a small business.

Three-Year Recertification

Every three years, you must resubmit documentation for a full recertification review.

Reporting Changes

You must notify the SBA within 30 days of any change in ownership, management, or business structure that could affect eligibility. This includes:

• Adding a new partner or investor who changes the ownership calculation
• A change in the CEO or managing member
• Any transfer of more than 50% of ownership

Size Recertification for Contracts

Before each 8(a), WOSB, or other small business set-aside contract award, the agency typically requires you to recertify your small business size status under the relevant NAICS code.

Strategy: Maximizing Your WOSB/EDWOSB Status

Target EDWOSB If You Qualify

EDWOSB opens more set-aside pools than WOSB alone. If you meet the economic disadvantage criteria, pursue EDWOSB certification — it is more valuable.

Combine with Other Certifications

WOSB/EDWOSB status can coexist with:

• 8(a) certification — Many 8(a) firms are also WOSB/EDWOSB certified. This gives access to three set-aside pools.
• HUBZone — A WOSB in a HUBZone area can compete for WOSB set-asides and receive the 10% price preference in open competitions.
• SDVOSB/VOSB — Women veterans can hold both WOSB and SDVOSB certifications simultaneously.

Target Agencies with WOSB Award Track Records

Some agencies consistently exceed their WOSB goals:

• Department of Defense (Army Corps of Engineers)
• Department of Agriculture
• Department of Health and Human Services
• General Services Administration

Use USASpending.gov to identify agencies awarding in your NAICS codes under WOSB set-asides.

Build Your Capability Statement Around Women-Owned Status

Your capability statement should explicitly state your WOSB or EDWOSB certification and which NAICS codes it applies to. Agency small business specialists are actively looking to meet their WOSB spending goals — make it easy for them to find you.

Common WOSB/EDWOSB Mistakes

1. Self-certifying instead of getting SBA certification: Post-2020, self-certification does not qualify for set-aside contracts. You need formal SBA or third-party certification.

2. Male family member controls the business in practice: If your husband or brother makes the real business decisions even though you hold 51% on paper, the SBA will find this in their review and deny or revoke certification.

3. Not updating the SBA when ownership changes: Adding a male partner who becomes a 50/50 co-owner is an automatic disqualifier. Notify the SBA before any change that could affect eligibility.

4. Pursuing WOSB set-asides in non-eligible NAICS codes: Not all NAICS codes are on the WOSB-eligible list. Using WOSB set-aside authority for a non-eligible code is a violation.

Key Takeaways

• WOSB requires 51%+ women ownership and management control — paper-only ownership does not qualify.
• EDWOSB adds an economic disadvantage test (net worth ≤$850K, assets ≤$6M, income ≤$400K avg) but opens all NAICS codes for set-asides.
• SBA certification is now required for set-aside contracts — self-certification is no longer valid.
• Sole-source authority exists up to $4.5M — use it by building relationships before requirements are formally defined.
• WOSB set-asides are NAICS-code-limited — verify your codes are on the eligible list before pursuing these contracts.
• Stacking certifications (WOSB + 8(a), WOSB + HUBZone) maximizes the number of set-aside pools available to you.
