WOSB and EDWOSB Certification: How Women-Owned Small Businesses Win Federal Contracts

A WOSB is a women-owned small business: a small business at least 51% owned and controlled by women who are U.S. citizens. Through the Small Business Administration's (SBA) Women-Owned Small Business Federal Contract Program, agencies can set aside contracts for certified WOSBs in 626 industries, and for economically disadvantaged women-owned small businesses (EDWOSBs) in 107 more. SBA certification is free, and since October 15, 2020 it has been required to win these set-asides.

WOSB vs. EDWOSB: what's the difference?

Both statuses come from the same SBA program, and both need SBA certification. EDWOSB is a subset of WOSB for owners who also meet economic limits. "An EDWOSB automatically qualifies as a WOSB," so an EDWOSB can compete for both kinds of set-asides.

Being women-owned doesn't make a business "disadvantaged." WOSB has no disadvantage test at all. EDWOSB uses only economic tests, so it isn't the same as the 8(a) program or the small disadvantaged business category.

WOSB certification requirements

The rules are in 13 CFR Part 127. Your business must meet all of these:

• Small. Under the SBA size standard for a NAICS code in your SAM.gov profile, and under the size standard of each contract you bid on. See who can get government contracts to check your size.
• Owned by women. At least 51%, "unconditionally and directly."
• Controlled by women. Women run both the long-term decisions and the day-to-day management.
• U.S. citizens who live in the U.S. The rule says "citizens of and reside in the United States." Permanent residents (green card holders) don't count as citizens.
• In good standing. No active exclusion in SAM.gov, and no unresolved federal debts, such as tax liens or loan defaults, unless you're current on an approved repayment plan.

What "owned" means

• Directly. Ownership through another company, a trust or an employee stock ownership plan doesn't count. The exception is a revocable living trust where the woman is the grantor, the trustee and the sole current beneficiary.
• Corporations: women own 51% of each class of voting stock and 51% of all stock.
• LLCs and partnerships: women own 51% of each class of membership or partnership interest.
• Stock options: options held by men or other entities are treated as if they'd been exercised.
• Profits: the women owners must get at least 51% of any profit distribution.
• Community property doesn't matter. SBA determines ownership "without regard to community property laws," so a husband's community property claim doesn't cut into her ownership.

What "controlled" means

This is where most applications run into trouble.

• A woman holds the highest officer position, usually President or CEO, and has the management experience to run the business.
• She works in the business full time. If she works fewer hours than the business's normal hours, SBA will assume she doesn't control it unless the business shows otherwise.
• She doesn't have to hold the license. But if a man holds the required license and also owns part of the business, SBA may find that he controls it.
• Women control the board, or serve as the managing members of an LLC.
• Men can be involved, but can't be in charge. A husband, partner or former employer can't exercise actual control, provide critical financing, bonding or a critical license, or earn more than the top woman officer unless the pay is commercially reasonable.

EDWOSB requirements: the economic limits

Each woman claiming economic disadvantage must meet all three tests in 13 CFR 127.203. They're the same limits the 8(a) program uses, and they haven't changed since 2022.

That last row trips people up. The home and the business are left out of net worth, but they're counted in the total asset test.

A few more rules:

• Spouses. A married owner must submit her spouse's financial information separately. SBA looks at the spouse's finances when the spouse has a role in the business or has lent it money or guaranteed its loans.
• Recent transfers. Assets she gave to an immediate family member in the two years before applying count as hers, with exceptions for things like education, medical care and gifts for special occasions.
• Income over $400,000 creates a presumption, not an automatic denial. A one-time event, like selling property, can be explained.

You'll see older numbers online, such as $750,000 in net worth or $6 million in assets. Those are out of date. Use the regulation.

How to get WOSB certified, step by step

1. Check that your NAICS codes are on SBA's list. If your main codes aren't, certification won't open set-asides in them. See the industries section below.
2. Get your SAM.gov registration active and current. SBA shows your certification in SAM.gov, and you'll need an active registration to bid anyway. See how to register on SAM.gov.
3. Gather your documents. Expect to provide proof of citizenship, ownership and governing documents (articles, operating agreement or bylaws, stock records), and business and personal financial records, including signed tax returns and bank statements. EDWOSB applicants also provide personal financial information, including the spouse's.
4. Apply at certifications.sba.gov. It's free. The majority woman owner must take responsibility for the accuracy of everything submitted.
5. Answer SBA's questions quickly. If you don't send information SBA asks for, it may presume the missing information would hurt your eligibility.
6. Wait for the decision. SBA says it will decide "within ninety (90) calendar days after receipt of a complete package, whenever practicable." It won't process incomplete applications. SBA hasn't published an average processing time for WOSB.

If you're denied, you can reapply 90 calendar days after the decision.

Third-party certifiers

SBA also accepts certification from four approved third-party certifiers:

• El Paso Hispanic Chamber of Commerce
• National Women Business Owners Corporation
• U.S. Women's Chamber of Commerce
• Women's Business Enterprise National Council (WBENC)

They may charge a fee, but they must tell you in writing first that SBA's certification is free. Even with third-party approval, you still need to upload your proof of citizenship and certification documents to SBA's portal before you can bid on WOSB set-asides.

Two other routes exist. A women-owned business already certified by SBA as a veteran-owned or service-disabled veteran-owned small business can use that certification (see SDVOSB and veteran-owned business contracts). And a woman-owned 8(a) participant qualifies as an EDWOSB.

How long does WOSB certification last?

Certification lasts three years at a time. To keep it, you go through a program examination before the three years run out.

• Every three years, a certified WOSB or EDWOSB must go through a program examination. You must recertify (or tell SBA you finished a third-party exam) in the 90 calendar days before your eligibility period ends. If you miss it, SBA decertifies you when the period ends, but reinstates you if you recertify within 30 days after.
• Report changes within 30 days. Changes in ownership, structure or management must go to SBA within 30 calendar days.
• No annual attestation for now. SBA's page says annual attestation "is currently in abeyance." Check your renewal date in the certification portal, because SBA has extended some renewal dates.
• SBA can review you at any time, including site visits.

In June 2026, government contracting advisers, including the law firm Thompson Hine and the accounting firm BDO, reported that SBA had begun program examinations of EDWOSB participants, asking for tax returns and detailed questions about each owner's finances. SBA hadn't announced results as of October 10, 2026. If you're an EDWOSB, keep your personal financial records organized and current.

Which contracts can be set aside for WOSBs?

Only contracts in industries where SBA has found women-owned businesses are underrepresented. The current list took effect October 1, 2022 and has 733 NAICS codes:

• 626 codes where agencies can set aside work for all WOSBs (EDWOSBs can compete too).
• 107 codes where agencies can set aside work only for EDWOSBs.

Download the full list from SBA's eligible NAICS page. SBA must restudy the industries every five years.

How set-asides and sole-source awards work

• Set-asides are optional. A contracting officer "may" set aside a contract above the micro-purchase threshold for WOSBs or EDWOSBs when market research shows that two or more will offer at a fair and reasonable price. That's different from general small business set-asides, which are required when the rule of two is met.
• No pecking order. Above the simplified acquisition threshold, there's no order of precedence among the 8(a), HUBZone, SDVOSB and WOSB programs.
• Sole-source awards are allowed up to $8.5 million in manufacturing NAICS codes and $5.5 million in other codes under the FAR, when only one WOSB is expected to offer. SBA's own regulation still shows older, lower figures, but contracting officers follow the FAR. Sole-source awards require full certification.
• Limits on subcontracting apply at any dollar value. On services, for example, you can't pay more than 50% of the contract amount to subcontractors that aren't similarly situated. Certified WOSB subcontractors count on your side. See limitations on subcontracting.
• Be certified before you bid. The codified FAR and SBA's rule let a business with a complete pending application compete for a set-aside. The FAR overhaul text that many agencies have adopted says the contracting officer must verify certified status before award, and has no pending-application route.

Where WOSB set-asides actually come from

In FY2026, agencies posted 4,047 WOSB and EDWOSB set-aside solicitations on SAM.gov, counted once per notice, by FedReady's count. That's 2.7% of all solicitations. The Defense Logistics Agency posted 3,732 of them (92%), mostly for manufactured parts. Outside DLA, there were only 315 across the whole year, led by other Defense Department offices and the Department of the Interior. The most common codes outside DLA were janitorial services, commercial building construction, engineering services, machinery repair and landscaping.

On October 10, 2026, FedReady's search of SAM.gov data showed 36 open WOSB and EDWOSB set-aside notices.

How much do women-owned small businesses win?

The government's goal is to award at least 5% of contract dollars to women-owned small businesses each year. In FY2025, they won $29.4 billion in prime contracts, or 4.52%, according to SBA's scorecard. The government missed the 5% goal every year from FY2020 through FY2025. The number of women-owned small businesses winning prime contracts fell 7.4%, to 11,648.

Here's the part most guides leave out: only about $2 billion in new awards came through WOSB and EDWOSB set-asides ($1.98 billion, 6% of it sole source), a small slice of the $29.4 billion total. Most of the money went to women-owned firms through regular small business set-asides and open competition.

That's possible because certification is needed only for WOSB set-asides and sole-source awards. A women-owned small business that doesn't seek those contracts can still self-certify as women-owned in SAM.gov, win other contracts, and count toward an agency's women-owned goal.

Women-owned firms also did well as subcontractors: $16.3 billion, or 5.67% of subcontract dollars in FY2025, above the 5% subcontracting goal. See how to become a government subcontractor.

Two large contract vehicles have women-owned pools. GSA's OASIS+ professional services program includes a women-owned small business contract, and GSA's Polaris IT contract has a WOSB pool. See IDIQ contracts explained for how these vehicles work.

WOSB vs. WBE and other women-owned certifications

Many women-owned businesses hold more than one certification. Only some of them count for federal set-asides.

WBENC appears twice because it issues its own WBE certification and is also one of SBA's approved WOSB certifiers. Ask them which one you're applying for. And SBA notes that WOSB certification benefits apply only to federal contracts, not private-sector work.

Common WOSB mistakes

• Self-certifying for a set-aside. That ended October 15, 2020. You need SBA or an approved certifier.
• Bidding outside the NAICS list. A WOSB set-aside can only be in a listed code. If your trade isn't listed, certification won't help you win set-asides in it.
• A part-time owner. If the woman owner works another full-time job, SBA will assume she doesn't control the business.
• A man holds the license and some of the equity. SBA may find that he controls the business.
• Looking for "WOSB grants." WOSB is a contracting program. SBA says it "does not provide grants for starting and expanding a business."
• Paying someone to get certified. SBA's certification is free. You don't need a paid service to apply.

Free help and next steps

• Women's Business Centers. SBA funds more than 100 of them, offering "free, to low-cost counseling and training."
• APEX Accelerators help with certification and bidding at no cost.
• SBA's certification help desk: certifications@sba.gov or 866-722-4357 (866-SBA-HELP).
• Compare all four programs in set-aside contracts explained.
• Pick the right industry codes in how to choose NAICS codes.
• Start finding work in how to find government contracts.
