The Woman-Owned Small Business (WOSB) and Economically Disadvantaged WOSB (EDWOSB) programs let agencies reserve federal contracts for firms that are at least 51% owned and controlled by women who are U.S. citizens. The mechanics changed in 2020: self-certification was eliminated, so you now need a formal certification before you can win a WOSB or EDWOSB set-aside. And there’s a catch that trips up a lot of IT firms — set-asides only apply in the NAICS codes the SBA has specifically designated. This guide walks the eligibility, the certification path, and the NAICS limit, written from a SAM-active IT contractor’s chair. It’s educational, not legal advice — verify every detail against SBA and the solicitation.
WOSB vs. EDWOSB: two tiers, one ownership test
Both start from the same ownership rule. EDWOSB adds a financial layer on top.
A WOSB is a small business (under its NAICS size standard) that is at least 51% directly and unconditionally owned by one or more women who are U.S. citizens, and whose management and daily operations are controlled by one or more of those women. EDWOSB is the narrower tier: every qualifying woman must also be economically disadvantaged.
Woman-owned, woman-controlled
Ownership must be 51%+, direct, and unconditional — no options, agreements, or arrangements that could erode it. Control means a woman holds the highest officer position and runs day-to-day operations. The firm must also be small under the size standard for the contract’s NAICS code.
Adds an economic-disadvantage test
Each woman claiming disadvantage must meet personal financial limits. Per 13 CFR 127.203: 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. Certain items — like retirement accounts, your equity in your primary residence, and your ownership interest in the firm — are treated specially. Verify the current figures and exclusions against the eCFR.
Certification is no longer optional
Self-certification was eliminated. You must be certified before you can be awarded a WOSB or EDWOSB set-aside.
This is the single biggest thing firms get wrong. For years you could self-certify in SAM and pursue WOSB work. That ended. Effective October 15, 2020, the SBA removed the self-certification option — a formal certification is now a prerequisite for any WOSB or EDWOSB set-aside or sole-source award.
SBA certification (free)
Apply directly through the SBA at certifications.sba.gov (MySBA Certifications). There’s no government fee. You upload proof of citizenship, ownership, and control — and, for EDWOSB, financial documentation. Budget time for document prep.
SBA-approved third-party certifier
You can certify through an SBA-approved national certifying entity instead. These TPCs may charge a fee. If you go this route, you still submit your TPC certification and proof of citizenship to the SBA when you participate.
Already 8(a)-certified?
An active SBA 8(a) certification can streamline EDWOSB certification, because 8(a) already establishes economic disadvantage and the ownership records overlap. (The SBA will also accept VOSB/SDVOSB certification as supporting documentation, though veteran status doesn’t itself establish women’s ownership or disadvantage.) Confirm the current crosswalk with the SBA before you rely on it.
Set-asides only apply in designated NAICS codes
Being a certified WOSB doesn’t make every contract a WOSB opportunity. The code has to be on the SBA’s designated list.
Even with a clean certification, you can only win a WOSB or EDWOSB set-aside in industries the SBA has formally designated. The SBA studies which industries women are underrepresented in and publishes a list of qualifying NAICS codes — and it splits them into two buckets.
| Designation | What it means | Who can win the set-aside |
|---|---|---|
| WOSB-eligible | Industry where WOSBs are substantially underrepresented | Any certified WOSB (and EDWOSBs) |
| EDWOSB-eligible | Industry where WOSBs are underrepresented | Only certified EDWOSBs |
Many IT and software NAICS codes are on the designated list, but not all are, and the buckets matter — a code might be open to EDWOSBs only. Before you build a capture strategy around a WOSB set-aside, check your specific NAICS code against the current SBA designated-NAICS list. Our primer on NAICS codes for IT contractors covers how to pick and verify the right code; the broader landscape is in our guide to federal set-aside programs.
A clean WOSB/EDWOSB readiness check
Run this before you chase a single set-aside. It saves a lot of wasted bids.
- Confirm “small” under the size standard for the contract’s NAICS code.
- Confirm 51%+ direct, unconditional ownership by U.S.-citizen women, with a woman in control of operations.
- For EDWOSB, run the financials against the current 13 CFR 127.203 limits for every woman claiming disadvantage.
- Get certified — SBA (free) or an SBA-approved third-party certifier — before you rely on a set-aside.
- Match your NAICS to the SBA designated list and note whether it’s WOSB- or EDWOSB-only.
- Keep SAM, your application, and your bid consistent so a status protest finds nothing to grab.
