What are the certification requirements for 8(a), HUBZone, SDVOSB, and WOSB programs, compared side by side?

Details / How it works

The four socioeconomic certification programs—8(a) Business Development, HUBZone, SDVOSB (VetCert), and WOSB—are administered by the U.S. Small Business Administration (SBA) and governed by FAR Part 19 and their respective CFR parts (13 CFR 124, 126, 128, and 127). All four programs require the firm to be small under its NAICS size standard. Applications are submitted through the SBA Certifications portal at certifications.sba.gov. There is no order of precedence among the programs (FAR 19.203), and a firm can hold multiple certifications simultaneously if it meets each program's eligibility conditions.

Each program targets a different basis: 8(a) focuses on social and economic disadvantage, HUBZone on geographic location in historically underutilized business zones, SDVOSB on service-disabled veteran status, and WOSB on women ownership. Certification processes vary: 8(a) requires a complete application processed within 90 days; HUBZone requires recertification every three years; WOSB requires certification via SBA or an approved third-party certifier with a program exam every three years; SDVOSB certification transitioned from the VA to SBA on January 1, 2023, and self-certification ended by December 22, 2024.

Numbers & thresholds

Exceptions & edge cases

8(a): The program is a one-time lifetime use; individuals may participate only once. Financial thresholds apply to the qualifying owner. The firm must generally have been in business for at least two years to demonstrate potential for success. Sole-source limits are higher for entity-owned firms (e.g., tribally owned). Annual certification of continued eligibility is required.

HUBZone: HUBZone designations update every five years; the most recent update was in 2023, with changes scheduled for 2026 and 2028. Firms must notify SBA of mergers or acquisitions. The 35% employee residency requirement must be met continuously.

SDVOSB: Self-certification is no longer permitted after December 22, 2024; formal SBA VetCert certification is mandatory for goaling and subcontracting purposes. VOSB (non-service-disabled) set-asides are limited to the VA under the Vets First policy. For permanently and totally disabled veterans, a spouse or caregiver may manage daily operations.

WOSB: Set-asides are available only in NAICS codes where SBA has determined women-owned businesses are underrepresented; some contracts are restricted to EDWOSBs only. Certification can be obtained through SBA free online or through one of four approved third-party certifiers, but firms must still upload documentation to SBA Certifications before competing. Annual attestation is currently in abeyance.
