Federal Set-Asides Explained: WOSB, 8(a), HUBZone, SDVOSB

Federal set-asides explained: WOSB, 8(a), HUBZone, SDVOSB

A large share of federal contracts is reserved — 'set aside' — for specific categories of small businesses. If you're certified, these are some of the least competitive, highest-value opportunities available to you.

The main set-aside programs

  • Small Business Set-Aside — reserved for any qualifying small business.
  • WOSB — Women-Owned Small Business.
  • 8(a) — for socially and economically disadvantaged small businesses.
  • HUBZone — businesses in Historically Underutilized Business Zones.
  • SDVOSB — Service-Disabled Veteran-Owned Small Business.

Every opportunity on SAM.gov is tagged with its set-aside type. The trick is catching the ones you qualify for among the thousands of monthly notices — and responding before the deadline.
