Federal Set-Aside Program

Small Disadvantaged Business (SDB)

A self-represented status for small businesses owned by socially and economically disadvantaged individuals, used mainly to meet federal subcontracting goals.

Who qualifies

  • At least 51% owned and controlled by one or more socially and economically disadvantaged individuals
  • Small under your primary NAICS size standard
  • (8(a)-certified firms automatically qualify as SDB)

How to get certified

SDB is self-represented in SAM.gov (no separate SBA application unless you pursue 8(a)). Primes use it to count toward their small-disadvantaged-business subcontracting goals.

Key benefits

  • Helps prime contractors meet the government-wide 5% SDB subcontracting goal — making you an attractive teaming partner
  • A stepping stone toward the formal 8(a) program

Sole-source authority

SDB itself has no sole-source authority — it’s a representation, not a set-aside. For sole-source disadvantaged awards, pursue 8(a) certification.

Common questions

Is SDB the same as 8(a)?

No. SDB is a self-representation used for subcontracting goals. 8(a) is a formal SBA-certified program with set-aside and sole-source contracting authority. All 8(a) firms are SDBs; not all SDBs are 8(a).
