What is SDB Status?

Small Disadvantaged Business (SDB) status is a federal certification for small businesses owned and controlled by individuals who have been subjected to racial or ethnic prejudice or cultural bias because of their identity as members of a group, without regard to their individual qualities.

SDB certification is distinct from the 8(a) Business Development Program, though there is significant overlap. SDB status provides certain benefits without the full requirements and business development components of the 8(a) program.

Presumed Disadvantaged Groups

SBA presumes the following groups are socially disadvantaged. Individual members still must demonstrate economic disadvantage.

  • Black Americans
  • Hispanic Americans
  • Native Americans
  • Asian Pacific Americans
  • Subcontinent Asian Americans
  • Members of other groups (case-by-case)

Eligibility Requirements

To qualify as an SDB, your business must meet small business size standards and ownership/control requirements.

Business Requirements

  • Small by SBA size standards for primary NAICS
  • For-profit business
  • Located in the United States
  • Good character (principals)

Ownership Requirements

  • 51%+ owned by disadvantaged individual(s)
  • U.S. citizens
  • Control management and daily operations
  • Make long-term decisions for the business

Economic Disadvantage Standards

Disadvantaged individuals must also meet economic disadvantage thresholds:

$850,000
Max Personal Net Worth
$400,000
Max Adjusted Gross Income
$6.5M
Max Total Assets

Note: Primary residence is excluded from net worth calculation. These thresholds are subject to change.

  • • Subcontracting opportunities (prime SDB goals)
  • • Enhanced evaluation for some solicitations

  • • Foundation for 8(a) program application
  • • No program term limits (unlike 8(a))
  • • Less intensive requirements than 8(a)

Price Evaluation Adjustment

One of the most significant benefits of SDB status is the price evaluation adjustment in competitive acquisitions.

How Price Adjustment Works

In competitive acquisitions where price is a factor, contracting officers may apply up to a 10% price evaluation adjustment for SDB offerors.

Example:

Non-SDB Proposal: $1,000,000

SDB Proposal: $1,050,000

Adjusted Non-SDB: $1,100,000 (+10%)

SDB wins at actual $1,050,000

Adjustment Discretion

The price evaluation adjustment is not automatic. Contracting officers decide whether to apply it based on the specific procurement. It's typically included in solicitations when appropriate.

SDB vs 8(a) Program

SDB certification and the 8(a) Business Development Program are related but distinct.

FeatureSDB8(a)
Program TermNo limit (recertify every 3 years)9 years maximum
Sole Source ContractsLimited (DoD only)Up to $4.5M / $9M
Set-AsidesDoD onlyAll agencies
Business DevelopmentNoneSBA support, mentoring
Price AdjustmentUp to 10%Up to 10% (same)
RequirementsLess intensiveAnnual reviews, business plan

Success Strategies

Consider 8(a) Program

If you qualify for SDB, you likely qualify for 8(a) which provides more benefits. Consider applying for both or 8(a) directly.

Target DoD

DoD is the primary user of SDB set-asides. Focus your marketing on DoD agencies and prime contractors.

Subcontracting Opportunities

Large businesses need SDB subcontractors to meet their subcontracting plan goals. Market your SDB status to primes.

Update Your Profile

Ensure your SAM.gov and DSBS profiles prominently display your SDB certification for visibility.

Frequently Asked Questions

Can I have both SDB and 8(a) certification?

If you're in the 8(a) program, you automatically have SDB status for the duration of your 8(a) term. You don't need separate SDB certification while in 8(a).

What if I don't belong to a presumed group?

You can still apply for SDB status by providing a narrative and evidence demonstrating social disadvantage based on your individual circumstances. SBA evaluates these on a case-by-case basis.

How long does SDB certification last?

SDB certification is valid for 3 years. You must recertify before expiration to maintain continuous status. Annual updates may be required.

Is SDB certification free?

Yes, SDB certification through SBA is free. Be wary of third parties charging for certification assistance—you can apply directly at certify.sba.gov.

What happens if I exceed economic thresholds?

If your personal net worth or income exceeds the thresholds, you would no longer qualify as economically disadvantaged. You must report changes and may lose certification upon recertification review.
