Doing Business with the IRS


A2. Before doing business with the IRS, the company must verify it is a small business.

  • Small businesses may partner with a prime contractor for some federal contracts which require a subcontracting plan of outsourced work. A Contracting Officer may include specific subcontracting goals for the prime contractor to try to meet.
  • In its proposal to a large business, a small business must self-certify as small for the NAICS code on the solicitation. If a small business fails to do this, a subcontract will not count toward small business subcontracting goals.
  • Any large business can publish outreach events, notices of sources sought, and solicitations for subcontracting work to the subcontracting database, in an effort to locate small business subcontractors.
  • The IRS Small Business Program Office conducts and/or participates in outreach events outreach events annually, as well as the Department of the Treasury's Office of Small & Disadvantaged Business Utilization (OSDBU) to assist transparency and to promote opportunities with small businesses.
    • Matchmaking events
    • Industry days
    • Reverse industry days
  • Vendor can also use the Dynamic Small Business Search (DSBS) to find small businesses.

A4. A company can do business with the IRS through:

  • Partnering
  • Contractor team arrangement (CTA) partnership - not a new company
  • Joint venture (need SBA approval) - new company formed
  • Mentor-protégé (agreement under SBA, prime contractors assist small businesses) 
  • In support of the governmentwide category management program and ensuring achievement of category management goals, the Department of the Treasury, including the IRS, utilizes governmentwide acquisition vehicles categorized as Best-in-class (BIC).
  • Governmentwide Acquisition Contracts (GWACs) include the following vehicles:
    • OASIS SB
    • Alliant Small Business and Alliant II Small Business
    • VETS2
    • 8(a) STARS II/III (SBA 8(a) vendors)

A7. The BIC acquisition designation identifies government-wide contracts that satisfy key criteria defined by the Office of Management and Budget (OMB). BIC solutions are vetted, well-managed, and recommended — and in some cases required for use. Interagency category teams have worked to designate over 30 Best-in-class contracts to reduce the amount of effort individual buyers spend finding and researching acquisition solutions. Widespread adoption of BIC solutions will:

  • Maximize the government's shared purchasing power, allowing agencies to leverage volume discounts;
  • Help agencies operate more efficiently by reducing administrative costs and contract duplication; and
  • Expand sharing of governmentwide buying data, leading to better-informed business decisions.
  • Acquisition Gateway has additional information.

A23. The federal government's goal is to award at least five percent (5%) of all federal contracting dollars to small disadvantaged businesses each year. SDBs that have been accepted into the 8(a) program greatly attribute to these goals since 8(a) firms are classified as SDBs. To qualify for the 8(a) program, follow this eligibility checklist:

  • Have the owner manage day-to-day operations and make long-term decisions.
  • Have all its principals demonstrate good character.
  • Show potential for success and be able to perform successfully on contracts.

A24. The federal government fully defines which companies qualify for the 8(a) program — including what counts as being economically and socially disadvantaged — in Title 13 Part 124 of the Code of Federal Regulations (CFR).  A preliminary assessment of whether a business qualifies or not can be obtained at the SBA Certify website.

  • Vendor must have a profile at before using the certification website. The information needed will vary based on business structure and whether already participating in other SBA programs.
  • After a vendor successfully completes its certification process through, it will update the company business profile at to show contracting officers that the business is in the 8(a) program.
  • The company will receive a letter in the mail informing it of its application approval status. If accepted into the program, the profile in the Dynamic Small Business Search will show approval date and exit date for the program.
  • Certification will last for a maximum of nine years. The company will need to complete annual reviews to maintain good standing in the program.
  • Note: Before participation in the 8(a) business development program, the company must be certified.
