The Department of Treasury is not one procurement shop. It is a collection of bureaus, each with its own contracting office, its own priorities, and its own relationships with small business liaisons. The IRS is the largest by far. The Bureau of Engraving and Printing, the U.S. Mint, the Financial Crimes Enforcement Network, the Office of the Comptroller of the Currency, and the Bureau of the Fiscal Service all buy separately. If you treat Treasury as a monolith, you will miss the entry points.
What Treasury actually buys and how much
Treasury-wide contract obligations run approximately $6–7 billion per year based on USASpending.gov data for recent fiscal years. The IRS accounts for roughly $3–3.5 billion of that, making it one of the ten largest civilian agency buyers in the federal government.
The top spend categories across Treasury bureaus:
- Information technology — systems modernization, cybersecurity, data infrastructure, help desk. The IRS Modernization program is the single largest driver. The agency has been under a congressional mandate to modernize COBOL-era systems for years, and the Inflation Reduction Act added $80 billion over ten years (though subsequent budget negotiations have trimmed that figure).
- Professional and management support services — program management, financial analysis, training, communications.
- Facilities and operations — the IRS has over 400 offices nationally; the Mint and BEP operate manufacturing facilities.
- Printing and engraving — BEP is essentially a manufacturing operation; the Mint procures metals, equipment, and specialized services.
- Financial services and audit support — OCC and FinCEN buy compliance-adjacent services.
IT and professional services dominate for small business purposes. If your NAICS codes fall in the 5400s (professional services) or 5100s (IT), Treasury is a realistic target.
Which set-aside programs Treasury uses
Treasury uses all the major small business set-aside programs. The mix skews toward 8(a) and HUBZone in IT, which reflects both SBA goals and the geographic concentration of IRS facilities in areas that qualify as HUBZones.
8(a) Business Development Program: The IRS routes a meaningful share of IT task orders through 8(a) vehicles. If you hold an 8(a) certification and are on a contract vehicle like SEWP V, CIO-SP3, or Alliant 2 SB, you are positioned for sole-source awards under $4.5 million and competitive 8(a) set-asides above that threshold. IRS contracting officers use SEWP V heavily for commodity IT and support services.
HUBZone: Treasury and the IRS use HUBZone set-asides, particularly for services work tied to IRS campuses in cities like Austin, Kansas City, Ogden, and Atlanta. Several of these areas have HUBZone-designated tracts. Check the SBA HUBZone map against IRS facility ZIP codes before assuming you do or do not qualify.
WOSB and EDWOSB: Treasury uses Women-Owned Small Business set-asides in NAICS codes where women-owned firms are underrepresented per SBA's official list. Many IT support and professional services NAICS codes qualify. EDWOSB (economically disadvantaged) set-asides are usable in a broader list of codes.
SDVOSB: Treasury uses Service-Disabled Veteran-Owned Small Business set-asides, though at lower volume than VA. The IRS does obligate SDVOSB dollars annually; they show up most often in facilities, training, and some IT support categories.
SDB price evaluation adjustment: Treasury contracting officers can apply a 10% price evaluation adjustment for Small Disadvantaged Businesses in unrestricted competitions. This applies to 8(a) firms and other SDB-certified companies even when the contract is not set aside.
A practical note: Treasury is not the easiest agency to break into via open-market competition. The set-aside pathways are more accessible for first-time vendors. Prioritize getting on an IDIQ vehicle before trying to win a standalone Treasury contract.
How to find Treasury opportunities
beta.SAM.gov: Filter by agency = "Department of the Treasury" and set-aside type (8(a), HUBZone, WOSB, etc.). The IRS posts Requests for Information and Sources Sought notices before formal solicitations; responding to these is one of the better ways to get your name in front of a contracting officer before the RFP drops.
FPDS-NG: Go to fpds.gov and search by agency code. Treasury's FPDS agency code is 2000; IRS is 2050. Pull contract action data to see which primes are winning, which NAICS codes are active, and which contracting officers are writing awards in your category. This is background research, not opportunity hunting, but it tells you who already has the relationships.
IRS Procurement Forecast: The IRS publishes an annual procurement forecast at irs.gov. It lists anticipated contracts by category, estimated value, set-aside type, and projected award date. The quality and completeness vary by year, but it is worth downloading and sorting by NAICS code.
Treasury OSDBU: The Office of Small and Disadvantaged Business Utilization at Treasury (treasury.gov/osdbu) publishes vendor events, procurement forecasts, and contact information for small business specialists at each bureau. The OSDBU does not make award decisions, but it can make introductions and flag upcoming requirements before they are formally posted.
IRS Small Business Specialist: Every IRS contracting office has a dedicated Small Business Specialist. These are the people who review upcoming acquisitions and recommend set-aside designations. Getting a meeting with one is worth more than most marketing activities.
Registration and portal requirements beyond SAM.gov
SAM.gov registration is the baseline. Beyond that:
DUNS/UEI: SAM.gov now uses the Unique Entity Identifier (UEI) system, which replaced DUNS numbers in 2022. Make sure your SAM registration is current and your entity is "active" — not just registered. Registrations expire annually.
Treasury Vendor Portal: Treasury does not operate a separate vendor portal the way DHS or DOD does. Contracting happens through the standard federal acquisition system, primarily through SAM.gov and agency-specific systems.
IRS Information Assurance and IT security requirements: If you are pursuing IT work at the IRS, be prepared for IRS Publication 4812 (Contractor Information Technology Security) requirements. You will need to address these in technical proposals. Some IRS IT vehicles require a formal security review before you can even bid.
ORCA/Representations and Certifications: These live inside your SAM.gov registration. Keep them current. Treasury contracting officers check them.
Cage Code: Required for any federal contract. It is generated automatically when your SAM registration is complete.
Subcontracting through prime contractors
Most Treasury and IRS IT work flows through large IDIQ vehicles and established prime contractors. The subcontracting path is often faster than prime contracting for a first-time Treasury vendor.
Key prime contractors active on IRS and Treasury work based on FPDS data:
- Booz Allen Hamilton: Major presence on IRS IT modernization and financial management work.
- Deloitte: Active on IRS and Treasury financial systems and compliance programs.
- SAIC: IT infrastructure and systems integration work at IRS.
- Leidos: Enterprise IT services across Treasury bureaus.
- Accenture Federal Services: Transformation and systems work at IRS.
- Unison: A mid-tier firm with notable IRS presence, including work on the Integrated Modernization Business Plan.
Each of these firms has a small business subcontracting plan as a federal requirement. They are legally obligated to use small and diverse subcontractors to meet SBA goals. Contact their subcontracting or supplier diversity offices directly. Bring specific capabilities, not general availability. If you do IRS-relevant work (tax processing, financial data, legacy system modernization, cybersecurity), say so explicitly.
Treasury prime contractors must submit Individual Subcontracting Reports (ISRs) via the Electronic Subcontracting Reporting System (eSRS). Their contracting officers track whether they hit small business subcontracting goals. That creates real demand for qualified diverse subcontractors.
Practical first steps
Step 1: Confirm your NAICS codes match where Treasury spends. Pull your top five NAICS codes and check them against FPDS data for Treasury (agency code 2000) and IRS (2050). If there is no award history in your codes at these agencies, either your codes are wrong or the market is thin. Fix one of those two things before spending time on outreach.
Step 2: Get on a contract vehicle. SEWP V, CIO-SP3, and Alliant 2 Small Business are the primary vehicles for IRS IT work. If you are not on one of these, getting there is worth the investment. SEWP V has an open on-ramp process. Check the SEWP website for current status.
Step 3: Respond to IRS Sources Sought notices. When the IRS posts a Sources Sought or RFI on SAM.gov, respond. These responses go into a market research file that contracting officers use when deciding whether to set a contract aside. A written response does not commit you to anything, but it gets your capabilities on record.
Step 4: Contact the IRS OSDBU and your bureau's Small Business Specialist. Request a capabilities briefing. Come with a one-page capability statement (not a pitch deck) that lists your NAICS codes, past performance, contract vehicles, and certifications. Keep it under two pages.
Step 5: Work the subcontracting angle in parallel. Identify two or three primes from the FPDS list above. Email their small business liaison with a short note: your company, your certifications, your specific relevant experience, and a request for a brief call. Follow up once. Do not spam. Primes remember vendors who are direct and prepared.
The IRS is not a fast buyer. Award cycles run long. Budget fights and continuing resolutions delay everything. Plan for a 12-to-24-month horizon from first contact to first award. That is not pessimism. It is the actual timeline for most first-time Treasury vendors.
