Set-Aside Contracts Explained: Small Business, 8(a), HUBZone, WOSB and SDVOSB

Set-aside contracts are federal contracts reserved for small businesses. In a small business set-aside, only firms that are small under the contract's size standard can bid, so you compete against companies your size instead of large ones. Other set-asides are limited to firms certified in one SBA program: 8(a), HUBZone, women-owned (WOSB) or service-disabled veteran-owned (SDVOSB).

What is a small business set-aside?

A set-aside limits who can compete for a contract. The agency decides before it posts the solicitation, and the set-aside type appears on the notice and on the solicitation's cover page. If you don't qualify for it, you can't win that contract, however good your price is.

Set-asides are common. On September 25, 2026, FedReady's search of SAM.gov data showed 3,446 open notices reserved for small businesses or Indian-owned firms. That's about 31% of the 11,129 open opportunities that day.

Indian economic enterprise set-asides are a separate program that this guide doesn't cover.

Total vs. partial small business set-asides

• Total set-aside: the whole contract is reserved for small businesses. This is the kind you'll see most.
• Partial set-aside: only part of a larger buy is reserved for small businesses, and the rest is open to any company. Agencies use one when a total set-aside isn't appropriate and the work can be split into distinct portions. Partial set-asides aren't used for construction or for buys under simplified acquisition procedures.

Set-aside vs. sole-source awards

In a set-aside, eligible firms compete against each other. In a sole-source award, the agency gives the contract to one certified firm without a competition. Each SBA program allows sole-source awards up to a ceiling, including options:

Note that the SDVOSB ceiling is $5 million, not $5.5 million. Each program adds its own conditions before a sole-source award is allowed, so treat these as upper limits, not promises. For 8(a), the figure is the point above which 8(a) firms generally must compete. SBA can accept larger sole-source awards in limited cases, such as for firms owned by tribes or Alaska Native Corporations.

The rule of two

The rule of two decides most small business set-asides. A contracting officer must reserve a buy for small businesses when they reasonably expect offers from at least two responsible small businesses at fair market prices. Two versions of the rule are in use as of September 2026:

• The codified FAR (19.502-2): buys above $15,000 up to $350,000 must be set aside unless the contracting officer doesn't expect two competitive small business offers. Buys above $350,000 are set aside when that expectation exists.
• The FAR overhaul text agencies have adopted (19.104-1): one test for every contract above $15,000. The contracting officer must set it aside when they expect offers from two or more responsible small businesses that are competitive on price, quality and delivery.

The overhaul's small business part hasn't been formally proposed as a rule yet, so its wording could still change. Either way, contracting officers learn whether two capable small businesses exist through market research, including sources sought notices. Your answer to one can help tip a buy into a set-aside. See how to find government contracts for where to find them.

Small business set-asides: no certification needed

To bid on a total small business set-aside, you need three things:

1. Be small for that contract. Size standards are set for each NAICS code, as average annual receipts or average number of employees. The contracting officer generally assigns one NAICS code to each solicitation. Your size is measured against that code's standard as of the date of your first offer that includes price. Check yours with SBA's size standards tool, and see who can get government contracts for more.
2. Say so in SAM.gov. You represent your size in your SAM.gov registration. There's no separate application.
3. Do enough of the work yourself, when the rule applies. Limits on subcontracting apply to small business set-asides above $350,000, and to 8(a), HUBZone, WOSB and SDVOSB contracts of any size. On a services contract, you generally can't pay more than 50% of what the government pays you to subcontractors that aren't "similarly situated," meaning they aren't small businesses with the same status as you. The limit is also 50% for supplies (not counting materials), 85% for general construction and 75% for special trade construction.

Certified firms can bid on these too, as long as they're small under that NAICS code.

8(a) certification: the 8(a) program in 2026

The 8(a) Business Development program helps small businesses owned by socially and economically disadvantaged people. It lasts nine years at most: four developmental years, then five transitional years.

8(a) certification requirements, in brief:

• At least 51% owned and controlled by U.S. citizens who are socially and economically disadvantaged.
• Personal net worth of $850,000 or less, adjusted gross income of $400,000 or less, and total assets of $6.5 million or less.
• Potential for success. As of September 2026, SBA generally wants two years of business tax returns showing revenue and two full years of contract work in your primary NAICS code. It can waive this only in narrow cases, and a declined applicant must wait 90 days to reapply.
• Small, and never in the 8(a) program before.

What changed in 2025 and 2026:

• June 27, 2025: SBA ordered a full audit of the program.
• December 5, 2025: SBA ordered all participants, about 4,300 firms, to provide financial records.
• January 2026: SBA suspended 1,091 firms following that document request.
• March 4, 2026: SBA moved to terminate more than 620 firms that refused to turn over financial data.
• September 10, 2026: a final rule took effect that removes the presumption of social disadvantage for individually owned firms.

Under the new rule, individual owners can't rely on membership in a group to show social disadvantage. An applicant must submit evidence that a government or private entity's policy or practice favored other groups or disadvantaged the applicant's group, and certify that it caused them material harm. The rule applies to new and pending applications from individually owned firms. It doesn't apply to firms owned by tribes, Alaska Native Corporations, Native Hawaiian Organizations or Community Development Corporations. Current participants that SBA already found socially disadvantaged don't have to prove it again.

Starting September 10, 2026, SBA is returning pending applications from individually owned firms. After SBA's notice, you have 45 calendar days to update and resubmit, or the application is closed and you must start over. SBA also says it will review every applicant's potential for success on the merits and give priority review to firms in 10 defense-critical industries.

Benefits: 8(a) set-asides, and sole-source awards up to $5.5 million ($8.5 million for manufacturing). In fiscal year 2025 (FY2025), 8(a) firms won about $24.3 billion in federal prime contracts, 3.7% on SBA's scorecard.

HUBZone certification and the HUBZone map

The HUBZone program helps businesses in historically underutilized business zones. The HUBZone certification requirements are:

• Small, and at least 51% owned and controlled by U.S. citizens (or by certain entities, such as a Community Development Corporation, agricultural cooperative, Alaska Native Corporation, Native Hawaiian Organization or Indian tribe).
• Your principal office is in a HUBZone.
• At least 35% of your employees live in a HUBZone.

Use SBA's HUBZone map to check whether your office and your employees' home addresses are in qualified areas. The map changes over time: SBA says it's due for an update at some point in 2026 as some redesignated areas expire. Check your addresses again before you apply and before you recertify.

Benefits: HUBZone set-asides, sole-source awards up to $5.5 million ($8.5 million for manufacturing), and a 10% price evaluation preference when you compete in full and open competitions. Recertification: every three years. In FY2025, agencies missed the 3% HUBZone goal, reaching 2.66%.

WOSB certification requirements (WOSB and EDWOSB)

The Women-Owned Small Business (WOSB) program reserves contracts for women-owned firms in eligible industries. The WOSB certification requirements are:

• At least 51% owned and controlled by women who are U.S. citizens.
• Women manage the business day to day.
• Small under the size standard for your NAICS code.

An economically disadvantaged women-owned small business (EDWOSB) meets those rules and more. Each woman owner has a net worth under $850,000, adjusted gross income of $400,000 or less (averaged over three years), and assets of $6.5 million or less.

How to qualify: you need SBA certification. Self-certification ended in October 2020. If you already hold an SBA-approved third-party certification, you can upload it to MySBA Certifications. SBA says it will decide within 90 calendar days of a complete application whenever practicable.

Benefits: WOSB and EDWOSB set-asides, but only in the eligible industries on SBA's list of qualifying NAICS codes, plus sole-source awards up to $5.5 million ($8.5 million for manufacturing). In FY2025, agencies missed the 5% WOSB goal, reaching 4.52%.

SDVOSB set-aside contracts for veterans (and VOSB)

SBA certifies veteran-owned businesses through its VetCert program. It took over from the Department of Veterans Affairs (VA) on January 1, 2023. There are two statuses:

• Service-disabled veteran-owned small business (SDVOSB): at least 51% owned and controlled by one or more veterans rated as service-disabled by the VA. SDVOSBs can win set-asides and sole-source awards at any federal agency. Since January 1, 2024, those awards require SBA certification.
• Veteran-owned small business (VOSB): at least 51% owned and controlled by one or more veterans. VOSB set-asides are only at the VA, under its Vets First program.

If you're looking for set-aside contracts for veterans across the whole government, SDVOSB is the program that opens them. SDVOSB sole-source awards go up to $5 million ($8.5 million for manufacturing). You recertify every three years. The SDVOSB goal rose from 3% to 5% in the National Defense Authorization Act for fiscal year 2024 (FY2024), and agencies reached 5.01% ($32.5 billion) in FY2025.

How to get certified, and how the programs compare

Where to apply, and what it costs

Apply for 8(a), HUBZone, WOSB, EDWOSB, VOSB and SDVOSB certification at MySBA Certifications. SBA calls it "home to SBA's free online certification process." You don't need a consultant to apply. APEX Accelerators and Small Business Development Centers can help for free.

Can you hold more than one certification?

Yes, if you meet each program's rules. SBA says that, provided they're eligible, WOSB-certified firms can still compete under other programs, including 8(a) and HUBZone. For example, a woman-owned firm with its principal office in a HUBZone could hold both certifications and bid on WOSB, HUBZone and small business set-asides. Every certified firm must be small, so it can also bid on small business set-asides in NAICS codes where it's small.

One related option: in SBA's Mentor-Protégé Program, a small business teams with a more experienced mentor for up to six years. The two can form a joint venture that bids as a small business.

Why agencies look for certified firms: the goals

SBA grades agencies each year on goals for the share of prime contract dollars that go to small businesses. These were the government-wide goals as of September 2026:

In FY2025, small businesses won about $179 billion in federal prime contracts, down from $183.5 billion in FY2024 but still well above the 23% goal. The goals give agencies a reason to look for qualified small businesses. SDB status uses the same disadvantage criteria as 8(a), and it isn't settled how the 2026 rule affects it, so check SBA's current guidance if you represent as an SDB.
