How the SBA Size Standard Proposal Could Expand Small Business Eligibility

On August 20, 2026, the U.S. Small Business Administration (SBA) proposed a reset of the SBA size standard for 338 industry groups and industries. The set comment deadline was extended from the original September 21, 2026 to November 20, 2026.  A size standard is the largest size a firm can reach, with its affiliates, and still count as small. Accordingly, federal contracting programs rely on it. SBA estimates the change would add about 110,000 firms to the small-business count.

Two questions matter for your pipeline. Would your firm qualify as small under the proposal? What should your teams do while the rule remains under review? The short answers are that eligibility depends on your assigned NAICS code and the applicable size standard. Also, businesses should continue relying on current SBA size standards unless and until a final rule takes effect.

What Is SBA Proposing in Its Size Standards Rule?

The Small Business Administration (SBA) has proposed streamlining its size standards by replacing its six-digit NAICS (North American Industry Classification System) classifications with 338 consolidated standards established at four- and five-digit levels. This proposal would merge the current table, which includes 978 industry standards and 18 exceptions into a single, simplified schedule. Detailed under RIN 3245-AI67 and published at 91 FR 53741, the proposed rule originally set a comment deadline of September 21, 2026. However, following an extension notice published on September 24, 2026, the public comment period has been extended by 60 days to November 20, 2026.

The Small Business Jobs Act of 2010 (Pub. L. 111-240, September 27, 2010) requires SBA to review all size standards every five years. SBA calls this rule part of its third review. Several proposed changes would affect how businesses are classified and evaluated for small-business eligibility:

• Simplified structure: The current table contains 978 industry standards and 18 exceptions. Under the proposal, SBA would replace them with 338 standards, consisting of 276 four-digit standards and 62 five-digit standards, with no exceptions.
• Greater use of employee-based measures: Today, size standards use a mix of employee-based and receipts-based thresholds. Under the proposal, 208 standards would be employee-based, while 129 would be receipts-based.
• Higher maximum thresholds: The current framework caps receipts-based standards at $47 million and employee-based standards at 1,500 employees. The proposal would eliminate both caps.
• No downward adjustments: Although SBA’s methodology indicated that 45 industries could support lower size standards, the agency proposes not to reduce any existing standards.
• New productivity adjustment: The proposal would incorporate productivity growth into the calculation of receipts-based size standards alongside other economic factors. Under the proposal, SBA would also account for productivity growth when calculating receipts-based thresholds.

How Many More Businesses Would Qualify as Small?

SBA’s August 20, 2026, proposal estimated a net gain of about 114,541 small firms, or 1.8%, across the economy. That total includes 37,002 firms that held federal contracts in fiscal year (FY) 2025, worth more than $71 billion. However, the SBA Office of Advocacy reported on September 17, 2026 that only 4,000 to 6,000 existing contractors would gain small status. It compared that range with about 56,000 firms in the small-business contracting market. SBA also estimated that fewer than 200 firms would lose small status.

Why Does an SBA Size Standard Matter for Federal Contracting?

An SBA size standard decides whether your firm can compete for small-business set-asides, SBA loans, and some regulatory relief. Federal agencies must use SBA’s standards to define a small business unless a statute says otherwise. Therefore, a change in one threshold can move real contract dollars. For example, SBA reports that agencies awarded a record $179 billion in prime contract dollars to small businesses in FY 2024. The statutory goal is at least 23 percent of prime contract value, and awards to newly eligible firms would count toward agency goals.

1. How Does Size Status Affect Set-Asides?

Size status decides whether you can bid on a set-aside, and it shapes how many rivals you face. Under Federal Acquisition Regulation (FAR) 19.502-2, a contracting officer must set aside larger acquisitions when two or more responsible small businesses are expected to offer. Because the proposal enlarges the small-business pool, that test could be easier to meet. As a result, more solicitations may carry a set-aside. However, competition inside each set-aside could also grow. SBA’s own analysis says firms near the threshold would face newly eligible rivals most directly.

2. How Do NAICS Codes and Size Standards Work Together?

Each solicitation carries one NAICS code, and each code carries one size standard. Since the contracting officer picks the code, your firm must meet the SBA NAICS size standard tied to it. Under the proposal, a six-digit code would take the standard of its four-digit or five-digit group. In addition, some measures would change. For example, a receipts-based standard could become employee-based. Therefore, test your firm against both measures.

What Happens If Your Company Becomes Newly Eligible?

You would gain access to small-business set-asides in your NAICS code, but only after SBA publishes a final rule. Until then, existing size standards stay in effect while SBA reviews comments, as the Office of Advocacy confirmed on September 17, 2026. Once a rule takes effect, small and mid-sized contractors would see two effects. First, firms that outgrew a standard may regain set-aside access. Second, firms already small may face larger rivals. SBA also aims to ease the “benefit cliff,” where firms hold back growth to stay small. Thus, a higher SBA size standard lets a firm grow and still bid on set-asides.

1. Why Should You Reassess Your Target Opportunities?

Your best targets may shift because the rival pool, the set-aside mix, and your eligibility can all change. For example, SBA’s August 20, 2026 estimate counted 5,314 FY 2025 contractors in Engineering Services (NAICS 541330) that would become small. It also counted 2,171 in Custom Computer Programming Services (NAICS 541511). However, Advocacy later narrowed the national estimate, so treat those counts with care. Still, review each pursuit by NAICS code, and flag where a rival may gain small status.

2. How Can You Check Your Current Size Status?

Start by finding your NAICS code in SBA’s table of size standards, then measure your firm against it. SBA averages receipts over five complete fiscal years and employees over 24 calendar months. In addition, you must add the receipts and employees of affiliates, meaning firms tied to yours by ownership or control. Next, check your record in SAM.gov, the System for Award Management, where registrants self-certify small status at least once a year. Finally, compare your result under the existing standard and the proposed one.

3. What Does Not Change Just Because You Qualify as Small?

Small status alone does not win awards, and it does not grant certifications. Each preference program keeps its own rules, such as veteran status, economic disadvantage, or location. Examples include the 8(a) Business Development (BD) Program and the Service-Disabled Veteran-Owned Small Business (SDVOSB) Program. The WOSB Program and the HUBZone Program follow the same pattern. Likewise, the NAICS code on the solicitation still controls, and affiliation rules, past performance, and responsibility checks still apply. Therefore, until SBA finalizes the rule, keep your SAM.gov representations on the existing standards.

Practical Guidance

1. Map every target NAICS code to its proposed standard. Use the Federal Register tables to see how each six-digit code folds into a four-digit or five-digit group. This map serves as the basis for every subsequent step.
2. Test your size under both SBA size standard rules. Use the map from step 1 to calculate receipt and employee averages and add affiliates. Then note where your status would change.
3. Rescore your pipeline by NAICS code. Using step 2 results, mark pursuits where you would gain set-aside access or face new rivals. Next, direct capture management effort to the best-scoring bids.
4. Plan teaming for both outcomes. Because rivals and your own status may shift, a partner can protect your position. Therefore, match each partner’s size status to the NAICS code before you commit.
5. Submit data-backed comments by November 20, 2026. Your step 2 results show how the proposal affects your NAICS code, so cite them. SBA added 60 days in a notice published September 24, 2026, and you can file under docket SBA-2026-0199.
6. Hold your SAM.gov status until the rule is final. Meanwhile, keep representations on the existing standards. Once SBA publishes a final rule, repeat steps 1 to 3.

Align Your Bid Strategy Before the Comment Period Closes

SBA accepts comments through November 20, 2026, and the final SBA size standard remains undecided. Therefore, firms that map their NAICS codes and test their size before that date can plan for either outcome. Waiting, by contrast, means reacting after a final rule.
