SBA Size Standards Overhaul: What Federal Contractors Should Do Before September 21
The Small Business Administration (SBA) has proposed a major overhaul of size standards, a rewrite of the standards used to determine whether a company qualifies as "small" for federal contracting and other programs. The proposal is not yet effective, but it is important because it would change the industry classifications, measurement methods, and thresholds that define access to small-business opportunities. Comments on the proposed rule are due September 21, 2026.
Executive Answer: Model the Rule, But Do Not Bid as Though It Is Final
Contractors should treat the proposal as a planning scenario, not as a current eligibility determination. Build a side-by-side file showing your present NAICS codes and size standards, the proposed standard, employee or receipts data, affiliates, pending proposals, and relevant set-aside or certification programs. Then use that model to decide whether to comment, adjust pipeline assumptions, or prepare for new competition. The proposed rule has no stated effective date; it remains a proposal until SBA completes its rulemaking.
SBA filed two related Federal Register documents on August 20. The proposed rule would establish 338 size standards—276 at the four-digit NAICS industry-group level and 62 at the five-digit industry level, in place of the current structure of 978 six-digit standards and 18 exceptions. SBA also published a revised methodology that explains how those standards were developed.
What the SBA Size Standards Overhaul Would Change
The proposal would simplify the classification framework by grouping many related industries at the four-digit level and removing all federal-contracting size-standard exceptions. SBA says this would reduce uncertainty about which standard applies and make it easier for businesses and contracting officers to identify the relevant classification. The proposal still uses five-digit standards where SBA concludes that a broader industry group would be too general.
The proposal also changes the preferred measure of business size. Of the 338 proposed standards, 208 would be employee-based, 129 would be receipts-based, and one would be asset-based. SBA's revised methodology generally defaults to employee-based standards unless a service-based industry is required by law to use receipts. SBA says this could reduce volatility caused by revenue swings, inflation, and productivity growth, and could reduce the risk that winning a contract alone pushes a firm over a receipts threshold.
The methodology itself is also different. SBA proposes to calculate "average market size" using three components: national industry size, the number of geographic markets in which competition occurs, and an adjustment for net imports. It would then translate that measure into a size standard using a single formula, with no explicit maximum size standard and a retained minimum. SBA also proposes to adjust receipts-based standards for productivity growth as well as inflation.
SBA estimates that the proposal would increase the number of eligible small businesses from 6,344,967 to 6,459,508, a net increase of 114,541, or about 1.8 percent. The companion methodology document separately estimates that approximately 114,000 businesses would be reclassified as small and that 172 businesses currently classified as small could become large under the proposed methodology. These estimates are not a promise to any individual company; the result depends on the final rule, the applicable NAICS classification, and the firm's facts.
Why This Matters to Small and Mid-Sized Federal Contractors
A size standard is more than a label in a registration profile. SBA states that federal agencies generally use its standards to determine small-business status, and that a newly classified small business could become eligible to pursue opportunities restricted to small businesses, including certain SDVOSB, WOSB, HUBZone, and 8(a) opportunities—subject to each program's separate requirements. The proposal also says contracts awarded to newly small businesses could count toward agency small-business goals.
That creates two different strategic effects. First, some growing firms may regain access to set-asides or avoid the "benefit cliff" that can discourage investment near a size threshold. Second, the eligible pool could expand, increasing competition for restricted requirements. A contractor that is newly eligible should not assume that eligibility equals past performance, certification, contract-vehicle access, or a winning position. A contractor that remains small should not assume its competitive field will look the same.
The proposal is especially relevant to services and technology firms. Among firms with FY2025 contracts that SBA estimates could become newly eligible, the largest listed groups include Engineering Services (NAICS 541330), Other Computer Related Services (541519), Custom Computer Programming Services (541511), Administrative and General Management Consulting Services (541611), and Computer Systems Design Services (541512). SBA estimates that nearly 37,002 firms with FY2025 contracts could become newly eligible, representing approximately 105,655 contracts and more than $71 billion in FY2025 contract value.
Those figures should be used as a market signal, not as a forecast of awards. More firms in the eligible pool may improve agency access to capable sources, but it can also make a set-aside harder to win. The practical question for a contractor is not simply "Will I be small?" It is "How will the proposed classification and threshold change my addressable pipeline, competitors, partner strategy, and compliance workflow?"
Five Actions Contractors Can Take Now
1. Build a Current-Versus-Proposed Eligibility Map
List every NAICS code used in SAM, current solicitations, active contracts, and internal pipeline. For each, record the present size standard, your relevant employee or receipts measure, and the proposed four- or five-digit classification and threshold. Flag any area where the proposal would move you from receipts to employees or combine your current industry with another group.
Do not rely on a single top-line revenue number. Include subsidiaries, affiliates, ownership changes, and other facts that may affect a size analysis. This is a business-planning checklist, not a legal opinion; a contractor should obtain professional advice for a specific representation, protest, transaction, or certification question.
2. Separate Small-Business Status from Program Eligibility
The proposal says that firms newly classified as small could compete for small-business opportunities, but it also emphasizes that socio-economic programs have additional requirements. For example, size status alone does not establish SDVOSB, WOSB, HUBZone, or 8(a) eligibility. Keep those certification and location requirements in a separate workstream instead of treating the new size standard as a universal pass.
3. Re-Score the Pipeline
For each pending opportunity, identify the likely NAICS code, contract type, set-aside posture, incumbent, and competitors that could be newly eligible. Run at least three scenarios: current rules, proposed rules as written, and a conservative scenario in which the final rule changes thresholds or classifications. This can reveal where a newly eligible competitor changes bid/no-bid logic, where a current set-aside strategy becomes less attractive, and where a teaming arrangement is more valuable than a prime bid.
4. Decide Whether to Submit Targeted Comments
SBA is requesting comments on the level of NAICS aggregation, the choice between employee and receipts measures, the geographic-market approach, the data sources, the anchor points, and the treatment of federal-contracting exceptions. Comments are due September 21, 2026 under RIN 3245-AI67 and Docket SBA-2026-0199 for the proposed standards. The companion methodology notice uses Docket SBA-2026-0265.
The most useful comment is usually specific. Explain the industry classification you use, the proposed classification, the operational facts that make the grouping inaccurate or useful, and the effect on real federal opportunities. If a proposed threshold would change an active pipeline, quantify the type and timing of that effect without disclosing protected procurement information.
5. Prepare for Data and Registration Hygiene
SBA says businesses seeking federal contracting participation must register in SAM, update profiles annually, and self-certify small-business status at least annually when participating in federal procurement and certain other programs. The proposed rule says it would not add new reporting or recordkeeping requirements, but a changed standard makes accurate NAICS, employee, receipts, ownership, and affiliation records more important—not less.
CIG Advisory Perspective: Make the Policy Measurable
The strongest contractor response is not to wait for a final rule or to market a speculative eligibility claim. It is to create a decision file that management can update as the rule moves through comments and finalization. That file should show: current status; proposed status; the data and assumptions behind each result; affected opportunities; likely competitor changes; certification dependencies; and a decision owner for each next step.
This is where acquisition intelligence adds value. The proposal changes the apparent size of the market, but the business impact depends on how agencies use set-asides, which NAICS codes appear in upcoming requirements, what contract vehicles are available, and whether a contractor can prove relevant past performance and pricing. A firm may be technically eligible yet poorly positioned; another may remain small but need to change its teaming and opportunity-qualification strategy because the competitive pool has widened.
CIG's practical question for partners is therefore: Which parts of your pipeline are sensitive to a size-standard change, and what evidence would make the decision actionable? The answer should be visible in a repeatable model—not buried in a general compliance memo.
Bottom Line
SBA's proposal could expand small-business contracting access while changing the competitive landscape. It is not current law, and contractors should not represent themselves based on a proposed threshold. But the September 21 comment deadline makes this the right time to map NAICS classifications, model current and proposed eligibility, review certification dependencies, and quantify pipeline effects. Contractors that do that work now will be better prepared whether the final rule closely follows the proposal or changes materially during rulemaking.
FAQ Section
1. Is SBA's new size-standard overhaul already effective?
No. The August 20 documents are a proposed rule and a notice requesting comments on a revised methodology. The proposed rule does not state an effective date. Contractors should continue using the applicable current rules unless and until SBA finalizes a change.
2. When are comments due?
SBA must receive comments on the proposed size standards and the revised methodology by September 21, 2026. The proposed standards use RIN 3245-AI67 and Docket SBA-2026-0199; the methodology uses Docket SBA-2026-0265.
3. How many size standards would the proposal create?
SBA proposes 338 standards: 276 at the four-digit NAICS industry-group level and 62 at the five-digit industry level. The proposal would remove all federal-contracting size-standard exceptions.
4. Would more firms qualify as small businesses?
SBA estimates a net increase of 114,541 eligible small businesses, from 6,344,967 to 6,459,508. The estimate is subject to the final rule and each firm's applicable classification and facts.
5. Does becoming small automatically qualify a firm for 8(a), HUBZone, WOSB, or SDVOSB opportunities?
No. SBA explains that each program has additional eligibility requirements. A proposed change to size status should be analyzed separately from certification, ownership, location, economic-disadvantage, and other program requirements.
6. What should a contractor do first?
Build a current-versus-proposed map of NAICS codes, thresholds, employee or receipts data, affiliates, certifications, and pipeline opportunities. Use the result to decide whether to submit a fact-specific comment and how to update bid, teaming, and compliance plans.
