Executive summary

SBA has extended the public comment periods for its proposed Small Business Size Standards and its Revised Size Standards Methodology until November 20, 2026. The extension is a rulemaking and methodology-comment action—not a final change to a contractor’s current size status. SBA’s notice states that the proposed rule addresses size standards for 338 industry groups and industries and that the methodology explains how SBA establishes, reviews, and modifies those standards. Source: SBA, 91 FR 60524–60525, Docket No. SBA-2026-0199; methodology comments, Docket No. SBA-2026-0265.

For contractors, the useful action is not to predict the final rule. It is to identify the NAICS codes that materially affect the company’s active pipeline, contract vehicles, past performance, and teaming strategy—and to keep proposed changes separate from the standards currently applicable to an offer.

What happened—and what did not

SBA published an extension of comment periods on September 24, 2026. The notice says that SBA had published, on August 20, 2026, a notice of proposed rulemaking and a notice of availability for the revised methodology. Effective on filing September 21, 2026, SBA extended both comment periods by 60 days from the original September 21 closing date. Comments must be received by November 20, 2026. Source: 91 FR 60524, “Summary” and “Dates.”

The scope is specific. SBA says the proposed rule presents new size standards for 338 industry groups and industries; the related revised methodology is the agency’s white paper describing how it establishes, reviews, and modifies small-business size standards, including changes from its 2024 methodology. Source: 91 FR 60525, “Supplementary Information.”

The notice does not establish a new size standard, decide a firm’s eligibility, or answer whether SBA will adopt any proposed change. Until a final rule changes the controlling standard, a team should assess an opportunity using the applicable solicitation, its assigned NAICS code, the corresponding current size standard, and the company’s actual facts.

What this means for contractors

Small businesses and certified firms: Treat this as a monitoring and comment window. If a core NAICS appears in the proposal, capture the proposed treatment separately from the current qualification record. Do not call a proposed threshold the standard governing a current bid.

Prime contractors and teaming leads: Ask partners for current, opportunity-specific representations. Keep a separate regulatory-monitoring note for potential future changes; do not convert that note into a present compliance conclusion.

Capture leadership: Use the comment period to inventory exposure. The high-value questions are which NAICS codes matter, which pursuits depend on them, and whether the company has evidence to support a focused comment. The notice identifies the comment dockets, but it does not supply company-specific eligibility outcomes.

BidSignal qualification checklist

Record the solicitation’s NAICS code and current size standard as a verified opportunity fact.
List the company’s strategically material NAICS codes: pipeline, vehicles, awarded work, and likely teaming roles.
Label the SBA proposal and methodology as regulatory monitoring, not current eligibility.
If the proposal affects a material code, capture the exact proposed change and the relevant docket: SBA-2026-0199 for the proposed rule or SBA-2026-0265 for the methodology.
Decide whether to submit a fact-supported comment by November 20, 2026.
