SBA Extends Public Comment Period on Historic Size Standards Overhaul to November 20
Federal contractors navigating small business set-asides have been granted additional breathing room. Following widespread industry feedback and tens of thousands of formal submissions, the U.S. Small Business Administration (SBA) extended the public comment window for its sweeping size standards overhaul by 60 days, moving the deadline from late September to November 20, 2026.
The proposed rules (Docket Nos. SBA-2026-0199 and SBA-2026-0265), initially published on August 20, 2026, represent the most comprehensive restructuring of small business eligibility criteria in decades. Under the current framework, size standards are fragmented across roughly 1,000 six-digit NAICS codes, often penalizing fast-growing mid-tier contractors who abruptly "size out" into full-and-open competition against multi-billion-dollar defense primes.
The SBA's proposed overhaul replaces this system by consolidating standards into 338 broader industry groups at the four- and five-digit NAICS level. It eliminates all previous maximum caps, shifts numerous service sectors from annual revenue thresholds to employee headcount caps, and introduces a simplified formula based on national market size and productivity.
According to SBA estimates, this restructuring will make approximately 114,541 commercial firms newly eligible as small businesses—including roughly 37,000 active contractors holding over $71 billion in federal awards. While this grants expanding mid-tier contractors a vital runway to stay competitive in set-aside pools, it also introduces better-resourced competitors into competitions historically dominated by smaller firms.
With comments now accepted through November 20, contractors have an extended window to model the competitive impact on their primary NAICS codes and submit data-backed feedback before final regulations take effect.
