The U.S. Small Business Administration has proposed a sweeping rule that would reshape how the federal government defines a “small business” across 338 industry groups.
The changes would dramatically increase the number of companies qualifying as small businesses for government contracts and SBA purposes, affecting average annual revenue and employee-count thresholds.
The proposed overhaul touches nearly every sector of the economy, from agriculture and manufacturing to construction, IT, and professional services.
Federal law requires the SBA to revisit its size standards every five years, but the agency is describing this round as a historic departure from past practice.
Rather than maintaining hundreds of narrow classifications tied to individual six-digit North American Industry Classification System codes, the proposal shifts toward a broader, market-based approach built around four-digit industry groupings.
That structural change alone would cut the number of distinct size standard categories by an estimated 65 percent, from nearly 1,000 down to 338.
If the proposed rule is finalized as written, SBA projects that 37,002 firms holding $71 billion in existing contracts will become newly eligible as small businesses.
Contractors that have operated comfortably in restricted competitions will face a materially larger field of qualified competitors, many of them sophisticated firms with established past performance that simply outgrew prior thresholds.
For government agencies, the expanded pool should ease the perennial challenge of meeting the statutory 23 percent small business contracting goal, though it raises questions about how contracting officers will adjust acquisition strategies.
Once approved, the new formulas will convert many size standards from receipt-based to employee-based standards, a shift the SBA says will benefit smaller federal contractors significantly.
“The act of winning a contract will not by itself force a firm to transition into a large business,” SBA wrote in the proposal, highlighting one of its central policy goals.
The rule could also spare successful small businesses from what has often been called the “valley of death,” the difficult period after graduation from small business eligibility but before a firm is large enough to compete openly.
On the other hand, some existing small business contractors will be displeased by having to compete with businesses carrying much higher revenues and better access to capital.
The proposed rule is also expected to trigger an explosion of corporate transactions within the government contracts space, as businesses reassess their competitive positioning under the new thresholds.
The proposed rule is just that — proposed, and no new size standards are in effect or would go into effect unless and until SBA issues a final rule.
SBA is accepting public comments on the proposed rule for 30 days, with submissions accepted through the Federal eRulemaking Portal at www.regulations.gov under RIN 3245-AI67 or Docket No. SBA-2026-0199.
Public comments can be submitted until 21 September 2026, giving stakeholders an opportunity to weigh in on one of the most significant small business policy shifts in recent memory.
