For government contractors, SBA size standards are more than an administrative definition. They determine who gets to compete as a small business, how long growing firms can stay in that market, and which companies agencies can count toward small business contracting goals.
On August 20, 2026, the Small Business Administration proposed a significant rewrite of both its size standards and the methodology used to calculate them. The proposal would establish new standards for 338 industry groups and industries and could bring more than 114,000 additional businesses into the small business category. Comments are due September 21, 2026.
For GovCons, this is worth watching closely. If finalized, the changes could give growing contractors more room before they graduate out of small business status. They could also bring much larger competitors into set-aside markets that some small businesses have historically viewed as their lane.
What SBA Is Actually Proposing
Today, SBA size standards vary by industry and generally use either average annual revenue-based receipts or number of employees to determine whether a company qualifies as small. Those standards affect eligibility for federal set-asides and small business contracting programs, along with other SBA programs.
The new proposal changes more than the dollar or employee threshold for a few NAICS codes. SBA is proposing to change how it thinks about business size in the first place.
Five proposed changes stand out and what it means:
Fewer individual standards: SBA would move from nearly 1,000 industry-level standards to 338 standards calculated primarily at the 4- and 5-digit NAICS level.
More employee-based standards: Where SBA has discretion, the methodology would generally default to employee count instead of receipts.
New market-based methodology: SBA would focus on national industry size, geographic markets, and net imports rather than the seven factors used in its 2024 methodology.
No explicit maximum: The new calculation retains a minimum size standard but removes the explicit maximum used under the prior methodology.
Productivity adjustment: Receipts-based standards would account for productivity growth in addition to inflation.
SBA says the shift to broader NAICS groupings is intended to reduce confusion and simplify the current structure. It also proposes removing existing size-standard exceptions.
That simplification may sound technical, but the downstream effects could be significant.
The Biggest Change May Be How SBA Thinks About Growth
The current system has long created what many GovCons know as the small business “graduation” problem.
A company grows. Revenue increases. It wins larger work, adds employees, and builds the past performance needed to compete for more complex contracts. Then it crosses its NAICS size threshold and suddenly has to compete as an other-than-small business, often against companies with substantially greater scale, resources, and past performance.
SBA explicitly addresses that dynamic in the proposal. The agency argues that size standards that do not keep pace with business growth can create a disincentive for companies approaching the threshold. Its proposed methodology is designed to give growing businesses more room before they lose small business status.
The addition of productivity growth is especially important for receipts-based standards. SBA notes that it has historically adjusted those standards for inflation, but not for the increase in economic output businesses can generate from the same resources over time. Under SBA’s analysis, the original $1 million receipts standard from 1954 would equal about $9.7 million today based on inflation alone, but approximately $30.6 million when productivity growth is also considered.
That is a substantial difference in how SBA defines what growth actually means.
More Companies Could Qualify as Small
The scale of the proposed change is easier to see in SBA’s own estimates.
SBA projects the number of businesses qualifying as small would increase from approximately 6.34 million to 6.46 million, an increase of close to 2 percent. Overall, the agency estimates approximately 114,541 businesses could become newly eligible for small business status.
More notable for the GovCon market, approximately 37,002 of those companies already held federal contracts in FY2025. Those firms accounted for roughly 105,655 contracts totaling more than $71 billion.
Some of the largest concentrations are directly relevant to the professional services and technology contracting market:
Engineering Services: 5,314 firms
Other Computer Related Services: 2,247 firms
Custom Computer Programming Services: 2,171 firms
Administrative Management and General Management Consulting Services: 1,818 firms
Computer Systems Design Services: 1,663 firms
Other Professional, Scientific, and Technical Services: 1,427 firms
If the proposal is finalized as written, companies in these categories should expect the competitive map to move.
For Growing Small Businesses, This Could Extend the Runway
There is an obvious upside for contractors approaching their current size thresholds.
Instead of managing growth around an artificial ceiling, some firms could gain more time to build the capabilities required to compete effectively in the unrestricted market. That could mean another contract cycle to deepen agency relationships, expand past performance, invest in infrastructure, strengthen financial capacity, or build a more diversified pipeline.
That matters because graduating from small business status is not simply a SAM.gov update. It changes the competitive environment.
A firm that has built its pipeline around small business set-asides may need to compete against much larger organizations overnight. The proposed standards could push that transition point further out and give contractors more time to prepare for it. SBA itself describes the proposal as a way to move the “benefit cliff” and allow firms to continue growing without immediately sacrificing small business eligibility.
For those firms, the message should not be “we can stay small longer.” It should be “we have more runway to prepare for what comes next.”
For Existing Small Businesses, Expect More Competition
The other side of the proposal is just as important.
If more companies qualify as small, existing small businesses will face more eligible competitors for set-aside opportunities. SBA acknowledges that increased competition is likely to have the greatest effect on businesses that are closest in size and capability to the firms newly entering the small business category.
That could change pursuit strategy in several ways:
More eligible firms → More competition for set-asides → Greater pressure on differentiation, relationships, pricing, and past performance
Simply qualifying as small will matter less when the field gets deeper.
For contractors accustomed to seeing the same handful of competitors in a particular NAICS category, this is a reason to revisit competitive intelligence now. Which firms currently classified as other-than-small would become eligible under the proposed threshold? Where do they already have agency relationships or incumbent positions? Which set-aside markets could suddenly become more crowded?
Those are capture questions, not just compliance questions.
Agencies Could See the Market Differently Too
The proposal would also change the pool of suppliers available to federal buyers.
Federal agencies have a government-wide goal of awarding at least 23 percent of prime contracting dollars to small businesses. If the proposal takes effect, agencies could count awards to newly qualified firms toward those goals, and those companies could compete for procurements restricted to small businesses. That may make it easier for contracting officers to find enough capable small businesses to support a set-aside decision in some markets. SBA argues that a broader pool should increase competition and give agencies more options for price, quality, and delivery.
For contractors, that means historical assumptions about whether a procurement is likely to stay small-business set-aside may need another look.
What GovCon Leaders Should Do Now
This is still a proposed rule, not a final change. Contractors should not change their size representations based on these proposed standards today. SBA is accepting comments through September 21, 2026.
But waiting for a final rule to understand the impact would be a mistake.
GovCon leaders should be modeling three things now:
Your own status. Compare your primary NAICS codes and growth forecast against the proposed standards.
Your competitive set. Identify current other-than-small competitors that could become small under the proposal.
Your pipeline. Revisit upcoming set-asides, recompetes, teaming strategies, and agency markets where a larger eligible pool could change the pursuit.
The bigger point is that size standards shape strategy long before a contracting officer checks the box in SAM.
If SBA finalizes this approach, many growing contractors could get valuable additional runway. At the same time, the definition of “small business competition” could become meaningfully more competitive.
The contractors best positioned for that change will not simply track whether their NAICS threshold moved. They will understand how the new standard changes who they compete against, which opportunities they pursue, and how aggressively they need to prepare for the next stage of growth.
