SBA Is Proposing Major Changes to Small Business Size Standards: What Government Contractors Need to Know
Are you a small business?
It sounds like a simple question.
In government contracting, it isn't.
Whether your company qualifies as "small" depends on the size standard associated with your industry. And on August 20, 2026, the U.S. Small Business Administration (SBA) published a proposed rule that could significantly change how those size standards work.
This isn't just another routine inflation adjustment.
SBA is proposing changes to the structure and methodology used to determine size standards across hundreds of industries — and if finalized, the changes could affect which companies qualify as small businesses for federal contracting and other SBA programs.
Let's break down what is being proposed and, more importantly, what government contractors should be paying attention to.
First: These Changes Are Not Final
This is important.
SBA published a proposed rule, not a final rule. Your current size standard has not changed because of this announcement.
SBA is accepting public comments on the proposal through September 21, 2026.
Until a final rule is issued and becomes effective, contractors should continue using the currently applicable SBA size standards when making size representations.
That said, this proposal is worth watching now because some of the changes are substantial.
SBA Wants to Simplify the Size-Standard System
Currently, SBA's size-standard structure covers 978 six-digit NAICS industries, along with several special exceptions.
Under the proposed rule, SBA would move away from establishing size standards primarily at the six-digit NAICS level.
Instead, size standards would generally be established at the broader four- and five-digit NAICS levels.
The result?
SBA would go from nearly 1,000 individual industry standards to 338 size standards:
276 at the four-digit NAICS level
62 at the five-digit NAICS level
SBA is also proposing to eliminate the existing size-standard exceptions.
The goal is to simplify the system and reduce situations where businesses performing very similar work are subject to different size standards simply because they fall under different six-digit NAICS codes.
For contractors, however, "simpler" doesn't necessarily mean "nothing to worry about."
If your business currently relies on a particular six-digit NAICS code or an industry-specific exception, you'll want to understand where that code lands under the proposed structure.
Another Big Change: Revenue vs. Employees
Today, many businesses determine their size using average annual receipts, while others — particularly manufacturers and certain other industries — use their average number of employees.
SBA is proposing a significant shift in that approach.
Where SBA has discretion, the proposed methodology would generally default to employee-based size standards rather than receipts-based standards.
Under the current structure, 496 industries use annual revenue as the basis for their size standards.
Under the proposal, that number would drop to 129.
Meanwhile, 208 proposed standards would be based on employee count.
Why the change?
Among other reasons, SBA believes employee-based standards may reduce the likelihood that businesses move back and forth between "small" and "other than small" simply because of revenue volatility, inflation or productivity changes.
For growing government contractors, that's a change worth paying attention to.
A contractor that has spent years monitoring its revenue against a particular threshold may eventually find itself measuring size in a completely different way.
SBA Estimates More Than 114,000 Additional Businesses Could Qualify as Small
Here's another significant piece of the proposal.
SBA estimates that approximately 114,541 additional businesses would qualify as small under the proposed standards.
That sounds like great news — and for many companies, it could be.
Businesses that previously exceeded their applicable size standard could potentially regain access to small-business programs and contracting opportunities.
But there's another side to that equation.
More businesses qualifying as small also means more businesses potentially competing for small-business set-asides.
For an existing small government contractor, the question isn't only:
"Will I still qualify as small?"
It's also:
"Who else may now qualify to compete against me?"
That could have real implications for pipeline strategy, competitive positioning and teaming decisions.
But How Big Is Too Big to Be "Small"?
SBA's proposal is intended to solve a real problem: successful small businesses can reach a point where continued growth causes them to lose their small-business status and suddenly puts them in direct competition with the largest companies in the federal marketplace.
Raising size standards gives growing businesses more runway before that happens.
But there's another side to the argument.
If a company with hundreds — or even thousands — of employees qualifies as small, what does that mean for the 20-, 50- or 100-person contractor competing against it for the same small-business set-aside?
Some of the proposed changes put that question into perspective.
Under the proposal, for example:
The size standard for semiconductor manufacturing would increase from 1,250 to 2,800 employees.
Shipbuilding would increase from 1,300 to 2,300 employees.
Oil and gas drilling would increase from 1,000 to 2,650 employees.
A 50-person contractor potentially competing for a small-business opportunity against a company with more than 2,000 employees probably isn't what most people picture when they hear the term "small business."
SBA itself recognizes the potential competitive concern. Expanding the pool of businesses eligible to compete as small could increase competition for existing small businesses, particularly when newly qualifying firms have significantly greater resources, infrastructure and federal contracting experience.
And some of the businesses that could newly qualify as "small" aren't exactly newcomers to the federal marketplace.
Whether companies of that size should still be considered small is a policy question, and reasonable people can disagree.
SBA's position is that the current structure can force successful small businesses out of small-business programs before they're truly prepared to compete against the largest companies in their industries.
The concern from the other side is equally understandable: expanding size standards too far could make it more difficult for genuinely smaller firms to compete within programs specifically designed to create opportunities for small businesses.
For an existing small government contractor, the competitive impact isn't theoretical.
So while the proposal may help solve the problem of successful businesses "graduating" from small-business programs too quickly, it raises an important question:
How large can a business become before calling it "small" begins to undermine the purpose of small-business contracting programs?
Your Company Isn't Simply "Small" or "Not Small"
This is one of the biggest misconceptions I see among companies entering the federal marketplace.
A company doesn't necessarily have one universal small-business status.
Your size status is determined in relation to the NAICS code and corresponding size standard applicable to the procurement.
A company may qualify as small for opportunities under one size standard while being other than small under another.
That's why understanding your NAICS codes — and the size standards associated with the work you're pursuing — matters.
And it's also why a significant restructuring of SBA's size-standard system deserves attention even if your company is comfortably below its current threshold.
What Should Government Contractors Do Right Now?
Don't panic, and don't start changing your SAM.gov representations based on a proposed rule.
But don't ignore it either.
This is a good time to:
Review the NAICS codes you actually pursue. Don't just look at the primary NAICS code listed in your SAM registration. Look at the codes appearing on the opportunities you're bidding and the contracts you're currently performing.
Compare your current standards to the proposed standards. Pay particular attention if your industry would move from a receipts-based standard to an employee-based standard or be consolidated into a broader four- or five-digit category.
Think beyond your own eligibility. Consider whether larger competitors could become eligible to compete as small businesses under the proposed structure. A change that doesn't affect your own size status could still significantly affect your competitive landscape.
Look at your teaming strategy. Changes in size eligibility could affect potential mentors, joint venture partners, subcontractors and competitors.
Watch the rulemaking process. This is a proposal. The final rule may change based on comments SBA receives.
Consider commenting if the proposal significantly affects your business. The public comment process isn't reserved for industry associations and large companies. If a proposed size standard would materially affect your ability to compete, this is an opportunity to explain that impact to SBA.
Don't Wait Until a Solicitation Drops to Check Your Size Status
One of the easiest mistakes for a growing contractor to make is assuming that because it qualified as small last year — or because SAM currently identifies it as small under certain NAICS codes — nothing has changed.
Size standards change.
Companies grow.
Acquisitions use different NAICS codes.
Competitors change.
And under this proposal, the structure used to establish those standards could change substantially.
You don't need to memorize all 338 proposed size standards.
You do need to understand the standards that matter to your business, your pipeline and the contracts you're pursuing.
Because in government contracting, "Are we still small?" shouldn't be a question you first ask when the proposal is due Friday.
The August 20, 2026 SBA rule discussed above is a proposed rule and is subject to change through the federal rulemaking process. Contractors should consult the current SBA size standards and the NAICS code assigned to a specific procurement when determining size eligibility.
