A small business is an independently owned and operated company that operates on a smaller scale than large corporations, typically based on its number of employees, annual revenue, or both. However, there is no single employee or revenue limit that defines every small business.
In the United States, the Small Business Administration (SBA) uses industry-specific size standards. For research purposes, the SBA Office of Advocacy generally considers an independent business with fewer than 500 employees to be a small business, but eligibility for federal programs can depend on a company’s industry, annual receipts, employee count, and relationships with affiliated businesses.
That means a one-person consulting company, a family-owned restaurant, a 40-person construction company, and even a manufacturer employing hundreds of people may all qualify as small businesses under different circumstances.
What Qualifies as a Small Business?
A business is generally considered small when it operates independently and remains below the applicable size threshold for its industry.
For U.S. federal contracting and certain SBA programs, the definition is more specific. The SBA establishes size standards representing the maximum size a company can reach while still qualifying as a small business. These standards usually use either:
- The business’s average number of employees
- Its average annual receipts
The applicable limit varies by industry and is associated with the company’s North American Industry Classification System (NAICS) code.
The SBA also considers factors beyond the headline employee or revenue number. For relevant federal programs, businesses generally must be for-profit, independently owned and operated, and not nationally dominant in their field. A company’s affiliates may also need to be included when calculating its size.
This distinction matters because there is a difference between calling a company “small” in everyday conversation and determining whether it legally qualifies as small for a particular government program.
Small Business Size Is Not the Same in Every Industry
One of the most common misconceptions is that every company with fewer than 500 employees automatically qualifies as a small business.
The fewer-than-500-employees definition is useful as a broad research benchmark, but official SBA eligibility can depend on the company’s specific industry. Some industries use employee limits, while others rely on annual receipts.
Consider these hypothetical businesses:
| Business | Employees | Annual Revenue | Could It Be a Small Business? |
|---|---|---|---|
| Freelance graphic design studio | 1 | $90,000 | Very likely |
| Local bakery | 12 | $850,000 | Very likely |
| Plumbing company | 35 | $6 million | Potentially |
| Regional manufacturer | 300 | $75 million | Potentially, depending on its industry |
| National corporation | 8,000 | $4 billion | Generally not |
The examples show why headcount alone can be misleading. A company that appears relatively large compared with a neighborhood shop may still fall within an SBA size standard for its industry.
Conversely, meeting a simple employee threshold does not automatically establish eligibility for every program.
Examples of Small Businesses
Small businesses operate across nearly every part of the economy. They are not limited to storefront retailers or family-owned restaurants.
Common examples include:
- Independent restaurants and coffee shops
- Landscaping companies
- Plumbing and electrical contractors
- Accounting firms
- Digital marketing agencies
- Online stores
- Freelance consulting businesses
- Software development companies
- Auto repair shops
- Construction contractors
- Beauty salons and barbershops
- Cleaning companies
- Small manufacturers
- Photography businesses
- Local retailers
- Property management firms
A small business can operate from a commercial property, a home office, a warehouse, a shared workspace, or entirely online.
It also does not need employees to be considered a business. Many entrepreneurs operate nonemployer businesses, meaning they have no paid employees other than the owner or owners.
In fact, nonemployer operations make up a substantial portion of American business activity. The Census Bureau reported more than 30.4 million nonemployer establishments in the United States for 2023, compared with millions of firms employing workers.
Small Business vs. Startup: What Is the Difference?
A startup can be a small business, but the terms describe different characteristics.
“Small business” primarily refers to business size. “Startup” usually describes a company at an early stage that is attempting to develop and validate a business model, often with an emphasis on rapid growth.
| Small Business | Startup |
|---|---|
| Defined primarily by size | Defined primarily by development stage and business model |
| May pursue steady, sustainable growth | Often aims for rapid growth |
| May serve a local or specialized market | May target a large or scalable market |
| Can remain small indefinitely | Usually intends to grow substantially |
| May rely on owner financing, loans, or operating cash flow | May pursue angel or venture capital funding |
For example, a neighborhood bakery operating profitably for 20 years may remain a small business throughout its existence.
A software company with eight employees may also currently be a small business, but if its founders are developing a product designed for rapid national or international expansion, it could simultaneously be described as a startup.
The categories are therefore not mutually exclusive.
Small Business vs. Self-Employment
Self-employment and small-business ownership also overlap, but they are not identical concepts.
A self-employed person earns income by working for themselves rather than exclusively as an employee of another organization. A freelance writer, independent consultant, photographer, or tradesperson might therefore be self-employed.
Some self-employed people operate businesses without employees. Others eventually hire workers and build larger companies.
A small business can likewise employ dozens or even hundreds of people, depending on the industry and applicable definition.
For example:
Scenario 1: A freelance web designer works alone and earns $80,000 per year. The designer is self-employed and operates a small business.
Scenario 2: A web development agency employs 25 designers and developers. Its founder may be a business owner, but the company itself is an employer business rather than a one-person self-employment operation.
The difference becomes important when dealing with taxes, payroll, employment obligations, financing, insurance, or government programs.
Why the Definition of a Small Business Matters
Business size can affect access to financing, government contracts, regulatory programs, certifications, data reporting, and other opportunities.
One particularly important area is federal contracting.
The federal government reserves certain contracting opportunities for qualifying small businesses. To compete for contracts set aside for small businesses, a company must satisfy the applicable SBA size standard.
Classification can also matter when evaluating:
- SBA programs
- Government procurement opportunities
- Certain grants or assistance programs
- Industry statistics
- Business certifications
- Lending opportunities
- Economic development programs
- State or local incentives
The definition used by one organization may not necessarily match another organization’s definition. A bank, state government, research institution, or private company can use different criteria for its own program.
For that reason, business owners should check the rules of the specific program rather than relying solely on a general definition of “small business.”
How the SBA Determines Whether a Business Is Small
For federal purposes, determining business size usually begins with the company’s industry.
1. Identify the NAICS Code
The North American Industry Classification System categorizes businesses according to the economic activities they perform.
A business generally has a primary NAICS code reflecting its main activity, although companies offering several products or services can have multiple codes.
2. Find the Applicable Size Standard
The SBA publishes size standards associated with individual NAICS industries.
Depending on the industry, the threshold may be expressed as:
- Number of employees, or
- Average annual receipts
The standard represents the maximum size a business may generally reach while continuing to qualify as small for purposes covered by that standard.
3. Calculate the Company’s Size
A company then determines the relevant employee count or average annual receipts according to SBA rules.
This calculation can be more involved than simply looking at this year’s revenue or today’s payroll.
4. Consider Affiliates
Affiliation is an especially important issue that businesses sometimes overlook.
For SBA size determinations, employees or receipts belonging to affiliates may need to be included in the calculation. Affiliation can arise when another person or organization has the power to control a business, even if that control is not actively exercised.
As a result, creating several legally separate companies does not necessarily mean each company will always be evaluated independently for SBA size purposes.
How Big Can a Small Business Be?
Potentially much bigger than many people expect.
Everyday language often associates a small business with a company employing perhaps five, ten, or twenty people. Federal definitions can be considerably broader.
The Census Bureau reported that there were approximately 5.58 million U.S. firms with at least one employee but fewer than 500 employees in 2023. It also reported more than 30.4 million nonemployer establishments that year.
These figures illustrate the enormous range covered by the small-business economy.
A self-employed professional generating $60,000 in annual sales and an industrial company employing several hundred workers obviously operate on very different scales. Nevertheless, both may fit a relevant definition of a small business.
This is why “small” should not automatically be interpreted as “tiny.”
What Is a Microbusiness?
A microbusiness generally refers to a particularly small business, often one with only a handful of employees.
The exact definition depends on the organization or program using the term. Unlike an everyday general definition of small business, there is no single universal employee threshold that applies to every use of “microbusiness.”
Examples could include:
- A one-person bookkeeping service
- A two-person photography studio
- A family-run online store
- A small cleaning business with four employees
- A consultant operating through a single-member company
A microbusiness can therefore be considered a subset of the broader small-business category in many contexts.
Business owners should still check the exact eligibility definition when a loan, grant, government program, or certification specifically uses the term “microbusiness.”
Can an Online Business Be a Small Business?
Yes. A business does not need a physical retail location to qualify as a small business.
An e-commerce seller, software company, digital marketing agency, online consultant, subscription business, or virtual service provider may all operate as small businesses.
What matters is the applicable definition and the company’s characteristics, not whether customers visit a storefront.
A one-person online store earning $150,000 per year can be a small business just as a neighborhood retailer can. Likewise, an internet company employing hundreds of people could potentially remain within an industry-specific size standard until it exceeds the applicable threshold.
The business model and sales channel do not, by themselves, determine whether a company is small.
Is a Franchise a Small Business?
A franchise location may be considered a small business in some circumstances, but franchise status alone does not determine the answer.
Franchises create an important distinction between brand size and business ownership. A locally owned franchise location can operate under the name of a large national brand while still being owned by an independent business operator.
For programs governed by SBA requirements, however, business owners must consider the relevant size and affiliation rules rather than assuming that independent ownership automatically guarantees small-business status.
This is a good example of why the legal or program-specific definition can differ from the way consumers normally think about small businesses.
Does Business Structure Determine Whether a Company Is Small?
No. A company’s legal structure does not, by itself, determine whether it is a small business.
Small businesses can operate under several structures, including:
- Sole proprietorships
- Partnerships
- Limited liability companies (LLCs)
- Corporations
For relevant SBA federal contracting rules, a qualifying small business can use different for-profit legal structures provided it satisfies the applicable requirements.
A corporation is therefore not automatically a large business, just as forming an LLC does not automatically make a company a small business.
Business structure primarily determines matters such as ownership, liability, governance, and taxation. Business-size classification addresses a different question.
How to Check Whether Your Business Qualifies as Small
If you only need an informal description, employee count, revenue, independence, and overall scale may be enough to decide whether calling your company a small business makes sense.
For a government contract or another program with formal eligibility rules, use a more precise process:
- Identify your company’s primary business activity.
- Find the corresponding NAICS code.
- Check the current SBA size standard for that industry.
- Determine whether the standard uses employees or annual receipts.
- Calculate your size using the applicable SBA methodology.
- Include affiliates when required.
- Confirm any additional requirements imposed by the specific program.
Do not rely on an old size threshold copied from a blog or previous application. SBA size standards can change. The SBA maintains current and historical size-standard information and provides industry-specific data used for federal contracting determinations.
This is particularly relevant in 2026 because the SBA has proposed changes to its size-standard framework. A proposal is not automatically the same as an effective final rule, so businesses making eligibility decisions should use the standards actually in force at the time they apply.
Frequently Asked Questions
How many employees can a small business have?
There is no universal maximum. The SBA Office of Advocacy commonly uses fewer than 500 employees for research purposes, but official eligibility limits vary by industry. Some SBA size standards also use annual receipts rather than employee numbers.
Can one person be considered a small business?
Yes. Millions of businesses operate without paid employees. Sole proprietors, freelancers, consultants, and other independent operators can run legitimate small businesses.
Is an LLC automatically a small business?
No. LLC describes a legal business structure, not the size of the company. An LLC might be a one-person operation or a much larger organization.
Can a business make millions of dollars and still be considered small?
Potentially. Small-business classification depends on the applicable industry standard. Some businesses can generate substantial annual revenue and still qualify as small under the relevant rules.
Are startups considered small businesses?
Many early-stage startups are small businesses because they initially have relatively few workers or modest revenue. However, “startup” describes the company’s stage and growth model, while “small business” describes its size under a particular definition.
Are small-business rules the same in every country?
No. Definitions vary between countries, governments, financial institutions, statistical agencies, and individual programs. U.S. SBA standards should not be assumed to apply in another jurisdiction.
Conclusion
A small business is generally an independently operated company that remains below certain employee or revenue thresholds, but there is no single size limit that applies to every business.
In everyday use, the term can describe anything from a self-employed freelancer to a company employing hundreds of workers. For U.S. government programs and federal contracting, however, the SBA uses industry-specific standards that typically consider employees or average annual receipts, along with factors such as affiliation.
If you need to determine whether a particular company officially qualifies as a small business, start with its NAICS industry and check the current SBA size standard rather than relying on the commonly cited 500-employee benchmark alone.
