What Is a Small Business?

If your business is one of 31.7 million small businesses in the United States, it’s important to understand the standards and regulations the Small Business Administration (SBA) and other governing bodies impose on your organization. Depending on factors such as number of employees and business structure, your small business may be eligible for certain financial assistance and other advantages and may be subject to different regulations than larger businesses. 

Understanding what qualifies as a small business can help you maintain compliance with industry regulations and access the best opportunities for growing your business.

The SBA defines a small business in terms of the average number of employees over 12 months or average annual revenue over the past 3 years. Depending on the industry, businesses with fewer than 1,500 average employees and maximum gross receipts of $38.5 million per year may qualify as a small business. Any individual or organization that sells goods or services can be a small business, including sole proprietorships, LLCs, partnerships, corporations and other legal structures, as long as they meet employee and revenue standards.

Small business association criteria

The SBA also considers the following factors in determining small business classification:

  • Location: Has a physical location within the United States
  • Economic operation: Operates primarily within the United States or makes a significant contribution to the nation’s economy through taxes or consumption of U.S. materials or labor
  • Financial motivation: Organized for profit
  • Ownership structure: Independently owned and operated
  • Scale: Not nation-wide dominant in its field

NAICS codes

The North American Industry Classification System is a standard system that federal agencies use to classify businesses and organize and analyze data relevant to the U.S. economy. Adopted in 1997, the NAICS system describes your organization’s primary business activities and organizes them within specific numerically-coded groups.

As a small business owner, you’re responsible for assigning your business its NAICS code. You may need to choose more than one code if you operate in multiple niche fields. By classifying your business within a niche, you can compare and analyze metrics across your industry.

For example, some common NAICS codes are:

  • Gas stations: 447110
  • Retail sales: 441110
  • Physicians: 621111
  • Real estate: 531210
  • Software publishers: 511210

Common types of small businesses

Certain industries have few infrastructure or resource requirements to start and, as such, have a relatively large number of small businesses. Many small-scale contractors or organizations may start a small business with few to no employees, basic supplies and low-cost advertising to generate revenue. Some fields that have a large number of small businesses include:

  • Food service
  • Retail
  • Fitness
  • Plumbing, electric and other trades
  • Beauty
  • Web design
  • Childcare
  • Health care
  • Law

Advantages of operating as a small business

The SBA classifies organizations as small businesses to help protect and support them within the broader U.S. economy and against larger businesses. These are some of the advantages of operating as a small business.

Government contracts

The SBA Office of Government Contracting and Business Development collaborates with various federal agencies to provide 23% of government contract dollars to small businesses. This helps ensure that small businesses can maintain a competitive edge against large companies and provides business opportunities for underrepresented groups such as:

  • Women-owned small businesses
  • Service-disabled, veteran-owned small businesses
  • Historically underutilized business zones

In addition to contracts, the SBA offers programs to support disadvantaged small business owners in growing their businesses. Eligible individuals can access support such as workshops, counseling and contract opportunities.


Financing can be a major obstacle for small businesses, but you can access funding through SBA-backed loans. Available through various local lenders in partnership with the SBA, SBA-guaranteed loan options include:

  • 7(a) loans: Loans up to $5 million, typically used for working capital, refinancing debt and purchasing equipment
  • 504 loans: Long-term and fixed-rate financing up to $5 million for major assets that support business growth and job creation
  • Microloans: Loans up to $50,000 that are designated to intermediary lenders to help small businesses start and expand

Compared to other common loan programs, SBA-guaranteed loans typically offer competitive rates and fees. They also come with benefits such as business counseling, low down payments and flexible requirements.

Research grants

The SBA and federal agencies, such as the Department of Energy and the Department of Agriculture, offer a number of research and development programs for small businesses. In addition to contract opportunities, these programs provide businesses with grants to help them expand. Some private grants are also available to small businesses, such as the FedEx Small Business Grant and the Cartier Women’s Initiative.
