The Quiet Majority of U.S. Businesses
Small business has always been the backbone of the American economy. But behind the storefronts and corporations we recognize, there’s a massive segment of entrepreneurs working quietly on their own. These are sole proprietors — individuals who operate businesses without forming a corporation or partnership. They make up the largest share of business owners in the country by far, and their growth over the last 25 years reveals a major shift in how Americans earn a living.
While corporations often dominate headlines and political discussions, the reality is that the modern U.S. economy runs on self-employed people. From freelance designers and real estate agents to independent truckers and gig-app drivers, sole proprietorships now outnumber all corporations combined.
What Is a Sole Proprietorship?
A sole proprietorship is an unincorporated business owned and run by one person. It’s the simplest and most common structure for small businesses in the United States. The owner and the business are legally the same entity — meaning the owner keeps all profits but is also personally responsible for all debts and liabilities.
Unlike corporations or limited liability companies (LLCs), sole proprietorships don’t require registration with the state beyond local permits or business licenses. The owner simply reports business income and expenses on Schedule C of their personal Form 1040 tax return. This simplicity makes it the easiest entry point into entrepreneurship.
The downside is that sole proprietors have unlimited personal liability. If the business is sued or can’t pay its debts, the owner’s personal assets could be at risk. Despite that, millions of Americans continue to choose this structure for its flexibility and low cost.
How Many Sole Proprietorships Exist?
According to the most recent data from the Internal Revenue Service (IRS), there were about 31 million active sole proprietorships in the United States as of tax year 2022. That’s up from roughly 17 million in 1997 — an increase of more than 80 percent in a single generation.
IRS “Schedule C” filings show steady growth over time:
-
1997 — 16.9 million
-
2003 — 19.7 million
-
2019 — 27.9 million
-
2020 — 28.3 million
-
2021 — 29.3 million
-
2022 — 30.98 million
Each of those figures represents a person reporting self-employment income, usually without any employees. The U.S. Small Business Administration estimates that about 86 percent of all non-employer firms — those without payroll — are sole proprietorships. That means roughly 25 million people are working entirely for themselves, often from home or through digital platforms.
Comparing Sole Proprietors, S-Corps, and C-Corps
To see how dominant sole proprietors have become, it helps to compare them with incorporated businesses. Based on IRS data:
-
S Corporations (Form 1120-S) grew from about 2.5 million in 1997 to 5.3 million in 2022.
-
C Corporations and other corporate forms (Form 1120) remained flat around 1.5 to 2 million during the same period.
-
Sole Proprietorships surged from 17 million to nearly 31 million.
The result is clear: self-employed individuals now make up the overwhelming majority of all U.S. business filings. S-corps overtook traditional C-corps in the early 2000s as pass-through taxation became more popular, but both corporate types combined still account for only about one-fifth the number of sole proprietors.
This trend shows a fundamental reshaping of the business landscape. Americans increasingly prefer independence, flexibility, and low overhead over traditional corporate structures.
Why the Surge in Sole Proprietorships?
Several long-term trends explain the steady rise in self-employment:
-
Technology and the Gig Economy
The rise of apps and online platforms has made it easy to start earning as an independent contractor. Rideshare drivers, delivery workers, and freelance professionals can all operate as sole proprietors with just a smartphone and a 1099 form. -
Remote Work and Side Hustles
The pandemic accelerated the shift toward home-based work. Millions began side businesses — from consulting and tutoring to selling crafts online — to supplement their income or replace full-time jobs. -
Ease of Formation
Forming an LLC or corporation requires state filings, separate tax returns, and annual fees. A sole proprietorship can begin operating immediately, with no separate paperwork beyond a Schedule C at tax time. -
Digital Marketplaces
Platforms like Etsy, Amazon, and Shopify have turned hobbyists into business owners overnight. These online ecosystems allow individuals to operate globally without ever forming a corporation. -
Demographic and Lifestyle Changes
Many retirees or mid-career professionals choose self-employment for flexibility. Others launch micro-businesses to gain autonomy after leaving traditional jobs.
Combined, these forces have made the sole proprietor model the natural fit for a digital, decentralized economy.
Growth Over the Last 25 Years
To visualize the shift, imagine a simple chart showing three lines from 1997 to 2022:
-
Sole proprietorships rise sharply from 17 million to 31 million.
-
S-corps climb moderately from 2.5 million to 5.3 million.
-
C-corps and other corporations remain almost flat around 1.5 million.
This tells a powerful story about American entrepreneurship. In 1997, there were roughly eight sole proprietors for every C-corp. Today, there are more than twenty. The number of people working for themselves has grown even as large corporations consolidate or automate.
It’s not just tax filings that have grown. The types of businesses have diversified: independent tech developers, social-media creators, real-estate flippers, e-commerce resellers, and niche consultants all fall under the same legal structure. In the 1990s, sole proprietorships were dominated by small retail and service shops; today, they span nearly every professional category imaginable.
The Pros and Cons
Advantages:
-
Extremely easy and inexpensive to start
-
Complete control and decision-making power
-
Simple tax reporting (income passes directly to the owner)
-
No need for separate corporate filings
Disadvantages:
-
Unlimited personal liability for debts or lawsuits
-
Limited ability to raise capital or take on investors
-
May appear less formal to clients or lenders
-
Can face higher self-employment taxes
Despite the risks, the simplicity often wins out — especially for freelancers and solo operators who value independence more than liability protection.
The Bigger Picture
The growing share of sole proprietorships reflects a larger social and economic transformation. America’s workforce is shifting from long-term employment toward self-directed work. Many young people see entrepreneurship not as a risky leap but as a normal career path. Digital platforms, online education, and new payment tools have made it easier than ever to run a one-person enterprise.
At the same time, the traditional corporation isn’t disappearing — it’s just becoming more specialized. S-corps remain attractive for small firms with a few employees, and large public companies still dominate stock markets. But in raw numbers, the future of small business clearly belongs to independent owners.
The Bottom Line
If you want to understand the modern U.S. economy, look beyond Wall Street and Fortune 500 companies. The real growth engine is the tens of millions of Americans who work for themselves. Over the past 25 years, the number of sole proprietorships has nearly doubled, while corporate filings have barely changed.
Sole proprietors now represent more than three-quarters of all active business tax returns in the country. Their rise marks a cultural shift toward autonomy, flexibility, and personal entrepreneurship — the defining traits of the twenty-first-century economy.
