"Small business" is a phrase everyone uses and few can size. The U.S. Small Business Administration's Office of Advocacy is the authoritative source — it compiles Census Bureau data under a single definition — so every figure on this page comes from it, stamped with the report it appears in.
The small-business figures
The figures below come from the Office of Advocacy, which for research purposes generally defines a small business as an independent business with fewer than 500 employees. That definition is why the count reaches tens of millions: it includes the vast number of sole proprietors and non-employer firms alongside small employer companies. Counts are from the 2025 Small Business Profile and the 2026 Frequently Asked Questions publication.

How these figures were compiled
What is counted: only figures the U.S. Small Business Administration’s Office of Advocacy publishes, in its own terms. The SBA’s definition of a small business — generally fewer than 500 employees — is broader than most people assume, and every figure here inherits that definition rather than a narrower one we might prefer.
What is excluded: any figure we cannot tie to a named SBA report with a date. We do not derive per-state counts, project forward, or blend SBA data with other sources to produce a number nobody published.
How it is kept current: the verification date changes only when each figure has actually been re-checked against the source. September 2026: advocacy.sba.gov returns 403 to automated retrieval, so this page cannot be re-verified by the same scripted check as the others — it was re-checked by hand in a browser instead, against the Office of Advocacy’s 3 February 2026 release and its 30 June 2025 Small Business Profiles release. Every figure still matched. The previous stamp was deliberately held at July 2026 while that manual check was outstanding, because a stamp that was not earned is worse than no stamp at all; the check has now been done, so the date moves.
What the manual check resolved: three rows — net new jobs, new establishments opened, and the share of net new jobs — previously read “latest data year” without naming it. The Office of Advocacy’s 2025 Profiles release states the period explicitly: March 2023 to March 2024. Those rows now name it. This matters because the Office of Advocacy’s 2026 FAQ counts business openings on a different basis and for a different period, and an unstated period is exactly the gap where two incompatible figures get mistaken for one another.

Taken together, these figures make one point clearly: small businesses are not a corner of the economy but most of it by count, and a large share of it by employment and output. They are 99.9 percent of U.S. businesses, employ nearly half the private-sector workforce, and generate more than four in every ten dollars of GDP. That is the context in which bookkeeping matters — the books being kept across 36 million small firms are, collectively, the ledger of most of American enterprise.
The shares, drawn to scale

What the numbers mean for accounting
The scale is the argument. When 36.2 million businesses each need books that reconcile and reports that can be trusted, the quality of small-business accounting is not a specialist concern — it is an economy-wide one. Most of those firms run on a handful of tools, QuickBooks prominent among them, and most are staffed too leanly to have a full accounting department checking the work. That gap between how much bookkeeping the economy needs and how little review most files get is exactly where a cleanup earns its keep.
For your own business, the national numbers are backdrop; the questions that matter are local to your file. A free review answers them directly — does every account reconcile, does the balance sheet balance, does the profit-and-loss reflect how the business actually ran — with no figure estimated or invented along the way. That is the same standard we hold these statistics to.
