What Qualifies as a Small Business
The federal size standard that decides SBA eligibility, in plain numbers by industry.
Under federal law, a business is considered "small" if it falls below the size limit set by the U.S. Small Business Administration (SBA) for its specific industry.
There isn't one universal cutoff. Depending on the industry, the SBA sets the limit by average annual revenue or number of employees.
Each limit is tied to a North American Industry Classification System (NAICS) code. That means a general contractor and a real estate brokerage can both qualify as small businesses while being held to different size standards.
On August 20, 2026, the SBA proposed a broad rewrite of nearly 1,000 of these limits. The public comment period runs through September 21, 2026, so some standards that apply today could change before the end of the year.
These standards determine eligibility for SBA loans, federal contracting set-asides, and some grant programs. They do not determine how a business is organized, licensed, or taxed.
How the SBA Size Standard Works
The size standard is a two-part test, and a business only needs to fail one part to lose small-business status.
The first part measures average annual receipts: total income plus cost of goods sold, averaged across the latest five complete fiscal years.
The second part measures average employee count across the latest 24 pay periods, counting every worker on payroll at the company and its affiliates, full time or part time.
Most industries use only one of the two tests. Very few get measured by both. The NAICS code assigned to the business decides which test applies.

The 500-Employee Rule Is Only a Default
Most people who have heard of an SBA size limit know one version: 500 employees or fewer. That figure is the manufacturing default, and it is only a default.
For most non-manufacturing industries, the SBA instead uses a receipts-based test. The general threshold across the current table runs under $7.5 million in average annual receipts.
Real estate shows how far that shortcut can miss. An office of real estate agents and brokers, NAICS 531210, currently qualifies as small at up to $15 million in average annual receipts, more than double the $7.5 million default.
A company that leases out residential or commercial buildings, NAICS 531110 and 531120, gets an even higher ceiling: $34 million in average annual receipts under the table effective since March 17, 2023.
Those exact figures are the ones most likely to move under SBA's pending August 2026 revision, so confirm them on SBA's size-standards page before relying on them for a loan or bid.
Small Business Means Different Things to Different Federal Rules
SBA's own size standard is not the only federal definition tied to business size, and mixing the two up is a common mistake.
Other federal laws set their own employee-count lines for their own purposes, and none of them use SBA's per-industry test.
The Affordable Care Act's employer mandate applies at 50 full-time-equivalent employees. Title VII of the Civil Rights Act applies at 15 employees. The Family and Medical Leave Act applies at 50 employees within a 75-mile radius.
None of those thresholds care what industry a business is in, and none of them decide SBA loan or federal-contracting eligibility. A company can clear the SBA size standard for its industry and still fall under one of these separate employee-count rules.
Forming an LLC Is Not Required to Qualify as Small
No federal law requires a business to form an LLC before it can operate or qualify as small. A sole proprietorship, the default structure for a one-owner business with no separate filing, can be a small business under SBA's test.
An LLC, S corporation, or corporation instead changes liability protection and how the business is taxed. Most owners pick an entity structure for asset protection or investor requirements, a choice that is separate from SBA size eligibility.
A business license is a different requirement, set by the state, county, or city rather than the SBA. Almost every business needs at least a general local license or permit to legally operate, and specific trades such as contracting, food service, cosmetology, and real estate brokerage need added state licensing on top of that.
About Half of New Businesses Reach Their Fifth Year
Just over half of new U.S. business establishments survive five years, according to Bureau of Labor Statistics data that tracks establishments from their opening quarter forward.
Survival rates vary sharply by industry. Food service and retail trade consistently post the lowest five-year survival rates in BLS data, while the average surviving establishment roughly doubles its headcount within ten years of opening.
None of that data answers whether one specific business idea is worth pursuing. It only shows the base rate a new owner is working against before industry, funding, and local demand come into play.
Basic Accounting Requirements for a Small Business
A small business has to track two things from day one: every dollar moving in and out, and enough documentation to support a tax return.
Most owners choose between cash-basis and accrual-basis accounting. Cash basis records income and expenses when money moves, which is simpler for a business with no inventory. Accrual basis records income and expenses when they are earned or billed, closer to what a lender or investor expects to see.
The IRS requires separate recordkeeping for business and personal expenses regardless of entity type. Most small businesses move to accounting software or a bookkeeper rather than tracking receipts by hand once revenue passes a few hundred thousand dollars a year.
How to Confirm the Current Standard for a Specific Industry
SBA publishes a free lookup tool that returns the exact receipts or employee limit for a specific NAICS code. The result always matches whichever version of the table is currently in force.
Because the size standards are under proposed revision as of September 2026, a figure pulled from an old PDF or a blog post can already be stale.
Confirm the exact current figure for a specific NAICS code on SBA's size-standards page before submitting a loan application, a bid, or a small-business certification.
Frequently Asked Questions
- It depends on the industry and whether that industry uses an employee-based test at all. Many services industries use a receipts test instead and carry no employee cap. Where an employee cap does apply, SBA's current table sets it anywhere from under 100 employees to as high as 1,500 employees depending on the specific NAICS code, so 500 employees is a common default rather than a universal ceiling.
- No. A sole proprietorship qualifies as a small business under SBA's test just as an LLC or corporation does. Forming an LLC changes liability protection and taxation. It does not change small-business eligibility, and most owners choose it for asset protection rather than any size requirement.
- Almost always, yes, but the license comes from the state, county, or city rather than the SBA. A general local business license or permit is close to universal, and specific trades such as contracting, food service, and real estate brokerage require additional state licenses on top of it.
- A NAICS industry code assigned to the business, paired with either a maximum in average annual receipts or a maximum employee count. SBA sets one or the other for each code. The number itself changes by industry.
- No. That figure is SBA's default for most manufacturing NAICS codes only. Most non-manufacturing industries use a receipts-based test instead, commonly a limit around $7.5 million in average annual receipts, with individual industries set well above or below that figure.
- An office of real estate agents and brokers, NAICS 531210, currently qualifies as small at up to $15 million in average annual receipts. A business that leases residential or commercial buildings, NAICS 531110 or 531120, qualifies at up to $34 million. Both figures come from the table effective since March 17, 2023, and both are candidates for change under SBA's pending 2026 revision.
- Track every dollar in and out from day one, and keep business expenses separate from personal ones regardless of entity type, which the IRS requires. Most owners pick cash-basis accounting for its simplicity early on, then move to accrual-basis accounting, software, or a bookkeeper as revenue and transaction volume grow.
- The size-standard question and the worth-it question are separate. On survival alone, just over half of new U.S. business establishments make it to their fifth year according to Bureau of Labor Statistics data, with wide variation by industry. That base rate says nothing about a specific idea, funding level, or local market, which are the factors that decide the answer for one business.
