The commercial insurance a small business actually needs comes down to a short, predictable list. Nearly every business starts with two core coverages, general liability and commercial property, most efficiently bought together as a Business Owner's Policy (BOP). Beyond that core, most states require workers' compensation once the business hires, and a few situational add-ons apply depending on the work.
The question usually arrives at a specific moment. An owner has just signed a lease, won a first contract, or hired an employee. Suddenly it is hard to tell what the law demands from what a salesperson is pushing.
Roughly 36.2 million small businesses operate in the United States, making up 99.9 percent of all US businesses (SBA Office of Advocacy, Frequently Asked Questions About Small Business 2026). This guide sorts the coverage into four groups: the core, the legally required, the situational, and what a typical business can skip. Knowing which is which lets an owner ask for what the business needs, not what a list is selling.
Key Takeaways
Two coverages form the core for almost every small business: general liability and commercial property, usually bundled as a Business Owner's Policy (BOP).
Only workers' compensation (with employees, in every state but Texas) and auto liability for business vehicles are typically required by law.
Situational add-ons like professional liability, commercial auto, cyber, and liquor liability each have a specific trigger. A business needs only the ones its work creates.
A typical low-risk small business can skip most of what appears on a carrier's full list.
The Two Coverages Almost Every Small Business Starts With
Almost every small business starts with the same two coverages: general liability and commercial property.
General liability protects a business from third-party claims: bodily injury, property damage, and personal and advertising injury such as libel or slander. It also includes no-fault medical payments. Its limits are worth knowing early: professional errors, employee injuries, business vehicles, and cyber incidents each sit outside it and need a separate policy.
Commercial property insurance covers the business's own physical assets, such as its building, furnishings, inventory, machinery, and computers, against fire, theft, and other common perils.
According to the Insurance Information Institute, the most common policy for small businesses is the Business Owner's Policy. A BOP bundles property insurance, business interruption (business income) coverage, and liability protection into one policy. It is typically available to smaller businesses, those with fewer than about 100 employees and modest annual revenue.
Consider a neighborhood coffee shop that leases its storefront. It faces two everyday exposures: a customer who slips and is injured, and a kitchen fire that destroys equipment and inventory. General liability answers the first, and commercial property answers the second, which is exactly what a BOP combines.
A BOP is the core, and it deliberately leaves several coverages out. That omission is where the line between required and optional begins.
What's Actually Required, and What Just Feels Required
Only a short list of coverage is truly required by law, and workers' compensation is the clearest example. Workers' compensation is mandated by state law rather than federal law. Once a business has employees, states generally require it, with the trigger commonly set at three, four, or five employees depending on the state.
Texas is the only state where workers' compensation is truly optional for private employers. It also sits outside a BOP everywhere; it is bought as a separate policy.
Auto liability is the other common legal requirement. Most states require it for business-owned or business-use vehicles under financial-responsibility laws. A personal auto policy gives no coverage for a business-owned vehicle.
A second kind of requirement is contractual. Landlords, lenders, and clients frequently require general liability, at specific limits, before a lease, loan, or contract closes. That explains why many owners carry general liability even where no law compels it.
The legally required list is short. The list required to actually operate, often set by a landlord or a client, runs longer. Both are separate from the coverage genuinely worth having.
Situational Add-Ons and the Specific Trigger for Each
Beyond the core and the legal minimums, a handful of add-ons matter only when a business's actual work creates the exposure. Each has a specific trigger:
Professional liability (errors and omissions, or E&O): the trigger is giving advice or professional services, and it covers negligence, misrepresentation, and inaccurate advice that general liability excludes.
Commercial auto: the trigger is owning vehicles or using them primarily for work.
Cyber liability: the trigger is storing customer data or depending on systems to operate. It typically splits into first-party protection for the business's own costs and third-party protection for liability to others.
Liquor liability: the trigger is serving or selling alcohol, common for restaurants.
A bookkeeping office shows how a trigger works. It needs the same general liability and property core as a retail shop, but its real exposure is a client alleging a costly error, which points straight at professional liability.
What a Typical Small Business Does Not Need
Just as important is the coverage a typical small business can skip. A low-risk business with no employees usually has no workers' compensation obligation yet, and sole proprietors and partners are commonly exempt until they hire.
A business with no work vehicles has no commercial auto exposure. A business that gives no professional advice generally has no professional liability exposure either.
Coverages built for larger or more specialized operations are often unnecessary for a simple storefront. Examples include directors and officers, employment practices liability, product recall, and umbrella. A business typically adds them only as it grows into the exposure.
The SBA offers a useful test for the whole decision: "As a general rule, you should insure against things you wouldn't be able to pay for on your own."
That test cuts both ways. It rules out coverage for losses a business could absorb, and it rules in the ones that would end it. Matching coverage to real risk sometimes means buying less, and sometimes means buying more than the legal minimum.
Who Writes the BOP, and Who Places the Rest?
The core and the add-ons usually come from different places, which is why the buying process matters as much as the coverage list.
MGT Insurance is a neo-insurer and the first AI-native full-stack carrier for small commercial property and casualty, built from the ground up for independent agents. Its flagship product is a small-commercial Business Owner's Policy that bundles general liability and commercial property, the same core almost every small business starts with, along with common endorsements.
Workers' compensation and commercial auto sit outside a BOP and are placed through other markets alongside it. Other coverages, such as cyber or professional liability, may be available as add-ons depending on the business, so an agent can confirm what fits.
MGT distributes exclusively through independent agents and never sells direct. An agent shops multiple markets on a business owner's behalf, placing the BOP where it fits and the add-ons wherever they belong.
How a Small Business Owner Actually Buys the Right Coverage
The practical next step is to work with an independent agent. An agent reviews the business's real risks, places the general liability and property core, and adds only the coverages the work triggers. Along the way, the agent shops multiple carriers on the owner's behalf.
Independent agents who want a Business Owner's Policy market built for small commercial can partner with MGT.
Final Takeaway
The four groups in this guide stay stable over time. What changes is which group a business falls into, and it changes at predictable moments: the first hire, the first lease, the first vehicle, the first piece of paid advice. Re-running the sort at each of those moments is the whole discipline, and an independent agent who knows the business can do it in a single conversation.
Small Business Insurance FAQ
What insurance is legally required for a small business?
Workers' compensation once a business has employees, in every state except Texas, plus auto liability for business-owned or business-use vehicles. Landlords, lenders, and clients often require general liability by contract, which is a separate kind of obligation from a legal one. See What's Actually Required for how the two differ.
What does a Business Owner's Policy (BOP) cover?
A BOP bundles general liability, commercial property, and business interruption coverage into one policy, which is why it is the most common policy for small businesses. It is typically available to businesses with fewer than about 100 employees and modest revenue. MGT writes a small-commercial BOP through independent agents. See The Two Coverages Almost Every Small Business Starts With for what each one does.
Does a small business need insurance if it has no employees?
Yes. A business with no employees still typically needs general liability and commercial property, because a customer injury or a fire has nothing to do with headcount. Workers' compensation is usually the one obligation that waits until the first hire. See What a Typical Small Business Does Not Need for what else can wait.
What is the difference between general liability and professional liability?
General liability covers third-party bodily injury and property damage, such as a customer slipping in the shop. Professional liability, also called errors and omissions, covers claims that the business's advice or professional work cost a client money, which general liability excludes. The trigger for the second one is giving advice or professional services at all. See Situational Add-Ons and the Specific Trigger for Each for the other triggers.
