Is business insurance required by law?

No law requires every business to carry "business insurance." No federal statute makes a private company buy general liability or property coverage. The legal mandates are specific coverages tied to specific facts: workers' compensation once you have employees (set by each state), auto liability on registered vehicles (state minimums, plus federal minimums for interstate for-hire trucking), and a short list of payroll programs, bonds and lender rules. Most of what owners feel is "required" actually comes from a lease, a loan or a customer contract.

What the law requires, coverage by coverage

The rest of this guide walks through the ones that catch owners.

Workers' compensation

Workers' compensation is a state system. The U.S. Department of Labor's own page for the topic points people injured on the job at private employers to their state workers' compensation board (DOL workers' compensation topic page), because the federal compensation programs cover federal employees, longshore workers, coal miners and a few other groups. Whether a private employer must carry coverage, and from how many employees, is therefore a question about your state, and sometimes about your industry.

Two examples show the spread. Florida requires non-construction employers with four or more employees, and construction employers with one or more, to carry comp, counting corporate officers and LLC members as employees, per Florida's Division of Workers' Compensation. Texas goes the other direction: private employers may choose whether to carry workers' comp, and those that opt out ("non-subscribers") must notify their employees and the Texas Division of Workers' Compensation, according to the Texas Department of Insurance. Texas is the best-known state where most private employers can legally opt out; South Dakota's labor department also says no state law requires employers there to carry comp, though uninsured employers can be sued. The practical cost of opting out is the loss of common-law defenses in an injury suit; see texas nonsubscribers: opting out of workers' comp.

Four states, North Dakota, Ohio, Washington and Wyoming, are monopolistic: private insurers may not write comp there, and employers buy from the state fund or qualify to self-insure. Wyoming's mandate is narrower than the others and covers extra-hazardous work listed by statute. See Monopolistic state funds: workers' comp in ND, OH, WA and WY and, for what a monopolistic-state employer needs on top of the state fund, stop gap coverage in monopolistic states.

What happens if you skip it

The consequences vary by state but tend to be severe. In Florida, the department must issue a stop-work order within 72 hours after finding that an employer failed to secure coverage, and the penalty is two times the premium the employer would have paid at approved manual rates for the uncovered period, with a $1,000 minimum, under Fla. Stat. 440.107(7). Other states use fines, criminal penalties, or both. Many states also let the injured employee of an uninsured employer sue in court, without the exclusive-remedy protection that normally limits a worker to comp benefits. Check workers' comp and benefits requirements by state for your state and workers' comp requirements by state: who must carry it for the detail, including who may exclude themselves as an owner or officer (can owners and officers exclude themselves from workers' comp?).

Calling a worker an independent contractor does not remove the obligation if the worker is an employee under your state's test; independent contractors and workers' comp: the misclassification risk covers the risk.

Vehicles

Almost every state requires auto liability insurance on registered vehicles, with minimum limits that are often far below the $1 million that customer contracts ask for. The Insurance Information Institute notes that New Hampshire has no compulsory liability law and requires drivers to demonstrate financial responsibility after an at-fault accident (III). State rules change, so confirm the current minimums with your state's motor vehicle agency or insurance department. Commercial vehicles often face additional rules.

The federal rules are more specific. Under 49 CFR 387.9, for-hire carriers in interstate commerce operating vehicles of 10,001 pounds or more must carry at least $750,000 for general nonhazardous freight. The minimum is $1,000,000 for oil and many hazardous materials, including for private carriers, and $5,000,000 for certain bulk hazardous loads. These minimums have not changed since 1985, and proof is filed through the MCS-90 endorsement or a surety bond. See FMCSA insurance requirements and filings for motor carriers and The MCS-90 endorsement explained: what it guarantees and what it doesn't.

Programs funded by payroll, not by a policy you buy

Several states run short-term disability programs (California, Hawaii, New Jersey, New York, Rhode Island and Puerto Rico), and a growing number run paid family and medical leave funds. In 2026, for instance, Washington's premium is 1.13% of wages up to the Social Security wage cap, Oregon's total contribution rate is 1%, and Colorado's FAMLI premium is 0.88%, each split between employer and employee under that state's rules, according to the states' own agencies. Maryland's contributions begin in January 2027. These are state payroll programs with state-specific registration and filing. state disability and paid family leave programs: every mandate in 2026 has the 2026 detail.

At the federal level, the Affordable Care Act's employer mandate applies to "applicable large employers," those averaging at least 50 full-time employees including full-time equivalents in the prior year. The 2026 section 4980H(a) penalty amount is $3,340 per full-time employee (IRS Rev. Proc. 2025-26). That is a requirement to offer health coverage, not to buy a business insurance policy; see The ACA employer mandate: who must offer coverage and the 2026 penalties.

Required by someone else, not by the law

This is where most small businesses actually run into a mandatory limit.

• Leases. Commercial landlords usually require general liability with the landlord as an additional insured, property insurance for your contents and improvements, and sometimes workers' comp. See insurance requirements in commercial leases.
• Lenders. A bank financing a building requires property insurance. Federal law also bars regulated lenders from making, extending or renewing a loan secured by improved real estate in a designated special flood hazard area unless the building and contents carry flood insurance for the loan term (42 U.S.C. 4012a(b)). SBA 7(a) loans can require life insurance on the principals when collateral falls short; see SBA loans and the life insurance requirement: when it applies.
• Customers and general contractors. Contracts commonly set minimum liability limits, require additional insured status and waivers of subrogation, and ask for certificates. Read how to review the insurance requirements in a contract and test the clause with the contract insurance requirements checker.
• Licensing boards. Some licenses require proof of coverage or a bond. South Carolina, for example, requires on-premises alcohol licensees open after 5 p.m. to carry liquor liability insurance, with credits that can reduce the amount (SC Department of Revenue). Contractor, trucking broker and public-works bonds are the other common cases; see license and permit bonds: who needs one and how they work.
• Franchisors and government agencies. Franchise agreements and government contracts list required lines and limits. See franchise insurance: what franchisors require and why and insurance requirements for government contractors.

Failing one of these requirements is a breach of contract, a defaulted loan covenant or a lost license rather than a legal violation. The result can still be more costly than a fine.

Not required, but costly to skip

General liability, commercial property, cyber, professional liability and employment practices coverage are not required by statute for most businesses. A lawsuit for a customer's injury does not care that you were not required to carry coverage; without it, the defense bill and any judgment fall on the company and, depending on the structure and the facts, on the owner. Forming an LLC does not remove the need; see Does an LLC need business insurance?.

How to confirm what applies to you

1. Count your employees, including part-time, and list the states where they work. Check workers' comp and benefits requirements by state and the state workers' comp agency.
2. List every vehicle, driver and where you travel. Check the state motor vehicle rules and, for for-hire hauling across state lines, FMCSA.
3. Check your license and permit conditions with the issuing board.
4. Read each lease, loan agreement and customer contract for insurance clauses.
5. Take the findings to a licensed agent or broker in your state, and to an attorney where a contract or classification question is unclear. The What business insurance do I need? organizes the list.

Key takeaways

• No single law requires business insurance. The mandates are specific: workers' comp for employees, auto liability for vehicles, and a few payroll programs, bonds and federal rules.
• Workers' comp rules are set by each state, with different thresholds, a Texas opt-out and four monopolistic state funds, so never assume another state's rule applies.
• The penalties for skipping workers' comp can include stop-work orders and a loss of defenses, which makes it the requirement to get right first.
• Leases, lenders, customers and licenses create most of the coverage you are required to carry in practice.
• Coverage that nobody requires, such as general liability and cyber, is often the coverage that matters most in a lawsuit.
