Most Tennessee businesses are required by state law to carry only two kinds of insurance, and even those depend on what the business does. A business with five or more employees must carry workers' compensation insurance, which pays for job-related injuries. In the construction trades, that requirement starts at the very first employee. If the business owns or uses vehicles for work, those vehicles must carry auto liability coverage at Tennessee's minimum limits. Almost everything else people think of as "business insurance," such as general liability or commercial property, is not required by Tennessee law at all. It is required by a lease, a client contract, or a lender instead.
What business insurance does Tennessee law actually require?
Tennessee law requires only workers' compensation and commercial auto liability of a general business, and each applies only under certain conditions.
Workers' compensation. Workers' compensation is insurance that pays an employee's medical bills and part of their lost wages when they are hurt or made sick by their job. Under Tenn. Code Ann. Sec. 50-6-102(11), a Tennessee employer with five or more employees is generally required to carry it. The count includes part-time and most family members, not just full-time staff.
Commercial auto liability. Commercial auto insurance covers vehicles a business owns or uses for work. Tennessee sets a minimum liability limit for vehicles on public roads under Tenn. Code Ann. Sec. 55-12-102: 25/50/25, meaning $25,000 for injury to one person, $50,000 for injury per accident, and $25,000 for property damage. A business vehicle has to meet at least that floor. For example, a Chattanooga bakery that buys a delivery van needs auto liability on that van before it hits the road.
That is the full list of what the state itself forces on a general business. The construction industry is the one big exception, and it is worth understanding on its own.
Why does workers' comp start at one employee for construction?
Tennessee treats construction differently from every other industry. Under Tenn. Code Ann. Sec. 50-6-902(a), a business in the construction trades must carry workers' compensation as soon as it has even one employee. The five-employee threshold that applies to a retail shop or a marketing firm does not apply here.
The split matters because it changes the answer for two businesses of the same size. A Memphis roofing company with a single crew member is already required to carry workers' comp, because roofing is a construction trade. A Nashville accounting office with the same single employee is not, because it will not reach the five-employee general threshold until it hires four more people.
This is the detail Tennessee owners get wrong most often. If the work involves building, remodeling, electrical, plumbing, roofing, or similar trades, the one-employee rule is the one that governs.

Required by TN law vs commonly required by contract
The clearest way to think about business insurance in Tennessee is to separate what the state requires from what other parties require. The two lists rarely overlap.
| Coverage | Required by Tennessee law? | Commonly required by | Statute |
|---|---|---|---|
| Workers' compensation (5+ employees, general) | Yes | State | Tenn. Code Ann. Sec. 50-6-102(11) |
| Workers' compensation (1+ employee, construction) | Yes | State | Tenn. Code Ann. Sec. 50-6-902(a) |
| Commercial auto liability (business vehicles) | Yes | State | Tenn. Code Ann. Sec. 55-12-102 |
| General liability | No | Leases, client contracts | Not state-mandated |
| Commercial property | No | Landlords, lenders | Not state-mandated |
| Professional liability (E&O) | No | Client contracts, licensing bodies | Not state-mandated |
The right side of that table is where most Tennessee businesses actually buy coverage. A general contract or a lease can require far more insurance than the state ever will.
What is not required by law but often required by a contract?
These coverages are not mandated by Tennessee statute, yet each is routinely demanded before a business can sign a lease, land a client, or take a loan.
General liability. General liability covers claims that a business hurt someone or damaged their property, such as a customer slipping in a store. Tennessee does not require it. A commercial landlord almost always does. For example, a two-person design firm in Nashville is not legally required to carry general liability, yet its office lease requires it, and its biggest client's contract requires it too. The firm buys the coverage to keep the lease and the account, not to satisfy the state.
Commercial property. Commercial property insurance pays to repair or replace a business's building, equipment, and inventory after a covered event like a fire. A lender financing the building will require it as a condition of the loan. A landlord may require the tenant to insure their own improvements and contents.
Professional liability. Professional liability, also called errors and omissions or E&O, covers claims that a professional's advice or service caused a client financial harm. Accountants, consultants, architects, and similar service providers often face an E&O requirement written directly into their client contracts.
The pattern holds across all three. The obligation comes from a private agreement, so the specific limits and terms are set by that agreement, not by a statute. What a lease or contract requires is a question for a licensed advisor who can read the actual document alongside the business owner.
What does a business owners policy (BOP) bundle together?
A business owners policy, or BOP, is a single package that combines general liability and commercial property coverage, often at a lower cost than buying the two separately. It is built for small and mid-sized businesses with modest risk profiles, such as retail shops, small offices, and many service firms.
A BOP does not include workers' compensation or commercial auto. Those are bought separately. So a Knoxville boutique with three employees and a delivery car could end up with three policies: a BOP for its liability and property, a workers' comp policy once it reaches the five-employee mark, and a commercial auto policy for the car. Our overview of the business owners policy walks through what a BOP does and does not cover.
What is a certificate of insurance, and why do clients ask for one?
A certificate of insurance, sometimes shortened to COI, is a one-page document that proves a business carries the coverage it claims to have. It lists the policy types, the limits, and the dates the coverage is active. It is proof, not the policy itself.
Clients, landlords, and general contractors ask for a certificate before they let a business work or sign a lease. For example, a general contractor in Franklin will usually require a subcontractor to send a certificate showing active general liability and workers' comp before the subcontractor sets foot on the job site. No certificate, no work. The certificate is how the contract requirement gets verified in practice.
What happens if a Tennessee business is underinsured or the insurer fails?
Two protections are worth knowing about, and they work differently.
If a licensed insurance company that issued a policy becomes insolvent and cannot pay, the Tennessee Insurance Guaranty Association may step in to cover certain claims. Under Tenn. Code Ann. Sec. 56-12-107, that coverage is capped at $100,000 per claim for most property and casualty claims. Workers' compensation claims are treated separately and are not subject to that dollar cap.
The guaranty association is a backstop, not a substitute for the right coverage. It only applies if the insurer fails, and the cap can fall short of a large loss. For a business deciding how much coverage to carry and which limits fit its contracts and its risk, that decision belongs with a licensed advisor who knows the specifics of the business.
What should a Tennessee business owner verify?
A short list of things any owner can check against their own situation:
- Employee count and industry. Are there five or more employees, or is this a construction trade with even one? Either answer can trigger the workers' comp requirement.
- Vehicles used for work. Any vehicle owned or used for the business needs to meet Tennessee's 25/50/25 auto liability minimum.
- The lease. Read the insurance clause. It usually spells out a general liability requirement and sometimes a property requirement.
- The biggest client contracts. Look for insurance requirements, including general liability, professional liability, and a certificate of insurance.
- The loan documents. A lender financing property or equipment will state its own insurance conditions.
Each of these is a fact a business owner can confirm on their own. What those facts add up to for a specific business, and what limits fit, is the part a licensed advisor handles case by case.
