Essential Business Insurance for Operating a Business in the United States

This guide is written primarily for businesses operating in California as of July 2026. Insurance requirements can differ by state, city, industry, professional license, number of employees, lease agreement, and client contract.

Important Clarification

Many people believe that every business in the United States is legally required to carry General Liability Insurance. That is not completely accurate.

General Liability Insurance is not universally required by law for every type of business. However, it often becomes effectively mandatory when:

State law or an industry license requires it.
A landlord, franchise company, government agency, or client contract requires it.
The business faces significant customer injury, property damage, product, or lawsuit risks.

Forming an LLC or corporation does not eliminate the need for insurance. An LLC may provide some separation between business and personal assets, but it does not protect the owner from every lawsuit, personal act, guarantee, employment claim, or operational loss.

1. Insurance That May Be Legally Required

1. Workers’ Compensation Insurance

In California, a business generally must carry Workers’ Compensation Insurance when it has one or more employees.

This can apply to:

Full-time employees
Part-time employees
Temporary employees
Family members working as employees
Certain workers who may have been incorrectly classified as independent contractors

Workers’ Compensation Insurance can cover:

Medical treatment for work-related injuries
Partial replacement of lost wages
Permanent disability benefits
Rehabilitation and return-to-work assistance
Death benefits for surviving family members

A business with no employees may sometimes qualify for an exemption. However, certain California contractors may be required to maintain Workers’ Compensation Insurance even when they report having no employees.

Operating without required Workers’ Compensation coverage can result in serious penalties, including fines, criminal consequences, license suspension, and direct responsibility for an injured employee’s medical expenses and benefits.

2. Commercial Auto Insurance

A business should carry Commercial Auto Insurance when it owns or regularly uses vehicles for business purposes.

Examples include:

Delivery vehicles
Company cars
Service and repair vehicles
Catering vehicles
Trucks used to transport products or equipment
Vehicles used to transport customers
Employee vehicles regularly used for business errands

California requires vehicles operated or parked on public roads to meet financial responsibility requirements.

Beginning in 2025, California’s general minimum automobile liability limits became:

$30,000 for injury or death to one person
$60,000 for injury or death to multiple people in one accident
$15,000 for property damage

These are only minimum limits. Commercial transportation companies, trucks, passenger carriers, and motor carriers may be required to carry much higher coverage.

A personal auto insurance policy may deny or limit coverage when a vehicle is being used for deliveries, commercial transportation, or regular business activity.

Businesses should discuss the following coverage with their insurance agent:

Commercial Auto
Hired Auto
Non-Owned Auto
Business Use coverage
Employee-owned vehicles used for company business

3. Industry-Specific Liability Requirements

General Liability Insurance is not legally required for every business, but certain licensed industries may have specific insurance requirements.

Examples may include:

Construction contractors
Medical providers
Childcare businesses
Transportation companies
Security companies
Private investigators
Certain financial businesses
Businesses working under government contracts

California contractor LLCs licensed through the Contractors State License Board generally must maintain liability insurance.

A contractor LLC with five or fewer personnel of record generally needs at least $1 million in liability coverage. The required amount may increase based on the number of personnel, up to the applicable maximum.

Contractors may also need:

Contractor license bonds
Workers’ Compensation Insurance
Additional surety bonds
Commercial Auto Insurance
Project-specific insurance

4. Unemployment Insurance and State Disability Programs

Businesses with employees must generally register with the California Employment Development Department and comply with payroll tax requirements.

These programs include:

Unemployment Insurance, paid by the employer
Employment Training Tax, paid by the employer
State Disability Insurance, withheld from employee wages
Personal Income Tax withholding

These programs are handled through payroll and state tax registration rather than through a traditional commercial insurance policy purchased from an insurance broker.

2. Insurance That Is Often Practically Essential

1. Commercial General Liability Insurance

Commercial General Liability, commonly called CGL or General Liability Insurance, is one of the most important policies for almost any business.

It can cover claims involving:

A customer slipping and falling at the business
Damage to a customer’s property
Accidents caused during service or installation work
Injuries caused by a product or completed service
Certain advertising or personal injury claims
Legal defense costs
Settlements and judgments

General Liability coverage commonly includes:

Premises Liability

Covers accidents occurring at the business location, such as a customer falling on a wet floor.

Products Liability

Covers injuries or property damage allegedly caused by products sold or distributed by the business.

Completed Operations

Covers certain injuries or damages that occur after contracted work has been completed.

Common Exclusions

General Liability Insurance usually does not fully cover:

Employee injuries
Commercial automobile accidents
Professional mistakes
Medical malpractice
Liquor-related liability
Pollution or environmental claims
Intentional acts
Cybersecurity incidents
Employment discrimination or wrongful termination
Damage to the business’s own defective work or product

Therefore, business owners should review not only the insurance limit but also the exclusions.

2. Business Owner’s Policy

A Business Owner’s Policy, commonly called a BOP, combines several common coverages into one package.

A BOP generally includes:

General Liability Insurance
Commercial Property Insurance
Business Income or Business Interruption Insurance

A BOP can be useful for:

Retail stores
Offices
Beauty salons
Small restaurants
Professional service businesses
Small warehouses
Home-based businesses with commercial equipment

Workers’ Compensation and Commercial Auto Insurance are normally purchased separately.

3. Commercial Property Insurance

Commercial Property Insurance protects business property such as:

Furniture and fixtures
Computers
Machinery
Restaurant equipment
Inventory
Signs
Tenant improvements
Company-owned buildings
Business supplies

Coverage may apply to losses caused by covered events such as fire, smoke, theft, vandalism, and certain storms.

Business owners should understand the difference between:

Actual Cash Value

Pays the current depreciated value of the damaged property.

Replacement Cost

Pays the cost of replacing damaged property with similar new property, subject to policy conditions.

Flood and earthquake damage are commonly excluded from standard property policies and may require separate coverage.

4. Business Interruption Insurance

Business Interruption Insurance may replace income when a business must temporarily close because of a covered property loss.

It may help pay:

Lost business income
Rent
Certain payroll expenses
Loan payments
Continuing operating expenses
Temporary relocation expenses
Extra expenses required to resume operations

For example, Property Insurance may pay to replace restaurant equipment damaged in a fire. Business Interruption Insurance may help replace the income lost while the restaurant remains closed.

The interruption must normally result from a loss covered by the policy. A general decline in sales is not normally covered.

5. Professional Liability or Errors and Omissions Insurance

Professional Liability Insurance, also called Errors and Omissions or E&O Insurance, is important for businesses that provide professional services, advice, consulting, designs, treatment, or technical work.

Businesses that may need it include:

Doctors and dentists
Medical spas
Veterinarians
Accountants and tax professionals
Real estate professionals
Insurance agents
Marketing agencies
Website developers
Consultants
Architects and engineers
IT service providers
Coaches and instructors

It can cover claims that the business:

Made a professional mistake
Gave incorrect advice
Failed to complete promised services
Missed an important deadline
Caused the client a financial loss
Provided negligent professional treatment

Many Professional Liability policies are written on a claims-made basis. Coverage may depend on when the claim is reported, the policy period, and the retroactive date.

6. Product Liability Insurance

Product Liability Insurance is important for businesses that manufacture, import, distribute, wholesale, or sell products.

It is especially important for:

Food and beverage companies
Cosmetic businesses
Health product companies
Online stores
Importers
Private-label businesses
Retail stores
Product distributors

Product Liability Insurance can respond when a customer claims that a product caused:

Physical injury
Illness
Allergic reaction
Property damage
Burns or other accidents
Contamination-related harm

An importer can be named in a U.S. product liability lawsuit even when the product was manufactured overseas.

Product coverage may be included within a General Liability policy, but the business must confirm that its specific products, ingredients, sales channels, and countries of origin are covered.

7. Employment Practices Liability Insurance

Employment Practices Liability Insurance, commonly called EPLI, protects against certain employment-related claims.

It may cover allegations involving:

Wrongful termination
Employment discrimination
Sexual harassment
Retaliation
Failure to hire or promote
Workplace harassment
Violation of an employment agreement

Workers’ Compensation Insurance covers job-related injuries and illnesses. It does not generally cover wrongful termination, discrimination, or harassment claims.

EPLI is particularly important for restaurants, retail businesses, medical offices, beauty businesses, and companies with frequent employee turnover.

8. Cyber Liability Insurance

Cyber Liability Insurance is increasingly important for any business that stores customer or employee information.

Businesses should consider Cyber Insurance when they:

Accept credit card payments
Operate an online store
Store names, telephone numbers, or email addresses
Use online reservation systems
Maintain medical or patient records
Store employee payroll information
Manage customer websites or social media accounts
Operate membership or review platforms

Cyber Insurance may cover:

Data breaches
Ransomware
System restoration
Customer notification expenses
Credit monitoring expenses
Cyber extortion
Privacy-related lawsuits
Business email compromise
Certain cyber-related business interruption losses

A standard General Liability policy may not adequately cover electronic data or cybersecurity incidents.

9. Commercial Umbrella Insurance

Commercial Umbrella Insurance provides additional liability coverage above the limits of underlying policies.

It may sit above:

General Liability
Commercial Auto
Employers’ Liability
Other approved liability policies

For example, if a General Liability policy has a $1 million limit but a serious accident results in a $2 million covered judgment, an Umbrella policy may cover part of the amount above the underlying policy limit.

Umbrella coverage is particularly valuable for:

Restaurants with many customers
Businesses operating multiple vehicles
Medical and beauty businesses
Childcare and senior care businesses
Construction companies
Businesses hosting large events
Businesses with high customer traffic

Professional Liability or E&O
General Liability or a BOP
Cyber Liability
Media Liability

Workers’ Compensation
Hired and Non-Owned Auto

Subcontractors should also provide valid Certificates of Insurance and required endorsements.

Home-Based Businesses

Home-based businesses should review:

Home-Based Business Endorsement
In-Home Business Policy

4. Important Items to Check Before Purchasing Insurance

A business must accurately disclose its operations to the insurance company.

Important information includes:

Every service provided
Annual revenue
Employee count
Payroll
Business address and square footage
Products and ingredients
Country of manufacture
Online sales
Delivery activities
Alcohol sales
Vehicle use
Subcontractors
Customer data
Previous insurance claims
Additional locations

Failing to disclose an important business activity may lead to coverage disputes, cancellation, or denial of a claim.

Certificate of Insurance

Landlords, clients, government agencies, and contractors often request a Certificate of Insurance, commonly called a COI.

Contracts may require:

Certificate Holder
Additional Insured status
Primary and Non-Contributory coverage
Waiver of Subrogation
Specific liability limits
Products-Completed Operations coverage
Commercial Auto Liability
Workers’ Compensation

A Certificate of Insurance is evidence that a policy exists. It does not automatically add coverage.

When a contract requires Additional Insured status, the business may also need an official policy endorsement.

5. Common Business Insurance Mistakes

“I formed an LLC, so my personal assets are completely protected.”

An LLC does not protect the owner from every personal act, personal guarantee, unpaid wage claim, tax issue, or negligent action.

“General Liability covers every type of accident.”

It does not normally replace Workers’ Compensation, Commercial Auto, Professional Liability, Cyber Insurance, Liquor Liability, or Employment Practices Liability.

“The total policy limit is all that matters.”

Business owners should understand:

Per-occurrence limits
General aggregate limits
Products-completed operations limits
Deductibles
Exclusions
Defense costs
Claims-made versus occurrence coverage

“My personal auto insurance will cover business deliveries.”

Personal policies may exclude or restrict delivery and commercial use.

“The landlord’s insurance covers my inventory and equipment.”

The landlord’s policy generally protects the landlord’s building and liability. It does not normally insure the tenant’s equipment, inventory, improvements, or lost income.

“The cheapest policy is always the best policy.”

A low-cost policy may have serious exclusions, low limits, high deductibles, or restrictions that make it unsuitable for the business.
