Connecticut Small Business Insurance GuideSmall Business Insurance in Connecticut,
Without the Guesswork.

What Connecticut requires

• Workers' compensation: required for Connecticut businesses with one or more employees, full-time or part-time. Sole proprietors aren't required to cover themselves; partners may exclude themselves by notifying the Workers' Compensation Commission in writing. Household employers are required once an employee works 26 or more hours a week.
• Commercial auto: any vehicle registered to the business must carry at least Connecticut's minimum liability limits of 25/50/25 — $25,000 per person and $50,000 per accident for bodily injury, $25,000 for property damage — plus uninsured/underinsured motorist coverage. Those minimums are far too low for a business; $1 million combined single limit is the norm.

Beyond state law, contracts do most of the requiring. Commercial leases, general contractors, municipal and state contracts, and larger clients routinely require specific liability limits, and to be named as an additional insured on your policy. Read those clauses before you sign, not after.

The Business Owner's Policy (BOP)

For most small offices, shops, restaurants and service businesses, a BOP is the most efficient starting point. It bundles:

• General liability — bodily injury and property damage to others, plus personal and advertising injury.
• Commercial property — your building if you own it, or your improvements, equipment, inventory and furniture if you lease.
• Business income — lost income and continuing expenses while you're shut down after a covered loss.

BOPs are priced for smaller, lower-hazard risks. Contractors, manufacturers, larger operations and higher-hazard classes usually need separate general liability and property policies instead.

Commercial auto — the gap in personal policies

Personal auto policies commonly restrict or exclude business use — hauling tools and materials, making deliveries, driving to job sites for pay. If a vehicle is titled to the business, or used heavily for it, it belongs on a commercial auto policy. If employees drive their own cars on company errands, hired and non-owned auto coverage protects the business when it's sued over an accident in a car it doesn't own.

Professional liability, cyber and employment practices

Professional liability (E&O) covers claims that your advice or service caused a client financial harm — the main exposure for consultants, accountants, IT firms, real estate professionals, designers and agencies. General liability does not cover it.

Cyber liability covers the response to a data breach or ransomware attack: forensics, customer notification, credit monitoring, legal defense and business interruption. Any business holding customer names with Social Security, driver's license, account or card numbers has obligations under Connecticut's data breach notification law.

Employment practices liability (EPLI) covers claims of wrongful termination, discrimination and harassment from employees and applicants — worth considering from your first hire.

Commercial umbrella

A commercial umbrella adds $1 million or more on top of your general liability, commercial auto and employer's liability limits. It's often the least expensive way to meet a contract requirement of $2 million or more, and it protects the business from a single catastrophic claim. See umbrella coverage.

Benefits that help you hire

Group health, dental, vision and group life aren't insurance for the business itself, but they're how small employers compete for talent. See our group benefits and small group health pages.

How to keep premiums down

• Classify your operations accurately. Workers' comp and general liability are rated by class code and payroll or sales; the wrong code is expensive either way — too high now, or an audit bill later.
• Estimate payroll and sales carefully and update us when they change, so the year-end audit doesn't surprise you.
• Package where it fits — a BOP usually costs less than buying the same coverage separately.
• Collect certificates from your subcontractors. Uninsured subs can end up on your workers' comp audit.
• Compare carriers. Commercial pricing varies widely by class. As an independent agency we shop 20+ carriers at once.
