Business Insurance Requirements by State: A Comprehensive Guide

There is no single federal law requiring most private businesses to carry insurance. The regulation of commercial insurance is delegated to individual states under the McCarran-Ferguson Act of 1945. Each state has its own department of insurance (DOI) that sets requirements, approves policy forms, licenses carriers, and handles consumer complaints.

The primary exceptions to state-level regulation are:

• Federal motor carrier insurance — the Federal Motor Carrier Safety Administration (FMCSA) sets minimum insurance requirements for interstate commercial vehicles
• Longshore and Harbor Workers' Compensation Act — federal workers' comp requirements for maritime employees
• Federal Employers' Liability Act (FELA) — covers railroad employees in lieu of state workers' comp
• ERISA — governs employer-sponsored benefit plans, including certain disability and health insurance programs

For the vast majority of small and mid-sized businesses, state law determines what insurance you must carry.

Workers' compensation is the most widely mandated form of business insurance. For a full overview of how this coverage works, see our workers' compensation guide. It provides medical benefits and wage replacement to employees injured or made ill on the job, and in exchange, employees generally give up the right to sue their employer for workplace injuries.

Employee Thresholds by State

States differ significantly in when the workers' compensation mandate kicks in. The threshold is based on the number of employees.

Threshold	States
1 employee (all employers)	AK, CA, CO, CT, DC, DE, HI, IA, ID, IL, KS, KY, LA, MA, MD, ME, MN, NE, NH, NJ, NV, NY, OH, OK, OR, PA, RI, SD, UT, VT, WA, WI, WV, WY
1 employee (construction only, higher for others)	GA (3+ for non-construction), MS (5+ for non-construction), NM (3+ for non-construction)
3+ employees	FL (non-construction; 1+ for construction), GA (non-construction), NC, NM (non-construction), SC
4+ employees	FL (construction at 1+)
5+ employees	AL, MS (non-construction), MO, TN, VA
Voluntary	TX (private employers may opt out)

Note: These thresholds can change as states update their labor laws. Always verify current requirements with your state's workers' compensation board or department of insurance.

Monopolistic State Funds

Four states operate monopolistic state funds, meaning employers must purchase workers' compensation insurance directly from the state fund rather than from private carriers:

• North Dakota — Workforce Safety & Insurance
• Ohio — Ohio Bureau of Workers' Compensation
• Washington — Washington State Department of Labor & Industries
• Wyoming — Wyoming Workers' Compensation Division

In these states, you cannot purchase workers' comp from private insurers. Several other states — including Arizona, Colorado, Idaho, Maryland, Montana, New York, Oklahoma, Oregon, Pennsylvania, and Utah — operate competitive state funds that compete alongside private carriers.

Penalties for Non-Compliance

Failing to carry required workers' compensation insurance exposes your business to severe consequences:

• Fines — range from $1,000 per uninsured employee per day (California) to flat penalties of $10,000–$100,000 (varies by state)
• Criminal charges — classified as a misdemeanor in most states and a felony in some, including California for willful failure to secure coverage
• Stop-work orders — states including Florida, New York, and Georgia can issue immediate stop-work orders that shut down your business until coverage is obtained
• Personal liability — without workers' comp, injured employees can sue you directly, and the exclusive remedy defense is unavailable
• Back premiums — states can assess retroactive premiums for the entire period you were uninsured, plus penalties and interest

Every state requires liability insurance for motor vehicles, and vehicles titled, registered, or regularly used for business purposes must carry commercial auto insurance rather than personal auto policies.

State Minimum Liability Limits

State minimums for commercial auto generally follow the same structure as personal auto minimums but may apply different thresholds. Most states set minimums in the range of:

• Bodily injury per person: $15,000 to $50,000
• Bodily injury per accident: $30,000 to $100,000
• Property damage: $10,000 to $50,000

These minimums are considered dangerously low by most insurance professionals. A single serious accident can generate medical bills, lost wages, and pain-and-suffering claims well into six or seven figures. Most commercial auto policies carry limits of $500,000 to $1,000,000 combined single limit (CSL), and businesses in high-risk industries such as trucking, delivery, and transportation should consider even higher limits or an umbrella policy.

Federal Requirements for Interstate Carriers

Businesses operating commercial vehicles across state lines must comply with FMCSA requirements, which are substantially higher than state minimums:

• General freight (non-hazardous, over 10,001 lbs): $750,000 minimum
• Household goods movers: $750,000 minimum
• Hazardous materials (non-bulk): $1,000,000 minimum
• Hazardous materials (bulk) and certain oil transport: $5,000,000 minimum
• Passenger carriers (16+ passengers): $5,000,000 minimum

Six jurisdictions require employers to provide short-term disability insurance (SDI) benefits to employees who are unable to work due to a non-work-related illness or injury. This is separate from workers' compensation, which covers work-related conditions only.

State/Territory	Program Name	Benefit Duration	Approximate Max Weekly Benefit (2026)	Funding
California	State Disability Insurance (SDI)	Up to 52 weeks	$1,681	Employee-funded (payroll withholding)
Hawaii	Temporary Disability Insurance (TDI)	Up to 26 weeks	$765	Employer-funded (may share 50/50 with employees)
New Jersey	Temporary Disability Insurance (TDI)	Up to 26 weeks	$1,055	Employee and employer contributions
New York	Disability Benefits Law (DBL)	Up to 26 weeks	$170	Employee-funded ($0.60/week cap; employer covers excess)
Rhode Island	Temporary Disability Insurance (TDI)	Up to 30 weeks	$1,007	Employee-funded (payroll tax)
Puerto Rico	SINOT (Seguro por Incapacidad No Ocupacional Temporal)	Up to 26 weeks	$113	Employee and employer contributions

In these jurisdictions, employers must either participate in the state program or provide equivalent benefits through an approved private plan. Non-compliance can result in fines and personal liability for unpaid benefits.

A growing number of states have enacted paid family and medical leave (PFML) laws requiring employers to provide paid time off for family caregiving, bonding with a new child, or dealing with a serious health condition. These programs are funded through payroll contributions — typically shared between employers and employees.

As of 2026, the following states and the District of Columbia have active or approved PFML programs:

• California — Paid Family Leave (PFL), up to 8 weeks, ~60–70% wage replacement
• Colorado — FAMLI, up to 12 weeks, up to $1,100/week
• Connecticut — CT Paid Leave, up to 12 weeks, up to $941/week
• Delaware — Healthy Delaware Families Act, phasing in 2025–2026
• District of Columbia — Universal Paid Leave, up to 12 weeks combined
• Maryland — FAMLI, phasing in 2025–2026
• Massachusetts — PFML, up to 26 weeks combined, up to $1,149/week
• Minnesota — Paid Leave, phasing in starting 2026
• New Jersey — Family Leave Insurance, up to 12 weeks, up to $1,055/week
• New York — Paid Family Leave, up to 12 weeks, 67% of average weekly wage (capped)
• Oregon — Paid Leave Oregon, up to 12 weeks, up to $1,523/week
• Rhode Island — Temporary Caregiver Insurance, up to 6 weeks
• Washington — Paid Family & Medical Leave, up to 18 weeks combined, up to $1,456/week

Employers in these states must register with the state program, collect and remit payroll contributions, and provide required notices to employees. Several additional states have PFML legislation pending or approved for future implementation.

Many states require certain professionals to carry liability insurance as a condition of licensure. These requirements protect consumers and are enforced by state licensing boards.

Professions Commonly Required to Carry E&O or Malpractice

• Attorneys — Oregon is the only state that mandates malpractice insurance for all practicing attorneys. Idaho and Illinois require disclosure of insurance status. Many firms carry coverage voluntarily, as malpractice claims average $30,000–$150,000 in defense costs alone.
• Certified Public Accountants (CPAs) — several states require CPAs to carry professional liability insurance, particularly those practicing in attest services (audits, reviews, compilations). Requirements vary from $100,000 to $1,000,000 in minimum limits.
• Architects and Engineers — some states require professional liability insurance for licensed architects and engineers, while others require disclosure of insurance status to clients. Typical minimums range from $250,000 to $1,000,000.
• Healthcare Providers — physicians, dentists, chiropractors, and other healthcare providers may be required to carry malpractice insurance depending on the state. Seven states — Colorado, Connecticut, Indiana, Kansas, New Jersey, Pennsylvania, and Wisconsin — have mandatory malpractice requirements for physicians. Hospital credentialing committees almost universally require it.
• Insurance Agents and Brokers — some states require insurance professionals themselves to carry E&O coverage, with typical minimums of $100,000 to $500,000.
• Real Estate Professionals — a few states require E&O coverage for real estate agents and brokers, though many brokerages require it as a company policy even without a state mandate.

Beyond professional licensing, certain industries face specialized insurance requirements imposed by state law, regulatory bodies, or standard business practices.

Construction

The construction industry faces some of the most extensive insurance requirements of any sector:

• General liability — required for contractor licensing in most states, typically with minimum limits of $500,000 to $1,000,000 per occurrence
• Workers' compensation — required for construction employers in virtually every state, often at a lower employee threshold than non-construction businesses (e.g., 1 employee in Florida for construction vs. 4 for other industries)
• Surety bonds — most states require contractors to post surety bonds as a condition of licensure. License bond amounts range from $5,000 to $25,000 depending on the state and license class. Performance and payment bonds are required on public works projects exceeding $100,000 under the federal Miller Act, and many states have "Little Miller Acts" with similar requirements.
• Additional insured requirements — general contractors routinely require subcontractors to add them as additional insureds on their GL policies. This is a contractual requirement, not a legal mandate, but it is so universal in construction that it functions as a de facto requirement.

Healthcare

• Malpractice insurance — required by state law or hospital credentialing in most practice settings. Minimum limits typically range from $100,000/$300,000 to $1,000,000/$3,000,000 depending on specialty and state.
• Cyber liability — while not yet mandated by most states, HIPAA's Security Rule effectively requires covered entities to implement safeguards against data breaches. Cyber insurance helps fund breach response obligations including the $100–$50,000 per-violation penalty structure under HIPAA.

Financial Services

• Fidelity bonds — required for broker-dealers under SEC/FINRA rules and for investment advisors in some states
• E&O insurance — required for registered investment advisors in certain states and for insurance agents in others
• Cyber liability — New York's DFS Cybersecurity Regulation (23 NYCRR 500) imposes extensive cybersecurity requirements on financial services companies, and several states have adopted similar frameworks

Transportation

• Commercial auto liability — FMCSA minimums for interstate carriers ($750,000–$5,000,000) plus state requirements for intrastate operations
• Cargo insurance — required for freight carriers, typically $100,000 minimum for general commodities
• Rideshare/TNC insurance — states have adopted tiered insurance requirements for rideshare drivers: personal auto when the app is off, a lower commercial tier when the app is on but no passenger is matched, and full commercial coverage during active rides. Most states require $1,000,000 CSL during active rides.

Given the complexity and frequent changes in state insurance requirements, verifying the current rules for your specific situation is critical. Here is how to do it.

• State Department of Insurance (DOI) — every state has a DOI website with consumer resources, licensing requirements, and regulatory information. Search for "[your state] department of insurance" to find the official site.
• State Workers' Compensation Board — for WC-specific requirements, your state's workers' compensation board or industrial commission provides detailed employer guides, rate information, and compliance resources.
• State Licensing Boards — professional licensing insurance requirements are maintained by the relevant licensing board (e.g., state board of accountancy for CPAs, medical board for physicians).
• State Contractor Licensing Boards — construction insurance and bonding requirements are published by state contractor licensing boards, often with specific checklists for license applicants.
• NAIC (National Association of Insurance Commissioners) — the NAIC website at naic.org provides a directory of state regulators and publishes comparative data on insurance regulation across states.
• Independent insurance agents — a knowledgeable independent agent familiar with your state and industry can be a valuable resource for understanding what coverage is legally required versus what is advisable.
