The insurance types required by law in the United States depend on what you do. Nearly every driver needs auto liability coverage. Every employer owes unemployment taxes from the first hire and, in almost every state, workers’ compensation too. Businesses with 50 or more full-time employees owe health coverage under the Affordable Care Act. Five states add short-term disability. On top of those broad rules, specific activities carry their own mandates: licensed professionals often need malpractice coverage, benefit-plan sponsors need an ERISA fidelity bond, commercial trucking has its own federal minimums, and anyone storing fuel underground must prove they can pay for a leak.
Auto Liability Insurance for Drivers
Forty-nine states require drivers to carry liability insurance before operating a vehicle on public roads. New Hampshire demands only proof that a driver can cover damages after an accident, and Virginia lets drivers pay an annual uninsured motorist fee instead of buying a policy. Everywhere else, an active liability policy is a prerequisite for registering a car.
Minimum coverage amounts vary by state but generally fall in the range of $25,000 to $50,000 for bodily injury per person and $25,000 for property damage. Driving without coverage typically leads to fines, license suspension, and in some states, vehicle impoundment.
How a policy pays out depends on the state’s fault model. In at-fault states, the driver who caused the crash pays for the other party’s losses through their liability policy. About a dozen states use a no-fault system, requiring every driver to carry personal injury protection that covers their own medical expenses regardless of who caused the collision. No-fault rules also limit the ability to sue the other driver unless injuries reach a severity threshold set by the state.
SR-22 Filings After Serious Violations
Drivers who lose their license after a serious violation often need to file an SR-22 certificate of financial responsibility before getting back on the road. An SR-22 is not a separate policy. It is a form the insurer files with the state to prove the driver carries at least the minimum required liability coverage. States commonly require an SR-22 after a DUI conviction, an at-fault accident while uninsured, reckless driving charges, or repeated traffic violations. Most states require the filing to stay in place for about three years, and any lapse during that window restarts the clock or triggers an automatic license suspension.
Commercial Auto Coverage
Businesses that use vehicles for hauling freight or transporting passengers face a federal mandate on top of any state requirement. The Federal Motor Carrier Safety Administration sets minimum liability levels based on cargo and vehicle type. For-hire carriers hauling nonhazardous property in vehicles over 10,000 pounds must carry at least $750,000 in liability coverage. That minimum jumps to $5,000,000 for carriers hauling certain hazardous materials in bulk.1eCFR. 49 CFR 387.9 – Financial Responsibility, Minimum Levels Passenger carriers face similarly steep requirements: $5,000,000 for vehicles seating 16 or more people, and $1,500,000 for smaller vehicles.2eCFR. 49 CFR Part 387 – Minimum Levels of Financial Responsibility for Motor Carriers
A personal auto policy does not cover accidents during business use. If a vehicle is regularly used for deliveries, hauling equipment, or transporting clients, the business needs a commercial auto policy. Even sole proprietors who use a personal vehicle for daily business operations should verify their coverage, because most personal policies explicitly exclude commercial activity. An accident while making a delivery under a personal-only policy can leave the driver entirely uninsured for that claim.
Workers’ Compensation for Employers
Employers in nearly every state must carry workers’ compensation insurance as soon as they hire their first employee. The coverage pays for medical treatment and a portion of lost wages when a worker is injured on the job, and the employee does not need to prove the employer was at fault. Most states make no distinction between full-time and part-time workers when triggering the requirement. A few states set slightly higher thresholds, such as three or five employees, but these exceptions are narrow.
Penalties for operating without coverage are steep. States can issue stop-work orders, impose daily fines that accumulate quickly, and hold the business owner personally liable for an injured worker’s medical costs and lost wages. An uninsured employer typically loses the legal defenses that workers’ compensation was designed to provide, which means an injured employee can sue the business directly for the full extent of their damages, including pain and suffering, rather than being limited to the benefits schedule under workers’ comp. In some states, willfully failing to carry coverage is a criminal offense.
One common way businesses stumble into this liability is by misclassifying workers as independent contractors. Federal labor law uses an “economic reality” test that looks at whether the worker is genuinely running their own business or is economically dependent on the hiring company. The two factors that carry the most weight are how much control the company exercises over the work and whether the worker has a real opportunity to profit or lose money based on their own initiative.3Federal Register. Employee or Independent Contractor Status Under the Fair Labor Standards Act, Family and Medical Leave Act, and Migrant and Seasonal Agricultural Worker Protection Act If an audit reclassifies contractors as employees, the business faces back premiums for every uninsured period, penalties, and exposure to uninsured injury claims. The label on the contract does not control; what matters is how the working relationship actually functions day to day.
Health Coverage for Larger Employers
The Affordable Care Act requires businesses with 50 or more full-time employees (including full-time equivalents) to offer health coverage to their workforce. The IRS calls these businesses “applicable large employers,” and the headcount is based on the prior calendar year’s average.4Internal Revenue Service. Employer Shared Responsibility Provisions Businesses below that 50-person threshold have no federal obligation to provide health insurance, though many do voluntarily.
The coverage has to clear two bars. First, it must provide “minimum value,” meaning the plan covers at least 60% of the total expected cost of covered benefits. Second, it must be “affordable,” meaning the employee’s share of the premium for self-only coverage does not exceed a set percentage of their household income.5Internal Revenue Service. Minimum Value and Affordability Since employers rarely know their workers’ household income, the IRS provides safe harbors based on W-2 wages, rate of pay, or the federal poverty line.
Failing to offer any coverage triggers a penalty of $3,340 per full-time employee for 2026 (minus the first 30 employees).6Office of the Law Revision Counsel. 26 USC 4980H – Shared Responsibility for Employers Regarding Health Coverage Offering coverage that fails the affordability or minimum value test carries a different penalty: $5,010 per employee who ends up getting subsidized coverage through the marketplace instead. These amounts are inflation-adjusted each year and have climbed significantly since the original $2,000 and $3,000 base amounts in the statute.7Internal Revenue Service. Questions and Answers on Employer Shared Responsibility Provisions Under the Affordable Care Act Applicable large employers also file Forms 1094-C and 1095-C with the IRS and furnish Form 1095-C to each full-time employee.8Internal Revenue Service. Instructions for Forms 1094-C and 1095-C
Unemployment Insurance Contributions
Every employer with even a single employee must contribute to unemployment insurance through a combination of federal and state payroll taxes. The Federal Unemployment Tax Act imposes a 6% tax on the first $7,000 of each employee’s annual wages.9Office of the Law Revision Counsel. 26 USC 3301 – Rate of Tax10Office of the Law Revision Counsel. 26 USC 3306 – Definitions Employers who pay their state unemployment taxes on time receive a credit of up to 5.4%, which brings the effective federal rate down to 0.6% for most businesses.
State unemployment tax rates vary widely based on each employer’s claims history. A new business with no layoff record might pay a rate near the state minimum, while a company with frequent turnover could see rates climb to 6% or higher on a wage base that many states set well above the federal $7,000 floor. These funds provide temporary income to workers who lose their jobs through no fault of their own. Falling behind on unemployment tax payments triggers interest, penalties, and potential loss of the state tax credit that keeps the federal rate low.
State Short-Term Disability Insurance
Five states and Puerto Rico require employers to provide short-term disability coverage that protects workers who cannot work because of an illness or injury that happened off the job. California, Hawaii, New Jersey, New York, and Rhode Island all mandate this coverage. The benefit is distinct from workers’ compensation, which covers only workplace injuries. Disability insurance fills the gap by providing partial wage replacement during recovery from non-work-related conditions like surgery, pregnancy complications, or serious illness.
Funding methods differ by state. Some states collect the cost entirely through employee payroll deductions, others split the cost between employer and employee, and a few allow employers to opt into a private plan instead of the state fund. Paid family leave programs are increasingly bundled into these mandates, letting workers take time off for caregiving without losing income entirely. Employers in these states must handle reporting and remittance accurately, because underpayment or failure to enroll triggers penalties from the state agency.
Professional Liability Insurance for Licensed Work
Certain licensed professionals must carry liability insurance as a condition of practicing. This is most common in healthcare: physicians, surgeons, and other medical providers in many states need active malpractice coverage before they can treat patients. Licensing boards treat the policy as assurance that the professional can pay a judgment if a patient is harmed by a clinical error. Lawyers face a related requirement in some jurisdictions, where bar associations either mandate a malpractice policy or require public disclosure to clients that no coverage is in place.
Construction contractors face their own version. Many states will not issue building permits or contractor licenses without proof of general liability coverage or a surety bond. These protect the property owner and the public if the contractor does substandard work, abandons a project, or causes property damage. Public construction contracts almost universally require bonding before a contractor can even submit a bid.
Professionals who carry claims-made policies need to understand what happens when coverage ends. A claims-made policy covers only claims reported while the policy is active. If a professional retires, changes employers, or switches insurers, any claim filed after the policy lapses for work done during the coverage period would be uninsured unless extended reporting coverage, commonly called “tail coverage,” is purchased. Many policies include a short automatic reporting window of 30 to 60 days, but true tail coverage for long-term exposure of past work must be purchased separately, usually within a tight deadline after the old policy expires. Missing that window can leave years of prior work completely uninsured.
ERISA Fidelity Bonds for Benefit Plan Sponsors
Any business that sponsors an employee benefit plan, whether a 401(k), pension, or health plan, must ensure that every person who handles plan funds is covered by a fidelity bond. This is a federal requirement under ERISA, not a state-level mandate, and it applies to fiduciaries, administrators, and anyone else with access to plan assets.11Office of the Law Revision Counsel. 29 USC 1112 – Bonding The bond protects the plan itself against losses caused by fraud or dishonesty. It does not protect the fiduciary personally; that is the role of optional fiduciary liability insurance, a separate product entirely.
The required bond amount equals at least 10% of the plan funds that the person handled in the prior year, with a floor of $1,000 and a general ceiling of $500,000.12U.S. Department of Labor. Protect Your Employee Benefit Plan With an ERISA Fidelity Bond Plans that hold employer securities get a higher ceiling of $1,000,000. For a plan with $2,000,000 in assets, any individual with full access to those funds must carry a bond of at least $200,000. Small employers often do not realize that running a 401(k) makes them subject to ERISA bonding rules. The bond must be in place before the person begins handling funds; retroactive coverage does not satisfy the requirement.11Office of the Law Revision Counsel. 29 USC 1112 – Bonding
Environmental Coverage for Underground Fuel Storage
Businesses that own or operate underground petroleum storage tanks must demonstrate they can pay for cleanup costs and third-party damages if a tank leaks. The EPA sets these requirements at the federal level, and compliance usually means purchasing an environmental liability policy, though alternatives like surety bonds, letters of credit, or reliance on a state cleanup fund may satisfy the mandate.13U.S. Environmental Protection Agency. UST Financial Responsibility
Required coverage amounts depend on the size of the operation. Facilities that market petroleum or pump more than 10,000 gallons per month must carry at least $1,000,000 per occurrence. Smaller operators with lower throughput need a minimum of $500,000 per occurrence. Aggregate annual coverage ranges from $1,000,000 for operators of up to 100 tanks to $2,000,000 for those with more than 100.14eCFR. 40 CFR 280.93 – Amount and Scope of Required Financial Responsibility Gas stations, fuel distributors, and any business with buried petroleum tanks should verify their financial responsibility status with their state environmental agency, which often administers enforcement on the EPA’s behalf.
