Types of Property and Casualty Insurance: Which Coverage Does Your Business Need?

P&C insurance (property and casualty insurance) is the category of coverage that pays when a business’s own property is damaged or when the business is legally liable for injuring someone or damaging their property. The main commercial types are commercial property, general liability, commercial auto, workers’ compensation, and umbrella or excess liability. Most companies with $20M or more in revenue also carry specialty lines like cyber, professional liability, and D&O on top of that core.

US property and casualty insurers wrote $971 billion in net premiums in 2025, up 4.8%, according to Verisk and the American Property Casualty Insurance Association. For a mid-market buyer the headline matters less than the split underneath it: property is getting cheaper and casualty is not. That split should drive how you renew in 2026.

For businesses with SBA-financed property or equipment, the lender’s hazard insurance requirements specify exactly which P&C coverages must be in place before funding.

What Is P&C Insurance?

P&C insurance is the industry’s name for every non-life, non-health policy that protects against physical loss or legal liability. “Property” covers things you own. “Casualty” covers what you owe other people when something goes wrong. Life, health, and disability insurance sit outside the category entirely.

• What P&C stands for: property and casualty
• Who sells it: P&C carriers such as Travelers, Chubb, The Hartford, and AIG, usually through licensed brokers for commercial accounts
• How it’s regulated: by state insurance departments, which is why workers’ comp rules and auto minimums change at every state line
• How it’s bought at scale: as a program of several policies with coordinated limits, retentions, and renewal dates
• Personal vs. commercial: homeowners and personal auto are P&C too, but commercial P&C is underwritten on payroll, revenue, fleet, and property values

What Are the Types of Property and Casualty Insurance?

There are eight types of property and casualty insurance most mid-market companies need to evaluate: five core lines and three specialty lines. The table shows what each one covers and which way 2026 pricing is moving, based on Marsh’s Q2 2026 US rate data.

Two lines missing from that table show up often in P&C programs: inland marine (equipment and property in transit) and crime or fidelity coverage. Fleet operators should also read our commercial trucking insurance guide, which covers liability, cargo, and physical damage pricing.

What Is the Difference Between Property and Casualty Insurance?

The difference between property and casualty insurance is who suffered the loss. Property insurance pays you when your own assets are damaged or destroyed. Casualty insurance pays other people, and your defense costs, when you’re legally responsible for their injury or loss.

• Property example: a fire shuts down a Houston distribution center for 90 days; property and business income coverage pay to rebuild and replace lost profit
• Casualty example: a delivery driver runs a red light and injures a pedestrian; commercial auto liability pays the claim and the lawyers
• How losses are measured: property losses are capped by values you declare; casualty losses are capped only by the limits you buy
• How long claims take: property claims usually settle in months, while casualty claims can stay open for years
• Why that matters in 2026: the long tail and jury verdicts are exactly why casualty is still rising while property falls

What Is Casualty Insurance?

Casualty insurance is liability coverage: it protects a business against financial loss when it’s held responsible for bodily injury, property damage, or other harm to someone else. General liability, commercial auto liability, workers’ compensation, and umbrella or excess liability are all casualty lines.

Casualty is the harder half of the market right now. General liability and commercial auto were the only major casualty lines still running a net combined ratio above 100 in 2025, according to Triple-I and Milliman, which means insurers paid out more in losses and expenses than they collected in premium on those lines. Litigation costs and claims severity are the drivers. That’s why a clean, well-documented casualty submission is worth far more at renewal than it was five years ago.

What Does Commercial P&C Insurance Include for a Mid-Market Company?

A commercial P&C program for a company with $20M to $200M in revenue usually includes five core policies, an umbrella or excess tower, and three to five specialty lines, all coordinated so limits stack correctly and nothing falls between policies. The structure matters as much as the premium.

• Primary casualty: general liability at $1M/$2M, commercial auto at $1M combined single limit, and workers’ comp with employer’s liability
• Excess tower: $5M to $25M+ of umbrella and excess limits sitting above the primary casualty policies
• Property: blanket limits across locations with business income and contingent business income
• Specialty: cyber, D&O, EPLI, and fiduciary liability for companies sponsoring a 401(k)
• Industry-specific: for firms selling expertise, what mid-market companies pay for professional liability; for publishers and marketers, media liability coverage

Lenders set their own floor. SBA-backed loans, for example, come with SBA hazard insurance requirements that dictate the property coverage in place before closing.

Which P&C Coverages Are Legally Required?

Workers’ compensation and commercial auto liability are the only core P&C coverages most states legally require. Everything else, including general liability, umbrella limits, and property coverage, is driven by contracts, lenders, and landlords rather than statute. In practice those contract requirements are stricter than the law.

• Workers’ compensation: required for employers in nearly every state; Texas is the notable exception, where private employers can opt out as “nonsubscribers” and give up important legal defenses in exchange
• Commercial auto: every state sets a liability minimum, but those minimums are far below what a single serious accident costs, so $1M is the working standard
• General liability: not required by law, but almost every commercial lease, customer contract, and vendor agreement demands proof of it on a certificate of insurance
• Umbrella and excess: large customers, general contractors, and public entities routinely require $5M to $25M of total limits before awarding work
• Property: required by any lender holding a mortgage or equipment loan, with the lender named as loss payee

Multi-state employers carry the added complexity of different workers’ comp rules and benefit schedules in each state where they have employees. That’s one of the first things we check when a company expands from Texas into New York or Florida.

How Is the P&C Market Pricing in 2026?

The P&C market is soft on property and still hard on US casualty in 2026. Marsh’s Q2 2026 Global Insurance Market Index recorded an eighth straight quarter of falling global commercial rates, down 6% on average, but US casualty rates rose 7% and 11% excluding workers’ comp.

Insurers had their best underwriting year in a decade in 2025, but AM Best tied much of it to light hurricane losses and expects margins to tighten in 2026. Read that as a window, not a trend. Property buyers can push for lower rates, higher limits, and lower deductibles now. Casualty buyers should expect the opposite and plan the excess tower accordingly.

How Should a CFO Buy P&C Insurance in 2026?

A CFO should buy P&C insurance as one program with a single renewal strategy, not as a stack of separate policies renewed whenever each one comes due. The goal is to spend property savings where casualty is getting more expensive.

• Align renewal dates so property and casualty go to market together and carriers see the whole account
• Market property aggressively: with rates down double digits, a stale property placement is the easiest money left on the table
• Protect the casualty tower: lock in excess capacity early and don’t let a primary carrier change force a rebuild of every layer above it
• Revisit retentions: a higher workers’ comp or GL retention can offset casualty increases for companies with strong cash flow
• Clean up loss runs and exposure data before submission; underwriters now price casualty on risk quality as much as on class
