Every new business needs to answer one question first: what happens financially if something goes wrong. A customer slips in your store, a contractor's laptop with client data is stolen, an employee is injured on the job, or a client claims your work cost them money. Without insurance, each of these comes directly out of your business bank account — and potentially your personal assets if you operate as a sole proprietor. In 2026, with lawsuits and medical costs continuing to climb, a single uncovered incident can end a young business. The good news is that most small businesses are well protected by a short list of core policies, and you can skip the long menu of specialty products until you actually need them.

General liability insurance is the foundation, and for many service businesses it is the only policy they carry in year one. It covers third-party bodily injury, property damage, and advertising injury — for example, a visitor injured at your office or damage you cause at a client's site. Typical costs in 2026 run $40 to $65 per month for small businesses, depending on industry and revenue. Many landlords require it before signing a commercial lease, and a growing number of corporate clients require proof of general liability before awarding contracts. If you interact with customers or clients in person, or do any work on other people's property, this policy is non-negotiable. Even home-based businesses benefit, since homeowners policies exclude business liability.

A business owner's policy, or BOP, bundles general liability with commercial property insurance and business interruption coverage at a discount versus buying each separately. It protects your equipment, inventory, and office space against fire, theft, and vandalism, and the business interruption component replaces lost income if a covered event forces you to close temporarily. BOPs typically cost $80 to $110 per month for small businesses in 2026. Most insurers offer BOPs to businesses with fewer than 100 employees and under about $5 million in revenue, which covers the vast majority of new ventures. If you have a physical location, own meaningful equipment, or hold inventory, a BOP is usually cheaper and simpler than assembling the pieces yourself. Note that BOPs do not cover floods, earthquakes, or professional mistakes — those need separate policies.

Workers' compensation is the policy most new employers misunderstand, because in nearly every state it is legally required as soon as you hire your first employee — and in some states, even for certain contractors. It pays for medical bills and lost wages when employees are injured on the job, and in exchange employees generally cannot sue the business for those injuries. Costs vary enormously by industry: an office worker might cost $40 to $60 per month per employee, while a roofer or construction worker can cost several hundred. Penalties for operating without required workers' comp are severe, including fines that accrue daily and, in some states, criminal charges. If you plan to hire, price workers' comp into your labor budget from day one rather than treating it as a surprise expense.

Errors and omissions insurance, also called professional liability, covers claims that your professional work was negligent, incomplete, or costly to the client. A consultant whose advice leads to a bad business decision, a designer who misses a deadline that delays a product launch, or an accountant who makes a tax error can all face E&O claims — and general liability explicitly excludes these. Typical E&O premiums run $60 to $100 per month for small professional firms in 2026, higher for fields like finance, healthcare, and IT. If your clients pay for your expertise rather than a physical product, E&O is the policy that actually matches your biggest risk. Some client contracts require it, and carrying it signals professionalism when you are competing for work against larger firms.

Beyond the core four, add coverage only when a specific risk or requirement demands it. Commercial auto insurance is required if the business owns vehicles; a personal auto policy excludes business use. Cyber liability, typically $100 to $150 per month, is worth considering if you store customer data, process payments, or would be unable to operate after a ransomware attack — data breach costs have kept rising through 2026. Directors and officers insurance matters once you take outside investment or form a board. Umbrella policies add an extra layer of liability above your other limits for a few hundred dollars a year and are cheap peace of mind for businesses with real exposure. Review your coverage annually, raise limits as revenue grows, and work with an independent agent who can quote multiple carriers — captive agents can only sell you one company's products.
