Insureon’s small business customers in Massachusetts pay a median of $44 a month for general liability, close to the national $45, though Boston brings dense, expensive commercial property, high medical costs, and a litigation market that carriers price alongside New York’s. Massachusetts also asks more of employers than most states do, since its workers’ compensation rule catches almost every business with a single hire. Below are the 2026 numbers by coverage, trade and headcount, what shapes them, and the levers that move a Massachusetts premium. For the 50-state picture, see average business insurance cost by state.
Average business insurance cost in Massachusetts by coverage
The table shows what a Massachusetts business of two to five people in a middling risk class pays for the three policies most small businesses carry. Professional liability, also sold as errors and omissions, responds when a client says your work cost them money. A business owner’s policy adds property cover on your own equipment.
| Coverage | Typical monthly | Typical annual | What it covers |
|---|---|---|---|
| General liability ($1M per occurrence) | $29–$59/mo | $348–$708/yr | Third-party injury and property damage; the policy a client or landlord asks for by name. |
| Professional liability (E&O) | $73–$147/mo | $876–$1,764/yr | Claims that your advice or work cost a client money, legal defence included. |
| Business owner’s policy (BOP) | $49–$98/mo | $588–$1,176/yr | General liability plus commercial property, usually with business-interruption cover. |
| Hiscox advertised starting price | from $22.50/mo | from $270/yr | E&O from $22.50, general liability from about $29, a BOP from about $42. |

Most Massachusetts businesses begin with general liability because somebody else demands it: a Back Bay landlord in Boston who wants a certificate before handing over keys, or a Worcester property manager who will not let a cleaning crew into a building without one. A business owner’s policy earns its higher price once you own equipment, stock or a lease, because it bundles property cover for less than two separate policies. Our guide to general liability vs professional liability vs BOP explains which to buy first.
Massachusetts business insurance cost by trade
Your trade moves the premium more than your address: a consultant who never leaves the laptop is a cheaper risk than a contractor, and insurers price that gap with a risk class. Twelve common trades in Massachusetts, two to five people, $1M/$2M limits.
| Trade | General liability | Business owner’s policy |
|---|---|---|
| Consultant | $21–$42/mo | $36–$72/mo |
| IT or software developer | $24–$48/mo | $27–$54/mo |
| Accountant or bookkeeper | $20–$39/mo | $35–$71/mo |
| Photographer or videographer | $19–$38/mo | $28–$55/mo |
| Real estate agent | $22–$43/mo | $34–$68/mo |
| Online store (e-commerce) | $27–$55/mo | $56–$112/mo |
| Personal trainer or fitness | $19–$38/mo | $35–$70/mo |
| Cleaning or janitorial | $31–$63/mo | $45–$90/mo |
| Landscaping or lawn care | $33–$66/mo | $55–$111/mo |
| Auto repair shop | $35–$70/mo | $88–$176/mo |
| Restaurant or café | $92–$184/mo | $148–$296/mo |
| General contractor | $106–$211/mo | $49–$98/mo |
Estimates from Insureon’s published medians for each business type for Massachusetts, for two to five people at the standard $1M/$2M limits. Not quotes.
Insureon publishes no separate figure for roofing and other high-risk construction, so they are left out of the table. Near the cheap end of it, one trade has its own Massachusetts guide: software developer insurance in Massachusetts.
Cost by business size
Headcount matters too: every hire is another pair of hands that can drop a client’s server or leave a wet floor unsigned, and Insureon says more staff and more revenue generally mean higher premiums. It publishes no prices by headcount, so the table below only shows where in the Massachusetts range a business of each size is likely to sit.
| Business size | General liability |
|---|---|
| Just me | $29–$44/mo |
| 2 to 5 people | $29–$59/mo |
| 6 or more people | $44–$59/mo |
Estimates from Insureon’s published medians for Massachusetts, not quotes. No source publishes prices by headcount, so we show the lower half of the range for a one-person business under $100k in revenue, the whole range for two to five people, and the upper half for six or more. Larger businesses often pay more than this, especially for workers’ comp.
Business insurance cost in Boston, Worcester, Springfield, Cambridge and Lowell
No source publishes prices by city, so our estimate is statewide: a Boston business and a Springfield business get the same estimate of $29–$59 a month for the same trade, size and limits.
| City | General liability | Local licensing office |
|---|---|---|
| Boston | $29–$59/mo | City of Boston Clerk’s Office, Business Certificate (DBA) |
| Worcester | $29–$59/mo | Worcester City Clerk, Business Certificate (DBA) |
| Springfield | $29–$59/mo | Springfield City Clerk, Business Certificate (DBA) |
| Cambridge | $29–$59/mo | Cambridge City Clerk, Business Certificate (DBA) |
| Lowell | $29–$59/mo | Lowell City Clerk, Business Certificate (DBA) |
Statewide estimate from Insureon’s published medians for Massachusetts, not a quote; no source publishes prices by city. Local clerk’s offices shown are where a sole proprietorship or partnership files its DBA, not where you buy insurance.
None of these five cities carries a distinct weather premium the way a hurricane-exposed Gulf Coast market does, so a Boston, Worcester or Cambridge business should expect a quote close to the statewide $49–$98 BOP range above rather than a city-specific surcharge.
Why Massachusetts costs what it does
Insureon’s Massachusetts customers pay a median of $44 a month for general liability, close to the national $45, and three forces shape Massachusetts premiums.
- Dense, expensive commercial property around Boston. Greater Boston packs a large share of the state’s small businesses into some of the priciest commercial real estate in the Northeast, which loads the property half of a BOP more heavily than in a state with cheaper, more spread-out cities.
- High medical costs. A slip on your floor is settled at local medical prices, and Massachusetts, home to some of the country’s most expensive hospital systems, runs above the national norm. Higher severity per claim shows up directly in the liability rate.
- A competitive Northeast litigation market. Carriers price Massachusetts alongside New York and the rest of the Northeast corridor, and that proximity raises the expected cost of defending a claim, which is part of what a liability premium buys.
What Massachusetts requires
The Massachusetts Division of Insurance (DOI) regulates insurers. Workers’ compensation is required for nearly every employer as soon as they have one employee, including most corporate officers of a company, and is administered under the state system by the Department of Industrial Accidents (DIA). There is no small-employer exemption to sit under.
Trade registration is separate again. Home improvement contractors register with the Office of Consumer Affairs and Business Regulation (OCABR) as a Home Improvement Contractor, and anyone supervising construction work needs a Construction Supervisor License (CSL) from the Board of Building Regulations and Standards. Licensing rules change, so confirm current specifics with the body named before you rely on this page.
How to lower your premium in Massachusetts
These are the levers that most often bring a Massachusetts premium down.
- Get the classification right. A bookkeeper rated as a general consultant pays for a risk they do not carry, so describe the work precisely.
- Quote real revenue. Premiums scale with revenue, and quoting projections means overpaying until renewal.
- Buy the limits the contract asks for, not more. $1M/$2M satisfies nearly every Massachusetts lease and vendor agreement; see $1 million liability insurance cost for what higher limits add.
- Take a higher property deductible. Boston’s dense commercial property sits on the property side of a BOP, and lifting that deductible is the most direct way to bring the property half down.
- Bundle into a BOP. If you need property cover at all, a BOP is almost always cheaper than two separate policies.
- Stay claims-free and pay annually. Carriers price a clean loss history lower at renewal, and most charge less for one annual payment than for twelve.
Where these numbers come from
The figures at the top of this page and in the main cost table come from the same data as our cost estimator, so the two always agree. The starting point is the median premium that Insureon, an online insurance agency, publishes for its small business customers (see its Massachusetts page). We adjust it for the state using Insureon’s state medians, and show the band that Insureon’s own price distribution says most businesses fall in. Every figure is an estimate, not a quote. The full method and source list is on the estimator page.
Frequently asked questions
How much is business insurance in Massachusetts per month?
A Massachusetts business of two to five people typically pays about $29–$59 a month for general liability, $73–$147 for professional liability and $49–$98 for a business owner’s policy.
Is business insurance more expensive in Massachusetts than the national average?
About the same. Insureon’s small business customers in Massachusetts pay a median of $44 a month for general liability, against $45 nationally, so a two to five person business typically pays about $29–$59 a month here against $30–$60 nationally. Dense, expensive commercial property around Boston, high medical costs and a competitive Northeast litigation market can push individual premiums up, especially for a business owner’s policy.
Do I need workers’ compensation in Massachusetts?
Yes, almost every Massachusetts employer needs it as soon as they have one employee, including most corporate officers. It is administered under the state’s workers’ compensation system by the Department of Industrial Accidents and sits outside the policies priced on this page.
How much does $1 million liability insurance cost in Massachusetts?
A $1 million per occurrence, $2 million aggregate general liability policy costs a typical Massachusetts business of two to five people about $29–$59 a month, or $348–$708 a year. That is the limit most landlords and contracts ask for; a one-person business under $100k in revenue pays closer to $29–$44 a month.
What is the cheapest business insurance in Massachusetts?
General liability on its own is the cheapest policy for most Massachusetts businesses, and desk-based businesses such as a one-person consultancy are among the cheapest to insure. Insureon’s figures put general liability for a one-person consultancy in Massachusetts at about $21–$31 a month.
How much is business insurance in Boston?
The same as anywhere else in Massachusetts: about $29–$59 a month for general liability for a two to five person business; no source publishes prices by city, so our estimate is statewide. Boston, Worcester, Springfield, Cambridge and Lowell all fall under the same statewide range.
