Workers comp cost in New Hampshire comes down to three things: how much payroll you run, the type of work your employees do, and your claims history. New Hampshire does not set one fixed rate that every insurer must charge. The rating bureau NCCI files advisory loss costs, and each insurer then adds its own factor on top, so shopping matters. As of mid-2026, New Hampshire loss costs have been falling, with an average 6.1 percent cut approved for 2026, so it is a good time to compare carriers.
Who this is for: New Hampshire employers who have to carry workers comp and want to understand what sets the price and how to keep it down.
The short version
- Premium is roughly your payroll, divided into 100-dollar units, times a rate for each type of work.
- The category your work falls into for pricing, often called the class code, moves the price the most.
- A score built from your past claims, the experience modification rate, raises or lowers your price.
- Insurers file their own rates on top of the bureau's loss costs, so two carriers can quote you differently.
- As of mid-2026, New Hampshire loss costs have been trending down, the latest in a long run of yearly cuts.
What drives your price
| Factor | What it means | Effect on cost |
|---|---|---|
| Payroll | Your total wages, counted in 100-dollar units | More payroll, more premium |
| Type of work (class code) | A category for the risk of your work | Roofing costs far more than clerical |
| Claims history (experience modification rate) | A score from your past claims | A good record lowers it, a bad one raises it |
| Carrier | Each insurer files its own rate on top of the loss costs | Shopping can change the price meaningfully |
How New Hampshire sets rates
New Hampshire is a private, competitive market with no state fund. It uses the national rating bureau, NCCI, which files advisory loss costs that the Insurance Department reviews. Those loss costs are the starting point for the risk of each kind of work; each insurer then applies its own factor and files its own final rates, competing openly, which is why quotes vary between carriers. As of mid-2026, the Insurance Department approved an average 6.1 percent reduction in voluntary loss costs effective January 1, 2026, and the assigned risk pool dropped about 5.4 percent, the latest in a multi-year run of reductions. Treat exact percentages as a moving target and confirm the current filing when you shop.
How to keep the cost down
The two levers you control most are your classification and your claims. Making sure each employee is placed in the correct type-of-work category matters, because a wrong category can overcharge you for years. Keeping claims down improves the score built from your history, which directly lowers your rate. Reporting your payroll accurately at audit avoids surprise bills. And because insurers price differently on top of the same loss costs, comparing carriers at renewal is one of the simplest ways to make sure you are not overpaying, especially while loss costs are drifting down.
A Londonderry trucking example
Illustrative, not a quote. A trucking company near Londonderry with a dozen drivers gets a renewal that looks high. When we review it, part of the payroll for office staff was rated at the higher driving category by mistake, inflating the premium. We correct the classification, confirm the company's claims score is applied correctly, and shop the account against several carriers. The corrected classes and a fresh set of quotes bring the price down without cutting any coverage, helped by loss costs that have been falling. See our workers comp for trucking page.
Real questions New Hampshire owners ask
How is workers comp priced in New Hampshire?
It is based on your payroll counted in 100-dollar units, a rate for your type of work, and a score from your claims history. Each New Hampshire insurer files its own rate, so prices vary between carriers.
Why is my price so different from the shop next door?
Usually your type of work and who you buy from. The category your business falls into for pricing, often called the class code, captures how risky the work is and moves the price most, so a roofer pays far more than an office. Each insurer also files its own rate.
If I have a claim, does my price go up next year?
It can. A score built from your past claims, called the experience modification rate, raises or lowers your price. A clean history pulls it below average and lowers your cost, while claims push it up the following year.
Are New Hampshire workers comp rates going up or down?
As of mid-2026, they have been trending down. The state approved an average 6.1 percent cut in voluntary loss costs for 2026, and the assigned risk pool dropped about 5.4 percent, the latest in a long run of cuts.
Does New Hampshire set one rate all insurers must charge?
No. The rating bureau NCCI files advisory loss costs, but each insurer sets and files its own rate on top of them. That is why two carriers can quote the same business quite differently.
How can I lower my workers comp cost?
Make sure employees are in the correct type-of-work category, keep claims down to improve your score, report payroll accurately at audit, and compare carriers at renewal since insurers price differently.
Why did my premium change at audit?
New Hampshire comp premium is based on actual payroll, so if your wages were higher than estimated, the audit trues up the premium. Correct classifications and accurate estimates reduce audit surprises.
Why New Hampshire owners choose Morrow
- We shop the right market for you. In New Hampshire you buy workers' comp on the open market from any private carrier licensed in the state, because there is no state fund, and if no carrier will take you the NCCI-run assigned risk plan is the guaranteed fallback, so we can shop your rate freely and still have a backstop for hard-to-place work.
- We catch pricing mistakes. Your price depends heavily on the category your work falls into for pricing (the class code). Put people in the wrong category and you overpay for years. We review your payroll and classifications before you buy.
- Proof of coverage, fast. Need a certificate (proof of coverage) for a general contractor or a landlord before Monday? We turn those around the same business day for most carriers.
- We help lower the score that drives your price. Insurers give you a score based on your past claims that raises or lowers your cost (the experience modification rate). We review it each year, flag errors, and connect you with return-to-work and safety resources that bring it down.
- Real people when a claim happens. When someone gets hurt, we stay involved through the life of the claim, not just at renewal.
