The program provides wage replacement benefits and medical coverage to employees who suffer work-related injuries or occupational diseases, regardless of fault.
New Hampshire's workers' compensation framework underwent significant reform in 2005 (Senate Bill 1) and again in 2013 (Senate Bill 1), tightening compensability standards, restructuring the Second Injury Fund, and modifying the definition of disability. These reforms make New Hampshire one of the more heavily reformed workers' compensation systems in the country, with a strong emphasis on objective medical evidence and prevailing factor causation standards.
The Division of Workers' Compensation oversees claims administration, provides mediation services, and adjudicates disputed claims through administrative law judges (ALJs). Appeals from ALJ decisions go to the Labor and Industrial Relations Commission (LIRC), and further appeals proceed to the New Hampshire appellate courts. This administrative system is distinct from the general court system and provides a specialized forum for resolving workplace injury disputes.
Coverage Threshold: All employers with employees | TTD Rate: 60% of AWW | 2025 Max TTD: $1748.00/week | Min TTD: $50.00/week | Statute of Limitations: 2 years (injuries) / 3 years (occupational diseases) | Waiting Period: 3 days (retroactive after 14 days) | Medical Care: Employer-directed initially, employee can request change | Governing Law: NH RSA Chapter 281-A
New Hampshire's maximum TTD rate of $1748.00 per week places it in the mid-range nationally. States like Iowa ($2,106), Connecticut ($1,583), and Washington ($1,520) offer significantly higher maximums, while states like Mississippi ($594.59) and Alabama ($994) have lower caps. New Hampshire's 2005 and 2013 reforms introduced the "prevailing factor" causation standard, which requires that the work injury or occupational disease be the "prevailing factor" (more than 50% of the cause) for the condition — a higher bar than many states that use the "arising out of" standard.
New Hampshire also stands out for its unique Second Injury Fund, which historically provided additional compensation to workers with pre-existing disabilities who suffered subsequent workplace injuries. While the SIF has been significantly restricted by the 2013 reforms, it remains an important feature of the New Hampshire system for claims filed before the reform date.
New Hampshire requires workers' compensation coverage for employers with one or more employees. However, the construction industry has a stricter standard: all construction employers must carry workers' compensation insurance regardless of the number of employees. Understanding these requirements is essential for both employers and employees in New Hampshire.
All regular employees count toward the threshold, including full-time, part-time, and seasonal workers. Corporate officers are considered employees unless they elect to be excluded. Partners and sole proprietors are generally not counted as employees but may elect coverage. The count is based on the total number of employees working for the employer across all locations.
New Hampshire's construction industry mandate is one of the strictest in the country. Every employer in the construction industry must carry workers' compensation coverage, including sole proprietors and independent contractors who are treated as employees for workers' comp purposes unless they maintain their own separate policy. General contractors can be held liable for injuries to workers employed by uninsured subcontractors (the "statutory employer" doctrine). This makes verification of subcontractor insurance critical for general contractors.
New Hampshire does not operate a traditional state-run workers' compensation fund. The New Hampshire Employers Mutual Insurance Company was created as an insurer of last resort but operates as a mutual company rather than a state agency.
New Hampshire workers' compensation provides several categories of benefits to injured workers. The 2005 and 2013 reforms significantly changed how permanent disability is evaluated, moving toward a more medically-driven assessment. Understanding each benefit type and how it is calculated is essential for estimating your potential compensation.
TTD benefits are paid when you are completely unable to work due to your work injury. New Hampshire calculates TTD at 66.67% (two-thirds) of your average weekly wage (AWW), subject to state-imposed minimums and maximums that adjust annually.
| Benefit Parameter | 2025 Rate | Details |
|---|---|---|
| Maximum TTD Rate | $1748.00/week | Based on state AWW |
| Minimum TTD Rate | $50.00/week | Floor for low-wage workers |
| Benefit Rate Formula | 60% of AWW | Two-thirds of average weekly wage |
| Waiting Period | 3 days | Retroactive if disability exceeds 14 days |
| Maximum Duration | Until MMI | No fixed statutory cap in weeks |
| Payment Frequency | Bi-weekly or as agreed | Payments must be timely per DWC rules |
An important feature of New Hampshire's TTD calculation is the Average Weekly Wage (AWW) methodology. New Hampshire calculates AWW by dividing the employee's total earnings during the 13 weeks prior to the injury by 13. If the employee did not work a full 13 weeks, the earnings of a similarly situated employee can be used. Overtime, bonuses, and the reasonable value of benefits (such as room and board) may be included in the AWW calculation.
TPD benefits are paid when you can return to work at reduced hours or in a lighter-duty position, earning less than your pre-injury wage. New Hampshire calculates TPD as 66.67% of the difference between your pre-injury AWW and your current earnings. TPD is subject to the same maximum rate as TTD and continues until you reach MMI or return to full earnings.
PPD benefits compensate for permanent impairment that does not totally prevent you from working. New Hampshire underwent major reforms to PPD calculations in 2005 and 2013. The current system divides PPD into two categories:
Body as a Whole (BAW) Injuries: These are rated based on a disability rating from a physician. Under the 2005 reforms, PPD for BAW injuries is calculated at 60% of AWW multiplied by 400 weeks, with the disability percentage applied. The rating must be based on the AMA Guides (6th edition) or comparable methodology. The "multiplier" system allows consideration of vocational factors, but the 2013 reforms limited the multiplier to 3.5x the rating for injuries sustained after January 1, 2014.
| Body Part | Maximum Weeks | Rate |
|---|---|---|
| Thumb | 60 weeks | 60% of AWW |
| Index Finger | 37 weeks | 60% of AWW |
| Middle Finger | 32 weeks | 60% of AWW |
| Hand | 175 weeks | 60% of AWW |
| Arm | 232 weeks | 60% of AWW |
| Great Toe | 38 weeks | 60% of AWW |
| Foot | 150 weeks | 60% of AWW |
| Leg | 200 weeks | 60% of AWW |
| Eye (loss of sight) | 160 weeks | 60% of AWW |
| Hearing (one ear) | 49 weeks | 60% of AWW |
| Body as a Whole | 400 weeks | 60% of AWW |
PTD benefits are payable when an injury permanently prevents you from engaging in any type of employment. New Hampshire provides PTD at 60% of AWW (subject to the state maximum) for the lifetime of the worker, or until the worker is no longer totally disabled. New Hampshire law creates a presumption of PTD for certain catastrophic injuries including total blindness, loss of both hands, loss of both feet, or any combination of two such losses.
Under the 2005 reforms, PTD determinations must be based on the work injury being the "prevailing factor" causing the total disability. The claimant must prove that they are unable to compete in the open labor market, considering age, education, work history, and the nature of the disability.
When a work-related injury or illness causes death, New Hampshire provides death benefits to surviving dependents. A surviving spouse receives 60% of AWW (up to the state maximum) until death or remarriage. Dependent children receive benefits until age 18, or age 22 if enrolled full-time in school. Total dependents may receive up to 400 weeks of benefits. Burial expenses up to $5,000 are also covered. If there are no dependents, the employer pays $5,000 for burial expenses to the person responsible for the burial.
New Hampshire provides vocational rehabilitation benefits to workers who cannot return to their pre-injury employment. The Division of Workers' Compensation has a Vocational Rehabilitation Unit that can assist injured workers with job retraining, education, job placement services, and other vocational services. The employer or insurer may be required to fund these services when the treating physician determines the worker cannot return to their former position or a comparable one.

Filing a workers' compensation claim in New Hampshire involves specific steps and deadlines governed by Chapter 287 of the Revised Statutes. Understanding the process is critical to protecting your rights and ensuring timely benefit payments.
You must notify your employer of the injury within 30 days of the accident. For occupational diseases, notification must occur within 30 days of when you knew or should have known the condition was work-related. Report in writing if possible and keep a copy. Include the date, time, location, how the injury occurred, and what body parts are affected. While 30 days is the legal deadline, report as soon as possible — delays can raise questions about the legitimacy of your claim.
Get medical treatment immediately. In New Hampshire, the employer or its insurance carrier has the right to direct your initial medical care by selecting the treating physician. Follow all treatment recommendations and attend all appointments. Keep detailed records of all medical visits, prescriptions, and out-of-pocket expenses. If you are dissatisfied with the employer-selected provider, you may request a change through the Division of Workers' Compensation.
Your employer is required to file a First Report of Injury with the Division of Workers' Compensation within 5 days of learning about your injury if it results in more than 3 days off work or medical expenses beyond first aid. This report is filed electronically through the DWC reporting system. You should ask your employer to confirm the report has been filed and request a copy for your records.
If your claim is denied or benefits are not being paid properly, you can file a Claim for Compensation with the Division of Workers' Compensation. You have 2 years from the date of injury (or 3 years for occupational diseases) to file this formal claim. The claim is filed with the DWC and assigned to an Administrative Law Judge (ALJ). It is strongly recommended to hire an experienced New Hampshire workers' compensation attorney to represent you in disputed claims.
If you are experiencing financial hardship due to delayed or denied benefits, you can request a hardship hearing for an expedited determination of TTD benefits. The DWC also offers free mediation services to help resolve disputes without a full hearing. Mediation is voluntary but can significantly speed up resolution of your claim. If mediation fails, the case proceeds to a formal hearing before the ALJ.
New Hampshire employers subject to the workers' compensation law face significant obligations. Failure to comply can result in severe penalties, including criminal charges and personal liability for corporate officers.
Failure to carry required workers' compensation insurance in New Hampshire is a class A misdemeanor, punishable by up to one year in jail and a fine of up to $2,000. Repeat offenses can be charged as a class E felony. Additionally:
It is unlawful for an employer to discharge or discriminate against an employee for exercising their rights under the workers' compensation law. Employees who are retaliated against can file a separate civil action for damages, including reinstatement, back pay, and attorney fees. This protection applies even if the underlying workers' comp claim is ultimately denied.
New Hampshire's workers' compensation system gives employers significant control over medical treatment for work-related injuries. Understanding the medical treatment rules helps injured workers navigate the system and ensure they receive appropriate care.
In New Hampshire, the employer or its insurer has the right to select the treating physician for the injured worker. The employer must provide reasonable and necessary medical care related to the work injury, including:
Under New Hampshire's 2005 reforms, the work injury must be the "prevailing factor" (more than 50% of the cause) of the medical condition for treatment to be compensable. This is a higher standard than many states and means that pre-existing conditions complicate medical treatment decisions. If a doctor determines that a pre-existing condition is the primary cause of your symptoms, the employer may not be required to pay for that treatment.
Either party can request an Independent Medical Examination. The employer/insurer commonly requests IMEs to evaluate the extent of disability, the need for treatment, or whether the worker has reached MMI. The employee also has the right to obtain their own medical evaluation, particularly for permanency ratings. In disputed claims, the ALJ may weigh the credibility of competing medical opinions.
MMI is the point at which your medical condition has stabilized and no further significant improvement is expected from medical treatment. When you reach MMI, TTD benefits end, and you may transition to PPD or PTD benefits if you have permanent impairment. The determination of MMI is made by a physician and can be disputed.
New Hampshire's Second Injury Fund is a unique feature of the state's workers' compensation system that has been significantly reformed over the years. Understanding the SIF is important because it can substantially increase the total compensation available to injured workers with pre-existing disabilities.
The SIF was created to encourage employers to hire workers with existing disabilities. When a worker with a pre-existing disability suffers a new work-related injury that results in a greater overall disability than the new injury alone would cause, the employer's insurer pays only for the disability attributable to the new injury. The SIF pays the additional compensation representing the combined effect of the old and new disabilities.
The 2013 reform legislation (Senate Bill 1) dramatically changed the SIF. For injuries occurring on or after January 1, 2014:
The New Hampshire Second Injury Fund is effectively being phased out for most claims. While existing SIF claims continue to be processed, the dramatic restriction of eligibility for post-2014 injuries means that very few new SIF claims are filed. The SIF remains funded through assessments on workers' compensation insurers and self-insured employers, primarily to pay outstanding pre-reform claims. Workers with pre-existing disabilities who suffer new injuries should consult with an attorney to determine whether any SIF benefits may be available.
New Hampshire has a well-developed administrative system for resolving workers' compensation disputes. The Division of Workers' Compensation provides multiple avenues for dispute resolution, from informal mediation to formal hearings before Administrative Law Judges.
The DWC offers free mediation services for disputed claims. Mediation is voluntary and involves a neutral mediator who facilitates settlement discussions. Mediation can address any disputed issue including medical treatment, TTD payments, permanency ratings, and settlement amounts. The mediator does not issue binding decisions but helps the parties reach a mutually acceptable resolution.
If an injured worker is experiencing financial hardship due to delayed or denied TTD benefits, they can request an expedited hardship hearing before an ALJ. These hearings are scheduled quickly (typically within 30 days) and provide a faster resolution for workers who cannot afford to wait for a full hearing on the merits. The ALJ can order temporary TTD payments pending the full hearing.
When mediation fails or is inappropriate, the case proceeds to a formal hearing before an Administrative Law Judge. The hearing is similar to a trial, with testimony from the injured worker, medical experts, vocational experts, and other witnesses. The ALJ issues a written Award and Decision that can be appealed. Key features include:
After an ALJ issues a decision, either party can file an application for review with the Labor and Industrial Relations Commission (LIRC) within 20 days. The LIRC reviews the record and can affirm, modify, or reverse the ALJ's decision. Further appeal from the LIRC goes to the New Hampshire Court of Appeals within 30 days, and ultimately to the New Hampshire Supreme Court on discretionary review.
Settling a workers' compensation claim in New Hampshire can take several forms, and understanding the options is critical to making informed decisions about your claim.
The most common settlement in New Hampshire is a Stipulation for Compromise Settlement, which resolves the entire claim with a lump-sum payment. This type of settlement requires approval by an ALJ who reviews the terms to ensure they are fair and reasonable. Key features include:
A Stipulation and Award is an agreed resolution where the parties stipulate to specific facts and the ALJ issues an Award based on those stipulations. This type of settlement may leave some issues open, such as future medical care, while resolving others like the permanency rating and associated benefits.
Factors that affect the value of a New Hampshire workers' compensation settlement include:
New Hampshire covers occupational diseases that arise out of and in the course of employment. The work exposure must be the "prevailing factor" (more than 50%) causing the disease. The statute of limitations for occupational diseases is 3 years from the date of diagnosis or when the worker knew or should have known the condition was work-related. Common occupational diseases include repetitive stress injuries, respiratory conditions from workplace exposures, and hearing loss from occupational noise.
New Hampshire has restrictive rules regarding mental health workers' compensation claims. Under the 2005 reforms, mental injuries are only compensable if they result from a traumatic physical injury. "Mental-mental" claims (psychological injuries from workplace stress without a physical injury) are generally not compensable in New Hampshire. This means that claims for PTSD, anxiety, or depression must be connected to a physical work injury to be eligible for benefits.
New Hampshire's "prevailing factor" standard is one of the most significant features of the state's workers' compensation system. To receive benefits, the work injury or occupational exposure must be the "prevailing factor" causing the medical condition and disability. This means:
New Hampshire allows injured workers to pursue third-party claims against parties other than their employer who contributed to the injury. The employer or insurer has a lien against any third-party recovery for workers' compensation benefits paid. New Hampshire follows the "made whole" doctrine, meaning the employer's lien may be reduced if the worker's third-party recovery does not fully compensate for all damages.
New Hampshire uses a multi-factor test to determine whether a worker is an employee or an independent contractor. The key factor is the degree of control the employer exercises over the manner and means of the work. Factors examined include who provides tools and equipment, whether the worker has their own business, the method of payment, and whether the worker can be discharged at will. Misclassified workers may be entitled to workers' compensation benefits.
