Massachusetts Workers’ Compensation: Benefits, Filing, and Deadlines

Massachusetts workers’ compensation benefits cover the full cost of medical treatment for a job-related injury or illness, replace a portion of your lost wages, pay a lump sum for certain permanent injuries, fund vocational retraining, and provide survivor benefits if a worker dies. The system runs under Chapter 152 of the Massachusetts General Laws and is administered by the Department of Industrial Accidents (DIA).¹ For injuries on or after October 1, 2025, the maximum weekly benefit is $1,922.48, and the payments are exempt from both federal and Massachusetts income tax.²

Who Qualifies

Nearly every worker in Massachusetts is covered. Employers must carry workers’ compensation regardless of size or hours worked, and full-time, part-time, and seasonal employees all qualify. The only statutory carve-out is for domestic workers who put in fewer than 16 hours per week.³ The injury or illness has to be tied to your job, but that link doesn’t require a single accident. Repetitive stress injuries, occupational diseases, and conditions caused by workplace exposures all qualify.

Independent contractors sit outside the system, but Massachusetts uses a strict three-part test. To be classified as a contractor, the worker must (1) perform the work free from the employer’s direction and control, (2) do work outside the employer’s usual course of business, and (3) run their own independent trade or business doing that kind of work. All three prongs must be met, or the worker is legally an employee entitled to benefits.⁴ If you’ve been called a contractor but the arrangement doesn’t clear all three, you may still have a claim.

Medical Benefits

The insurer must pay for all reasonable and necessary medical treatment related to your work injury: hospital care, surgery, prescriptions, physical therapy, prosthetic devices, and follow-up care. You pay nothing out of pocket, and medical coverage continues as long as treatment is needed, even after weekly wage benefits have run out.⁵

You generally pick your own doctor. The one catch: if your employer participates in a preferred provider arrangement, your first appointment can be required with a provider in that network. After that, you can choose your own treating physician and switch once. If that physician refers you to a specialist, you can also switch to a different specialist in the same field once. Emergencies allow more flexibility.⁵

Expect the insurer to request an independent medical examination (IME) at some point, particularly on expensive claims. The IME is performed by a doctor the insurer selects, and the resulting report is often used to challenge benefits. That is different from an evaluation under the DIA’s Impartial Physician Program, where a neutral doctor examines you and the report carries significant weight with the administrative judge. An insurer-selected IME does not carry that same presumption of neutrality.

Weekly Wage Replacement

Massachusetts pays wage replacement at three levels based on how severely your injury limits your ability to work. Each level has its own rate and duration, and time on one can count against the time available on another.

Temporary Total Incapacity (Section 34)

If you can’t work at all, you receive 60% of your gross average weekly wage, including overtime and bonuses. The benefit is capped at the state’s maximum of $1,922.48 per week for injuries on or after October 1, 2025. If your average wage falls below the minimum rate of $384.50, you receive your full average wage instead.⁶² Section 34 has a hard ceiling of 156 weeks (three years). After that, you either shift to partial incapacity benefits or, if the disability is permanent, to Section 34A.

Temporary Partial Incapacity (Section 35)

If you can work but earn less than before, you receive 60% of the difference between your pre-injury average weekly wage and what you can currently earn. This benefit is capped at 75% of what your Section 34 benefit would have been. Section 35 alone runs for up to 260 weeks.⁷

The combined duration matters. If you received both Section 34 and Section 35 benefits for the same injury, the combined total generally can’t exceed 364 weeks. That combined cap extends to 520 weeks if you have suffered a permanent loss of 75% or more of a bodily function listed in the statute (such as an arm, leg, or eyesight) or you developed a permanently life-threatening condition.⁷

Permanent Total Incapacity (Section 34A)

Workers whose injuries leave them permanently unable to work receive two-thirds of their pre-injury average weekly wage, subject to the same maximum and minimum rates. Section 34A benefits begin after Sections 34 and 35 are exhausted and continue for the duration of the disability with no week limit.⁸

Lump Sum for Permanent Impairment

Separate from weekly wage payments, Section 36 provides a one-time lump sum for specific permanent injuries. The amount equals the state average weekly wage at the time of injury multiplied by a set number of weeks assigned to each body part. Examples from the schedule:

Loss of dominant arm: average weekly wage × 43 weeks
Loss of dominant hand at the wrist: average weekly wage × 34 weeks
Loss of one eye: average weekly wage × 39 weeks
Loss of hearing in both ears: average weekly wage × 77 weeks
Loss of both eyes: average weekly wage × 96 weeks

At the current maximum rate of $1,922.48, loss of a dominant arm comes to roughly $82,667. Partial losses receive a proportional share. These payments are on top of any weekly incapacity benefits.⁹

Survivor Benefits

When a work-related injury or illness causes an employee’s death, the insurer pays benefits to surviving dependents. A surviving spouse receives two-thirds of the deceased worker’s average weekly wage, capped at the state average weekly wage and with a floor of $110 per week. An additional $6 per week goes to each dependent child under 18, or older if the child is a full-time student or physically or mentally unable to earn a living.¹⁰

If the surviving spouse remarries, weekly benefits stop. Each dependent child then receives $60 per week, though the total can’t exceed what the spouse had been receiving. If there is no surviving spouse, the children split the full benefit equally. Burial expenses are also covered.¹⁰

Vocational Rehabilitation

Workers who can’t return to their previous job because of their injuries may receive vocational rehabilitation services: skills assessment, job training, education, and placement assistance. The insurer pays. These rights survive settlement. A lump sum agreement cannot buy out your entitlement to vocational benefits, and if you have been deemed suitable for vocational rehabilitation, no settlement can proceed without written consent from the Office of Education and Vocational Rehabilitation.¹¹

How to File and Get Paid

Report the injury to your employer as soon as you can, preferably in writing. The statute says notice must be given “as soon as practicable.” Once your employer knows, they must file a First Report of Injury (Form 101) electronically with their insurer and the DIA within seven calendar days (excluding Sundays and legal holidays) after your fifth day of full or partial disability. Those five days don’t have to be consecutive.¹²

From the moment the insurer receives that report, it has 14 days to either start paying benefits or send a written denial to you, your employer, and the DIA. If the insurer misses the 14-day window, it owes you a $200 penalty. Going 60 days without acting adds a $2,000 penalty to the DIA’s special fund, and that jumps to $10,000 at 90 days.¹³

The Four-Year Deadline

You have four years from the date you first became aware of the connection between your injury or illness and your employment to file a formal claim. For occupational diseases that develop over time, the clock starts when you knew (or reasonably should have known) about the work connection, not when the exposure began. If the worker dies, the four years run from the date of death.¹⁴ Once you file or the insurer starts paying, the statute of limitations is tolled for additional benefits related to that injury. Missing the four-year deadline can permanently bar the claim.

If Your Claim Is Denied

File an Employee Claim (Form 110) with the DIA. If the form is complete, the DIA schedules a conciliation, an informal meeting where a DIA conciliator tries to bring both sides to agreement.¹⁵ If that doesn’t resolve the case, it moves to a conference before an administrative judge, who issues a temporary order. Either side has 14 days to appeal that order and request a full hearing, where the judge takes testimony and medical evidence and issues a written decision. Further review runs to the DIA Reviewing Board and, rarely, to the Massachusetts Appeals Court.¹⁶

Lump Sum Settlements

Section 48 lets injured workers settle their claims for a lump sum, with limits. A lump sum settlement is only valid if the employee has returned to continuous employment for six months or more, or has completed a vocational rehabilitation program. And even when a settlement is reached, it cannot buy out your right to future medical benefits or vocational rehabilitation.¹⁷

Medicare adds another layer. If you are a current Medicare beneficiary and the settlement exceeds $25,000, or you expect to enroll in Medicare within 30 months and the settlement exceeds $250,000, the Centers for Medicare and Medicaid Services recommends submitting a Workers’ Compensation Medicare Set-Aside (WCMSA) proposal. The set-aside reserves funds for future injury-related medical costs Medicare would otherwise cover, protecting you from losing Medicare coverage for those treatments.¹⁸

Attorney Fees

You do not pay your attorney out of pocket in most situations. When an insurer denies or delays your claim and you prevail, the insurer pays your attorney’s fee. The DIA publishes a fee schedule updated each October 1. As of October 1, 2025:

Insurer agrees to pay before conference: $1,375.37 plus expenses
Employee wins at conference: $1,964.82
Employee prevails at hearing: $6,876.85 plus expenses
Employee prevails on appeal to the Reviewing Board: $1,964.82

Administrative judges can adjust these amounts based on case complexity and attorney workload. If the insurer’s written settlement offer matches the judge’s order, no attorney fee is owed by the insurer. These fees are paid by the insurer and do not come out of your benefits.¹⁹

Taxes and SSDI

Workers’ compensation benefits paid under Massachusetts law are fully exempt from federal income tax. The IRS excludes all amounts received as workers’ comp for an occupational sickness or injury, including payments to survivors. One exception: if you retire and receive pension or retirement benefits tied to age or length of service rather than the workplace injury, those payments are taxable even if the injury prompted your retirement.²⁰ Massachusetts does not tax workers’ compensation benefits at the state level either.

If you collect both workers’ compensation and Social Security Disability Insurance (SSDI), federal law caps your combined benefits at 80% of your average earnings before you became disabled. When the total exceeds that threshold, Social Security reduces your SSDI payment to bring the combined amount back within the limit. The reduction continues until your workers’ comp ends or you reach full retirement age, whichever comes first.²¹ If you are negotiating a lump sum settlement while receiving SSDI, structuring the settlement to spread over your expected lifetime rather than as a single payment usually results in a smaller monthly reduction to SSDI.

Protection Against Retaliation

Massachusetts law prohibits employers from firing, refusing to hire, or otherwise punishing an employee for filing a workers’ compensation claim, testifying in a proceeding, or cooperating with a DIA investigation. If your employer retaliates, you can file a lawsuit in Superior Court. A court that finds a violation can order the employer to pay lost wages, reinstate you to a suitable position, and reimburse your attorney fees.²² Anti-retaliation protection does not apply if the employee knowingly participated in a fraudulent proceeding, and a collective bargaining agreement with different terms on this issue controls.
