Massachusetts Workers' Compensation Insurance

Who must carry coverage in Massachusetts, how owners and officers are treated, what happens if you go without it, and how to compare carriers.

Massachusetts requires workers' compensation coverage no matter how many employees a business has or how many hours they work; there is no minimum headcount exemption for most employers. A specific carve-out applies to domestic workers, who must work at least 16 hours a week before coverage is required for them. See Mass.gov's workers' compensation insurance requirements page.

Who must carry coverage in Massachusetts

Massachusetts requires workers' compensation coverage no matter how many employees a business has or how many hours they work; there is no minimum headcount exemption for most employers. A specific carve-out applies to domestic workers, who must work at least 16 hours a week before coverage is required for them. See Mass.gov's workers' compensation insurance requirements page.

Owners, officers, LLC members

LLC members, LLP partners, and sole proprietors are not required to carry coverage on themselves, though this exemption never extends to any employees they hire, who must still be covered. Corporate officers who own at least 25% of the corporation can request an exemption for themselves using the state's affidavit of exemption, but again, this doesn't exempt the corporation's actual employees. Because the exemption thresholds differ by entity type (a flat exclusion for LLC members/partners/sole proprietors versus a 25%-ownership test for corporate officers), it's worth confirming which rule fits a given ownership structure before assuming exemption applies.

Independent contractors and subcontractors

Massachusetts applies one of the strictest independent-contractor tests in the country for most purposes, and a hiring business that misclassifies a worker can find itself responsible for that worker's coverage. Collecting a current certificate of insurance from subcontractors before work begins is standard practice in the state.

Penalties for going without coverage

An employer without required coverage can be issued a stop-work order that halts all business operations; paying $100 per day of noncompliance can avoid the order taking effect initially, but that daily penalty rises to $250 per day once the violation is confirmed after a hearing. Separately, failing to provide required coverage is a criminal offense carrying a fine of up to $1,500, up to one year of imprisonment, or both, with a corporation's president or treasurer personally liable; a repeat violation after notice is treated as an additional offense with its own fines and imprisonment. Noncompliant employers can also lose business licenses and permits, face a three-year debarment from state and municipal contracts, and have liens placed against their property for unpaid penalties (M.G.L. c. 152, § 25C).

What injured workers receive

Injured workers receive necessary medical treatment with no dollar cap. Temporary total disability is paid at 60% of the worker's average weekly wage, subject to a maximum reset every October 1 based on 100% of the state average weekly wage (the maximum is $1,922.48 per week for injuries on or after October 1, 2025), with workers earning below the minimum ($384.50) generally receiving their full average weekly wage instead of the reduced percentage. Temporary total incapacity benefits are limited to 156 weeks (three years). Permanent disability and death benefits are calculated separately under Massachusetts's benefit schedule.

How workers' comp is bought in Massachusetts

Massachusetts is a competitive market state rated by its own independent bureau, the Workers' Compensation Rating and Inspection Bureau of Massachusetts (WCRIBMA), rather than NCCI, and our agency can compare coverage across the many private carriers writing business here. There is no Massachusetts state-run workers' comp fund; employers who can't find a voluntary carrier are placed through WCRIBMA's residual market mechanism. Because Massachusetts requires coverage regardless of headcount, even a business with a single part-time employee needs a policy in place from day one.

Massachusetts workers' comp questions

Do I need workers' comp for one part-time employee in Massachusetts?

Yes. Massachusetts requires coverage regardless of employee count or hours worked, with the only hours-based exception applying to domestic workers.

Are Massachusetts LLC members automatically covered?

No. LLC members, LLP partners, and sole proprietors are exempt from coverage on themselves, though any employees they hire must still be covered.

Can a Massachusetts corporate officer opt out of coverage?

Only if they own at least 25% of the corporation; they can then file an affidavit of exemption, but the corporation's other employees still need coverage.

What happens if a Massachusetts employer doesn't carry required coverage?

The state can issue a stop-work order with daily penalties of $100 to $250, plus criminal fines up to $1,500 and up to a year in prison, and the employer can be barred from state and municipal contracts for three years.

How much does an injured worker get paid in Massachusetts?

Generally 60% of average weekly wage, capped at the state average weekly wage, which resets every October 1.

Is there a Massachusetts state fund for workers' comp?

No. Massachusetts doesn't operate its own fund; coverage is placed through the competitive private market or WCRIBMA's residual market mechanism for harder-to-place risks.
