Who needs workers’ comp in Massachusetts?
Massachusetts generally requires employers with one or more employees to carry workers’ compensation insurance—even for part-time staff. Domestic workers are typically covered when working 16 or more hours per week. Out-of-state employers with staff working in Massachusetts must comply with Massachusetts law and show Massachusetts correctly on the policy.
Sole proprietors and partners are usually not covered unless they elect to be included. Corporate officers and LLC members are typically considered employees; certain owners may be able to exclude themselves if they meet statutory criteria and complete the required election, subject to state rules and program underwriting.
Independent contractor status depends on control, direction, and whether the work is an independent trade. Massachusetts applies strict tests (often referred to as the “ABC test” in wage law). If a worker is deemed an employee, you can be liable for benefits if uninsured. General contractors may be responsible for uninsured subcontractors—collect COIs and verify endorsements.
What does Massachusetts workers’ comp cover?
- Medical care for work-related injuries/illnesses
- Wage replacement during lost time (subject to state limits)
- Temporary and permanent disability benefits
- Vocational rehabilitation when eligible
- Death benefits for eligible dependents
In Massachusetts, injured workers generally choose their treating physician. Programs may require utilization review, medical fee guidelines, and preauthorization for certain services. The Department of Industrial Accidents (DIA) uses impartial medical exams to help resolve disputes—your adjuster will confirm next steps.
Unique to Massachusetts: WCRIBMA and impartial exams
– WCRIBMA rating: The Workers’ Compensation Rating & Inspection Bureau of Massachusetts (WCRIBMA) administers classifications, rates, experience rating, and the Assigned Risk Pool (not NCCI). Accurate class coding and payroll allocation are critical to fair premiums.
– Medical choice and impartial exams: Employees typically choose their own doctor. The DIA may order an impartial medical exam during disputes, which can influence benefit decisions.
What does it cost in Massachusetts?
Premium depends on:
- Payroll by WCRIBMA class code
- Claims history and loss trends
- Experience Mod (if eligible)
- Credits/debits, safety programs, and filed rates
Effective rates vary by industry—from under $1.00 to several dollars per $100 of payroll. For accurate pricing, get a quote with current payroll and class details.

Sole proprietors and partners are generally excluded by default but can elect coverage. Corporate officers and LLC members are typically considered employees; certain owners may exclude if they meet Massachusetts criteria and file the required forms, subject to program underwriting.
Who chooses the doctor?
Massachusetts generally allows the injured worker to choose the treating physician. Programs may require utilization review and preauthorization. The DIA may order impartial medical exams during disputes.
Do 1099 contractors need to be covered?

How much does it cost?
Pricing is driven by WCRIBMA class codes, payroll, claims history, and your Experience Mod (if applicable), plus credits/debits. We compare multiple top work comp programs to find competitive Massachusetts rates.
Does Massachusetts use NCCI and Experience Mods?
Massachusetts uses WCRIBMA for classifications, experience rating, and the Assigned Risk Pool (not NCCI). Accurate class coding and audit prep help control premiums.
What is the waiting period and how are wage benefits calculated?
Massachusetts has a 5-day waiting period before wage benefits begin. If disability lasts more than 21 days, benefits may be retroactive to day one. Temporary Total Disability (TTD) is generally about 60% of the average weekly wage, subject to state minimums and maximums.
What posting or notice requirements apply?
Post the Massachusetts workers’ compensation notice and program contact info conspicuously. Provide Form 101 reporting procedures and written instructions to injured employees on how to access care.
What if I’m declined—are assigned risk options available?
Yes. WCRIBMA administers the Massachusetts Assigned Risk Pool for employers who can’t obtain standard coverage. We’ll evaluate assigned risk and other options to secure compliant, cost‑effective coverage.
How do premium audits work?
Most policies are audited annually at term end. Prepare payroll reports and quarterly filings, overtime details, subcontractor COIs, job descriptions by class code, and owner/officer inclusion or exclusion forms.
Multi-state employees — how should I set up my policy?
Ensure Massachusetts is listed properly on your policy (3.A/3.C) when employees live in or regularly work in MA. We configure multi-state coverage so it follows your people and meets WCRIBMA/DIA rules.
What is a “ghost policy” in Massachusetts?
A minimal workers’ comp policy (often excluding owners) used to obtain a COI when there’s little or no payroll. Suitability depends on contract terms and state rules—ask us for compliant options.
Can I get a Waiver of Subrogation or Primary & Noncontributory wording?
Often, yes—subject to program approval and contract specifics. Request early to confirm availability, pricing, and any restrictions (blanket vs. scheduled).
What are the penalties for not carrying coverage?
Penalties can include fines, stop‑work orders, and liability for benefits if an injury occurs while uninsured. Don’t risk operating without coverage.
