Massachusetts Workers’ Compensation Law

Massachusetts Workers' Compensation No matter how many employees you have in the state of Massachusetts, you need workers’ compensation coverage. The Massachusetts workers’ comp system helps protect both employees and employers.
For your employees, workers’ comp coverage provides benefits when they get a work-related injury or illness. For your business, workers’ comp limits your liability for workplace injuries or illnesses. Although, in a case of willful negligence by you, your business would not be protected from liability.1
Workers’ comp helps pay for any necessary medical care for work-related injuries or illnesses. It also helps partially compensate employees for lost wages after the first five calendar days of a disability.2
The Department of Industrial Accidents (DIA) administers Massachusetts workers’ compensation law. As an employer in Massachusetts, you have certain obligations under this law. For more information, visit

Massachusetts Workers’ Compensation Insurance Coverage and Rates

Massachusetts Workers' Compensation Law The DIA isn’t responsible for setting workers’ comp rates or class codes, which help determine workers’ comp premiums. Instead, the Workers' Compensation Rating and Inspection Bureau of Massachusetts (WCRIBMA) sets these rates and codes.3
As of July 1, 2018, the bureau recommended an 11.1% decrease in average rates for industrial classes and an 11.5% rate decrease for F-Classes. 4
For more information, visit the WCRIBMA’s website.
What’s covered? The Massachusetts Workers’ Compensation Act requires you to cover all workers at all times, covering:
  • Medical care for work-related injuries or illnesses
  • Partial wage replacement when your employees need time off to recover
Coverage requirements state you’ll need workers’ comp coverage for all your employees, regardless of how much time they work each week. You’ll also need it for yourself if you work as an employee at your business.
Domestic service employees are the only exception and need to work a minimum of 16 hours per week for workers’ comp coverage.6 Sole proprietors do not need to get workers’ comp coverage, unless they have employees.7
