Workers’ comp can help limit liability for workplace injuries or illnesses if you meet your legal obligations under state law.1
 
For employees in Massachusetts, workers’ compensation can help cover medical treatment costs if they’re unable to work due to a job-related injury or illness and may provide partial wage replacement after the first five calendar days of disability.2

Is Workers’ Compensation Insurance Required in Massachusetts?

Workers’ compensation insurance in Massachusetts typically covers all employees, with limited exceptions. If you’re actively working as an employee at your own business, you may also need coverage too.
 
There are a few exceptions to note. For example, domestic service employees are typically covered by workers’ compensation coverage only if they work a minimum of 16 hours per week.3 Sole proprietors aren’t required to have workers’ comp coverage unless they have employees.4
 
Massachusetts also requires employers to post proof of coverage in the workplace. This is usually a “Notice to Employees” poster that includes your workers’ compensation carrier’s name.5 The notice should be displayed in a common area and made available in languages your employees can understand.6
 
The Department of Industrial Accidents (DIA) offers an online tool that employees can use to confirm whether a company’s coverage is active and up to date.
