Massachusetts Workers' Compensation And Payroll Guide
Massachusetts Payroll And Workers' Compensation Rules
Massachusetts payroll professionals play an important role in workers' compensation administration because payroll records provide important wage, hours, employment, classification, and payment information used to administer workers' compensation claims, calculate benefits, support insurance reporting and audits, and document an employer's compliance responsibilities.
Understanding Massachusetts workers' compensation rules is especially important for payroll professionals who maintain employee records, calculate wages, process payroll after workplace injuries, respond to workers' compensation claims, or provide payroll information to an employer's insurance carrier, third-party administrator, self-insurance program, or the Massachusetts Department of Industrial Accidents.

Massachusetts Workers' Compensation Employer Requirements
Massachusetts generally requires employers operating in the Commonwealth to provide workers' compensation insurance for employees. The requirement applies regardless of the number of employees or hours worked, subject to statutory exceptions.
Massachusetts Workers' Compensation Insurance
Employers generally obtain workers' compensation insurance from an insurance company, insurance agent, or broker. If an employer is unable to obtain coverage through the voluntary market, the Workers' Compensation Rating and Inspection Bureau of Massachusetts administers the assigned risk process. Qualified employers may also seek authorization to self-insure.
Payroll departments should maintain current workers' compensation insurance information, including the carrier, policy information, applicable payroll classifications, and claims administrator contact information. Payroll should coordinate with HR and management whenever employee classifications, work locations, job duties, or payroll arrangements change.
Massachusetts Workers' Compensation Coverage
Massachusetts generally covers employees under its workers' compensation system. The statutory definition of employee is broad, although specific exceptions apply to certain categories of workers.
Corporate officers who own at least 25% of the corporation may request an exemption from workers' compensation coverage. The exemption does not generally extend to employees who are not qualifying corporate officers.
Payroll and HR departments should review worker classifications carefully rather than assuming that part-time status, job title, contract language, or tax treatment eliminates workers' compensation coverage.
Massachusetts Workers' Compensation Coverage For Multistate Employers
Out-of-state employers operating in Massachusetts generally must provide workers' compensation coverage for employees working in the Commonwealth. Employers with employees working in multiple states should review the applicable Massachusetts coverage requirements whenever an employee begins working in Massachusetts or changes work locations.
Payroll departments should maintain accurate records showing where employees perform services. Particular attention should be given to employees who regularly travel between states, relocate, work remotely, or perform services in multiple jurisdictions.

- Employee Claim Filing: A Massachusetts employee generally has up to 4 years from the date the employee becomes aware of a connection between the injury or illness and employment to file a claim with the insurer, subject to statutory rules and exceptions.
- Payroll Information: Payroll should promptly provide accurate wage, hours, employment, and compensation information requested by the insurance carrier or claims administrator.
- Medical Treatment: Payroll generally does not administer medical treatment, but payroll should coordinate with HR and the claims administrator when medical restrictions affect work status, hours, wages, or return-to-work arrangements.
Massachusetts Workers' Compensation Wage Information
Payroll records can be particularly important when a Massachusetts workers' compensation claim involves wage replacement. Massachusetts uses the employee's average weekly wage to determine applicable income benefits.
Average Weekly Wage
The employee's average weekly wage is an important component of Massachusetts workers' compensation benefit calculations. Payroll should maintain complete and accurate records of wages and other compensation that may be relevant to the calculation.
- Maintain complete wage records for the applicable pre-injury period
- Maintain hours-worked records
- Track regular wages
- Track overtime wages
- Track bonuses and commissions
- Track other compensation that may be relevant to the employee's average weekly wage
- Document wage changes before the injury
- Provide accurate wage information to the carrier or claims administrator
- Review wage information for accuracy before submission
Massachusetts Workers' Compensation Benefit Calculations

Massachusetts Workers' Compensation Rates
Workers' compensation insurance premiums and workers' compensation benefit rates are separate concepts. Employer insurance costs depend on applicable classifications, payroll, insurer rates, experience, and other factors.
For injuries occurring on or after October 1, 2025, Massachusetts lists a maximum weekly compensation rate of $1,922.48 and a minimum weekly compensation rate of $384.50. These rates are based on the Massachusetts State Average Weekly Wage and are subject to the applicable date-of-injury rules.
Employers and payroll professionals should verify current Massachusetts workers' compensation benefit rates rather than relying on prior-year schedules.
Massachusetts Workers' Compensation Medical Care
Workers' compensation medical benefits can cover reasonable and necessary medical care for compensable work-related injuries and illnesses. Payroll generally does not administer medical care, but payroll information can become relevant when an employee's medical status affects work hours, wages, modified duty, or return-to-work arrangements.
Payroll should coordinate with HR and the claims administrator when medical restrictions result in changes to an employee's schedule, duties, earnings, or employment status.
Massachusetts Workers' Compensation And Modified Duty
An injured employee may return to work with restrictions when medically authorized. The employee may return to the regular position, a modified-duty position, or another position that complies with applicable restrictions.
Payroll should accurately record regular wages, reduced hours, modified-duty earnings, overtime, bonuses, and other compensation after an employee returns to work. Accurate post-injury earnings can be important when determining applicable workers' compensation benefits.
- Document the employee's return-to-work date
- Track work restrictions through the employer's HR and workers' compensation process
- Track regular and modified-duty hours
- Track post-injury wages
- Track overtime and additional compensation
- Document changes in pay or work schedule
- Provide post-injury wage information when requested by the claims administrator
- Update payroll records when the employee returns to regular duty
How Massachusetts Payroll And Workers' Compensation Work Together
Workers' compensation and payroll are closely connected. When an employee is injured at work, payroll may need to provide historical earnings, hours worked, employment information, wage changes, and post-injury earnings.
Payroll may also become involved when an injured employee:
- Misses work because of a workplace injury
- Returns to work with medical restrictions
- Works reduced hours
- Performs modified or light-duty work
- Receives wages after returning to work
- Receives salary continuation or other employer-paid compensation
- Experiences a change in compensation following an injury
Massachusetts payroll departments should maintain a documented procedure for responding to workers' compensation claims and producing historical payroll and hours-worked information. Payroll should coordinate with HR, management, the employee's supervisor, and the workers' compensation claims administrator when an injury changes an employee's work status or compensation.

Additional Massachusetts Workers' Compensation Resources
Difficult Administrative Areas
Massachusetts workers' compensation administration can become complicated when payroll, human resources, management, medical providers, insurance carriers, third-party administrators, self-insured employers, and the Department of Industrial Accidents must coordinate information across different parts of an employee's claim.
- Determining The Correct Wage Information: Payroll should maintain accurate historical wage and hours-worked information and provide the information requested by the insurance carrier or claims administrator.
- Handling Employees With Multiple Jobs Or Pay Rates: Employees may work different positions, shifts, or jobs with different compensation arrangements. Payroll should maintain clear records showing the employee's wages, hours, duties, and applicable pay rates.
- Tracking Modified-Duty Employees: Payroll should separately document regular wages, reduced hours, modified-duty earnings, overtime, and other compensation after an injured employee returns to work.
- Coordinating Workers' Compensation And Paid Leave: Payroll should maintain clear records of vacation, sick leave, PTO, salary continuation, and other employer-paid compensation during a workers' compensation claim.
- Handling Return-To-Work Changes: Payroll should promptly update records when an employee returns to work, changes hours, performs modified duties, changes compensation, or returns to regular duty.
- Maintaining Accurate Injury And Employment Records: Payroll records should be consistent with HR, timekeeping, employment, and workers' compensation records.
- Managing Insurance Information: Payroll should maintain current carrier, policy, classification, and claims administrator information and should notify the appropriate personnel when coverage information changes.
- Multistate Employees: Employers with workers performing services in multiple states should maintain accurate work-location records and coordinate workers' compensation requirements with HR and the appropriate administrator.
- Responding To Payroll Information Requests: Claims administrators may request detailed wage and hours-worked information. Payroll should establish a standardized process for gathering, reviewing, and transmitting accurate information.
- Protecting Confidential Employee Information: Payroll departments should limit access to employee medical, wage, and workers' compensation information to authorized personnel with a legitimate business need.
- Keeping Procedures And Rates Current: Massachusetts workers' compensation requirements, benefit rates, forms, reporting procedures, and administrative requirements can change. Payroll and HR departments should periodically verify that they are using current Massachusetts requirements.
