Massachusetts workers' compensation insurance

Massachusetts law requires every business with employees to provide workers’ compensation insurance coverage. Even a company with just one part-time employee must still offer workers’ comp.

What are the requirements for worker's compensation in Massachusetts?

The state’s workers' compensation statute is quite strict: every Massachusetts business with employees must carry workers' compensation insurance.

The only exemptions are for:

  • Domestic service (household) employees who work less than 16 hours per week.
  • Those who work on commission (such as real estate agents) on a buy/sell basis, under contract specifying they’re not employees under federal tax law.
  • Those engaged in interstate/foreign commerce that is covered by federal law for compensation for injury or death.

Do Massachusetts independent contractors need to be covered by workers’ comp?

Workers in the state of Massachusetts are considered employees for tax purposes. This means you will be required to provide them with workers’ comp coverage.

However, if you hire independent contractors, you won’t have to provide them with workers’ comp coverage if you can meet three tests:

  • Prove that they do not work under your direct control or supervision
  • Establish that they perform work that is outside the normal course of your business
  • Document that they have their own independent business or trade doing this kind of work

For more information on working with independent contractors in the commonwealth of Massachusetts, refer to the state attorney general’s advisory.

As a Massachusetts business owner, do I need to include myself under my workers’ comp policy?

In general, business owners must include themselves in their company’s workers’ comp insurance. However, there are three exceptions:

The above individuals can still choose to buy workers’ comp. Health insurance providers can deny medical bills and claims for work-related injuries, which makes buying workers' comp a smart business decision – especially if you work in a risky industry.

Even though certain business owners aren’t required to have their own workers’ compensation coverage, their employees still need coverage.

Are corporate officers required to be covered by a workers’ comp policy?

Corporate officers are considered employees and must have workers’ comp coverage.

One exception applies: corporate officers who own at least a 25% interest in their corporation can file for an exemption with the Massachusetts Department of Industrial Accidents (DIA).

Massachusetts law requires every business with employees to provide workers’ compensation insurance coverage.

What does workers' comp cover for Massachusetts businesses?

Here are several examples of how workers' compensation insurance coverage helps pay expenses for injured workers:

  • A personal care aide develops a back injury from transferring and lifting patients, and can no longer perform their duties. In this instance, workers' compensation would also provide retraining benefits so they could learn the skills to take on a new job.
  • A project manager trips on a cord while visiting a job site and breaks their wrist. Workers' comp covers the cost of the ER visit, surgery, medications, and then two months of physical therapy to help them recover.
  • A general contractor injures their hand while building a home addition. Workers' comp covers their doctor's appointment and pain medication, and provides disability benefits to replace part of the wages they miss while they are recovering.
  • A fast food worker burns themselves while preparing an order for a customer. Workers' comp covers their medical treatment and pain medication.

What does workers' compensation insurance not cover?

Additionally, here's what your workers' comp policy won't cover:

  • Injuries caused by intoxication, drugs, or company policy violations
  • Injuries claimed after a firing or layoff
  • Wages for a replacement worker
  • Occupational Safety and Health Administration (OSHA) fines

How much does workers' compensation insurance cost in Massachusetts?

The average cost of workers’ compensation in Massachusetts is $32 per month.

Workers' compensation insurance companies calculate your premium based on a few factors, including:

  • Payroll
  • Location, such as Boston, Worcester, or Springfield
  • Number of employees
  • Industry and risk factors
  • Coverage limits and exclusions
  • Claims history

How is workers' comp purchased in Massachusetts?

  • Purchase coverage from the state risk market. If a business owner is unable to qualify for a workers’ comp policy, they can buy it from the Massachusetts workers' compensation system or WCRIBMA.. This is the insurance plan of last resort for state employers that can’t find standard coverage due to their extensive number of past workers’ comp claims.

How are workers' comp premiums calculated?

Insurance providers use a specific formula for calculating workers' comp premiums:

Workers' compensation premium calculation formula

Here's a breakdown of this equation:

  • The classification rate reflects your employees' risk. Each worker has a classification code for the type of work they do. Insurers look up those codes in a database to find the associated rate, which is lower for office workers and higher for carpenters, tree trimmers, and others with a higher rate of injuries. Unlike most other states that rely on the National Council on Compensation Insurance (NCCI) database, Massachusetts utilizes their own independent workers' compensation rating and inspection bureau.
  • The experience modification rate (EMR) reflects your business's risk. The average experience modification rate is 1.0, which means a business is similar in risk to others in its profession. Higher EMRs reflect higher risks, such as a history of claims. The EMR only comes into play for annual workers' comp premiums of at least $5,000, so it's not a factor for many small business owners.
  • The insurer multiplies these numbers with your payroll divided by 100 to come up with your workers' compensation rate. Workers' compensation audits are typically done each year to ensure your business pays the right premium for this coverage.

How can Massachusetts business owners save money on workers' comp?

To save money on workers' comp insurance, it's important to make sure you classify your employees correctly. Employees with desk jobs or other jobs with a low risk of injury cost less to insure. This also helps you avoid misclassification fines.

In some cases, small business owners can choose to buy pay-as-you-go workers' compensation. This type of workers' comp policy has a low upfront premium, and lets you make payments based on your actual payroll instead of an estimated payroll. It's useful for businesses that hire seasonal help or have fluctuating numbers of employees.

A ghost policy is a cheap option in some states, however it isn't permitted in Massachusetts. A ghost policy is a workers' comp policy in name only. It provides no protection or medical benefits, but can fulfill contractual requirements for a workers' comp certificate at a reduced price.

Finally, a documented safety program can help lower workers' comp costs. A safer workplace means fewer accidents, which helps keep your premium low.

How does workers’ comp work in Massachusetts?

When an employee suffers a workplace injury or develops an occupational disease, workers' compensation covers the cost of their medical care. It also provides disability benefits while the employee is recovering and unable to work, both for partial disability and total disability. These benefits often compensate lost wages after the first five calendar days of the disability.

Policies usually include employer's liability insurance, which can help cover legal expenses if an employer's worker blames them for an injury. However, the exclusive remedy provision in most workers' comp policies prohibits an employee from suing their employer if they accept workers' comp benefits.

Workers' compensation benefits for injured workers include:

  • Medical expenses (treatment, prescriptions, mileage reimbursement for medical visits)
  • Temporary total incapacity benefits
  • Temporary partial incapacity benefits
  • Permanent and total incapacity benefits
  • Scarring and permanent loss of function and disfigurement
  • Death benefits and burial costs for fatal incidents
  • Vocational rehabilitation services

For details, visit the Mass.gov page on workers' comp benefits.

What are the penalties for not having workers’ comp insurance in Massachusetts?

If you operate your business without workers’ compensation coverage, you may face stiff penalties in Massachusetts.

The state may issue a stop-work order (SWO) if you fail to provide workers’ comp insurance as mandated by state law. This means you will no longer be able to do business in the state.

In addition, you may face minimum fines of $100 per day, including weekends and holidays, for each day you fail to provide coverage. Your penalty bill will accrue daily until you provide insurance and pay your total fine.

If you don’t appeal the SWO, you must shut down immediately and stay closed until you provide workers’ comp coverage and pay your fine. If you decide to appeal the SWO, then you can remain open, but now your fine will increase to $250 per day.

Finally, any uninsured Massachusetts employer loses the ability to compete for public contracts.

Massachusetts workers’ compensation law for death benefits

If an employee dies as a result of a work-related injury or illness, some family members may receive death benefits. These include weekly payments to cover a portion of the deceased employee’s income, along with funeral and burial costs.

Eligible family members include:

  • The deceased worker’s spouse, who must have been living with the person at the time of death
  • A child under age 18 or age 24 if going to school full time
  • A child of any age who is physically or mentally disabled
  • Other family members who fully or partially depended on the deceased worker’s financial support, determined on a case-by-case basis

The deceased worker’s dependent family members will receive death benefits calculated on the basis of the person’s pre-injury weekly pay.

Surviving spouses are eligible to receive weekly payments equaling 66% of the deceased worker’s average weekly wage, but not to exceed the state average weekly wage (SAWW) at the time the worker died.

Spouses are eligible for yearly cost-of-living adjustments (COLAs) once two years pass after the worker’s death.

If a spouse remarries, the deceased worker’s offspring will receive $60 a week, but not to exceed the spousal benefit.

Massachusetts workers’ comp settlements

A workers’ compensation settlement is an agreement between the injured employee, employer, and insurer that will resolve a workers’ compensation claim. This benefits both the employee and the employer.

A settlement in a Massachusetts workers’ compensation claim involves an injured or sick employee giving up the right to receive any future workers’ comp benefits in exchange for receiving a lump-sum payment. Since this involves a worker forfeiting the right to future benefits, the state advises employees to make this decision carefully. It provides a lump-sum brochure to help them make a wise decision.

All employee claim settlements are subject to the approval of an administrative law judge, reviewing board, or other conciliator at the Massachusetts Department of Industrial Accidents.

Massachusetts workers’ compensation statute of limitations

The Massachusetts statute of limitations to file a workers’ compensation claim is within four years of the time employees become aware their employment caused their injury or illness.
