Rate Filing

One of the major functions of the Bureau, and the primary responsibility of the Actuarial Department, is the preparation of and procurement of the Workers' Compensation rates for Massachusetts insurers. To a large extent, the rate filing process is governed by statute Section 53A of the Massachusetts General Laws, Chapter 152 provides, in part that:

(1) Any insurance company authorized to transact business in this commonwealth … shall file with the commissioner of insurance, or, if it is a member of or subscriber to a rating organization under section fifty-two C, authorize such rating organization to file with the commissioner on its behalf, its classification of risks and premiums relating thereto and subsequent proposed classifications of premiums.

(2) Such classifications of risks and premiums shall be filed at least every two years and on any additional date that the commissioner of insurance may designate. Within sixty days after any filing the commissioner shall conduct a hearing to determine whether the classifications and rates are not excessive, inadequate or unfairly discriminatory for the risks to which they respectively apply and that they fall within a range of reasonableness."

(For Rating organization information, reference M.G.L., Chapter 152, Section 52C Rating organizations in general; subscribers; co-operative activities; rates; freedom of contract.)

(For more information regarding recent legal/hearing issues refer to Massachusetts Division of Insurance Decisions).
