Department of Industrial Accidents (DIA) Assessment

Chapter 152, Section 65 of the Massachusetts General Laws (as amended by Chapter 572 of the Acts of 1985), established a Workers Compensation Special Fund and a Workers Compensation Trust Fund. The Department of Industrial Accidents is required to collect from each employer, through their insurer, an assessment charge and remit the appropriate amount to the Treasurer of the Commonwealth. The Massachusetts - Assessment Charge endorsement #WC 20 03 02 A will be attached to any policy showing Massachusetts in Item 3.A. of the Information Page.

Prior to July 1st annually, the DIA will release the separate assessment rates - one for Private Employers and one for Public Employers (cities, towns, and other political subdivisions of the Commonwealth).  (Refer to the Table of DIA Assessments for the rates.)

DIA Assessment should be applied to the DIA Standard Premium, at WCRIBMA manual rates, prior to the effects of any approved rate deviation or scheduled rating adjustment. The DIA assessment does not apply to premium developed from Admiralty/FELA classes, classes whose rate has been adjusted to reflect USL&HW exposure, supplemental non-ratable classes, or supplemental rate - atomic energy exposure. Refer to the Massachusetts Voluntary Market Premium Algorithm, Appendix E, or the Residual Market Premium Algorithm, Appendix F

Since the DIA Assessment is not considered to be premium, there is no statistical class code assigned to this charge. The DIA Assessment charge does not need to be reported to the WCRIBMA. The assessment rate applicable at the policy inception date will apply to the full term of the policy.
