Massachusetts Worker’s Compensation Rate Change
Effective July 1, 2023

The Commissioner of Insurance has approved a revision of workers’ compensation rates, effective July 1, 2023, applicable to policies that are new or renew on or after that date. 

The most important items include:

  1. RATE LEVEL DECREASE OF 10.2%
    The overall average decrease of 10.2% in the existing workers’ compensation average rates will vary by class. The average percentage change for Construction Class manual rates is a decrease of 12.5%. A listing of the revised Massachusetts manual rates for the most common construction classifications follows this letter.
  2. EXPERIENCE RATING PLAN CHANGES
    The Experience Rating Plan Expected Loss Rates and D-Ratios will be revised. The State Per Claim Accident Limitation (SPCAL) will remain at $350,000 and the State Multiple Claim Accident Limitation (SMCAL) of $700,000 will continue.
  3. F – CLASSES – OVERALL RATE LEVEL DECREASE OF 15.6%
    The overall average decrease of 15.6% in the existing workers’ compensation F- Class average rates will vary by class.
  4. USL&HW ACT COVERAGE PERCENTAGE APPLICABLE TO NON-F CLASSIFICATIONS
    The loading percentage applicable to USL&HW will be reduced from 19.6% to 16.0% (Multiply a Non-F classification rate by a factor of 1.16 to determine the total rate). Note, you must have USL&HW coverage added to your Workers Compensation policy by separate endorsement for coverage to apply.
  5. SMALL DEDUCTIBLE CREDITS
    The premium credits applicable to the election of small deductibles under either the Massachusetts Benefits Deductible Program or the Massachusetts Benefits Claim and Aggregate Deductible Program will be revised slightly downward.

    2. Loss Constants
    3. Admiralty Law and Federal Employers’ Liability Act classifications
    4. Merit Rating Program
    5. Massachusetts Construction Classification Premium Adjustment Program (“MCCPAP”)
    6. Premium Discount Tables A and B

Experience ratings and ARAP factors (including replacement of preliminary experience ratings and ARAP factors) effective July 1, 2023 and subsequent will be issued in due course using the new rating values.

MCCPAP Factors effective July 1, 2023 and subsequent will be revised in due course using the revised experience rating offset.

Very truly yours,
