Why no per-state rates here? Massachusetts uses an independent rating bureau (WCRIBMA) whose loss costs are sold to subscribers and brokers. The class codes above use the same NCCI nomenclature, but your binding rate comes from your carrier's filed loss cost multiplier (LCM) applied to those base loss costs.

Filing checklist for Mining & Extraction businesses in Massachusetts

  1. Step 1, Confirm coverage threshold

    any person or business that employs workers must purchase workers' compensation insurance except (i) individuals employing people to do work on their own homes, (ii) non-profit corporations with no paid staff, and (iii) corporations in which each employee is an officer/director who owns at least 25% of the corporation and each has given up his/her right to workers' compensation benefits in the state. For Mining & Extraction operations, this typically applies once you make a first W-2 hire, even part-time.

  2. Step 2, Pick the right class code

    Mining & Extraction businesses typically use codes like 1624, 1164, 1165. The wrong code can cost 4 to 10x more or get reclassified at audit. Across reporting states, Mining & Extraction median rates run $1.66 per $100 with a range of $0.190 to $43.34.

  3. Step 3, Get a quote

    Massachusetts Assigned Risk Pool is one option in Massachusetts; private carriers (Travelers, Hartford, Liberty Mutual, AmTrust) also write coverage. Schedule credits up to 15% are typical for low-loss accounts.

  4. Step 4, Document subcontractors

    General contractors are typically responsible for ensuring subcontractors carry workers' compensation insurance; otherwise, they may be liable for the subcontractor's employees' injuries. Mining & Extraction operators with crews of 1099s should keep certificates of insurance for every sub, otherwise the GC absorbs the sub liability at audit.

  5. Step 5, Annual audit

    Carriers audit payroll within 90 days of policy expiration. Have payroll segregated by class code, job descriptions on file, and overtime properly excluded from rated payroll. Mining & Extraction class allocation can shift if any worker spends more than 50% of time on a different code.

Penalty for non-coverage in Massachusetts: Employers failing to carry required coverage face substantial fines, potential imprisonment, stop-work orders, and direct liability for all injury costs.
