Why no per-state rates here? Montana is an NCCI state where loss-cost data is published only to NCCI subscribers, not in public state insurance department filings. 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 Construction businesses in Montana

  1. Step 1, Confirm coverage threshold

    Most employers with one or more employees must carry workers compensation insurance, with limited exceptions (domestic, casual, agricultural under thresholds). For Construction operations, this typically applies once you make a first W-2 hire, even part-time.

  2. Step 2, Pick the right class code

    Construction businesses typically use codes like 7335, 6251, 6252. The wrong code can cost 4 to 10x more or get reclassified at audit. Across reporting states, Construction median rates run $2.26 per $100 with a range of $0.032 to $53.88.

  3. Step 3, Get a quote

    Montana State Fund is one option in Montana; private carriers (Travelers, Hartford, Liberty Mutual, AmTrust) also write coverage. Schedule credits up to 25% are typical for low-loss accounts.

  4. Step 4, Document subcontractors

    General contractor may be held liable for an uninsured subcontractor's workers compensation claims. Construction 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. Construction class allocation can shift if any worker spends more than 50% of time on a different code.

Penalty for non-coverage in Montana: Penalties include fines up to $500 per day, stop-work orders, and personal liability for injured workers' benefits.
