WCF National Insurance Company has filed a two-tier rating structure for California workers’ compensation, creating a new N01 tier with a lower LCM (1.523) aimed at small businesses with estimated annual premium under $25,000. The move, effective January 1, 2026, impacts 899 policyholders and reduces overall rates by 0.7%.

The default N02 tier retains a higher LCM (1.828), while the filing also revises Small Business Pricing (STP) factors, manual rates, and miscellaneous values. The STP credit remains at 30% for accounts under $5,000 in premium, subject to eligibility.

The filing positions WCF National to better compete for California-only small business risks, with WCF Select continuing to serve larger accounts. Exclusions apply to OCIPs, CCIPs, PEOs, staffing companies, roofing, and oil and gas exposures.
