Amica Mutual Insurance Company has filed a neutral rate and rule update for its Personal Inland Marine program in Michigan, effective March 1, 2026. The filing affects 998 policyholders and maintains a 0% overall rate impact.

The update revises the Electronic Delivery Billing and Premium Payment Options rule to introduce a new Paid in Full Discount structure and simplify existing discount categories. Policyholders can now receive a 2% discount for choosing all-electronic delivery, a 2% discount for AutoPay via credit card, or a 5% discount for AutoPay via bank draft.

The move, coordinated with a related homeowners filing, underscores Amica’s continued effort to encourage digital adoption and streamline billing processes through electronic and automated payment options.
