MT| Montana’s Commissioner of Securities and Insurance is requiring all non‑admitted insurers writing Montana business to report policy‑level data via SLIP+ for States beginning with 2026 effective dates, to reconcile insurer-written premium with amounts reported by Montana surplus lines licensees and independently procured insureds. Foreign and domestic insurers must report on a quarterly basis using SLIP+ (with options for manual entry, XML/CSV batch upload, or API), while alien insurers will report annually, and this new framework replaces prior annual-only reporting instructions. Required data elements, drawn from the policy declarations page, include policy number, insured, surplus lines agent or direct procurement filer, the agent’s National Producer Number, 100% of premium for Montana home state policies, and the transaction effective date, with initial 2026 reporting deadlines of June 30, 2026 for 1Q 2026 foreign/domestic business and June 30, 2027 for 2026 alien insurer business, after which ongoing filings follow the stated quarterly and annual schedules.
- Non‑admitted insurers must register and report Montana policies in SLIP+ for States beginning with 2026 business, choosing from manual, XML, CSV, or API submission methods.
- Foreign and domestic insurers file quarterly (June 30, September 30, December 31, and March 31 of the following year), while alien insurers file annually by June 30 for the prior calendar year.
- This notice supersedes prior annual-only reporting instructions and establishes specific reconciliation‑oriented data requirements at the policy level (policy number, insured, surplus lines agent, NPN, full premium, and transaction effective date).
