A state insurance filing is the submission an insurer sends to a state insurance department to introduce or change its rates, rules or policy forms. Many of these submissions are made through the System for Electronic Rates & Forms Filing (SERFF), the NAIC-operated platform used by insurers and regulators across most US jurisdictions. In practice, rate changes, new products and policy-wording updates frequently leave a regulatory filing record before they reach the market.
A single filing can bundle together everything a regulator needs to review that change: the rate pages or policy forms themselves, supporting actuarial work, and correspondence between the insurer and the department. Understanding one from the outside means opening each of those pieces and fitting them together by hand.
statefilings.ai is built to do that for you: it indexes millions of state insurance filings and lets you ask questions in plain English instead of opening documents one by one. You can connect it to the AI assistant you already use: Claude or ChatGPT, via the statefilings.ai MCP server, or work directly in the web platform.

Think of a state insurance filing as the regulatory case file for a change an insurer wants to make. It carries the change itself, the evidence supporting it, and, where publicly available, a record of the regulator's review. Filings submitted through SERFF follow a broadly recognisable structure.
If you want to work through those sections in the right order, see our guide on how to read a state insurance filing.
Insurers and their filing teams submit regulatory filings when state law or regulation requires them to file rates, rules, forms or related product changes with the insurance department. The process varies by state and product. Some changes require prior approval before use, while others may operate under file-and-use, use-and-file or other regulatory regimes. Either way, the filing creates an official record of what the insurer proposed and how the state handled it.
Most filings fall into three broad families. A rate filing changes prices; a rule filing changes the rules that decide how those prices or underwriting criteria apply; and a form filing changes policy wording. Many submissions combine more than one, which is why filing type is one of the first things worth checking.
Many states make substantial portions of filings publicly available through SERFF Filing Access or other state insurance department resources. Participation, search tools and the exact documents released vary by jurisdiction. SERFF itself is the submission and review system used by insurers and regulators; SERFF Filing Access is one public-facing route into filings that participating jurisdictions make available.
Not everything is public. Certain items, including some actuarial exhibits and proprietary supporting material, can be treated as confidential or withheld from public disclosure. An apparent gap in a public filing can therefore reflect unavailable material rather than a missing document.
For pricing and product teams, filings are one of the clearest public signals of what competitors are doing: where they are raising or cutting rates, which rating factors they are changing, how coverage is evolving and where new products are appearing. For regulatory and compliance teams, they document how changes were submitted and reviewed. Read across companies, states and time, they become a rich source of competitive and market intelligence.
A state insurance filing records an insurer's proposed change to rates, rules or forms in a particular jurisdiction. Many are submitted through SERFF and combine the change itself, supporting evidence and the regulatory review trail into one record, substantial parts of which may be publicly available.
SERFF stands for the System for Electronic Rates & Forms Filing, an electronic system used to submit and review insurance rate, rule and form filings.
SERFF is operated by the National Association of Insurance Commissioners (NAIC) and is used by insurance regulators and filing entities across many US jurisdictions.
No. Many filings are publicly accessible in whole or in part, but availability varies by state and certain supporting documents can be treated as confidential or withheld.
No. SERFF is the system used by insurers and regulators to submit and review filings. SERFF Filing Access is a public-facing service through which participating jurisdictions make filing information available for search.
A rate filing changes prices, a rule filing changes the logic governing how rates or underwriting rules apply, and a form filing changes policy wording. Many submissions combine more than one.
