What is Prior Approval States? | Definition & Guide
Prior Approval states are US jurisdictions where insurance carriers must submit proposed rate changes to the state department of insurance (DOI) and receive affirmative regulatory approval before implementing new premium rates. Unlike File and Use states (where carriers implement rates upon filing, subject to subsequent DOI review) or Use and File states (where carriers use rates immediately and file within a defined period), Prior Approval states require the DOI to actively review and approve rate filings before the rates can take effect. This regulatory framework adds 90-180 days or more to the rate change timeline, depending on filing complexity, DOI workload, and whether the filing triggers objection letters or requests for additional information. Prior Approval requirements exist across major insurance markets including New York, California (where Proposition 103 adds public hearing requirements for significant rate increases), Texas, and Florida — states that collectively represent a substantial portion of US P&C premium volume. For carriers and InsurTech operators, Prior Approval states create the most significant regulatory time lag between actuarial identification of needed rate changes and market implementation.
Definition
Prior Approval states are US insurance regulatory jurisdictions that require carriers to submit rate filings to the state department of insurance and receive explicit approval before implementing new premium rates. This contrasts with File and Use systems (rates take effect upon filing, DOI reviews afterward) and Use and File systems (rates used immediately, filing follows within a specified period). In Prior Approval states, no rate change — increase, decrease, or structural modification to rating plans — becomes effective until the DOI reviews the filing, evaluates actuarial justification, and grants approval. The DOI review evaluates whether proposed rates are not inadequate, not excessive, and not unfairly discriminatory, the pricing standard that governs insurance regulation across all state frameworks. Major Prior Approval states include New York, California, Texas, Florida, and several others that collectively represent significant portions of nationwide P&C premium volume.
Why It Matters
Prior Approval regulation directly affects how quickly carriers can respond to changing loss conditions. When claims inflation accelerates or catastrophe losses mount, the time between identifying rate inadequacy and implementing corrective pricing is longer in Prior Approval states than in any other regulatory framework. That delay has financial consequences: every policy written or renewed during the approval lag carries premium rates that may understate current risk.
The practical impact varies by state and by the magnitude of the proposed change. Modest rate adjustments (under 5%) in states with efficient DOI review processes may clear approval in 60-90 days. Large rate increases in states with consumer protection mandates face extended review. California's Proposition 103 is the most notable example: rate increases above 7% require public hearings, and the California Department of Insurance (CDI) has historically scrutinized large rate filings closely, sometimes disapproving filings or requiring modifications that result in smaller-than-indicated increases.
For InsurTech companies expanding across states, Prior Approval jurisdictions require more actuarial and compliance resources per state than File and Use jurisdictions. Each Prior Approval state demands a complete filing package through SERFF, actuarial memoranda supporting the rate level, and potentially multi-round correspondence with DOI reviewers who may request additional data or revised calculations. Staffing a compliance function that can manage concurrent filings across multiple Prior Approval states is a material operational cost.
The carrier's relationship with state DOI staff also matters. Regulators who review filings from the same carrier repeatedly develop familiarity with the carrier's actuarial methods, data quality, and filing practices. Carriers that submit well-documented filings with transparent actuarial justification generally experience smoother review processes than carriers that submit minimal documentation or make large rate changes without adequate supporting analysis.
How It Works
Prior Approval regulation operates through a defined review and approval process:
-
Filing submission — The carrier submits a rate filing through SERFF to the state DOI, including proposed rate tables, actuarial memorandum, loss data exhibits, and any changes to rating plans or factor structures. The filing specifies a proposed effective date, though Prior Approval states typically condition the effective date on DOI approval rather than the filing date.
-
DOI review initiation — The DOI assigns the filing to an actuarial reviewer or review team. Review timelines vary by state workload, filing complexity, and whether the filing is for a major line of business (personal auto, homeowners) or a smaller specialty line. Some states have statutory review periods (e.g., 30, 60, or 90 days) within which the DOI must act; others have no statutory deadline, allowing review to extend indefinitely.
-
Objection and information requests — During review, the DOI may issue objection letters identifying concerns with the actuarial methodology, data sufficiency, or rating factor justification. The carrier must respond with additional analysis, revised calculations, or supplementary documentation. This iterative process can extend the review timeline by weeks or months, particularly for large rate increases or filings that introduce new rating variables.
-
Approval, modification, or disapproval — The DOI issues a final decision: approval (rates may be implemented as filed), conditional approval (rates approved with modifications), or disapproval (rates rejected, carrier must refile or maintain existing rates). Disapproval may be followed by a hearing process where the carrier can present its case. Some states allow carriers to implement a partial rate increase while the balance of the filing is under continued review.
-
Rate implementation and monitoring — Upon approval, the carrier implements the new rates in its rating engine for policies effective on or after the approved date. The DOI retains authority to monitor market conduct and may require the carrier to report rate adequacy and market impact data following implementation. In some states, the DOI can reopen a previously approved filing if market conditions or consumer complaints warrant review.
