44% of Rate Filings Draw a Regulator Objection, and the Delays Are Enormous
Of the 20,183 approved rate filings ZestyAI analyzed, 8,776, exactly 44%, received at least one formal objection from a state Department of Insurance. That wave of pushback generated more than 35,000 individual objection letters in a single year.
Here is the part that should alarm any driver renewing a policy: an objection added a median 38 days to the approval process. That is 38 days during which a carrier cannot legally charge the rate it believes the risk requires. The insurer either absorbs the mismatch or delays market entry entirely.
Bryan Rehor, Senior Director of Regulatory and Government Affairs at ZestyAI, put it plainly:
"The real story in this data is how avoidable the delays are. Many of the questions causing delay are not new; they recur from filing to filing."
That recurrence is the key word. These are not novel regulatory challenges stumping carriers for the first time. They are the same questions, appearing in the same states, filing after filing, adding weeks or months each time they go unanswered at the point of submission.
The report concludes that these delays are largely predictable and often avoidable, which makes the systemic scale of 35,000 objection letters in one year all the more striking.
How Much Longer an Objection Actually Takes: By Line of Business
The penalty for drawing an objection varies significantly depending on what type of insurance is being filed. Personal Auto carries the harshest time cost on a relative basis.
| Homeowners | 4,297 | 53.2% | 13 days | 56 days | Wisconsin: under 1 day | New York: 220 days |
| Personal Auto | 6,339 | 50.7% | 9 days | 52 days | Wisconsin: under 1 day | California: 246 days |
| Commercial Property | 9,547 | 34.3% | 7 days | 33 days | Wisconsin: under 1 day | California: 252 days |
Personal Auto filings that clear without objection close in a median of just 9 days. Add one objection letter and that median jumps to 52 days, nearly six times as long. Homeowners filings stretch from 13 days clean to 56 days objected. Commercial Property, the least-contested line at a 34.3% objection rate, still sees approval times climb from 7 days to 33 days when regulators push back.
The takeaway for you as a consumer: every week a carrier spends waiting for regulatory sign-off is a week its pricing is out of sync with actual loss trends. Carriers typically compensate on the next filing cycle, often with a larger rate request than they would have needed otherwise.
Wisconsin vs. California: Why Your State Matters More Than Your Line of Business
The single most powerful predictor of how long a rate filing takes is not whether it covers homes or cars. It is which state regulator reviews it.
ZestyAI's analysis found that jurisdiction generally has a greater effect on approval time than line of business. The contrast at the extremes is almost difficult to process: a rate change that clears in under a day in Wisconsin takes a median 252 days in California for Commercial Property, and 246 days for Personal Auto.
That is not a rounding difference. That is the difference between a carrier updating its prices in January and updating them the following October.
California and New York rank among the three slowest jurisdictions across all three lines studied. Maryland, with a median of 210 days, also ranked among the three slowest for both Personal Auto and Commercial Property. New Jersey appeared among the slowest for Homeowners.
On the fast end, South Dakota, Alabama, New Mexico, and Arkansas were among the fastest jurisdictions. Wisconsin was the fastest in every single line.
If you live in a slow-approval state, the SMQI pattern is consistent: quoted premiums tend to reflect pricing that lags actual market conditions, then correct sharply when a large rate request finally clears. Drivers in New York or California are especially exposed to this dynamic.
What Regulators Are Actually Objecting To, and Why It Keeps Repeating
The most common objection themes differ meaningfully by line, and understanding them explains why the same delays recur year after year.
For Personal Auto, regulators in more than 20 states most commonly objected around Generalized Linear Model (GLM) and rating-factor construction support. Specifically, regulators asked carriers to explain variable selection, validation, segmentation methodology, and the construction of new rating factors. These are not obscure technical questions, they are foundational to any modern pricing model.
For Commercial Property, the leading theme in 16 states was Insurance Services Office (ISO) and American Association of Insurance Services (AAIS) Loss Cost Multiplier adoption and supporting documentation. The report calls this the most concentrated single regulatory ask of any line.
Homeowners requirements were more state-specific. Catastrophe-exposed states including Florida, South Carolina, and Hawaii focused on hurricane and wildfire model documentation. Consumer-protection states such as Georgia, Kansas, and New York examined individual policyholder rate caps.
"Filing quality and preparation can make a measurable difference. Knowing what regulators are likely to ask for before filing, and answering those questions in the original submission, can reduce avoidable follow-up and bring products to market weeks or months sooner."
That quote from Rehor points to the structural irony buried in this data. The regulatory process is designed to protect consumers, but when it generates 35,000 objection letters in a year on largely predictable grounds, the friction it creates ultimately flows back to policyholders through higher premiums and reduced market options.
The E&S Market Escape Valve: A Structural Side Effect of Slow Approvals
When the admitted market becomes too slow or uncertain, carriers do not simply absorb the friction. They route around it.
ZestyAI's report identifies a direct structural consequence of prolonged insurance rate filing delays: the harder it becomes to clear admitted rate filings, particularly in catastrophe-exposed personal lines markets, the more carriers shift volume to the Excess and Surplus (E&S) market.
The E&S market is not subject to Department of Insurance rate review. Carriers can price risk there without waiting for regulatory approval. That flexibility comes with a trade-off: E&S policies typically offer less consumer protection and can be harder to obtain or compare.
The scale of this shift is significant. The E&S market has set record share in each of the past three years.
That is not a coincidence. It is a structural response to a regulatory environment where nearly half of admitted filings draw a formal objection and where some states take the better part of a year to approve a rate change. When the cost of staying in the admitted market rises, carriers recalibrate. Consumers, particularly those in high-risk or catastrophe-exposed areas, end up with fewer admitted-market options and more limited protections.
What this means for you
If your premium jumped at renewal, a backed-up regulatory pipeline may be part of the reason. Compare quotes across multiple carriers before accepting a renewal offer, since pricing across admitted and E&S market options can vary widely in slow-approval states. Drivers in California, New York, and Maryland should pay particular attention to whether their current carrier is repricing aggressively after a long approval delay.

FAQ
Why do insurance rate filing delays affect my premium?
When a carrier's rate filing is held up by regulator objections, its pricing falls out of step with actual loss trends. When the filing finally clears, carriers often request a larger increase than they would have needed if approved on the original timeline. That compounding effect lands on policyholders at renewal.
Which states have the slowest rate filing approvals?
According to ZestyAI's Approval Velocity 2026 report, California and New York rank among the three slowest jurisdictions across all three lines analyzed. Maryland also ranked among the slowest for Personal Auto and Commercial Property, with a median approval time of 210 days. Wisconsin was the fastest in every line, clearing filings in under a day.
What is the E&S market and should I worry about it?
The Excess and Surplus (E&S) market allows carriers to write policies without filing rates for Department of Insurance approval. It has set record market share for three consecutive years, largely because slow admitted-market approvals push carriers toward it. E&S policies generally carry fewer consumer protections, so if you are being quoted E&S coverage, it is worth comparing it carefully against any available admitted-market options.
What types of rate filings get objected to most often?
Homeowners filings had the highest objection rate at 53.2%, followed closely by Personal Auto at 50.7%. Commercial Property was less contested at 34.3%. The most common objections centered on rating model documentation for Personal Auto, loss cost multiplier support for Commercial Property, and hurricane or wildfire model documentation for homeowners in catastrophe-exposed states.
Can carriers do anything to speed up rate approvals?
Yes, according to ZestyAI's research. Bryan Rehor noted that carriers which anticipate common regulator questions and submit the right supporting evidence from the outset can avoid objections entirely, eliminating the weeks or months those objections add. The report found that many objections recur from filing to filing on the same predictable grounds.
