What state rules require insurers to do in a total loss valuation

Most states regulate how an insurer values a totaled car, but the rules govern the method and the paperwork, not the final number. In states that follow the NAIC model, the insurer must base a cash settlement on comparable vehicles in your local market, include taxes and transfer fees, explain every deduction in dollars, and keep the documentation in the claim file. A low offer is not automatically a violation. An offer built on the wrong cars, with an unexplained deduction or missing fees, often is.

The detail varies a great deal. A few states, such as California and Washington, have long, specific total loss regulations. Others lean on a general fair-claims-practices act and a consumer guide. This article walks through the model rule that most states started from, compares several states' versions, explains where dealer location and condition adjustments fit, lists what you can demand in writing, and shows where to complain when a rule is broken.

Where the rules come from

The NAIC, the association of state insurance regulators, publishes two model documents on claims practices: an Unfair Property/Casualty Claims Settlement Practices Model Act and a model regulation that fills in the detail. Models are templates. States decide whether to adopt them, in whole or in part, and many changed the wording. The model regulation (Model 902), in the version posted by the NAIC with a 1997 date, has a section on prompt, fair and equitable settlements that applies to automobile insurance. A state's version may be a regulation, a statute or a bulletin, and any of them can have been amended since.

Two points about how these rules work:

• They set conduct standards for insurers, enforced by regulators. The NAIC model act itself creates no private right to sue an insurer for violating it. Whether a violation supports a lawsuit depends on the state's own law, which is a matter for a licensed attorney.
• Many of them apply to the policyholder's own claim. The model's total loss section is written for "first party automobile total losses." Some states, California among them, extend the standards to third-party claimants. If another driver's insurer is valuing your car, see when someone else totals your car: first-party vs third-party routes.

What the NAIC model says

The model's total loss section is the base for most state rules. In plain terms, when a policy pays a total loss on an actual cash value basis, the insurer uses one of these approaches:

1. A replacement vehicle. The insurer may offer a comparable car: same manufacturer, same or newer model year, similar body style, options and mileage, in as good or better condition, available for inspection at a licensed dealer within a reasonable distance of your home. It pays all taxes, license fees and transfer fees, with no cost to you beyond the deductible, and must document the offer.
2. A cash settlement based on the cost of a comparable car, less the deductible, including all applicable taxes, license fees and other fees incident to transferring ownership. That cost may come from: - two or more comparable cars in the local market area available (or available within the last 90 days); - if none are local, two or more in nearby areas, including the closest major metropolitan areas; - quotations from two or more licensed local dealers; or - a source of statistically valid fair market values, which must give primary consideration to the local market, produce values for at least 85 percent of makes and models for the last 15 model years, taking major options into account, and use current data from the area where the car was garaged.
3. A right of recourse. If you tell the insurer within 35 days of receiving the payment that you cannot buy a comparable car for the market value, the insurer must reopen the file. It may find a comparable car through a licensed dealer, pay you the difference or buy the car for you, offer a replacement, or settle through the policy's appraisal clause. It need not act if it gave you, at settlement, written notice of a specific comparable car, with its VIN, that you could have bought for the settlement value.

The model adds a rule for any settlement that departs from these methods: the departure must be supported by documentation of the car's condition, and every deduction, including salvage, must be measurable, discernible, itemized and specific as to dollar amount. The basis must be fully explained to you.

Related model provisions

• Insurers must respond within 15 days to claim communications that call for an answer.
• A denial of a first-party claim must cite the policy provision relied on and be in writing.
• If a claim is rejected and you object, the insurer must tell you in writing that you may have the matter reviewed by the state insurance department.
• Where liability and damages are reasonably clear, the insurer may not recommend that a third-party claimant use their own policy to avoid paying.

State deadlines for each of these differ; see unfair claims practices acts: the deadlines insurers must meet.

How states changed the model

The table compares several states' rules as they read in 2026. It is a guide to the kinds of differences, not a substitute for your state's current text.

A few of those differences deserve a closer look.

California

California's regulation, 10 CCR 2695.8, requires that a comparable car be like kind and quality, made by the same manufacturer, of the same or newer model year, and available for retail purchase by the general public in the local market within 90 days of the final offer. The insurer must identify comparables by VIN, stock number or plate and give the seller's contact details, and the cost must be fully itemized and explained in writing when the offer is made. Adjustments must be "discernible, measurable, itemized, and specified." A deduction for the car's condition is allowed only if its documented condition is below average for its year, make and model. The settlement includes all taxes and one-time transfer fees, plus license and annual fees prorated for the rest of the registration period.

Washington

Washington's total loss rules (WAC 284-30-391 and 284-30-392) were amended in a rule filed in August 2026 and effective October 18, 2026. As published, they cap the search area at 150 miles, expand in 25-mile steps, require comparable-vehicle lists of up to 30 entries from a computerized source, and require insurers to base every offer on itemized, verifiable dollar amounts for cars currently available or available within 90 days of the loss. Deductions for condition require supporting photographs and documentation. The insurer must provide a true and accurate copy of its valuation report if asked, and the report must list each comparable's source, date, seller contact or VIN, asking price, sold price if available and location. If you keep the car, the insurer must on request give the name of a salvage buyer who will pay the amount deducted, and the offer must stay open for 30 days. If you have rental coverage, the insurer may not cut it off before the earlier of seven calendar days after payment is sent or the rental coverage running out.

Florida

Florida's section 626.9743 is shorter. It lets an insurer settle on the cost of two or more comparable cars in the local market in the preceding 90 days, on retail cost from a generally recognized used-vehicle source (an electronic database, with the valuation documents provided on request, or a public guidebook that the insurer names on request), or on two dealer quotes. Deductions for betterment or depreciation must be itemized and explained in writing on request. The statute says sales tax is part of the cost only if it is applicable, and allows the insurer to defer payment of sales tax until the obligation has actually been incurred, which is a significant difference from states that pay it up front.

New York

New York's 11 NYCRR 216.7 takes a different approach, based on published valuation manuals. As the regulation is worded, a cash offer must be at least the average of retail values for a substantially similar vehicle from two approved manuals, with an allowance for documented dealer preparation charges up to $100, or a quote for a substantially similar car from a qualified dealer within 25 miles that stays available to you for three calendar days, or a value from an approved database that meets minimum criteria. The insurer must give you a detailed copy of its calculation no later than the date of payment. For a car purchased in the prior 180 days, the offer may be limited to the purchase price plus documented improvements, except for private-sale and gift acquisitions. Valuation sources change names over the years, so ask the insurer which approved source it used.

Texas and states without a long regulation

Not every state publishes a detailed valuation rule. The Texas Department of Insurance's consumer page on totaled cars, last updated in July 2026, tells owners they can ask the insurer what source it used to value the car, negotiate using local sales prices and dealer quotes, and document special features. In states with less specific rules, the policy's wording, the state's general fair-claims practices act and the appraisal clause do the work.

Dealer location and condition adjustments

Two choices inside a valuation move the number more than most others.

Where the comparables are. The rules speak of the "local market area," and they differ on how far an insurer can reach. A comparable 140 miles away is a different car, in practice, from one 8 miles away, because prices and supply vary by region. Washington's 150-mile cap and New York's 25-mile dealer quote are examples of defined limits, while the NAIC model and California rely on the local market and on an escalation to nearby metro areas. The rules also lean toward retail prices, the price a buyer would pay at a dealer, because that is what it costs you to replace the car. The rules do not generally require private-party prices to be used, nor forbid them.

What the insurer subtracts. Condition adjustments compare your car to the comparables. California allows a condition deduction only if the car's documented condition is below average, and requires that every adjustment be measurable and itemized. Washington requires photographs and documentation behind a condition deduction. These rules let you ask for the evidence: the photographs, the inspection notes, the dollar amount of each line. condition adjustments: why a totaled car is valued below its price looks at how those adjustments are built, and how to read a total loss valuation report line by line walks line by line through a report.

A separate fight is about the "negotiation adjustment," a percentage some valuation systems subtract from dealers' asking prices to reflect the usual haggle. Federal appeals courts have turned down class certification in suits over that practice, including the Fifth Circuit in 2023, the Third, Seventh, Fourth and Ninth Circuits in 2025 and the Sixth Circuit, en banc, in April 2026. Those rulings concern whether the cases can proceed as class actions, not whether the deduction is allowed in your claim. If your valuation contains such a line, ask the insurer to explain it in dollars and to show the dealer data behind it. More on lawsuits of this kind is in class actions against car insurers.

A worked audit with made-up numbers

Say your 2020 crossover, EX trim, 48,000 miles, in good condition, was totaled. The insurer's report lists three comparables. These numbers are hypothetical and are not market data.

The insurer averages the three adjusted values to $21,837, subtracts a $600 condition deduction labeled "wear" with no photographs, and offers $21,237 with no line for sales tax or fees.

Here is what a careful reader notices:

1. Comparable C is a 2019. Under the model's wording, and under California's, a comparable must be the same or newer model year. An older car adjusted upward is exactly what the language is meant to prevent. Whether your state's rule says the same is worth checking.
2. Comparable B is a lower trim. It may be acceptable if the adjustment is itemized and supported, but ask what data supports $1,300.
3. Comparable C is 140 miles away. That may be within a state's cap but is not "local," and should have prompted a question about closer cars.
4. The $600 condition deduction is unsupported. In states that require documentation, that line is a problem on its face.
5. There is no line for tax and fees. In most states following the model, they belong in the settlement.

Drop C, and the average of A and B is $22,105, which is $268 higher. Remove the unsupported $600. Add, at an assumed 6 percent sales tax, $1,326 and, say, $150 in transfer fees. The corrected figure is $23,581, about $2,344 above the offer. Your own state's tax and fee rules will differ, but the structure of the audit does not. The total loss payout estimator can help you build the corrected number.

What you can ask for, in writing

Use this as a checklist. Which items an insurer must supply depends on the state.

1. The complete valuation report, with each comparable's VIN or stock number, seller, location, asking and sold prices, and date.
2. The source and date of every database used, and any weighting applied.
3. An itemized list of adjustments for mileage, options and trim, with dollar amounts.
4. For any condition deduction, the inspection notes and photographs.
5. A statement of what taxes, title, registration and other fees are included, or an explanation of why sales tax is not.
6. The name and policy provision relied on for any other deduction, such as a prior unrepaired damage.
7. The deadline for requesting reopening or invoking appraisal.

If the insurer will not respond, the Washington insurance commissioner's office points out that the valuation report may not be provided unless you ask for it, which is a reason to ask early. Your own comparables are the best counter: three or four dated listings with VINs, plus maintenance records, and any special equipment. The negotiation steps are in how to negotiate a total loss settlement.

Where to go when a rule is broken

Start with the adjuster and the supervisor, in writing, citing the rule you think was missed. If that fails:

1. File a complaint with the state insurance department. Each state has a portal or form, and the guide to how to file a complaint against a car insurance company explains the process. Examples: the California Department of Insurance takes requests for assistance by phone (800-927-4357) or online; the Washington Office of the Insurance Commissioner has a Consumer Advocacy line (800-562-6900); the Texas Department of Insurance lists 800-252-3439. The insurer must generally respond to the department. What happens next is covered in after you file a department of insurance complaint: what to expect.
2. Understand what the department can and cannot do. Washington's commissioner says it cannot decide the amount you should be paid, but it can review whether the company followed the law and the policy. A regulator enforces conduct rules; it does not appraise cars.
3. Use the appraisal clause for a value dispute. Most policies let either side demand appraisal, in which each appoints an appraiser and the two choose an umpire. See the appraisal clause: settling a dispute over value. Washington's rule requires insurers to tell their appraisers to apply the state's total loss standards.
4. Try mediation if your state offers it. California runs an Automobile Claims Mediation Program for physical damage disputes, including the value of a total loss, but only after the department's complaint process, and generally where the claim exceeds $7,500 and the amount in dispute exceeds $2,000. It does not cover third-party claims. See arbitration and mediation in auto insurance disputes.
5. Consult a licensed attorney about claims for bad faith, statutory penalties or private suits. Whether a regulation violation supports a lawsuit is a question of state law.

Common questions

Does a low offer mean the insurer broke a rule?

Not by itself. The rules set how the number is built and documented. If the method is allowed and the documentation holds up, an offer you think is low is a negotiation, an appraisal or a mediation matter, not a regulatory violation.

Do these rules apply if the other driver's insurer is paying?

Sometimes. The NAIC model's valuation section is written for first-party claims. California says its provisions apply to third-party total loss claims without changing existing law on what the insurer owes. In other states, a third-party claim is measured by tort law's idea of the car's value just before the loss. Ask the adjuster which standard it is using.

Can I get the valuation report?

In Washington, the insurer must provide a true copy if asked. In Florida, the pertinent database documents must be provided on request. Elsewhere, ask, and if the insurer says no, ask your state insurance department whether it must provide it.

What if my state has no total loss regulation?

Then the general claims practices law, the policy language and the appraisal clause set the terms. The insurer must still act in good faith and explain its position. A call to your state insurance department can tell you what applies.

Do the rules cover leases?

The valuation method is generally the same, but the leasing company is the owner and is paid first. See totaled leased car: how the lessor, gap and payoff interact.

Key takeaways

• State rules on total loss valuation regulate method and documentation: comparable cars, taxes and fees, itemized deductions and proof, not the final dollar figure.
• Most states started from the NAIC model, but California, Washington, Florida and New York each differ on search area, data windows, proof and the treatment of sales tax.
• Condition deductions and cars of a different year or trim are the places valuations most often depart from the rules; ask for the photographs and the itemization.
• You can usually ask for the valuation report, a tax and fee breakdown and the comparables in writing, and the 35-day reopening right exists in many states.
• A state insurance department enforces conduct rules and takes complaints; value disputes are resolved through negotiation, appraisal, mediation or an attorney.
