Every fact below is quoted from the regulation or statute it cites. Where the primary sources do not settle a point, it is marked and left open rather than filled in — which is itself worth knowing before you argue it.

What is not yet confirmed here

The audit leaves what the insurer must show you and sales tax out of the headline range rather than guessing.

When a car counts as a total loss

Threshold 80%, but only for newer vehicles: a vehicle damaged within six years of its manufacturer's model year designation is a salvage vehicle where the total cost of repairs to rebuild it to its pre-damage condition for legal road operation exceeds 80 percent of its fair market value immediately before the damage. Vehicles older than that fall outside the definition.
“Was damaged during a year that is no more than six years after the manufacturer's model year designation for such vehicle to the extent that the total cost of repairs to rebuild or reconstruct the vehicle to its condition immediately before it was damaged for legal operation on the roads or highways exceeds eighty percent of the fair market value of the vehicle immediately preceding the time it was damaged”

The six-year limit is the part usually left out when Missouri is described as an '80 percent state'. For an older car the salvage definition does not bite at all, so the 80 percent figure is not a general Missouri total-loss threshold. This is a TITLING definition; Missouri's insurance regulation sets no threshold compelling an insurer to declare a total loss, so the decision remains the insurer's under the policy.

How the settlement must be valued

Missouri prescribes no total-loss valuation methodology. The one settlement constraint is a floor: the insurer may not use as the basis for a cash settlement an amount less than it would pay if repairs were made — except in total loss situations, or where the insured agrees.
“The insurer shall not use as a basis for cash settlement with a first-party claimant an amount which is less than the amount which the insurer would pay if repairs were made, other than in total loss situations, unless the amount is agreed to by the insured.”

Read the exception carefully, because it cuts against the claimant: the repair-cost floor expressly does NOT apply in total loss situations. So the provision that looks protective on first reading is the one that leaves a Missouri total loss without a methodology. The absence is the verified finding — 20 CSR 100-1.050 was read for a comparable-vehicle method, a market area and a fee rule and has none of them.

How comparables must be chosen

None. Missouri sets no minimum number of comparable vehicles, no distance or market-area limit, no recency window and no mileage tolerance.
“When the amount claimed is reduced because of betterment or depreciation, all information for the reduction shall be contained in the claim file. These reductions shall be itemized and appropriate in amount.”

The quoted provision, 20 CSR 100-1.050(2)(E), is the nearest thing Missouri has to a comparables constraint and it is the practical lever here: a betterment or depreciation reduction must be itemized, appropriate in amount, and fully documented in the claim file. Missouri's regulator has publicly cautioned that relying on valuation software alone does not discharge an insurer's duty under § 375.1007, as that guidance was not retrieved.

What the insurer must show you

partly verified
No rule requiring delivery of the valuation or an itemized explanation of the total-loss figure. What is required is that the information behind any betterment or depreciation reduction be contained in the claim file and itemized — a record-keeping duty, not a disclosure duty.
“all information for the reduction shall be contained in the claim file. These reductions shall be itemized and appropriate in amount.”

Recorded as an absence after reading the section for a delivery duty. The material therefore exists in the file by regulation but is not owed to you automatically — so ask for it in writing and date the request, relying on the prompt-fair-and-equitable duty in § 375.1007 rather than on a valuation-disclosure rule, because Missouri has none.

Sales tax

partly verified
No rule requires the insurer to include sales tax, but Missouri gives most of it back a different way: § 144.027 credits the insurance proceeds plus the deductible against the sales tax on a replacement bought within 180 days of the insurer's payment.
“the director shall permit the amount of the insurance proceeds plus any owner's deductible obligation, as certified by the insurance company, to be a credit against the purchase price of another motor vehicle”

Two facts pull in opposite directions here. No Missouri statute or regulation makes the insurer pay sales tax; the Revised Statutes were searched and the only matches were the salvage-title statute and the tax code. But § 144.027 means a Missouri owner who replaces the car within 180 days of the insurance payment owes sales tax only on the amount above the proceeds plus deductible, so the insurer will say the tax is not a loss at all. The reply is that the credit runs only to a replacement bought in time, and an owner who cannot replace within 180 days, or replaces for more, still bears it. Ask the insurer for the certified proceeds statement the statute requires.

Title and registration fees

confirmed: no rule
No rule located. Nothing in the settlement regulation or the wider code requires an insurer to include title, registration or transfer fees in a total-loss settlement.

The settlement regulation is silent on fees, and the Revised Statutes of Missouri was searched for a total-loss fee requirement; the only matches were the salvage-title statute (§ 301.213) and the tax code's replacement credit (§ 144.027). Some policy forms include these fees as a matter of contract, which is a policy question rather than a state requirement.

Appraisal clause

confirmed: no rule
No state rule located. Missouri's improper claims settlement practices regulation contains no appraisal procedure for a first-party auto valuation dispute; where an appraisal provision applies it is a term of the policy.

20 CSR 100-1.050 was retrieved and read and contains no mention of appraisal or an umpire. The remainder of 20 CSR 100 chapter 1 and Mo. Rev. Stat. ch. 375 were not retrieved section by section.

Claim-handling deadlines

The insurer must advise a first-party claimant of acceptance or denial within 15 working days after the submission of all forms necessary to establish the nature and extent of the claim.
“Within fifteen (15) working days after the submission of all forms necessary to establish the nature and extent of any claim, the first-party claimant shall be advised of the acceptance or denial.”

The clock runs in WORKING days, and — importantly — it starts only once ALL necessary forms have been submitted, which is a start point the insurer has considerable influence over. Pin down in writing the date the last requested item was sent. No acknowledgement clock or payment clock was located in this section, and the wider chapter 20 CSR 100-1 was not read section by section, so those are recorded as absent from this rule rather than absent from Missouri law.

Unfair claims practices law

Mo. Rev. Stat. § 375.1007 (improper claims practices), implemented by 20 CSR 100-1 — the standards for prompt, fair and equitable settlement of claims. The regulation states that it effectuates and aids in the interpretation of § 375.1007(3) and (4).
“Within fifteen (15) working days after the submission of all forms necessary to establish the nature and extent of any claim, the first-party claimant shall be advised of the acceptance or denial.”

The quote is from the regulation; § 375.1007 itself was not read directly, so the statutory citation is recorded without a quote. The regulation's own framing is that it interprets § 375.1007(3) and (4), which is why an argument in Missouri is usually pitched at the statutory duty of prompt, fair and equitable settlement with the regulation supplying the specifics.

Time limit to sue your own insurer

10 years
“An action upon any writing, whether sealed or unsealed, for”

TEN years on an action upon a writing for the payment of money — the longest period in the ledger alongside Illinois, and more than three times Maryland's or North Carolina's. The quoted fragment is the opening of subdivision (1) as retrieved. Check the policy for a shorter suit-limitation clause: a ten-year statutory period is exactly the situation in which a contractual clause makes the most difference.

Where to file a complaint

“The Division provides consumer information and investigates consumer complaints against insurance companies and producers for most types of insurance.”

The Division forwards the complaint to the insurer and requires a response, then reviews it for compliance with Missouri insurance law. It states it cannot establish the value of a claim, so the packet should lead with the specific rule or policy term at issue.

Open questions on this row (4)

These are the things we could not settle from primary sources. They are published rather than hidden, because a reader arguing this rule should know where it thins out.

  • Not yet read: the remainder of 20 CSR 100 chapter 1 for an acknowledgement clock and a payment clock. 20 CSR 100-1.050 supplies only the 15-working-day decision rule, and it would be wrong to conclude from that alone that Missouri has no other deadlines.
  • Not yet read at the source: Mo. Rev. Stat. § 375.1007 to capture a verbatim quote for the statute the regulation interprets, in particular subsections (3) and (4).
  • Not yet read at the source: the Missouri DCI guidance reported to warn insurers that valuation software alone does not discharge the duty under § 375.1007. If it exists as a bulletin, it is directly on point for a software-generated valuation and belongs in “how comparables must be chosen”.
  • Confirm whether Missouri enforces contractual suit-limitation clauses shorter than the ten years in § 516.110(1).
