Mississippi Car Insurance Claim Laws

How long insurers have to handle your car insurance claim in Mississippi, when a car counts as a total loss, and what to do if the insurer falls behind.

Last reviewed October 24, 2026 by Ali Ahmad, MyAutoTriage editor.

Short answer

Mississippi law sets no fixed number of days for an insurer to acknowledge, decide or pay a car insurance claim; it must still act promptly and in good faith. Total loss rule: the insurer decides when repairs are uneconomical; state law sets no fixed percentage. Deadline to file an injury lawsuit: 3 years.

Claim-handling deadlines in Mississippi

Mississippi has no statute or regulation setting auto claim deadlines; claims must still be handled promptly and in good faith.

No Mississippi statute or regulation sets auto claim deadlines.

The decision clock usually starts once the insurer has the proof of loss it asked for, not on the day of the accident. Ask the adjuster in writing what they still need, and keep a dated log of everything you send.

When a car is totaled in Mississippi

The insurer decides when repairs are uneconomical; state law sets no fixed percentage.

In practice most insurers apply the total loss formula: a car worth $15,000 with $3,000 of salvage value is usually totaled once repairs reach about $12,000. Ask the adjuster which test they used and for the valuation report.

Rule: Miss. Code Ann. § 63-21-1 et seq.; Miss. Admin. Code tit. 35, pt. VII, subpt. 6, ch. 5.

If the insurer misses a deadline or lowballs you

Send a short written follow-up that names the deadline and asks for a decision by a specific date.
If the offer is low, answer with evidence: repair estimates, comparable cars for sale, receipts.

If you have to sue the other driver in Mississippi

Most claims settle without a lawsuit, but these rules decide how much leverage you have when you claim against the at-fault driver's insurer.

If you were partly at fault	Pure comparative fault
Deadline to sue for injuries	3 years
Deadline to sue for car damage	3 years

You can recover from the other driver even if you were mostly at fault, minus your share of the blame: 30% at fault means 70% of your damages.

The lawsuit deadline (statute of limitations) usually runs from the accident date, and an open insurance claim does not pause it.

Rules: Miss. Code § 11-7-15; Miss. Code § 15-1-49.

Sales tax and fees on a total loss in Mississippi

Insurers must pay sales tax, title and license fees unless the policy clearly excludes them; the Department applies this to third-party claims. Rule: Mississippi Bulletin 2007-4.

From the at-fault driver's insurer: Yes, if you can prove it. Thomas v. Global Boat Builders, 482 So.2d 1112 (Miss. 1986), with proper proof.
From your own insurer: Not settled; depends on your policy. Older rulings allowed it (Potomac Ins. Co. v. Wilkinson, 57 So.2d 158 (Miss. 1952)); modern policy wording untested.

Alabama: 75% of value; decision within 30 calendar days after proof of loss
Tennessee: 75% of value; decision within 60 days after proof of loss
