Vehicle Personal Property Tax in Missouri: Assessment and Receipts

The Missouri vehicle personal property tax is an annual county-level tax on cars, trucks, motorcycles, RVs, and trailers, assessed at 33⅓% of market value and multiplied by your local levy rate. If you owned the vehicle on January 1, you owe the full year’s tax to the county where you lived on that date, you file an assessment list by March 1, and you pay the bill by December 31. Keep the receipt. You cannot renew your license plates without it.

Who Owes the Tax

Ownership on January 1 is what triggers the tax. Sell the car in February, total it in March, move out of state in June: you still owe the full year to the Missouri county where you lived on January 1.¹ The obligation stays with you, not the vehicle’s next owner.

The mirror image applies to new residents. If you moved into Missouri after January 1, you typically owe nothing for that year, and your first bill comes the following year. You will still need a document for registration in the meantime, which is covered below.

Filing the Assessment List

Every vehicle owner files a personal property assessment list with their county assessor between January 1 and March 1.¹ The form (often called Form 100) asks for the VIN, make, model, and year of each vehicle you own, plus purchase dates for anything you acquired during the prior year. Most assessors mail the form to you or post it online.

Confirm your mailing address while you are filing. If the assessor has an old address, you may never see the tax bill in November, and not receiving one does not excuse late payment.

The May 1 Grace Period

Miss March 1 and the assessor estimates your property from prior-year records and adds a late-filing penalty to your bill. The penalty scales with assessed value:²

$0–$1,000 assessed value: $15
$1,001–$2,000: $25
$2,001–$3,000: $35
$3,001–$4,000: $45
$4,001–$5,000: $55
$5,001–$6,000: $65
$6,001–$7,000: $75
$7,001–$8,000: $85
$8,001–$9,000: $95
$9,001 and above: $105

Here is the part worth knowing: file before May 1 and the penalty does not apply, even though you technically missed March 1.² That two-month window is effectively a soft deadline. After May 1, the penalty is locked in.

How the Bill Is Calculated

Two steps: assessed value, then levy rate.

Assessed Value

Missouri assesses vehicles at 33⅓% of true market value.³ Market value comes from the trade-in figure in the October issue of a nationally recognized automotive pricing guide. State law names NADA, Kelley Blue Book, and Edmunds as acceptable sources, and the State Tax Commission chooses which one every assessor must use.⁴ The assessor cannot use a value above the average trade-in figure without physically inspecting your vehicle. Vehicles two years old or newer from the model year are the exception.

A vehicle with a $18,000 October trade-in value has an assessed value of $6,000.

The Under-$50,000 Assessment Cap

A rule effective January 1, 2025, keeps your assessment from climbing year over year. If the vehicle’s true market value is under $50,000 and it was properly assessed the prior year, the assessor cannot set this year’s assessed value higher than last year’s.⁴ For a new vehicle, the cap begins in your second year of ownership. If your bill jumped and your vehicle is under the threshold, point the assessor to this provision before doing anything more formal.

Local Levy Rate

Assessed value gets multiplied by the combined levy rate for your tax district. Levies are stated per $100 of assessed value and voted in by local voters, bundling together your school district, city or county, fire district, library, and other local entities. Two neighbors in different school districts can owe noticeably different amounts on the same vehicle.

Continuing the example: $6,000 assessed value at a combined levy of $6.50 per $100 is $390 in tax.

Paying the Bill

County collectors mail bills in November or early December, and payment is due December 31.⁵ Most counties take payment online, by mail, or in person at the courthouse. Credit card payments usually carry a 2–2.5% convenience fee; electronic checks are often free or a small flat fee.

Payments received or postmarked after December 31 are delinquent and accrue penalties and interest under state law.⁵ If you are mailing at the end of December, remember that the post office does not guarantee a same-day postmark for items dropped off late.

Why the Receipt Matters for Registration

Missouri ties personal property tax directly to vehicle registration. You cannot register a vehicle or renew plates without a paid personal property tax receipt for the previous tax year, or a certified statement from the county collector showing no taxes were due.⁶ The receipt has to show every year’s taxes paid, including any delinquent balances. For a two-year registration, you need proof of payment for each year in the period.⁷

If you did not own property on the previous January 1, ask your county assessor or collector for a statement of non-assessment. This works in place of a paid receipt at registration. New residents usually need a government-issued ID, proof of a current Missouri address, and their most recent out-of-state registration to get one.

Appealing Your Assessment

If you think the value is too high, Missouri has a three-step appeal process, and the first step is informal.

Informal hearing. Contact the assessor’s office between late April and early June. Most disputes end here. Bring evidence: a recent sale price, comparable listings, or documentation of damage or high mileage.
Board of Equalization. If the informal hearing does not settle it, appeal to the county Board of Equalization, which meets in July and August. Filing deadlines vary by county but are commonly the second Monday in July. Skipping this step forfeits your right to go further.⁸
State Tax Commission. If the board rules against you, appeal to the Missouri State Tax Commission by September 30, or within 30 days of the board’s decision, whichever is later. In certain charter counties and cities, the assessor bears the burden of proving the valuation does not exceed true market value.⁸

Leased Vehicles

If you lease, the leasing company owes the personal property tax, not you. The tax is still assessed in the county where the lessee lives, and the receipt is issued in the leasing company’s name.⁹ When you register the vehicle, the leasing company must give you an original paid receipt or a collector-certified copy. If your registration is coming due and you have not received one, contact the leasing company directly. You cannot obtain the receipt in your own name.

Active-Duty Military

Service members stationed in Missouri but domiciled in another state are not subject to Missouri personal property tax on their vehicles. Federal law under the Servicemembers Civil Relief Act treats a service member’s personal property as not located in the state where they are stationed for tax purposes.¹⁰ The Military Spouses Residency Relief Act extends the protection to a spouse whose domicile is also in another state.

The protection does not cover vehicles used in a trade or business, and it does not apply to service members who claim Missouri as their domicile. To register a vehicle without a tax receipt, a service member can present a leave and earnings statement showing active-duty status and out-of-state domicile.⁶

Exemptions Are Narrow

Few vehicle owners qualify for a full exemption. The relevant statutory categories include vehicles leased to the state, a county, or a qualifying religious, educational, or charitable organization and used exclusively for those purposes, and property belonging to veterans’ organizations with a congressional charter and 26 U.S.C. § 501(c)(19) status.¹¹

Missouri does not offer a general vehicle personal property tax exemption for disabled veterans or seniors. The state’s property tax credit program for 100% disabled veterans applies to real estate taxes and rent, not vehicles.

Deducting the Tax on Your Federal Return

Because Missouri’s vehicle tax is annual and based on value, it qualifies as a deductible personal property tax on your federal return. Claim it on Schedule A, line 5c. Only the value-based portion counts; any flat or weight-based fees on the same bill are not deductible. The deduction falls under the state and local tax cap, which for 2026 is $40,400 for most filers and $20,000 for married filing separately, and you have to itemize for it to matter.¹²
