City Resident? Follow the Property Tax Route Through St. Charles County
If you live in the City of St. Charles, your vehicle and other taxable personal property are handled through St. Charles County—not a separate City personal property tax office. The County Assessor determines what is taxable and its assessed value; the County Collector creates the bill, accepts payment and issues receipts.
This guide connects the entire process: January 1 ownership, the March 1 assessment filing, late penalties, tax calculation, fall billing, December payment, DMV receipt timing, tax waivers, leased vehicles, partial payments, corrections and valuation appeals.
Quick answer: St. Charles City residents use St. Charles County
For a tax bill, payment or receipt, use the St. Charles County Collector of Revenue. For a missing vehicle, wrong personal property record, assessment filing, value question or tax waiver, use the St. Charles County Assessor.

Personal property is assessed at 33⅓% of market value
Assessment is only the first half of the formula
St. Charles County uses Missouri’s statewide personal property assessment rate of 33⅓%. The assessed value is then divided by 100 and multiplied by the combined tax rate applying to your location.
Tax rates can include multiple jurisdictions such as school, fire, ambulance, library, city and other taxing entities.
County example
$100,000
$100,000 × .333333 = approximately $33,333.
Using the County’s example 6.5694 rate: approximately $2,189.58.
Partial payment and advance payment solve opposite problems
For taxpayers who have fallen behind and want to reduce the remaining balance and future late charges.
- Minimum payment: $20
- Available for personal property and real estate bills
- Receipt shows remaining balance
- Vehicle-registration receipt waits until full payment
For taxpayers current on prior years who want to start paying toward the current year’s future bill.
- Minimum payment: $20
- Prior years must be paid in full
- Current personal property assessment must already be filed
- Credit appears on the eventual annual bill
If there is no paid tax receipt, you may actually need a tax waiver
A Certificate of Personal Property Non-Assessment shows that St. Charles County records indicate no personal property tax was due for the specified person or tax year. It is commonly needed when titling or licensing a vehicle but there is no prior paid County tax receipt.
Prepare a properly assigned title, Missouri title/license application or qualifying bill of sale showing vehicle and transaction details.
Prepare the vehicle title or current out-of-state registration.
If you lived elsewhere on January 1 of the required tax year, obtain the non-assessment certificate from the appropriate former county.
Who does what?
Personal Property staff review the required information and documentation.
After Assessor verification, the Collector signs and issues the final Certificate of Non-Assessment.
Do not report a leased vehicle as if you own it
The leasing company may provide the paid personal property tax receipt. If it does not, a copy can be requested from the Collector.
Depending on the vehicle-registration situation, you may need a Certificate of Personal Property Non-Assessment.
For a leased-vehicle waiver request
Think the assessed value is wrong? Use the formal appeal ladder
County informal hearings generally run from late April through early June to discuss value or classification with Assessor staff.
The 2026 filing deadline was 5 p.m. on the second Monday in July. That deadline has now passed.
After the BOE, the County describes a further appeal to the Missouri State Tax Commission under applicable deadlines.
