What is personal property?
According to Missouri State Statute 137.075, "Persons owning or holding tangible personal property on the first day of January shall be liable for taxes."

I am active duty military. Do I have to pay personal property taxes?
Active duty military applicants whose home of record is NOT Missouri are eligible for a tax waiver. To obtain a tax waiver, you must present your current Leave and Earnings Statement (LES), which indicates Missouri is NOT your home of record.
How does the Assessor know what personal property I have?
If you have taxable personal property in Platte County, you are required to report it to the Platte County Assessor. This is done by using the Personal Property Assessment form sent out by the Assessor's Office at the beginning of each year. The form lists the personal property you reported the previous year. It is your responsibility to return the form to the Assessor's Office by March 1 with any corrections and a list of any new personal property you owned on January 1.
When do I have to file my personal property?
Personal Property Assessment forms are mailed out the first week of January and are due to the Assessor’s Office no later than March 1 to avoid late filing fees. For your convenience, you can file your assessment online at www.plattecountyassessor.net. Simply enter the PIN number located on the front of your form to get started.
What if I listed something incorrectly on my assessment?
The tax statement you receive in November will be incorrect. You will need to contact our office as soon as possible so we can make the appropriate changes as soon as possible.
What if I don't receive a personal property list in the mail?
If you do not receive an assessment form, please contact the Platte County Assessor's Office at (816) 858-3303 and a form will be provided to you.
When and how is personal property valued?
Personal property is assessed every year and is calculated using original cost and then applying depreciation tables. Taxpayers are required by Missouri law to file their personal property after January 1 and before March 1.
|Personal Property Type||% of Market Value|
|Grain||1/2 of 1%|
|Historic Aircraft & Vehicles||5%|
|Motor Vehicles||33 1/3%|
|All Other Personal Property||33 1/3%|
What if I disagree with the assessed value placed on my property?
1. Informal Hearing: If you feel the value of your personal property is incorrect, call the Platte County Assessor's office at 816-858-3310.
2. State Tax Commission: Under State Tax Commission rule 12 CSR 30-3.010(1)(B), if the assessment is an initial assessment or an increase over a previous assessment and the assessor failed to notify the taxpayer of the assessment in time to appeal to the board of equalization (BOE), then the taxpayer may file an appeal directly with the State Tax Commission no later than December 31st or within 30 days after the county mailed the tax statement, whichever date is later. Because STC notice to the collector may not arrive until after the taxpayer pays the taxes, the taxpayer should provide the collector a protest letter when paying the taxes.
Does the Assessor's Office set the levy rates?
No, the assessor only values property.
What is a tax waiver and who is eligible for one?
A tax waiver indicates you do not owe any personal property taxes for a specified tax year. (View Tax Waiver Eligibility)

Why am I being taxed on a vehicle I no longer own?
You are taxed based on vehicles owned on January 1 of the tax year. Even if you no longer own the vehicles, and now own different vehicles or don't own any vehicles, you still pay taxes based on what you owned on the first day of the year.
Do I claim a vehicle that is not running?
Yes. Any vehicle titled in your name must be claimed regardless of condition.
What do I need to license a car not listed on my tax receipt?
If you bought your car after January 1 of this year, use last year's receipt. Property taxes are not owed on the new vehicle unless you owned it on January 1. If you did own the vehicle on January 1 of the previous year and it is not listed or is incorrect on your receipt or statement, please contact the Assessor's Office.
Which year's tax receipts do I need when renewing 2-year license plates?
You will need your two previous year’s personal property tax receipts. If you were assessed in another Missouri county, you may need to contact that county for a previous year receipt. If you cannot locate your tax receipt for the appropriate year, please call the Platte County Collector’s Office at (816) 858-3356 or visit the Platte County Collector's website.
When will I get my personal property tax bill?

I just moved to Platte County. What do I have to do?

I just moved to another Missouri County. What do I have to do?
If you moved prior to January 1 of this year and your mail was forwarded, please update the Personal Property Assessment form with your new residence and the date you moved from Platte County. Sign and return the form to the Assessor's Office by March 1. If you moved after the 1st of January of this year, you are still responsible for the taxes on any personal property owned in Platte County on January 1. Under state law, there is no provision for prorating taxes for the partial year.
I am no longer a MIssouri resident. Do I still owe?
