Frequently Asked Questions

Personal property tax is a tax based upon the value of taxable personal property.  Taxable personal property consist of motor vehicles, trailers, mobile homes, watercraft, boat motors, aircraft, livestock, farm machinery and equipment, agricultural crops and any other personal property not exempted by law.  The Market Value of an item is established by the County Assessor using a standard rate book provided by the Missouri State Tax Commission.  The Assessed Value is a percentage of the Market Value.  The Assessed Value of an item multiplied by the tax rate (levy) for your district determines the amount of personal property tax you pay.

All taxable personal property shall be assessed in the county in which the owner resides the first day of January each year. 

Percentage of Market Value That Determines Assessed Value

Each year, you are required to fill out an assessment form with the County Assessor’s Office listing the taxable personal property you own January 1st of the tax year.  Generally, these forms are mailed out to the taxpayer in January and are due back to the Assessor no later than March 1st.  If you do not get a form to fill out in the mail, please contact the Assessor’s office at 636-797-5343.  Substantial late filing fees are assigned by the Assessor if you do not return your form by the deadline.

If you have recently moved into the county, it is your responsibility to contact the Assessor’s office to obtain an assessment form and be added to the county tax rolls.  It is also your responsibility to keep us informed of your current address. 

Tax bills will appear on our website in November and will be mailed late November.  If you have not received a bill by December 1st please contact the Collector’s office at 636-797-5406 to check the status of your tax record and verify the mailing address.  Personal Property Tax is due on December 31st of the tax year and become delinquent on January 1st of the following year.

Personal property is based on ownership as of January 1, each year. If you purchase a vehicle January 2nd you do not pay on it until the following year, but if it’s owned on the first day you pay for the full year regardless of when it is sold. Unfortunately, the law has no provisions for pro-rating taxes due.

Payment should be made payable to Michelle Worth, Collector of Jefferson County, and may be paid in the form of cash, cashier’s check, money order, personal check, any major credit card, debit card (2.5% with a minimum of $1.95 convenience fee) or by E-check ($4.95 convenience fee). You may pay at our office located at 729 Maple Street, Hillsboro, MO 63050, online at Jefferson County Property Taxes or by Interactive Voice Response by calling 1-877-289-0099 (if paying by IVR you will need to know your bill number and an additional fee of $1.95 will be charged).

As a taxpayer, please be aware that interest and penalty start accruing January 1^st of each year. If you do not receive your bill by the end of November, it is your responsibility to contact the Collector’s Office to find out why. The Collector’s Office does not have the authority to remove or reduce interest and penalties per state statute Number 139.100.3. (The Attorney General for the State of Missouri has issued a legal opinion Number 80-2004 that the Collector of Revenue does not have the authority to waive penalties or interest on delinquent real or personal property taxes.)

There is a $1 fee for a duplicate copy or waiver. You may mail in your request, giving us your name and the year(s) that you need along with $1 for each copy needed. You may also come to the office and pick up a copy at the cashier window for $1 each.
