How to Pay Personal Property Tax in Missouri
Where to Send Your Personal Property Tax Payment
Personal property tax in Missouri is collected by your county assessor's office, not the state. You pay the county where the property is located. The assessor's office sends you a bill, usually in the fall, and payment is due by December 31st of that year. If you do not receive a bill, contact your county assessor directly — they have your address on file and can tell you the amount owed.
You can pay in person at the assessor's office during business hours, by mail to the address printed on your bill, or online if your county offers it. Some counties accept payment at the collector's office instead of the assessor's office; your bill will specify which one. A few Missouri counties now accept credit or debit card payments online, though this varies by location.
If you move or your mailing address changes, notify your county assessor so future bills reach you. Unpaid personal property tax accrues interest and can result in a lien against the property, making it harder to sell or refinance.

What Personal Property Tax Covers in Missouri
Personal property tax applies to tangible items you own that are not real estate — vehicles, equipment, machinery, furniture, and inventory used in a business. If you own a car, motorcycle, or boat registered in Missouri, you owe personal property tax on it. Business owners pay tax on equipment, tools, and stock held for sale.
Household items like appliances and clothing are generally not taxed. The assessor's office determines the taxable value based on the item's age, condition, and market value. For vehicles, they use the manufacturer's list price and depreciation schedules. For business equipment, they may conduct a physical inspection or accept a written inventory from you.
How to Find Your County Assessor's Office
Search online for "[Your County Name] Missouri Assessor" to find the office website, phone number, and mailing address. Most county assessor websites list payment methods, office hours, and whether online payment is available. You can also call your county clerk's office if you cannot locate the assessor.
Keep your bill or a copy of it when you contact the assessor. Have your property description or account number ready so they can pull up your record quickly. If you have questions about the assessed value, the assessor's office can explain how it was calculated and what you can do if you believe it is incorrect.
Late Payments and Penalties
If your payment arrives after December 31st, Missouri law imposes a penalty. The exact penalty amount varies by county but typically ranges from a percentage of the tax owed to a flat fee. Interest also begins accruing on the unpaid balance, compounding monthly. The longer you wait, the more you owe.
If the debt goes unpaid for an extended period, the county may file a lien against the property. This lien appears on your title and can prevent you from selling or refinancing until it is satisfied. If you cannot pay by the deadline, contact your assessor's office to discuss a payment plan or hardship options — some counties offer them, though they are not may provide.
Disputing the Assessed Value
If you believe your personal property has been overvalued, you can file a formal objection with your county assessor. The process and deadline vary by county, but most require you to file within a set window after receiving your bill — often 30 to 60 days. Check your bill or the assessor's website for the exact deadline in your county.
Bring documentation to support your claim: recent purchase receipts, repair estimates, or a professional appraisal showing the item's actual value. The assessor will review your evidence and may adjust the assessment. If you disagree with their decision, some counties allow you to appeal to the county board of equalization or a local tax commission.
Payment Methods and Timing
| Payment Method | Timing | What You Need |
|---|---|---|
| Allow 7–10 days for delivery; postmark by December 31st | Check or money order; your bill or account number | |
| In Person | Same day; must arrive before office closes on December 31st | Cash, check, or card (if accepted); your bill |
| Online | Immediate; available in some counties only | Your account number; credit or debit card |
If you pay by mail, send your payment early enough that it arrives before the deadline. The postmark date matters — if your check is postmarked by December 31st but arrives in January, it may still be considered on time, depending on your county's rules. Call the assessor's office to confirm their policy.
Online payment is the fastest and safest option if your county offers it. You receive immediate confirmation and a receipt number. If you pay in person, ask for a receipt showing the date and amount paid. Keep this receipt for your records.
Frequently Asked Questions
What happens if I do not pay personal property tax?
Interest and penalties accumulate each month. After a set period of non-payment, the county can file a lien on the property, which damages your credit and prevents you from selling or refinancing. Eventually, the county may pursue collection through wage garnishment or bank levy.
Can I pay personal property tax online in Missouri?
Some Missouri counties offer online payment through their assessor's website, but not all. Check your bill or call your county assessor's office to see if this option is available in your county. If it is, you will typically need your account number and a credit or debit card.
Who pays personal property tax on a financed vehicle?
The registered owner pays personal property tax, even if the vehicle is financed. Your lender does not pay it for you. Make sure your mailing address is current with the assessor so you receive the bill on time.
Can I get an extension on my personal property tax payment?
Missouri law does not provide an automatic extension for personal property tax. However, some counties may work with you if you contact them before the deadline and explain your situation. Call your assessor's office to ask whether a payment plan or hardship deferral is available.
How do I know if my personal property is taxable?
Contact your county assessor's office with a description of the item. They can tell you whether it is subject to tax and, if so, what the assessed value is. Household items are generally exempt, but business equipment and vehicles almost always are taxable.
