The party responsible for the taxes should be stated in your rental agreement. If it is a ‘rent to own’ agreement, you may be responsible. Make sure to check your agreement or contact whomever you are renting from.
Unless we are informed otherwise by the park or the taxpayer, the person named on the title or the purchasing agreement for the mobile home will be responsible for the taxes.
More than likely, we did not receive your personal assessment list, but the mobile home was rendered to us by the park. When that happens, we do not assess the vehicles until the taxpayer either sends in their personal assessment list or comes in to one of our locations to be assessed.
Mobile homes are only considered real estate if they are permanently affixed to a permanent foundation. If that is the case, you need to make sure to contact Clay County.
Mobile homes are assessed from the October issue of the NADA book , and assessed at 19% per the State of Missouri.
Mobile homes are assessed similarly to vehicles in the fact that it is based on who owned the mobile home on January 1st, where the mobile home was located, year, and make of the mobile home.
Mobile homes differ from vehicles in the fact that they are claimed where they are located and not where the owner is located. Also, the total square footage is taken into consideration when figuring the assessed value.
Per Section 137.092, RsMo the mobile home parks are responsible for rendering the mobile homes and owners located within the park to the Assessor’s office every year. So, even if you don’t claim it on your personal list, it may still be added based on the report that we receive from your park.
The assessment of military personnel continues to be an area of confusion, judging from the number of calls we receive on this subject. The law in this area is controlled by the federal Soldiers and Sailors Relief Act of 1940. The United States Supreme Court has stated that military personnel shall not lose their residence or domicile in their home state solely because they are absent from the state in compliance with military or naval orders. However, military personnel stationed away from Missouri must still pay personal property taxes in Missouri assuming they retain Missouri as their home state of record.
The military personnel are treated as though they never left their home state and county. Consequently, assessors should treat the tangible personal property stationed in other states or countries the same as if the taxpayer is living in the county and the personal property is present in the state. The other side of the matter, is that personal property of any individuals residing in your county by means of military orders are not taxable in your jurisdiction, with the exception of business personal property located in Missouri and owned by non-resident military personnel.
The Attorney General issued an opinion [Burrell, Op. Att’y. Gen. No 95 (Feb 16, 1966)] concluding that non-resident military personnel stationed in Missouri may obtain a certificate of no tax due (a waiver) from the collector and license their cars in Missouri; however, if a military spouse is the sole owner, it should be taxed as any other resident. Verification of the home of record is easily ascertainable by looking at the bottom portion of the “Leave and Earnings Statement” (i.e., pay stub) which indicates the individual’s claimed home state of record.
Where Military Personal Property is Taxed:
| Type of Owner | Location of Property | Where Taxed |
| Non-MO Resident Military | In Missouri | Non taxable |
| MO Resident Military | In Missouri | In county of residence |
| MO Resident Military | Outside Missouri (voluntary reporting) | In county of residence |
| MO Resident Military | Outside Missouri (non-reporting) | In county of residence |
Aircraft are assessed based on year, make, model number, and hours flown the previous year. We use the spring issue of the Aircraft Blue Book per the State of Missouri.
An Aircraft is considered historic when it is 25 years or older and flown under 50 hours in a year.
Kit planes are always assessed at the historic aircraft percentage based on the purchase price of the kit, purchase amount for additional parts, and number of labor hours.
Aircraft will still need to be assessed even if they are in parts. They will be assessed at the historic percentage based on total purchase amount.
An Aircraft is eligible to be assessed by the State Tax Commission if it is used for commercial purposes and has a gross take-off weight of over 3,000lbs. Owners choosing to have their aircraft assessed by the State will need to inform Clay County. More information is available at the State Tax Commission web site.
You will need your two previous year’s 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 Collector’s office at (816) 407-3200 for additional information.
Yes. The date of purchase listed on the application for title is the date you actually owned it regardless of when you picked it up.
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 1st. If you did own the vehicle on January 1 of last year and it is not listed on your receipt, or is incorrect on you receipt or statement, please contact the Assessor’s office.

The Change of Value Notice displays previous market value and current market value by calendar year. Current and historical change of value notices are available online here.
School Districts, Fire Districts, Ambulance Districts, Road Districts, Water Districts, Hospital Districts, Library Districts, Junior College along with City and County Districts. Your property location determines which districts receive your tax dollars. You will receive a separate city tax bill.
A tax levy is a number determined by a taxing authority such as a school district used in calculating, from the assessed value, the amount owed to that taxing authority for that tax year. As government services and costs increase, levies and taxes have to be raised to pay for these services.
Tax levies and taxes increase due to increased costs of school and government services. The Assessor is tasked to value property at current market value as of January 1st. As the cost of schools and government increases, so do your taxes. An increase in your tax bill can be the result of an increase in your tax levy, an increase in your property assessment, a combination of tax levy & reassessment, or new construction on your property.
The assessed value of your property is used to determine your portion of real estate taxes paid to support local school and government services. It is important to you and to our office that your assessed valuation is accurate.
The amount of real estate taxes paid in Clay County is determined by local taxing authorities such as school, fire, library, hospital, and road districts, along with city and county taxing authorities. This is why it is important to be aware of any proposed changes in spending by your local schools or governments.
Market value is the appraised value of your property as January 1st. Assessed value is calculated by multiplying the property market value, based on classification, by the correct assessment ratio. Classifications: Agricultural – 12%, Residential – 19%, Commercial – 32%.
Foreclosure sales of real property are typically not considered a true arm’s length transaction, mainly for two reasons: 1) Seller motivation (do I have to sell to stop a foreclosure action or a bank owned property) when selling a foreclosure property is much different than a typical sale. 2) The physical condition of a foreclosure property is usually poor. Normally a foreclosure property will require extensive repairs to become salable. Foreclosure properties affect market value by forcing competing properties to adjust asking prices. Current sale data shows that real property not under duress to sell may have a longer marketing period, but sells for a much higher value than a distressed foreclosure sale.
Market value, true market value in money and appraised value have the same meaning under Missouri law. A simple definition of market value is the price the property would bring when offered for sale by a person who is willing but not obligated to sell and it is bought by a person who is willing to purchase it but who is not forced to do so.
The Assessor’s Office continually collects and researches sales and lease data, income and expense data, along with other market factors when appraising the current market value of real property. An important point to remember is that the Assessor Office does not create market value; it analyzes the transactions of buyers and sellers to help determine property values during the reassessment process. It is buyers and sellers that determine the levels of property value with arm’s length sales transactions in the market place. Collected sales data is used to determine your properties current market value.
Once appraised values have been calculated based on information gathered by appraisers, the values are analyzed to determine how accurate and equitable they are. The Assessor’s Office staff compares assessments to sales prices to determine ratios, which are then used to measure the level and uniformity of assessments. Sales ratio studies by neighborhood, type of property, and other criteria are performed regularly to assure uniformity of values.
The Assessor’s Office is tasked to ensure that the tax burden is distributed equitably among all property owners. To accomplish this, Missouri Revised Statutes – Chapter 137, is followed when assessing all real property.
Re-assessment is the process that helps to validate that real property is valued at current market value. All real property in Clay County is valued with uniform and consistent procedures following Missouri Revised Statutes – Chapter 137. Over time the value of property changes due to market conditions, location, condition of property, and other physical and economic factors. Some property values change more rapidly than others. Reassessment identifies changes in market value, along with property condition to determine current market value.
Missouri Revised Statute 137.115 requires that the Assessor reassess all real property every 2 years on January 1st, in the odd numbered year. This value is carried forward to the even numbered year except for new construction and property improvements.
You are liable for the complete tax amount based on the property you owned on January 1, even if you moved later that year. You pay your taxes in your county of residence on January 1 (of the current year, not of the coming up year). There is no provision in Missouri law for partial refunds on your tax bill. If you are leaving Clay County (or Missouri), please present your tax receipts when enrolling in your new place of residence.
If you move into Clay County from another county, you also need to fill out an Assessment List. Please see our New Resident page for more information.
Anytime you move into Clay County, within Clay County, or out of Clay County, you need to let Clay County know. Please only fill out this form for personal property (non-real estate) tax purposes.
You also need to notify the Assessor’s office of your old county of residence (if moving into Clay County) or your new county of residence (if moving out of Clay County).
By Missouri law, taxpayers owe taxes based on the property they owned on January 1 of each year. That means, that even if you moved out of county or even out of state , you still owe taxes if you were a resident on January 1. Please understand that you have an obligation to let us know if (and when) your place of residence has changed, so that your assessment forms and tax bills can be sent to you. You are, by state law, responsible for payment of your taxes, including applicable penalties and interest, even if you do not receive a tax bill. Penalties and interest may, by Missouri law, only be waived for personnel on active military duty.
When you get your assessment list in the mail, you will find that your address and property from the previous year are pre-printed on the form. If there are changes to your address, please make those changes in the spaces provided. Even if you have moved out of Clay County, and your mail was forwarded please mail the list back to the Assessor’s office informing us of this so that you may be removed from the tax rolls and avoid future mailings.
The property that is preprinted on the list is the property that was on file for you the preceding year. Any property that has been disposed of you will need to draw a line through and provide the date disposed of. Below the list of pre-printed items are sections for you to list property that was acquired during the previous year. Be sure to fill the form out completely. Do not re-list property that has been pre-printed for you. Should corrections need to be made to the pre-printed property lines item, make those corrections directly to them.
The assessment form must be accurately completed and returned to the Clay County Assessor’s office before March 1 in order to avoid a late filing penalty.
Generally, leased vehicles are claimed by the leasing company and you are not directly responsible for the taxes. However, there are exceptions so you may want to check with your leasing company before listing a leased vehicle.
If you have further questions, please contact the Assessor’s Office at (816) 407-3520 (personal property) or (816) 407-3470 (business personal property).

The tax responsibility goes to the owner of record on January 1. If property is owned jointly and the court order dissolving the marriage does not address tax liability, both parties are jointly responsible for taxes. Neither party can obtain a statement of no taxes due until the tax liability is satisfied. If you are separated and not legally divorced we can not split the bill once it is made. We can separate the account for the next year. If you are legally divorced you will need to provide copies of the final divorce decree showing who is responsible for each vehicle and you must have a current address for each party.
Yes. Any vehicle titled in your name must be claimed regardless of condition.
Yes. The license bureau requires that anything titled in your name have a matching receipt (in your name) showing that taxes were paid on that vehicle.
Missouri law states that you must claim your personal property in the county you resided in on January 1st. We would be happy to put you on our mailing list for the next year. Please contact our office at (816) 407-3520 or fill out this Change of Address form.
We need to verify that the vehicle you are tagging is going to be licensed in your name before we issue the waiver and we also need the make, model, and vehicle identification number (VIN) to assess your vehicle properly.
To qualify for a tax waiver in Clay County, you must meet one of the following requirements:
- You are new to our state.
- You are a former resident returning to Missouri from another State and no unpaid personal property taxes are due in Clay or any other Missouri County.
- You lived in Clay County on January 1st of the previous year but you did not have any personal property titled in your name.
If you meet requirement No. 1 or 2, you will need to bring your out-of-state title, application for title, or registration. If you do not have a vehicle that was registered in that state you must provide proof of residence in that state for Jan 1 of the previous year.
If you meet requirement No. 3, you must bring the title or application for title in order to receive a tax waiver.
There is no fee for a tax waiver.
According to MO State Statute 137.075 “Persons owning or holding tangible personal property on the 1st day of January shall be liable for taxes.” Personal property includes all motor vehicles, motorcycles, recreational vehicles, trailers, boats, motors, mobile homes, aircraft, farm machinery, livestock and grain.
The Assessor sends out assessment lists at the end of each year. It is your responsibility to return that list to the Assessor’s office by March 1, listing the taxable personal property you own as of January 1 of that year. Under state law, there is no provision for prorating taxes for a partial year, and you may be penalized if the form is not returned to the Assessor’s office by March 1.
If you are a new resident, or have moved, you need to contact the Clay County Assessor’s Office so that they can put you on the tax rolls.

The tax is based on the value of the vehicles you own, not on the number of vehicles you own. It is common for a person with one, more expensive vehicle to owe more tax than another person with several, less expensive vehicles. Also, the levies in your taxing district must be considered.
Yes. Please be sure to add them correctly and send the exact amount due. Be sure to include all payment stubs and write all bill numbers on your check.
The amount of tax you owe each year is based on the value of the vehicles you owned on January 1st of that year. The value of the vehicles is established by the County Assessor using a standard rate book. The assessed value of your vehicles can be found in the upper center portion of your statement. Your bill is also determined by the city in which you reside. Your tax bill may appear higher this year because city and county taxes are now on the same bill. For example: a $10,000 car will be assessed at $3,333, then your tax bill will be between $270 and $330 depending on the tax rates that apply to your address.
Your tax is based on the vehicles you owned on the first day of the tax year. Even if you no longer own the vehicles, even if you now own different vehicles, even if you now own no vehicles, you still pay tax based on what you owned on the first day of the year.
- Paid tax receipts will not be issued until all amounts appearing on your county bill have been paid—including city taxes and special assessments.
- If you owe past due taxes to your city, those past due taxes may appear on your county bill as a special assessment from your city. This lump sum assessment represents all past due taxes you owed your city, for all tax years, including all interest and penalties owed to your city.
- If you have any questions about special assessments or delinquent amounts owed to your city, you must contact your city. We are collecting an amount that was given to us by your city, and we cannot change that amount without notification from your city. However, all regular taxes on the bill may be paid, and questions about those amounts answered, at either of our office locations.
- If you pay your bill after December 31, a one-time penalty of 7% will be charged on all taxes and assessments appearing on your bill—for both your city and Clay County. Interest will accrue on all city and county taxes at the rate of 1.5% per month.
Why is my city doing this?
- Cities will save on administrative costs since they will receive their money without having to mail, track, and collect each bill.
- If there is a correction to be made on your bill, you will contact the county Assessor’s office and the change they make will affect both county and city amounts due. There will be no more need to then go to your city and make the change twice.
- With only one bill, it will be easier to manage coordinating payments coming from escrow accounts or lease companies. Most companies are already set up to pay county bills, so your city taxes will be paid at the same time.
- Cities will have a higher collection rate, giving them more money to pay for city services.
Additional notes on city taxes:
- Since city taxes will now be on your county bill, the full amount due on the bill will be higher. If you have been used to paying the two bills at different times, we understand. Clay County now takes partial payments. All payments will be pro-rated to each taxing entity until the bill is paid. After December 31, interest and penalty will continue to accrue on the reduced balance, so pay as much as you can on time.
- To address the issue of unpaid taxes for past years, any delinquent taxes you owe to your city have been added to your county tax bill as well. These amounts must be paid before you can receive a paid tax receipt for use at the DMV. We understand that this isn’t the best news you may have heard, but cities do depend on this money for day to day operations.
Responsible citizens shoulder the burden for activities that benefit all of us. We all pay to maintain highways on which we may never drive, support hospitals where we may never be admitted, and support a military that may never watch over our particular neighborhood. When schools deteriorate, so do our property values.
We will remove her name from the rolls; however, the family or the estate is responsible to pay the deceased taxpayer’s bill. We get all of our billing information from the Assessor’s office, so they should be notified as well at (816) 407-3500.
Please contact your spouse’s attorney and obtain the other half of the payment through his/her attorney. The bill will remain unpaid, and you will not be able to renew tags until it is fully paid. The Collector’s office cannot not waive taxes pursuant to a divorce decree or other court order. The Assessor’s office may be able to help you apply a divorce decree to your tax bill, but you will need to speak to them directly at 816-407-3500.
Missouri law only allows penalties and interest to be waived on delinquent taxes for active duty military paying within 6 months of returning from active duty, and in cases where the County has made an error. Please bring your military orders with you when seeking to have your penalties and interest waived. If you believe the County has made an error that entitles you to a waiver of penalties and interest, please contact our office to discuss the matter. If you do not agree with our decision, you must request a refund from the County Commission.
There is a one-time penalty of 9% charged at the time you pay the bill. Interest accrues monthly on unpaid balances at a rate of 1.5% per month.
Tax bills are normally mailed out by mid-November every year. If you do not receive a tax bill from Clay County by November 30th, please call (816) 407-3200. Missouri statutes mandate payment by December 31st whether a taxpayer receives a bill or not. Bills do occasionally get lost in the mail, but you still have an obligation to pay. Bills are currently available online 24 hours a day at https://collector.claycountymo.gov.
You must make sure that you are on the Assessor’s tax lists. Please contact the Assessor’s Office at (816) 407-3500.
All payments, at all times of year, should be mailed to:
Lydia McEvoy, Collector
1 Courthouse Square
Liberty, Missouri 64068.
Checks should be made payable to “Lydia McEvoy, Collector.”
Our Federal Tax ID number is 44-6000477.
The majority of bad checks written to the Collector’s office come from our counter payments—not online, credit card, or by mail. The Prosecuting Attorney’s office has mandated that driver’s license numbers must be recorded so that we can verify precisely who submitted the bad check. If you need to deliver a payment for anyone other than the person that signed the check, you must deposit the payment in our drop box. You cannot deliver a check to our cashiers for someone else unless your name is also on the checking account, or you can show the cashier power of attorney documentation. Drop boxes are available inside during office hours at both locations, and outside 24 hours a day / 365 days a year.
We now accept partial payments at both office locations, through the mail, and online. Payments are always applied to the oldest debt first. Interest and a penalty will continue to accrue on the unpaid balance. Making a partial payment will not prevent your property from being sold at the tax sale, nor will it stay any litigation related to collection of delinquent taxes. Please note that all amounts appearing on your personal property bill must be paid in full before the County will give you a paid receipt for use at the Department of Motor Vehicles.
YOU CANNOT GET AN IMMEDIATE RECEIPT TO USE AT THE DMV UNLESS YOU PAY IN PERSON AT OUR OFFICE LOCATIONS.
These are credit card processing fees and apply to both online and in-office payments.

Currently we accept cash, check, money orders, and cashiers checks. We accept debit card, credit card, and e-check payments online. We accept Visa, MasterCard, Discover, and American Express. If you pay in person with a paper check, the person presenting the check must present a current driver’s license, and must be authorized to sign the check. Please do not mail cash.
You no longer need a PIN number to pay online.
Yes. By state law, your tax obligation is established on January 1st. Even if you move to a different state (or county) the next day, you are still taxed for the entire year. You may move into Missouri January 2nd and not pay personal property taxes all year. You may move out of Missouri on January 2nd and pay personal property taxes for the entire year. Personal property taxes are not pro-rated.
You will not receive a bill unless you filled out an assessment form for the year being taxed. If you recently moved to Clay County, please contact the Assessor’s Office to ensure that you are properly registered. Another frequent reason why taxpayers do not receive their tax bill is that they move and fail to inform the County of their new address (inside or outside Clay County).
Go to https://collector.claycountymo.gov/ and type in your LAST NAME and FIRST NAME only. On this site, you can see your current balance, payment history, pay online using credit card or e-check (3rd party convenience fees apply). You may also print your current and past tax receipts online. This is the website where you will return to print your paid receipt after 12:00 noon on the next business day AFTER you paid online.
Please be sure that your payment is postmarked no later than December 31st. Payments postmarked after December 31st will accrue a 7% penalty and interest at a rate of 1.5% per month. County offices will be closed all weekends, Thanksgiving and the Friday after, on Christmas Day, and on New Year’s Day. Sometimes, there are additional closures during the holiday season or due to dangerous weather conditions. Please call 816-407-3200 before you come to verify that the office is open. You may also deposit your payment in our external drop boxes 24 hours a day, and these boxes will be emptied in a timely manner at the end of the year. Payments deposited after midnight December 31 will be considered LATE under Missouri law. If you use a bill payment system, or any other method of payment delivery, please note that these payments are often sent to our office without a postmark. Online bill payments that come to our office without a valid postmark will be posted as of the date printed on the check. ONLINE BILL PAY SERVICES DO NOT PROCESS CHECKS THE SAME DAY YOU REQUEST. Do not request a payment date of December 31 if you plan to pay on time. MANY POST OFFICES NO LONGER POSTMARK MAIL ON THE SAME DAY IT IS DROPPED AT THEIR LOCATION, AND MANY NO LONGER HAND CANCEL MAIL. Please do not wait until December 31 to submit payment in any form.
