Not legal advice. Rules change. Call your county or a lawyer to check your own case.

The short answer

Missouri property taxes are due by Dec. 31 and are late on Jan. 1. Your bill is your home's market value times 19%, divided by 100, times your total local tax rate. If a bill stays unpaid, Clay and Platte counties can offer the home at a yearly tax sale on the fourth Monday in August, and Jackson County uses a court case. Jackson canceled its 2026 sale, but the taxes are still owed. Seniors and people who are behind have programs to ask about.

Key points
  • Bills are due Dec. 31. On Jan. 1 they are late, and charges start to grow.6
  • Clay and Platte hold a yearly tax sale on the fourth Monday in August. Jackson uses a court case.43, 13
  • Jackson canceled its 2026 sale. The taxes are still owed.11
  • Seniors, people with disabilities and people who are behind have programs to ask about.

Every fall, a tax bill comes for every home in Kansas City. Some people pay it and forget it. Some never see it, because the loan company pays it. And some people put it in a drawer.

That last choice can cost a lot. In Missouri, the bill is due by Dec. 31. On Jan. 1, it is late. Late bills grow. And if a bill stays unpaid long enough, the county can sell the home to get the money. That is true even if the home is paid off.6, 48

This year there is more to watch than usual. Jackson County canceled its August 2026 tax sale. It said it needs time to check its tax bills.11 Jackson says its 2026 bills go online and in the mail starting Nov. 1.15 In Platte County, a court fight is going on over a tax credit voters passed in April.56 And 2027 is a year when home values get set again.

For a home at the September 2026 middle sale price in each county, our math puts the yearly bill at about $4,220 in Jackson, $4,660 in Clay and $6,400 in Platte (using an estimated rate), before any credits. Your bill will be different. This guide shows how the bill is made, what happens if it goes unpaid, and where to get help. Every rule comes from a law, a county office or a state office. The sources are at the end.

What does property tax pay for?

Property tax here means the tax on your home and the land under it. Cars have a different tax. This guide is about the home tax.

Most of the money does not stay with the county. It goes to schools, cities, fire districts, libraries and more. Jackson County says it keeps only about 7 cents of each tax dollar.33 That county statement is from 2025. Our own check of the 2025 rates for a Kansas City home in the Kansas City school district comes out close: about 6.6 cents of each dollar.29

Three offices handle your home tax:

  • The assessor sets the value of your home.
  • The Board of Equalization hears your case if you think the value is wrong.
  • The collector sends the bill and takes the money.

How does the county set your home's value?

In Missouri, the big value check happens every two years. The assessor sets new values as of Jan. 1 of odd years, like 2025 and 2027. The same value is used again the next year, unless you build on or add to the home.12

Your tax is not figured on the full value. For homes, Missouri uses 19%. That smaller number is called the assessed value.12

Here is a made-up example. It is not a real home. Say the county thinks a home is worth $100,000. 19% of that is $19,000. The tax is figured on $19,000.

The law has a rule for big jumps. If the assessor wants to raise a home's value by more than 15%, not counting new building work, it must look at the home in person first. The law says a drive-by is not enough. You get at least 30 days to ask for a look inside.12 That matters if your home needs big repairs the street can't show.

When your value goes up, the county must tell you.39 Clay says it mails these letters around April 1 to owners whose value went up.23 Don't toss that letter.

Values can also move because of the state. In 2025, the State Tax Commission told Platte County to raise home values 15%. Platte agreed to 6.835% instead, the county says.27

How is a Missouri property tax bill figured?

Each local group sets its own tax rate, also called a levy. Your school sets one. Your city may set one. So may your fire district and library. Add them up and you get your total rate. The rate is per $100 of assessed value.

The math has three steps:

  1. Take your assessed value.
  2. Divide it by 100.
  3. Multiply by your total rate.

Back to the made-up example: $19,000 divided by 100 is 190. Pretend the total rate is $8. 190 times 8 is $1,520. That would be the bill.

Your real rate is on your bill. Rates are not the same across a county. Jackson County lists 95 tax codes for 2025. Their total rates run from $5.98 to $9.50 per $100.29

Try it yourself below. The home value starts at the September 2026 middle sale price for each county.52 The rate starts at a sourced example for each county. Move the sliders to match your bill.

Estimate a yearly bill

Pick a county. Then move the sliders. This is an estimate before any credits, special assessments or past-due amounts.

Yearly bill, before credits
Assessed value (19%)
Set aside each month

How it works: assessed value = value x 19%; bill = assessed value / 100 x total rate12, 15. Senior freeze, Platte's credit, Jackson's 15% credit and special assessments are not included. Starting values: KCRAR Sept 2026 county median sale prices52; rates from Jackson County's 2025 levy schedule29, the City of Liberty and Clay County Clerk 2025 levies34, 30, and a Platte estimate from 2024 levies listed by Platte County EDC55.

A bill can go up when your value goes up, when a rate goes up, or when new charges get added. One state rule helps a bit. When values rise across an area, the law can push rates back down so local groups don't get a windfall.40 It does not mean a bill never goes up. But a big jump in value does not always mean the same jump in the bill.

How do you appeal your home's value, and by when?

You can appeal. That means you ask someone to look again. There are three steps, in order.

Step 1: Talk to the assessor. This is often called an informal review. Bring proof, like photos, a repair quote, an appraisal or sales of homes like yours. Platte says to meet with an appraiser before June 30.28 Clay holds informal hearings in April.22

A warning for Jackson County: if you sign an agreement with the assessor on a new value, your Board appeal is canceled. You also give up the State Tax Commission step.16 Read before you sign.

Step 2: The Board of Equalization. State law says to file by the second Monday in July.37 In 2026, that was July 13. In 2027, it will be July 12. The board can lower your value, keep it or raise it. Clay and Platte take board appeals through the county clerk.22, 27 Platte's assessor page says to turn forms in to the assessor, so call first.28 One Jackson page still says "3rd Monday in June." The same page says the 2026 deadline was July 13.16 The law says July.

Step 3: The State Tax Commission. File by Sept. 30, or 30 days after the board decides, whichever is later.38

Keep paying while you appeal. The bill is still due Dec. 31. Jackson says refunds after a value cut are sent on their own. But Jackson also says it won't redo 2026 bills for appeal results until January 2027. So pay the 2026 bill in full by Dec. 31.16, 15

When are Missouri property taxes due?

The bill is due by Dec. 31. Most bills come in November. Jackson says its 2026 bills are online and in the mail starting Nov. 1.15 Platte mails bills in November and says to call if you don't have yours by the end of November.25 Liberty's city site says Clay County bills are mailed in November.34

In Missouri, the bill is due by Dec. 31. If it is not paid, it is late on Jan. 1.6

Four things trip people up:

  • No bill? You still owe it. Jackson says to call 816-881-3232 if you don't have a bill by Dec. 8.15
  • The postmark counts. A payment mailed by Dec. 31 counts as on time.41 But Jackson warns that mail drop boxes may not postmark the same day. Mail it a few days early.15
  • Pay the county directly. Clay warns about a bill-pay site called DOXO. Clay says it is not part of the county and may charge fees.21
  • Online systems go down. Clay says online payments will be down Monday, Oct. 19, from 2 a.m. to 8 a.m.21 Platte says tech trouble does not move the deadline.25

What happens if you don't pay?

On Jan. 1, the bill is late. The law calls it delinquent. From there, it grows.

State law adds a penalty of 18% of each year's late tax. If you pay before a tax sale, it can't be more than 2% a month.42 Jackson says interest, penalties and fees are added on the first day of each month.15 As a sale gets close, more costs pile on. Clay, for example, added a $135 charge to bills still late on May 4, 2026, and another $115 on June 1.20

Missouri law says the tax is tied to the land. The county does not get a court order against you as a person for the tax. It goes after the property.48

What happens next depends on your county. Jackson County uses a court case. Clay and Platte use a yearly sale run by the collector.13, 43

Use the timeline below. Pick a county. Then slide to see what can happen as months go by.

If a bill goes unpaid: what can happen, month by month

Pick a county and slide. Month 0 is Jan. 1, the day after the due date. .

    You can pay the full amount owed at any point before a sale. Month numbers are examples, not deadlines. Call your collector for your own dates.

    How does the Clay and Platte County tax sale work?

    Before a sale, the collector mails a letter. If the home's assessed value is over $1,000, a second letter comes by certified mail.43 Then the list of late properties runs in a local paper three weeks in a row.44

    The sale is the fourth Monday in August.43 In 2026, that was Aug. 24. Clay held its sale online that day.20 In 2027, the fourth Monday is Aug. 23.

    You can pay any time before the home is sold.43 Platte's 2023 brochure says up to 10 a.m. on sale day.35 Clay gets stricter as the sale gets close. After June 14, 2026, Clay took only cash, cashier's checks or money orders.20 Call early.

    How far behind before a sale? State law sets no number of years. It says late taxes are "subject to sale."43 Clay's 2026 rules say all lands with late taxes are subject to the sale.1 A Platte County Landmark story says Platte's sale covers taxes two or more years late.60 Ask your collector.

    At a first or second offering, the buyer does not get your house. The buyer gets a paper called a certificate of purchase. The Platte County Landmark, citing Platte's collector, says the buyer can't move in right away.60

    You then get time to buy it back. That is called redeeming. After a first or second offering, the law gives at least one year. You pay the bid, costs and interest. The law caps that interest at 10% a year.45 The buyer must send you a notice at least 90 days before getting a deed.46 If the buyer waits too long, past 18 months, the buyer's claim ends.47

    The time gets shorter each round. At a third offering, the time to redeem drops to 90 days. After that, a buyer gets a deed right away, with no time to redeem.7 Clay's 2026 rules say the same.1 Platte's 2023 brochure says a third-offering home can be redeemed until a deed is issued.35 Ask Platte which rule it uses now.

    How does Jackson County collect unpaid taxes?

    Jackson County works another way. Jackson says when a tax is three years old, the home can face a sale. The county may file a court case.13 State law says the collector lists these properties by April 1 and the cases are filed by June 1.8 Notice runs in the paper four times.50

    If the court rules for the county, there is usually a six-month wait before the sale can be advertised. But if the court finds a home was empty for at least six months, that wait does not apply.9 The sale is then advertised four times.10

    You can pay in full any time before the sale. Jackson says that payment must be made in person, with cash or certified funds.13 Once the home is sold, the right to buy it back is over.49

    The 2026 sale was canceled. On July 13, 2026, County Executive Phil LeVota signed an order canceling the August sale. The order says there will be no Jackson County tax sale in 2026. A new sale can be set only after the county checks and fixes tax bills tied to the 2022 values, and the order points to 2027.11 KCTV reported that more than 1,000 homes had been set for that sale.61 The county's FAQ says no new date has been announced.14 The court's sale page lists both August 2026 sale weeks as canceled.19

    The taxes are still owed. Charges keep adding up. This is a pause, not a pass.

    What help is there if you can't pay?

    Jackson County payment contract. If you are behind, ask about a contract. Jackson says it starts with a down payment of 30% or 10%, depending on the property, then 11 monthly payments. Interest and fees keep adding up. If you miss a payment from January to May, the property goes back on the August sale list.17 Jackson's pages don't agree on when you can sign one. One says after the county files a case. Another says only after a court judgment.17, 13 Call 816-881-3232.

    Clay and Platte. We did not find a payment plan for late taxes on either county's site. Call and ask.

    Senior tax freeze (62 and older). It is a credit that covers most increases in your home tax after a base year. Each county runs its own.32

    • Jackson: Apply by Dec. 31. Jackson says you don't need to renew each year right now.15
    • Clay: Apply Jan. 1 to March 31. Renew each year. Clay says new taxes voters approve still show up on the bill.24
    • Platte: The 2026 window is Oct. 1 to Dec. 31. Platte's page says both that the program needs a yearly application and that you don't reapply unless you move. Call the county clerk to be sure.26

    Jackson quad pay (62 and older). Jackson lets seniors split the county real estate bill into four payments with no interest if paid on time. You must be caught up on past years first. It can't be used if a loan company pays your taxes.15

    MO-PTC, the state credit. Some call it the circuit breaker. It can give back part of your home tax if you are 65 or older, 100% disabled, or 60 or older and getting Social Security as a surviving spouse. State law raised the limits starting with 2026. A homeowner can count up to $1,550 in tax, and the income limit for a married couple who owned their home all year is $48,000.31 The Department of Revenue's web page still shows the older $1,100 limit.36 Claims for 2026 are filed in 2027. Ask the Department of Revenue for your numbers.

    Platte's 5% credit. Platte voters passed a homestead credit on April 7, 2026. It limits yearly increases to 5% or inflation, whichever is more.62, 56 The collector's office plans to start it in 2027. Two residents sued on Sept. 29 to make it start on 2026 bills. Platte's judges stepped aside from the case on Oct. 8.56, 57 A separate statewide case over the law was heard on July 29. We found no ruling as of Oct. 11.59 Jackson and Clay are not part of this credit. If you live in Platte, look at your bill closely.

    What the headline numbers don't show

    Three things the big numbers leave out. Each chart is built from official rate sheets we saved for this guide.

    1. The "7 cents" holds up, for one Kansas City address

    Jackson County's 7-cent figure is from a 2025 county news release33. We checked it against the 2025 rate sheet. For a Kansas City home in the Kansas City school district (tax code 001), the county's own line is 6.6 cents of each dollar. Schools get 65.2 cents29. The split is different in other tax codes.

    Bar chart: where a Kansas City tax dollar goes in Jackson County tax code 001, 2025. Schools 65.2 cents, county 6.6 cents.
    Takeaway: most of a Kansas City home tax goes to schools; the county keeps about 6.6 cents. Source: Jackson County 2025 Real Estate Tax Levy Schedule, accessed Oct. 11, 2026. Saving KC calculation.

    2. Same county, same price, very different bills

    A county median price does not tell you your bill. Jackson County has 95 tax codes. On the same $285,000 value, 2025 rates give bills from $3,240 to $5,146 a year. That is a gap of $1,90629, 52. Where you live inside the county matters, not just what your home is worth.

    Histogram of yearly bills on a $285,000 value across Jackson County's 95 tax codes, from $3,240 to $5,146.
    Takeaway: on one value, Jackson bills spread across about $1,906. Each tax code counts once, no matter how many homes it has. Sources: Jackson County 2025 levy schedule; KCRAR Sept 2026. Saving KC calculation.

    3. When values go up, rates can go down

    Values rose in the 2025 reassessment, but the total rate for a home in Liberty fell from 7.70 in 2024 to 7.19 in 202534. Rates also fell in 2021. In 2023 the change was small. This fits the rollback rule40, but a rate can also move because voters or boards change a levy. A lower rate does not always mean a lower bill, because the value may have gone up more.

    Line chart of the Liberty, Missouri total property tax rate, 8.52 in 2018 to 7.19 in 2025.
    Takeaway: Liberty's total rate went from 8.52 in 2018 to 7.19 in 2025. Source: City of Liberty Property Taxes page, accessed Oct. 11, 2026; 2025 lines match the Clay County Clerk 2025 levy book.

    What we could not show: a typical Platte County total rate from an official source (we use an estimate), and how many homes are in each Jackson tax code.

    What dates should homeowners watch next?

    • Nov. 1: Jackson 2026 bills go online and in the mail.15
    • November: Platte and Clay bills mail.25, 34
    • Platte credit case: a new judge has to be named.56
    • Dec. 8: No Jackson bill yet? Call 816-881-3232.15
    • Dec. 31: Bills due. Last day to apply for the Jackson senior credit and for Platte's 2026 senior credit window.15, 26
    • Jan. 1, 2027: Unpaid 2026 bills are late. New home values are set as of this date.6, 12
    • Jan. 1 to March 31, 2027: Clay senior relief window.24
    • January 2027: Jackson plans to start redoing 2026 bills for appeal results.16
    • July 12, 2027: Board of Equalization deadline (second Monday in July).37
    • Aug. 23, 2027: Clay and Platte tax sales (fourth Monday in August).43
    • 2028: Jackson County voters elect an assessor for the first time. Missouri voters passed Amendment 2 on Aug. 4, 2026.2, 58

    No statewide property tax question is on the Nov. 3, 2026 ballot. A proposed freeze on home values did not make it.2, 54

    About this guide

    This guide covers Missouri only: Jackson, Clay and Platte County. It goes with the Saving KC video "Missouri Property Taxes, Made Simple" (Oct. 20, 2026). Each rule was checked against the current text of Missouri law and the county and state pages listed above on Oct. 11, 2026. Where official pages disagree, we say so. Bill estimates use the formula the counties publish and are not a quote of any real bill. No stories or quotes in this guide are made up.

    Not legal advice. This guide is to help you learn. It is not legal or tax advice. Rules change. Call your county or a lawyer to check your own case.

    FAQ

    Frequently asked questions

    When are property taxes due in Missouri?

    By Dec. 31. An unpaid bill is late (delinquent) on Jan. 1, and penalties and interest start to add up (RSMo 140.010). A payment mailed and postmarked by Dec. 31 counts as on time, but mail it a few days early because drop boxes may not postmark the same day.

    How is property tax calculated in Missouri?

    For a home, the county takes 19% of the market value to get the assessed value, divides it by 100, and multiplies by your total local tax rate. Example: a $100,000 home has a $19,000 assessed value; at a total rate of $8 per $100, the bill is $1,520.

    How much are property taxes in the Kansas City area?

    For a home at the September 2026 median sale price, our estimate is about $4,220 a year in Jackson County, $4,660 in Clay and $6,400 in Platte (using an estimated rate), before credits. Rates vary inside each county: Jackson's 95 tax codes run from $5.98 to $9.50 per $100 of assessed value.

    What happens if you don't pay property taxes in Missouri?

    The bill is late on Jan. 1 and grows each month. The tax is tied to the property, so the county goes after the home, not you personally. Clay and Platte counties offer late properties at a yearly sale on the fourth Monday in August. Jackson County uses a court case once a tax is three years old, followed by a sale.

    How many years can you go without paying property taxes in Missouri?

    There is no single number. State law says late taxes are subject to sale and sets no minimum number of years for the Clay and Platte sales; a Platte County Landmark story says Platte's sale covers taxes two or more years late. Jackson County says a home can face a court case when a tax is three years old. Ask your collector about your property.

    Is Jackson County having a tax sale in 2026?

    No. On July 13, 2026, County Executive Phil LeVota signed an order canceling the August 2026 sale, and the order points to 2027. No new date has been announced. The taxes are still owed, and charges keep adding up.

    Can you get your house back after a tax sale in Missouri?

    In Clay and Platte, after a first or second offering you have at least one year to redeem by paying the bid, costs and interest capped at 10% a year (RSMo 140.340). At a third offering, the time drops to 90 days. In Jackson County, the right to buy the home back ends once it is sold.

    What is the deadline to appeal a property assessment in Missouri?

    File with the county Board of Equalization by the second Monday in July: July 13 in 2026 and July 12 in 2027 (RSMo 137.275). If you disagree with the board, file with the State Tax Commission by Sept. 30 or 30 days after the board decides, whichever is later. Keep paying your bill while you appeal.

    Is there a property tax freeze for seniors in Missouri?

    Yes, counties run a senior tax credit for homeowners 62 and older that covers most increases after a base year. Jackson takes applications through Dec. 31; Clay takes them Jan. 1 to March 31 and needs a yearly renewal; Platte's 2026 window is Oct. 1 to Dec. 31. The state MO-PTC credit can also give back part of the tax for some people 65 and older or disabled.

    When do Jackson County property tax bills come out?

    Jackson County says its 2026 bills go online and in the mail starting Nov. 1. If you do not have a bill by Dec. 8, call the collector at 816-881-3232. You still owe the tax even if the bill never arrives.
