Who sends the property tax bill in Johnson County, and how do you pay it?
The bill comes from the Johnson County Treasury, Taxation and Vehicles (County Treasurer). The value it is based on is set by a separate office, the Johnson County Appraiser's Office, which is who to ask if the value looks wrong. For how to look up and pay the bill, go to the county's own payment information.
The Johnson County Appraiser values homes and mails value notices by March 1; the county's Treasury, Taxation and Vehicles department, which serves as both County Clerk and Treasurer, computes the levies for every local taxing body and sends one bill. Mail payments to the county's bank lockbox address printed on the statement; a payment sent without the bill stub may be charged a $5 duplicate bill fee. Online payments cost $0.50 by e-check or 2.25% by card and take two to three business days to post. Several cities in the county run their own property tax relief programs, separate from the county's.
When are property taxes due in Johnson County?
For the 2026 bill, Johnson County splits the bill into 2 payments, the first due December 20, 2026 and the last May 10, 2027. A first half not paid by the December due date draws interest from December 20 at a rate set by state law each year (the state's statutory rate plus five percentage points), and can be paid late with that interest until May 10. Any tax still unpaid on May 11 draws interest from May 10 until paid. Real estate tax not paid by July 31 is published in the newspaper with a $15 publication fee, a tax lien is placed on the property on the first Tuesday in September, and if the tax stays unpaid through the redemption period the county files a foreclosure suit and the property is auctioned. Not receiving a statement does not excuse interest.
| Payment | Due | Note |
|---|---|---|
| First half (or full amount) | December 20, 2026 | Tax statements are mailed in mid-November. You may pay the full year or the first half by this date. December 20, 2026 is a Sunday. Kansas law (K.S.A. 79-2004) moves a real property tax due date that falls on a Saturday or Sunday to the Treasurer's next regular business day, so in 2026 the first half is on time if received by Monday, December 21, 2026; the county applied the same rule last year, when it set the first-half deadline at Monday, December 22, 2025. The county says payment must be received in its office by the due date, and mailed payments go to a bank lockbox in St. Louis, so mail early or pay online. |
| Second half | May 10, 2027 | May 10, 2027 is a Monday. Second-half notices are mailed at the beginning of April. |
From Johnson County's published schedule, checked September 23, 2026. If a date falls on a weekend or holiday, the county's own rules on the next business day apply.

How to appeal your Johnson County property assessment
In Johnson County you appeal to the Johnson County Appraiser's Office (informal appeal or payment under protest); its decision can then be appealed to the Small Claims Division of the Kansas Board of Tax Appeals (BOTA). The deadline: There are two ways to appeal a value at the county level, and you may use only one per tax year. An informal appeal must be filed within 30 days of the date the Notice of Appraised Value was mailed; notices go out on or before March 1, so the 2026 window closed at the end of March. The route still open for 2026 is paying under protest: file the Payment Under Protest application with your payment between November 1 and December 20 (December 21 in 2026, since the 20th is a Sunday). If a mortgage company pays at least half your taxes, the protest is due by January 31, 2027, and if you pay after these dates, the protest must be filed when you pay. A protest sent without the correct payment, including any interest and fees, is rejected. If you are not satisfied with the county's result, you have 30 days to appeal to BOTA's Small Claims Division. How to file. Checked September 23, 2026 against the official appeal rules.
