The 2026 window to appeal the spring valuation notice (30 days from March 1, 2026) has closed; paying under protest at the December 20, 2026 or May 10, 2027 deadline is the route still open for 2026.

When are property taxes due in Sedgwick County?
For the 2026 bill, Sedgwick County splits the bill into 2 payments, the first due December 20, 2026 and the last May 10, 2027. If the first half of real property tax is not paid on time, that first half starts drawing interest (K.S.A. 79-2004); the second half is still due May 10. The state sets the rate for each calendar year. For calendar year 2026 it is 13% a year on late real property tax (15% on a late amount of $10,000 or more), so late days in late December 2026 are charged at 13%. The rate for calendar year 2027 has not been published yet, so the rate on a balance still unpaid after December 31, 2026 is not known today. Tax still unpaid after May 10 draws interest from May 10. For personal property the 2026 rate is 8%, and missing December 20 makes the full year's tax due, plus interest.
| Payment | Due | Note |
|---|---|---|
| First half (or full amount) | December 20, 2026 | Tax statements are mailed in November; the Appraiser's tax calendar sets December 15 as the latest date the Treasurer sends them. 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) says that when a real property tax due date falls on a Saturday or Sunday, it moves to the Treasurer's next regular business day, so in 2026 the first half is on time if paid by Monday, December 21, 2026. |
| Second half | May 10, 2027 |

How to appeal your Sedgwick County property assessment
In Sedgwick County you appeal to the Sedgwick County Appraiser's Office (informal meeting with an appraiser); its decision can then be appealed to the Kansas Board of Tax Appeals (BOTA). The deadline: To appeal the value on your valuation notice, you must file within 30 days of the date the county mailed the notice. The 2026 notices were mailed March 1, 2026, so that window closed at the end of March. The route still open for 2026 is paying under protest: file the Treasurer's protest form when you pay the first half or full amount by the December 20, 2026 deadline, or when you pay the second half by May 10, 2027. The Treasurer accepts a protest only if the first half or full amount was paid on time. If a mortgage company pays your tax, you have until January 31, 2027 to file the protest. A value can be appealed only once per tax year, so if you appealed your notice this spring you cannot also protest it. A protest leads to an informal meeting with the Appraiser's Office; a BOTA small claims appeal of that result must be filed within 30 days of the date the results were mailed. How to file.
