Understanding Your Property Taxes
A quick guide to navigating the Sedgwick County tax system.
Appraisal Value
This is the county's estimate of your property's total fair market value. It is the sum of the land value and the improvements value. This number dictates your overall tax burden.
Assessed Value
You are not taxed on the full appraisal value. In Kansas, residential properties are assessed at 11.5% of their appraised value. For example, a $100,000 home has an assessed value of $11,500.
Land vs. Improvements
Land is the value of the dirt itself. Improvements refer to anything built on that land, such as your house, a detached garage, or an inground pool.
The Mill Levy & The Math
A "mill" is $1 of tax for every $1,000 of assessed value. Your base tax is calculated using this exact formula:
(Assessed Value × Mill Levy) ÷ 1,000 = Tax
Special Assessments
In addition to standard taxes, your bill may include "specials". These are fixed, flat charges to pay for neighborhood infrastructure like newly paved roads, sewer lines, or lakes, rather than taxes based on your home's actual market value.
Important Deadlines
County appraisal notices are usually mailed around March 1st. You strictly have 30 days to file an informal appeal. Property tax payments are split into two halves: the first is due Dec 20th, and the second on May 10th.
How to Appeal
You can appeal once per year via two methods: an Informal Appeal (form on back of March 1 notice, due in 30 days) or Payment Under Protest (with your Dec 20/May 10 tax payment). Submit evidence (private appraisals, comps, damage photos) via the county's Smart File portal or to [email protected] before your hearing. Learn more →
