How Property Taxes Are Calculated
A Simple Two-Step Formula
The Kansas Property Tax Formula
Kansas property taxes are calculated in two distinct steps. First, the assessed value is determined. Then, the mill levy is applied to that assessed value to compute the actual tax bill.
Step 1 — Find the Assessed Value
Appraised Value × Assessment Rate = Assessed Value
Step 2 — Calculate the Tax Bill
Assessed Value × Mill Levy ÷ 1,000 = Property Tax
Worked Example — Residential Property
Here is a simple example using a Kansas residence valued at $200,000 and a combined mill levy of 130 mills:
| Step | Calculation | Result |
|---|---|---|
| Appraised (Fair Market) Value | — | $200,000 |
| Residential Assessment Rate | $200,000 × 11.5% | $23,000 (assessed value) |
| Apply the Mill Levy | $23,000 × 130 ÷ 1,000 | $2,990 (annual tax bill) |
Key Terms Defined
Appraised Value
The county appraiser’s estimate of the property’s fair market value — what it would sell for between a willing buyer and a willing seller.
Assessment Rate
A percentage set by Kansas law that varies by property class (e.g., 11.5% for residential). It converts appraised value to assessed value.
Assessed Value
Appraised value multiplied by the assessment rate. This is the value used to compute the actual tax bill.
Mill Levy
The combined tax rate set by all local taxing units (school, county, city, etc.) within your area. One mill equals $1 of tax per $1,000 of assessed value.
