How is property tax calculated in Kansas?

Kansas first multiplies your home's appraised value by the 11.5% residential assessment ratio to get assessed value, then multiplies that by your local mill levy. One mill equals $1 of tax per $1,000 of assessed value. So a $250,000 home has $28,750 of assessed value, and a 120-mill levy produces about $3,450 before exemptions.

What is the Kansas residential assessment ratio?

Residential property in Kansas is assessed at 11.5% of its appraised market value. Other property classes use different ratios — for example commercial real property is assessed at 25% and most personal property at varying rates. This estimator uses the 11.5% residential ratio.

A mill levy is the property tax rate expressed in mills, where one mill is one-thousandth of a dollar ($1 per $1,000 of assessed value). Your total levy is the sum of the rates set by the county, city, school district, and any special districts. Combined Kansas levies often run from roughly 100 to 160 mills depending on location.

Is there a Kansas homestead exemption?

Yes. Kansas exempts the first portion of a residence's appraised value from the statewide 20-mill school finance levy (the exemption amount is indexed and is around $42,000 of appraised value). This estimator applies that exemption against 20 of your mills so it does not over-state the school-levy portion. Separate refund programs also exist for seniors and low-income owners.

Will this match my exact tax bill?

It is a close estimate. Your actual bill depends on the precise appraised value, your exact combined mill levy, and any additional exemptions or special assessments. Use your county appraiser's value and your tax statement's mill rate for the most accurate figure, and treat this as a planning tool.

This Kansas property tax estimator turns your home’s appraised value into an annual tax estimate using the state’s real mechanics: the 11.5% residential assessment ratio, your county mill levy, and the homestead exemption against the statewide 20-mill school levy. Enter your value and mill rate to see the estimated bill.

How it works

Kansas taxes assessed value, not market value, at your local mill rate:

Assessed value = appraised value × 11.5% School-levy exemption = homestead exemption × 11.5% × 20 mills ÷ 1000 Annual tax = (assessed value × total mills ÷ 1000) − school-levy exemption credit

One mill is $1 of tax per $1,000 of assessed value. The homestead exemption removes the first portion of appraised value (around $42,000) from the statewide 20-mill school finance levy, which this estimator credits back so the bill is not overstated.

Notes and tips

Use the appraised (market) value from your county appraiser, not your purchase price.
Find your combined mill levy on your county tax statement — it sums county, city, school, and special-district rates.
The 11.5% ratio is residential only; commercial property is assessed at 25%.
Seniors and low-income owners may qualify for additional refund programs not modeled here.

Worked example

A $250,000 home in an area with a 130 mill levy:

Assessed value = $250,000 × 11.5% = $28,750
Gross tax = $28,750 × 130 ÷ 1000 = $3,737.50
School-levy homestead credit ≈ $42,000 × 11.5% × 20 ÷ 1000 = about $96.60
Estimated tax ≈ $3,737.50 − $96.60 = $3,640.90

Note: Estimate only. Actual bills depend on exact appraised value, your precise mill levy, and any special assessments or exemptions. Verify with your county appraiser and tax statement.
