How Kansas Property Taxes Are Calculated

Aug 4

Key Takeaways

Kansas property taxes are calculated using a simple two-step formula.
Most property is taxed based on its assessed value, which is derived from its appraised market value.
Agricultural land is an important exception. It is generally appraised using its use value rather than its market value.
Three numbers determine most property tax bills: the property’s appraised value, its assessment rate, and the local mill levy.
Understanding these concepts makes it easier to evaluate appraisal notices, budget proposals, and local tax increases.

Why It Matters

Property taxes are one of the largest expenses many Kansans pay each year, yet many homeowners don’t understand how their tax bill is calculated.

The process is actually straightforward. Once you understand a few basic terms, you can estimate your own property taxes and better understand why they change from year to year.

Step 1: Determine the Appraised Value

For most property in Kansas, the county appraiser estimates the property’s fair market value—what it would likely sell for on the open market as of January 1 of the tax year.

For example:

Appraised value: $300,000

This is not the amount on which your taxes are calculated.

Agricultural land is different. Rather than being valued based on its market price, qualifying agricultural land is generally appraised according to its use value—its capacity to produce agricultural income under Kansas law. As a result, farmland may have a market value that is much higher (or lower) than the value used for property tax purposes.

Step 2: Calculate the Assessed Value

Kansas law applies an assessment rate to the appraised value.

For residential property, the assessment rate is 11.5%.

Example:

Appraised value: $300,000
Assessment rate: 11.5%

Assessed Value = $300,000 × 11.5%

Assessed Value = $34,500

The assessed value—not the market value—is the figure used to calculate property taxes.

Step 3: Apply the Mill Levy

A mill equals $1 of tax for every $1,000 of assessed value.

Each taxing authority adopts its own mill levy during the annual budget process. Those individual levies are combined into one total mill levy for your property.

Your combined mill levy may include taxes for:

County government
City government
School district
Community college
Library
Fire district
Cemetery district
Other special taxing districts

Suppose your combined mill levy is 125 mills.

Your annual property tax would be calculated as follows:

Assessed Value × Mill Levy ÷ 1,000

$34,500 × 125 ÷ 1,000 = $4,312.50

Your estimated annual property tax would be approximately $4,313.

Why Property Taxes Change

There are generally only two reasons your property tax bill changes.

1. Your Property Value Changes

If the county determines your property’s market value has increased, your assessed value also increases.

Even if the mill levy stays exactly the same, your property taxes will rise because they are being applied to a larger assessed value.

2. The Mill Levy Changes

Local governments adopt new budgets every year.

If your city, county, school district, or another taxing authority increases its mill levy, your property taxes may increase even if your property’s value stays the same.

Sometimes both the property’s value and the mill levy increase in the same year, resulting in a larger tax increase.

Why Two Similar Homes May Pay Different Taxes

Two homes with identical market values may have different property tax bills.

That’s because they may be located in different combinations of taxing jurisdictions.

One home may be inside a city with a higher mill levy or belong to a different school district or special taxing district than another home only a few miles away.

The Bottom Line

Kansas property taxes are calculated using a straightforward process:

Determine the property’s appraised value (or use value for qualifying agricultural land).
Apply the appropriate assessment rate to calculate the assessed value.
Apply the combined mill levy to determine the annual property tax.

Understanding those three steps makes it much easier to follow local budget discussions, evaluate proposed tax increases, and understand your annual property tax statement.

Definitions

Appraised Value: For most property, the county appraiser’s estimate of the property’s fair market value as of January 1 of the tax year.

Use Value: A method of valuing qualifying agricultural land based on its productivity and agricultural use rather than its market value. Kansas uses use-value appraisal to ensure farmland is taxed according to its agricultural production rather than its potential development value.

Assessed Value: The taxable value of a property after applying the assessment rate established by Kansas law.

Assessment Rate: The percentage of a property’s appraised value that is subject to taxation. Residential property is assessed at 11.5%. Other classes of property—including commercial, industrial, personal, and agricultural property—are subject to different assessment rates established by state law.

Mill: One dollar of tax for every $1,000 of assessed value.

Mill Levy: The total property tax rate adopted by all taxing authorities serving a property, including the county, city, school district, community college, library, and other special districts.

Taxing Authority: A governmental entity or special district that is authorized to levy and collect property taxes.

Revenue Neutral Rate (RNR): The mill levy that would generate the same amount of property tax revenue from existing property as the previous year. If a taxing authority proposes to exceed the Revenue Neutral Rate, Kansas law generally requires public notice and a public hearing before adopting the higher levy.

Property Tax Formula:

Appraised Value × Assessment Rate = Assessed Value

Assessed Value × Mill Levy ÷ 1,000 = Annual Property Tax
