Assessed Value 

Assessed Value 

Once the Appraised Value is set, the Assessed Value is a mathematical calculation. Kansas Law offers a range of assessment rates. The key rates are as follows:  

Residences 

11.5% 

Mobile Homes 

11.5% 

Personal Property 

25% 

Businesses 

25% 

Utilities 

33% 

Agricultural 

30% of Use Value 

Agricultural Improvements 

25% 

Vacant Lots 

12% 

Non-Profit Organizations 

12% 

 

In other words, if you own a business property that has an appraised value of $1 million, the property will have an assessed value of $250,000.  

There is a partial exception to this simple calculation. 

For residences, including mobile homes, the first $20,000 of Appraised Value is not subject to the school general levy. This makes residences have two assessed values for calculating taxes. The first is 11.5 percent of the total Appraised Value. The second is 11.5 percent of total Appraised Value reduced by $20,000. In other words, a $100,000 home will have an Assessed Value of $11,500 and a second Assessed Value of $9,200. This distinction will be important when calculating taxes.
