About Property Taxes in Kansas
Kansas property taxes are administered at the county level. Residential property is appraised at its market value and then assessed at 11.5% of that appraised value. Commercial and industrial property is assessed at 25%. The county appraiser determines values, the county clerk calculates tax rates, and the county treasurer collects taxes. Kansas property taxes are levied for the current year and collected in two installments that straddle the calendar year. Rates vary significantly by county and by the number of overlapping taxing districts.
Payment & Assessment
Kansas property taxes are paid in two equal installments: First half: Due December 20 of the current tax year Second half: Due May 10 of the following year A penalty of 1% per month (up to 12%) applies to late payments. Most counties offer online payment through the county treasurer's website. Contact your county for payment options.
