How Kansas assessment appeals generally work (state framework reviewed 2026-08-02 from official Kansas sources): County appraisers generally determine January 1 fair market value for locally assessed property and then apply the constitutional or statutory percentage for the property's class. Assessment percentages vary by class; residential real property is generally assessed at 11.5%, while commercial, industrial, agricultural, vacant-lot, and other classes use different percentages or valuation standards. A property owner may appeal a valuation notice to the County Appraiser for an informal meeting or use the separate payment-under-protest route when available. A final county determination may be appealed to the Kansas Board of Tax Appeals, with single-family residential property generally proceeding through its Small Claims and Expedited Hearings Division before the regular division. Judicial review is available under the governing statutes and decision notice.
Kansas deadline framework: A real-property equalization appeal is generally due within 30 days after the county mails the valuation notice. A Board of Tax Appeals petition is generally due within 30 days after mailing of the county's informal decision or applicable final determination. Payment-under-protest, personal-property, third-party-appraisal, state-appraised, and later-review routes use distinct triggers and deadlines.
Local variation in Kansas: Kansas's 105 county appraisers administer notices, informal meetings, records, and local submission methods. Property class determines the assessment percentage, and agricultural, public-utility, personal-property, payment-under-protest, and single-property-appraisal matters follow different valuation or procedural rules.
Before relying on a date: Resolve the county, property class, January 1 tax year, valuation-notice mailing date, and whether an equalization, payment-under-protest, or appraisal route is being used, then verify the county form and receipt deadline, informal-meeting result, correct Board of Tax Appeals division, petition deadline, and any later review requirements.
