Jackson County Property Tax Appeal — Missouri

The appeal application window for 2026 will open May 1, 2026, and run until July 13, 2026. You must file your formal appeal with the Jackson County Board of Equalization during this window. If you're not satisfied with the Board's decision, you have a right to appeal to the State Tax Commission by September 30 or 30 days after the final action of the board of equalization — whichever is later. Missing these deadlines means you'll have to wait until the next assessment cycle to appeal.

Jackson County offers an online portal for filing property tax appeals through their Board of Equalization system. You'll need your property information and assessment notice to complete the online application. The portal typically opens on May 1st for the appeal season. As of June 30, 2026, the Board of Equalization will be located only at 1300 Washington, Kansas City, MO. If you have trouble with the online system, you can also file in person or by mail at this address.

Jackson County offers several property tax exemption programs, including the Missouri Property Tax Credit for eligible residents. Jackson County's Senior Property Tax Credit Program provides tax relief for eligible senior citizens. The exact amount of savings depends on your income level, property value, and specific qualifications. You should contact the Jackson County Assessment Department directly at(816) 881-3232 to determine your eligibility and potential savings amount, as these programs have specific income and residency requirements.

A hearing will be scheduled where the board will hear evidence from the assessor and any evidence you might have regarding the value of the property which is the subject of the appeal. The Jackson County Board of Equalization is an independent Board composed of citizen taxpayers of Jackson County. Its mission is to fully and fairly equalize the value of all real and tangible personal property in the County for purposes of taxation. You should bring comparable sales data, photographs of your property's condition, repair estimates, or a recent appraisal to support your case. The hearing is your opportunity to present why you believe your assessment is incorrect.

The amount you can save through a successful property tax appeal depends on how much your property was overassessed. During the 2023 assessment cycle, assessment values spiked an average of 30% in Jackson County, prompting a flood of appeals. Any residential property owner whose property assessment increased more than 15% in 2023 will receive a tax credit. That tax credit will appear on their 2026, 2027 and 2028 tax bills. With Jackson County's effective tax rate of 1.19%, a $10,000 reduction in assessed value could save you approximately $119 annually in property taxes.

You should determine what you believe to be the value of your property and gather and present evidence that supports that value. Such evidence could include photographs, the recent sale of your property, or the oral testimony of someone who has done a recent appraisal of your property. The most effective evidence includes recent sales of comparable properties in your neighborhood, professional appraisals, photos showing any damage or needed repairs, and contractor estimates for necessary repairs. Make sure all evidence relates to the property's condition as of January 1st of the assessment year.

A property's assessed value can't be raised by more than 15% without a physical inspection, which is why the Missouri State Tax Commission ordered the county to roll back property assessment increases that were greater than 15%. Many homeowners will see their assessment drop this year because of the retroactive 15% cap on assessment increases. This cap is designed to protect homeowners from dramatic year-over-year increases in their property taxes, ensuring that assessments rise gradually rather than in large jumps that could create financial hardship.

If you cannot file your appeal online, you may file your Complaint for Review of Assessment and the decision letter from the Board of Equalization by downloading and completing the form using the link below and sending it via email to Legal@https://stc.mo.gov. However, you typically must go through the county Board of Equalization first. If you purchased the property within thirty (30) days of the statutory deadline for filing appeals to the board of equalization, or later in the year, and did not have a chance to appeal to the board of equalization, you will need to send your proof of purchase. The STC notice explains homeowners can file a new appeal to the STC if their assessment notice comes late. If taxpayers had less than 30 days' notice to file their BOE appeal, they can file an appeal directly with the STC.
