Here is exactly how to appeal your property taxes in Kansas in 2026, including deadlines, procedures, and tips for building a winning case.
How Kansas Property Tax Assessments Work
Kansas assesses property at 11.5% for residential. The valuation date is January 1, meaning your property's value is based on market conditions as of that date. Valuation notices mailed by March 1.
The fiscal year runs January 1 - December 31. Tax bills are calculated by multiplying your assessed value by the local mill rate (or tax rate), which is set by your county, city, school district, and other taxing authorities.
Key Deadlines for 2026
| Event | Deadline/Date |
|---|---|
| Valuation date | January 1 |
| Assessment notices mailed | Valuation notices mailed by March 1 |
| Appeal deadline | Within 30 days of receiving the valuation notice (typically by march 31) |

Step-by-Step: How to Appeal Your Kansas Property Tax Assessment
Step 1: Review Your Assessment Notice
When you receive your notice, check every detail. Verify the square footage, lot size, number of bedrooms and bathrooms, year built, and any special features. Errors in property characteristics are the easiest wins in an appeal because the facts speak for themselves.
Step 2: Research Comparable Sales
Look for 3-5 homes similar to yours that sold near the valuation date (January 1) for less than your assessed value. Good comps share your neighborhood, approximate size, age, and condition. The closer the match, the stronger your case.
Step 3: File Your Appeal
File your appeal with the County Appraiser (informal), then County Board of Tax Appeals (BOTA small claims or regular) within 30 days of receiving the valuation notice (typically by March 31). In most Kansas counties, you can file by mail, in person, or online (check your county assessor's website). Include a written explanation of why you believe your assessment is too high, along with your supporting evidence.
Step 4: Prepare Your Evidence
Strong evidence includes:
- Comparable sales data: Recent sales of similar properties at lower values
- Property condition issues: Foundation problems, outdated systems, needed repairs, environmental issues
- Photos: Document any defects or conditions that reduce your property's value
- Equity arguments: Show that comparable properties in your area are assessed lower than yours
- Independent appraisal: A recent professional appraisal showing a lower value
Step 5: Attend Your Hearing
Present your case clearly and concisely. Stick to facts and data. Bring copies of all evidence for the board members. Be respectful but firm. If you have a professional appraisal or contractor estimates for repairs, those carry significant weight.
Step 6: Further Appeals If Needed
If you disagree with the County Appraiser (informal), then County Board of Tax Appeals (BOTA small claims or regular)'s decision, you can escalate to Kansas Board of Tax Appeals, then district court. Each level of appeal has its own deadlines, so act quickly if you want to continue.

Tips for a Successful Kansas Property Tax Appeal
Focus on Comparable Sales
The single most persuasive piece of evidence is comparable sales data showing similar homes sold for less than your assessed value. Boards and assessors deal in market data. Give them solid numbers.
Check for Property Record Errors
Assessors work from property records that may contain mistakes. Wrong square footage, extra bathrooms, incorrect lot size, or a missing condition note can inflate your value. Verify everything against your actual property.
Document Property Condition Issues
If your home needs a new roof, has foundation issues, or has other problems that a buyer would negotiate on, document them with photos and repair estimates. The assessor may not know about these issues.
File Every Year
Even if you won last year, your assessment can go up again this year. Make annual appeals part of your routine. There is no penalty for appealing, and your assessment cannot go up as a result of your appeal in most jurisdictions.
