How to Appeal Your Property Tax in Kansas: Step-by-Step Guide
Kansas reassesses property values every year, and the state’s mill levy system means even small changes in appraised value can significantly affect your annual tax bill. The county appraiser sets your property’s value as of January 1 each year, and you receive a Change of Value notice in early March. If you believe the appraised value exceeds your home’s actual market value, you have the right to appeal — and in Kansas, the process is more straightforward than in many states.
The typical Kansas homeowner who successfully appeals their property tax assessment saves $300 to $800 per year. On a $300,000 home in Johnson County with a combined mill levy of 125 mills, a 10% reduction in appraised value reduces the annual tax bill by about $430. Over 5 years, that’s $2,150 in savings from a single appeal. Here’s exactly how the Kansas property tax appeal process works, step by step.

Understanding Kansas Property Tax Assessments
Kansas uses a unique assessment system that differs from most states. Residential property is assessed at 11.5% of appraised market value. The county appraiser determines the “fair market value,” and the assessed value (11.5% of that figure) is what the mill levy is applied to.
| Assessment Component | Details |
|---|---|
| Assessment Ratio (residential) | 11.5% of appraised value |
| Assessment Ratio (commercial) | 25% of appraised value |
| Assessment Ratio (agricultural) | 30% of use value |
| Valuation Date | January 1 of each year |
| Notice Mailed | March 1 (approximately) |
| Appeal Deadline (informal) | Within 30 days of notice |
| Appeal Deadline (formal) | June 15 or 30 days after notice, whichever is later |
How the Mill Levy Works
Kansas property taxes are calculated by multiplying the assessed value by the total mill levy rate. One mill equals $1 per $1,000 of assessed value. Most Kansas properties face combined mill levies between 100 and 170 mills, depending on county, city, school district, and special districts. Here’s an example:
| Step | Calculation | Result |
|---|---|---|
| Appraised Value | Set by county appraiser | $300,000 |
| Assessed Value (11.5%) | $300,000 × 0.115 | $34,500 |
| Total Mill Levy | 125 mills (Johnson County example) | 125 |
| Annual Tax | $34,500 × 0.125 | $4,313 |
Step 1: Review Your Change of Value Notice
Kansas county appraisers mail Change of Value notices in early March. The notice shows your property’s new appraised value, the previous year’s value, and the percentage change. Review this notice carefully and compare the appraised value to what your home would actually sell for on the open market as of January 1.
Your appeal should focus on one argument: the appraised value exceeds the property’s fair market value. Understanding how your assessed value affects monthly housing costs is easier with our mortgage calculator. You are not appealing the mill levy rate or the 11.5% assessment ratio — those are set by state law and cannot be changed through individual appeals.
Step 2: Gather Evidence
Strong evidence is the key to a successful appeal. Kansas appraisers and appeal boards respond to factual, market-based evidence rather than emotional arguments. Compile the following:
| Evidence Type | How to Get It | Impact |
|---|---|---|
| Recent comparable sales | MLS data, Zillow, county records | Strongest evidence; 3-5 comps within 1 mile |
| Professional appraisal | Hire appraiser ($300–$450) | Very strong; independent valuation |
| Property condition issues | Inspection reports, repair estimates | Moderate; documents deferred maintenance |
| Photos of defects | Foundation cracks, roof damage, wear | Moderate; visual evidence of condition |
| Neighboring property comparisons | County appraiser website | Moderate; shows assessment inconsistencies |
| Listing history | MLS records | Strong if home was listed/sold below assessed value |
Finding Comparable Sales
The most effective evidence is 3 to 5 recent sales of similar properties within a half-mile of your home. Look for homes with similar square footage (within 10%), the same number of bedrooms and bathrooms, similar age, and comparable lot size. Adjust for differences: if a comp has a finished basement and yours doesn’t, note the value difference. Kansas county appraiser websites publish recent sale prices, which you can access for free.
Step 3: File an Informal Appeal with the County Appraiser
The first level of appeal is an informal review with your county appraiser’s office. This is typically a phone call or in-person meeting where you present your evidence and discuss the valuation. Most counties schedule these within 30 days of the Change of Value notice.
This step is worth the effort. Roughly 40% to 50% of informal appeals in Kansas result in some reduction. County appraisers would rather resolve disputes informally than face formal hearings, and they’ll adjust values when presented with legitimate comparable sales data. Even if the appraiser doesn’t grant your full request, they may agree to a partial reduction that saves you hundreds per year. If you’re planning to sell your home, keep in mind that a lower assessed value doesn’t reduce your market value — it reduces only your tax burden.
Step 4: File a Formal Appeal (If Informal Fails)
If the informal appeal doesn’t resolve the issue, you can file a formal appeal with your county or district appeal board. The deadline is June 15 or 30 days after the informal appeal decision, whichever is later. Kansas has two formal appeal paths:
Small Claims Division
For residential properties appraised under $2 million, the Small Claims Division of the Board of Tax Appeals (BOTA) handles appeals. The process is simpler and less formal than the regular division. You present evidence, the county presents its case, and a hearing officer issues a decision. No attorney is required, though you can hire one if you prefer.
Regular Division (BOTA)
For properties appraised at $2 million or above, or if you want a more formal process, appeals go to the Regular Division of BOTA. This involves a more structured hearing with sworn testimony and formal rules of evidence. Attorneys are common but not required.
| Appeal Level | Deadline | Cost | Typical Duration |
|---|---|---|---|
| Informal (county appraiser) | 30 days from notice | Free | 1-2 weeks |
| Formal Small Claims (BOTA) | June 15 or 30 days after informal | $0–$25 filing fee | 2-4 months |
| Regular Division (BOTA) | June 15 or 30 days after informal | $25 filing fee | 4-8 months |
| District Court | 30 days after BOTA decision | Court fees + attorney | 6-12 months |
Step 5: Attend Your Hearing
If you proceed to a formal hearing, prepare a clear, organized presentation. Bring copies of all evidence for the hearing officer and the county representative. Present your case simply: state the appraised value, explain why you believe it’s too high, and present your comparable sales data. County appraisers will present their reasoning and evidence. The hearing officer will issue a written decision, typically within 30 to 60 days.
County-by-County Appeal Success Rates
| County | Avg. Appeal Volume (annual) | Informal Success Rate | Formal Success Rate |
|---|---|---|---|
| Johnson County | 3,500+ | ~45% | ~35% |
| Sedgwick County (Wichita) | 2,200+ | ~50% | ~40% |
| Shawnee County (Topeka) | 1,400+ | ~48% | ~38% |
| Douglas County (Lawrence) | 800+ | ~42% | ~33% |
| Wyandotte County (KCK) | 1,100+ | ~52% | ~42% |
Tips for a Successful Appeal
- Focus on fair market value: Your only argument is that the appraised value exceeds what the home would sell for. Don’t argue about tax rates, mill levies, or how much you can afford.
- Use recent sales: Comps should be from the 12 months preceding the January 1 valuation date. More recent sales carry more weight.
- Account for condition: If your home has deferred maintenance, foundation issues, or an older roof that comparable homes don’t share, document the cost difference.
- Be respectful and factual: County appraisers and hearing officers respond to data, not frustration. Present your evidence calmly and clearly.
- Consider hiring an appraiser: A professional appraisal ($300–$450) provides independent evidence that carries significant weight. If you believe the overvaluation exceeds $20,000, the appraisal cost is justified by the potential tax savings.
Common Mistakes in Kansas Property Tax Appeals
Understanding what doesn’t work is as important as knowing what does. The most common mistake is arguing that your taxes are too high without challenging the appraised value. The appeal process only addresses the county appraiser’s determination of your property’s fair market value. You cannot appeal the mill levy rate, the 11.5% assessment ratio, or the decision of any taxing authority to levy taxes. If your appraised value is accurate but you still think taxes are too high, your recourse is through the political process (voting on mill levy questions, attending taxing authority budget hearings) rather than the appeal process. If you’re still in the buying process, factor property tax levels into your affordability calculations using our affordability calculator.
The second most common mistake is using emotional arguments rather than data. Statements like “I can’t afford this” or “my neighbor’s taxes are lower” don’t carry weight unless backed by comparable sales data showing that your property’s appraised value exceeds its actual market value. Your neighbor may have a lower tax bill because their home is smaller, older, or appraised at a lower value — not because the county is treating you unfairly.
The third mistake is missing deadlines. The informal appeal window (30 days from your Change of Value notice) and the formal appeal deadline (June 15 or 30 days after informal decision) are strict. Late filings are generally not accepted, and you’ll have to wait until the next assessment cycle to appeal. Set calendar reminders for early March (when notices arrive) and mark the deadlines immediately when you receive your notice.
Kansas Homestead Refund
Separate from the appeal process, Kansas offers a Homestead Property Tax Refund for income-qualified homeowners. If your household income is below $37,750 (2025 threshold), you may qualify for a refund of a portion of your property tax. The refund is filed with your Kansas income tax return using Schedule K-40H. This doesn’t change your assessment but directly reduces your tax burden.

Frequently Asked Questions
When is the deadline to appeal property taxes in Kansas?
For the informal appeal to your county appraiser, you have 30 days from the date of your Change of Value notice (typically mailed in early March). For the formal appeal to the Board of Tax Appeals (BOTA), the deadline is June 15 or 30 days after the informal appeal decision, whichever is later. Don’t wait — start the process as soon as you receive your notice. Missing the informal deadline doesn’t prevent a formal appeal, but the informal process is faster and resolves most cases.
How much can I save by appealing my Kansas property tax?
The average successful appeal reduces the appraised value by 5% to 15%. On a $300,000 Johnson County home with a 125-mill levy, a 10% reduction saves approximately $430 per year. Over 5 years, that’s $2,150. On a $200,000 Wichita home with a 140-mill levy, a 10% reduction saves about $322 per year. The savings are proportional to your home’s value and your county’s mill rate. Use our property tax calculator to model different scenarios.
Do I need a lawyer to appeal property taxes in Kansas?
No. The vast majority of residential property tax appeals in Kansas are handled by homeowners without attorneys. The informal appeal is a simple conversation with the county appraiser. The Small Claims Division of BOTA is designed for non-lawyers and follows informal procedures. Hiring an attorney makes sense only for high-value properties (above $1 million) or complex situations. Some property tax consulting firms will handle the entire appeal process for a contingency fee (25%–40% of first-year savings), which eliminates upfront cost but reduces your net savings.
Can I appeal every year?
Yes. Kansas reassesses property annually, and you can appeal every year if you believe the valuation is too high. However, frequent appeals without strong evidence can damage your credibility with the county appraiser’s office. The best practice is to appeal when your property’s value has clearly been overestimated — for example, when comparable sales are significantly below your assessed value, or when your property has condition issues that reduce its market value.
What if the county raises my value after I appeal?
Kansas law does not allow the county to increase your assessed value as retaliation for filing an appeal. However, the BOTA hearing officer can set the value at any level supported by evidence, including higher than the original assessment, if the county presents evidence that the value was actually too low. This is extremely rare in practice — in the vast majority of cases, the result is either a reduction or no change. You cannot withdraw an appeal once a formal hearing is scheduled, so be confident in your evidence before proceeding to the formal level.
