Kansas Commercial Property Tax Appeals

Kansas taxes commercial property on 25% of its value while homes pay 11.5% — then hands owners the friendliest procedure in our footprint: the county carries the burden of proof, the Board can't raise your value, and a win now protects you for five years.

Why Kansas Is Different

A Heavy Ratio, and the Tools to Fight It

Kansas appraises every property at fair market value each January 1 — but the constitution taxes classes at very different fractions of that value: commercial and industrial real property at 25%, residential at 11.5%. Stack the 25% ratio on consolidated levies of roughly 99–151 mills and commercial owners carry an effective rate of about 2.8% of market value in Wichita, 2.5–2.9% in Johnson County, and 3.5% or more in some Sedgwick County suburbs — a burden the Lincoln Institute's 50-state study puts in the top dozen nationally for Wichita.

What makes Kansas unusual is how much of the procedure runs in the owner's favor. By statute, the county appraiser must prove the value is correct — no presumption of correctness attaches to the assessment. The Board of Tax Appeals cannot raise your value in your own appeal. And under legislation signed this year, a reduction won on appeal now anchors your value for five years: sharp model-driven increases trigger a mandatory adjustment or an independent fee-simple appraisal.

The catch is discipline. The spring window is short — 30 days from a notice that lands around March 1 — the December alternative is mutually exclusive with it, and for leased commercial property the burden of proof follows the income disclosure: handle that exchange wrong and you've handed the county its case. Kansas rewards owners who know the sequence.

The Appeal Calendar

Every Date That Matters

Kansas gives commercial owners two bites at the same apple — a spring equalization appeal and a December payment under protest — but only one per property per year.

Real Propertyland & buildings
  1. By March 1
    Valuation notices mailed
    County appraisers must notify every owner of the year's appraised value on or before March 1 (K.S.A. 79-1460). The value speaks as of January 1.
  2. +30 days
    Informal equalization appeal
    The appeal — a request for an informal meeting with the county appraiser — must be filed within 30 days of the notice mailing (K.S.A. 79-1448). This meeting is the required first step, and it's also where the leased-property income-disclosure clock starts.
  3. By May 20
    County's written decision
    Informal meetings conclude by May 15 and the appraiser's final written determination — with reasons, if unfavorable — is due by May 20.
  4. +30 days
    Board of Tax Appeals
    Appeal to BOTA within 30 days of the county's decision. Commercial property under $3 million may elect the small claims division (hearing within 60 days, decision within 30, de novo appeal to the regular division available). Filing fees run $100–$500 by value tier — and no fee is charged while a prior appeal on the property is still pending.
  5. December 20
    The second route: payment under protest
    Owners who missed the spring window can file a written protest with the county treasurer at the time of the December 20 tax payment (or the May 10 second half; January 31 if an escrow agent pays). Mutually exclusive with the equalization appeal — one route per property per year.
  6. +30 days from final order
    Judicial review
    After BOTA's full opinion, an aggrieved party may petition the Kansas Court of Appeals — or the taxpayer may instead elect a trial de novo in district court, where the county again bears the burden on valuation.
Personal Propertyequipment & fixtures
  1. January 1
    Assessment date — for what’s left
    Machinery and equipment acquired after June 30, 2006 is categorically exempt (K.S.A. 79-223) — two decades of replacement cycles later, most ordinary equipment is off the rolls. Still taxable: pre-2006 machinery in service, “Other”-subclass property such as aircraft and heavy trucks, and oil & gas interests. Items under $1,500 retail cost when new are exempt outright.
  2. March 15
    Rendition due — but only once
    Since July 1, 2024 (SB 410), no annual re-filing: once an initial rendition is on file, you file again only when something changes. Written extension requests by March 15 must be granted for adequate reasons. Late filing accrues 2% per month to a 10% cap; failure to file draws a flat 12.5%.
  3. May 1
    Notice of Value mailed
    Two months after real property’s March 1 notice — and only two weeks before the appeal cutoff.
  4. May 15
    Appeal deadline — a hard date, not a window
    Real property gets 30 days from its notice; personal property gets until May 15, full stop. With notices legal through May 1, that can mean fourteen days to engage the county appraiser for the informal meeting.
  5. December 20
    The second chance — payment under protest
    Missed May 15? Pay by December 20 and file a payment-under-protest with the treasurer. One path per property per year — equalization appeal or PUP, never both.

Statutory basis: K.S.A. 79-1460 (notices), 79-1448 (informal appeal; May 20 determination), 79-1609 (BOTA; county's burden), 74-2433f (small claims), 79-2005 (payment under protest), 74-2426 (judicial review). Statutory dates falling on weekends roll to the next business day. Commercial machinery and equipment acquired after June 30, 2006 is exempt (K.S.A. 79-223), so Kansas commercial appeals are, in practice, real-property appeals. Personal property: renditions K.S.A. 79-306 (SB 410 file-once rule, eff. July 1, 2024); notices 79-1460 (May 1); appeals 79-1448 (May 15); exemptions 79-223, 79-201w.

How the Bill Is Built

25% of Value, and Who Has to Prove It

Taxable value is appraised value × the class ratio, and the class spread does the damage: a $10 million commercial building carries $2.5 million of assessed value; the same value in homes carries $1.15 million. At Wichita's 2025 consolidated levy of about 113 mills, that building pays roughly $282,000 a year — with the Sedgwick County suburbs running meaningfully higher and Johnson County slightly lower.

The procedural framework is where Kansas turns owner-friendly. The county must prove its number by a preponderance of the evidence — the statutes say expressly that no presumption favors the appraiser. For leased commercial property there's a critical exception: the burden sits with you unless you furnish a complete three-year income-and-expense statement within 30 days after the informal meeting — and a single-property appraisal effective January 1 puts the burden back on the county. That disclosure decision — what, when, and whether — is the strategic heart of a Kansas appeal.

Since the Supreme Court's 2022 Walmart decision, methodology fights (build-to-suit rents, dark-store comps) are decided on the weight and credibility of the appraisal evidence rather than admissibility — in the 2023 NFM of Kansas case, BOTA discarded a county appraisal outright for USPAP violations, and the Court of Appeals affirmed. In a credibility regime, the quality of the record is the case.

The Class Spread
25%
Commercial real property is assessed at 25% of appraised value — homes at 11.5%. More than twice the taxable base per dollar of value.
Wichita consolidated~113 mills (2025)
Overland Park / Olathe~99–115 mills
Sedgwick Co. suburbs~139–151 mills
Effective commercial~2.5–3.8% of value
Market 2025 Consolidated Levy Effective Commercial Rate (25% × mills)
Wichita (USD 259) 112.8 mills ≈ 2.8% of market value
Overland Park ≈ 99–105 mills ≈ 2.5–2.6%
Olathe ≈ 115 mills ≈ 2.9%
Sedgwick County suburbs ≈ 139–151 mills ≈ 3.5–3.8%

2025 levies (taxes payable December 2025 / May 2026); ranges reflect school district and city differences. Beginning in tax year 2026 the statewide 1.5-mill building levies are eliminated (2025 SB 35), trimming every total slightly. Wichita ranks in the top dozen nationally for commercial property tax in the Lincoln Institute / MCFE 50-state study.

Where Appeals Are Won

The Grounds That Actually Move Bills

Kansas procedure hands owners real leverage — if the sequence is handled correctly:

The county's burden

The appraiser must prove the valuation correct by a preponderance of the evidence, with no presumption in the county's favor — at the hearing panel, small claims, BOTA, and district court alike. The owner starts even, not behind.

The disclosure lever

For leased commercial property, furnishing three years of income and expenses within 30 days after the informal meeting keeps the burden on the county — and a January 1 single-property appraisal returns it there. Mishandle the exchange and the burden is yours.

The five-year shield

Under 2026 legislation, an appeal reduction protects you for five years: any model-driven jump over 5% forces the county to adjust to your appeal or commission an independent fee-simple appraisal. One win anchors half a decade of bills.

Credibility after Walmart

The Supreme Court overruled the old evidence-exclusion rule: valuation fights are now won on appraisal quality and USPAP compliance, not admissibility motions. NFM of Kansas shows BOTA will discard a non-compliant county appraisal entirely.

No-risk escalation

BOTA cannot raise your value above the county's final determination, small claims offers a fast track under $3 million, fees top out at $500 — and no fee applies while a prior appeal on the property is pending.

The December second chance

Missed the 30-day spring window? Payment under protest at the December 20 installment reopens the fight — with the same informal meeting and BOTA path. One route per property per year, so choose deliberately.

Kansas FAQ

Common Questions

When is the deadline to appeal property taxes in Kansas?
County appraisers mail valuation notices by March 1, and the equalization appeal — a request for an informal meeting with the county appraiser — must be filed within 30 days of the notice mailing. The appraiser's written decision is due by May 20, and an appeal to the Board of Tax Appeals is due within 30 days after that decision. If you miss the spring window entirely, Kansas offers a second route: a payment-under-protest filed with the December 20 tax payment (or the May 10 second half). You cannot use both routes for the same property in the same year.
How is commercial property assessed in Kansas?
All real property is appraised annually at fair market value as of January 1, but the constitution assesses classes at different percentages: commercial and industrial real property at 25% of appraised value, residential at 11.5%. The same million dollars of value carries more than twice the taxable base in a commercial building as in a home. On 2025 consolidated levies that produces effective commercial rates of roughly 2.8% of market value in Wichita, 2.5–2.9% in Johnson County, and 3.5% or more in some Sedgwick County suburbs.
Who has the burden of proof in a Kansas appeal?
The county — which is unusual. By statute, the county appraiser must produce evidence proving the validity and correctness of the valuation by a preponderance of the evidence, and no presumption exists in favor of the appraiser. One critical exception: for leased commercial property, the burden shifts to the taxpayer unless you furnish the county a complete income-and-expense statement for the three prior years within 30 days after the informal meeting — and submitting a single-property appraisal with a January 1 effective date returns the burden to the county. Managing that disclosure correctly is a core part of Kansas appeal strategy.
Can the county raise my value because I appealed?
No — the Board of Tax Appeals may not increase the appraised value above the county's final determination in a taxpayer appeal, so escalating carries no raise risk. Better still, 2026 legislation extended Kansas's post-appeal protection: for reductions finally determined on or after January 1, 2026, if the county's model pushes your value up more than 5% in any of the following five years (excluding new construction, a change of use, or reclassification), the appraiser must either adjust the value based on your appeal or obtain an independent fee-simple appraisal. A win now anchors your value for half a decade.
Did the Walmart dark-store case change Kansas appeals?
Yes, materially. In 2022 the Kansas Supreme Court overruled the Prieb rule that had excluded build-to-suit lease evidence as a matter of law. Kansas remains a fee-simple valuation state, but methodology disputes now go to the weight and credibility of the appraisal evidence, not its admissibility — so cases are won by appraisal quality, USPAP compliance, and credibility before the Board of Tax Appeals rather than by evidentiary knockouts. For owners, that raises the bar on preparation: the record you build is the case.
What does a Kansas property tax appeal cost?
SVA works on pure contingency — no retainers, no minimums, and no fee unless your taxes are reduced. Our rate scales down from 20% to as low as 8% as the property's annual tax liability grows, versus the industry-standard flat 25%. Kansas state filing fees are modest — small claims runs $100–$200 and the regular division $200–$500 by value tier — and with the county carrying the burden of proof and no raise risk at the Board, Kansas is one of the most owner-friendly appeal venues we practice in. See the full fee matrix.
