Missouri Attorney General Catherine Hanaway announced on Wednesday that her office had won two significant legal battles over property taxes, closing out the years-long fallout from Jackson County’s troubled 2023 reassessments and defeating a constitutional challenge to the state’s Homestead Property Tax Credit law, the Missouri Attorney General’s Office reported.
The twin rulings land at a moment when household budgets across the state are stretched thin, addressing the tens of thousands in Jackson County who were hit with steep assessment spikes without the legally required notice. The Jackson County settlement forces the county to drop its appeal and keep its corrected assessment rolls in place, while the court victory in Alois Kirchhofer, et al. v. State of Missouri preserves statutory shields that blunt sudden, excessive property tax increases statewide.
Jackson County Agrees to Drop Appeal, Keep Corrected Rolls
The Jackson County litigation arose when county authorities relied on defective assessment methods, neglected state legal requirements, and overlooked mandatory notice deadlines for sharp tax hikes imposed on tens of thousands of property owners. The controversy became one of the largest local tax disputes in recent Missouri history and helped spur voters to approve a constitutional amendment requiring the direct election of all county assessors.
After the state intervened, it ordered Jackson County to correct residential assessments, roll back many of the largest increases, and comply with Missouri law going forward. The county challenged that order in court, but the state prevailed at trial. Pursuant to the settlement publicized November 4, county leaders consented to abandon their appeal, keep adhering to the state’s remedial directive, preserve the revised assessments, and attest that the mandated changes were applied to the 2023 and 2024 assessment rolls.

In a parallel class action lawsuit, Jackson County separately agreed to reimburse taxpayers who were unlawfully over-assessed, and the court has preliminarily approved that class action settlement, according to First Alert 4.
“At a time when families across Missouri are stretching every dollar and watching their household budgets more closely than ever, government has a responsibility to safeguard taxpayers, not make life harder for them,” Hanaway said. “When local governments get it wrong, Missouri families should not be the ones who pay the price.”
Court Rejects Every Challenge to Homeowner Tax Protections
The second victory came in Alois Kirchhofer, et al. v. State of Missouri and Catherine L. Hanaway, a lawsuit seeking to eliminate protections for Missouri homeowners facing excessive and sudden property tax increases. A judge ruled entirely in favor of the state, rejecting every constitutional challenge and upholding the Homestead Property Tax Credit law.
The court endorsed the state’s reasoning that the statute bears a rational relationship to the legitimate governmental interest of shielding homeowners from sharp tax surges while tackling pervasive assessment-compliance shortcomings. The ruling also cited evidence showing that more than 90 Missouri counties and the City of St. Louis were assessing property below state compliance standards — a finding that keeps pressure on local assessors far beyond Jackson County. Assistant Attorneys General Clayton Weems and Sean McDowell briefed the case for the state.
For St. Louis-area taxpayers, the practical effect is that the state statutory safeguards designed to cap or blunt sudden assessment spikes remain intact, and the Jackson County resolution sets a compliance precedent that reinforces accountability for county assessors across Missouri, First Alert 4 reported.
Why This Matters for Missouri Homeowners Now
Property taxes are one of the largest fixed costs for Missouri families, and assessment errors compound quickly: a flawed 2023 valuation doesn’t just raise one year’s bill, it can anchor inflated taxes for years unless the roll is corrected. That is exactly what the state’s corrective order and the county’s agreement to certify the 2023 and 2024 assessment rolls are designed to fix.
The Kirchhofer ruling carries its own weight. Had the plaintiffs won, the Homestead Property Tax Credit protections could have been dismantled just as more than 90 counties and the City of St. Louis were found to be assessing below state compliance standards — leaving homeowners with fewer protections against excessive and sudden property tax increases.
The cases are now resolved on the state’s terms — the appeal is dismissed, the corrective order stands, reimbursements for over-assessed taxpayers move forward under preliminary court approval, and the homeowner protections survive intact. For families watching their budgets, the message from Jefferson City is that the state will keep enforcing assessment law and defending tax relief, Hanaway’s office said.
