Is Kansas Property Tax Constitutional?
A legal question with more nuance than it first appears
Questions about the constitutionality of property taxation usually involve several different legal issues at once. One question is whether Kansas has constitutional authority to impose a property tax at all. A separate question is whether a particular assessment or collection procedure was carried out lawfully. A third concerns what happens when taxes go unpaid — including the government's authority to enforce a lien and ultimately seek a court-ordered sale.
Kansas law expressly provides for property taxation, tax liens, and judicial foreclosure. At the same time, both the Kansas Constitution and the U.S. Constitution place real limits on how governments tax and take property. This page walks through what the law actually says on both sides, rather than assuming either conclusion.
What the Kansas Constitution Says
Article 11, Section 1 of the Kansas Constitution directs the Legislature to establish a "uniform and equal basis of valuation and rate of taxation" for taxable property, and establishes the property classifications and assessment percentages described in The History of Property Tax in Kansas. These provisions have governed assessment and taxation since January 1, 2013.
Two Ways to Read the Same Constitution
| Property tax is constitutionally authorized | Constitutional authorization has limits |
|---|---|
| Article 11 expressly directs the Legislature to tax property. | Article 11 also requires that taxation be uniform and equal — a specific requirement, not just a general grant of power. |
| The Constitution itself sets out property classifications and assessment percentages. | A particular assessment could still be challenged if it doesn't comply with those requirements. |
| Kansas statutes implement this framework in detail. | Taxing authorities remain subject to due process and other constitutional protections in how they apply that framework. |
| On this reading, a Kansas property tax system existing at all is not, by itself, unconstitutional. | On this reading, the existence of taxing power doesn't resolve whether a specific tax, assessment, or collection action was carried out constitutionally. |
These aren't opposing camps so much as two different questions — whether Kansas may tax property at all, and whether a specific instance of taxing it was done lawfully. Both are real questions; they're just not the same question.
What Happens When Property Taxes Go Unpaid
Kansas law sets out a specific statutory process for delinquent property tax, not an informal seizure:
- K.S.A. 79-2401a gives owners a redemption period after a delinquent tax sale — three years for a homestead and most real estate, one year for abandoned buildings. During that window, partial payment of back taxes can extend the redemption further.
- K.S.A. 79-2801 requires the county attorney or county counselor to file an action in district court if property remains unredeemed — a judge, not just a county office, has to order the foreclosure and sale. The statute also sets out how affected owners must be notified (personal service, or service by publication with a published property description).
In short: Kansas statutes describe a lien-and-judicial-foreclosure system, with a multi-year redemption window and a required court proceeding — not the government simply taking a home without process.
The U.S. Constitution and Tyler v. Hennepin County
Federal constitutional protections apply here too. The Fifth Amendment bars taking private property for public use without just compensation, and that protection applies to state and local governments as well as the federal government.
Tyler v. Hennepin County (2023) — the U.S. Supreme Court ruled 9–0 that a Minnesota county violated the Takings Clause by selling a home to satisfy a $15,000 tax debt and keeping the full $40,000 sale price, rather than returning the roughly $25,000 surplus to the homeowner. The Court held that keeping value beyond what was actually owed is a taking requiring compensation.
It's worth being precise about what this case did and didn't decide. Tyler did not hold that property taxation itself is unconstitutional, or that tax foreclosure itself is unconstitutional. It addressed a narrower, specific question: what happens to the surplus value once a legitimate tax debt has already been satisfied. That distinction matters for evaluating any constitutional argument about property tax — the ruling is directly relevant to how a foreclosure sale's proceeds are handled, not to whether a state may tax property at all.
Breaking the Question Down
Rather than asking only "is property tax unconstitutional," it's more precise to ask what specific government action is actually being questioned:
- The tax itself — does the Constitution authorize this type of tax? (Kansas: yes, expressly, under Article 11.)
- The valuation — was the property valued according to law?
- The classification — was the property placed in the correct constitutional class?
- Uniformity — were comparable properties treated the same way?
- Notice — were the required notices and procedures followed?
- Lien enforcement & foreclosure — did the process required by K.S.A. 79-2401a and 79-2801 actually get followed?
- Surplus value — under Tyler, did the government keep more than what was actually owed?
Separating the question this way makes it possible to have a real conversation about constitutional limits on property taxation without conflating "Kansas may tax property" with "every specific tax action is automatically lawful" — they're genuinely different claims, and conflating them weakens arguments on either side.
This page is educational information, not legal advice. It doesn't determine whether a particular assessment, lien, or foreclosure was lawful — that depends on the specific facts, statutes, and court decisions involved. If you believe your own valuation or tax proceeding was handled incorrectly, see How to Appeal Your Valuation, and talk to an attorney for anything beyond that.
