Kentucky
Kentucky's constitution requires property be assessed at fair cash value; 2026 brought both a split-rate enablement law for Louisville and a legislative push for assessment caps that would require amending that same clause.
Overview
Kentucky's property tax system runs on a single constitutional principle: Section 172 of the Kentucky Constitution, titled "Property to be assessed at fair cash value — Punishment of assessor for willful error," requires that "property shall be assessed at its fair cash value."[1] That uniformity requirement — every property valued at what it would actually sell for, with no class-based or age-based carve-outs — is the fixed point against which both of Kentucky's major 2026 property-tax stories have to be read. One story moved toward the wiki's core policy: a spring 2026 law gave Louisville Metro new authority to tax land and improvements at different rates. The other pulled the opposite way: a legislative push to cap or freeze property tax assessments, which — because it would create exactly the kind of class-based departure from fair-cash-value assessment Section 172 forbids — would require amending the constitution.
HB 607 and Louisville's Split-Rate Authority
In April 2026, Kentucky's legislature overrode a gubernatorial veto to enact HB 607, which lets the Louisville Metro Council adopt a revenue-neutral split-rate property tax within the city's Urban Services District. The wiki's full account of that law — its statutory mechanism, the veto override, and Louisville Metro Council's subsequent move to adopt land/improvement classifications under it — is at The 2026 State Land Value Tax Enablement Wave; this page does not restate that sourcing. HB 607 is enabling legislation, not an enacted tax, and it operates entirely within Section 172's fair-cash-value requirement: it lets Louisville tax land and improvements at different rates, not at different bases of valuation, so it raises no uniformity-clause conflict of the kind the assessment-cap proposals below do.
The Assessment-Cap Debate
A separate and, in 2026, more contested proposal in Frankfort would freeze a homeowner's property tax assessment at age 65 — on top of the existing homestead exemption, which already reduces the assessed value of homes owned by residents 65 or older or with a total disability by a fixed, inflation-adjusted amount. Other versions circulating in the legislature would cap annual assessment growth at a fixed percentage (for example, 3% a year) for all owners. Because Section 172 requires fair-cash-value assessment for every property, any of these caps or freezes would require amending the state constitution.[1]
The state policy group Kentucky Center for Economic Policy, in a report by Jason Bailey and Dustin Pugel, argues against the cap proposals and for targeted, ability-to-pay alternatives instead.[2] Its September 2026 report contends that freezing or capping assessments would shift Kentucky's uniform, wealth-based system toward one that favors properties in appreciating neighborhoods over those in stagnant ones, favors wealthier homeowners (whose larger, faster-appreciating homes would see the largest frozen-value savings) over working-class ones, and favors long-tenured older owners over younger, more mobile households — while removing revenue that funds local schools and services, which the report states draw roughly half of Kentucky's collected residential property tax revenue.[2] Its central illustrative figures — that a $50,000 home's owner would save only a few dollars a year from an age-65 freeze while a $2 million home's owner would save thousands, and that homes over $400,000 hold a disproportionate share of total assessed value in the state — are the organization's own analysis of Census American Community Survey data, not independently replicated findings.[2] The report proposes income-based "circuit breaker" relief (a refund when a property tax bill exceeds a set share of household income, used in 29 states), low-interest deferral programs for seniors (used in 12 states), and administrative modernization of the county Property Valuation Administrator assessment cycle as alternatives that target aid to residents genuinely unable to pay without departing from fair-cash-value assessment or cutting revenue to schools and local services.[2]
Georgist Assessment
Kentucky's assessment-cap debate is a live, in-progress instance of a pattern this wiki documents at length elsewhere: freezing or capping assessed value rather than taxing current market value is the mechanism behind Proposition 13, California's 1978 property-tax revolt, whose acquisition-value system created large, persistent disparities between otherwise identical properties depending only on purchase date. A Kentucky assessment freeze tied to owner age, rather than purchase date, would produce the same structural effect by a different trigger — value frozen for one class of owner while the rest of the tax base continues to track the market — and, like Proposition 13, which wrote acquisition-value assessment into California's constitution by initiative, it could only be adopted by amending the constitution, since Section 172 forbids it in statute.
The uniformity principle in Section 172 is also the precondition, not an obstacle, for any land-based tax. A split-rate or land value tax depends on assessors being able to value land and improvements separately and accurately at current market value; a constitution that already commits the state to fair-cash-value assessment — rather than acquisition value, a class-based cap, or an age-based freeze — is the more favorable starting point for the kind of reform HB 607 enables in Louisville. Kentucky's 2026 divide is therefore not a coincidence: the same year produced both a move that depends on accurate, uniform assessment (split-rate enablement) and a move that would carve an exception into it (the assessment-cap proposals). KCEP's own preferred alternatives — circuit breakers and deferral rather than frozen assessments — track the design responses this wiki documents for the asset-rich, cash-poor objection to land value taxation: targeting relief to households that genuinely cannot pay in cash, without exempting the underlying value from eventual capture.
