This joint resolution proposes a constitutional amendment that (1) extends the maximum interval between mandatory property reappraisals from four years to five; (2) caps year‑to‑year increases in the assessed value of owner‑occupied homesteads to the prior calendar year’s Consumer Price Index for Urban Consumers (CPI‑U), except for value added by construction or improvements; and (3) creates a permanent exemption from ad valorem taxation for residential properties whose owners have held a homestead exemption and paid all ad valorem taxes for thirty or more years.
For property owners the measure promises slower growth in assessed values and, for long‑time owners, a path to full exemption. For taxing authorities it means an immediate squeeze on taxable base growth and longer intervals between market resets, raising questions about revenue forecasting, tax shifts, and implementation mechanics for assessors and local finance officers.
At a Glance
What It Does
The amendment changes the constitution to require reappraisals no less frequently than every five years, caps annual assessed‑value increases on qualifying homesteads to the prior year’s CPI‑U (excluding increases from improvements), and adds a blanket exemption for homesteads meeting a 30‑year ownership and tax‑payment condition.
Who It Affects
Owner‑occupied homestead property owners in Louisiana, parish assessors and collectors, school districts and other local taxing entities that rely on ad valorem revenue, and prospective homebuyers who do not yet qualify for the 30‑year exemption.
Why It Matters
The proposal locks in taxpayer protections tied to inflation while reducing the frequency of systemwide revaluations—two changes that reduce revenue growth potential and complicate local budget planning. It also introduces a long‑term exemption that can materially shrink local tax bases over time.

What This Bill Actually Does
The amendment rewrites parts of Article VII of the Louisiana Constitution governing assessments and exemptions. It leaves the basic method of assessing property as a percentage of fair market value intact but changes how often assessors must revisit values: instead of being reappraised at intervals of not more than four years, the constitution would allow up to five years between reappraisals.
That slows the cadence at which market increases are captured in the tax rolls.
For owner‑occupied homesteads the amendment establishes an annual ceiling on how much the assessed value may rise in any year: the average annual change in the Consumer Price Index for All Urban Consumers for the previous calendar year—commonly described as ‘CPI‑U.’ The cap does not apply to value increases caused by new construction or improvements, so renovations and additions can still trigger larger reassessments.The amendment also adds a new, narrow exemption: any residential property for which the owner has both held a homestead exemption and paid all ad valorem taxes for thirty or more years becomes exempt from future ad valorem taxation. The text ties the exemption to the owner’s record of claiming the homestead and tax payment history, not to the property itself, which raises practical recordkeeping questions for assessors.Finally, the resolution removes an existing constitutional provision that allowed a phased‑in approach to large reappraisal increases (the paragraph being repealed provided for phasing additional tax liability where assessments rose sharply).
The amendment takes effect January 1, 2027 and applies to tax years beginning on or after that date.Taken together, the changes slow recognition of market gains, cap assessed‑value growth for many homeowners to inflation, and create a path to full exemption for very long‑term owners—while shifting administrative and fiscal consequences onto local governments and assessors who must implement the new rules and absorb the revenue effects.
The Five Things You Need to Know
Reappraisal interval: the constitution would require reappraisals no more frequently than every five years (changing the current four‑year ceiling to five).
CPI cap: assessed value increases for homesteads would be limited annually to the prior calendar year’s CPI‑U percentage.
Improvements carve‑out: increases in assessed value that result from construction or improvements are excluded from the CPI cap.
30‑year exemption: a residential property becomes exempt from ad valorem tax if an owner has held a homestead exemption and paid all ad valorem taxes for 30 or more years.
Repeal of phase‑in: the amendment repeals the existing constitutional paragraph that provided for phasing in large assessment increases for homesteads.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Maintains fair‑market value assessment structure
This provision leaves in place the basic rule that assessed value is a percentage of fair market value and must be uniform across the state for the same class of property. Practically, it preserves the assessment framework; the amendment’s changes operate within that system rather than replacing valuation methodology.
Extends maximum reappraisal interval to five years
Amends the language that currently caps reappraisal frequency at four years and increases that cap to five years. The operative practical effect is to permit parish assessors one additional year between systemwide revaluations, delaying the automatic capture of market movements in assessed values and potentially smoothing year‑to‑year tax roll volatility.
Caps annual homestead assessed‑value increases to CPI‑U
Adds a new constitutional paragraph that limits year‑over‑year increases in the assessed valuation of properties receiving the homestead exemption to the prior year’s CPI‑U percentage. The paragraph expressly excludes from the cap any value increase attributable to construction or improvements. That requires assessors to segregate market appreciation from value added by physical change when calculating allowable increases.
Creates a 30‑year homestead tax exemption
Adds a new exempt category: residential property where the owner has both held a homestead exemption and paid all ad valorem taxes for thirty or more years. The exemption is unconditional in the text once the eligibility criteria are met, so assessors will need to verify continuous claim and payment histories before removing property from the tax rolls.
Removes the phased‑in treatment for large homestead assessment jumps
The amendment repeals the existing constitutional paragraph that provided for phase‑in of additional property tax liability when a homestead’s assessed valuation increased by more than a fixed percentage (historically, 50%). Removing this paragraph eliminates that constitutional smoothing mechanism and interacts with the new CPI cap in ways that require careful administrative interpretation.
Applies to tax years beginning on or after January 1, 2027
The amendment becomes effective January 1, 2027 and governs ad valorem tax years that begin on or after that date. That timing gives assessors and taxing authorities a single start date for applying the CPI cap, the reappraisal interval change, and the eligibility lookback for the 30‑year exemption.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Long‑term homestead owners who have continuously held the homestead and paid taxes for 30+ years: they gain a permanent exemption from future ad valorem taxation once they meet the conditions, potentially eliminating property tax liability on that property.
- Current homestead owners on fixed incomes: capping assessed‑value increases to CPI‑U limits year‑to‑year tax exposure tied to market spikes and creates predictable, inflation‑linked growth in assessed value.
- Homeowners who defer major renovations: because the CPI cap excludes increases from construction, owners who avoid or postpone improvements preserve the benefit of the cap against market appreciation.
- Estate planners and owners of long‑held properties: the 30‑year rule creates a defined threshold that can be incorporated into long‑term ownership and estate planning strategies.
Who Bears the Cost
- Parishes, school districts, and other local taxing entities: slower growth in assessed values and a pathway to permanent local tax exemptions reduce the growth of the taxable base and could force spending cuts, millage increases, or state aid requests.
- Parish assessors and tax collectors: they must implement the CPI cap, exclude improvement‑driven value increases, verify 30‑year homestead and tax‑payment histories, and adjust reappraisal scheduling—adding recordkeeping, enforcement and auditing burdens.
- New homeowners and recent buyers: tax liabilities for newcomers may rise relative to long‑term owners as tax shifts concentrate on properties not yet qualified for the 30‑year exemption.
- Local fiscal planners and bondholders: reduced, less‑predictable ad valorem growth complicates revenue forecasting that underpins budgeting and debt service calculations.
Key Issues
The Core Tension
The bill pits two legitimate public goals against each other: protecting long‑time, often lower‑income homeowners from rapid tax increases and preserving stable local government revenue. Any mechanism that limits assessed‑value growth or creates permanent exemptions reduces the taxable base, forcing local governments either to cut services, raise rates on other taxpayers, or seek state assistance—so the trade‑off is between taxpayer stability and local fiscal capacity.
The amendment intertwines several moving parts that raise implementation and equity questions. First, tying assessed‑value growth to CPI‑U creates a clear rule but also links property tax growth to a national inflation measure that may not correlate with local real‑estate appreciation; in rapidly appreciating markets the cap will understate value growth, while in deflationary periods it could freeze assessed values.
Assessors will need robust protocols to separate appreciation from improvement‑driven value—an evidentiary and administrative task that will invite disputes and appeals.
Second, the 30‑year exemption is simple in principle but complex in practice. The constitutional language conditions the exemption on an owner’s history of claiming homestead status and paying all ad valorem taxes for thirty or more years.
That raises questions about continuity (must it be continuous?), treatment after ownership transfers, whether heirs or trusts qualify, and how to treat years with tax refunds, abatement, or successful appeals. These verification tasks will fall on parish offices with varying record systems.
Finally, the combination of a longer reappraisal interval and the CPI cap reduces the frequency and magnitude of taxable base adjustments; while this stabilizes taxes for many homeowners, it accelerates the fiscal tradeoff between taxpayer protections and the revenue needs of local services—especially education, which is heavily funded by property taxes in many parishes.
