I'm planning a $40,000 addition to my Louisiana $250,000 home. Will I lose the Special Assessment Level?

$40,000 on $250,000 is a 16% increase — under the 25% threshold. The freeze stays intact for the original portion of the home; the $40,000 of new construction value is assessed and added on top of the frozen base. If the addition pushed total increase above 25% (e.g., a $70,000 addition on a $250,000 home = 28%), the freeze terminates entirely and the property reassesses at full current value. Run the math before committing to a project; consult your parish assessor on borderline cases.

My Louisiana parish raised millage rates — why did my tax bill go up despite the senior freeze?

The Special Assessment Level freezes the assessed value, not the tax bill itself. If your parish raised millage rates, the higher rate is multiplied against your locked assessed value — producing a higher tax bill even though the assessment is frozen. The freeze prevents assessment from rising; it doesn't prevent rate increases from flowing through. This is structurally different from rate-and-assessment freezes some other states offer (e.g., Connecticut's older §12-129b legacy freeze, which froze the bill itself). Louisiana's mechanism is purely on the assessment side.

Louisiana Special Assessment Level: The $75,000 Homestead Exemption Plus the Senior Assessment Freeze (Income Cap CPI-Indexed Past $100,000)

Q: My Louisiana AGI is $105,000 — am I above the Special Assessment Level cap?

Likely yes. The Amendment 6 (2020) base was $100,000 with annual CPI indexing; some parishes report the 2026 figure as $102,700. At $105,000 you're above even the indexed cap. The income test uses adjusted gross income from your federal return — not gross income — so deductions taken on your 1040 do reduce the figure used here. Income drops below the threshold in a future year would open eligibility.

Updated April 2026

Louisiana stacks two layers of property tax relief for qualifying seniors. The universal Homestead Exemption shields the first $75,000 of a home's value from property tax for any owner-occupant — not senior-specific. Layered on top, the Special Assessment Level (often called the “senior freeze” in Louisiana) freezes the assessed value of the homestead at the level it was when the senior first qualified, preventing reassessment-driven tax increases. The Special Assessment Level requires age 65+ (or disabled veteran 50%+, or court-determined totally disabled) plus an income test that, after Amendment 6 of 2020 and subsequent CPI indexing, stands above $100,000 for 2026 (some parishes report the indexed figure as $102,700).

The Universal $75,000 Homestead Exemption

Available to any Louisiana owner-occupant of a primary residence. Shields $75,000 of value from property tax — Louisiana's constitutional homestead exemption. Not senior-specific; applies regardless of age or income. File once with the parish assessor; auto-renews. The base exemption is the foundation that the senior-specific Special Assessment Level layers on top of.

The Special Assessment Level (Senior Freeze)

Three eligibility paths:

Age 65 or older, OR
Disabled veteran with a service-connected disability rating of 50% or greater, OR
Permanently and totally disabled as determined by a court or federal agency.

Plus an income test: adjusted gross income cannot exceed $100,000 (CPI-indexed annually under Amendment 6 of 2020; some parishes report the 2026 figure as $102,700 reflecting CPI adjustment).

Once qualified, the Special Assessment Level permanently locks the assessed value of the homestead at the level it was when the freeze took effect. Property tax owed stays flat (relative to the underlying assessment) as long as: the homeowner continues to own and occupy the home, and the value doesn't increase by more than 25% due to construction or reconstruction. Note that the freeze is on assessment, not on the tax bill — a parish millage rate increase still flows through to the bill, but the assessment piece is locked.

Is your Louisiana parish assessment defensible?

The Special Assessment Level locks the assessed value at qualification — if assessment was inflated when you qualified, you locked in too high a base. An assessment review before applying for the freeze ensures the locked figure is correct.

The 25% Construction Exception

Louisiana's freeze has a unique carve-out: the locked assessment terminates if the property value increases by more than 25% due to construction or reconstruction. So adding a small addition that increases value by 15% leaves the freeze intact (the addition is added on top of the frozen base); building a major addition or extensively renovating that pushes total value above 25% growth ends the freeze entirely and the property is reassessed at full current value.

The 25% threshold is significantly more restrictive than freeze-breakage rules in some other states. A senior considering substantial renovations should run the math: a project that pushes assessed value past the 25% threshold loses the freeze permanently, not just for the affected portion.

Application Through the Parish Assessor

File with your parish assessor (Louisiana's 64 parishes serve the role counties play in most states). Required documentation:

Government photo ID confirming age (for senior path).
VA disability rating documentation (for disabled veteran path) — 50% or greater service-connected.
Court order or federal agency determination (for total disability path).
Proof of property ownership and primary residence status.
Most recent federal tax return showing AGI for the income test.

Once granted, the Special Assessment Level remains in place permanently as long as eligibility persists. No annual reapplication. But the parish assessor periodically requests updated income documentation to verify the income test still holds; respond promptly to those requests to keep the freeze active.

Frequently Asked Questions

My income is $105,000. Am I above the cap?

Likely — but check with your specific parish. The Amendment 6 (2020) base was $100,000 with annual CPI indexing, and some parishes report the current 2026 figure as $102,700. At $105,000 you're likely above even the indexed cap. Income drops below the threshold in a future year would open eligibility. The income test uses adjusted gross income from your federal return, not gross income — so deductions taken on your 1040 reduce the figure used here.

I'm planning a $40,000 addition to my $250,000 home. Will I lose my Special Assessment Level?

$40,000 on a $250,000 home is a 16% increase — under the 25% threshold. The freeze stays intact for the original portion of the home; the $40,000 of new construction value is assessed and added on top of the frozen base, but the locked figure for the existing structure remains. If the addition pushed total value increase above 25% (for example, a $70,000 addition on a $250,000 home = 28% increase), the freeze terminates entirely and the property reassesses at full current value. Run the math before committing to a project; consult your parish assessor on borderline cases.

My parish raised millage rates last year. Why did my tax bill go up despite the freeze?

The Special Assessment Level freezes the assessed value, not the tax bill itself. If your parish raised millage rates, the higher rate is multiplied against your locked assessed value — producing a higher tax bill even though the assessment is frozen. The freeze prevents the assessment from rising; it doesn't prevent rate increases from flowing through. This is structurally different from rate-and-assessment freezes some other states offer (e.g., the older Connecticut §12-129b legacy freeze, which froze the bill itself). Louisiana's mechanism is purely on the assessment side.

Does the freeze transfer when I sell my home?

No. The Special Assessment Level attaches to the specific property and the qualifying owner-occupant. When you sell, the freeze ends; the new buyer reassesses at current market value. If you buy a new home in Louisiana and qualify under the senior/disabled criteria with income under the cap, you can apply for a fresh freeze on the new home — the freeze locks at the new home's current assessment, not at your prior frozen amount.
