How Much Can Property Taxes Increase in Louisiana? 2026 Complete Guide
Updated July 2026
Quick Answer
Louisiana puts no cap on how much your assessed value can rise. Its protection works on the rate side instead: after each reassessment, taxing bodies must roll their millage rates back so they collect the same total revenue as before. They can roll millages back up, to the prior authorized maximum, only after a public hearing and a two-thirds vote of the taxing authority, and any new or higher-than-authorized millage requires voter approval. Residential property is assessed at 10% of fair market value, the homestead exemption shields $7,500 of assessed value ($75,000 of market value) from parish taxes, and qualifying homeowners 65 and older under an income limit of about $100,000 can freeze their assessed value entirely.
Most homeowners never challenge their assessment, usually because nobody tells them they can or shows them how. That gap is the whole reason AppealDesk exists: see what your county has your home on record at, free, and if the number looks wrong we build the case for $49.
Does Louisiana Have Property Tax, and How Much Is It?
Yes. Every parish levies property tax, and so do many cities, school boards, sheriffs, and special districts. What makes Louisiana unusual is the assessment ratio. Under Article VII of the Louisiana Constitution, residential property is assessed at just 10% of its fair market value, so your tax is not computed on what your home is worth but on one tenth of that.
The arithmetic runs like this. A home with a fair market value of $300,000 carries an assessed value of $30,000. If it is your primary residence, the homestead exemption removes $7,500 of assessed value, the equivalent of $75,000 in market value, from parish-level taxes, leaving $22,500 taxable. Multiply that by your combined millage rate to get the bill. If the millages where you live add up to 100 mills, meaning $100 of tax per $1,000 of taxable assessed value, the parish portion on that home would be $2,250. Actual millages vary widely by parish and district, so check your tax notice or your parish assessor for the rates that apply to you.
One detail homeowners often miss: the homestead exemption applies to parish-level taxes but not to municipal property taxes. If you live inside a city that levies its own millage, that city portion is generally computed on the full assessed value with no $7,500 reduction.
Louisiana Millage Rates in 2026: Rollback and Roll-Forward
A millage rate is the tax rate expressed in thousandths: one mill equals $1 of tax per $1,000 of taxable assessed value. Your total rate is the sum of every millage levied where you live, which is why bills differ so much between a rural parish and the city of New Orleans, where Orleans Parish runs its own assessment calendar and municipal millages stack on top of parish ones. Parish-to-parish variation is the rule here, not the exception.
Here is the part of Louisiana law that actually limits your bill, and the part most guides get wrong. When a reassessment raises total assessed values in a district, the constitution requires each taxing authority to roll its millage rates back so it collects the same revenue it collected before. Reassessment by itself is not supposed to be a windfall for local government. The taxing body may then roll the millage forward, back up to its previously authorized maximum, but only after a public hearing and a two-thirds vote of the authority itself. No public election is needed for that roll-forward. Voter approval is required only for brand new millages or for rates above the authorized maximum. So the common claim that Louisiana property taxes cannot rise without a vote of the people is not accurate. Your bill can rise after reassessment if your local boards vote, in public, to roll millages forward.
How Often Is Property Reassessed in Louisiana?
Louisiana requires reappraisal of all property at least every four years, a schedule known as quadrennial reassessment. The most recent statewide quadrennial revaluation cycle was 2024, setting values for the 2024 through 2027 rolls in most parishes, which puts the next statewide revaluation in 2028.
Because values are trued up to the market only every four years, Louisiana reassessments arrive as a step change rather than a gradual climb. If your neighborhood appreciated meaningfully since the last cycle, the new value can jump all at once, and nothing softens that jump. There is no cap on annual assessment increases in Louisiana. Assessed value tracks fair market value.
How Much Do Property Taxes Go Up Each Year?
In a non-reassessment year, most Louisiana homeowners see little movement, because the assessed value is standing still until the next quadrennial cycle. Bills change in those years mainly when voters approve a new millage, when an existing millage expires or is renewed, or when a taxing body adjusts a rate within its authorized maximum.
In a reassessment year the answer depends on two things: how much your value rose relative to everyone else's, and what your local taxing bodies do with their millages. If your value rose about the same as the parish average and every authority rolled back without rolling forward, your bill should stay roughly flat. If your value rose faster than average, your share of the levy grows even under a full rollback. And if authorities vote to roll forward, the whole base pays more. There is no statutory percentage limit on any of it, which is why the honest answer to how much property taxes can go up in a year in Louisiana is: as much as the market moved your value, minus whatever the rollback mechanism gives back.
Caps and rate limits only control how fast your bill can grow. Nothing in them checks whether the number underneath is right. Assessors in Louisiana set values with mass-appraisal models that price thousands of homes at once, and nobody reviews yours unless you challenge it.

Are Property Taxes Going Up in Louisiana in 2026?
For most parishes, 2026 sits inside the 2024 to 2027 roll period, so values themselves are largely locked until the 2028 revaluation. Whether your 2026 bill rises therefore comes down mostly to rate decisions: roll-forward votes by local taxing bodies, and any new millages approved by voters in your parish. If your taxes went up this year without a reassessment, a millage change is the likely reason, and your tax notice will show the line items that moved.
One thing that did not change the landscape: Amendment 2, the sweeping rewrite of the constitution's tax article that went to voters on March 29, 2025, was rejected. Louisiana's property tax framework, including the 10% residential ratio, the homestead exemption, and the rollback rules described here, remains as it was.
The November 2026 Amendment: Senior Tax Freeze Income Limit Rising to $150,000
Louisiana's strongest individual protection is the special assessment level, a freeze that locks in the assessed value of a homestead for homeowners 65 and older, permanently disabled owners, and certain veterans and surviving spouses. To qualify, household income must fall under a limit that sits at about $100,000 as of 2025 and is indexed annually. For a qualifying homeowner, a quadrennial reassessment simply does not raise the assessed value, whatever the market did.
That income limit may rise. HB 300 from the 2025 legislative session referred a constitutional amendment to the November 3, 2026 ballot that would raise the special assessment level income limit from $100,000 to $150,000. As of this writing it is a pending ballot measure, not law. If voters approve it, Louisiana homeowners who currently earn too much to qualify would become eligible for the freeze. If you are 65 or older, or you qualify as disabled or as a covered veteran or surviving spouse, apply with your parish assessor now if you are under the current limit, and watch the November 2026 result if your income falls between $100,000 and $150,000.
What you can do about it
How to Appeal Your Louisiana Assessment
Because Louisiana has no assessment cap, the appeal is the only check on the value itself, and the window is short and parish-specific. Each year the assessment rolls are open for public inspection for a 15-day period falling somewhere between August 1 and September 15. Your parish assessor publishes the exact dates, and Orleans Parish runs its own schedule. During the open-rolls period you can review the value placed on your home and compare it against what the property would realistically sell for.
If the number is too high, you file a Notice of Appeal Request for Board of Review, Form 3101, with your parish Board of Review, which is typically the parish governing authority. The filing has to happen during or immediately after the open-rolls period, so the practical move is to check your value the day the rolls open rather than waiting for a bill in December, when it is far too late. If the Board of Review does not resolve it, you can appeal to the Louisiana Tax Commission, and from there to the courts. Most homeowner appeals are won or lost at the Board of Review stage on comparable sales evidence.
A real AppealDesk order, Harris County, Texas
In June 2026, a homeowner in Harris County, Texas ran the check. The county had their home on record at $3,148,044, while recorded sales of comparable homes supported about $2,391,577: an over-assessment of $756,467, worth roughly $11,138 per year if corrected. Their packet laid out the comparable sales, the forms, and the filing steps. Nobody at the county was ever going to run that check for them.
Growth limits only help if the number they grow from is fair. If your assessment jumped after a purchase, new construction, or a revaluation, that new number is the one nobody has reviewed. Checking it is free and takes about a minute.

When Are Property Taxes Due in Louisiana?
Louisiana property tax bills are generally mailed in November and due by December 31 of the tax year. Payment goes to your parish tax collector, usually the sheriff's office outside Orleans Parish. If you escrow taxes through your mortgage, your servicer pays from that bill, but it is still worth opening the notice, because the assessed value printed on it is the number your next appeal window will be about.
Frequently Asked Questions
How much can my Louisiana property taxes increase this year?
There is no percentage limit. Assessed value tracks fair market value with no cap, so a reassessment can raise your value by whatever the market moved. The constitutional rollback requirement offsets reassessment gains at the district level, but a two-thirds roll-forward vote by your local taxing bodies, or a voter-approved new millage, can still push your bill up.
What is Louisiana's property tax rate?
There is no single statewide rate. Your rate is the sum of the millages levied by your parish, school board, city, and special districts, applied to 10% of your home's fair market value, minus the $7,500 homestead exemption on parish taxes for a primary residence. Rates vary substantially by parish, so check your tax notice or parish assessor for your combined millage.
How often is my property reassessed in Louisiana?
At least every four years. The most recent statewide quadrennial cycle was 2024, covering the 2024 through 2027 rolls in most parishes, with the next revaluation due in 2028.
Do seniors get a property tax break in Louisiana?
Yes. The special assessment level freezes assessed value for qualifying homeowners 65 and older, permanently disabled owners, and certain veterans and surviving spouses, subject to an income limit of about $100,000 in 2025. A November 3, 2026 ballot measure would raise that limit to $150,000 if voters approve it.
What is the best way to control my property tax increases?
Watch the open-rolls window between August 1 and September 15 and appeal through your parish Board of Review with Form 3101 if the value is too high. Make sure your homestead exemption is on file, apply for the special assessment level if you qualify, and follow roll-forward hearings and millage elections in your parish, since that is where the rate side of your bill gets decided.
