Lafayette Parish Tax Assessor Justin Centanni joins Discover Lafayette to explain the duties of his office, how property values are determined, and what property owners need to know about the upcoming 15-day assessment review period.
Justin is Lafayette Parish’s 26th Tax Assessor, but his professional path to the office was anything but traditional. With a background in technology and data management, he previously worked in Washington, D.C., for the Department of Defense, helping develop software behind the military’s smart identification cards. He later worked at IberiaBank, where he managed a team responsible for backend data integration, including platforms used to detect fraud and illicit banking activity in real time. Before becoming assessor, Justin served nine years as the District 6 representative on the Lafayette Parish School Board.
Justin says public service was never something he envisioned for himself. He moved to Lafayette at 18 to attend USL and ultimately found that serving the community gave him an unexpected sense of purpose.
“What I learned about myself and public service is that I do take a tremendous amount of personal satisfaction from helping solve problems, helping make decisions. I care a tremendous amount about Lafayette.”
What Does the Tax Assessor Actually Do?
One of the biggest misconceptions about the assessor’s office is that it collects property taxes. It does not. The assessor’s responsibility is to identify and value all property in Lafayette Parish.
That seemingly simple mission involves an enormous amount of information.
The office begins each year with the previous year’s tax roll and continually updates it with information from municipalities, the Clerk of Court and other sources. Building permits reveal new construction and renovations. Conveyance records identify properties that have been sold or transferred. Appraisers visit properties where construction has been completed and determine when values need to be updated.
And Lafayette gives them plenty to keep up with.
Justin says approximately 15,000 properties transfer each year, including residential and commercial property, and more than 1,000 new buildings were constructed in the parish during the past year. Lafayette Parish currently has an approximately $3.3 billion assessed-value tax roll, representing a little more than $30 billion in market value.
As Justin put it, those numbers tell an encouraging story about Lafayette’s economy. He jokingly offered one particularly visible example: “We’re building an $80 million gas station at Louisiana Avenue,” referring, of course, to Buc-ee’s.
How Your Property Value Is Determined
For homeowners who have not substantially changed their property, assessments generally move according to what comparable homes in the neighborhood are selling for.
The assessor’s office examines neighborhood sales and establishes a price per square foot. Larger homes will therefore have a higher value than smaller homes, but comparable properties within the neighborhood are valued using a consistent methodology.
Parishwide reassessments occur every four years. The last reassessment was in 2024, and the next will take place in 2028.
Of course, Justin understands the eternal property owner’s dilemma: everybody wants a high appraisal when they are selling or refinancing their home and a low valuation when the property tax bill arrives. “Don’t we all,” he laughed. “I’m no different.”
August 17 Through 31, 2026: Assessment Review Period
An important focus of our conversation was Lafayette Parish’s 2026 Assessment Review Period, August 17 through August 31.
Property owners whose assessments increased by 15 percent or more should have received notice from the assessor’s office. But the review period is also an important opportunity for anyone who believes the assessor’s office has incorrect information about their property.
Justin explained that the most common type of error might be something as straightforward as incorrect square footage. If the assessor’s records show a 6,000-square-foot home when the home is actually 4,000 square feet, that error can significantly affect the tax bill.
“If we have the square footage of your house incorrect…you should come in and you should tell us,” Justin said. The assessor’s office can measure the property, correct its records and adjust the valuation accordingly.
This first step is important. A taxpayer who wants to challenge an assessment must first meet with the assessor’s office. The taxpayer and assessor attempt to reach agreement on the property’s proper assessed value. Evidence matters, and simply disagreeing with the valuation does not guarantee that it will be changed.
If an agreement cannot be reached, the taxpayer can proceed to the next level of appeal before the Lafayette Parish Council, sitting as the Board of Review. But to preserve that right, Justin explained that the taxpayer must first have an in-person meeting with the assessor’s office during the review period.
Appointments can be made through the Lafayette Parish Assessor’s website, https://lafayetteassessor.com/, and taxpayers can request the appropriate specialist depending upon whether their issue involves an appraisal, personal property, a property transfer or another matter. They may be contacted by phone at (337) 291-7080.
Senior Freezes, Veterans and Homestead Exemptions
The assessor’s office interacts frequently with senior citizens, veterans, real estate professionals and families dealing with inherited property.
Justin explained that qualifying homeowners over age 65 may obtain a special assessment level, commonly called the “senior freeze.” For 2026, he said the income threshold is less than $102,000 in adjusted gross income.
An important distinction: the senior freeze freezes the property’s assessed value, not the amount of taxes owed. Millage rates can still affect the ultimate tax bill. Justin also explained that once a taxpayer qualifies, the income qualification does not have to be revalidated annually.
Veterans may also qualify for special property tax exemptions, and the office regularly assists families after the death of a property owner.
Justin shared that the office monitors obituaries and other data sources so ownership and homestead exemption records can be kept current. He also spoke candidly about the sensitivity required when contacting families shortly after a death.
“We’re trying to interpret the law in the most compassionate way possible,” he said, while acknowledging that the office still has a legal duty to maintain accurate records.
A Warning for Estate Planning Attorneys: Trusts and Homestead Exemptions
Our conversation also ventured into an issue especially important for Louisiana attorneys and their clients: transferring a primary residence into a trust.
Justin explained that a trust must be structured properly if the homeowner intends to retain the homestead exemption. Losing that exemption can have a cascading effect because special assessment levels, including a senior freeze, depend upon the existence of the homestead exemption.
If a longtime homeowner inadvertently loses both the homestead exemption and senior freeze, the consequences can be substantial. Justin gave the example of a home whose value had been frozen since the 1990s suddenly having to be reassessed at its 2026 value.
His office would much rather catch the problem before that happens.
“We try to catch them and say, ‘Go back and redo this so that we don’t have to do this to your client, because I don’t think that’s what the client was looking to do.’”
Justin encourages attorneys who have questions about how estate planning transactions may affect property tax exemptions to contact the assessor’s office.
The Mystery of Properties Nobody Can Find
One of the most fascinating parts of our conversation involved something Justin never expected to encounter as assessor: properties on the tax roll that his office cannot definitively locate.
Some parcels date back more than a century, when property descriptions might reference a road, a neighboring landowner or hand-drawn boundaries rather than today’s precise legal descriptions.
Justin described one document dating to 1905 that identified surrounding tracts essentially by references to other family members’ property, with no modern landmarks to pinpoint its location. Nevertheless, the property made it onto the tax roll, and someone continued paying the taxes for generations.
“I never in a million years thought there would be property we didn’t know where it was,” Justin said.
The problem becomes especially complicated when property has passed through generations without a succession and may now have a multitude of co-owners. Some rural timberland parcels generate only a tiny annual tax bill, so one family member may simply continue paying it year after year.
Bringing the Assessor’s Office to the Public
Justin is also looking for ways to make his office more accessible.
The assessor’s office is located at 213 West Vermilion Street in downtown Lafayette, in the former Capital One/Hub City Bank building. But Justin heard repeatedly from residents outside the city that driving downtown, finding parking and visiting the office could be inconvenient.
That led to the creation of Parish Pop-Ups, where assessor’s office employees spend time in municipalities around Lafayette Parish helping residents with assessments, senior freezes and other property matters.
One woman arrived at a recent pop-up before the staff had even officially begun for the day. She had been putting off applying for her senior freeze for years simply because she didn’t want to make the trip downtown. She arrived with her paperwork ready and was able to take care of it.
For Justin, that is exactly the point.
“We are really just trying to figure out ways that we can better serve the public and make it easier for them to interact with our office.”
Where Do Your Property Taxes Actually Go?
We also discussed something every property owner wonders about when that tax bill arrives: Where does the money go?
Individual millages are levied for particular taxing bodies and, in many cases, dedicated to specific purposes. School Board millages support schools. Other millages support entities and services such as law enforcement, the health unit, mosquito control, the airport, libraries and municipal services.
The assessor determines the taxable value, but the assessor does not decide the tax rate or determine how those tax dollars are spent. Those decisions belong to the respective governmental and taxing authorities.
The assessor’s website publishes annual “grand recaps,” reports required by the Louisiana Tax Commission that allow the public to see how much revenue is generated by the various millages throughout Lafayette Parish and its municipalities.

Even Parish Lines Can Be Complicated
Justin shared one final surprise that came with the job: disputes over exactly where Lafayette Parish ends and a neighboring parish begins.
Some parish boundaries were historically defined by bayous and waterways, and those waterways may have shifted since the boundaries were established nearly two centuries ago.
“My constitutional duty is to assess all property in my parish,” Justin explained. That means the assessor sometimes has to determine whether a particular piece of land actually sits in Lafayette Parish, even when another parish assessor may reach a different conclusion.
As Justin joked about relying on modern technology to solve an old Louisiana boundary dispute, “Siri has an opinion, just like everybody else. Unfortunately, there’s only 64 opinions that actually matter in this situation.”
When Justin isn’t immersed in property values, data and parish boundaries, he is a voracious reader who enjoys spy novels and estimates he reads 30 to 35 books each year. His mornings typically begin with coffee, number puzzles and crossword puzzles, and when fall arrives, plenty of football enters the mix.
