The Louisiana Tax Commission is the state agency that keeps property assessments fair and uniform across all 64 parishes. It reviews every local assessor’s work, directly appraises public service property such as utilities, railroads, and pipelines, hears taxpayer appeals from local Board of Review decisions, and can order a parish to reappraise property when valuations drift too far from constitutional standards. Several laws taking effect in 2026 also expand its reporting and dispute-review responsibilities.
What the Commission Oversees
Local assessors do the ground-level valuation work. The commission is the quality-control layer sitting above them. Each year, assessors submit their assessment rolls to the LTC, which reviews them against the constitutional rule that property be assessed at a set percentage of fair market value: 10 percent for residential property and 15 percent for most commercial and industrial property under Article VII, Section 18 of the Louisiana Constitution.
The commission writes the guidelines assessors follow, issues advisory opinions, runs training sessions, and sets the quadrennial reappraisal schedule. Louisiana law requires real property to be reappraised at least every four years using the valuation date and procedures the commission establishes.1Legal Information Institute (LII) / Cornell Law School. La Admin Code Tit 61, V-121 – Reappraisal That cycle keeps valuations tied to actual market conditions so a stale number doesn’t quietly inflate or deflate a tax bill.
Between reappraisal years, the commission still monitors whether assessors are applying market data consistently. The point is cross-parish fairness. A commercial building in Caddo and a comparable one in East Baton Rouge should be assessed under the same standards even though different people are doing the valuing. For specialized property, including oil and gas equipment, agricultural land, and timberland, the LTC publishes additional rules that fit the economics of those assets.
Public Service Property Appraisal
One of the commission’s most distinctive jobs is appraising public service property itself rather than leaving it to local assessors. Utilities, railroads, pipelines, and similar companies file annual reports, and the LTC uses those reports and any other available data to set a value on or before September 1 each year.2Justia. Louisiana Revised Statutes Title 47 RS 47-1853 – Appraisal of Public Service Properties
The commission applies three recognized methods, the market approach, the cost approach, and the income approach, giving each whatever weight best reflects fair market value for the property at hand. Once the total value is set, land is separated out and listed as a distinct item on the tax roll. Non-operating or non-utility property owned by a public service company is assessed locally like any other property in the parish.2Justia. Louisiana Revised Statutes Title 47 RS 47-1853 – Appraisal of Public Service Properties
How It Enforces Compliance With Local Assessors
Under R.S. 47:1837, the commission measures appraisal and assessment levels in every parish and publishes the results each year. That measurement counts as prima facie evidence of whether a parish meets constitutional requirements. When a parish’s level deviates by more than 10 percent from the required percentage of fair market value, the commission can order the assessor to reappraise all property, or specific classifications of property, within one year.3Justia. Louisiana Revised Statutes Title 47 RS 47-1837 – Duties and Responsibilities
Before issuing a reappraisal order, the commission holds a public hearing to receive complaints. The assessor and every tax recipient body in the affected parish or district get written notice. The commission then certifies the current year’s assessment lists and measures the parish again the next year to confirm compliance.
Appealing a Property Assessment to the Commission
If you believe your assessment is wrong, you reach the Tax Commission only after working through earlier stages. Each stage has a firm deadline, and missing one can forfeit your right to contest.
Getting to the Commission
Your first opportunity to challenge an assessment is the open inspection period, when the assessor opens tax lists to the public, usually between July 15 and August 15. You can raise concerns informally with the assessor’s office during that window. If that doesn’t resolve things, you file a formal appeal with the assessor for review by the local Board of Review. The filing deadline falls within a few business days after the inspection period closes, so check with your parish assessor for the exact date. The Board of Review typically holds hearings in September and early October.
If the Board of Review rules against you, you have 10 business days after the notice of determination is delivered to file a written appeal with the Louisiana Tax Commission.4New Orleans City Council. Property Tax Assessments and Appeals Information That deadline is strict. The commission then reviews the evidence from both sides in a formal hearing. Both parties get at least 60 days’ notice before the hearing, and at least 30 days’ notice if a hearing is rescheduled.5Legal Information Institute (LII) / Cornell Law School. La Admin Code Tit 61, V-3103 – Appeals to the Louisiana Tax Commission
What Evidence You Can Present
At the LTC level, the range of admissible evidence is broader than many taxpayers assume. The commission may consider publicly available data including aerial photography, public conveyance records, building permits, multiple listing service sales data, and published cost guides.6Justia. Louisiana Revised Statutes Title 47 RS 47-1989 – Review of Appeals by Tax Commission An independent appraisal can usually be submitted even if it wasn’t part of your Board of Review file, as long as you give it to the assessor within 30 days of receiving it and at least 25 days before the LTC hearing.
Financial documents, depreciation schedules, and environmental assessments that weren’t available at the original filing deadline also get leeway, provided you share them with the assessor within 15 days of their becoming available.6Justia. Louisiana Revised Statutes Title 47 RS 47-1989 – Review of Appeals by Tax Commission The commission can also independently appraise the real property during the review and enter that appraisal into evidence.
Paying Under Protest While You Appeal
Your tax bill does not pause while the appeal is pending. If you want any chance of a refund after winning, you have to pay the disputed amount under protest using the correct procedure. Louisiana law requires separate payments: one for the portion of the tax you don’t dispute, and a separate payment for the contested amount, clearly designated as a protest payment.7Justia. Louisiana Revised Statutes Title 47 RS 47-2134 – Suits to Recover Statutory Impositions Paid Under Protest
You also have to notify the collecting officer that the payment is tied to a correctness challenge. The officer holds the protested amount in a segregated escrow account. Win the appeal, and the collector refunds the protested amount with the interest earned in escrow. Pay without following the protest procedure, and getting money back later is far harder even if the assessment is reduced.7Justia.

Public Access to Commission Meetings and Records
Louisiana’s open meetings law applies to the Tax Commission, and because it is a nonelected body with authority connected to tax levies, it is required to record or broadcast its public meetings.8Louisiana Legislative Auditor. Course 103 – Open Meetings and Public Records Proceedings outside executive session may be recorded, filmed, or broadcast live. Written minutes must be kept, and if the commission posts them to a website, they go up within 10 days of publication in the official journal and stay available for at least three months.
Anyone 18 or older can inspect or copy public records, including minutes and hearing transcripts. If the record is on hand, the custodian must allow immediate examination; if it’s in use or not immediately available, the custodian has three business days to produce it.8Louisiana Legislative Auditor. Course 103 – Open Meetings and Public Records
What’s Changing for 2026
Several recent laws reshape the commission’s work starting in 2026.
Tax Lien Auctions Replace Tax Sales
Act 774 of 2024 overhauls how Louisiana handles delinquent property taxes. The old system of tax sales and adjudication, under which a political subdivision could take title to property with unpaid taxes, ended on December 31, 2025. From January 1, 2026 onward, delinquent tax obligations are auctioned as liens rather than property titles, and statutory terms like “acquiring person” and “adjudicated property” now apply only to transactions that occurred before January 2026.9Louisiana State Legislature. RS 47-2122 – Definitions The LTC continues to review disputes arising from the transition, including objections tied to tax postponements during public calamities.
Business Inventory Reporting
Act 357 of 2025 lets a parish’s sheriff, school board, and governing authority agree to assess business inventory below the 15 percent constitutional default. Any such agreement must be put in writing and sent to the Louisiana Tax Commission and the local tax assessor within 10 calendar days of execution. The commission must then include every notification it receives in its annual reports.
Homestead Special Assessment Level
Beginning with the 2026 tax year, the $100,000 income cap for the special assessment level freeze adjusts annually by the Consumer Price Index, and homeowners aged 65 or older who receive the homestead exemption are no longer subject to the income limitation at all.10Louisiana Legislature. Redesignations of Law – Homestead Exemption A retiree with income above $100,000 can now lock in the special assessment level if they meet the age requirement. A separate 2026 proposal would let individual parishes authorize a homestead exemption higher than $7,500 of assessed value starting in tax year 2027, but that change depends on voter approval of a constitutional amendment.
