Reassessment 2024
Reassessment of residential properties happens every four years.
This means the St. Charles Parish Assessor’s Office will be valuing all properties in the parish that are subject to property taxes as mandated by the Louisiana Constitution and state law.*
The St. Charles Parish Assessor’s Office is dedicated to completing a fair, consistent, and transparent reassessment process based on the most accurate data available. This page is meant to help you understand all the factors that go into finding your residential property’s fair market value and how that value relates to property taxes, or millages.
The assessor values properties, while local taxing districts and governmental agencies set millage rates. Those rates are subject to authorization by you, the voter, usually for a period of 10 or more years.
Assessor Tab Troxler and the staff of the St. Charles Parish Assessor’s Office are here to serve you. Should you have any questions or concerns, or just want more information, don’t hesitate to contact the office.
*The Louisiana Constitution of 1974, Article VII Section 18(f) mandates reassessment every four years.

About Assessments & Property Taxes
The assessor is responsible for discovery, listing, and valuing all property in the parish for ad valorem tax purposes. The assessor is also responsible to the citizens to ensure all property is assessed in a fair and equitable manner. Your property’s assessment is used to calculate the amount of property taxes you will owe each year.
For example, if your home is valued at $175,000 and assessed at 10%, or $17,500, and you are eligible and have signed for homestead exemption, you would calculate your taxes as follows.
Home’s Assessment (Fair Market Value): $175,000
Homestead Exemption (Subtract $75,000): $100,000 Taxable Fair Market Value
Millage Rate Applies to 10% of the Taxable Fair Market Value: $10,000 Taxable Assessed Value
Multiplied by the Millage Rate: 10,000 x 0.11164 = $1,116.40 Tax Bill
The example above uses the 2023 West Bank Millage Rate of 111.64
How the Assessor Determines Residential Fair Market Value
SALES OCCUR: Sales occur during the reassessment period.
VALUES DEVELOPED AND MODELS APPLIED: Assessors nationwide use Mass Appraisal techniques to value properties for tax purposes. Mass appraisal differs from individual property appraisal in significant ways. Our appraisal methods are required to use actual sales filed in the St. Charles Parish Clerk of Court’s Office. Concessions/financing irregularities are adjusted within the valuation model. We utilize a large database of sales with varying property characteristics to develop an appropriate valuation model to determine the market value of all properties. Statistical software uses Multiple Regression Analysis (MRA) to derive adjustments.
CHANGES REVIEWED: Office staff undertakes a detailed review of the changes generated by the computer models.
DETERMINATION MADE: The assessor determines the final assessment.
NOTIFICATIONS SENT: Notifications are sent to the property owner of the new value. The change will be reflected on the same year’s tax bill.
Options for Homeowners
The assessor sets assessed values on homes in St. Charles Parish, but his office does not control the property tax rates of various local taxing bodies. Below is more information about the ways residents can reduce their tax burdens.
APPLY FOR HOMESTEAD EXEMPTION: This exempts the first $75,000 of market value on a primary residence. In St. Charles Parish, this is equivalent to about $835 in annual property tax savings. [MORE INFO]
PARTICIPATE IN ELECTIONS: Millage rates are subject to voter approval. [MORE INFO]
MONITOR STATE LEGISLATION: State laws have a large effect on how property taxes are administered. [MORE INFO]
TAKE ADVANTAGE OF ASSESSMENT FREEZES OR SPECIAL LEVELS: Homeowners 65 or older, those who are disabled, disabled veterans, first responders, or surviving spouses of active-duty first responders killed on duty may be eligible for assessment freezes or an additional homestead exemption. [MORE INFO]
ATTEND A PUBLIC MEETING: Taxing bodies set their annual millage rates at advertised meetings.
