📢 Legislative Session 2026 Update from Assessor Tab Troxler:

Senate Bill 88, authored by Senator Greg Miller, proposes a potential increase to the Homestead Exemption that could have a significant impact for homeowners in St. Charles Parish. If approved, this constitutional amendment would allow the Parish Council to increase the Homestead Exemption from the current $7,500 assessed value to as much as $22,500.

What does that mean for you?
👉 Potential annual property tax savings could increase from around $750 to more than $2,250 for primary residences. This measure must first receive a two-thirds vote in both the House and Senate and be signed by the governor. If that occurs, it will then appear on the November 2026 statewide ballot for voters to decide.

As always, we will continue to keep residents informed on legislative changes that may affect property taxes in St. Charles Parish. Please see the links in the comments for more information.

Got questions about assessments in St. Charles Parish?

Our Frequently Asked Questions are designed to walk homeowners through reassessment, homestead exemption, millage rates, and how property taxes are calculated in plain language.

We’ve just added a new FAQ explaining why homes valued close to $75,000 can see a noticeable tax bill change even when the value increase seems small.

Visit the FAQ section on our website to learn more and get clear answers. 👇

A mill is one-tenth of a cent, or $1 in taxes for every $1,000 of assessed value. For 2025, St. Charles Parish had a total Taxable Assessed Value of $2,567,923,345. That means 1 mill generates approximately $2,567,923 in property taxes parishwide.

So when millage rates are discussed at public meetings, this helps show the real-world impact:
• ½ mill ≈ $1.28 million
• 2 mills ≈ $5.13 million
• 5 mills ≈ $12.84 million

Millage rates are set by individual taxing bodies (Parish Government, School Board, Sheriff, etc.), not by the assessor’s office. Our role is to determine fair market value and maintain the tax roll, the official list of all taxable property.

FOR HOMEOWNERS: Homestead exemption renewal cards have been sent for 2026. Be sure to complete, sign, and mail back the bottom portion. This ensures a deduction $75,000 of the fair market value of your primary residence, which provides savings on your annual property tax bill. For more information, see the link in the comments.

Homestead Exemption Card Delay Notice 📬

Homestead Exemption cards will be mailed later than usual this year. The delay is due to a Jan. 28 meeting of the Louisiana Tax Commission, where members will vote on whether to approve a cost-of-living increase to the income limit for age 65+ assessment freeze eligibility.

This will not affect your ability to apply or re-certify for a homestead exemption. We are waiting to include the updated information on the card, as this is one of only two times per non-reassessment calendar year the assessor's office sends mass mailers. Cards will go to print shortly after the income limit has been set.

We appreciate your patience. As always, we’re here to help with any questions. Visit our website for eligibility info and more.

Start the New Year right! Make sure you’re receiving every property tax break you’re eligible for. 📅

If you’re a senior, a disabled homeowner or veteran, or a first responder, you may qualify for a special assessment level (commonly called a “freeze”) or an additional homestead exemption. These programs can help stabilize your property taxes, but you have to apply.
