📢 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.

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.
