How Property Tax Works

Ouachita Parish (County) property taxes are the primary funding source for essential local services including public schools, law enforcement, fire protection, road maintenance, and parish government operations. The parish uses an assessed value system where properties are typically assessed at 10% of fair market value for residential properties, with various tax credits and exemptions available to qualifying property owners.

Property tax rates in Ouachita Parish vary significantly by location due to numerous special taxing districts including school districts, fire protection districts, drainage districts, and municipal taxes. The effective tax rate generally ranges from approximately 0.8% to 1.2% of assessed value, though this can be higher in areas with multiple special assessments. Property owners should note that most tax credits and exemptions require annual application and are not automatically applied to your tax bill.

Supplemental Tax Bills

Supplemental taxes in Ouachita Parish are additional tax assessments triggered by changes in property ownership, new construction, or significant improvements made after the January 1 assessment date. When you purchase property or complete construction, the parish assessor determines if the change in value warrants a supplemental assessment for the remainder of the current tax year.

For example, if you purchase a home in June that was previously assessed at $150,000 but sells for $300,000, the assessor may issue a supplemental tax bill based on the increased assessed value for the remaining months of the tax year. The supplemental tax is calculated by determining the difference between the old and new assessed values, applying the current millage rate, and prorating for the remaining portion of the tax year.

Escrow & Property Taxes

Most mortgage lenders in Ouachita Parish require property tax escrow accounts to ensure timely payment of property taxes. Your monthly mortgage payment includes a portion that goes into an escrow account, from which your lender pays property taxes when due. Lenders typically collect 1/12th of your annual tax bill each month, plus a small cushion amount as allowed by federal regulations.

Property taxes in Ouachita Parish are typically due in two installments: April 15 and September 15. Your lender will receive tax bills directly from the parish and make payments from your escrow account. You should receive an annual escrow analysis from your lender showing account activity and any required payment adjustments. If your taxes increase due to reassessment or new special districts, your monthly escrow payment may increase accordingly. Property owners are encouraged to verify that payments are made timely and contact their lender immediately if there are any discrepancies.
