How Property Tax Works

St. Bernard County operates under Louisiana's parish-based property tax system, where property taxes fund essential local services including schools, law enforcement, fire protection, libraries, hospitals, and recreation facilities. The county's effective tax rate is built around Louisiana's base assessment rate of approximately 1% of fair market value, with additional millages levied by various local taxing authorities and special districts throughout the parish.

Property tax rates in St. Bernard County vary significantly by location within the parish due to different combinations of special taxing districts, school districts, fire districts, and municipal services. Millage rates are expressed as tenths of a penny per dollar of assessed value rather than standard percentages. Property owners should note that most tax credits and exemptions require annual application and are not automatically applied to your assessment.

Supplemental Tax Bills

Supplemental taxes in St. Bernard County are triggered by changes in property ownership, new construction, or improvements that increase a property's assessed value during the tax year. When these events occur, a supplemental assessment is calculated based on the difference between the old and new assessed values, prorated for the remaining months in the tax year.

For example, if you purchase a home in June that was previously assessed at $150,000 but now has a market value of $250,000, you would receive a supplemental tax bill for the increased assessed value ($100,000 difference) covering July through December. The supplemental tax would be calculated as: ($100,000 × assessment ratio × applicable millage rate) × (6 months ÷ 12 months).

Escrow & Property Taxes

Most mortgage lenders in St. Bernard County require borrowers to maintain an escrow account for property taxes, collecting monthly payments along with principal and interest. Lenders typically collect 1/12th of the annual tax bill each month, plus an additional cushion amount allowed by federal law. Property taxes in Louisiana are due December 31st, and lenders usually pay the full annual amount by this deadline.

Property owners should verify that their lender has current tax information and is paying the correct amount. The St. Bernard Parish Tax Collector provides online access to verify payments and outstanding balances. If you pay taxes directly rather than through escrow, remember that interest begins accruing on January 1st for any unpaid balance, and properties can be subject to tax sale procedures if taxes remain delinquent.

The exemption amount may be adjusted annually, and you must maintain eligibility and file required documentation.

Q: When are properties assessed and how can I appeal? A: Properties are assessed annually. Assessment notices are typically mailed in late summer. You have the right to appeal your assessment through the Parish Assessor's Office if you believe it's incorrect or unfair.
