How Property Tax Works

Iberville Parish (County), Louisiana operates under the state's property tax system, where property taxes fund essential local services including schools, law enforcement, fire protection, and parish infrastructure. Property owners in Iberville Parish can expect effective tax rates that generally align with Louisiana's base rate of approximately 1% of assessed value, though actual rates vary significantly based on your specific location within the parish due to different combinations of special taxing districts.

The parish uses an assessed value system where properties are typically assessed at a percentage of market value, with various tax credits and exemptions available to qualifying property owners. Your total property tax bill consists of multiple components including parish-wide taxes, school district taxes, and special district assessments that may apply to your specific area. It's important to note that most tax credits and exemptions require annual application and are not automatically applied to your assessment.

Supplemental Tax Bills

Supplemental taxes in Iberville Parish are additional assessments that occur when there are changes to property ownership, new construction, or improvements made to existing properties during the tax year. These supplemental bills are calculated based on the difference between the old and new assessed values, prorated for the portion of the tax year remaining after the change occurred.

For example, if you complete a $100,000 home addition in March that increases your assessed value by $80,000, you would receive a supplemental tax bill for the increased assessment covering April through December of that tax year. The supplemental amount would be calculated as: ($80,000 × applicable tax rate) × (9 months remaining ÷ 12 months).

Escrow & Property Taxes

Most mortgage lenders in Iberville Parish require property tax escrow accounts, where you pay 1/12 of your estimated annual property tax bill with each monthly mortgage payment. Your lender holds these funds in an escrow account and pays your property taxes directly to the parish when due on December 1st each year.

Lenders typically collect an initial escrow deposit at closing and may require additional cushion amounts as allowed by federal regulations. You'll receive an annual escrow analysis statement showing how your funds were used and any adjustments needed for the coming year. If your property taxes increase due to reassessment or rate changes, your monthly escrow payment will be adjusted accordingly. Property owners should verify that their lender pays taxes on time, as you remain ultimately responsible for ensuring timely payment even when using escrow services.
