How Property Tax Works

Iberia Parish (County), Louisiana operates under a property tax system that serves as the primary funding source for essential local services including schools, law enforcement, fire protection, and infrastructure maintenance. Property taxes in Iberia Parish are assessed annually on a calendar year basis, with the parish assessor determining property values and various taxing authorities setting millage rates to fund their operations.

The effective property tax rate in Iberia Parish varies significantly based on your property's location within specific taxing districts, as multiple overlapping jurisdictions levy taxes including the parish government, school districts, municipalities, and special districts for services like drainage, fire protection, and library services. Property owners typically see total effective rates ranging from approximately 0.8% to 1.2% of assessed value, though this can vary based on applicable tax credits and the specific combination of taxing districts where your property is located.

It's important to note that Louisiana uses an assessment ratio system, and actual tax bills depend on both the millage rates set by various taxing authorities and any tax credits you may qualify for and apply to receive. These credits can significantly reduce your annual tax obligation but require proper application and documentation.

Note: One mill equals $1 per $1,000 of assessed value. Total millage rates typically range from 45-80 mills depending on your property's specific location within various overlapping taxing districts. Official rates for the current levy year are set annually by each taxing authority and may differ from these estimates.

Section 3

Section 4

Supplemental Tax Bills

Supplemental taxes in Iberia Parish are triggered when there are changes to property ownership, new construction, or significant improvements that increase a property's assessed value during the tax year. These situations require a recalculation of the annual tax obligation to account for the changed circumstances.

When a supplemental tax is levied, it covers the period from when the change occurred through the end of the current tax year. For example, if you purchase a home in June that was previously assessed at a lower value, or if you complete a major renovation that increases your property's assessed value, the tax collector will issue a supplemental bill for the additional taxes owed from the effective date through December 31st.

The calculation is prorated based on the number of months remaining in the tax year. If new construction is completed in September, you would owe 4/12ths (September through December) of the additional annual tax created by the increased assessment. Supplemental bills are typically issued within 60-90 days of the assessor receiving notice of the change and are due within 30 days of the bill date.

Escrow & Property Taxes

Most mortgage lenders in Iberia Parish require property tax escrow accounts for borrowers with less than 20% down payment, though some may require escrow regardless of down payment amount. Your lender collects monthly escrow payments equal to 1/12th of your estimated annual property tax bill, plus a cushion amount typically not exceeding two months of payments.

Property taxes in Iberia Parish become due on November 15th each year and become delinquent on December 31st. Lenders typically pay your property taxes in late November or early December to ensure timely payment and avoid penalties. Your mortgage servicer will receive the tax bill directly from the Iberia Parish Tax Collector's office and handle payment from your escrow account.

Each year, your lender conducts an escrow analysis to compare the actual taxes paid versus the amount collected through monthly payments. If property taxes increase due to higher assessments or millage rates, your monthly escrow payment may increase. If you believe your lender's escrow analysis is incorrect, you can request a review and provide documentation of the correct tax amounts. Property owners should verify that their lender has the correct tax bill information, as mistakes can result in underpayment and potential penalties.

Frequently Asked Questions

Q: When are property taxes due in Iberia Parish for the current tax year? A: Property taxes become due on November 15th annually and become delinquent on December 31st. Taxes paid after December 31st are subject to penalty and interest charges.

Q: What homestead exemption am I eligible for and how do I apply? A: Louisiana's homestead exemption removes the first $7,500 of assessed value for your primary residence from all ad valorem taxes. You must apply with the Iberia Parish Assessor's office by September 1st following the year you acquire the property. The exemption is not automatic and requires proof of residency.

Q: How does the homestead exemption affect assessment increases? A: The homestead exemption also caps assessment increases on your primary residence to 10% per year, providing protection against rapid property value appreciation. This cap applies to the portion of your property covered by the homestead exemption.

Q: Are there other tax credits available in Iberia Parish? A: Yes, additional credits may include the special assessment level (SAUL) program for certain improvements, disability exemptions, and senior citizen exemptions. Each requires separate application with specific documentation and deadlines. Contact the Iberia Parish Assessor at (337) 369-4405 for details.

Q: How often are properties reassessed in Iberia Parish? A: Louisiana requires property reassessment every four years, with the most recent general reassessment completed in 2020. The next general reassessment is scheduled for 2024. However, properties may be reassessed individually due to sales, improvements, or appeals.

Q: How do I appeal my property assessment? A: Assessment appeals must be filed with the Iberia Parish Assessor's office by September 1st. If unsatisfied with the assessor's decision, you may appeal to the Louisiana Tax Commission by October 1st. Professional appraisals and comparable sales data strengthen your appeal.

Q: What penalties apply for late property tax payments? A: Properties become delinquent on January 1st following the due date. Louisiana law imposes penalty and interest charges on delinquent taxes, and properties may eventually be subject to tax sale if taxes remain unpaid for three years.

Q: Can I pay my property taxes online? A: Yes, the Iberia Parish Tax Collector accepts online payments through their official website. Convenience fees may apply for credit card payments. You can also pay by mail, in person, or through certain authorized payment locations.

Q: Why did I receive a supplemental tax bill? A: Supplemental bills are issued when property changes ownership, new construction is completed, or improvements increase assessed value during the tax year. The bill covers additional taxes owed from the change date through December 31st on a prorated basis.

Q: How do special district taxes affect my bill? A: Your property may be located within multiple special taxing districts for fire protection, drainage, libraries, or other services. Each district sets its own millage rate, and the combination determines your total tax rate. Contact the Tax Collector's office at (337) 365-7282 to identify which districts apply to your property.
