How Property Tax Works

St. Landry Parish operates under Louisiana's property tax system, where property taxes fund essential local services including schools, law enforcement, fire protection, libraries, and parish infrastructure. Property taxes in St. Landry Parish are administered by the parish assessor for valuation and the parish sheriff for collection, following Louisiana's decentralized assessment and collection model.

The effective tax rate in St. Landry Parish varies significantly by location within the parish due to multiple special taxing districts, including school districts, fire protection districts, library districts, and municipal services. Property owners can expect rates ranging from approximately 0.8% to 1.2% of assessed value, depending on their specific location and the combination of taxing authorities that serve their property. All tax rates are set annually by the respective governing bodies, meaning rates can change each fiscal year based on local budget needs and millage elections.

Section 4

Supplemental Tax Bills

Supplemental taxes in St. Landry Parish are additional property tax bills issued when there are changes in property ownership, completion of new construction, or improvements that increase a property's assessed value during the tax year. These supplemental assessments ensure that tax obligations reflect current property conditions and ownership.

Supplemental taxes are calculated by applying the current tax rate to the difference between the new assessed value and the previous assessed value, prorated for the portion of the tax year remaining after the change occurred. For example, if a property improvement adding $50,000 in assessed value is completed in July (halfway through the tax year), the supplemental tax would be calculated on $50,000 at the applicable tax rate, then multiplied by 50% to reflect the partial year. The supplemental bill is typically issued 30-60 days after the assessor processes the change and is due within 30 days of the bill date.

Escrow & Property Taxes

Most mortgage lenders in St. Landry Parish require borrowers to maintain an escrow account for property taxes, especially when the loan-to-value ratio exceeds 80%. The lender collects monthly escrow payments along with principal and interest, typically calculated as the annual tax bill divided by 12, plus a two-month cushion as allowed by federal law.

Property tax bills in St. Landry Parish are due October 1st and become delinquent January 1st of the following year. Lenders typically pay the tax bill in late November or December to ensure timely payment and avoid penalties. Property owners should verify that their lender has received the correct tax bill amount, as supplemental taxes or assessment changes may not be automatically included in escrow calculations. The St. Landry Parish Sheriff's Office provides online access to current tax bills and payment history, allowing property owners to monitor their account and confirm payments.

Frequently Asked Questions

Q: When are property taxes due in St. Landry Parish? A: Property taxes are due October 1st and become delinquent on January 1st of the following year. The ad valorem tax must be paid by December 31st to avoid penalties.

Q: What homestead tax credit is available and how do I apply? A: Louisiana's homestead exemption reduces the first $7,500 of assessed value for primary residences and caps annual assessment increases. You must file an application with the St. Landry Parish Assessor's Office. This is not automatic and requires documentation proving the property is your primary residence.

Q: Are there tax credits for seniors or veterans? A: Yes, Louisiana offers additional tax credits for seniors over 65, disabled veterans, and surviving spouses of veterans. These require separate applications with income and eligibility documentation filed with the parish assessor by the annual deadline.

Q: How often are properties reassessed? A: Louisiana law requires properties to be reassessed every four years, though the assessor may conduct interim assessments for improvements or ownership changes.

Q: What happens if I pay my taxes late? A: Interest begins accruing on January 1st at 1.25% per month. Additional penalties may apply, and the property may eventually be sold at a tax sale if taxes remain unpaid.

Q: Can I pay my property taxes online? A: Yes, the St. Landry Parish Sheriff's Office typically offers online payment options through their website. Check with the sheriff's tax department for available payment methods and any associated fees.

Q: How do special district taxes work? A: Your property may be located within multiple special taxing districts (fire, library, drainage, etc.). Each district sets its own millage rate, and all applicable rates are combined on your tax bill based on your property's location.

Q: How do I appeal my property assessment? A: Assessment appeals must be filed with the St. Landry Parish Assessor's Office by September 15th following the assessment. If unsuccessful, you can appeal to the Louisiana Tax Commission within 60 days of the assessor's decision.
