Property taxes in Louisiana are local taxes based on the assessed value of real and personal property. These taxes fund parish governments, public schools, municipalities, law enforcement, and other local services. Louisiana uses a constitutionally defined assessment system with statewide oversight, while tax rates are set locally by voter approved millages.
How Property Taxes Are Administered
- Parish assessors determine property values and assessments
- Parish tax collectors issue property tax bills and collect payments
- Parish governing authorities and school boards set millage rates
- The Louisiana Tax Commission provides statewide oversight and equalization
- Local boards of review hear assessment appeals
Valuation Method Used
Louisiana property is valued based on fair market value. Market value reflects the price a property would likely sell for between a willing buyer and seller.
Parish assessors use sales data, property characteristics, and cost information to determine value. Property is reassessed on a regular cycle, with updates required at least every four years or when significant changes occur.
Assessment Ratios
Louisiana applies fixed assessment percentages set by the state constitution:
- Residential property
- Commercial and industrial property
- Public service property
- Agricultural land assessed based on use value rather than market value
These assessment percentages are uniform statewide and applied consistently by parish assessors.
Calculation Process
Property taxes in Louisiana are calculated as follows:
- Fair market value is determined by the parish assessor
- The applicable assessment percentage is applied
- Exemptions are subtracted from assessed value
- Voter approved millage rates are applied
- The combined millages determine the total tax owed
Millage rates vary by location depending on local taxing authorities.
Notices and Appeals
Property owners receive an annual assessment notice showing fair market value, assessed value, and applicable exemptions.
If an owner disagrees with the assessment, an appeal may be filed with the local board of review during the designated appeal period. Appeals may then be taken to the Louisiana Tax Commission if needed.
Payment Schedule
Louisiana property taxes are billed annually.
- Tax bills are typically issued in the fall
- Payments are generally due by the end of the calendar year
- Delinquent taxes may result in interest and penalties
Exact billing and due dates can vary by parish.
Exemptions and Relief Programs
Common property tax exemptions and relief programs in Louisiana include:
- Homestead exemption for owner occupied primary residences
- Special assessment levels for qualifying veterans with service related disabilities
- Agricultural use valuation for qualifying farmland
- Exemptions for government owned property
- Exemptions for qualifying religious, charitable, and nonprofit property
Most exemptions require application with the parish assessor.
Reasons Taxes May Change
- Reassessment or changes in market value
- New construction, improvements, or demolition
- Changes in millage rates approved by voters
- Addition or loss of exemptions
- Changes in property use or classification
Practical Tips for Owners
- Review assessment notices carefully each year
- Ensure homestead exemptions are properly applied
- Monitor local millage elections and renewals
- Compare your assessment with similar properties
- File appeals within the allowed timeframe if values appear inaccurate
Final Thoughts
Louisiana’s property tax system combines market based valuations with constitutionally defined assessment percentages and locally approved millage rates. Because both assessed value and voter approved taxes affect the final bill, understanding assessments and exemptions is essential. Regular review of notices and awareness of local tax decisions can help Louisiana property owners manage property taxes more effectively.
