How to Appeal Property Taxes in Louisiana: Step-by-Step Guide for 2026
TL;DR
Louisiana homeowners can appeal their property tax assessment by filing with their Parish Board of Review (during open books period). The deadline is within 15 calendar days of the assessment list being exposed (typically mid-August to mid-September). The average effective property tax rate in Louisiana is 0.56%, and the average homeowner pays around $1,092 per year on a $195,000 home. If your assessment is too high, an appeal could save you hundreds or even thousands annually.
Property taxes in Louisiana are based on your property's assessed value, which is determined by your county assessor. If that value is too high, you pay more than you should. The appeal process exists specifically to correct these errors, and it costs nothing to file.
Here is exactly how to appeal your property taxes in Louisiana in 2026, including deadlines, procedures, and tips for building a winning case.
How Louisiana Property Tax Assessments Work
Louisiana assesses property at 10% for residential. The valuation date is varies by parish (assessments updated every 4 years), meaning your property's value is based on market conditions as of that date. Assessment lists are 'exposed' (made public) for 15 days, typically August-September.
The fiscal year runs January 1 - December 31. Tax bills are calculated by multiplying your assessed value by the local mill rate (or tax rate), which is set by your county, city, school district, and other taxing authorities.
Key Deadlines for 2026
| Event | Deadline/Date |
|---|---|
| Valuation date | varies by parish (assessments updated every 4 years) |
| Assessment notices mailed | Assessment lists are 'exposed' (made public) for 15 days, typically August-September |
| Appeal deadline | Within 15 calendar days of the assessment list being exposed (typically mid-august to mid-september) |
| Further appeal | Louisiana Tax Commission, then district court |
Step-by-Step: How to Appeal Your Louisiana Property Tax Assessment
Step 1: Review Your Assessment Notice
When you receive your notice, check every detail. Verify the square footage, lot size, number of bedrooms and bathrooms, year built, and any special features. Errors in property characteristics are the easiest wins in an appeal because the facts speak for themselves.
Step 2: Research Comparable Sales
Look for 3-5 homes similar to yours that sold near the valuation date (varies by parish (assessments updated every 4 years)) for less than your assessed value. Good comps share your neighborhood, approximate size, age, and condition. The closer the match, the stronger your case.
Step 3: File Your Appeal
File your appeal with the Parish Board of Review (during open books period) within 15 calendar days of the assessment list being exposed (typically mid-August to mid-September). In most Louisiana counties, you can file by mail, in person, or online (check your county assessor's website). Include a written explanation of why you believe your assessment is too high, along with your supporting evidence.
Step 4: Prepare Your Evidence
Strong evidence includes:
- Comparable sales data: Recent sales of similar properties at lower values
- Property condition issues: Foundation problems, outdated systems, needed repairs, environmental issues
- Photos: Document any defects or conditions that reduce your property's value
- Equity arguments: Show that comparable properties in your area are assessed lower than yours
- Independent appraisal: A recent professional appraisal showing a lower value
Step 5: Attend Your Hearing
Present your case clearly and concisely. Stick to facts and data. Bring copies of all evidence for the board members. Be respectful but firm. If you have a professional appraisal or contractor estimates for repairs, those carry significant weight.
Step 6: Further Appeals If Needed
If you disagree with the Parish Board of Review (during open books period)'s decision, you can escalate to Louisiana Tax Commission, then district court. Each level of appeal has its own deadlines, so act quickly if you want to continue.
County-Specific Appeal Information
Orleans Parish (New Orleans)
New Orleans assessors divide the city into seven assessment districts, each with its own assessor. This can create inconsistencies. File your appeal during the open books period with your district assessor.
East Baton Rouge Parish
The state capital parish. The East Baton Rouge Assessor handles one of the largest property rolls in Louisiana. Appeals go through the Board of Review during open books.
Jefferson Parish
Part of the New Orleans metro. Jefferson Parish assessments can lag behind market changes due to the 4-year reassessment cycle.
Caddo Parish (Shreveport)
Northwest Louisiana's largest city. Oil and gas activity can influence property markets. Check that the assessor is using appropriate local comps.
Louisiana Property Tax Exemptions
Before or alongside your appeal, make sure you are claiming every exemption you qualify for. Exemptions reduce your taxable value directly, saving you money every year.

Tips for a Successful Louisiana Property Tax Appeal
Focus on Comparable Sales
The single most persuasive piece of evidence is comparable sales data showing similar homes sold for less than your assessed value. Boards and assessors deal in market data. Give them solid numbers.
Check for Property Record Errors
Assessors work from property records that may contain mistakes. Wrong square footage, extra bathrooms, incorrect lot size, or a missing condition note can inflate your value. Verify everything against your actual property.
Document Property Condition Issues
If your home needs a new roof, has foundation issues, or has other problems that a buyer would negotiate on, document them with photos and repair estimates. The assessor may not know about these issues.
File Every Year
Even if you won last year, your assessment can go up again this year. Make annual appeals part of your routine. There is no penalty for appealing, and your assessment cannot go up as a result of your appeal in most jurisdictions.

Frequently Asked Questions
What is the deadline to appeal property taxes in Louisiana?
The deadline is within 15 calendar days of the assessment list being exposed (typically mid-August to mid-September). Missing this deadline generally means waiting until next year, so mark your calendar.
How much does it cost to appeal property taxes in Louisiana?
Filing an appeal is free. You may incur costs only if you hire a professional appraiser, attorney, or if you escalate to court. The initial appeal to the Parish Board of Review (during open books period) costs nothing.
Can my property taxes increase if I appeal?
In most cases, your assessed value will not increase as a result of filing an appeal. The worst outcome is typically that your value stays the same. However, if the review board discovers a significant error that understated your value, a correction is possible in rare cases. This is uncommon.
Do I need a lawyer to appeal?
No. The appeal process is designed for property owners to handle themselves. For high-value or complex properties, professional help can be worth it, but most residential appeals are straightforward.

The initial appeal typically takes 1-3 months from filing to decision. Further appeals to Louisiana Tax Commission, then district court can take additional months.
What evidence works best in a property tax appeal?
Comparable sales of similar homes that sold for less than your assessed value are the strongest evidence. Property condition documentation, independent appraisals, and equity comparisons with similarly assessed nearby properties also carry weight.
