West Baton Rouge Parish homeowners pay a median of $1,251 a year in property tax on a median home value of $229,900. Its effective tax rate (property taxes paid as a share of home values, per the Tax Foundation) is 0.47%, the 15th highest of 64 Louisiana parishes. The West Baton Rouge Parish Assessor sets the fair market value of every home in West Baton Rouge Parish and keeps the assessment rolls. Your assessed value is 10% of that value. The parish governing authority, sitting as the West Baton Rouge Parish Board of Review, hears appeals.
Closed for 2026The 2026 Board of Review deadlines have passed in every parish (Orleans for tax year 2027 closed August 20, 2026). If the board already ruled on your appeal, you have 30 calendar days from its decision to appeal to the Louisiana Tax Commission; Orleans decisions are being mailed from the week of October 19, 2026. The next window opens with the 2027 open-rolls period: 15 days between August 15 and September 15, 2027 in most parishes, and July 15 to August 16, 2027 in Orleans.
Outside Orleans Parish, the rolls are open for 15 days, sometime between August 15 and September 15 (Jefferson Parish may start August 1). Your written appeal on Form 3101 must reach the parish Board of Review at least 7 days before its public hearing, filed in person, by certified mail or by fax. Each parish sets and publishes its own dates. Example: in Claiborne Parish for 2026, the rolls were open September 1-15, the Police Jury sat as the Board of Review on September 9, and the last day to file a written appeal was Wednesday, September 2, 2026. Orleans Parish is different: the rolls are open July 15 to August 15 (to the next business day if August 15 falls on a weekend), and the appeal must reach the assessor's office within three business days after that. For the 2027 tax year, the rolls were open July 15-August 17, 2026 and the appeal deadline was August 20, 2026.

This office values your home, runs the open-rolls inspection period, mails a notice if your assessment rises 15% or more, and handles homestead exemptions and the senior freeze.
Each year the assessor opens the assessment lists ('open rolls' or 'open books') for public inspection and advertises the dates in the local newspaper. If your assessment goes up 15% or more from last year, the assessor must mail you a notice (Form TC-2) before the rolls open. Otherwise you may get no notice, so check your value online or at the assessor's office during the open-rolls period. You can also ask the assessor in writing, between June 1 and June 15, to send you this year's assessment.
Look up your home on the West Baton Rouge Parish Assessor website and check square footage, bathrooms, condition and features. Mistakes are the easiest wins. Use our record card checklist.
Check your value when the West Baton Rouge Parish Assessor opens the rolls for public inspection (the dates are published in the local newspaper). If talking to the assessor does not fix it, file Form 3101 with the West Baton Rouge Parish Board of Review in person, by certified mail or by fax so it arrives at least 7 days before the board's hearing. (Orleans Parish uses its own complaint form, filed through the assessor's office.) In Orleans Parish, file through the assessor's office within three business days after the rolls close.
A recent appraisal of your home (order it before the Board of Review deadline if you can); Your purchase price, if you bought recently in a normal sale; Recent sale prices of similar homes nearby; Photos, insurance records and contractor repair estimates showing damage or poor condition.
You are challenging the assessor's value, so you need evidence of your home's fair market value. At the Board of Review, each assessment is judged on its own merits using recognized appraisal methods. At the Tax Commission, the commission can change the value if the assessment is not supported by a preponderance of the evidence, based on its own review of all the evidence. If you then go to district court, the judge reviews the commission's decision under the state Administrative Procedure Act.
Next step: Louisiana Tax Commission (LTC). 30 calendar days from the earlier of the date the Board of Review's written decision is sent or the date you actually receive it. (The New Orleans City Council's FAQ still says 10 business days for Orleans appeals, so Orleans owners should file as early as possible.) File Form 3103.A with the Louisiana Tax Commission (P.O. Box 66788, Baton Rouge, LA 70896; 225-219-0339), attaching a copy of the Board of Review's decision and notice letter. You can file on the commission's website or by registered or certified mail (the mailing date counts). Re-file any evidence you gave the assessor or the board, because the board does not send its record. You must pre-file your evidence at least 45 days before the hearing. The commission's staff appraiser prepares its own appraisal, and the commission decides the value by a preponderance of the evidence. After that, you have 30 days to sue in district court. Taxes that come due while the suit is pending must be paid under protest or secured by bond; no payment is required while the commission challenge is pending.
The official appeal form is 3101: Appeal to Board of Review by Property Owner/Taxpayer (Exhibit A), Louisiana Tax Commission.
Open Form 3101Enter the market value on your assessment notice and what you think the home would really sell for. We estimate the yearly saving if the board agrees with you.
Some states cap how fast the taxable value of a home can rise (California, Florida, Michigan and Texas homesteads, for example). If your taxable value is already held below market value by a cap, a lower market value may not lower this year's bill.
