A real AppealDesk order, Harris County, Texas
In June 2026, a homeowner in Harris County, Texas ran the check. The county had their home on record at $3,148,044, while recorded sales of comparable homes supported about $2,391,577: an over-assessment of $756,467, worth roughly $11,138 per year if corrected. Their packet laid out the comparable sales, the forms, and the filing steps. Nobody at the county was ever going to run that check for them.
A deadline you meet with no evidence behind it is just paperwork. Comparable sales are what boards actually respond to, and pulling your county's number is where that starts.

Whether dealing with hurricane damage in Lake Charles, flooding in New Orleans, or subsidence in Baton Rouge, Louisiana property owners face unique challenges that assessors often miss.
The combination of Napoleonic law traditions, parish autonomy, and natural disaster impacts makes Louisiana property tax appeals particularly important - and particularly winnable with proper evidence.
Critical Note: Louisiana has 64 parishes with different appeal deadlines and procedures. Urban parishes typically use fixed dates (August-September), while rural parishes often use "days from notice" rules. Always verify your specific parish deadline with the assessor's office. Hurricane and flood damage documentation is essential statewide.
