Property Tax Bills Across Jefferson County, Louisiana
Property tax bills in Jefferson are based on the assessed value of a home, not its market price alone. Local tax rates are applied to that assessed value, and the final bill can also reflect exemptions, special assessments, and other local charges. Because the bill is tied to value, two homes with similar market prices may still owe different amounts if their assessments or tax rates differ.
For homeowners, this means property taxes can change when a home’s assessed value changes or when local rates are adjusted. In Jefferson, the median home price is $138,733, which helps explain why bills vary widely across the county. The 25th percentile tax bill is $563, while the 75th percentile is $2,388 and the 90th percentile is $4,503. That range shows how much location, assessment, and local taxing authorities can affect what a homeowner pays.
