How to read these numbers
- These are estimates from a survey, not a count. The American Community Survey asks a sample of households. The ± figure is the Census Bureau’s margin of error: the true value is very likely within that range of the estimate. Small places have large margins.
- “Too imprecise to report” means the margin of error is at least half of the estimate, so printing the number would suggest accuracy that does not exist. A “rough guide only” note means the margin is a quarter to a half of the estimate.
- Property tax bill and home value are medians for owner-occupied homes. Half of the homes are above the figure and half below. A median bill is not the rate set by a city or town; the bill combines taxes levied by every local government that serves the home, such as the school district and county.
- “Calculated” rows are worked out by Untax the Roof from the Census figures above them. They compare two medians, so they describe the place, not a particular household.
- Missing is not zero. Where the Census Bureau publishes no figure, this page says so.

If property taxes go unpaid in Louisiana
How it works. For tax liens arising under the post-2025 regime, political subdivision conducts tax-lien auction/certificate process followed by judicial recognition/enforcement and sheriff judicial sale; older tax-sale-title/adjudication cases remain under legacy rules
Excess sale money. R.S. 47:2267 distributes judicial-sale proceeds after costs to certificate holder, other tax-lien holders, recorded mortgages/liens/privileges, then to each owner according to interest; undeliverable surplus goes to court registry and after one year to unclaimed-property process. R.S. 47:2211 separately governs excess proceeds for certain political-subdivision sales
These rules are set by Louisiana, not by Slidell, so this section is the same for every place in the state. Last verified 2026-09-25. See the full Louisiana entry with statute links.
