Informational notice
Figures describe the median homeowner household in St. Tammany Parish as reported to the Census Bureau; your parcel can differ. Not tax, legal, or financial advice: check the county assessor or a qualified professional before decisions that depend on these numbers.
Most of the market's rise reached the bill
The effective rate here moved 7.7% down between 2020 and 2024, a smaller shift than in 69% of U.S. counties. With the median home value rose 27.2%, the median bill rose 17.4% to $2,028: the rate did comparatively little to offset the market.
Effective rate is the published median bill divided by the published median home value, so the two multiply back to the bill exactly; the rate's movement here is derived from those two figures rather than read from the rounded published rate. Both are ACS 5-year survey estimates for the median owner-occupied household, compared across non-overlapping releases. They describe what the Census published, not a local policy, assessment, or exemption change.
How to read this county's bill
Bills rose across 2020-2024, from $1,728 to $2,028, a gain of 17%. This is a comparison of published ACS medians, not an explanation of a particular property's assessment or tax bill.
The heaviest band is also the fullest one here: 23,181 of 82,876 owner-occupied homes (28.0%) report annual real-estate taxes above $3,000. That band has no upper edge in the source, so the county median understates the burden carried by the plurality rather than describing it.
Top-quartile earnings meet a below-median rate, putting the median bill at 2.5% of median household income. Counties in this position span a wide range on the ratio above, because the dollar bill tracks home values rather than the rate.
The share above is the median annual bill divided by median household income, a ratio of two county-level medians rather than a household-by-household figure.
St. Tammany Parish is an outlier inside Louisiana
Across the 64 Louisiana counties with a published rate, the average effective rate is 0.43%. St. Tammany Parish is at 0.71%, which sits 2.1 standard deviations above that average. Fewer than one county in twenty nationally is this far from its own state's centre, so a state-level average is a poor guide to what is owed here.
Standard deviations are computed across every county in the state with a published effective rate for 2024; states with fewer than five such counties are not assessed.

Above Louisiana on both measures
St. Tammany Parish's effective rate runs 29% over the Louisiana median and its bill 72% over. When both move together the rate is not being offset by cheaper housing, so the $2,028 median bill is carrying the full weight of the higher rate rather than a valuation difference. This is a comparison of two published medians, not a statement about any individual parcel.

Each row is a separate ACS 5-year release, and consecutive releases share four of their five survey years. The percentage beside each bill is therefore movement in the published estimate against the previous release, not a single year's tax change. The two releases largely describe the same households. For change over time, compare releases that do not overlap.
