How this is calculated

The effective property tax rate is the median real-estate tax bill divided by the median home value — both for owner-occupied homes, from the U.S. Census Bureau's American Community Survey (ACS 5-year estimates)1. Median income is also from the ACS1. Federal and state income-tax figures use IRS2 and Tax Foundation3 data.

About St. John the Baptist Parish, LA

Property taxes in St. John the Baptist Parish run at an effective rate of 0.454%, which edges past Louisiana's statewide median of 0.438%. That gap places the parish 25th among the state's 64 counties, so it sits somewhat above the middle of the pack locally. Set against the national median of 0.794%, though, the picture changes: homeowners here pay noticeably less than what many Americans face. A median home value of $193,200 generates an annual tax bill of about $877. With median household income at $66,630 and per-capita income of $30,132, that yearly charge stays contained. Communities like Edgard, Garyville, and Mount Airy reflect the parish's mix of small towns and industrial corridors along the Mississippi. The rate signals a jurisdiction that taxes property more heavily than most of its Louisiana peers but still well below the countrywide norm.

Frequently asked questions

What is the property tax rate in St. John the Baptist Parish, LA?

How does the effective rate differ from my mill rate?
