Property taxes are the largest local tax most homeowners pay. The effective rate measures the real tax bill as a share of home value — a more useful number than the nominal “mill rate,” because assessment practices vary county to county.

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. James Parish, LA

Buying a home in St. James Parish means weighing a median value of $211,800 against an annual property tax bill of about $1,113, based on an effective rate of 0.525%. That rate sits above Louisiana's statewide median of 0.438% and ranks 16th among the state's 64 counties, so taxes here run somewhat higher than in much of Louisiana — yet they remain well below the national median of 0.794%. Households earning a median of $65,531, with per-capita income at $37,140, would find that bill equals roughly 1.7% of typical annual earnings. Communities like Gramercy, Lutcher, and Saint James anchor the parish, offering small-town settings along the Mississippi River. For buyers, the combination of moderate home prices and taxes that stay under the national average keeps overall housing costs within reach, even if Louisiana's own lower-tax counties offer a slight edge.

Frequently asked questions

What is the property tax rate in St. James Parish, LA?
The effective rate is 0.53% — meaning the median tax bill equals about 0.53% of the median home value.
How much are property taxes on a median home?
On the median home ($211,800), the estimated annual bill is about $1,113.
Is St. James Parish's rate high or low?

How does the effective rate differ from my mill rate?
A mill rate is the nominal levy per $1,000 of assessed value. The effective rate reflects what you actually pay after exemptions and assessments — it's the median tax bill as a share of median home value, so it better predicts your real cost.
Will a reassessment raise my tax bill?
Not necessarily. If your home's assessed value rises, your bill can go up, but only if the mill rate and exemptions stay flat. Contact the St. James Parish assessor's office to review your current assessment.
Can I appeal my property tax assessment?
Yes. Most counties allow an appeal when you believe the assessed value exceeds the market value. File with the St. James Parish assessor within the local deadline, typically with comparable sales as evidence.
