What you'll pay, at a glance

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 Assumption Parish, LA

Assumption Parish carries an effective property tax rate of 0.367%, which sits below Louisiana's statewide median of 0.438% and well under the national median of 0.794%. Among the state's 64 counties, it ranks 39th by rate. The owner of a home valued at the median $150,300 would owe roughly $552 a year in real-estate taxes. With a median household income of $51,423 and per-capita income of $31,516, that bill equals about one percent of household earnings. Communities such as Pierre Part, Belle Rose, and Labadieville fall within the parish. A rate this far beneath the national figure signals that property taxes take a smaller share of local budgets than in most of the country, though the parish's ranking within Louisiana places it somewhat closer to the middle of the pack statewide.

Frequently asked questions

What is the property tax rate in Assumption Parish, LA?
The effective rate is 0.37% — meaning the median tax bill equals about 0.37% of the median home value.
How much are property taxes on a median home?
On the median home ($150,300), the estimated annual bill is about $552.
Is Assumption Parish's rate high or low?
Compare it to the state median of 0.44% and the national average near 1.1%.
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 Assumption 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 Assumption Parish assessor within the local deadline, typically with comparable sales as evidence.
