estimated annual property tax
ACS 2020-2024 ratio of medians. This estimate does not use your parcel’s assessment or district tax rates.

Your actual bill depends on your local assessment, exemptions, and taxing districts.
A home value. A yearly budget.

What can change your bill?
The ACS effective rate is a ratio of medians, not a statutory rate. Local assessed values, levies, classification, caps and exemptions determine the actual bill.
Exemptions & assessment
No uniform flat exemption is applied. Enter your assessor-provided assessment ratio and qualifying exemption for a separate statutory scenario.
Payment dates & appeals
The parish collector's bill controls. Plaquemines Parish's 2026 calendar gives December 31 as the payment deadline, with delinquency afterward; confirm the bill in your own parish.
Parish inspection and Board of Review dates are advertised locally. Plaquemines' 2026 calendar opened books August 15-31 and set September 17 for a board appeal. Later Tax Commission and court reviews are separate.
Check Louisiana’s official property-tax guidance
Use an assessed value, exemption, and local millage
This separate scenario needs your assessor’s inputs. An exemption applies only to eligible levies; do not apply it to the county’s historical effective rate.
Good questions. Clear answers.
How much is property tax on a $400,000 home in Louisiana?
The historical effective-rate estimate is $2,180 per year, or $182 a month. It multiplies $400,000 by 0.55%.
Is the effective rate the rate on my tax bill?
No. It is median real-estate taxes paid divided by median home value in the ACS 2020-2024 survey. Your taxing districts, assessed value, classification and exemptions determine your bill.
Can I subtract a homestead exemption from this estimate?
Use the separate statutory scenario with a qualifying levy. Subtracting an exemption from an ACS effective-rate estimate can double-count relief already reflected in taxes paid.
Does a higher purchase price change my assessment?
Assessment rules and reassessment dates vary by state and locality. Contact the linked official property-tax office before relying on a historical county ratio.
How do I appeal a property-tax assessment?
Read the deadline and procedure on your assessment notice, then use the official state guidance above to locate your assessor or review board. County survey data does not establish your appeal deadline.
Check the source.
