What is the property tax rate in New Orleans?

The effective property tax rate in Orleans Parish runs around 0.57% of market value. Louisiana assesses residential property at 10% of fair market value, then applies the parish millage to that assessed amount.

How does the Louisiana homestead exemption work?

The homestead exemption removes the first $7,500 of assessed value — equivalent to $75,000 of market value — from taxation for an owner-occupied primary residence. On a typical home it eliminates the parish portion on that first slice of value.

How is assessed value calculated?

Louisiana assesses residential property at 10% of fair market value, so a $300,000 home has a $30,000 assessed value. Commercial and other property is assessed at a higher ratio. The millage rate is then applied per $1,000 of taxable assessed value.

Does the homestead exemption apply to rentals or commercial property?

No. The homestead exemption is only for an owner-occupied primary residence. The tool disables it for commercial property and for residential property when you uncheck the homestead box.

Is this an exact tax bill?

No. It is an estimate using a representative Orleans Parish millage. Special districts, fees, and millage changes can shift the figure, so confirm with the Orleans Parish Assessor for an exact bill.

Louisiana property taxes work differently from most states: homes are assessed at just 10% of market value, and a generous homestead exemption shields the first $75,000 of value for owner-occupants. The result is a low effective rate near 0.57% in Orleans Parish. This free estimator turns your home’s value into an estimated annual bill.

How it works

The estimator follows Louisiana’s two-step method. Assessed value is a fixed fraction of market value, the homestead exemption is subtracted from that assessed amount, and the millage is applied per $1,000 of taxable value:

assessed   = market_value * 0.10          (residential ratio)
taxable    = max(assessed - 7500, 0)      (homestead = $7,500 assessed)
annual_tax = taxable * (mill_levy / 1000) (~57 mills)

Commercial property uses a higher assessment ratio and is not eligible for the homestead exemption, which the tool handles automatically.

Notes and example

A $300,000 owner-occupied home assesses at $30,000; the homestead exemption removes $7,500, leaving $22,500 taxable. At roughly 57 mills the estimated annual tax is about $1,283, an effective rate near 0.43% after the exemption. Without the exemption the same home runs closer to 0.57%.
