Calculating Your Taxes
Please note: The following are examples with arbitrary Millage Rates. Please refer to the
Millage Rates applicable to your particular property. These rates vary by location within the parish.
Once the assessed value of an asset is determined, the amount of taxes owed on that asset
can be calculated. Louisiana Law dictates that all Land - commercial and residential - is assessed
at 10% of market value. Residential buildings are assessed at 10 % and Commercial buildings
are assessed at 15% of market value. Commercial personal property, also known as movable
property, is assessed at 15% of market value.
To calculate taxes, the millage rate is applied to the assessed value. Remember that 1 mill is
equal to $0.001 of value. Therefore, if the millage rate is 89.50 mills, then the tax amount due
on $17,500 assessed value would be $1566.25. (See Example 1)
Example 1
Residential Property without Homestead Exemption
Land market value = $ 35,000 x 10% = assessed Land value = $ 3,500
House market value = $ 140,000 x 10% = assessed House value = $ 14,000
Total market value = $ 175,000 Total assessed value = $ 17,500
Millage Rate 89.50 = x 0.0895
Parish taxes owed = $1566.25
Example 2
Residential Property with Homestead Exemption
Land market value = $ 35,000 x 10% = assessed Land value = $ 3,500
House market value = $ 140,000 x 10% = assessed House value = $ 14,000
Total market value = $ 175,000 Total assessed value = $17,500
Homestead Exemption - $ 7,500
Net assessed value $10,000
Millage Rate 89.50 = x 0.0895
Parish taxes owed = $895.00
(If Property is located inside City Limits)
City Taxes:
Total Assessed value = $17,500
City Millage Rate 10.00 x $ 0.010
City taxes owed = $175.00
Remember that the homestead exemption does not apply to municipal taxes. Municipal (City)
property taxes would be levied on the $17,500 in assessed value for the above home.
For 10.00 mills in municipal tax, the taxpayer would owe an additional $175.00.
Example 3
Commercial Property
Land market value = $ 35,000 x 10% = assessed land value of $ 3,500
Building market value = $ 140,000 x 15% = assessed building value of $ 21,000
Total market value = $ 175.000 Total assessed value = $ 24,500
Millage Rate 89.50 = x 0.0895
Parish taxes owed = $ 2,192.75
Using the values from Example 2, with a tax rate of 89.50 mills, and applying homestead
exemption to the residential property, one should note the difference in the tax amount
owed by a homeowner (Example 2) versus the owner of a commercial building with the same market value.
