Baton Rouge Homestead Exemption: How It Lowers Your Property Tax
The Louisiana homestead exemption exempts the first $7,500 of assessed value from property taxes. On a $10,000 assessed home at a 0.100 rate, that cuts the bill from $1,000 to $250.
A Baton Rouge homestead exemption removes the first $7,500 of your home's assessed value from property taxes. [1] That is the starting point for estimating how much you can save each year. Related reading: Arkansas homestead exemption requirements: how to qualify and apply.
Only one homestead exemption applies per landowner, so you cannot claim it on several properties you own. [2] If you hold more than one property, the exemption covers only one of them. You may also find this useful: Alabama homestead exemption requirements and how to apply.
This article shows how the exemption changes your bill with a worked example, which taxes it reduces, and how to estimate your own amount. Confirm the current amount with your parish assessor before you budget, because the amount can change. To go further, see Cost of Living in Baton Rouge, LA: What Households Spend.
What changes your property tax bill?
The millage rate is applied to that smaller number, not to the full assessment, so the exemption lowers your bill.
The rate is the same in both columns, so the exemption is the only thing that changes the result.
Which taxes does the exemption reduce?
The homestead exemption removes up to $7,500 of your home's value from three kinds of tax: state, parish and special ad valorem taxes [2]. Because it reaches several levies, its effect shows up across your whole property tax bill, not on a single line.
Each of those levies is figured on the value that remains after the exemption comes off. A parish levy, a state levy and a special levy each shrink for the same reason, so the savings add up across the bill.
For example, if you live in one house and rent out a duplex, only the house you live in can carry the exemption. The duplex is taxed without it. For more detail, see Average Rent in Baton Rouge, LA: What the 2026 Figures Show.
How does the millage rate affect what you owe?
Your millage rate is the number that turns taxable value into a tax bill. A millage of 0.100 means $0.10 of tax for each dollar of taxable value [3]. So a higher millage means a higher bill on the same property.
Each taxing body sets its own rate
Your total bill is not one rate. Several taxing bodies each set a millage, and your bill adds them together. For example, one body might set 0.100 while another sets a different number, and each rate applies to the same taxable value. You need each figure separately before you estimate anything.
Rates change from year to year
Millage rates can change from one year to the next. A rate you read in an old notice or an older article may no longer apply. Because the rates are set each year, the total you pay can rise or fall even when your property stays the same. Use the current year's figures for every estimate.
Where to find the current millages
The parish assessor publishes current millages on its Assessments & Millages page [3]. Find the rate for each taxing body listed there, then apply those rates to your taxable value. Add the results together to see your total.
What should you do with this estimate?
Then multiply that taxable amount by the current millage. For a $10,000 assessment at 0.100, the math is ($10,000 – $7,500) x .100 = $250.00 [3].
Next, confirm the exemption is on your parish assessor's records [2]. If it is missing, the figure you calculate will not match what you actually owe, so fix the record before you plan your budget.
Treat the result as an estimate, because rates and assessments change. Pull the current millage from the Assessments & Millages page before you calculate, and you will have a number you can plan around.
