The Louisiana property tax rate works out to an effective 0.55% of a home’s fair market value, roughly half the national average of about 1.1%. The median annual bill lands near $1,187, which puts Louisiana among the four or five cheapest states in the country for property taxes. Two features of state law do most of the work: residential property is assessed at only 10% of its market value, and the first $7,500 of that assessed value is exempt from most taxes under the homestead exemption.
With median home prices near $259,000 in early 2026, a home at that price and the statewide average rate would generate about $1,425 in tax before the homestead exemption. After it, many homeowners pay well under $1,000. The statewide effective rate has stayed roughly flat for years, because the Louisiana Constitution limits how fast assessed values and millage rates can move.
How Your Tax Bill Is Actually Calculated
Louisiana does not tax the full market value of your home. Your parish assessor sets a fair market value, and then applies a fractional assessment percentage fixed by the state constitution. For residential property, that fraction is 10%, for both the land and the house on it. A home worth $300,000 carries an assessed value of $30,000 for tax purposes.
From that assessed value, the homestead exemption removes the first $7,500 on an owner-occupied primary residence, which corresponds to the first $75,000 of market value. The math on a $250,000 home looks like this:
- Market value: $250,000
- Assessed value at 10%: $25,000
- Minus homestead exemption: $7,500
- Taxable assessed value: $17,500
If your home is worth $75,000 or less, the exemption wipes out your taxable value for most purposes. The exemption applies only to your primary residence, not to rental property, a vacation home, or anything commercial, and you have to apply for it with your parish assessor.
What you owe in dollars depends on the local millage rate. One mill equals $1 of tax per $1,000 of assessed value. Your property sits inside overlapping taxing districts — schools, libraries, fire, drainage, sheriff, and others — and each district’s millage stacks into a single combined rate for your address. On a taxable assessed value of $17,500 and a combined 100 mills, the annual bill is $1,750. In the East Baton Rouge Parish area, combined millages typically fall between 90 and 120 mills depending on the exact location.
Louisiana reassesses property on a cycle of no more than four years. In reassessment years, taxing bodies often roll their millages back to stay revenue-neutral, so a rising market does not translate automatically into a bigger bill. Between reassessments, your assessed value generally stays put unless you build an addition or sell.
The Assessment Freeze for Homeowners 65 and Older
Louisiana offers a special assessment level that freezes the assessed value of a qualifying homeowner’s property. Once you qualify, your assessment cannot rise even if your neighborhood’s values climb at the next reassessment. The freeze locks in the assessment from the first year you qualify, not from the year you bought the home.
To qualify, you must meet all of the following:
- Be 65 or older.
- Have adjusted gross income on your prior-year federal return of no more than $100,000. This threshold begins adjusting annually for inflation starting in 2026.
- Already be receiving the homestead exemption on the property.
- File a signed application with your parish assessor, either yourself or through a legal representative.
If you die, your surviving spouse can keep the freeze as long as they are at least 55, or have minor children, and continue to own and occupy the home. The freeze lifts if the property’s value goes up by more than 25% because of new construction or major renovation.
Exemptions for Disabled Veterans
Veterans with a service-connected disability get additional relief layered on top of the standard homestead exemption. The amount depends on the VA disability rating:
- 50% to 69% disability: an extra $2,500 of assessed value exempted beyond the homestead exemption.
- 70% to 99% disability: an extra $4,500 of assessed value exempted beyond the homestead exemption.
- 100% disability: the property is exempt from all ad valorem taxes, with limited exceptions for certain municipal assessments.
At a 100% rating, the result can be a zero-dollar property tax bill on a primary residence. These exemptions apply only to the veteran’s homestead, and you need to file documentation of the VA rating with the parish assessor.
Why the Rate Varies So Much by Parish
Property taxes pay for local services, so what you actually owe depends on where in Louisiana you live. Orleans Parish and East Baton Rouge Parish, with large school systems and extensive city services, are reliably among the highest-millage parishes in the state. Smaller rural parishes with fewer taxing districts tend to run lower.
Property values matter too. A parish with expensive homes and moderate millages can produce a larger bill than a high-millage parish where homes are cheap. Two houses with the same market value in different parishes can generate meaningfully different tax bills. The only reliable way to estimate what you will owe is to pull the combined millage rate for your specific address, not just your parish average.
Appealing an Assessment You Think Is Too High
If you believe your assessed value is too high, you have a specific window to challenge it. Each year, parish assessors open their assessment lists for public inspection for a 15-day period between August 15 and September 15. In Orleans Parish, the inspection window runs from July 15 to August 15. You can review the value on your property and compare it to similar homes nearby.
To formally contest, file a Notice of Appeal Request for Board of Review with your parish assessor during or just after the inspection period. Outside Orleans Parish, you must give the Board of Review at least seven days’ notice before its public hearing, in person, by certified mail, or by fax. The Board hears your case and issues a determination. Either side can appeal from there to the Louisiana Tax Commission.
Successful appeals usually come down to evidence that the assessor’s fair market value is higher than what comparable homes have recently sold for. Recent sales data for similar properties in your neighborhood carries far more weight than a general complaint that the bill feels too high.
When Property Taxes Are Due
Louisiana property taxes are due by December 31 each year. They become delinquent on January 1. Delinquent taxes accrue interest at 1% per month, noncompounding, plus a penalty of up to 5% of the unpaid amount.
Those charges stack up quickly. A $2,000 bill left unpaid for six months picks up $120 in interest alone, before the penalty. If taxes stay unpaid, the parish tax collector can eventually sell a tax lien on the property. Louisiana’s tax sale process was updated by a constitutional amendment that took effect in early 2026, but the core consequence has not changed: long-term nonpayment can cost you the home. Paying by December 31 is the simplest way to avoid both the money and the legal exposure.
