Answers to common questions about buying a home in Ascension Parish.
There is no single property tax rate for Ascension Parish. The 0.54% figure commonly quoted is a county-wide median: the median annual property tax paid ($1,519) divided by the median home value ($279,600), from 2024 US Census ACS 5-year estimates. It is a statistic describing the county, not a rate levied on any particular property. Your own bill depends on your assessed value, the millage set by your overlapping taxing districts, any homestead or senior exemptions you qualify for, and special assessments. One thing to watch: the median reflects taxes actually paid by current owners, many of whom hold homestead exemptions and assessment caps, so a new buyer paying today's market price often pays more than 0.54% of the purchase price.
Louisiana's combined real estate transfer tax is approximately 0.00% of the purchase price. On the median Ascension Parish home value of $279,600, this adds roughly $0 at closing. No statewide transfer tax. Orleans Parish levies a flat Documentary Transaction Tax of $325 (first 25 pages) + $100/page thereafter, max $2,525, seller-paid. Other parishes: no transfer tax.
