Sales tax in Ascension Parish, Louisiana

By Brent Chudoba, editor Updated

There is no single sales tax rate in Ascension Parish. It runs from 9.5% to 11% depending on the exact address, because cities and special districts inside the county levy their own on top of the 5% state rate. The 5% state rate applies everywhere in the county; everything above that depends on where you are standing. These rates were read from Louisiana's own published schedule and checked on September 9, 2026.

Why the rate here is not the whole story

Louisiana charges 5 percent statewide, and every local sales tax is levied and collected locally rather than by the state, by the parish school board, the parish governing authority, the sheriff's law enforcement district, municipalities and economic development districts, so the parish line is not the tax boundary. 2 percent applies everywhere in the parish, levied by the school board at 2 percent. No one rate covers the whole parish: the floor of 9.5 percent is at East Ascension outside Gonzales or Sorrento and the ceiling of 11 percent is at Donaldsonville-Annexation Area. That ceiling applies only inside a single development or annexation district rather than across a whole town, so it must not be read as the rate for the surrounding area.

How do I find the exact rate for an address in Ascension Parish?

Use Louisiana's own address lookup. In Ascension Parish the rate depends on the address, anywhere from 9.5% to 11%.

Who has to collect sales tax in Ascension Parish?
