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. The whole parish files as a single jurisdiction and the local rate of 5.25 percent applies everywhere in it. Every jurisdiction the table lists comes to the same 10.25 percent.
