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. 4.7 percent applies everywhere in the parish, levied by the school board at 3 percent, the parish council at 0.7 percent and the law enforcement district at 1 percent. No one rate covers the whole parish: the floor of 9.7 percent is in the balance of the parish outside any municipality and the ceiling of 11 percent is at Oberlin.
