Louisiana Constitution of 1974 Art. VII, § 3. Collection of Taxes

(B)(1) Notwithstanding any contrary provision of this constitution, sales and use taxes levied by political subdivisions shall be collected by a single collector for each parish. On or before July 1, 1992, all political subdivisions within each parish which levy a sales and use tax shall agree between and among themselves to provide for the collection of such taxes by a single collector or a central collection commission. The legislature, by general law, shall provide for the collection of sales and use taxes, levied by political subdivisions, by a central collection commission in those parishes where a single collector or a central collection commission has not been established by July 1, 1992.

(2) The legislature, by local law enacted by two-thirds of the elected members of each house of the legislature, may establish an alternate method of providing for a single collector or a central collection commission in each parish.

(3) Except when authorized by the unanimous agreement of all political subdivisions levying a sales and use tax within a parish, only those political subdivisions levying a sales and use tax shall be authorized to act as the single collector or participate on any commission established for the collection of such taxes.

(4) The legislature shall provide for the prompt remittance to the political subdivisions identified on the taxpayers' returns of funds collected pursuant to the provisions of this Paragraph by a single collector or under any other centralized collection arrangement.

(5) The provisions of this Paragraph shall not apply in those parishes which have a single collector or a centralized collection arrangement as of July 1, 1992.
