La. Revenue and Taxation § 47:1968
The shares shall be assessed at the per centum of their valuation made by the assessing authorities to the shareholders at the domicile or location of the bank, banking company, firm, association or corporation, who appear as such upon the books, regardless of the domicile of the shareholders and regardless of any transfer not registered or entered upon its books. When any bank, banking company, firm, association or corporation engaged in the banking business operates a branch bank or banks, banking office or banking offices in any parish or parishes other than the parish of its legal domicile, its assessment shall be divided for state and local purposes, and the number of shares, or fractions thereof, to be assessed in each parish in which such bank and its branches are maintained shall be determined by the proportion which the capital stock assigned to each bank and branch of such bank shall bear to the whole capital stock; provided that in the event, for any reason it should be held by the courts that any portion of this Section is unconstitutional, such invalidity shall not affect the enforcement of the remainder of this Section, and all such banks shall then be assessed at the location or domicile of the main bank in the same manner as banks without branches for current and back taxes.
