The legislature shall have the power to levy and collect taxes for state purposes on net incomes from whatever source derived within this state, including the incomes derived from salaries, fees and compensation paid from the state, county, municipality, and any agency or creature thereof, for the calendar year, 1933, and thereafter and to designate and define the incomes to be taxed and to fix the rates of taxes, provided that the rate shall not exceed 5 percent nor 3 percent on corporations. Income shall not be deemed property for purposes of ad valorem taxes. From net income an exemption of not less than fifteen hundred dollars ($1,500.00) shall be allowed to unmarried persons and an exemption of not less than three thousand dollars ($3,000.00) shall be allowed to the head of a family, provided that only one exemption shall be allowed to husband and wife where they are living together and make separate returns for income tax. An exemption of not less than three hundred dollars ($300.00) shall be allowed for each dependent member of the family of an income tax payer under the age of 18 years. The legislature shall reduce the ad valorem tax from time to time when and to such an amount as the revenue derived from the income tax will justify. In the event the legislature levies an income tax, such tax must be levied upon the salaries, income, fees, or other compensation of state, county and municipal officers and employees, on the same basis as such income taxes are levied upon other persons. [Amendment No. 25; Amendment No. 61, below, repeals all provisions in conflict, and Amendment Nos. 212 and 662 change the rate of the corporate income tax.]

Disposition of income tax; exemption of homesteads from state ad valorem tax. Section A. The entire proceeds of the income tax in the treasury of the state of Alabama on September 30, 1947, including cash and investments and the interest thereon, shall be used for the following purposes and in the following manner: lst. The sum of $12,249,860.00 shall be and is hereby set aside and shall be and is hereby constituted an irrevocable trust fund for the purpose of paying the principal of and interest on the bonds issued by the state of Alabama commonly known as "income tax bonds," being the warrant refunding bonds issued to fund the floating debt existing October 1, 1932, which bonds were issued under the authority of Act No. 14 approved February 5, 1935 [Acts 1935, p, 27], and Act No. 50 approved February 8, 1935 [Acts 1935, p. 118]. 2nd. An amount (approximately $6,700,000.00) which, when added to the sinking fund (approximately $1,857,000.00) heretofore created to pay the bonds issued by the state of Alabama, commonly known as the "old bonded debt" and as "carpet bag bonds" together with the interest on said sinking fund accrued on September 30, 1947, shall equal the principal of said bonds in the sum of $8,557,000.00, shall be and is hereby set aside, and together with said sinking fund and the interest thereon, shall be and is hereby constituted an irrevocable trust fund for the purpose of paying the principal of said bonds upon their maturity, said bonds being the class A renewal bonds, class C renewal bonds and funding renewal bonds. That both of the irrevocable trust funds herein created shall be invested in United States government securities by the treasurer of the state of Alabama with the approval of the governor. 3rd. The residue shall be paid over to the building commission created by Act 128 of 1945 General Acts [p. 116] to be expended by said building commission for capital outlay only for educational purposes, provided, however, that not more than twelve per centum of such amount shall be allocated to the institutions of higher learning including the state teachers colleges, and not less than eighty-eight per centum shall be allocated to county and city boards of education on an actual teacher unit basis in accordance with the minimum school program.

Section B. Beginning October 1, 1947, and thereafter, all net proceeds of such tax, plus the earnings from investment of the trust funds, must be used only in the manner and in the order following: (1) To replace the revenue lost to the several funds of the state by reason of the exemption of homesteads from the state ad valorem tax. All homesteads in Alabama are hereby declared to be exempt from all state ad valorem tax to the extent of at least $2,000.00 in assessed value and a sufficient amount is hereby appropriated from the proceeds of the income tax in each fiscal year to replace the revenue lost to the several funds of the state by reason of the homestead exemption herein declared; (2) The residue shall be placed in the state treasury to the credit of the Alabama special education trust fund to be used for the payment of public school teachers salaries only.

Section C. This amendment supersedes the provisions of amendment XXV [25] (article XXII) relating to the disposition of the income tax proceeds insofar as the same are in conflict herewith. All laws relating to the income tax, not in conflict herewith and valid on the date of the ratification of this amendment, are hereby validated and confirmed. The provisions hereof with respect to the creation of funds and the use thereof are declared to be self-executing. [Amendment No. 61]

State tax on net income of corporations. The legislature shall have power to levy and provide for the collection of taxes for state purposes on net taxable income of corporations, from whatever source derived, for the calendar year 1963, or for any fiscal year beginning in the calendar year 1963, and each year thereafter, at a rate not exceeding five percent. However, the rate shall be six and one-half percent on taxable income of corporations for the calendar year 2001, or for any fiscal year beginning in the calendar year 2001, and each year thereafter.  All federal income taxes paid or accrued within the taxable year by corporations shall always be deductible in computing income taxable under the income tax laws of this state, provided that in the case of foreign corporations the amount of federal income tax deductible shall be in proportion to income derived from sources within Alabama, to be determined in accordance with such laws as the legislature may enact. The increase in the corporate income tax rate to six and one-half percent provided by this amendment shall be self-executing and shall require no enabling legislation. [Amendment No. 212, as amended by Amendment No. 662]

Deduction of federal income tax from gross income when computing state income tax. In computing net income for state income tax purposes for the calendar year 1965 and each year thereafter, a resident individual taxpayer shall be allowed to deduct from his gross income the amount of federal income tax paid or accrued within the taxable year. A nonresident individual income taxpayer shall be allowed to deduct only that amount of federal income tax paid or accrued in the taxable year on income received from sources within the state. [Amendment No. 225]
