(a) On and after October 1, 1978, all taxable property within this state, not exempt by law, shall be divided into the following classes for the purposes of ad valorem taxation:
Class I. All property of utilities used in the business of such utilities.
Class II. All property not otherwise classified.
Class III. All agricultural, forest and single-family owner-occupied residential property, and historic buildings and sites.
Class IV. All private passenger automobiles and motor trucks of the type commonly known as “pickups” or “pickup trucks” owned and operated by an individual for personal or private use and not for hire, rent or compensation.
(b) With respect to ad valorem taxes levied by the state, all taxable property shall be forever taxed at the same rate. On and after October 1, 1978, such property shall be assessed for ad valorem tax purposes according to the classes thereof as herein defined at the following ratios of assessed value to the fair and reasonable market value (except as otherwise provided in subsection (j) hereof) of such property:
Class I. 30 per centum.
Class II. 20 per centum.
Class III. 10 per centum.
Class IV. 15 per centum.
(c) With respect to ad valorem taxes levied by counties, municipalities or other taxing authorities, all taxable property shall be forever taxed at the same rate. On and after October 1, 1978, such property shall be assessed for ad valorem tax purposes according to the classes of property defined in subsection (a) hereof and at the same ratios of assessed value to the fair and reasonable market value thereof as fixed in subsection (b) hereof, except as otherwise provided in subsection (j) hereof and this subsection (such ratios being herein called “assessment ratios”). In connection with the ad valorem taxes that a county, municipality or other taxing authority is authorized or required to levy and collect pursuant to any provision of this Constitution, for the ad valorem tax year beginning October 1, 1978, any such taxing authority may, subject to criteria established by act of the legislature, by resolution of the governing body of that taxing authority, at any time not later than September 30, 1979, increase or decrease the assessment ratio applicable to any class of taxable property, such increase or decrease to be effective for ad valorem tax years beginning on and after October 1, 1978. If (1) a county, municipality or other taxing authority adjusts an assessment ratio pursuant to the preceding sentence and (2) the receipts from all ad valorem taxes levied by or with respect to such taxing authority during the ad valorem tax year beginning October 1, 1978, exceed by more than five percent, or are less than 95 percent of, the receipts from such ad valorem taxes for the ad valorem tax year beginning October 1, 1977, then at any time not later than September 30, 1980, for ad valorem tax years beginning on and after October 1, 1979, the taxing authority may, subject to criteria established by act of the legislature, by resolution of the governing body of that taxing authority, adjust any assessment ratio applicable to any class of taxable property. On and after October 1, 1979, the governing body of any county, municipality or other taxing authority may, subject to criteria established by act of the legislature, at any time increase or decrease the assessment ratio applicable to any class of taxable property; provided, that any proposed adjustment to an assessment ratio to be made pursuant to this sentence, whether an increase or a decrease, shall have been (1) proposed by the governing body of the taxing authority after a public hearing on such proposal, (2) thereafter approved by an act of the legislature, and (3) subsequently approved by a majority vote of the qualified electors residing in the taxing authority who vote on the proposal at a special election called and held in accordance with the law governing special elections. No decrease in an assessment ratio pursuant to this subsection (c) shall be permitted with respect to either of the ad valorem tax years beginning October 1, 1978, and October 1, 1979, if such county, municipality or other taxing authority has increased any millage rate under subsection (e) of this section with respect to such ad valorem tax year. The legislature shall enact general laws applicable to all counties, municipalities and other taxing authorities regulating and establishing criteria for the exercise of the powers granted such taxing authorities to adjust assessment ratios as hereinabove provided. Such assessment ratios as herein authorized may vary among taxing authorities so long as each such assessment ratio is uniform within a taxing authority. Any decrease in any assessment ratio pursuant to this subsection shall not jeopardize the payment of any bonded indebtedness secured by any tax levied by the taxing authority decreasing the assessment ratio. Any action authorized by this subsection to be taken by a taxing authority, or the governing body thereof, shall, other than in the case of a municipality, be taken by resolution of the governing body of the county in which such taxing authority is located acting on behalf of such taxing authority.
(d) With respect to ad valorem taxes levied by the state or by any county, municipality or other taxing authority, no class of taxable property shall have an assessment ratio of less than five per centum nor more than 35 per centum.
(e) A county, municipality or other taxing authority may decrease any ad valorem tax rate at any time, provided such decrease shall not jeopardize the payment of any bonded indebtedness secured by such tax. For the ad valorem tax year beginning October 1, 1978, when the tax assessor of each county shall complete the assembly of the assessment book for his county for that ad valorem tax year and the computation of ad valorem taxes that will be paid upon such assessment, he shall certify to each authority within his county that levies an ad valorem tax the amount of ad valorem tax that will be produced by every levy in that ad valorem tax year but excluding for this purpose any assessment of new taxable property not previously subject to taxation (except “escaped” property as defined by law) added to the tax rolls of such county for the ad valorem tax year in which such certification is made that was not included on the tax rolls for the next preceding ad valorem tax year. Any county, municipality or other taxing authority, at any time not later than September 30, 1979, may increase the rate at which any ad valorem tax is levied by or with respect to that taxing authority above the limit otherwise provided in this Constitution, provided that the amount of the above-described certification of anticipated tax receipts with respect to such tax is less than 120 percent of the actual receipts from such tax for the ad valorem tax year beginning October 1, 1977, such increase to be effective for ad valorem tax years beginning on and after October 1, 1978; provided, that any such millage increase shall not exceed in mills the total of (i) the number of additional mills that is necessary, when added to the millage rate imposed with respect to such tax on each dollar of taxable property situated in the taxing authority for the ad valorem tax year beginning October 1, 1977, to produce revenue that is not less than and that is substantially equal to that received by the taxing authority with respect to such tax during such immediately preceding ad valorem tax year, plus (ii) a number of additional mills equal to 20 percent of the total mills imposed by that taxing authority with respect to such tax on each dollar of taxable property situated in the taxing authority for the ad valorem tax year beginning October 1, 1977. If, for the ad valorem tax year beginning October 1, 1978, the receipts from any ad valorem tax with respect to which any millage rate has been increased pursuant to the immediately preceding sentence are less than 95 percent of the receipts from such ad valorem tax for the ad valorem tax year beginning October 1, 1977, then at any time not later than September 30, 1980, the taxing authority may increase any millage rate with respect to such ad valorem tax in the manner provided in the immediately preceding sentence, such increase to be effective for ad valorem tax years beginning on and after October 1, 1979. It is further provided that all millage adjustments shall be made in increments of not less than one tenth () mill.
(f) On and after October 1, 1979, any county, municipality or other taxing authority may at any time increase the rate at which any ad valorem tax is levied above the limit otherwise provided in this Constitution; provided, that the proposed increase to be made pursuant to this subsection shall have been (1) proposed by the governing body of the taxing authority after a public hearing on such proposal, (2) thereafter approved by an act of the legislature, and (3) subsequently approved by a majority vote of the qualified electors residing in the taxing authority who vote on the proposal at a special election called and held in accordance with the law governing special elections. Any adjustments or other actions authorized to be made or taken pursuant to this subsection and subsection (e) hereof shall be made or taken by resolution of the governing body of such taxing authority, or if there is no such governing body and in the case of a taxing authority other than a municipality, by resolution of the governing body of the county in which such taxing authority is located acting on behalf of such taxing authority. The provisions of subsections (c), (e) and (f) of this section shall not apply to ad valorem taxes levied by the state.
(g) The legislature is authorized to enact legislation to implement the provisions of this section and may provide for exemptions from taxation; provided, that unless otherwise expressly provided, no amendment to this section shall be construed to repeal any statutory exemption existing on the effective date of any such amendment hereto.
(h) Wherever any constitutional provision or statute provides for, limits or measures the power or authority of any county, municipality or other taxing authority to levy taxes, borrow money or incur indebtedness in relation to the assessment of property therein for state taxes or for state and county taxes, such provision shall mean as assessed for county or municipal taxes, as the case may be.
(i) Except as otherwise provided in this Constitution, including any amendment thereto whenever adopted with respect to taxable property located in the city of Mountain Brook, the city of Vestavia Hills, or the city of Huntsville, the amount of ad valorem taxes payable to the state and to all counties, municipalities and other taxing authorities with respect to any item of taxable property described as Class I property shall never exceed 2 percent of the fair and reasonable market value of such taxable property in any one ad valorem tax year, such amount with respect to any item of Class II property shall never exceed 1 percent of the fair and reasonable market value of such taxable property in any one ad valorem tax year, such amount with respect to any item of Class IV property shall never exceed 1 percent of the fair and reasonable market value of such taxable property in any one ad valorem tax year, and such amount with respect to any item of Class III property shall never exceed 1 percent of the fair and reasonable market value of such taxable property in any one ad valorem tax year. Whenever the total amount of ad valorem property taxes otherwise payable by any taxpayer with respect to any item of taxable property shall exceed in any one ad valorem tax year the maximum amount of such taxes permitted by this section, such amount of taxes shall be reduced by subtracting that amount of tax due that is in excess of the amount of tax otherwise permissible under the Constitution. In connection with the taxation of any item of taxable property, the amount of tax to be subtracted with respect to each authority levying and collecting any ad valorem property tax shall be in the same proportion to the total amount of tax to be subtracted that the total number of mills on each dollar of taxable property situated in the taxing authority levied by such taxing authority bears to the total number of mills on each dollar of taxable property situated in the taxing authority levied by all taxing authorities with respect to such item of taxable property. Before sending to any taxpayer any notice relating to the collection of ad valorem taxes, the tax collector in each county shall determine whether any portion of the amount of ad valorem property tax otherwise due with respect to any item of taxable property shall be subtracted pursuant to the provisions of this subsection and shall apportion the amount to be subtracted in accordance with the provisions of this subsection.
(j) Notwithstanding any other provision of this section, on and after October 1, 1978, taxable property defined in subsection (a) hereof as Class III property shall, upon application by the owner of such property, be assessed at the ratio of assessed value to the current use value of such taxable property and not the fair and reasonable market value of such property. The legislature may enact laws uniformly applicable to the state and all counties, municipalities and other taxing authorities establishing criteria and procedures for the determination of the current use value of any eligible taxable property and procedures for qualifying such property for assessment at its current use value. The legislature may also enact laws uniformly applicable to the state and all counties, municipalities and other taxing authorities providing for the ad valorem taxation of any taxable property ceasing to qualify for current use valuation; provided, however, that any additional tax on taxable property ceasing to qualify for current use valuation shall not apply to more than the three ad valorem tax years immediately preceding such cessation of qualification (including as one such year the year in which cessation of qualification occurs).
(k) The following property shall be exempt from all ad valorem taxation: the real and personal property of the state, counties and municipalities and property devoted exclusively to religious, educational or charitable purposes, household and kitchen furniture, all farm tractors, all farming implements when used exclusively in connection with agricultural property and all stocks of goods, wares and merchandise.
(l) (l) Notwithstanding the other provisions of this section, with respect to the costs of reappraisal incident to the state-wide reappraisal of property heretofore authorized by the legislature, each county, municipality or other taxing authority for ad valorem tax years beginning on and after October 1, 1978, may impose and levy an additional ad valorem tax of not more than two mills on all taxable property located in the taxing authority in order to reimburse itself for its payment of such costs of reappraisal or to pay any unpaid costs or its pro rata share of such unpaid costs of reappraisal. The taxes provided for in this subsection, or any pro rata part thereof, shall terminate at the end of the ad valorem tax year in which sufficient funds are received from the taxes to pay in full the said reappraisal costs and any receipts from such taxes that are received during the ad valorem tax year of their termination that are not needed for the purposes specified herein may be used by the taxing authority levying the tax for general purposes of the taxing authority. The taxes authorized in this subsection shall not exceed in the aggregate, with respect to any item of taxable property located in the taxing authority, a total of two mills for all such taxes levied by all taxing authorities in a county and not two mills for each taxing authority in a county. If more than one such taxing authority in a county has paid or owes all or a portion of its reappraisal costs, such two mills shall be prorated among such taxing authorities in the county as they may agree, or if they cannot agree, in the percentage which each such taxing authority’s costs of reappraisal bear to the total costs of reappraisal of all taxing authorities in the county. The provisions of this subsection shall apply only to the costs incurred by a taxing authority incident to the statewide reappraisal of property heretofore authorized by the legislature, the amount of which costs shall be certified by the department of revenue, and shall not be applicable to any future reappraisals that may be required by law.
(m) If any portion of this section should be declared invalid by any court of competent jurisdiction, such invalidity shall not affect the validity of any of the remaining portions of this section, which shall continue effective.
