((a)) ** .—** If there is in a State an Indian tribe or Alaskan native  village having a recognized governing body carrying out substantial governmental duties and powers, the Secretary shall allocate to the tribe or village, out of the amount allocated to the State under section 6704, an amount bearing the same ratio to the amount allocated to the State as the population of the tribe or village bears to the population of the State. The Secretary shall allocate amounts under this subsection to Indian tribes and Alaskan native  villages in a State before allocating amounts to units of general local government in the State under subsection (c). For the payment period beginning , the Secretary shall use as the population of each Indian tribe or Alaskan native  village the population for 1991 as reported by the Bureau of Indian Affairs in the publication Indian Service Population and Labor Force Estimates (January 1991). In addition to uses authorized under section 6701(a)(2), amounts allocated under this subsection and paid to an Indian tribe or Alaskan native  village under this chapter may be used for renovating or building prisons or other correctional facilities.

((b)) ** .—** If there is in a State a unit of general local government that has been incorporated since the date of the collection of the data used by the Secretary in making allocations pursuant to sections 6704 through 6706 and 6708, the Secretary shall allocate to this newly incorporated local government, out of the amount allocated to the State under section 6704, an amount bearing the same ratio to the amount allocated to the State as the population of the newly incorporated local government bears to the population of the State. If there is in the State a unit of general local government that has been annexed since the date of the collection of the data used by the Secretary in making allocations pursuant to sections 6704 through 6706 and 6708, the Secretary shall pay the amount that would have been allocated to this local government to the unit of general local government that annexed it.

((c))

((1)) ** .—** The Secretary shall allocate among the units of general local government in a State (other than units receiving allocations under subsection (a)) the amount allocated to the State under section 6704 (as that amount is reduced by allocations under subsection (a)). Of the amount to be allocated, the Secretary shall allocate a portion equal to ½ of such amount in accordance with section 6706(1), and shall allocate a portion equal to ½ of such amount in accordance with section 6706(2). A unit of general local government shall receive an amount equal to the sum of amounts allocated to the unit from each portion.

((2)) ** .—** From each portion to be allocated to units of local government in a State under paragraph (1), the Secretary shall allocate to a unit an amount bearing the same ratio to the funds to be allocated as—

((A)) the population of the unit, multiplied by the general tax effort factor of the unit (determined under paragraph (3)), multiplied by the income gap of the unit (determined under paragraph (4)), bears to

((B)) the sum of the products determined under subparagraph (A) for all units in the State for which the income gap for that portion under paragraph (4) is greater than zero.

((3)) ** .—**

((A)) Except as provided in subparagraph (C), the general tax effort factor of a unit of general local government for a payment period is—

((VI)) If the amount of adjusted taxes is less than zero, the amount of adjusted tax shall be deemed to be zero.

((VII)) If the amount of adjusted taxes exceeds the amount of total taxes, the amount of adjusted taxes is deemed to equal the amount of total taxes.

((ii)) The Secretary shall, for purposes of clause (i), include that part of sales taxes transferred to a unit of general local government that are imposed by a county government in the geographic area of which is located the unit of general local government as taxes imposed by the unit for public purposes if—

((I)) the county government transfers any part of the revenue from the taxes to the unit of general local government without specifying the purpose for which the unit of general local government may expend the revenue; and

((II)) the chief executive officer of the State notifies the Secretary that the taxes satisfy the requirements of this clause.

((iii)) The adjusted taxes of a unit of general local government shall not exceed the maximum allowable adjusted taxes for that unit.

((iv)) The maximum allowable adjusted taxes for a unit of general local government is the allowable adjusted taxes of the unit minus the excess adjusted taxes of the unit.

((v)) The allowable adjusted taxes of a unit of general government is the greater of—

((I)) the amount equal to 2.5, multiplied by the per capita adjusted taxes of all units of general local government of the same type in the State, multiplied by the population of the unit; or

((II)) the amount equal to the population of the unit, multiplied by the sum of the adjusted taxes of all units of municipal local government in the State, divided by the sum of the populations of all the units of municipal local government in the State.

((vi)) The excess adjusted taxes of a unit of general local government is the amount equal to—

((I)) the adjusted taxes of the unit, minus

((II)) 1.5 multiplied by the allowable adjusted taxes of the unit;

((vii)) For purposes of this subparagraph—

((I)) the term “per capita adjusted taxes of all units of general local government of the same type” means the sum of the adjusted taxes of all units of general local government of the same type divided by the sum of the populations of all units of general local government of the same type; and

((II)) the term “units of general local government of the same type” means all townships if the unit of general local government is a township, all municipalities if the unit of general local government is a municipality, all counties if the unit of general local government is a county, or all unified city/county governments if the unit of general local government is a unified city/county government.

((4)) ** .—**

((A)) Except as provided in subparagraph (B), the income gap of a unit of general local government is—

((d)) ** .—** If the Secretary decides that information available for a unit of general local government with a population below a number (of not more than 500) prescribed by the Secretary is inadequate, the Secretary may allocate to the unit, in lieu of any allocation under subsection (b) for a payment period, an amount bearing the same ratio to the total amount to be allocated under subsection (b) for the period for all units of general local government in the State as the population of the unit bears to the population of all units in the State.
