(a) After making the distributions required under §§ 2–604, 2–605, and 2–605.1 of this subtitle, from the remaining income tax revenue from individuals, the Comptroller shall distribute to an unallocated individual revenue account the income tax revenue:
(1) with respect to which an income tax return is not filed; and
(2) that is attributable to:
(i) income tax withheld from salary, wages, or other compensation for personal services under Title 10 of this article; or
(ii) estimated income tax payments by individuals.
(b) (1) In June of each year, from current collections, the Comptroller shall reserve an amount of unallocated revenue that the Comptroller estimates will be claimed on returns and refunded to taxpayers within 3 years of the date the income tax return was due to be filed, and distribute to each county, municipal corporation, and special taxing district a pro rata share of the balance of the unallocated individual income tax revenue.
(2) The Comptroller shall adjust the amount distributed under paragraph (1) of this subsection to a county, municipal corporation, or special taxing district to allow for the proportionate part of tax claim payments for a prior calendar year made after a distribution is made to the county, municipal corporation, or special taxing district for that year.
(c) (1) To compute the pro rata share for a county, the Comptroller shall:
(i) compute the amount equal to the product of multiplying the unallocated individual income tax revenue by a fraction:
1. the numerator of which is the income tax for the county collected for a calendar year; and
2. the denominator of which is the total income tax from individuals collected for that year; and
(ii) reduce the amount computed under item (i) of this paragraph by the pro rata share computed under paragraph (2) of this subsection for municipal corporations and special taxing districts that are located in the county.
(2) To compute the pro rata share for a municipal corporation or special taxing district, the Comptroller shall compute the amount equal to the product of multiplying the pro rata share for a calendar year for the county where the municipal corporation or district is located by a fraction:
(i) the numerator of which is the amount distributed under § 2–607 of this subtitle to that municipal corporation or special taxing district for that year; and
(ii) the denominator of which is the total income tax for that county collected for that year.
