Commencing in the fiscal year ending June 30, 2018:

(A) Such itemization shall include the estimate for each major component of the personal income tax imposed pursuant to chapter 229 as follows: Withholding payments and estimated and final payments; and

(B) Commencing with the consensus revenue estimate or revised consensus revenue estimate maintained or revised not later than November 10, 2017, each consensus revenue estimate or revised consensus revenue estimate shall include a line item designated as the volatility adjustment that reflects the amount of the estimated transfer pursuant to subsection (a) of section 4-30a .

(2) The statement of estimated revenue applicable to each such fund shall include, for any fiscal year, an estimate of total revenue with respect to such fund, which amount shall be reduced by (A) an estimate of total refunds of taxes to be paid from such revenue in accordance with the authorization in section 12-39f , and (B) an estimate of total refunds of payments to be paid from such revenue in accordance with the provisions of sections 3-70a and 4-37 .

(3) The total estimated revenue for each fund, as adjusted in accordance with this section, shall not be less than the total net appropriations made from each fund plus, for the fiscal year ending June 30, 2014, and each fiscal year thereafter, the amount necessary to extinguish any unassigned negative balance in each budgeted fund as addressed in the most recently issued annual report of the Comptroller published in accordance with section 3-115 . On or before July first of each fiscal year, the joint standing committee of the General Assembly having cognizance of matters relating to state finance, revenue and bonding shall, if any revisions in such estimates are required by virtue of legislative amendments to the revenue measures proposed by said committee, changes in conditions or receipt of new information since the original estimate was supplied, meet and revise such estimates and, through its cochairpersons, report to the Comptroller any such revisions.

(c) If the state budget act passed by the legislature for funding the expenses of operations of the state government in the ensuing biennium or making adjustments to a previously adopted biennial budget contains state-wide budgeted reductions not allocated by a budgeted agency, such act shall specify the amount of such budgeted reductions to be achieved in each branch of state government.
