Such budget shall be a tentative work program for the coming biennium, shall contain a full and itemized report of the expenditures from appropriations made by the previous Legislature and the items which the Governor deems worthy of consideration for the coming biennium, for the respective departments, offices, and institutions, and for all other purposes, and shall contain the estimated revenue from taxation, the estimated revenue from sources other than taxation, an estimate of the amount required to be raised by taxation and the sales and income tax rates necessary to raise such amount, the revenue foregone by operation of laws in effect at the time of such report granting tax expenditures and reduced tax liabilities as identified in the reports required by sections 77-5731 and 77-6837, and recommendations as to deficiency funding requirements pursuant to section 81-126.
