In counties of more than 1,000,000 inhabitants, a county board may levy and collect, in odd numbered years, a tax of not to exceed .05% of the value, as equalized or assessed by the Department of Revenue, of all the taxable property in the county, for the expense of conducting elections and maintaining a system of permanent registration of voters. Such tax shall not be included within any statutory limitation of rate or amount for other county purposes, but shall be excluded therefrom and be in addition thereto and in excess thereof; provided that this tax shall not be levied or collected on property situated within the jurisdiction of any municipal board of election commissioners.
Beginning with calendar year 1986 and annually thereafter, any county with less than 1,000,000 inhabitants shall pay over to any municipal board of election commissioners in the county, for the expense of conducting elections and maintaining a system of permanent registration of voters, an amount at least equal to the proceeds of the tax collected on property situated within the jurisdiction of that board under this Section during calendar year 1985; provided, however, such amount shall be increased or decreased annually in proportion to any increase or decrease in the equalized assessed valuation of such municipality. Such amount shall be payable from the tax levied and collected under Section 5-1024.
