If a library is subject to the Property Tax Extension Limitation Law in the Property Tax Code and its tax levy for library purposes has been lowered to a rate of less than .13%, the library will qualify for this grant if the library levied a tax for library purposes that met the requirements for this grant in the previous year and if the tax levied for library purposes in the current year produces tax revenue for the library that is an increase over the previous year's extension of 5% or the percentage increase in the Consumer Price Index, whichever is less, and the tax revenue produced by this levy is less than $17.50 per capita in property tax revenue from property taxes for the Fiscal Year 2025 and thereafter. In this case, the State Librarian is authorized to make an equalization grant equivalent to the difference between the amount of tax revenue obtained from the current levy and an annual income of $17.50 per capita for grants made in Fiscal Year 2025 and thereafter. If moneys appropriated for grants under this Section are not sufficient, then the State Librarian shall reduce the per capita amount of the grants so that the qualifying public libraries receive the same amount per capita, but in no event shall the grant be less than equivalent to the difference between the amount of the tax revenue obtained from the current levy and an annual income of $4.25 per capita. If a library receiving an equalization grant reduces its tax levy below the amount levied at the time the original application is approved, it shall be ineligible to receive further equalization grants.
