Section 30 ILCS 805/6 - State Reimbursement to Local Government For Increased Costs Arising From Certain Mandates(a) Any increased costs accruing to local governments as a direct result of mandates dealing with the organization and structure of local government or due process mandates, as defined in subsections (c) and (d), respectively, of Section 3 above, are not reimbursable by the State.(b) At least 50%, but not more than 100% of the increase in costs of a local government directly attributable to a service mandate as defined in subsection (f) of Section 3 enacted by the General Assembly or established administratively after the effective date of this Act shall be reimbursed by the State unless there is in existence at the time of such enactment a program of State aid for the service affected by the mandate whereunder the non-local share for any participating local government is 50% or greater and where the increased costs arising under the mandate constitute allowable expenditures under the aid program. Where all or part of the increased costs are met through federal or other external aid, only the net increase to the local government shall be included in the base against which the amount of State reimbursement is to be computed.(c) 100% of the loss in revenue of a local government directly attributable to a mandated classification or exemption of property for purposes of ad valorem real property taxation enacted after the effective date of this Act shall be reimbursed by the State. The loss of revenue does not include potential revenue from property of a type which was not being assessed and taxed on January 1, 1980.(d) Except for a State mandate that affects personnel qualifications for local employees, the salaries and wages of which are financed under a State program, and except as provided in subsection (e) below, any personnel mandate as defined in subsection (h) of Section 3 above enacted by the General Assembly or established administratively after the effective date of this Act shall be reimbursed by the State to the extent of increased costs incurred by local governments directly attributable to such mandate.(e) All of the increased costs of a local government directly attributable to a mandated increase in public employee retirement benefits which is enacted after the effective date of this Act and which has the effect of elevating retirement benefits of local government employees shall be reimbursed by the State; except that any increased costs of a local government attributable to Public Act 83-152, 83-374, 83-375, 83-528, 83-558, 83-661, 83-664, 83-737, 83-772, 83-773, 83-780, 83-792, 83-793, 83-802, 83-810, 83-812, 83-823, 83-827 or 83-869 are not reimbursable by the State.(f) After the effective date of this Act, any bill filed and any amended bill that creates or enlarges a State mandate of the type specified in subsections (f), (g) and (h) of Section 3, shall have provided and identified for it an appropriation of an amount necessary to provide the reimbursement specified above unless a statement, stating the specific reasons for such exclusion is set out in the bill or amendment as provided in subsection (a) of Section 8.(g) If a local government or combination of local governments has been providing a service at its option which is subsequently mandated by the State, the State shall pay them for the subsequent costs of such program and the local government or governments shall proportionately reduce its or their property tax extensions by the amount that the State payment replaces property tax revenues which were being expended on such service. However, for purposes of calculating a school district's State aid, no district's operating tax rate shall be decreased as a result of reimbursement under this Act.(h) Any increased costs accruing to a local government as a direct result of the requirements of the Steel Products Procurement Act are not reimbursable by the State.
