    "Misallocation" means tax paid by the taxpayer and allocated to one unit of local government that should have been allocated to a different unit of local government. This includes misallocations discovered by a unit of local government through the tax location verification process under Section 8-11-16 of the Illinois Municipal Code and misallocations discovered by the Department other than through an audit of the taxpayer. "Misallocation" does not, however, include any amount reported by a taxpayer in an amended return or any amount discovered in an audit of the taxpayer by the Department or discovered in an audit of the taxpayer by a qualified practitioner under Article 10 of this Act. "Misallocation" also does not include amounts overpaid by the taxpayer and therefore not owed to any unit of local government, nor amounts underpaid by the taxpayer and therefore not previously allocated to any unit of local government.
    "Monitoring disbursements" means keeping track of payments from the Department by a municipality, county, or third party for the limited purpose of tracking previous misallocations.
    "Third party" means a person, partnership, corporation, or other entity or individual registered to do business in Illinois who contracts with a municipality or county to review financial information related to the disbursement of local taxes by the Department to the municipality or county.
