Expires the authority to impose a property tax relief rate under the LIT and repeals the levy freeze rate. Provides that, in order to continue to impose an expenditure tax rate after 2027, each county must adopt a new ordinance on or before October 1, 2027, to impose the rate. Provides that, for counties that fail to adopt an ordinance to renew an existing expenditure tax rate in 2027, the expenditure tax rate for the county in 2028 shall be the minimum tax rate necessary for existing debt service. Specifies that this does not prevent the county from renewing, imposing, or modifying an expenditure tax rate in subsequent years.
