Advanced Industrial Manufacturing Zones Act


As a means to develop or redevelop areas identified by the port authority board of commissioners, this program establishes the Port Authority AIM Zone Fund consisting of 50% of the state withholding tax from new jobs within the zone after development or redevelopment has begun.

Do I Qualify?

To be eligible for the retention of tax withholdings there must be an increase in the number of full-time employees located at the project facility that exceeds the project facility base employment less any decrease in the number of full-time employees at related facilities below the related facility base employment. No job that was created prior to the date of the notice of intent shall be deemed a new job. An employee that spends less than fifty percent of the employee’s work time at the facility is still considered to be located at a facility if the employee receives his or her directions and control from that facility, is on the facility’s payroll, one hundred percent of the employee’s income from such employment is Missouri income and the employee is paid at or above the state average wage.

A related facility is a facility operated by a company or a related company prior to the establishment of the AIM Zone in question located within any port district, as defined under section 68.015, which is directly related to the operations of the facility within the new AIM Zone.
