MI HB4905

Extends the data center equipment tax exemption deadline from December 31, 2035 to December 31, 2050 for qualified data centers and colocated businesses.

Creates a new "enterprise data center" category exempt from use tax through December 31, 2050 (or 2065 for brownfield/former power plant sites) if the facility meets requirements including $250 million minimum capital investment and $1 million annual compensation to qualified employees earning 120% of county average wage.

Establishes a certificate application and approval process through the Michigan Strategic Fund with 120-day review period; requires annual reporting by qualified entities and allows certificate revocation if enterprise data center criteria are not met.

Clarifies that job creation requirements in subsections (2) and (3) exclude jobs held by "qualified employees" (those earning 120% of county average wage), and transfers reporting responsibility from the Department of Talent and Economic Development to the Michigan Strategic Fund.

Adds detailed definitions for "enterprise data center," "certificate," "qualified entity," and "qualified employee," and expands "data center equipment" to include construction materials and infrastructure used for enterprise data center facilities.
