Corporate income tax: credits; ability to claim certain certificated credits against corporate income tax liability; provide for, and repeal Michigan business tax act. Amends secs. 605 & 680 of 1967 PA 281 (MCL 206.605 & 206.680); adds sec. 670 & repeals 2007 PA 36 (MCL 208.1101 - 208.1519). TIE BAR WITH: HB 5293'25

HB 5292 allows corporations with pre-2012 approved tax credits (for job creation or investment) to claim the remaining unused portion against their corporate income tax liability starting in 2026, spread equally over 10 years. To qualify, businesses must maintain at least 95% of their full-time jobs (35+ hours weekly with payroll taxes withheld) as of September 30, 2025, each tax year. The bill also repeals Michigan’s Business Tax Act (2007 PA 36) for tax years beginning after December 31, 2025, ending that separate tax system. This directly affects corporations holding unused credits from older economic development programs.
