MI SB1163

Amends the Michigan Business Tax Act to allow certain taxpayers with certificated credits to elect filing under the business tax instead of the corporate income tax act for tax years beginning after December 31, 2011.

Expands the definition of "taxpayer" to include persons or unitary business groups that acquire certificated credits through reorganization or merger under IRC sections 708(b)(2), 368(a)(1), and 304(c).

Allows members of unitary business groups with specific certificated credits (sections 431 and 434) to file separately and claim those credits rather than filing combined returns, subject to specified limitations.

Permits a taxpayer that acquires credits through merger to elect business tax filing for the first tax year after acquisition, and allows such taxpayers to claim additional eligible certificated credits while continuing to file business tax returns until credits are exhausted.

Establishes a $25,000,000 annual cap for voucher certificate redemptions under section 434(5) for battery cell development, limited to 3 years and contingent on creating 100 additional jobs (400 total).
