MI HB4472

Prohibits the Michigan Economic Growth Authority from modifying or amending existing written agreements with taxpayers for certificated credits under sections 430, 431, 431a, 431b, 431c, 432, 434, or 450 unless the modification reduces the net credit amount to the taxpayer.

Prevents modifications or amendments that decrease job creation or retention requirements, extend the credit term or timeframe, or add facilities whose jobs count toward requirements.

Requires the authority to notify the governor, auditor general, house and senate fiscal agencies, and legislature by email at least 30 days before modifying an agreement, including the taxpayer name, description of changes, and fiscal impact.

Establishes a 60-day deadline for taxpayers to submit certificated credit applications after meeting requirements under their written agreement, and a 210-day deadline to submit the credit with their annual tax return after receiving it.

Requires taxpayers who fail to meet agreement requirements to notify the authority within 60 days after their tax year ends; taxpayers who miss filing deadlines forfeit the right to claim that certificated credit.
