MI SB0184

Establishes a tax credit for Michigan taxpayers who purchase a qualified principal residence or retrofit their home for accessibility or visitability during tax years 2018-2022.

Credits equal 4.0% of purchase price for qualified residences or 50% of retrofitting costs, capped at $5,000 per residence with a limit of one credit per property.

Requires taxpayers to obtain certification from the Michigan State Housing Development Authority by January 10 of the year following the tax year in which the purchase or retrofit occurs.

Limits total annual credits to $1,000,000, with $500,000 allocated each for home purchases and retrofitting, allowing unused allocations to transfer between categories.

Allows unused credits exceeding tax liability to carry forward for up to 7 years; defines qualified residences as those with zero-step entrance, main floor bathroom, and 32-inch doorway clearance.
