Bill Overview
Analyzed Economic Effects
2 provisions identified: 1 benefits, 0 costs, 1 mixed.
Heating credit claimants must accept weatherization help
Michigan home heating credit claimants must accept weatherization help when they qualify and the help is available. The Treasury Department must refer eligible credit claimants to the appropriate state agency to check whether they qualify for weatherization. The law took effect immediately upon enactment.
National inflation measures guide heating credit limits
Michigan’s home heating credit now uses national prices instead of Detroit-area prices to adjust two limits. The heating-cost limit uses household-energy prices, while household-resource limits use prices for all items. Each compares the 12 months ending August 31 of the tax year with the same period one year earlier. Annual increases cannot exceed 10%, and adjusted limits round to the nearest dollar. The change took effect immediately upon enactment.
