This PPT Tool Kit is designed to help you exempt your manufacturing personal property from taxation. MMA is proud of its work to eliminate this tax exclusively for manufacturers through both legislative action and a successful $8 million statewide ballot campaign in 2014. We encourage you to take action and file annually with Form 5278 to get your exemption. It is not automatic — you must file the form every year to be exempt. The deadline this year is February 22, 2022. To learn more, visit the Michigan Manufacturers Association PPT Tool Kit information page.
