Should companies receive tax exemptions for equipment used on property they do not own?
The Michigan Tax Tribunal recently ruled that Plug Power Inc. cannot claim a personal property tax exemption for hydrogen equipment installed at local Stellantis manufacturing facilities. This decision applies to hardware currently supporting vehicle production at two Warren-based plants.
Why it matters
Tax status for industrial equipment can influence the long-term operational costs and viability of clean-energy infrastructure installed by third-party suppliers on manufacturing campuses. The ruling clarifies the strict requirements for property ownership when claiming specific local tax breaks.
The Michigan Tax Tribunal denied the exemption for equipment at two Stellantis car plants in Warren. The equipment consists of hydrogen fuel cells and dispensing hardware used for Jeep Wagoneer and Chrysler production.
The players
Plug Power Inc.
A provider of hydrogen fuel cell systems and infrastructure that supports clean energy solutions for heavy industrial and manufacturing applications.
Stellantis NV.
A major automotive manufacturer that produces vehicle brands including Jeep and Chrysler at its various production plants.
Michigan Tax Tribunal
An administrative body that resolves disputes and interprets tax laws regarding property and business taxation within the state of Michigan.
The details
The tribunal judge determined that the equipment failed to meet the state's exemption criteria because Plug Power Inc. does not own the real property where the fuel cell systems are located. To qualify for such personal property tax exemptions in Michigan, the party seeking the status must hold title to the underlying land or site. Because the hardware is integrated into existing Stellantis facilities rather than owned by the supplier, the exemption was denied.

The Home Front
This ruling highlights the complex intersection between industrial sustainability investments and property tax law. It reaffirms established standards in Michigan that link tax exemptions to the actual ownership of the land where equipment resides.
While this ruling concerns industrial tax law, homeowners and small business owners should verify property ownership requirements when installing high-value equipment that may impact local tax assessments. Consult with a licensed tax professional or property attorney to understand how your specific equipment and site configuration affect your local tax liabilities.
The takeaway
Tax exemptions for equipment are rarely blanket benefits and often hinge on the specific legal relationship between the asset owner and the property owner. Business owners should document their real property holdings carefully when planning infrastructure improvements that might trigger tax assessment changes.
