House Bill 5790 amends Michigan’s General Sales Tax Act to expand and extend sales tax exemptions for data center equipment. The bill preserves the existing exemption for qualified data centers and colocated businesses, while adding a new exemption framework for “enterprise data centers” that receive a certificate from the Michigan Strategic Fund. Under the new framework, eligible purchases of data center equipment used in constructing, operating, or fitting out a certified enterprise data center would be exempt from sales tax, subject to detailed eligibility, reporting, and compliance requirements.
To qualify, an enterprise data center must be located in Michigan, involve at least $250 million in aggregate capital investment, create and maintain at least 30 qualified new jobs paying at least 150% of the regional median wage, and meet a series of operational and environmental conditions. Those conditions include using municipal water with available capacity, obtaining certification under one or more green building standards, procuring clean energy equal to 90% of forecasted electricity use, avoiding certain electric rate structures, and taking direct steps to reduce environmental impacts such as improving energy efficiency and conserving water. The bill also limits new certificate issuance after December 31, 2029, and extends the exemption period longer for facilities on brownfield or former power plant sites.
The bill would affect the tax treatment of data center construction and operations by creating a targeted incentive for large-scale data center investment in Michigan. It also gives the Michigan Strategic Fund significant administrative authority to review applications, issue certificates, require annual reporting, audit compliance, revoke certificates if a facility no longer qualifies, and recapture tax benefits in some cases. The bill defines key terms such as qualified data center, colocated business, data center equipment, enterprise data center, qualified entity, and property tax benefits, and it coordinates with existing brownfield and utility-related laws.
Because no committee transcripts or recorded votes were provided, there is no documented public debate or voting pattern to assess. Based on the bill text alone, the measure appears designed to support economic development and data center expansion while adding environmental and labor-related guardrails. The overall tone of the legislation is incentive-oriented but conditional, suggesting support for the industry if it meets job, investment, and sustainability benchmarks.
Notable points of potential contention include the size of the tax exemption, the requirement that facilities avoid certain property tax benefits, the prohibition on some electric rate structures, and the environmental and clean-energy mandates. Local governments may also be affected because they must approve certain property tax benefits by resolution for the exemption to remain available. The recapture provisions and the Michigan Strategic Fund’s discretion over certification and revocation could also be areas of concern for applicants and policymakers.
HB 5790 would amend section 4ee of the General Sales Tax Act to broaden and restructure Michigan’s sales tax exemption for data center equipment. It would preserve the existing exemption for qualified data centers and colocated businesses, while creating a new certificate-based exemption for enterprise data centers that meet statutory investment, employment, environmental, and operational criteria. The bill would also authorize the Michigan Strategic Fund to administer applications, require annual reporting, monitor compliance, revoke certificates, and recover exempted taxes in certain cases. It would not only affect data center operators and contractors, but also local governments, utilities, and the Department of Treasury through the new certification and oversight process.
With no committee testimony or vote record available, the bill’s sentiment can only be inferred from its structure. The legislation appears generally favorable toward data center development and economic growth, offering a substantial tax incentive to attract large projects to Michigan. At the same time, it reflects caution and conditional support by tying the exemption to job creation, capital investment, green building certification, clean energy procurement, water use standards, and restrictions on certain tax and utility benefits. Overall, the bill reads as pro-development but heavily regulated.
The main points of contention are likely to center on whether the sales tax exemption is too generous relative to the public benefits promised, and whether the bill’s conditions are sufficient to protect taxpayers, utilities, and local communities. Environmental advocates may focus on the bill’s energy and water demands, while data center developers may view the clean-energy, water, and rate restrictions as burdensome or difficult to satisfy. Local governments may object to limits on property tax benefits and the need for local approval of certain incentives, and utilities may be affected by the requirement to structure service in ways that avoid shifting costs to residential customers. The Michigan Strategic Fund’s broad role in certification, monitoring, and revocation may also be a point of concern for both supporters and opponents.
