Certain defined terms maintained, and data center exemptions modified.
HF4173 revises Minnesota’s sales and use tax exemption rules for data centers and adds a new category for “qualified large-scale data centers.” The bill keeps certain defined terms in place for other statutory purposes, but it changes the tax exemption framework by expanding and clarifying what qualifies as data-center-related equipment and by creating a separate definition for very large facilities. Under the bill, enterprise information technology equipment includes computers and supporting equipment such as servers, routers, cooling systems, power infrastructure, cabling, and related components needed to operate the facility.
The bill preserves the existing exemption for purchases of enterprise information technology equipment and computer software used in qualified data centers, qualified refurbished data centers, and qualified large-scale data centers. It also establishes a new large-scale data center threshold: a Minnesota facility of at least 25,000 square feet, connected by fiber, with at least $250 million in combined construction/refurbishment and technology/software investment by the facility and its tenants within a 60-month period beginning after June 30, 2025. The exemption for these facilities can apply for purchases made within 35 years of the first qualifying purchase, and only for facilities certified before July 1, 2042.
The bill also adds labor and sustainability conditions specifically for qualified large-scale data centers. Covered construction or refurbishment work must be paid prevailing wages, and the facility must obtain certification under one or more recognized green building or energy standards within three years after being placed in service. If the facility fails to meet the sustainability requirement, the exempted tax amount must be repaid, although the Department of Revenue may still assess tax, interest, or penalties if purchases do not otherwise qualify.
In terms of state law impact, HF4173 amends Minnesota Statutes sections 216B.02 and 297A.68 and affects how the Department of Employment and Economic Development and the Department of Revenue certify and administer data center tax exemptions. It expands the statutory definition of qualifying equipment, creates a new large-scale data center category, and imposes additional compliance, certification, and repayment requirements tied to sales tax refunds and exemptions. The bill is effective in stages, with different provisions beginning July 1, 2026, and the sales tax changes applying to sales and purchases made after June 30, 2026.
The overall sentiment reflected in the bill text is pro-investment and pro-development, with an emphasis on attracting or retaining major data center projects while tying tax benefits to wage and sustainability standards. Because there are no committee transcripts or recorded votes provided, there is no direct evidence of opposition or support from debate or roll call history. The main points of potential contention are the size of the tax exemption, the long duration of eligibility, and whether the prevailing wage and green-building requirements are sufficient safeguards for public benefit.
HF4173 would amend Minnesota’s data center sales tax exemption statute by expanding the definition of qualifying equipment, adding a new “qualified large-scale data center” category, and extending exemption eligibility to very large projects meeting a $250 million investment threshold. It also imposes certification, prevailing wage, and sustainability requirements on large-scale data centers, and it changes the administrative role of the Departments of Employment and Economic Development, Revenue, and Commerce in certifying and enforcing eligibility. The bill affects data center operators, tenants, contractors, and state tax administrators, and it would apply prospectively to sales and purchases after June 30, 2026.
The bill appears generally favorable toward data center development and tax incentives, while also reflecting an effort to address public concerns through labor and environmental conditions. In the absence of committee testimony or votes, the available text suggests a policy balance between economic development and accountability rather than a clearly partisan or controversial posture. The inclusion of prevailing wage and green certification requirements indicates an attempt to make the exemption more politically acceptable.
The most likely points of contention are the scope and cost of the sales tax exemption, the long 35-year exemption window, and the high investment threshold that could concentrate benefits among a small number of large projects. Supporters would likely emphasize job creation, capital investment, and Minnesota’s competitiveness for data center projects, while critics may question whether the public return justifies the tax expenditure. The prevailing wage and sustainability provisions may also be debated, with labor advocates likely supporting them and some project developers potentially viewing them as added compliance costs.
