Do you support tax breaks for large technology companies building data centers in your state?

The Wisconsin Legislature approved a sales tax exemption for certified data centers within the 2023-25 state budget. This policy, enacted in 2023, is now under political scrutiny due to projected revenue losses and public opposition.

Why it matters

The exemption represents a high-stakes trade-off between aggressive infrastructure incentives and long-term fiscal stability. The projected revenue impact of billions of dollars has now become a central point of debate for state leadership.

The Legislative Fiscal Bureau projects a $1.5 billion loss in sales tax revenue from construction costs and a $369 million annual loss from electricity usage exemptions. These figures contrast with the estimated $40 billion in data center construction spending anticipated by 2028.

The players

Tony Evers

The current Governor of Wisconsin who signed the 2023-25 state budget.

Wisconsin Legislature

The state governing body that passed the data center tax exemption in a 12-6 committee vote.

Legislative Fiscal Bureau

The state office providing independent, nonpartisan fiscal and budgetary information to the legislature.

The details

The tax exemption was incorporated as Item 12 of a budget amendment following backroom negotiations involving 59 lobbyists. It functions by relieving certified data center operators of state sales taxes on equipment and energy, which are typically significant capital and operational expenditures in large-scale computing facilities. These facilities, designed to house high-density server racks and power distribution infrastructure, are now subject to public scrutiny regarding whether their tax-exempt status yields a net positive for the state economy.

June 22, 2023: The Joint Finance Committee introduced the tax exemption.
2023: The Wisconsin Legislature passed the state budget containing the measure.
March 2026: The Legislative Fiscal Bureau released a projection memo on revenue loss.
Oct. 21, 2026: Governor candidates debated the merits of the exemption.
Nov. 3, 2026: Voters head to the polls for the gubernatorial and legislative election.

The Tech Race

The exemption follows an industrial incentive model intended to compete for large-scale data center infrastructure projects. It places Wisconsin in direct competition with other states offering tax subsidies to attract hyperscale computing capacity.

The economic impact of this policy reaches taxpayers who now face a projected $1.869 billion total biennial revenue loss for the state. Residents should monitor the upcoming November 2026 election, as candidates have explicitly proposed repealing these exemptions.

The takeaway

The fiscal feasibility of this policy remains a primary concern as 74% of respondents in a Marquette University Law School poll express skepticism regarding the benefits. Watch the November 3, 2026, election results to determine the future of the exemption.
