Wisconsin Data Center Tax Exemptions Face Political Pushback

Live Poll

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. Candidates now advocate for the repeal of these tax breaks due to rising public opposition and projections of substantial lost state revenue.

Why it matters

The exemption has become a central campaign issue because of its massive impact on the state budget and the potential for nearly $2 billion in combined annual revenue losses. Lawmakers and voters are scrutinizing whether the promised infrastructure growth justifies the long-term fiscal cost.

The Legislative Fiscal Bureau projects a $1.5 billion loss in sales tax revenue on construction costs and an additional $369 million annual loss from electricity usage tax exemptions. By 2028, technology companies could spend nearly $40 billion on building data centers in Wisconsin.

The players

Tony Evers

He serves as the Governor of Wisconsin and signed the state budget that included the controversial data center tax exemption.

Wisconsin Legislature

This is the state's lawmaking body that passed the 2023-25 budget containing the data center tax handouts.

Joint Finance Committee

This legislative committee oversees the state's budget process and approved the tax exemption measure in a 12-6 vote.

Legislative Fiscal Bureau

This nonpartisan agency provides fiscal and policy analysis to the Wisconsin Legislature and projected the multi-billion dollar revenue losses.

Marquette University Law School

This institution conducts regular public opinion polling that showed 74% of respondents believe data center costs outweigh economic benefits.

The details

The Joint Finance Committee approved Motion 126 in a 12-6 vote to implement the tax exemptions following intensive lobbying efforts from 15 organizations. These groups deployed 59 lobbyists to support the measure, which Governor Tony Evers eventually signed into law.

June 22, 2023: Joint Finance Committee introduced Motion 126.
2023: The Wisconsin Legislature passed the state budget.
March 2026: Legislative Fiscal Bureau released projection memo.
Oct. 21, 2026: Governor candidates debated the tax exemption.
Nov. 3, 2026: Election for governor and legislature.

The Tech Race

The push to attract data centers reflects a competitive strategy to secure massive infrastructure investments, similar to how other states compete for semiconductor or manufacturing hubs. Wisconsin's current debate over the 2023-25 state budget exemptions highlights the tension between incentivizing tech growth and protecting the state's long-term tax base.

The tax exemption may impact the state's ability to fund public services due to the projected $1.9 billion annual cost to the treasury. Residents should monitor how these potential revenue losses affect future state budget allocations for education and local infrastructure.

The takeaway

The data center debate underscores the importance of evaluating long-term fiscal trade-offs against immediate economic development goals. Voters and residents should pay close attention to how legislative candidates plan to balance these significant revenue impacts with future public spending needs.
