Mark Born, Wisconsin State Representative for 37th District | Official Website
According to the Wisconsin State Legislature's official website, the bill was described as follows: "tax incremental financing districts containing qualified data centers. (FE)".
The following is our breakdown, based on the actual bill text, and may include interpretation to clarify its provisions.
In essence, this bill creates an exemption from the existing requirement that the equalized value of taxable property within a new or amended tax incremental district (TID), along with existing TIDs, not exceed 12% of a city or village's total equalized value. Specifically, the bill stipulates that this 12% limit does not apply to TIDs that encompass a qualified data center, provided that all project costs are related solely to the data center. The bill ensures that any data center district, if exempted from the 12% rule, cannot amend its project plan to include costs unrelated to the data center. This amendment is designed to support the development and operation of data centers, which are certified by the Wisconsin Economic Development Corporation, by allowing greater flexibility in tax incremental financing when certain conditions are met.
The bill was co-authored by Senator John Jagler (Republican-13th District), Representative Benjamin Franklin (Republican-88th District), Representative Chanz J. Green (Republican-74th District), Representative Brent Jacobson (Republican-87th District), Representative Daniel Knodl (Republican-24th District). It was co-sponsored by Senator Dan Feyen (Republican-20th District), along five other co-sponsors.
Mark Born has co-authored another two bills since the beginning of the 2025 session, with none of them being enacted.
Born graduated from Gustavus Adolphus College in 1998 with a BA.
Born, a Republican, was elected to the Wisconsin State Assembly in 2025 to represent the state's 37th Assembly district, replacing previous state representative William Penterman.
In Wisconsin, the legislative process starts when a senator, constituent, group, or agency proposes an idea for a bill. After drafting, the bill is introduced, numbered, and referred to a committee for review and public input. If approved, it moves through three readings and votes in both the Senate and Assembly. Once both chambers pass the same version, the bill goes to the governor, who can sign it, veto it, or let it become law without a signature. Only a small share of bills introduced each session ultimately become law. You can learn more about the Wisconsin legislative process here.
