An Act to create 66.1105 (17) (c) of the statutes; Relating to: tax incremental financing districts containing qualified data centers. (FE)

Summary

SB241 creates a new exception in Wisconsin’s tax incremental financing (TIF) law for districts that contain a certified qualified data center. Under current law, a city or village generally cannot create or amend a TIF district if the district’s equalized value, together with the increment of existing TIDs, would exceed 12% of the municipality’s total equalized taxable property value. This bill would allow that 12% limit to be disregarded for a TIF district if the district contains a WEDC-certified data center and all project costs in the district are related to that data center. The bill also restricts how such a district may be used after creation. If a data center district was exempted from the 12% findings requirement, its project plan could not later be amended to add costs unrelated to the data center. In addition, when a local legislative body calculates the 12% cap for other TIF districts, it would have to exclude the value increment of any exempted data center district. The measure is aimed at facilitating development or expansion of large data center projects by making them easier to finance through TIF.

Impact

SB241 would amend Wisconsin Statutes section 66.1105 by creating a special rule for tax incremental districts containing qualified data centers certified under section 238.40 (2). The practical effect is to loosen the normal TIF size cap for certain data-center-only districts, potentially allowing municipalities to use TIF financing for large data center projects even when the standard 12% threshold would otherwise block creation or amendment of the district. It would also limit future changes to those districts and alter how municipalities calculate the cap for other TIDs by excluding the exempted district’s increment.

Sentiment

The available record shows no committee transcript or recorded votes, so there is no documented floor or committee debate to gauge detailed sentiment. The bill’s introduction with multiple Senate and Assembly cosponsors suggests at least some bipartisan or broad legislative interest in supporting data center development and related economic investment. However, the bill ultimately failed to pass pursuant to Senate Joint Resolution 1, indicating it did not secure final legislative approval.

Contention

The main policy issue is whether data centers should receive a special exemption from the TIF 12% cap that applies to other municipal development projects. Supporters likely view the bill as a targeted economic development tool to attract or expand high-value data center investment, while potential opponents may be concerned about carving out exceptions to TIF limits, reducing local fiscal discipline, and giving preferential treatment to one industry. The bill also raises a narrower concern about ensuring that exempted districts remain dedicated solely to data center-related costs, which is why the text bars later amendments for unrelated project costs.
