Transportation

AB 219 creates a 50% tax credit for eligible rail infrastructure spending in Wisconsin. It directly affects Class II/III railroads operating in the state and owners/lessees of rail sidings or industrial spurs, covering both new track construction (like spurs and sidings) and track maintenance (such as rail, ties, and safety systems). The credit applies to expenditures made after December 2024, with annual limits of $5,000 per mile of track owned and $2 million per project. Unused credits can be carried forward for up to five years, and credits may be transferred to other businesses subject to Wisconsin taxes.
