Bill Summary
This bill adopts, for state income and franchise tax purposes, changes made to the federal Internal Revenue Code so that the state tax code, generally, conforms to the federal tax code. The bill also modifies rules promulgated by the Department of Revenue with regard to reporting non-wage payments, rents, and royalties, so that the rules also confirm with recent changes made to the federal Internal Revenue Code. Because this bill relates to an exemption from state or local taxes, it may be LRB-5030/1 JK:skw 2025 - 2026 Legislature SENATE BILL 859 referred to the Joint Survey Committee on Tax Exemptions for a report to be printed as an appendix to the bill. For further information see the state fiscal estimate, which will be printed as an appendix to this bill.
AI Summary
This bill aims to align state tax laws with recent changes in the federal Internal Revenue Code, or IRC, which is the body of federal law concerning taxation in the United States. Specifically, it updates the state's definition of the IRC to reflect amendments made up to December 31, 2025, for taxable years beginning after that date, while also specifying certain federal provisions that will not be adopted for state tax purposes. Additionally, the bill modifies administrative rules concerning the reporting of non-wage payments, such as rents and royalties, to align with federal reporting thresholds, which are now tied to the IRC's Section 6041(a) amount rather than a fixed $600. This ensures that businesses and individuals report payments to the state in a manner consistent with federal requirements, simplifying compliance and potentially preventing revenue loss.
