What it would have done
Summary by the , the Legislature's nonpartisan drafting office. It's their wording, not ours.
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 referred to the Joint Survey Committee on Tax Exemptions for a report to be printed as an appendix to the bill.
