What’s in it
AI summary This resolution would change the Iowa Constitution to require two-thirds of lawmakers to agree before increasing certain income or corporate taxes or creating new ones. It also moves the state toward a single tax rate for individuals instead of having different rates for different income levels. If voters approve these changes, the state legislature must pass laws to make them work.1
Read the official explanation
This joint resolution proposes amendments to the Constitution of the State of Iowa by restricting certain state tax law changes and requiring a single rate for individual income taxes. RESTRICTIONS ON CERTAIN STATE TAX LAW CHANGES. The amendment requires a bill that increases the individual income tax rate or corporate income tax rate, or the rate of any other type of tax based upon income or legal and special reserves, to be adopted by at least two-thirds of the members elected to each house of the general assembly. In addition, the amendment requires a bill that establishes a new tax on any type of income or legal and special reserves imposed by the state to be adopted by at least two-thirds of the members elected to each house of the general assembly. A lawsuit challenging enactment of a bill subject to the two-thirds majority passage requirement must be filed no later than one year following the enactment of the bill. Finally, the amendment requires the general assembly to enact laws to implement the amendment. SINGLE INDIVIDUAL INCOME TAX RATE. 2006 taxation on such income is prohibited. The amendment prohibits more than one income tax rate above zero imposed by the state for state purposes on an individual at any one time. REFERRAL. The resolution, if adopted, would be published and then referred to the next general assembly (91st) for adoption, before being submitted to the electorate for ratification.
