Two-Thirds Legislative Vote Requirement for Income Tax Increase Bills Amendment

Iowa · November 3, 2026

What this measure does

Require a two-thirds vote of both legislative chambers to pass a bill that would increase the individual or corporate income tax rate

A yes vote means Income tax increases would require a two-thirds vote in both the state Senate and House instead of a simple majority.
A no vote means Income tax increases would continue to require only a simple majority vote in the legislature, as they do now.
Simple explanation
Right now, lawmakers can raise income taxes with just a regular majority vote—like getting half your group to agree on something. This measure would make it much harder by requiring two-thirds of lawmakers to agree instead, kind of like needing two-thirds of your group to decide something big. It's basically making it easier to block tax increases than to pass them.
