From Iowa General Assemblies Pass Amendment 1, Requiring Supermajority for Tax Hikes

How could Amendment 1 affect Governor Kim Reynolds' fiscal authority in Iowa?

Possible What happens if… A possibility worth considering, not a forecast.

Amendment 1 may limit Kim Reynolds' ability to raise income taxes in Iowa. The passage of Amendment 1 requires a two-thirds majority vote of the Iowa Legislature to raise any existing income tax or create a new one. This constitutional hurdle restricts the state's primary mechanism for increasing income tax revenue. As Governor, Kim Reynolds manages the state's fiscal policy and budget, and this amendment limits the legislative options available to fund state operations or address budget shortfalls. While the amendment does not make tax increases impossible, it makes them significantly harder to achieve.

The facts so far

As reported. Each one links to where it comes from.

  • Amendment 1 would require a two-thirds majority vote of the Iowa Legislature to raise any existing income tax or create a new one.thegazette.com
  • Iowa currently has a flat-rate individual income tax of 3.8% and corporate rates between 5.5% and 7.1%.thegazette.com
  • Sixteen states currently require at minimum a three-fifths majority to increase at least one or more major taxes.thegazette.com

Why it matters

For Governor Kim Reynolds, the amendment represents a structural limitation on the state's fiscal toolkit. While she has previously attempted to increase the sales tax rate, the amendment adds another layer of difficulty to raising state revenue through income taxes, potentially constraining her ability to fund state priorities or respond to economic shifts.

This measure is part of a broader national trend where states are debating how to balance tax competitiveness with the need for stable government funding. The amendment is framed by proponents as a protection for taxpayers against politicians who might otherwise seek to raise taxes easily.

What we don't know yet

  • Will the amendment pass in the 2026 general election?
  • How will the state budget be adjusted if income tax increases become significantly more difficult?

What would change this answer

The Iowa Legislature shifts its political balance of power.A change in legislative control could alter the political feasibility of overcoming the two-thirds threshold, making the effect on the Governor more or less pronounced.
A major economic downturn occurs in Iowa.Increased fiscal pressure from a recession would make the revenue constraints imposed by Amendment 1 more critical for the Governor's operational planning.
