Two-Thirds Vote for Income Taxes

Explain it like I'm 5

Lawmakers can now raise state income taxes with a little more than half the votes. This would require about two out of every three lawmakers in both chambers, like needing most of a class to agree before changing a rule.

Yes vote

The Iowa Constitution would require two-thirds of both the House and Senate to raise individual or corporate income tax rates or create certain new state income-based taxes.

No vote

The current rule remains, allowing a simple majority in both chambers to raise or create those state income taxes.

The question to ask yourself

Should broad agreement be required to raise state income taxes, or should a simple legislative majority retain more budget flexibility?

The case for

  • Tax increases would require broader agreement instead of a narrow majority.
  • It could protect recent income-tax cuts from quick reversal.
  • Supporters say it encourages lawmakers to control spending before raising taxes.

The case against

  • A minority could block needed revenue during a budget shortfall or emergency.
  • It could push lawmakers toward sales taxes, fees, or spending cuts instead.
  • Putting the rule in the Constitution would make future changes harder.

Money
The amendment itself has no direct cost and changes no current tax rate; future tax effects are not estimated.
Don't be misled
It does not freeze taxes or ban increases, because lawmakers could still raise covered taxes with two-thirds support and other taxes are outside the rule.
