Iowa voters passed a constitutional amendment last week, with 56% in favor, that shields credit union members from future tax increases.
The Iowa Credit Union League spent several years working with state lawmakers to get here. Amending the constitution isn’t a one-and-done vote. The resolution had to clear two consecutive General Assemblies before it could reach the general election ballot. Lawmakers passed House Joint Resolution 2006 in 2024, then followed up with Senate Joint Resolution 11 in 2026, which put it in front of voters this year.
Here’s the language voters saw on the ballot:
“Passage of a bill that increases the individual income tax rate or the corporate income tax rate, or the rate of any other type of tax based upon income or legal and special reserves, shall require the affirmative votes of at least two-thirds of the members elected to each house of the general assembly.”
What changes in practice
Before, the legislature could raise the moneys and credits tax with a simple majority. Now it takes a two-thirds vote. The same higher bar applies to any increase in individual or corporate income tax rates under the resolution.
That gives the cooperative tax structure credit unions operate under strong constitutional protection. For member-owners, it means a much harder road for anyone hoping to raise taxes on their financial cooperatives down the line.
What the League is saying
Murray Williams, President and CEO of the Iowa Credit Union League, called the result “a significant win for credit union members in Iowa.” He said it “ensures that our movement’s tax status as a member-owned cooperative stays intact for years to come.”
He also tied it to household budgets. “With many Iowans struggling with the cost of living, credit unions will continue to advocate for their members to ensure they can keep more of their hard-earned money in their pockets,” Williams said.
What to do with this
If you’re a credit union member in Iowa, nothing changes in your account, but your institution’s tax status is now on firmer footing. Ask your credit union how it plans to keep members informed on legislative issues, and pay attention to what your state lawmakers do on tax policy. The amendment raises the bar for tax hikes, and staying engaged helps keep it there.
