Iowa voters are scheduled to decide whether income-tax increases should require a two-thirds legislative vote
Iowa voters are scheduled to decide in the 2026 election whether future state individual or corporate income-tax increases should require approval from two-thirds of both chambers of the Iowa Legislature.
The proposed constitutional amendment would also apply if lawmakers sought to create a new individual or corporate income tax. The measure is listed as an Iowa ballot proposal for the 2026 election cycle, with the general election scheduled for Nov. 3, 2026.
The available source materials do not provide final certified ballot language or an election result. They also do not establish whether the amendment has already been formally certified for the November ballot. The proposal should therefore be understood as a listed and scheduled election question, not as an adopted constitutional change.
What the amendment would change
If approved by voters, the amendment would change the legislative threshold for certain future tax decisions. A bill to increase an individual or corporate income-tax rate would need support from two-thirds of the members in both legislative chambers, rather than passing under the ordinary threshold that otherwise applies to legislation.
The same two-thirds requirement would cover the creation of a new individual or corporate income tax. The proposal concerns the rules lawmakers would follow when considering those changes; it does not directly change Iowa’s current tax rates.
That distinction is central. The measure would not impose an immediate tax increase, provide an immediate tax cut or determine the outcome of any specific future tax proposal. Instead, it would place a higher constitutional voting requirement on the Iowa Legislature for the specified income-tax actions.
Why the vote matters
The amendment would give Iowa voters a direct decision over the rules governing future state income-tax legislation. If approved, securing the required votes for an income-tax increase would become more difficult than under a lower legislative threshold.
That could matter during a state budget shortfall or a significant policy shift, when lawmakers might consider changes to individual or corporate income taxes as part of a broader fiscal response. The proposal could make those changes harder to enact because approval would require a two-thirds vote in each chamber.
The measure would affect legislative taxing authority rather than immediately changing what Iowa residents or businesses owe. Its practical effect would depend on future budget conditions, policy choices and whether lawmakers later seek to increase an income-tax rate or create a new income tax.
Election-year timing
Iowa’s 2026 legislative session ended May 4, 2026, according to the Iowa Department of Transportation’s official session-end notice. That means the development is now framed as an election-year constitutional question rather than as pending regular-session legislation.
The next known public step is the scheduled 2026 general election, listed for Nov. 3. The approved materials do not include a final certified version of the ballot language, campaign positions, an official fiscal estimate or a vote result.
Until voters decide the question and the state provides an official result, the amendment remains a proposal. A ballot listing alone does not establish that it will pass, and it does not show how Iowa voters will vote.
What Iowa residents should watch
The key question for voters will be whether to place a two-thirds constitutional voting requirement on future increases to individual or corporate income taxes and on the creation of a new income tax.
The measure is not a vote on a particular tax rate. It is a vote on the decision-making rule that would apply to later tax legislation. Residents, businesses and lawmakers will therefore be deciding whether future income-tax changes should face that higher legislative hurdle.
