Removed from ballot

Withdrawn ballot initiatives

The following initiatives qualified for the ballot but sponsors withdrew their proposals.

On September 4, 2024, Advance Colorado withdrew its two property tax ballot initiatives from the November 2024 ballot: Initiative 50, the property tax revenue cap initiative, and Initiative 108, the property tax valuation reduction initiative.

Colorado Gov. Jared Polis (D) signed the compromise bill, House Bill 24B-1001, into law on the same day. Polis had called the state legislature into a special session to address property taxes. HB 2001 was designed to reduce property taxes and cap local government and school district tax revenue growth.

Polis said, "The cost of inaction is too high. We refuse to gamble with our schools, our economy, our future. Proposed ballot measures threaten to gut funding for K-12 and higher education, and Coloradans are counting on us to find a path forward that saves people money on property taxes while preserving these critical institutions."

Advance Colorado President Michael Fields said, “This property tax cut and cap agreement provides the permanent tax relief that Coloradans have been demanding and will prevent future spikes in property tax bills going forward."

Type	Title	Subject	Description	Reason	Status
CICA	Property Tax Revenue Cap Initiative	Taxes and Property	Limit property tax revenue from increasing beyond 4% growth from the total statewide property tax revenue collected in the previous year; require statewide voter approval to retain property tax revenue above the cap	Legislative compromise enacted
CISS	Property Tax Valuation Reduction Initiative	Taxes and Property	Reduce property tax valuation assessment rates	Legislative compromise enacted

Legislative referrals

The Colorado General Assembly may also propose amendments to the people as legislatively referred constitutional amendments. A two-thirds vote of each chamber of the legislature is required to refer an amendment to the ballot. Constitutional amendments require voter approval of 55% to be adopted.

Initiatives

In Colorado, citizens have the powers of initiative, both statute and constitutional, and veto referendum. To get an initiated state statute or initiated constitutional amendment on the ballot in 2024, proponents need to collect 124,238 valid signatures. Petitioners have six months to circulate signature petitions. The deadline for submitting signatures was August 7, 2023.

Colorado is one of 23 states that allow citizens to refer an enacted bill to the ballot as a veto referendum. As with initiatives, a veto referendum requires 124,238 valid signatures. The signature deadline was August 5, 2024, by 5 p.m. local time. A referendum petition must be filed within 90 days following the Colorado General Assembly's final adjournment of the session in which the bill was passed.

The following citizen initiatives did not submit the required number of valid signatures before the deadline, or, in the case of legislative referrals, were not passed by both chambers of the Legislature, and therefore were not included on the ballot.
