A coalition of liberal groups hope to put a tax reform measure on the November 2026 ballot that could result in significant additional funding for K-12 schools and higher education.
The Protect Colorado’s Future coalition wants to amend a portion of the state’s constitution that mandates a flat income tax rate, currently set at 4.4%.
The draft measure, which the group unveiled Wednesday, would ask voters to approve a new graduated income tax. Taxes would remain at the same rate for earners making under $500,000 a year and progressively increase for earners who make above that threshold, up to 9.2% for earners who make $10 million or more. The group projects that lower earners would save several hundred dollars a year.
