Complete statewide November roster identified from the official election guide or certified measure directory. Local measures are excluded.
- Amendment 81 — Immigration notifications after criminal charges
Would require reasonable efforts to determine lawful presence after a violent-crime charge, or any charge against someone with a prior felony. If lawful presence cannot be confirmed, covered officials must notify federal homeland-security authorities within 72 hours. The trigger is a charge, not a conviction.
- Amendment 82 — Constitutional right to natural gas
Would protect consumers’ right to buy natural gas for cooking or heating and distributors’ and utilities’ right to sell it for homes and businesses. The effect on existing regulations would depend on interpretation.
- Amendment 83 — Constitutional right to hunt and fish
Would create a constitutional right to hunt and fish by traditional methods and make these preferred wildlife-management tools. It excludes nongame and endangered species and federally prohibited hunting, preserves private-property rules, and allows regulation for science-based conservation, public safety and future opportunities.
- Amendment 84 — Identification numbers on mail ballots
Would require a signature plus the last four digits of a Social Security or qualifying Colorado ID number for federal and statewide mail ballots. Missing or mismatched information must be corrected within eight days after Election Day, with alternative ID options. In-person ID rules would not change.
- Amendment 85 — Plain-language ballot titles
Would require state and local ballot titles to be written at no more than an eighth-grade reading level. Laws requiring wording that interferes with plain language could not apply to citizen initiatives. The measure does not designate who decides compliance.
- Amendment 86 — Off-cycle congressional redistricting
Would require the independent congressional commission and state Supreme Court to approve off-cycle map changes after at least three public hearings. Such changes could not intentionally favor a party or unnecessarily divide communities of interest.
- Amendment 87 — Graduated income tax
Would replace the flat rate with six marginal brackets from 3.7% to 8.4%, starting in 2027. Additional revenue would supplement education, health and early-childhood programs and be exempt from TABOR. Brackets would not be inflation-indexed; principal-residence sale income retains 4.4% treatment.
- Proposition NN — Retain revenue for education and other purposes
Would permit retention up to a new limit linked to public-school spending. After existing property-tax reimbursements, money would support K–12 education and children’s programs for ten years; later it could also support other legislative priorities. Spending reports and audits are required.
- Proposition 132 — Fentanyl offense penalties
Would make possession of any amount of covered fentanyl substances a felony and require 8–32 years for distribution. It limits mitigating-factor and Good Samaritan reductions for distribution. Possession below one gram could still be reduced after successful required treatment.
- Proposition 133 — Penalties for trafficking a minor
Would require life without parole for child sex trafficking and add buying sexual activity with a minor to the covered acts. Existing protections for trafficking victims remain.
- Proposition 134 — Sex-based school and college sports
Would designate school-based teams male, female or mixed and assign participation by the measure’s definition of biological sex. Females could join male teams if no female equivalent exists. Schools would set verification policies; the proposal also bars penalties for designating female-only teams.
- Proposition 135 — Restrictions on certain surgeries for minors
Would prohibit surgery altering a minor’s sex characteristics when performed in response to the minor’s perception of sex or gender, and prohibit public or insurance payment. Exceptions include circumcision and specified sex-development or acquired physical conditions. Nonsurgical treatments are outside this ban.
- Proposition 136 — Income-tax rate limit
Would set 4.4% as the statutory maximum from 2027. It does not reduce the current rate or change the process by which voters could approve future increases.
- Proposition 137 — Sporting-goods sales tax for conservation
Would direct that existing revenue to conservation, wildfire mitigation, watershed restoration and outdoor programs without raising the tax rate. The retained amount would be exempt from TABOR, with adjustments to protect specified family tax credits.
