SB25-003 makes it a crime to buy or sell most semiautomatic rifles, shotguns, and many handguns unless the buyer first takes a state safety class and gets an eligibility card from the county sheriff. It took effect August 1, 2026.

HB25-1133 bans stores from selling ammunition to anyone under 21, requires a photo ID for every in-person sale and every delivery, and covers out-of-state sellers who ship into Colorado. It took effect July 1, 2026.

SB25-276 bars every county, city, school, hospital, college, child care center, and library in Colorado from helping federal immigration agents, with fines up to $50,000. HB26-1276 aims the same fines at the private company that runs Colorado's immigration detention center. A federal judge has already blocked part of it.

SB25-183 adds abortion to Colorado's Medicaid program and its Child Health Plan Plus, pays for it with state tax dollars only, and removes the old state laws that barred public funding. It took effect January 1, 2026.

SB25-001 lets anyone sue a Colorado county, city, or town over any election practice that produces a "non-trivial difference" between racial groups, with no proof that anyone meant to discriminate. The first lawsuit arrived in June 2026, against Colorado Springs' April elections.

In six days in August 2025, Colorado passed four tax increases and a sale of future tax credits worth hundreds of millions of dollars. Lawmakers declared that none of them needed voter approval, and they blocked voters from putting any of them on the ballot. The only bill voters could still challenge was the one that raised no money.

HB25-1296 makes Colorado workers pay state tax on overtime pay that is tax-free on their federal return. Colorado signed it on May 16, 2025, seven weeks before the federal overtime tax break became law. It took effect January 1, 2026.

HB25-1204 turns the federal Indian Child Welfare Act into permanent Colorado law, so it survives even if the federal law is weakened or struck down. It passed almost unanimously, with Republican cosponsors. It deserves careful watching.

HB26-1309 changes how Colorado family courts weigh abuse in custody cases. It adds a broad definition of "coercive control," counts conduct that is not a crime, and presumes against shared decision-making once a judge finds abuse "more likely than not." The goal is serious. The details need work.

HB26-1335 requires every public and private college in Colorado that runs a student health center to give all enrolled students access to abortion medication, starting August 1, 2027. Religious colleges are exempt. Non-religious private colleges are not.
