ColoradoCare was a citizens' initiative to amend the Constitution of Colorado to provide a system of universal health care. It was on the ballot in Colorado on November 8, 2016 as Colorado State Health Care System Initiative, Amendment 69.
Like all ballot initiatives in Colorado, 100,000 signatures were required to put the proposal on the ballot. ColoradoCare would be financed by a payroll and income tax of 10% (premiums of 3.33% for employees and 6.67% for employers). It would begin operating in 2019 and is estimated to require revenue of $38 billion annually (from the Federal government and payroll taxes) and provide coverage for all residents, with no deductibles.
