NEWS BRIEF
The Denver Gazette reports that former Colorado Attorney General and U.S. Sen. Ken Salazar is opposing Amendment 87, a proposed constitutional amendment that would replace Colorado’s flat income tax with a graduated system. Under the proposal, businesses and households earning more than $500,000 annually would pay higher income taxes, while those below that threshold would receive a cut.
The report also says a Denver District Court judge allowed Amendment 87 to remain on the ballot after rejecting a challenge to petition-circulator procedures. The plaintiff’s lawyers said they plan an expedited appeal to the Colorado Supreme Court.
What to know
Amendment 87 would establish graduated income-tax rates in Colorado, with higher rates for businesses and households earning more than $500,000 a year. Its ballot status may remain subject to further court review if the planned appeal proceeds.
