Should Colorado Have a Graduated Income Tax? Group Starts Process for Ballot Question

The proposal aims to raise $2.3 billion annually by increasing taxes on incomes over $500,000 and lowering rates for most taxpayers, addressing budget shortfalls and funding key services.

  • On Wednesday, the Protect Colorado's Future coalition will file measures to enact a graduated income tax on the 2026 ballot, aiming to raise $2.3 billion annually while lowering taxes for most and increasing rates above $500,000.
  • Supporters say TABOR's limits and a structural deficit prompted the proposal to replace lost Medicaid funding from H.R. 1, estimated at about $900 million in 2025-26 to $1.5 billion in 2026-27.
  • Under the proposal, rates would change so that individuals and businesses face 4.2% on the first $100,000, 4.4% on $100,001–$500,000, then 7.5% for $500,001–$750,000, 8.5% for $750,001–$1 million, and 9.5% over $1 million, targeting people earning at least $506,000.
  • The main obstacle is collecting 125,000 valid signatures, including 2% from each of Colorado's 35 state Senate districts, which can cost millions, and if approved by the title board in coming months, backers must gather signatures to secure a place on the 2026 ballot.
  • The political response is likely to be fierce since Colorado is one of just 14 states with a flat income tax, voters rejected Amendment 73 by nearly 54%, and Gov. Jared Polis plus conservative activists oppose the proposal.
