Colorado Property Tax Proposal
Lawmakers were in a special legislative session to consider a deal to enact further tax cuts in exchange for conservative groups pulling Initiatives 108 and 50 off the November ballot.
Colorado’s grand bargain on property taxes concluded when Gov. Jared Polis signed HB1001 on September 4, 2024, and the two initiatives were withdrawn. Polis had previously said he would not sign the bill into law until the two ballot measures were formally pulled from the ballot. The Colorado Secretary of State’s Office confirmed that both had been withdrawn.
For tax year 2025, here's how the deal compares to the ballot measures and Senate Bill 233, which was signed into law earlier this year.
