Introduction

In the last few days of session, SB24-233, a measure to address Colorado’s property taxes, was introduced. In the last few hours of session, the key question is: Will Coloradans pay more or less in property taxes?

Bottom Line: Under SB24-233, Coloradans will still see an increase in property taxes from what is being paid today. Next year, Colorado homeowners will pay the same elevated amounts from the spike in 2023. In 2025, the same year as the next reassessment period, property tax rates will increase, setting Coloradans up for another increase in their property tax bills. Crucially, any assessment of this bill should refer to what Coloradans currently pay in property taxes, not what they would pay if the actions from prior sessions were to sunset. SB24-233 comes at a time when the average Colorado household is spending $1,230 more per month due to inflation compared to what was spent in 2020.

As shown in tables below:

• There is no relief for taxpayers. Coloradans will not have property tax relief from recent spikes. As reported by CSI, residential property assessment values increased over 27% in 2023. Under SB24-233, Coloradans are locked into these recent elevated property tax payments, resulting in no tax relief for this year or next.
• Property taxes will continue to increase. Tax rates increase from what Coloradans are paying today under SB24-233. Even if the value of a home does not increase in 2025, property tax bills will still increase given the growth in underlying rates. For a household with a home valued at $400,000 in 2022, that just saw a spike in their tax bill this year, their effective property tax rate is set to increase from 5.14% under current rates, to 5.71% by 2026. Therefore, even if the value of their home does not change in 2025, they will see an 11%, or $318 increase in their bill. A $700,000 home would face a $403, or 8% increase through 2026. This is driven by an increase in the assessment rate from 6.7% today, to a combination of a 7.15% assessment rate for school districts and a 6.95% assessment rate for all other property tax districts.
• This is not a long-term fix. True property tax reform should provide more predictability to homeowners. The proposed 5.5% cap has true limitations. If the state sees another spike in home values, then Colorado is right back at the same place it was several years ago. The re-imposition of the 5.5% district revenue limit includes several carve outs including school districts (which represent over 50% of the tax base) home rule governments, and multiple other revenue sources including oil and gas operations and new construction.
