Former Colorado Treasurer Links Graduated Income Taxes to Economic Growth
Denver Westword reports on the assertion by Colorado's former State Treasurer that states with a graduated income tax, similar to Amendment 87, exhibit strong economic growth.

Denver, CO, October 24, 2026 —
Denver Westword has reported an assertion by Colorado’s former State Treasurer that states with a graduated income tax, similar to Amendment 87, exhibit strong economic growth.
The claim links a state tax structure with economic performance, but the information provided does not identify which states the former treasurer cited or what measures were used to characterize their growth. It also does not provide a timeframe for the comparison or details about the evidence behind the assertion.
The summary does not name the former treasurer or explain how Amendment 87 relates to the tax structures discussed. It provides no information about the measure’s provisions, status or outcome. Those details cannot be established from the account summarized here.
Without the underlying comparisons or methodology, the statement should be understood as an assertion attributed to the former official, rather than a quantified finding presented in the available information. No figures or specific state examples are included.
The information provided also does not include responses from other officials, economists or affected states. Further details about the states, measures of economic growth and time period would be needed to assess the basis and scope of the reported claim.
