All figures and charts show 2024 tax law in Colorado, presented at 2023 income levels. Senior taxpayers are excluded for reasons detailed in the methodology. Our analysis includes nearly all (99.2 percent) state and local tax revenue collected in Colorado. These figures depict Colorado’s EITC at its 2024 level of 38 percent of federal. The credit will decline to 20 percent over the next two years. As seen in Appendix E, this will increase the bottom fifth’s overall tax rate by 1.0 percentage point and cause the state to move 3 spots in the ITEP Inequality Index rankings, from 39th to 36th most regressive.

ITEP Tax Inequality Index
Colorado has a hybrid system that is progressive through the bottom part of the income distribution and regressive through the top part. On balance, the overall system tilts regressive because high-income families pay the lowest overall tax rates. According to ITEP’s Tax Inequality Index, Colorado has the 39th most regressive state and local tax system in the country. Income disparities between high-income taxpayers and other families are larger in Colorado after state and local taxes are collected than before. (See Appendix B for state-by-state rankings and the report methodology for additional detail.)
