Colorado's flat, TABOR-variable income tax is a real, current factor
Colorado taxes income at a flat 4.40% rate for 2026 -- not fully fixed, since a TABOR mechanism can temporarily lower it further in years the state certifies a qualifying revenue surplus. This is a meaningfully different structure than the no-income-tax states (TX, TN, FL) built earlier in this dataset.
