Notable Colorado Tax Features
Colorado voters can approve a Taxpayer's Bill of Rights (TABOR) refund when state revenues exceed the cap. In some years, this results in a lower effective rate or a one-time refund. Denver does not levy a city income tax, but does collect a 0.5% Employee Occupational Privilege Tax (OPT) on wages.
