Colorado has a flat income tax rate of 4.4%, applied to federal taxable income with some modifications. The state also offers a TABOR refund mechanism that returns excess tax revenue to taxpayers.

All self-employed individuals in Colorado must make quarterly estimated tax payments to the IRS if they expect to owe $1,000 or more.
