Colorado's corporate income tax rate is a flat 4.63 percent, assessed on Colorado net income, defined as the corporation's federal taxable income, with some modifications. Colorado allows businesses to either use a two-factor formula (revenue and property) or a three factor formula (revenue, property, and payroll), whichever is less in determining income tax.
