Colorado: Wage Withholding Tax
If a business has employees in Colorado it must collect and remit wage withholding taxes from employees. Colorado's individual (personal) income tax rate is a flat 4.63% (tax rate may have been changed).
Colorado does not have an equivalent state form to the federal W-4. This is because the state income tax is based on the taxpayer's federal taxable income. An employer should use the information from the federal W-4 Form to calculate the state wage withholding amounts.
