Colorado Payroll & Paycheck Tax Calculator

To legally hire employees in Colorado, you’ll need to register with the Colorado Department of Revenue for income tax withholding and the Colorado Department of Labor and Employment (CDLE) for unemployment insurance. Colorado’s online services make registration as smooth as fresh powder on the slopes. Don’t forget to register for FAMLI (Family and Medical Leave Insurance) as well.

New employers pay 1.7% unemployment tax on the first $23,800 of each employee’s wages—one of the higher wage bases in the nation.

The Centennial State’s paperwork includes some unique elements:
• Federal W-4 for withholding (Colorado uses federal W-4 data)
• Federal forms from the IRS: • Form 941 (Quarterly federal tax return) • Form 940 (Federal Unemployment Tax, FUTA) • W-2 and 1099 (Year-end wage reporting)
• New Hire Reports: Submit within 20 days to Colorado State Directory
• Workers’ Compensation: Required for all employers with employees
• Form DR 1094: Quarterly withholding return
• FAMLI registration and quarterly reporting
• Local tax registrations where applicable
Several Colorado cities and counties impose their own occupational or head taxes, adding complexity to payroll calculations.

Colorado’s minimum wage is $14.42 per hour as of 2025, with annual adjustments based on cost of living. Tipped employees must receive at least $11.40 per hour in direct wages. Denver has its own higher minimum wage rates that employers must track separately.

Colorado’s overtime rules exceed federal requirements: 1.5x regular pay after 40 hours per week OR 12 hours in a single day. The state also mandates overtime for consecutive hours worked beyond 12, regardless of the workweek total.

Colorado doesn’t mandate specific pay frequencies, but employers must establish regular paydays and maintain them consistently. Most employers choose weekly, bi-weekly, or semi-monthly schedules. Monthly payment is allowed for exempt employees.

For final paychecks, Colorado requires immediate payment upon termination if you fire an employee. If an employee quits, final wages are due on the next regular payday. Special rules apply for commission and piece-rate workers.

Colorado mandates paid sick leave (1 hour per 30 hours worked, up to 48 hours annually) and requires participation in FAMLI, providing up to 12 weeks of paid family and medical leave.
