DR 0004 - Colorado Employee Withholding Certificate

#FFFFFF

This Certificate is Optional for Employees. If you do not complete this certificate, then your employer will calculate your Colorado withholding based on your IRS Form W-4. That calculation is designed to withhold the required Colorado income tax due on your wages throughout the year, and it will generally result in a refund when you file your Colorado income tax return. 

If You Complete This Certificate: 

1. Give it to your employer; then they must calculate your Colorado withholding based on the amounts you entered.

2. If you (and your spouse, if filing jointly) have multiple jobs, complete a separate certificate for each one.
