Employers and third-party administrators (TPAs) will be prompted to pay Unemployment Insurance (UI) premiums once they have filed their quarterly wage report. Premium payments can be made electronically in MyUI Employer+, or by paper check mailed to the Division.
Electronic Payments
UI recommends paying premiums online in MyUI Employer+ for faster and more accurate processing. Employers and TPAs can make premium payments online using Automated Clearing House (ACH) Credit and ACH Debit.
Paper Check Payments
Employers and TPAs paying premiums by paper check must include a printed payment voucher to ensure accurate processing. Payment vouchers can be generated inside MyUI Employer+. The Division recommends including the employer account number (EAN) on the physical check to ensure accurate payment processing.
Paper checks and the related payment voucher should be mailed no later than five days prior to the due date to ensure timely receipt.
Mail the paper check and payment voucher in a sealed envelope to:
Colorado Department of Labor and Employment
P.O. Box 956
Denver, CO 80201-0956
Payments received by mail will be posted to the employer’s account and viewable inside MyUI Employer+ once received and processed. Visit the Make and Manage Payments page for more information and step-by-step instructions.
Voluntary Premium Payments
Employers who have an experience (computed) rate may choose to make voluntary premium payments (VPP). Making a voluntary payment can change an employer’s percent of excess, which may lower an employer’s Unemployment Insurance (UI) rate in a calendar year.
A voluntary payment is not a prepayment for premiums that an employer will owe. Once an employer makes a voluntary payment, it cannot be refunded.
Note
Employers may not make voluntary payments if they owe past-due payments.
Making a voluntary premium payment
Voluntary Premium Payments can be made online in MyUI Employer+, or submitted by mail. To submit a voluntary payment by mail, employers must include:
- A paper check made out to the Colorado State Treasurer.
- A printed payment voucher.
- A copy of their UI Rate Notice form.
- A letter informing the Division that the employer is making a voluntary payment to lower their rate.
Employers should mail their check, payment voucher, Rate Notice, and letter of intent to:
Colorado Department of Labor and Employment
