Submitting files

If Colorado tax is withheld, payers are required to have a Colorado 1099 and/or W-2G withholding account and remit the tax.

If a payer files 1099 or W-2G withholding statements electronically through Revenue Online, the payer does not need to submit a DR 1106 or 1101 unless an amount appears on 3A (additional balance due) or 3B (a refund) of the return.

Register the submitter at least five days prior to submitting the file. Access Revenue Online.

Anyone who will submit W-2s, 1099s, or W-2Gs– whether a tax professional, tax service provider and/or a person who does the payroll at the business – must register.

A) Go to Revenue Online at least five days before you plan to submit a file or type each W-2, 1099, or W-2G entry.

B) Click on the hyperlink to “Submit Year-End Withholding” under the heading “Additional Services.”

C) Click on the link Request Withholding Submitter Access.

D) Complete the requested fields.

A Confirmation will appear to confirm that the department has received the registration request. In most cases, the registration process is completed overnight; however, it may take up to five business days to complete.

When you have completed the registration process, you do not need to do it again.

CORRECTING 1099'S/W2G'S

If a 1099 or W-2G is issued with any errors, the payee must send a corrected 1099/W2G to correct the error to the

department on or before the due date of the original W-2 (January 31). If too little was withheld, the Department

will send a bill to the payer for the difference. If too much was withheld, the payer must request a claim for

refund for the difference. Submit the corrected 1099 or W-2G forms with a cover letter to:

Colorado Department of Revenue, Discovery Section Room 634, P.O. Box 17087, Denver, CO 80217-0087.
