* When paying by any electronic method through Revenue Online, do not submit a paper withholding tax return. A paper return AND an electronic payment for the same period results in a duplicate filing. When duplicate returns post to the taxpayer's account, the taxpayer will receive balance due notices because there is no payment with those duplicate returns. If you are filing and paying through Revenue Online, the filing and payment are made in a single transaction.
 
Filing on Paper
To ensure your payment is posted to your tax account, you must include the eight-digit Colorado Account Number (CAN) assigned to your account by the Department. Omitting this CAN could cause the account to be in a balance due situation and you will receive a Balance Due letter from the Department. Note: The Federal Employer Identification Number (FEIN) is not the same as the CAN and will not post the payment to your account.
 
Still Owe Tax After Filing
If you have a withholding tax bill, you should use the payment voucher document that comes with the “Statement of Account.” The payment and voucher should be mailed to the address on the “Statement of Account.” Currently, the only method of paying tax bills is by check or money order with the voucher.
