File Withholding 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. You cannot submit documents until the registration process is complete.

1. Go to Revenue Online at least 5 days before you plan to file a W-2, 1099, or W-2G entry.
2. In the "Withholding" menu panel, click "Submit Year End Withholding" 
3. Click on the link "Request Withholding Submitter Access"
4. Complete the requested fields.
5. Be sure to include an email address for your account.
6. Click "Submit"
7. A confirmation will appear that the Department has received the registration request. A confirmation will also be sent to you via email. In most cases, the registration process is completed overnight. However, it may take up to 5 business days to complete.

Once you have completed the registration process, you do not need to do it again. Each year when you submit your W-2s, 1099s, or W-2Gs in Revenue Online, you will start at the drop-down for "Submit Year End Withholding."

Before you start using Revenue Online for annual reconciliations, you must register to be a Withholding Submitter. Instructions for how to do this are above. After your submitter name and information are approved, you can use either of these to submit your withholding statements.

Step 1 

Look for the "Withholding" menu panel on the Revenue Online homepage, then click on the link “Submit Year-End Withholding.”

Step 2a

Select "Submit a Manual Withholding File," then type in data for each W-2, 1099, or W-2G recipient.

With manual entries, you may save your work in Revenue Online and come back later if you are interrupted.

• When you save, be sure to write down the 6-digit Filing ID from the confirmation screen so you can find your entry again.
• When you come back, on the Revenue Online homepage, go to the "Return Actions" menu panel and click "Search for a Saved or Filed Return".
• Enter your email address and the 6-digit confirmation number
• Click "Submit"

OR

Step 2b

Select "Submit a Withholding File Attachment," then attach your CDOR-EFW2 file or IRS Withholding file. For W-2s, the electronic file must be IRS Format 1220 or CDOR-EFW2. The RA record on the file must match what you enter as the Submitter Information in Revenue Online.

Step 3

Follow the prompts in Revenue Online and click "Submit."

Step 4

After you submit the data, you will receive a confirmation code once your submission is processed. 

Step 5

Print the confirmation page and keep it in your records.

Employers or payroll companies acting on behalf of employers may use Revenue Online to manage the withholding tax account.

1. Go to Revenue Online and log in.
2. Once you are logged in to Revenue Online, scroll to the specific tax account you want to view (WTH for withholding).
3. Click “File/Amend and View Returns/Payments” in the “Account” menu panel.
4. You will see all of the filing periods for that tax type, including links to returns you have already filed and links to returns that should be filed.

Withholding taxpayers submitting 1099 and W-2G forms must contact the Department by telephone to discuss their accounts.
