Removing Access for Designated Users From Your Account
  1. Log in to the account in Revenue Online. On the top of the screen, click "Manage My Profile"
  2. Click “More…"
  3. From here, click on the link "Manage Secondary Log-ons" from the "My Users" menu.
  4. Select the username that you wish to remove access.

  6. Then, you will be asked to confirm that you wish to cancel access for that user.
  7. Click "Yes" to remove access, or "No" to cancel your action.
  8. You will return to the "Manage My Secondary Log-ons" screen for the username that was deactivated.
  9. For a deactivated account, the only hyperlink action available for the Username is "Reactivate Access".  
  10. When you return to the "Manage Secondary Log-ons'' screen, the deactivated Username will still appear in the secondary logons list. The text will now be gray instead of blue, showing that it is no longer active. 

Users, by default, are only given access to the account that they validated against when they originally signed-up. 

For Full-Access users, all accounts related to the setup that were confirmed when setting up the initial logon will be listed on your home page after you have logged in. Only Full-Access users can give users access to additional accounts.  

Click on the link "Add access to this account" for each listed account that you would like access to. 

Note: If you do not see your account listed, it does not mean that the account does not exist.

When you receive a message about your taxes from the Colorado Department of Revenue, the letter has a "Letter ID" in the upper right corner of the page. The ID number starts with the letter "L."

You may use the Letter ID as a security key to set up the way into your account in Revenue Online.  You will then create a Username and Password that you will use each time you open Revenue Online. 

New PIN numbers for Revenue Online are no longer given out by the Department. Older versions of the Revenue Online portal did assign a PIN for tax account access.  You may be able to use the PIN for Revenue Online access if you still know it.

Note: The Letter ID is connected to a particular tax type. You will not be able to use a Letter ID from one letter about tax type for a different tax type. For example, you cannot use a Letter ID from a message regarding your sales tax account to set up an income tax account.

You will need a Security Code to log into Revenue Online for the first time. The two-step verification requires a Security Code each time you log in, unless you adjust the two-step verification settings in your account. 

After the first time you log in, you can adjust the two-step verification settings to support many security code delivery options or you can disable two-step verification. 

The first time you log into your Revenue Online account you will be prompted to set your Security Code delivery preferences. These preferences can be updated at any time when you are logged into Revenue Online. 

Note: If you selected to receive your Security Code by email, be sure to check your email Inbox and Junk or Spam email folders.

To create a Username and Password to access your account in Revenue Online, you will need the following information:

  • Social Security Number (SSN), Individual Taxpayer Identification Number (ITIN), or Federal Employer Identification Number (FEIN)
  • Valid email address
  • Zip code of your residency location
  • Federal adjusted gross income amount on
  • Last filed return or PIN or recent Letter ID
  • Dollar amounts from your tax return(s)
