However, if you are referring to deleting a contact in an Intuit Account. Only the Primary Contact can delete a contact in an Intuit Account. If a Non-Primary contact tries to delete another contact, an error message will appear:

"Additional Action Required

Sorry, you don't have permission to remove this user because you aren't listed as the primary contact on this account. Ask Sam to remove this user, or contact us for more help with this."

To begin, have the primary contact do the following steps:

1. Sign in to CAMPS website.
2. Scroll down to Authorized Users and select the contact that needs to be deleted.
3. Select Remove User to remove the contact.

If the Primary Contact is unable to log in to the CAMPS website, consult Account Escalations.
