Third Party Access

What is the difference between the owner and third party access type?

An owner who registers for a username and password as the business owner will receive access to all accounts registered to them. A third party receives access on an account-by-account basis. This means that a third party must request access to each account they need to manage online.

Both owners and third parties, depending on access level, will have the ability to manage accounts and create secondary logons. The Third-Party Non-Administrator access type will not have the ability to add a secondary logon.

I am the business owner; how do I modify the access type for my third party?

  1. Log in to your online services profile using your username and password by visiting the CDTFA website at onlineservices.cdtfa.ca.gov.

  5. Under I Want To, select Manage access
  6. Select the access type to update:

    General Access:

    • Third-Party Administrator — able to create secondary logons
    • Third-Party Non-Administrator — unable to create secondary logons

    Account access

    • All Access — to perform all functions on the account
    • File and Pay — to file returns and make payments on the account, as well as view account information
    • File Returns — to file returns on the account (excluding renewals), as well as view account information
    • Make Payments — to make payments on the account, as well as view account information
    • View — to view the account only
  7. Update and save the submission

If I provide my third party delegate with the security code from the letter, what does All Access allow them to do?

All Access allows them to:

  • File a tax or fee return
  • Make a payment
  • View return and payment history
  • Access a saved draft of a tax or fee return
  • Save banking information for future payments
  • View and obtain correspondence and billings
  • Update account information

Secondary Access

Can I delegate access to an employee to access my portal on my behalf?

Once a business owner or third party has gained access to the account(s), they will have the ability to grant access to secondary users without any additional security code requirements. An email address is required, and you will be prompted to create a username for the secondary user.

The secondary user will only have access to accounts that a business owner or third party has granted them. Based on the access level granted, the secondary user may be able to file returns, make payments, update addresses, etc. If you cancel your user logon at any time, all associated secondary user logons will also be cancelled.

A power of attorney allows an account owner to be represented by legal counsel, Certified Public Accountant (CPA), Enrolled Agent (EA), or another representative.

To complete the power of attorney, you will need the following account owner information:

  • Account number
  • Identification type (for example, a social security number or California Secretary of State entity number)
  • Identification number (for the identification type above)
  • Tax or fee year(s) or period(s) you will be representing

How do I know my request was approved?
