The documents below contain step-by-step instructions for third-party tax professionals using the Philadelphia Tax Center. Use the instructions to:

Start using the system.
Request account access from existing taxpayers.
Add clients who are new taxpayers in Philadelphia.

When you request access to an existing or new taxpayer’s accounts, the verification process includes sending a physical letter in the mail. The letter goes to your client’s mailing address. It may take you a week or more to complete the initial setup, but this allows us to protect tax and personal information.
