Before you start
- If you have not done so, you will need to register online on the Philadelphia Tax Center. To register you will need the contact information for your business and the Federal Entity Identification Number (EIN) or Social Security Number (SSN) that the business is under.
- If you are registered, you will need to log in with your username and password in order to file. You can pay as a guest without a username and password by selecting an option under the “Payments” panel on the homepage.
IMPORTANT UPDATE: You must now file and pay this tax electronically on the Philadelphia Tax Center. You can file electronic returns for this tax going back six years. Any returns before 2015 must be filed on paper.
