Visit the Philadelphia Tax Center to open a Philadelphia tax account online for most City business taxes. Continue to use our eFile/ePay website to open other tax accounts until October 2022.

If you’re a business, a tax account number and Commercial Activity License (CAL) are required for any business operating in Philadelphia. Once you have your tax account, you can obtain your CAL from the Department of Licenses & Inspections.

Non-profit groups should register with the Department of Revenue by mailing this completed form with a copy of their IRS 501 (C) (3) exemption letter. Non-profits are not liable for the Business Income and Receipts Tax (BIRT), but may owe other taxes. For example, they must pay the Wage Tax if they have employees.
