Application to open a Philadelphia tax account

Visit the Philadelphia Tax Center to open a Philadelphia tax account online.

If you’re a business, you’ll need a tax account number and Commercial Activity License (CAL) to operate in Philadelphia. Once you have your tax account, you can get your CAL.

Nonprofit groups should register with the Department of Revenue by mailing this completed form with a copy of their IRS 501(c)(3) exemption letter. Nonprofits aren’t 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.
