In order to pay City taxes, you need a Philadelphia Tax Identification Number (PHTIN). To learn more, visit our page on how to get a tax account.
You can visit the Philadelphia Tax Center to open a Philadelphia tax account online. If your business or nonprofit prefers to register by mail, you can use the form on this page.
Nonprofits should include 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.
