On-line Version of the PA-100 Enterprise Registration Form

PA BIZ Online allows users to register an enterprise electronically with the Commonwealth in two ways; an online interactive interview and an on-line version of the PA-100 Enterprise Registration Form.

The PA On-line Business Tax Registration (PA-100) will assist you in completing all applicable sections that pertain to your enterprise's individual registration needs. The On-line PA-100 may be used to register a new enterprise, add additional taxes or services, or to register a new enterprise that is acquiring all or part of an existing enterprise. 

Note: If you already have a Sales, Use, and/or Employer Withholding tax account, and are attempting to register to file and pay business taxes electronically via the internet, please visit our e-Tides homepage.
If you already have an Unemployment Compensation tax account, and are attempting to register to file and pay UC taxes electronically via the internet, please visit the Department of Labor & Industry’s UCMS homepage.

If you need to register with the PA Department of State, please use the Online Business Registration Interview (OBRI) available at
PA BIZ Online

The On-line PA-100 can also be used to register for other taxes.  However, these registrations must be printed and mailed upon completion of the online process.  See "About On-line PA-100 " for information about other taxes. 

NOTE:  To use the On-line PA-100 you must have the proper browser with 128-bit encryption. If you need to upgrade your browser, click on the Security link.
