Step-by-step lesson
Step1
Step 1: Confirm you need to register
If your LLC was formed outside Pennsylvania and does business there, it needs a foreign registration first. Skipping it has consequences: An unregistered LLC cannot bring a suit there (15 Pa.C.S. 411(b)). Its contracts still stand (15 Pa.C.S. 411(c)).

Step 2: Line up a Pennsylvania registered agent
Pennsylvania requires a registered office (a Pennsylvania street address or a Commercial Registered Office Provider), not an agent. The address has to be an actual street address or rural route box number in Pennsylvania. A P.O. box alone is not accepted.
Pay $250 and file the Foreign Registration Statement (DSCB:15-412) with the Pennsylvania Department of State, Bureau of Corporations and Charitable Organizations.
