Pennsylvania registered agent rules straight from Pennsylvania Secretary of State (official)

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. The law behind it: 15 Pa.C.S. § 8825.

Pennsylvania's annual report: what it costs, when it is due, who gets the notice

Pennsylvania LLCs send in the annual report every year, due September 30. The state's fee is $7. Notices about it land with your registered agent.

Do you need a registered agent to run a Pennsylvania LLC?

Pennsylvania requires a registered office (a Pennsylvania street address or a Commercial Registered Office Provider), not an agent.

What should you expect to pay a Pennsylvania registered agent?
