What you probably want to know

Could I skip naming a registered agent?

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

Where the law says so: 15 Pa.C.S. § 8825. legis.state.pa.us, confirmed October 2026 (official)

Who is allowed to be the agent?

Pennsylvania does not require a registered agent. Every LLC keeps a registered office instead: an actual street address in Pennsylvania, or a Commercial Registered Office Provider named in its place by a company without a Pennsylvania address.

Qualify, and the job can be yours for free.

How much does agent service run?

Prices start at $99 to $149 a year, and three years total $297 to $447.

The state charges the same no matter the agent.

What does an agent do for the LLC?

It's the address in Pennsylvania where court papers and state letters get delivered for your LLC.

That's why the address has to be staffed during business hours. What does "service of process" mean?

Does the LLC owe the state anything every year?

Mostly the annual report, once a year, at $7. The state's due date: September 30. Jot that down early.

pa.gov, confirmed October 2026 (official)

How did you decide the order?

Work taken off your hands, worth 31%, put Mainstay Filing first.

33% of the score is cost across three years, 31% is work taken off your hands, and three smaller checks split ties.

Pennsylvania Registered Agent.co costs less, yet it covers only Pennsylvania.

More questions

Can an owner serve as agent?

Yes. This state doesn't require a named agent in the first place.

Which addresses does the state accept?

The address has to be an actual street address or rural route box number in Pennsylvania. A P.O. box alone is not accepted.

What does each one cost over three years?

Mainstay Filing will cost you $447, Pennsylvania Registered Agent.co will cost you $297, PA Registered Agent.org will cost you $297

What do the numbers rest on?

What the state charges comes from official Pennsylvania publications; what services charge comes from what they publish.

Is a filing service a must?

You can skip it. The state's fee is the same whichever way you file.

Start with Mainstay Filing, followed by Pennsylvania Registered Agent.co and PA Registered Agent.org.
