Our pick
Mainstay Filing, Pennsylvania Registered Agent.co then PA Registered Agent.org
1. Mainstay Filing: best for one price for setup and upkeep
$199 a year and $125 to the state
$199 a year pays for forming the LLC, acting as your registered agent and filing the annual report, and it renews at $199. That's why Mainstay Filing is first.

You won't file the annual report yourself. Pennsylvania still charges $7, billed at cost.

Do I have to name a registered 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.
The last row is our math, not the state's: filing fee, plus the reports in years two and three, plus any minimum tax. If a cost has no fixed amount, like a newspaper notice, it's explained above and left out.
