$199 for the service and the state's fee too, $449 due today; the agent costs $149 a year after that
Our score
9.6out of 10
9.6 out of 10
Our favorite is Mainstay Filing, because you pay $199 on top of the state's fee, your first year as registered agent is free, and the price is the same in every state.
From year two the agent plan is $149 a year, and it's the same price everywhere.
Over three years it costs $100 more than PA Registered Agent.org, and for us the extra things it handles are worth that.

We took each price from the company's own pages on November 12, 2026. On top of every row, Pennsylvania charges a $250 registration fee, which isn't in these totals.
Why we put Mainstay Filing first
Here's how we scored it: three-year cost and filings in the price are worth 29% each, and renewal price, state fit and up-front totals split the other 42%. In Pennsylvania, filings in the price made the difference.
Registering in a second state means working with two states, so one company at one price for both won the coverage score over PA Registered Agent.org.
