Service Year one Year two Year three Bill over three years Agent covered in year one
Pennsylvania Registered Agent.co $199 $99 $99 $397 Included
Mainstay Filing $199 $149 $149 $497 Not stated
PA Registered Agent.org $199 $99 $99 $397 Included

Why it falls this way

Here is the weighting: 33% for spend over three years, 33% for work the price removes, 34% spread over what renewal looks like, fit with the state and plain price display. In Pennsylvania, spend over three years made the call.

Pennsylvania Registered Agent.co comes to $397 over three years, $100 less than Mainstay Filing. Both include a first year of agent service, so the renewal price made the call.

What it costs to ignore Pennsylvania registration

Until it registers, an outside LLC has no right to sue in Pennsylvania courts (15 Pa.C.S. 411(b)). The contracts it signs stay good (15 Pa.C.S. 411(c)).
