What a first-time founder should look for
The three-year cost and the steps handled tell you more than the first-year price does. If the company may ever work in more than one state, coverage across states matters too.
Why this order
Five criteria grade every list, with three-year cost and the number of steps covered at the top. A national list is read by founders in every state, so the provider that works for all of them is graded highest. Places two and three go to Oklahoma Registered Agent.co and MD Registered Agent.org, which charge less if your company lives in Oklahoma or Maryland.
Take the lesson for your state
Each state lesson walks through appointing a registered agent step by step, with that state's official fees and our picks there. Registered agents: all 50 states.
