Researched and written by the Launchwise Review editorial team
Mainstay Filing sells a formation package at $199 a year, renewing at $199. One price gets the LLC formed, a registered agent on the job and the annual report filed, and your EIN application is part of it. Need only the agent? That plan is $149 a year and renews at $149.

Inside the $199 package

The package files the formation, covers a year of registered agent service and files the yearly state report wherever a state asks for one. That is 44 states. You see state fees at cost before you check out. The service price stays the same in every state, whatever the entity type. Alabama, Arizona, Missouri, New Mexico, Ohio and South Carolina ask for no yearly LLC report, so in those states the package pays for formation and the agent.

The $149 agent-only plan

If the company is already formed, you can buy the agent plan alone for $149 a year; it renews at $149. Perks on the plan: scans of papers served on the company arrive the same business day at no charge, your first three government letters each year come as free scans and compliance reminders. Annual report filing comes with the formation package, not this plan.

Opening in another state: $199 plus the state fee

Bringing an existing company into another state costs $199 plus that state's fee; the agent is free for year one, then $149 a year.
