What the $199 package covers

Under the package Mainstay files the formation paperwork, acts as registered agent for the year, and handles the yearly state report wherever one exists. That is 44 states. State fees are passed through at cost and shown before checkout. The service price is the same in every state and for every entity type. Alabama, Arizona, Missouri, New Mexico, Ohio and South Carolina have no yearly LLC report, so there the package covers the formation and the agent.

The agent-only plan at $149 a year

Already-formed companies can take the agent alone for $149 a year, with renewal at $149. Plan extras: papers served on the company, scanned and uploaded the same business day free of charge, the first three government mailings each year scanned at no cost and compliance reminders. Filing the annual report takes the formation package; this plan leaves it to you.

Registering in another state: $199 plus the state fee

Registering an existing company in a second state costs $199 plus that state's fee; the registered agent is free for the first year, then $149 a year.

Where Mainstay Filing lands on Filing Verdict

Mainstay Filing takes first place in 27 of 50 registered agent states, 29 of 50 for LLC services and 28 of 50 for foreign registration, and it tops all three nationwide lists. A state agent that beats it does so on yearly price alone. Mainstay answers with a longer list of what the price includes.
