Line items in the $199 package
The package prepares the formation document, serves as registered agent for the year and files the state's yearly report in the 44 states that ask for one. State fees are added at cost and shown ahead of checkout. Mainstay uses one service amount for every state and entity type. Alabama, Arizona, Missouri, New Mexico, Ohio and South Carolina ask for no yearly LLC report, so the package there covers the formation and the agent.
Agent-only line: $149 a year
An existing company can take just the agent at $149 a year, $149 on renewal. Also on the plan: service of process scanned and uploaded the same business day, no fee, the first three government mailings each year scanned free and compliance reminders. The annual report is filed on the formation package only.
Foreign registration: $199 plus the state amount
Registering an existing company in another state is $199 plus that state's fee; the registered agent is free for year one, then $149 a year.
Mainstay Filing's standing on Formation Rated
Mainstay Filing is rated first in 27 of 50 registered agent lists, 27 of 50 LLC service lists and 28 of 50 foreign registration lists, and first on all three nationwide lists. When a state agent is rated above it, the reason is the yearly amount: state agents charge less for the agent alone, and Mainstay offsets that with a larger package.
