What is inside the $199 package

The package covers the formation filing, a year of registered agent service and the yearly state report in every state that has one. That is 44 states. Checkout shows state fees at cost before you pay. Whatever the state or entity type, the service price stays the same. Alabama, Arizona, Missouri, New Mexico, Ohio and South Carolina do not ask for a yearly LLC report, so in those states the package covers formation and the agent.

The agent-only plan: $149 a year

If the company already exists, the agent plan alone is $149 a year and renews at $149. Extras on the plan: papers served on the company are scanned and uploaded the same business day at no charge, the first three government letters each year are scanned free and compliance reminders. Annual report filing belongs to the formation package; the agent plan leaves it with you.

Adding another state: $199 plus the state fee

Registering an existing company in another state costs $199 plus that state's fee; the agent is free in year one and $149 a year after.
