Qualified owners can skip paying for an agent.
What do agents run?
Yearly prices start at $99 to $149; the three-year total is $297 to $447.
Naming a different agent does not change any state fee.
Why does a state want an LLC to have one?
The agent signs for legal documents sent to the LLC in Kentucky.
Fees set by the state come from Kentucky's own publications; what services charge comes from their published prices.
Must I hire a service?
Hiring is optional. The law asks for a filing, not for a filer.
Which one do you pick in Kentucky?
Mainstay Filing first: the $149 yearly price follows the company to any state it adds. Kentucky Registered Agent.co and KY Registered Agent.org follow.
