How much does an agent cost?
Our picks charge $99 to $149 annually, and three years total $297 to $447.
Whichever agent you pick, the state's fees stay the same.
What does an agent do for the LLC?
Any legal notice meant for the company lands at its Kentucky agent first.
Papers that arrive with nobody to sign for them can let a case go forward without your LLC. Service of process, explained
Is anything else due every year?
One filing keeps coming back: the annual report, each year, for $15. The state says it is due on or before June 30. The minimum tax is billed separately.
How was the bottom line figured? Add the filing fee, the next two reports and the minimum tax if the state has one. Anything with no fixed price, a newspaper notice for instance, is described above and kept out of the sum.
Still wondering?
Is it allowed to name myself?
Yes, provided you meet the state's rules on who may serve and on the address, both laid out above.
What address does an agent need?
The address has to be a physical registered office in Kentucky that matches the agent's business address. A P.O. box is not enough.
How do the three-year totals compare?
For three years you would pay $447 at Mainstay Filing, $297 at Kentucky Registered Agent.co, $297 at KY Registered Agent.org
Where do these numbers come from?
State fees come from Kentucky's official documents, and service fees come from each company's own pricing page. Both carry dates on this page.
Does the law require a service?
Not at all. The state takes filings from owners directly. A service just saves you time, and it can double as your agent.
What is the best registered agent for Kentucky?
Mainstay Filing, because a single account at $149 a year works in whichever state the LLC registers. After that, Kentucky Registered Agent.co and KY Registered Agent.org.
