Our pick
KY Registered Agent.org, Mainstay Filing then Kentucky Registered Agent.co
2. Mainstay Filing: best for owners who want upkeep handled
Annual price $199, renewal price $199, state fee on top
Mainstay Filing takes second place: one yearly price of $199 pays for forming the LLC, serving as the registered agent and filing the annual report, then renews at $199.
KY Registered Agent.org adds up to $200 less over three years, enough to earn the better spot.
The annual report gets filed by Mainstay Filing, and Kentucky's $15 is passed on at cost.
Read on November 13, 2026; three years means year one plus two renewals.
Questions owners ask
How much should I budget to form an LLC here?
The state charges $40, and a service that files for you in year one adds $199.
Over three years the state collects $595, filing fee included. sos.ky.gov, read in October 2026 for this answer
Limited Liability Entity Tax: a $175 minimum each year to the Department of Revenue.
What do I actually send the state?
Send the Articles of Organization - Profit Limited Liability Company (Form KLC) to the Kentucky Secretary of State; approval of that one filing is what creates the LLC.
Every LLC must name a registered agent with an in-state street address.
A Kentucky resident, or an entity qualified to do business in Kentucky, whose business address is the registered office. The agent signs or files a written acceptance.
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.
Nothing stops you. Without a service your three-year bill is the state's $595.
A service adds $397 to $597 across three years, and with Mainstay Filing the reports are inside that figure.
What put number one on top?
On what you pay over three years, worth 33%, KY Registered Agent.org comes out ahead.
We weigh five questions: what you pay over three years (33%), chores the price takes care of (29%), answers on the price page (14%), what happens at renewal (13%) and room to add states (11%).
On cost, KY Registered Agent.org wins at $397, a $200 saving against Mainstay Filing.
Every line above points to the state's own page. The total under them is ours, and it covers the filing, two reports and any minimum tax, nothing that varies by newspaper or county.
