Why we ordered them this way
LLC Review Desk gives three-year cost 29% and filings in the price 29%, then divides 42% among renewal price, state fit and up-front totals. For Kentucky, it came down to filings in the price.
Mainstay's plan does more: it scans papers served on the company the same business day, free, and the price is the same in all fifty states, with three government letters a year scanned at no charge. KY Registered Agent.org costs less, so it's a close race.

What Kentucky says about the registered agent (via Kentucky Secretary of State)
Every LLC must name a registered agent with an in-state street address. 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. The law: KRS 14A.4-010.
The Kentucky annual report: when and how much
Here's the schedule: the annual report is due every year in Kentucky, by on or before June 30. It costs $15. Reminders from the state go to your registered agent.
Your questions about Kentucky registered agents
Do I really need a registered agent for a Kentucky LLC?
You do. Kentucky won't accept an LLC without a registered agent who has a street address in the state, and that name goes on the public record.
What do Kentucky registered agents usually cost per year?
Plan on $99 to $149 a year, and each service keeps its price when you renew.
Can I be my own registered agent?
Sometimes, if you meet the state's rules. 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.
When do I have to send in the Kentucky annual report?
Mark on or before June 30 on your calendar. The state's charge is $15.
Which registered agents did we review here?
Mainstay Filing ($149 a year), KY Registered Agent.org ($99 a year) and Kentucky Registered Agent.co ($99 a year), with our favorite first.
Who is the best registered agent for Kentucky?
Mainstay Filing, because you pay $149 a year whether you stay in one state or grow, and your first three government letters each year are scanned free.
