LLC Review Desk's 2026 picks for foreign registration services in Kentucky, favorite first, are Mainstay Filing ($199), KY Registered Agent.org ($199) and Kentucky Registered Agent.co ($199). Mainstay Filing is our favorite, because you pay $199 on top of the state's fee, your first year as registered agent is free, and the price is the same in every state.

Our favorite is Mainstay Filing, because $199 gets the Kentucky registration filed, year one as registered agent costs nothing, and after that it's $149 a year.

Once year one is over, you pay $149 a year for the agent, whichever state you picked.

Over three years it costs $100 more than KY Registered Agent.org, and for us the extra things it handles are worth that.

What Kentucky foreign registration services cost in 2026: year one, renewals and three years

ServiceFirst yearSecond yearThird yearThree-year totalAgent covered in year one
Mainstay Filing$199$149$149$497Free
KY Registered Agent.org$199$99$99$397Included
Kentucky Registered Agent.co$199$99$99$397Included

We took each price from the company's own pages on November 12, 2026. On top of every row, Kentucky charges a $90 registration fee, which isn't in these totals.

Why we ordered them this way

Here's how we scored it: three-year cost and filings in the price are worth 29% each, and renewal price, state fit and up-front totals split the other 42%. In Kentucky, filings in the price made the difference.

Registering in a second state means working with two states, so one company at one price for both won the coverage score over KY Registered Agent.org.

You can read every criterion and weight on How we rank.

Registering a foreign LLC in Kentucky: fee, form and who to send it to

You register through the Kentucky Secretary of State, Division of Business Filings, using the Certificate of Authority (Foreign Business Entity) (Form FBE). The state charges $90.

After that, plan on the annual report each cycle ($15) by between January 1 and June 30 each year.

Get these ready first

  • Your company's full legal name, exactly as registered at home, and the date it was formed there.
  • A registered agent with a street address in the state. Any service on this page can do it.
  • The $90 state fee to pay with the filing.
  • A reminder for yourself about the annual report and its $15 fee.

What happens if you skip Kentucky registration

Until it registers, an out-of-state LLC can't sue in Kentucky courts (KRS 14A.9-020(1)). A $2 daily penalty can apply.
