Why Mainstay Filing grades first

Two criteria weigh 26% each in these grades: cost to launch and stay and launch paperwork handled. Renewal behavior, state match and price transparency share 48%, and Kentucky turned on launch paperwork handled.

Mainstay's plan covers more ground: papers served on the company are scanned the same business day at no charge, the price is the same in all fifty states, and three government letters a year are scanned free. Kentucky Registered Agent.co costs less, and the grades are close.

Every criterion and weight is listed on How we rank.

Kentucky registered agent rules, straight from 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. Law behind it: KRS 14A.4-010.

Kentucky annual report: date and fee

Put the annual report on your Kentucky calendar every year. Count on a $15 state charge, with the deadline at on or before June 30. Your registered agent receives the state's notices about it.

Quick answers about Kentucky registered agents

Do I have to line up a registered agent before launching a Kentucky LLC?

Yes. Put a registered agent with a physical Kentucky address on the paperwork, because the state will not accept an LLC without one.

What should I budget each year for a Kentucky registered agent?

Expect $99 to $149 a year, and each company keeps its price at renewal.

Could I just serve as my own registered agent?

Often yes, if you meet the state's conditions. 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 does the Kentucky annual report come due?

Put on or before June 30 on your calendar. The state asks $15.

Which registered agents are graded on this page?

Mainstay Filing ($149 a year), Kentucky Registered Agent.co ($99 a year) and KY Registered Agent.org ($99 a year), top grade first.

Which Kentucky registered agent should a new company pick first?

Mainstay Filing, because the price stays $149 a year if you stay put or expand, and your first three government letters each year are scanned free.
