What you need to know
When does an out-of-state LLC have to register?
Do it first, sell second: an LLC from elsewhere signs up with the Kansas Secretary of State, Business Services Division before taking its first Kansas customer.
An unregistered LLC risks Kansas's courts won't hear its claims (K.S.A. 17-76,126(a)).
Add three years of state fees, registration included, and you're at $205. go check sos.ks.gov, last confirmed October 2026
Which form, and who gets it?
You file the Application for Registration, Foreign (non-Kansas) Business (Form FA) with the Kansas Secretary of State, Business Services Division, and that single filing registers the LLC.
The state doesn't ask for a certificate from your home state.
Is there a filing that repeats?
The state wants a Information Report later, and it's $90.
Per the state, it's due April 15, every second year.
Why this order?
On money out the door in three years (35% of the score), KS Registered Agent.org wins.
65% of the score comes from money out the door in three years and jobs the price actually covers.
Mainstay Filing costs $100 more over three years than KS Registered Agent.org, which comes to $397.
The last row is our math, not the state's: filing fee, plus the reports in years two and three, plus any minimum tax. If a cost has no fixed amount, like a newspaper notice, it's explained above and left out.
Still wondering?
Do I still need an agent at home?
Each state sets its own rule, so keep an agent at home too. A provider that works in every state, like Mainstay Filing, can handle both.
What's the three-year damage for each?
KS Registered Agent.org will set you back $397, and Mainstay Filing will set you back $497, before state fees.
Are the fees official?
Official Kansas sources back the state side, and posted prices back the service side.
Do I have to use a service?
No law says you need a service. It's a convenience you pay for.
Can I pay somebody to register the LLC?
Yes. Every pick files it, and the state fee's the same whichever you choose.
Who should I use for a foreign registration service in Kansas?
KS Registered Agent.org is first: $199 files the registration, and from year two the agent's $99. Then comes Mainstay Filing.
