#1First choice
1. Mainstay Filing: best for LLCs adding more states
$199 to register, $149 for the agent after
Mainstay Filing is our answer because it asks $199 plus state fees and waives the resident agent charge for the first year.
Choosing KS Registered Agent.org saves $100 over three years, but only a Kansas company can use it.
The resident agent is free in year one, then $149 a year, in any state.

What registers the LLC?
The LLC is registered once the Kansas Secretary of State, Business Services Division accepts the Application for Registration, Foreign (non-Kansas) Business (Form FA).
There is nothing to attach from the home state.
Is there a recurring filing?
Each cycle brings another Information Report, billed at $90.
The schedule says April 15, every second year.
What decided the ranking?
Paperwork covered, worth 29%, put Mainstay Filing first.
The two heavy tests are three-year price (36%) and paperwork covered (29%); three lighter tests follow.
Two states, one provider: that is why it is first.
Every figure above links to its official source; the last line is our own addition of the filing, two reports and any minimum tax, with variable costs such as publication left out.
More quick questions
Does my home state still want an agent?
Yes: two states, two sets of rules. One-state services stop at the border; Mainstay Filing does not.
Official Kansas documents supply the state fees, and the companies' own price pages supply the service fees. Every figure carries a date.
Must I hire a service?
No. What you pay a service covers the labor and the agent role, not anything the state demands.
Can I hire someone to register?
Every company on this page handles the filing for you; the state charges the same regardless.
Which foreign registration service should I hire in Kansas?
Mainstay Filing leads because $199 on top of the state fee gets you registered, with the resident agent free in year one and $149 a year afterward; KS Registered Agent.org come next.
