What Kansas says about the resident agent (via Kansas Secretary of State)
Every LLC must name a registered agent with an in-state street address. The address has to be a Kansas address where the agent is regularly present. P.O. boxes are not accepted. The law: K.S.A. 17-7925.
The Kansas information report: when and how much
Here's the schedule: the information report is due every two years in Kansas, by 15th day of the 4th month after tax-year-end. It costs $90. Reminders from the state go to your resident agent.
Your questions about Kansas registered agents
Do I really need a resident agent for a Kansas LLC?
You do. Kansas won't accept an LLC without a resident agent who has a street address in the state, and that name goes on the public record.
What do Kansas 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 resident agent?
Sometimes, if you meet the state's rules. The company itself, a Kansas resident, or a business entity formed in Kansas or authorized to do business there.
When do I have to send in the Kansas information report?
Mark 15th day of the 4th month after tax-year-end on your calendar. The state's charge is $90.
Which registered agents did we review here?

Who is the best registered agent for Kansas?
