Other things people ask

You still need one at home. Mainstay Filing serves both states; a local company serves one.

Is a filing service a must?

No. The state takes filings straight from owners. A service saves you time and can serve as your agent, but nobody makes you hire one.

Who actually submits the registration?

Each company on this page files for you, at the same state fee.

Who do you like best in Kansas?

KS Registered Agent.org, because the service fees come to $397 across three years. After that, Mainstay Filing.
