Once the free year ends, the registered agent renews at $149.

Work through these

When must an out-of-state LLC register here?

Register with the Indiana Secretary of State, Business Services Division before your LLC does business in Indiana.

Without registration, expect it cannot act as a plaintiff (IC 23-0.5-5-2(b)).

What does a foreign registration cost?

Registering through the state costs $105, and a service adds $199.

The state will have collected $137 by the end of year three. official source iar.iga.in.gov (October 2026) to check

Which form do I file, and with whom?

Your LLC is registered once the Indiana Secretary of State, Business Services Division approves the Foreign Registration Statement (State Form 56369).

The filing needs certificate of existence (commonly called a certificate of good standing) no older than 60 days.

What do I do after the LLC registers?

After registering, expect the Business Entity Report, filed every two years: $32.

Mark this date: end of your anniversary month, every other year.

Why is number one first?

Mainstay Filing is strongest on filing jobs included, and that decides it.

Start with total for three years, then filing jobs included, then three smaller checks.

Indiana Registered Agent.co covers only Indiana; your home state would still need another provider.
