Questions, answered plainly

Every LLC must name a registered agent with an in-state street address.

The law behind it: Ind. Code § 23-0.5-4-3. faqs.in.gov, confirmed October 2026

Who qualifies?

An individual, a general partnership, an Indiana filing entity, or a foreign entity registered in Indiana. A business cannot serve as its own agent.

You can be your own agent if you qualify; the state charges nothing extra.

How much per year?

$99 to $149 a year from the services we'd use, or $297 to $447 over three years.

The state charges the same with any agent.

What does the agent actually do?

It accepts court papers and state mail for your LLC at an address in Indiana.

That is why the address must be staffed in business hours. What is service of process?

What does the state charge yearly?

Mainly the business entity report, once every two years. Fee: $32. Deadline: last day of the entity's anniversary month, every 2 years.
