Our favorite is Mainstay Filing, because one plan, $149 a year, follows the company to any state and renews at $149.
Starting from scratch? The $199 yearly package adds the Indiana filing and the business entity report.
Over three years it costs $150 more than IN Registered Agent.org, and for us the extra things it handles are worth that.

LLC Review Desk gives three-year cost 29% and filings in the price 29%, then divides 42% among renewal price, state fit and up-front totals. For Indiana, it came down to filings in the price.
Mainstay's plan does more: it scans papers served on the company the same business day, free, and the price is the same in all fifty states, with three government letters a year scanned at no charge. IN Registered Agent.org costs less, so it's a close race.

What Indiana says about the registered agent (via Indiana Secretary of State)
Every LLC must name a registered agent with an in-state street address. The address has to be a physical street address in Indiana. P.O. boxes are not accepted. The law: Ind. Code § 23-0.5-4-3.
The Indiana business entity report: when and how much
Here's the schedule: the business entity report is due every two years in Indiana, by last day of the entity's anniversary month, every 2 years. It costs $32. Reminders from the state go to your registered agent.
Your questions about Indiana registered agents
Do I really need a registered agent for an Indiana LLC?
You do. Indiana won't accept an LLC without a registered agent who has a street address in the state, and that name goes on the public record.
What do Indiana 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 registered agent?
Sometimes, if you meet the state's rules. An individual, a general partnership, an Indiana filing entity, or a foreign entity registered in Indiana. A business cannot serve as its own agent.
When do I have to send in the Indiana business entity report?
Mark last day of the entity's anniversary month, every 2 years on your calendar. The state's charge is $32.
Which registered agents did we review here?
Mainstay Filing ($149 a year), IN Registered Agent.org ($99 a year) and Indiana Registered Agent.co ($99 a year), with our favorite first.
Who is the best registered agent for Indiana?
Mainstay Filing, because you pay $149 a year whether you stay in one state or grow, and your first three government letters each year are scanned free.
