Indiana files a Business Entity Report every two years, not every year, and charges just $32 to do it online. Between the $95 online formation fee and a same-week turnaround, Indiana runs one of the lowest-friction, lowest-admin LLC processes of any state.
That doesn't mean there's nothing to get right. The registered agent requirement, the EIN application for founders without a US Social Security Number, and the Form 5472 obligation for foreign-owned LLCs all still apply in Indiana exactly as they do everywhere else.
TL;DR
- Indiana is a low-cost, low-admin state: $95 to $100 to form, biennial (not annual) reporting, and no publication requirement.
- Step 1, name: confirm your LLC name is distinguishable in Indiana and includes "LLC," "L.L.C.," or "Limited Liability Company."
- Step 2, registered agent: Indiana law (IC 23-0.5-4) requires a physical Indiana street address, not a PO box.
- Step 3, Articles of Organization: file through INBiz for $95 online (about one business day) or $100 by mail (five to seven business days).
- Step 4, EIN without an SSN: the IRS online tool needs an SSN or ITIN, so founders without one apply by phone, fax, or mail using Form SS-4.
- Step 5, Form 5472: a 25%+ foreign-owned single-member LLC must file this annually, even at zero revenue, or risk a $25,000 minimum penalty.
- Step 6, ongoing compliance: the Business Entity Report is due biennially for $32 online, and Indiana's flat state income tax is stepping down year over year.
Why Form an LLC in Indiana
Indiana's appeal isn't a tax break or a legal quirk. It's that the state gets out of the way. Formation costs $95 to $100, online filings typically process in about one business day, and there's no newspaper publication requirement to clear before the LLC is considered active.
The ongoing compliance load stays light too. Most states require an annual report; Indiana only asks for a Business Entity Report once every two years, and the filing fee is a modest $32 online. For a founder juggling formation costs across multiple obligations, that's a real, recurring savings.
None of this changes the federal-level requirements that apply regardless of state: the registered agent rule, the EIN application, and Form 5472 for foreign-owned entities. Those get their own sections below.
Step 1: Choose Your LLC Name
Your LLC name has to be distinguishable from every other business entity already registered in Indiana, and it must include "LLC," "L.L.C.," or "Limited Liability Company."
- Search first. INBiz lets you check name availability before you file anything.
- Reserve it if you're not ready to file. A name reservation costs $10, is filed online through INBiz, and holds the name for 120 days.
- Renewal is available. If your formation timeline slips past 120 days, you can renew the reservation rather than risk losing the name.
Indiana processes name reservations online only, so there's no separate paper option to fall back on if the portal is down.
Step 2: Appoint a Registered Agent
Indiana Code 23-0.5-4-1 requires every LLC to appoint a registered agent, and 23-0.5-4-2 requires that agent to maintain a physical street address in Indiana. A PO box doesn't satisfy this requirement.
Who Can Serve as Your Registered Agent
Indiana law allows several types of registered agents, and the right choice depends mostly on whether you already have an Indiana presence.
- An individual resident of Indiana, such as yourself if you live in-state or a trusted contact who does.
- A general partnership with an Indiana address.
- A domestic filing entity already registered in Indiana.
- A registered foreign entity authorized to do business in Indiana.
Founders without an Indiana address, including most foreign founders, typically use a commercial registered agent service instead of trying to satisfy this requirement themselves.
Step 3: File Your Articles of Organization
The Articles of Organization is the document that legally creates your LLC. In Indiana, it's filed through INBiz, the state's online business services portal.
| Filing method | Fee | Typical processing time |
|---|---|---|
| Online (INBiz) | $95 | About 1 business day |
| $100 | 5 to 7 business days |
Online filing is both cheaper and faster in Indiana, which is unusual; most states charge the same or more for the faster option. There's no separately confirmed expedited tier beyond the standard online turnaround, so online filing is effectively the fast path already.
Indiana also doesn't require publishing a notice of formation in a local newspaper, a step that adds cost and delay in states that still require it.
Step 4: Get an EIN, Even Without an SSN
An Employer Identification Number (EIN) is what the IRS uses to identify your LLC for tax purposes, and it's required to open a US bank account or file taxes. Applying directly through the IRS is free either way.
Founders with a Social Security Number or an Individual Taxpayer Identification Number (ITIN) can apply online and typically receive an EIN the same day. Founders without either have to use a different route.
- File Form SS-4 by phone, fax, or mail instead of the online tool.
- Expect a longer wait than the online applicant's same-day turnaround, since manual processing takes longer.
- Fill it out completely the first time, since an incomplete or incorrect Form SS-4 typically means starting the wait over.
Step 5: File Form 5472 if the LLC Is Foreign-Owned
If your single-member LLC is 25% or more foreign-owned, the IRS requires an annual Form 5472 filing, regardless of whether the LLC generated any revenue that year.
- Filed with a pro forma Form 1120, a placeholder corporate return required alongside the 5472, even though the LLC itself may owe no separate federal corporate tax.
- Reports transactions between the LLC and its foreign owner, including capital contributions and payments for services.
- Applies even when dormant. A low-activity or zero-revenue LLC is not exempt.
The IRS's stated minimum penalty for a late or missing Form 5472 is $25,000, per form, per year. This requirement isn't Indiana-specific; it applies to foreign-owned single-member LLCs in every state.
Step 6: Keep Up With Ongoing Compliance
Indiana's ongoing requirements are lighter than most states, but they still carry real consequences if missed.
Business Entity Report
Indiana requires a Business Entity Report every two years, not annually, due by the last day of your LLC's anniversary month. Filing online costs $32; filing by mail costs $50.
- No monetary late fee applies for a missed deadline on its own.
- 60 or more days past due triggers a state notice and makes the LLC eligible for administrative dissolution, though a cure window is available before that happens.
State Income Tax
Indiana applies a flat state income tax, set at 2.95% for 2026, down from 3.0% the prior year. The rate has been stepping down annually, so founders should confirm the current figure with the Indiana Department of Revenue rather than treating this as fixed. Counties can add their own local income tax on top, ranging from about 0.50% to 3.15% depending on where the LLC operates.
Operating Outside Indiana
An LLC formed in Indiana but doing business in another state may need to foreign-qualify there, filing an Application for Certificate of Authority along with a Certificate of Good Standing no older than 60 days. The exact foreign-qualification fee isn't confirmed here; check the relevant state's Secretary of State site directly before filing.
Common Mistakes to Avoid
- Using a home or a friend's address as the registered agent: it must be a real Indiana street address, and a PO box or an address outside Indiana doesn't qualify.
- Assuming Form 5472 is optional at zero revenue: the filing requirement applies to a foreign-owned LLC whether or not it made a dollar that year.
- Forgetting the Business Entity Report because it's not annual: the two-year cycle makes it easy to lose track of, and 60+ days late risks administrative dissolution.
- Filing by mail to save money: in Indiana, mail filing is both slower and $5 more expensive than filing online.
- Assuming Indiana's tax rate is fixed: the flat rate has been stepping down each year, so a figure from an old guide may already be out of date.
