How to Start an LLC in Indiana: A Step-by-Step Guide (2027)

How to Start an LLC in Indiana (Quick Answer)

To start an LLC in Indiana, file the Articles of Organization through INBiz, Indiana's online business services portal, and pay the $95 state filing fee. Once the state approves it, your LLC legally exists, and from then on it files a Business Entity Report every two years, due by the last day of its anniversary month, for $32 online.

First-year cost: $95 if you file the Articles of Organization yourself. If you are not based in Indiana, add a registered-agent service, commonly $35 to $300 a year, plus an optional $10 name reservation.

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.
• Not ready to file yet? Lock the name down anyway. A $10 online reservation through INBiz keeps that name off-limits to everyone else for 120 days while you sort out the rest.
• 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.

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 3.5: Draft an Operating Agreement

An operating agreement is an internal document that spells out how the LLC is owned and run: member responsibilities, profit and loss splits, voting rights, and what happens if a member leaves. Indiana doesn't require you to file this with the state, and it isn't a public document.

• It's optional on paper, but not in practice. Without one, a dispute between members falls back on Indiana's default LLC statute, which may not reflect what anyone actually intended.
• Banks often ask for it when you open a business bank account, even for a single-member LLC.
• It reinforces your liability protection by showing the LLC is run as a separate entity from its owners, not as an extension of a personal bank account.

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 4.5: Open a US Business Bank Account

Once you have your EIN, the next practical step is separating business money from personal money. Most banks require the same core documents to open a business account: your Articles of Organization (or the state's confirmation of filing), your EIN letter from the IRS, and your operating agreement.

• Keeping funds separate protects your liability shield. Mixing personal and business money, sometimes called "commingling," is one of the fastest ways to undermine the liability protection an LLC is supposed to provide.
• It simplifies bookkeeping and taxes. A dedicated account makes it far easier to track deductible business expenses come tax time.
• Some banks accommodate remote founders. Foreign founders without a US address sometimes need to work with a bank that supports remote account opening, since not every institution does.

Step 5: File Form 5472 if the LLC Is Foreign-Owned

This is the step most Indiana-focused guides gloss over, and it's the one that can cost you the most if you skip it. Own 25% or more of a single-member LLC as a foreign person, and the IRS wants Form 5472 every single year, whether or not the business took in a dollar.

• It doesn't stand alone. You attach it to a pro forma Form 1120, a corporate return that exists just to carry the 5472, even when the LLC has no separate federal corporate tax bill of its own.
• It's a record of money movement. The form documents what passed between the LLC and its foreign owner, from capital put in to payments made for services.
• Inactivity doesn't excuse it. An LLC sitting quiet with no revenue still owes the filing.

Skip it or file late, and the IRS's floor for the penalty is $25,000, assessed per form, per year. Nothing about this obligation is unique to Indiana; a foreign-owned single-member LLC faces it no matter which state it's formed in.

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.

Indiana LLC Costs Breakdown

Indiana is one of the cheaper states to form and keep an LLC in, and the online path is both the faster and the less expensive one. There is no separately confirmed expedited tier to buy, so the figures below are the whole picture.

How Long Does It Take to Form an LLC in Indiana?

Indiana is fast by default. Articles of Organization filed online through INBiz typically clear in about one business day, while a mailed filing takes 5 to 7 business days and costs $100 instead of $95. There is no separately confirmed expedited tier, so online filing is already the fast path.

There is also no newspaper publication step to clear in Indiana, which is what adds cost and delay in the handful of states that still require it. Once INBiz approves the filing, the LLC legally exists.

The EIN is usually the longer wait. SSN or ITIN holders apply online and typically have the number the same day. Founders without either file Form SS-4 by phone, fax, or mail and should expect longer, since an incomplete form means starting the wait over.

The bank account follows both, because banks want the Articles of Organization and the EIN letter together.

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.
• Thinking no revenue means no Form 5472: a 25%+ foreign-owned LLC owes this filing every year regardless of how much, or how little, business it did.
• 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.

FAQ

How much does it cost to start an LLC in Indiana?

Filing the Articles of Organization costs $95 online or $100 by mail. A name reservation, if you want one, is an additional $10. Beyond formation, a registered agent service typically runs $100 to $300 a year if you don't have an Indiana address yourself, and the EIN is free directly from the IRS.

Does Indiana require an annual report for LLCs?

No. Indiana requires a Business Entity Report every two years, not annually, due by the last day of the LLC's anniversary month. It costs $32 online or $50 by mail. There's no monetary late fee for a missed deadline, but 60 or more days past due can lead to a notice and eligibility for administrative dissolution.

Do I need to publish a notice to form an LLC in Indiana?

No. Indiana doesn't require publishing a notice of LLC formation in a newspaper, unlike a handful of other states. Once your Articles of Organization is approved through INBiz, typically within about one business day online, your LLC legally exists without any additional publication step.

Can a non-US resident form an LLC in Indiana?

Yes. The steps above are the same ones a US-based founder follows, with two places where being outside the US changes the process. The first is the registered agent: Indiana Code 23-0.5-4 requires a physical Indiana street address, and a PO box does not qualify, so most foreign founders use a commercial registered agent service.

The second is the EIN. The IRS online tool needs an SSN or ITIN, so founders without either apply on Form SS-4 by phone, fax, or mail. If the LLC is 25% or more foreign-owned with a single member, Form 5472 is then due every year, even at zero revenue.

Can a non-US resident start an LLC in Indiana?

Yes. Indiana sets no residency or citizenship requirement to own an Indiana LLC. You'll still need a registered agent with a physical Indiana street address, which usually means a paid service if you're not in the state. Because you won't have an SSN, you apply for your EIN on Form SS-4 by phone, fax, or mail instead of the online tool. If your LLC is single-member and 25% or more foreign-owned, you also file Form 5472 with the IRS every year, even at zero revenue, or risk a $25,000 minimum penalty.

What are the annual filing requirements for a single-member LLC in Indiana?

Indiana is lighter than most states here: instead of an annual report, every Indiana LLC files a Business Entity Report every two years, due by the last day of its anniversary month, for $32 online or $50 by mail. There's no monetary late fee on its own, but 60 or more days past due makes the LLC eligible for administrative dissolution. A single-member LLC that is 25% or more foreign-owned also has a federal obligation: Form 5472, filed yearly with the IRS even in a year with no revenue, or the $25,000 minimum penalty applies.

Does an Indiana LLC pay income tax?

Yes. Indiana applies a flat state income tax, set at 2.95% for 2026, down from 3.0% the prior year, and the rate has been stepping down annually. For a typical LLC, that income passes through to the owner's personal return rather than being taxed at the entity level. Counties can add their own local income tax on top, ranging from about 0.50% to 3.15% depending on where the LLC operates, so confirm the current figures with the Indiana Department of Revenue.
