How to Start an Indiana LLC: Step by Step

Key Takeaways

• Indiana LLCs are formed by filing Articles of Organization through INBiz, the Indiana Secretary of State’s official online filing portal.
• Online filing is usually faster and cheaper than filing by mail, with a $95 online filing fee compared with $100 by mail.
• Every Indiana LLC must maintain a registered agent with a physical Indiana street address to receive legal and government notices.
• Indiana doesn’t require an operating agreement, but having one helps define ownership, management, voting rights, and member responsibilities.
• After formation, Indiana LLCs must stay compliant by filing a Biennial Business Entity Report every two years and handling any required tax or license registrations.

How to Form an Indiana LLC in 7 Steps

Forming an Indiana LLC comes down to three core elements: a compliant business name, a registered agent with a physical Indiana address, and a completed Articles of Organization submission.

You can't file the Articles of Organization without a confirmed name and a designated registered agent. And you can't complete post-formation registrations without the EIN your approved LLC makes possible.

Step 1: Choose and Check Your Indiana LLC Name

Your Indiana LLC name must include "Limited Liability Company," "LLC," or "L.L.C." Abbreviations like "Ltd." or "Co." alone don't cut it.

The name also has to be distinguishable from every other active business entity name registered in Indiana. Indiana ignores entity-type designators when checking similarity, so swapping "LLC" for "Inc." won't make a taken name available.

Certain words require prior regulatory approval before you can use them in your name.

• Banking words. Terms like "bank," "banker," or "banking" require written approval from the Indiana Department of Financial Institutions.
• Insurance words. Terms suggesting an insurance company require written approval from the Indiana Department of Insurance.
• Corporate entity words. Words like "corporation," "incorporated," "corp.," and "inc." are prohibited because they imply a different legal entity type.

Before filing, run a name availability search in INBiz using the Check name availability tool. The search is a preliminary check only. Availability isn't guaranteed until final processing at filing.

If you need more time, Indiana lets you reserve a name for 120 days for a $10 fee. You can renew for successive 120-day periods through INBiz.

Step 2: Appoint an Indiana Registered Agent

Every Indiana LLC must designate and maintain a registered agent to receive official legal documents, tax notices, and service of process.

The registered agent must be an individual who resides in Indiana, or a domestic or foreign entity authorized to do business in Indiana. The address must be a physical Indiana street address, not a P.O. box. The agent must be available during normal business hours. Registered agent rules in Indiana don't require the agent to file a separate consent form at formation.

You simply list the agent's name and address in the Articles of Organization. That said, confirm the agent's acceptance before listing them. Once named, they take on legal responsibility for receiving and forwarding service of process.

You've got two options: serve as your own registered agent or hire a professional service. Serving as your own agent costs nothing, but your name and address become part of Indiana's public business registry. You also have to be physically present at that address during business hours. Professional registered agent services typically run $80 to $300 per year.

Missing a legal notice because you weren't available can result in a default judgment against your LLC. That's why the privacy and reliability of a professional service is worth the annual cost for most owners.

Step 3: File Your Articles of Organization with INBiz

The Articles of Organization (State Form 49459) is the document that officially creates your Indiana LLC. File through INBiz at inbiz.in.gov or mail the paper form to: Indiana Secretary of State, Business Services Division, 302 W. Washington Street, Room E018, Indianapolis, IN 46204.

Here’s how to file online.

1. Create an INBiz account at inbiz.in.gov.
2. Start a new business filing. Select "Start a New Business" and choose "Limited Liability Company" under "Domestic Entity Type."
3. Complete the Articles of Organization. Provide your LLC name, registered agent's name and Indiana street address, management structure, principal office address, organizer's information, and LLC duration (most filers choose "perpetual").
4. Review and electronically sign your Articles.
5. Pay the filing fee. You’ll owe $95 if you file online and $100 if you file by mail.

Online filings are typically approved within one business day. Your Certificate of Organization is available immediately in your INBiz account under "Filing History." Mail filings take about five business days of processing plus transit, so plan for two to three weeks total.

Always confirm current fees at inbiz.in.gov before filing.

Step 4: Decide on Member-managed or Manager-managed Structure

Indiana's Articles of Organization require you to declare your LLC's management structure before filing. Your choice determines who has legal authority to act on behalf of the business.

In a member-managed LLC, all members take part in day-to-day decisions and have equal management rights unless the operating agreement says otherwise.

In a manager-managed LLC, one or more designated managers (who may be members or outside parties) handle operations. Members in a manager-managed LLC can't bind the LLC simply by virtue of ownership.

Most single-member and small multi-member LLCs choose member-managed. Manager-managed works better when you have passive investors who own a stake but don't want operational responsibility.

Whatever you declare in the Articles must align with your operating agreement. Inconsistency between the two creates confusion and potential disputes.

Step 5: Create an Indiana LLC Operating Agreement

Indiana doesn't legally require an operating agreement, but skipping it is one of the most common mistakes new LLC owners make. Without one, your LLC runs on Indiana's default statutory rules, which rarely fit real businesses.

A well-drafted Indiana LLC operating agreement should cover these points.

• Ownership percentages. Each member's ownership stake.
• Profit and loss allocation. How earnings and losses are divided among members.
• Management roles and voting rights. Who makes decisions, and how votes are weighted.
• Procedures for adding or removing members.
• Dissolution provisions. The steps to wind down the LLC if it comes to that.

A written agreement strengthens the separation between you and the business, which is essential for liability protection. Banks often require it before opening accounts, and investors expect to review it before committing funds.

The agreement must also reflect the management structure declared in the Articles. If you filed as manager-managed, spell out exactly which manager holds what authority. If ownership percentages are unequal and you want voting rights to reflect that, the operating agreement is where you set it up.

Step 6: Get a Federal EIN for Your Indiana LLC

An employer identification number (EIN) is your LLC's federal tax ID. The IRS issues EINs free of charge at irs.gov, and the online application takes about 10 minutes. You can also register your EIN through Inc Authority as part of your formation process.

You need an EIN to open a business bank account, hire employees, and build business credit. Even single-member LLCs with no employees benefit from having one. It keeps your Social Security number off business documents and reinforces the separation between you and your LLC.

Step 7: Register for Indiana State Taxes and Business Licenses

Indiana imposes a 7% sales tax on the retail sale of tangible personal property and certain services. If your LLC sells taxable goods or services, register for a Registered Retail Merchant Certificate (RRMC) with the Indiana Department of Revenue. If you have employees, set up an Indiana withholding tax account. Both registrations are handled through INBiz at no fee. You can also complete Indiana Department of Revenue Form BT-1 online through the DOR's INtax system.

Indiana imposes state income tax on LLC members' distributive shares at the individual level but no franchise tax or annual LLC tax at the entity level. Confirm the current individual income tax rate at in.gov/dor before filing.

Indiana has no single statewide general business license, but many LLCs need industry-specific or locally issued permits. The Indiana Professional Licensing Agency (IPLA) handles licensing for regulated professions including architects, accountants, cosmetologists, dentists, doctors, engineers, nurses, pharmacists, plumbers, psychologists, and real estate agents. Check the IPLA at pla.in.gov before you open. Local county and city governments may also require operating permits, zoning compliance, or health department approvals, so check with your county clerk's office or city hall.

Indiana LLC Filing Fees, State Costs, and Ongoing Compliance Costs

Always confirm current fees through INBiz before filing, since state fees can change. However, you can typically expect to pay the following.

• Articles of Organization. Online: $95. Mail: $100. The difference reflects an Enhanced Access surcharge on online transactions. You pay slightly less by mail but wait significantly longer.
• Name reservation. Optional. At $10 for 120 days, it's only worth doing if you want to lock down your name before you're ready to file.
• Registered agent. $0 if you serve yourself; $80 to $300 per year for a professional service. See Step 2 for the tradeoffs.
• Biennial Business Entity Report. $32 online through INBiz or $50 by mail. Due by the last day of your LLC's anniversary month every two years (State Form 48725). Visit the Biennial report filing page on INBiz to submit online.
• Expedited processing. Not available. Online filings through INBiz are typically processed within one business day, which makes it unnecessary for most filers anyway.

There’s no Indiana franchise tax or annual LLC tax. Your ongoing state compliance costs are predictable: the biennial report fee every two years plus your registered agent.

Total estimated 2-year cost for most first-time filers:

• Articles of Organization (online): $95
• Registered agent service (year 1): $80–$300
• Biennial Business Entity Report: $32 online

Total: $207–$427, depending on your registered agent choice.

Inc Authority's formation service is free. You can start your Indiana LLC for free with Inc Authority and pay only the required Indiana state fees, with $0 in service fees.

How Long Does it Take to Get an Indiana LLC Approved?

Online filing through INBiz is the fastest way to form an Indiana LLC. The online filing fee is $95, and most online filings are approved within about one business day. Once approved, you can download your Certificate of Organization and stamped Articles from your INBiz account under “Filing History.”

Mail filing costs $100 and takes longer. The state typically needs about five business days to process mailed Articles of Organization after receiving them, and mailing time can bring the total turnaround to roughly two to three weeks.

Indiana doesn’t offer expedited processing. If timing matters, filing online is the better option because it is both faster and less expensive. Before you submit your paperwork, confirm current processing times and fees at inbiz.in.gov.

What Can Slow Things Down

High filing volume can extend processing times. More often, errors are the culprit: an incorrect LLC name, an incomplete registered agent address, or a missing management structure declaration will get your filing rejected. You'll need to correct and refile. Double-check everything before you submit.

Expedited processing isn't available through the state. However, online filing already delivers same-day or next-business-day results for most filers.

Always confirm current processing times at inbiz.in.gov before filing.

Indiana Biennial Report and Ongoing LLC Compliance Requirements

Indiana requires every active LLC to file a Business Entity Report every two years with the Secretary of State. Miss it, and your LLC risks administrative dissolution.

State Form 48725, filed once every two calendar years by the end of the LLC's anniversary month. The report updates your LLC's registered agent, principal office address, and the names and addresses of its members or managers.

When It’s Due

The deadline follows your LLC's formation anniversary month. LLCs registered in an odd-numbered year owe reports in their anniversary month during each subsequent odd-numbered year. Even-numbered year registrations follow the same logic in even-numbered years.

For example: an LLC registered March 15, 2022 owes its first report by March 31, 2024, and its next by March 31, 2026.

Calendar your deadline the day your LLC is approved. The Indiana Secretary of State typically sends courtesy reminders to the registered agent about 90 and 30 days before the due date, but don't count on receiving them. Indiana accepts biennial reports during the 90 days before the due month, so use that early filing window.

Cost. $32 online through INBiz or $50 by mail. File online.

What Happens if You Miss the Deadline

Indiana charges no dollar-amount late fee. But if the report isn't filed within 120 days of its due date, the Secretary of State will administratively dissolve your LLC. The consequences are serious:

• Loss of liability protection. Personal assets may be exposed to business debts and lawsuits.
• Loss of name protection. Your entity's name may become available for others to register.
• Inability to conduct business. A dissolved LLC may be unable to enter contracts, maintain bank accounts, or defend itself in Indiana courts.
• Downstream compliance problems. Banks, payment processors, and vendors may cut ties.

Reinstatement is Possible

You'd need to file an application with the Secretary of State, along with a tax clearance certificate from the Indiana Department of Revenue and all back-owed report fees plus a reinstatement fee. The DOR clearance process can take several weeks. Dissolved Indiana LLCs may seek reinstatement within five years. Miss that window and you have to form a new entity entirely.

Filing on time costs $32. Reinstatement costs weeks of effort, multiple fees, and a DOR clearance process.

What Happens After You Form Your Indiana LLC?

Once Indiana approves your LLC, the next priority is making the business ready to operate. That means putting the right financial, tax, licensing, and compliance pieces in place so your LLC stays organized beyond the initial filing.

• Open a dedicated business bank account. Banks typically ask for your EIN, Articles of Organization, and operating agreement. Keeping personal and business finances separate by opening a dedicated business bank account is essential to maintaining liability protection.
• Finalize your operating agreement. If you drafted one before filing, confirm the management structure matches your approved Articles. Haven't drafted one yet? Do it before you take any business actions.
• Register for Indiana state taxes. If your LLC sells taxable goods or services, register for a Registered Retail Merchant Certificate through INBiz. If you have employees, set up your Indiana withholding tax account at the same time.
• Check your business license requirements. Verify licensing requirements with the IPLA at pla.in.gov if your LLC operates in a regulated profession. Check with your county clerk's office or city hall for local permits.
• Calendar your Biennial Business Entity Report deadline. Your first report is due by the last day of your LLC's anniversary month in the second year following formation. The $32 online filing fee is far cheaper than the reinstatement process.
• Consider forming through Inc Authority. Inc Authority's formation service is 100% FREE; you pay only the required Indiana state fees.

Indiana LLC FAQs

How Much Does it Cost to Establish an LLC in Indiana?

Filing the Articles of Organization costs $95 online or $100 by mail. Beyond formation, budget for a registered agent ($0 DIY, or $80 to $300 per year for a professional service) and the Biennial Business Entity Report ($32 online every two years). Indiana imposes no franchise tax or annual LLC tax at the entity level. Confirm current fees at inbiz.in.gov before filing.

What is Required to Get an LLC in Indiana?

Three things: a compliant LLC name (including a required designator such as "LLC"), a registered agent with a physical Indiana street address, and a completed Articles of Organization filed through INBiz or by mail. An operating agreement isn't required to form the LLC, though drafting one before filing is strongly recommended.

Is Indiana a Good State for an LLC?

Yes. Indiana imposes no franchise tax or annual LLC tax at the entity level. The $95 online filing fee is low, the formation process through INBiz is straightforward, and the biennial report obligation ($32 online every two years) is among the least burdensome ongoing compliance requirements of any U.S. state.

What Are the Downsides of Starting an LLC in Indiana?

LLC members pay self-employment taxes on their share of business income, and the structure requires ongoing administrative upkeep. Indiana-specific obligations include maintaining a registered agent, filing the Biennial Business Entity Report every two years, and the risk of administrative dissolution if that report is missed. These are manageable but real costs that a sole proprietorship doesn't carry.

Can I Be My Own Registered Agent in Indiana?

Yes, provided you have a physical Indiana street address and are available there during normal business hours. The tradeoff: your name and address become part of Indiana's public business registry, and missing a legal notice can result in a default judgment against your LLC. Inc Authority offers a FREE year of Registered Agent Service with your LLC formation. Most owners with privacy concerns or variable schedules use a professional service instead.

Do I Need to Renew My Indiana LLC Every Year?

No. Indiana requires a Biennial Business Entity Report every two years, due by the last day of your LLC's anniversary month in each applicable year. It costs $32 to file online through INBiz. Missing the deadline by more than 120 days triggers administrative dissolution.
