How to Start an Indiana LLC — Step by Step

Your LLC name has to be distinguishable from every other business name already registered in Indiana. That is a legal test, not a gut feeling — a name that differs only in punctuation, spacing, or a filler word like "the" may still collide with an existing entity and get your filing bounced.

Start at the Indiana business name search. Run your proposed name and a few close variations. If something already on file reads or sounds too similar, adjust before you file rather than after — a rejection costs you days.

Naming rules to respect

• The name must include "Limited Liability Company," "LLC," or "L.L.C."
• It cannot imply the company is a government agency.
• Restricted words — those suggesting banking, trust, or insurance activity — need clearance from the relevant Indiana regulator before you can use them.
• It must be distinguishable from all active names in the Secretary of State's database.

Holding a name before you file

Not ready to file yet but worried someone will grab your name? Indiana lets you reserve an available name for a limited window through the Secretary of State. Reservation does not create the LLC; it just parks the name while you sort out the rest.

Before you can file the Articles of Organization, you need a registered agent lined up, because the agent is named right in the filing and has to consent to the role.

Indiana requires every LLC to keep a registered agent with a physical Indiana street address for the life of the company. This is the party that receives lawsuits, subpoenas, and official state notices on the LLC's behalf.

Who can serve

• You — if you have a physical Indiana street address (not a P.O. box) and are reliably around during business hours. Your address then appears in the public record.
• Another individual — any Indiana resident with a street address in the state: a co-owner, an employee, or an attorney.
• A commercial registered agent service — a business licensed to serve as an agent within Indiana. It keeps its own address on the public record instead of yours and makes sure someone is always available to accept documents.

Why the choice is not trivial

Whatever address you list as the registered agent shows up on Indiana's public business search, which anyone can pull up. Owners who would rather not have a home address indexed online usually go with a commercial service. If you travel or keep irregular hours, a service also solves the "available during business hours" requirement that you might otherwise fail on a bad week.

The Articles of Organization is the document that brings your LLC into legal existence in Indiana. You file it through INBiz, the Secretary of State's online portal. The state fee covers the filing — the INBiz fee calculator shows the current amount.

Online filings are fast, frequently cleared the same business day and seldom taking more than one. A mailed paper filing takes far longer. Once approved, the LLC shows up in Indiana's public database and your stamped documents become available.

What the Articles ask for

• LLC name — your full legal name with the required designator.
• Principal office address — home, office, or commercial mailbox; not a bare P.O. box.
• Registered agent name and Indiana street address — a genuine physical address, no P.O. boxes.
• Registered agent consent — the agent has to accept the appointment.
• Management structure — member-managed or manager-managed.
• Effective date — you may request a future effective date within the state's allowed window.

What you leave out

You do not name your members, spell out ownership percentages, describe your line of business, or reveal any financials. The Articles are a short formation document. All the internal detail lives in your operating agreement, which stays private.

The operating agreement is your LLC's internal rulebook. Indiana neither requires you to file it nor puts it in any public database — but you want it settled before you take on partners, sign contracts, or open a bank account.

What a solid agreement covers

• Ownership — each member's name and percentage interest.
• Capital contributions — what everyone put in at the start and what future contributions may be required.
• Profit and loss allocation — how gains and losses split among members; usually tracks ownership but does not have to.
• Distributions — when and how cash actually gets paid out.
• Management — who runs the day-to-day, their authority, and which decisions require a full member vote.
• Voting — whether votes are weighted by ownership or counted per member.
• Transfers — what happens when a member wants to sell or exit, including rights of first refusal.
• Dissolution — how the company gets wound down and assets distributed.

For a single-member LLC, the agreement backs up your claim that the LLC is a real separate entity — something a court weighs if anyone tries to reach past the liability shield. For a multi-member LLC it is essential: without it, Indiana's statutory defaults govern everything, and those defaults rarely mirror the deal the owners actually struck.

An Employer Identification Number is a nine-digit federal tax ID the IRS issues for free. Think of it as a Social Security number for the business — it goes on tax filings, bank applications, and payroll paperwork.

When you need one

• Your LLC has more than one member (multi-member LLCs file a partnership return and must have an EIN).
• You plan to hire employees.
• You want a business bank account — nearly every bank requires an EIN.
• You have elected S-corp or C-corp tax treatment.

A single-member LLC with no employees can technically use the owner's Social Security number for federal taxes, but most people get an EIN regardless. It keeps your SSN off business paperwork and makes opening an account cleaner.

How to apply

Complete the online application at the IRS EIN Assistant on IRS.gov. It takes about ten minutes and the number is issued on the spot — print the confirmation and use it that day. Online applications need a U.S. Social Security number or ITIN; applicants without one file Form SS-4 by fax or mail instead.

Keeping business and personal money apart is not optional if you want the liability protection to hold. Pay personal bills from the business account, or funnel business income through your personal checking, and you hand a court a reason to disregard the LLC entirely.

What banks usually want

• Your filed Articles of Organization from the Secretary of State
• Your IRS EIN confirmation letter
• Your operating agreement — many banks ask for it, so have it ready
• Photo ID for everyone who will sign on the account

Indiana community banks and credit unions are often more flexible with brand-new LLCs than the big national chains, and several online business banks now open accounts without a branch visit. Compare monthly fees, transaction caps, and minimum balances before committing.

Most of the work is front-loaded at formation. After that, Indiana asks relatively little — but the little it asks is easy to forget because of its timing.

The biennial Business Entity Report

Unlike most states, Indiana does not want a report every year. You file a Business Entity Report every two years through INBiz, due in your formation's anniversary month. It updates your registered agent, address, and management information — no financials. Miss it and, after a grace period, a late fee attaches; keep missing it and the state can administratively dissolve the LLC.

Registered agent upkeep and taxes

Your registered agent must stay reachable at an Indiana address throughout. If yours changes, file the update through INBiz. Separately, if you sell taxable goods or services you will register for sales tax with the Indiana Department of Revenue, and your pass-through profit is subject to Indiana's state and county income taxes on your personal return.

A simple compliance rhythm

Set a reminder for your report's anniversary month two years out, keep your registered agent information accurate, and keep business and personal finances strictly separate. Do those three things and an Indiana LLC is genuinely low-maintenance to run.
