Quick Answer: Forming an LLC in Indiana
The Indiana Secretary of State Business Services Division handles all entity filings. Most steps are completable online through the INBiz portal (inbiz.in.gov).
The five essential steps:
- File Articles of Organization (Form 49457) with the Indiana Secretary of State Business Services Division.
- Appoint a registered agent with a physical street address in Indiana.
- Draft an operating agreement (kept internally, never filed with the state).
- Obtain an Employer Identification Number (EIN) from the IRS using Form SS-4.
- Meet ongoing obligations, including the annual report (Form 49458) and applicable state taxes.
The legal framework for Indiana LLCs is Indiana Code Title 23, Article 18, known as the Indiana Business Flexibility Act.
Key Steps to Form Your Indiana LLC
Step 1: Search for Name Availability
Confirm your preferred name is available before filing. Use the Indiana Secretary of State Business Services Division's free name search tool at inbiz.in.gov. If another active entity holds your exact name or a name too similar to pass the distinguishability test, you will need an alternative.
Step 2: Reserve the Name (Optional)
Name reservation is not required, but it locks your chosen name for 120 days while you prepare your filing. The Indiana Secretary of State Business Services Division accepts reservation requests online or by mail. Consult the Indiana Secretary of State Business Services Division fee schedule for the current reservation fee.
Step 3: Appoint a Registered Agent
Designate a registered agent before filing. The agent must have a physical Indiana street address and be available during normal business hours. See the full requirements in the Registered Agent section below.
Step 4: File Articles of Organization (Form 49457)
This document legally creates your LLC. File online through INBiz or by mail to the Indiana Secretary of State Business Services Division. Required information includes:
- LLC name (with required designator)
- Registered agent name and street address
- Principal office address
- Name and address of each organizer
- Whether the LLC is member-managed or manager-managed
Step 5: Understand Filing Fees and Processing Times
Consult the Indiana Secretary of State Business Services Division fee schedule at inbiz.in.gov for current filing fees and processing times, including expedited options.
Step 6: Obtain an EIN
Apply at irs.gov/ein. The online process is free and takes minutes. An EIN is required to open a business bank account, hire employees, and file most tax returns.
Step 7: Draft an Operating Agreement
Indiana does not require filing an operating agreement, but one is essential for governing the LLC's internal operations. See the Operating Agreement section below for details.
Naming Your Indiana Limited Liability Company
Indiana's naming rules are set out in Indiana Code § 23-18-2-4. Correct adherence prevents filing delays.
Required Designators
Your LLC name must include one of the following:
- "Limited Liability Company"
- "LLC"
- "L.L.C."
- "Limited Liability Co."
- "Ltd. Liability Company"
- "Ltd. Liability Co."
Prohibited and Restricted Words
Indiana Code § 23-18-2-4 bars names that:
- Imply the LLC is a government agency (e.g., "FBI," "Treasury," "State Department").
- Suggest a purpose the LLC is not licensed to carry out (e.g., using "Bank" or "Insurance" without appropriate regulatory approval).
- Are identical or not distinguishable from an existing registered entity name in Indiana.
Distinguishability Requirement
Under Indiana Code § 23-18-2-4, names must be distinguishable from existing entities. The Indiana Secretary of State Business Services Division determines distinguishability; minor variations may not suffice. Use the entity search tool at inbiz.in.gov or contact the Business Services Division for clarification.
How to Search and Reserve
- Go to inbiz.in.gov and use the entity search tool.
- Search your proposed name and close variations.
- If available, file a name reservation through the same portal to hold it for 120 days.
Indiana Registered Agent Requirements
Indiana Code § 23-18-2-10 requires every Indiana LLC to maintain a registered agent and a registered office in the state at all times.
What a Registered Agent Does
The registered agent receives legal process, government notices, and tax documents. Failure to receive service can result in a default judgment.
Legal Requirements
Under Indiana Code § 23-18-2-10, the registered agent must:
- Maintain a physical street address in Indiana (P.O. boxes do not qualify as the registered office).
- Be available during normal business hours to accept service of process.
Who Can Serve
- An individual Indiana resident (including a member or manager of the LLC).
- A domestic corporation authorized to act as a registered agent.
- A foreign corporation authorized to do business in Indiana.
Many small LLCs use a member as the registered agent. Larger or multi-state operations often hire a commercial registered agent service to ensure reliability and to keep a member's home address off public records.
Consequences of Non-Compliance
Failing to maintain a registered agent puts your LLC at risk of administrative dissolution by the Indiana Secretary of State Business Services Division. It also creates exposure if legal notices go undelivered.
Changing Your Registered Agent
File a Statement of Change of Registered Agent or Registered Office with the Indiana Secretary of State Business Services Division through INBiz. Consult the Business Services Division fee schedule for the current change fee.
Operating Agreement & EIN for Indiana LLCs
Operating Agreement
Indiana Code § 23-18-4-5 authorizes members to adopt an operating agreement to govern the LLC's internal affairs. While not filed with the state, a written operating agreement is crucial.
A well-drafted operating agreement covers:
- Management structure (member-managed vs. manager-managed).
- Voting rights and decision-making thresholds.
- Capital contributions and ownership percentages.
- Profit and loss distribution.
- Procedures for adding or removing members.
- Buy-sell provisions if a member wants to exit.
- Dissolution procedures.
Without an operating agreement, Indiana's default statutory rules (Indiana Code Title 23, Article 18) govern, which may not align with members' intentions. The agreement also serves as a primary reference for dispute resolution.
Single-member LLCs also benefit, as an operating agreement reinforces the separation between the owner and the entity, supporting liability protection.
EIN (Employer Identification Number)
An EIN is a federal tax identification number issued by the IRS at no cost. Apply using IRS Form SS-4, available at irs.gov. Online applications generate an EIN immediately. Consult IRS Form SS-4 instructions for processing estimates for fax and mail applications.
You need an EIN if your LLC:
- Has more than one member.
- Has or plans to hire employees.
- Elects to be taxed as a corporation.
Single-member LLCs without employees can use the owner's Social Security Number for federal tax purposes, but most banks require an EIN for business checking accounts. Obtaining one is free and quick.
Federal Tax Classification
By default, the IRS treats a single-member LLC as a disregarded entity and a multi-member LLC as a partnership. Either type can elect C-corporation status by filing IRS Form 8832, or S-corporation status by filing IRS Form 2553 (subject to eligibility). Indiana generally follows federal classification for state income tax; consult the Indiana Department of Revenue (dor.in.gov) or a CPA for specific guidance.
Ongoing Compliance for Indiana LLCs
Maintaining good standing requires ongoing compliance.
Annual Report
Indiana Code § 23-18-12-1 requires Indiana LLCs to file an annual report (Form 49458) with the Indiana Secretary of State Business Services Division. The report is due by the end of the anniversary month of the LLC's formation each year. For example, if you formed your LLC in March, your annual report is due by March 31 each subsequent year.
Consult the Indiana Secretary of State Business Services Division fee schedule at inbiz.in.gov for the current annual report filing fee. Late or missed filings can result in administrative dissolution.
State Tax Obligations
Contact the Indiana Department of Revenue (dor.in.gov) to determine which of the following apply to your LLC:
- Sales tax: Required if you sell taxable goods or certain services in Indiana. Register through INBiz.
- Withholding tax: Required if you have Indiana employees.
- Corporate adjusted gross income tax: Applies if your LLC has elected corporate tax status or is otherwise treated as a corporation for Indiana tax purposes.
- Pass-through entity tax: Indiana has enacted pass-through entity tax provisions; consult the Indiana Department of Revenue for current rules.
Federal Tax Obligations
Federal filing requirements depend on your entity classification:
- Disregarded entity: Report income on the owner's Form 1040 (Schedule C or E).
- Partnership: File Form 1065 and issue Schedule K-1 to each member.
- C-corporation: File Form 1120.
- S-corporation: File Form 1120-S and issue Schedule K-1 to each member.
Local Licenses and Permits
Indiana does not have a statewide general business license, but your city or county may require one. Check with your local city clerk or county government. Certain industries (contractors, food service, healthcare, childcare) require state-level professional or occupational licenses regardless of business structure. Consult the relevant Indiana state agency for your industry.
Record-Keeping
Maintain accurate records of member meetings (if any), financial statements, tax filings, and any amendments to your operating agreement or Articles of Organization. Accurate records are essential for maintaining the LLC's liability protection.

Federal Tax Considerations
The federal tax treatment for LLCs varies based on the number of members. A single-member LLC is treated as a disregarded entity under IRC § 7701, reporting income on Schedule C, while a multi-member LLC is classified as a partnership, filing Form 1065 and issuing K-1s to members. An LLC can elect to be taxed as an S-corporation by filing Form 2553, which may alter self-employment tax obligations.
- Single-member LLCs report income on Schedule C (IRC § 61).
- Multi-member LLCs file Form 1065 and provide K-1s to members (IRC § 703).
- An S-corp election via Form 2553 can reduce self-employment tax exposure (IRC § 1362).
- Self-employment tax is 15.3% on active LLC income up to the Social Security wage base (IRC § 1401).
- The Qualified Business Income deduction under IRC § 199A allows for up to a 20% deduction of qualified pass-through income, subject to specific thresholds and rules for specified service trades or businesses (SSTB).
- Most states conform to federal § 179 limits, but Indiana may decouple — verify with a state CPA.
This is not tax advice — consult a CPA familiar with LLC formation for your specific situation.
