What Is an LLC in Indiana?
A limited liability company is a business entity formed under the Indiana Business Flexibility Act (Ind. Code § 23-18-1-1 et seq.) that provides its owners — called members — with limited liability protection while offering flexible management and pass-through federal tax treatment. Indiana’s LLC law is supplemented by the Uniform Business Organizations Administrative Provisions Act (Ind. Code § 23-0.5), which governs naming, registered agents, filing procedures, and fees for all entity types in the state.
Members are generally not personally liable for the LLC’s debts and obligations; their risk is limited to their investment in the company. Under Ind. Code § 23-18-4-1, management of the LLC’s business and affairs is vested in its members unless the articles of organization provide for one or more managers. By default, a single-member LLC is taxed as a disregarded entity, and a multi-member LLC is taxed as a partnership for federal income tax purposes, though an LLC may elect corporate taxation by filing IRS Form 8832. Indiana does not impose a franchise tax on LLCs, and the state’s flat individual adjusted gross income tax rate applies to pass-through income at the member level. The members may govern the LLC’s internal affairs through an operating agreement, which may modify many of the default statutory rules.
Indiana LLC Name Search
The LLC’s name must be distinguishable on the records of the Secretary of State from every other entity name on file. Under Ind. Code § 23-0.5-3-1, a name that is not distinguishable from an existing entity name, will be rejected unless the existing entity consents in writing. The name must also contain the phrase “Limited Liability Company” or the abbreviation “L.L.C.” or “LLC,” as required by Ind. Code § 23-0.5-3-2. Abbreviations such as “Ltd.” or “Co.” do not satisfy this designator requirement.
Indiana does not maintain a statutory list of categorically prohibited words within its naming chapter. However, the use of terms such as “bank” or “insurance” may be restricted by separate regulatory frameworks, and a name may not falsely imply that the entity is a government agency. The official INBiz Business Search allows an organizer to check whether a proposed name is available before filing, though passing the online search does not guarantee acceptance—final determination occurs when the Secretary of State reviews the articles of organization.
Name Reservation: An organizer may reserve the exclusive right to a name for 120 days by filing an electronic application through INBiz and paying a $10 fee, as set by Ind. Code § 23-0.5-9-7. Reservations are renewable for successive 120-day periods at $10 each, and a cancellation of a reserved name carries a $1 filing fee.
Choosing an LLC Registered Agent in Indiana
Every LLC formed in Indiana must designate a registered agent and maintain a registered office address in the state. The agent receives service of process, legal notices, and official government correspondence on behalf of the LLC, and the registered office is the physical address where the agent is available during normal business hours.
Under Ind. Code § 23-0.5-4-3, a registered agent must be an individual, a general partnership, a domestic filing entity, or a registered foreign entity. An individual agent must be an Indiana resident whose business office is the same as the registered office. The registered office address must be a physical Indiana street address, not a P.O. Box, where service of process can be personally delivered. A business entity cannot serve as its own registered agent.
The designated registered agent must consent to the appointment before being named in the articles of organization. Indiana’s official Articles of Organization (State Form 49459) includes a registered agent consent statement as part of the form, confirming that the agent has agreed to serve. The Secretary of State also publishes a standalone Consent for Use of Entity Name (State Form 56370) for separate name-consent matters.
Note: Failure to maintain a registered agent can result in administrative dissolution of the LLC, and the entity may lose the exclusive right to its business name within 120 days of dissolution.
LLC Filing Requirements in Indiana
An LLC is formed in Indiana by delivering articles of organization to the Secretary of State for filing, as authorized by Ind. Code § 23-18-2-4. At least one person may form an LLC; the organizer does not need to be a member at the time of formation or afterward.
The formation document is filed using Articles of Organization — State Form 49459. The articles must contain the following:
- The LLC’s name, including a required designator
- The street address of the LLC’s registered office in Indiana and the name of the registered agent at that office
- The latest date upon which the LLC is to dissolve, or a statement that its duration is perpetual
- If the LLC will be managed by one or more managers, a statement to that effect
- Any other provisions not inconsistent with Indiana law that the members wish to include
The articles must be signed by at least one organizer, who verifies the statements under penalties of perjury.
Filing methods and fees are summarized below. The statutory base fees are set by Ind. Code § 23-0.5-9-19, and online filings carry an additional Enhanced Access surcharge authorized under Ind. Code § 4-5-10-2.
- Online: File through the NBiz portal. The total fee is $95 ($75 statutory fee + $20 Enhanced Access surcharge). A processing fee of up to 2.15% is added for credit card payments. Online filings are typically processed within approximately one business day.
- By Mail: Send the completed form and a check or money order for $100 to Business Services Division, 302 W. Washington Street, Room E018, Indianapolis, IN 46204.
- In Person: Walk-in service is available at the same address during business hours (Monday–Friday, 8:00 a.m.–4:30 p.m.). Priority service is available by appointment through the Secretary of State’s online Appointment Scheduler.
Under Ind. Code § 23-0.5-2-3, the filing is effective on the date and time recorded by the Secretary of State, unless the organizer specifies a delayed effective date up to 90 days after filing. Upon acceptance, the Secretary of State returns a certificate confirming that the LLC has been legally formed.
Note: Indiana requires every LLC to file a Business Entity Report every two years, not annually, beginning two years after formation. The report is due during the LLC’s anniversary month and costs $32 online or $50 by paper, as detailed on the INBiz Business Entity Reports page.

LLC Operating Agreement in Indiana
Indiana law does not require an LLC to adopt an operating agreement, but Ind. Code § 23-18-4-5 expressly authorizes members to “enter into an operating agreement to regulate or establish any aspect of the affairs of the limited liability company or the relations of its members.” The operating agreement is not filed with the state—it is an internal governance document retained by the LLC and its members.
An operating agreement establishes the management structure, defines the authority of managers or managing members, governs the allocation of profits and losses, sets the terms for admitting new members or transferring membership interests, and defines procedures for dissolution and winding up. A written operating agreement may also modify, increase, decrease, limit, or eliminate fiduciary duties owed between members and managers, as permitted by Ind. Code § 23-18-4-4.
Without an operating agreement, Indiana’s statutory defaults control. Under Ind. Code § 23-18-4-1: The LLC is member-managed unless the articles of organization specify manager management. Profits and losses are shared in proportion to each member’s contributions, and transferability of interests is restricted under the act. Even a single-member LLC benefits from a written operating agreement, because it reinforces the separation between the member’s personal assets and the LLC’s assets—a factor courts may consider when evaluating whether limited liability protection should be upheld.
How to Get an EIN for an LLC in Indiana
A federal Employer Identification Number is a nine-digit number issued by the Internal Revenue Service that identifies the LLC for federal tax purposes. Any LLC that has employees, files certain federal tax returns (such as excise or employment tax returns), or withholds taxes on income paid to a nonresident alien must have an EIN. A single-member LLC with no employees is not strictly required to obtain an EIN, but one is typically needed to open a business bank account, and obtaining one is generally recommended.
The fastest method is the IRS EIN Online Application, which issues the EIN immediately upon completion. The online tool is available Monday through Friday, 7:00 a.m. to 10:00 p.m. Eastern Time, and the applicant must have a valid Taxpayer Identification Number (SSN or ITIN). The LLC must be located in the United States or a U.S. territory.
Alternatively, an applicant may complete IRS Form SS-4 and submit it by fax (approximately four business days for processing) or by mail (approximately four to five weeks). The application requires the name and Taxpayer Identification Number of the LLC’s responsible party, the individual who controls, manages, or directs the LLC, and the disposition of its funds and assets. For a single-member LLC, this is typically the sole member. There is no fee to apply for an EIN.
Registering for State Taxes in Indiana
Indiana treats LLCs as pass-through entities for state income tax purposes, meaning the LLC itself does not pay a separate entity-level income tax. Each member reports their distributive share of the LLC’s income on their individual Indiana adjusted gross income tax return at the state’s flat rate of 2.95% (for 2026), plus any applicable county income tax. Indiana does allow an elective pass-through entity tax under Ind. Code § 6-3-2-1.7 that enables the entity to pay tax at the entity level to help owners avoid the federal $10,000 SALT deduction cap, though this election is optional.
If the LLC sells tangible personal property or certain services at retail, it must register for a Registered Retail Merchant Certificate through INBiz Tax Registration or the Indiana Department of Revenue. Indiana’s sales tax rate is 7%, and a registration fee of $25 per business location applies. Upon registration, the LLC receives its certificate and may begin collecting and remitting sales tax.
Employers must also register for state and county income tax withholding through INBiz. After registration, the Indiana Department of Revenue issues a 10-digit Taxpayer Identification Number used for filing Form WH-1 (Withholding Tax Voucher) and the annual WH-3 reconciliation via the INTIME portal.
| Tax Type | Agency | Registration Method | Fee |
| State/county income tax withholding | Indiana Department of Revenue | INBiz Tax Registration | None |
| Sales and use tax (RRMC) | Indiana Department of Revenue | INBiz Tax Registration | $25 per location |
| Pass-through entity tax (elective) | Indiana Department of Revenue | PTET election via DOR | None |
Registering as an Employer in Indiana
An LLC that hires employees in Indiana must register with the appropriate state agencies for unemployment insurance, income tax withholding, and workers’ compensation coverage.
Unemployment Insurance: Indiana’s unemployment insurance program is administered by the Indiana Department of Workforce Development (DWD). Employers who pay wages in Indiana and meet employer qualifications must register through the Employer Self-Service (ESS) portal on Uplink. DWD will assign a State Unemployment Tax Act (SUTA) account number upon registration.
State Income Tax Withholding: Employers must withhold state and county income taxes from employee wages. Registration for withholding is completed through INBiz, and returns are filed and paid through the INTIME portal. An EIN from the IRS is required before registering with the state.
Workers’ Compensation Insurance: All Indiana employers must provide workers’ compensation coverage to their employees, as required by Ind. Code § 22-3-2-2. Indiana uses private insurance carriers for workers’ compensation; employers must obtain a policy from a licensed carrier and file proof of insurance with the Indiana Workers’ Compensation Board.
New Hire Reporting: Federal and state law requires employers to report newly hired and rehired employees within 20 days of the hire date. Reports must be submitted electronically to the Indiana New Hire Reporting Center. Failure to report can result in a fine of $25 per unreported employee, or up to $500 if the failure involves a conspiracy between employer and employee.
| Obligation | Agency | Registration Method |
| Unemployment insurance | Indiana DWD | Uplink Employer Self-Service |
| State/county income tax withholding | Indiana DOR | INBiz Tax Registration |
| Workers’ compensation insurance | Indiana Workers’ Compensation Board | Private carrier; proof filed with WCB |
| New hire reporting | Indiana New Hire Reporting Center | in-newhire.com |
The LLC must also comply with federal employer obligations, including filing IRS Form 941 (quarterly payroll tax return), paying FUTA (Federal Unemployment Tax Act) taxes, and completing Form I-9 (Employment Eligibility Verification) for each new hire.
