What an Indiana LLC has to file, what it pays, and where to look it up. An LLC is a state entity, so the filing requirements on this page are specific to Indiana.

LLC rules, taxes and details in Indiana

Formation

You form an Indiana LLC by filing Articles of Organization with the Indiana Secretary of State Business Services Division. The standard domestic filing cost is $95 online or $100 on paper. An LLC formed in another state that needs authority to do business in Indiana generally files a foreign registration and pays $105 online or $125 on paper.

The formation filing normally identifies:

• The LLC’s legal name
• The principal office or mailing address requested by the state
• The registered agent and registered office
• The organizer or authorized person submitting the filing
• Any management, duration or professional-service details required by the form

The filing creates the state entity. It does not automatically complete federal tax registration, state tax accounts, payroll registration, local licenses or foreign qualification in another state.

Naming rules

• The name must contain Limited Liability Company, LLC, L.L.C. or another abbreviation accepted by Indiana.
• It must be distinguishable from names already held on the state register.
• Words connected with banking, insurance, trusts, universities or licensed professions can require approval from another regulator.

Search the public register before filing, but remember that state name availability is not the same as trade mark clearance or ownership of a matching web domain.

Registered agent

Every Indiana LLC must keep a registered agent and registered office on the state record. The agent accepts lawsuits and official notices for the company. The address must normally be a physical address in Indiana, not only a PO Box, and the agent must be available during ordinary business hours.

An owner can sometimes act as agent, but using an owner’s home address makes that address part of the public record. A change of agent or office should be filed promptly rather than waiting for the next recurring report.

Annual or recurring filing

• Requirement: Business Entity Report every two years, $32 online or $50 on paper.
• Deadline: During the anniversary month every second year.
• What it updates: The filing normally confirms the LLC’s address, registered agent and management information.
• If it is missed: Late fees, loss of good standing and administrative dissolution or cancellation can follow.

Key fee schedule

Articles of Organization, domestic LLC	$95 online or $100 on paper
Foreign LLC registration	$105 online or $125 on paper
Recurring state filing	Business Entity Report every two years, $32 online or $50 on paper

Expedited processing, certified copies, name reservations, amendments, reinstatement and local licenses can add to these amounts. Use the official filing portal for the price that applies on the day you submit.

Two details people get wrong

First: The report is biennial and follows the anniversary month, so a generic year-end reminder is unreliable.

Second: County income tax can affect owners and employees even though the state income tax is flat.

LLC tax information in Indiana

An LLC is created by state law, but its federal tax classification depends on the number of members and any election it makes. State filing status and federal tax status are related, but they are not the same thing.

Federal classification

• A single-member LLC is disregarded by default. Its business activity normally appears on the owner’s federal return.
• A multi-member LLC is a partnership by default. It files Form 1065 and gives each member a Schedule K-1.
• An eligible LLC can elect C corporation treatment on Form 8832 or S corporation treatment on Form 2553.
• Payroll tax, information return and estimated payment deadlines can apply regardless of the default classification.

Indiana state taxes

• Owner income tax: Indiana applies a flat individual adjusted gross income tax, with county income taxes added.
• Entity-level tax: An LLC taxed as a C corporation is subject to Indiana corporate adjusted gross income tax.
• Sales or receipts tax: The state sales tax rate is 7%.
• Employer accounts: An LLC with employees normally needs state withholding and unemployment insurance registration in addition to its federal EIN.

Tax treatment turns on the LLC’s federal election, its owners, where it operates, what it sells and whether it has employees. Register through the Indiana tax authority for the accounts that apply. A Secretary of State filing does not create those accounts automatically.

LLC lookup in Indiana

Indiana business records are available through the state’s public entity search. The record normally shows the legal name, entity number, formation or registration date, status, registered agent and filing history.

Search the register

Use the official Indiana business entity search.

• Search by name to check availability or find the legal entity behind a trading name.
• Search by entity number when you already have the state file number.
• Review status and filing history before relying on a supplier, customer or acquisition target.

Good standing means the entity has met the state’s basic maintenance requirements. It does not prove that every tax return, license or private contract is current.

File and register

• Indiana Secretary of State Business Services Division: Form the LLC, register a foreign LLC, update the registered agent, file the recurring report and request certificates.
• Indiana tax authority: Register for income, sales or receipts tax, withholding and other accounts that apply.
• IRS: Apply for an EIN and make any federal classification election.
• Local government: Check city and county business licenses, zoning, professional permits and local taxes.
