How to Form an LLC in Indiana — 2026 Filing Guide

Required?

Yes

Who can serve

Indiana resident individual with a physical IN street address, or a business entity authorized to act as registered agent in Indiana (no PO boxes); must be available during normal business hours under IC § 23-18-2-3

Can I serve myself?

Yes

Commercial RA cost

~$100/yr

Serving as your own RA places your Indiana street address on the public INBiz record. Commercial RA services ($50–$150/yr) keep your personal address private and ensure legal mail and service of process are never missed.

1. Search name availability with the Indiana Secretary of State Search the Indiana SOS name database via INBiz at inbiz.in.gov to confirm your desired LLC name is available. The name must include a valid designator under IC § 23-18-2-2 and must not be deceptively similar to an existing IN entity. Optional: reserve for 120 days ($20) while preparing documents.
2. Appoint an Indiana registered agent Designate a registered agent with a physical Indiana street address (no PO boxes), available during normal business hours to accept service of process under IC § 23-18-2-3. Indiana residents may self-serve as RA. Out-of-state owners use a commercial RA service ($50–$150/yr).
3. File the Articles of Organization ($95) File online via the INBiz portal at inbiz.in.gov. The Articles require the LLC name, registered agent name and IN street address, and organizer information. Pay the $95 filing fee. Standard online processing through INBiz is typically 3–5 business days; expedited processing is available for an additional fee.
4. Draft an Operating Agreement Indiana's LLC Act (IC § 23-18-4-5) strongly recommends an Operating Agreement to govern member rights, distribution rules, management authority, voting procedures, and dissolution. The OA is not filed with the state but is essential for multi-member LLCs and for reinforcing the liability shield in single-member LLCs. Banks will request the OA for account opening.
5. Obtain an EIN from the IRS Apply for an EIN at irs.gov/ein -- free and immediate.
6. Register for Indiana taxes (if applicable) LLCs selling tangible personal property or certain services in Indiana must register with the Indiana Department of Revenue via the INTime portal at intime.dor.in.gov for a Registered Retail Merchant Certificate. Indiana's state sales tax rate is 7% (flat, with no local surtaxes on top of the state rate, though county income taxes apply to individual members). LLC members' pass-through income is subject to Indiana's 3.05% flat individual income tax.
7. File the Biennial Business Entity Report every 2 years Indiana LLCs must file a Business Entity Report every two years — not annually — in the LLC's anniversary month. Online filing via INBiz costs $31 (paper filing: $50). Budget a calendar reminder for every other anniversary month. Failure to file results in administrative dissolution. The biennial cadence means the amortized annual cost is $15.50/yr — one of the lowest report-related costs among Midwest states.

Formation context

Who should form in Indiana?

Recommended for

Indianapolis-area businesses (logistics, manufacturing, distribution, healthcare) that benefit from Indiana's central Midwest location and low compliance overhead; Logistics and 3PL operators who value Indiana's interstate highway network (I-65, I-70, I-74, I-69) and FedEx ground hub infrastructure; Small business owners who want a low flat income tax (3.05%) and biennial report schedule

Tax treatment (default)

Pass-through by default: single-member LLCs are disregarded entities (Schedule C); multi-member LLCs are partnerships (Form 1065). Indiana's 3.05% flat personal income tax applies to Indiana-resident members' allocated LLC income. No franchise tax. No entity-level LLC income tax.

Indiana is most cost-effective for businesses that actually operate in Indiana. Foreign-qualifying a non-Indiana LLC in Indiana triggers similar filing and biennial report fees. If you have no Indiana presence, form in the state where you actually operate, or use Wyoming/Delaware for holding structures.

No publication requirement in Indiana — unlike New York or Nebraska, you do not need to publish notice in a newspaper after filing.

FAQ

Common Indiana LLC formation questions

Still deciding between an LLC, sole proprietorship, S-Corp, or C-Corp? Our entity-type comparison breaks down formation cost, tax treatment, liability shield, and compliance complexity for all four structures side by side.

Once your LLC clears ~$80K in annual net profit, an S-Corp election (IRS Form 2553) typically saves $5,000–$15,000/year in self-employment taxes by splitting owner income into a W-2 salary + tax-free distributions. The election is free — Form 2553 has no IRS filing fee. The key decision factors: your net income level, a defensible reasonable-compensation salary, and the 75-day Form 2553 filing window after LLC formation.

Already operating as a sole proprietor, or wondering whether a cheap county DBA filing ($10–$100) is enough instead of forming an LLC? A DBA lets you operate under a trade name — but provides zero liability protection. Our DBA vs LLC comparison breaks down exactly when a DBA is sufficient and when you need a state LLC filing.

Missing your annual report deadline triggers late fees and — if left long enough — administrative dissolution, which voids your LLC's liability shield until reinstated. Know your Indiana deadline, fee, and the consequences of missing it.

Also see the LLC annual report requirements hub for state-by-state deadlines, fees, late penalties, and reinstatement rules.

If your LLC opens an office, hires employees, or regularly does business in another state, you must foreign-qualify there — or face fines, back taxes, and loss of standing to sue. Our foreign qualification guide covers when you need it, how to file a Certificate of Authority, and what it costs.

Your Articles of Organization are filed — now make your LLC operational. Four actions every new LLC owner needs to take:

Formation gets your LLC into existence; contracts, trademark protection, operating agreement review, and vendor-document review keep it usable. Compare subscription and per-document legal platforms before you rely on a template or pay a local attorney retainer.

Commingling personal and business funds is the #1 way LLC owners lose their liability shield. A separate business account — in your LLC's legal name, with your EIN — is the foundational act of corporate formality. Mercury, Novo, Bluevine, Relay, and Found open same-day with no monthly fees. Compare online banks vs. Chase and Bank of America.

How you pay yourself depends on your LLC's tax classification — not what you call the transfer. A disregarded single-member LLC pays via owner draw with SE tax on all net profit. An S-Corp-elected LLC splits income between a W-2 salary (FICA applies) and tax-free distributions. Getting this wrong triggers IRS audit risk and SE-tax errors.

Single-member LLCs file Schedule C with their personal Form 1040 (due April 15). Multi-member LLCs file Form 1065 by March 15. S-Corp-elected LLCs file Form 1120-S by March 15. Know your form, your deadline, and the common deductions — home office, vehicle, retirement contributions, and startup costs — before your first April filing.
