Step 1: Choose Your Indiana Business Structure

Before you register anything, decide how the business will be legally organized, because the structure drives your paperwork, taxes, and liability. In Indiana the common choices are a sole proprietorship, a general partnership, a limited liability company (LLC), and a corporation. A sole proprietorship needs no state formation filing, but it gives you no liability shield.

Most new Indiana small businesses choose the LLC because it separates personal assets from business debts while keeping pass-through taxation. If you want the liability protection of a separate legal entity, you form an LLC or corporation with the Indiana Secretary of State. Compare the trade-offs on our S-corp vs LLC and how to form an LLC pages before you file, and review key terms in the glossary.

Step 2: Register the Entity With the Indiana Secretary of State

If you form an LLC, you create it by filing the Articles of Organization with the Indiana Secretary of State, generally through the state's INBiz online system. The state filing fee is $95 online. The filing lists the company name, its registered agent and office, and the management structure.

Your name must be distinguishable from existing entities on the state register; run a Indiana business entity search first. A corporation instead files articles of incorporation. Adopt an operating agreement for an LLC (or bylaws for a corporation) - Indiana does not file it, but it governs ownership, voting, and profit splits. See our Indiana formation document guide for the exact contents.

Step 3: Appoint a Indiana Registered Agent

Every Indiana LLC and corporation must continuously maintain a registered agent with a physical street address in Indiana - a P.O. box alone will not satisfy the registered-office requirement. The agent receives service of process, tax notices, and official state mail on the company's behalf.

You may act as your own agent if you live in Indiana and keep regular business hours, appoint a manager, or hire a commercial registered agent service. The agent must consent to the role. If you later change agents, you file a change-of-agent form with the Indiana Secretary of State. Failing to maintain an agent can lead to administrative dissolution, so keep the designation current.

Step 4: Get an EIN and Register for Taxes

Apply for a federal Employer Identification Number (EIN) from the IRS - it is free and takes minutes online. You need an EIN to open a business bank account, hire employees, and file most tax returns; a multi-member LLC or any entity with employees is required to have one.

By default the IRS treats a single-member LLC as a disregarded entity and a multi-member LLC as a partnership, and either may elect S-corporation treatment on Form 2553. For Indiana taxes, register with the Indiana Department of Revenue: Indiana taxes pass-through business income on the owners' individual returns at a flat state rate, and the DOR administers sales and withholding tax. If you sell taxable goods or services, obtain a Registered Retail Merchant Certificate ($25). Learn more on our business tax page.

Step 5: Get Indiana Business Licenses and Permits

Indiana regulates many activities through licenses and permits rather than a single universal license. Check for a general Indiana business license requirement, then layer on local city or county licenses for your physical location, plus professional or occupational licenses for regulated trades such as contractors, cosmetologists, health services, and food handling.

The federal SBA licensing guide and our business license overview explain the layers. If you operate under a name different from the legal entity name, file a Indiana DBA (fictitious name). Confirm zoning and home-occupation rules with your municipality before you open.

Step 6: Meet Ongoing Indiana Requirements

Registration is not one-and-done. Indiana LLCs must file a Business Entity Report every two years ($31 online, $50 by mail) with the Secretary of State to stay in good standing. Keep your registered agent current, renew local licenses, and file your federal and state tax returns each year. Missing an annual filing is the most common way small businesses fall out of good standing and risk administrative dissolution.

Maintain a separate business bank account and clean books so your liability shield holds up. If ownership, address, or management changes, update the record with the Indiana Secretary of State. When you are ready to wind down, follow our how to dissolve an LLC in Indiana guide rather than simply abandoning the entity.

Verify Current Details and Avoid Common Pitfalls in Indiana

State fees, tax rates, forms, and deadlines change from year to year, so before you file or pay anything, confirm the current figures directly on the official Indiana agency websites cited below. The amounts on this page are effective for 2026 and are set by the government, not by any filing service. Public records and most state forms are free or low-cost, and a federal EIN is always free from the IRS - be cautious of third-party websites that charge inflated fees to file routine state paperwork or to obtain a number the government issues at no cost. Reading the primary source yourself is the surest way to avoid outdated or misleading second-hand information, which is exactly why every figure here links to a Indiana agency, statute, or the IRS.

A second common pitfall is blurring the line between you and your business. If you operate through an LLC or corporation, the liability protection depends on treating the entity as genuinely separate: keep a dedicated business bank account, sign contracts in the company name, keep clean records, and adopt an operating agreement even if Indiana does not require you to file one. Commingling personal and business money is the fastest way to weaken the shield if the company is ever sued. Owners should also plan for taxes early - set aside money for income and self-employment tax, and review whether an S-corp election fits once profits grow. See our business tax overview for how the pieces connect.

Finally, do not confuse a state business registration with trademark ownership. Clearing a name in the Indiana business entity search means no other registered entity has that exact name - it does not grant nationwide rights or clear a federal trademark, so search the USPTO database before you invest in branding. Likewise, if you use a name different from your legal entity name, file a Indiana DBA. When your business changes or winds down, follow the proper Indiana dissolution steps rather than simply abandoning the entity, which leaves fees and filings running.
