Indiana is one of the most business-friendly states in the Midwest, with low formation costs, a flat income tax rate of just 2.95%, and a streamlined one-stop registration portal called INBiz. You can form an LLC online for $95 and have it processed in one business day. The state’s biennial report is only $32 every two years – far cheaper than neighbors like Illinois ($75/year) or Ohio ($99 biennial).
That said, Indiana has a 7% sales tax rate (the highest flat rate in the Midwest), all 92 counties levy their own income tax on top of the state rate (adding 0.5% to 3.38%), and workers’ compensation is required as soon as you hire your first employee. There is no single statewide business license – licensing happens at the industry and local level. This guide walks you through every step using official Indiana government sources.
How to Start a Business in Indiana (Step by Step)
Step 1: Choose Your Business Structure
Your business structure determines your personal liability, tax treatment, and ongoing paperwork. The most common options in Indiana:
- Sole Proprietorship – Simplest to start, no state filing required (just a DBA filing with your county recorder if using a trade name). You are personally liable for all business debts.
- LLC (Limited Liability Company) – Most popular choice for small businesses. Protects personal assets, offers flexible tax treatment, and is affordable to form in Indiana ($95 online).
- Corporation (S-Corp or C-Corp) – More formal structure with shareholders, directors, and officers. Better for businesses seeking investors. Indiana’s corporate income tax rate is 4.9%.
- Partnership – For businesses with two or more owners. Options include general partnership (GP), limited partnership (LP), or limited liability partnership (LLP).
For most small businesses, an LLC is the right choice. Indiana’s $95 online filing fee and $32 biennial report make it one of the most affordable states in the country for LLC maintenance.
Step 2: Register Your Business with the State
LLC Formation via INBiz
Indiana business entities are registered through the Secretary of State, Business Services Division. All filings go through the INBiz portal – Indiana’s one-stop shop for business registration, tax registration, and professional licensing.
| Item | Cost |
|---|---|
| Articles of Organization (online via INBiz) | $95 + processing fee (~$97 total) |
| Articles of Organization (mail/in-person) | $100 |
| Business name reservation (optional) | $10 (120 days) |
| Biennial Business Entity Report | $32 (online) / $50 (mail) every 2 years |
| Assumed Business Name / DBA (via SOS) | $20 (online) / $30 (mail) |
| DBA for sole proprietors (County Recorder) | ~$25-$35 (varies by county) |
How to file:
- Go to INBiz and create an account
- File Articles of Organization online – choose a business name that includes “LLC,” “L.L.C.,” or “Limited Liability Company”
- Check name availability through the Business Entity Search
- Designate a registered agent with a physical Indiana address – must be at least 18 years old, reside in Indiana, and be available during normal business hours
- Pay the $95 filing fee online (credit card, plus ~2.15% processing fee)
- Online filings are typically processed within 1 business day
Biennial Business Entity Report
Indiana LLCs must file a Business Entity Report every two years (biennial, not annual). The report is due by the last day of the anniversary month of your LLC’s formation. The fee is $32 online or $50 by mail. Failure to file may result in administrative dissolution of your entity.
Operating Agreement
Indiana law does not require an LLC operating agreement, but having one is strongly recommended. It outlines member rights, profit/loss sharing, management structure, and what happens if a member leaves. Keep it with your business records – it does not need to be filed with the state.
Assumed Business Name (DBA)
If your LLC operates under a name different from its registered legal name, file a Certificate of Assumed Business Name with the Secretary of State via INBiz ($20 online / $30 by mail). Sole proprietors and general partnerships file with the County Recorder’s office in each county where they operate (~$25-$35 depending on the county).
Federal EIN (Employer Identification Number)
After forming your LLC, apply for a free EIN from the IRS at IRS.gov. You’ll receive it immediately when applying online. You need an EIN to open a business bank account, hire employees, and file taxes.
Step 3: Get Required Licenses & Permits
No Statewide General Business License
Indiana does not require a single statewide business license. Licensing is industry-specific, profession-specific, and location-specific. The Indiana Professional Licensing Agency (PLA) regulates over 40 professions including cosmetologists, plumbers, private investigators, and healthcare providers.
Local Licensing
Many cities and counties require local business licenses or permits. Indianapolis/Marion County requires business licenses through the Department of Business and Neighborhood Services. Zoning approval is typically required regardless of location. Contact your city clerk or county recorder for local requirements.
Registered Retail Merchant Certificate
If your business sells taxable goods or services, you need a Registered Retail Merchant Certificate (RRMC) from the Indiana Department of Revenue. The fee is $25 per business location (one-time, non-refundable). Register through INBiz using the BT-1 Business Tax Application. The certificate is valid for 2 years and renews automatically if all returns are filed.
Step 4: Register for State Taxes
Indiana State Income Tax
Indiana has a flat state income tax rate of 2.95% for 2026 (reduced from 3.00% in 2025). This rate applies to all individual income regardless of amount. Further reductions are scheduled, potentially dropping to 2.90% in 2027.
County Income Tax
All 92 Indiana counties levy their own income tax on top of the state rate. County rates range from 0.50% to 3.38% depending on your county of residence. Most counties charge between 1.00% and 2.50%. Combined state + county income tax rates typically range from 3.45% to 6.33%.
View all county tax rates at the Indiana DOR County Tax Information page.
Indiana Sales Tax
If your business sells taxable goods or services, register for a Registered Retail Merchant Certificate through INBiz.
- Sales tax rate: 7% statewide (no local add-ons)
- Taxable: Most tangible goods, prepared food, some services
- Exempt: Most services, unprepared groceries, prescription medications
- Registration: BT-1 application via INBiz ($25 per location)
- Note: Must file $0 returns even in periods with no sales activity
Food and Beverage Tax
Over 45 Indiana counties and cities levy an additional Food and Beverage (FAB) Tax of 1-2% on prepared food and drinks. Marion County (Indianapolis) charges 2%. Food businesses must register for FAB tax in each adopting jurisdiction where they operate.
Employer Taxes (If Hiring Employees)
Register for employer tax accounts through the BT-1 application on INBiz.
- Unemployment Insurance (UI) Tax: New employers start at 2.50% on the first $9,500 of each employee’s wages per year. Experience-rated range: 0.50%-9.40%.
- Withholding Tax: Register to withhold both state and county income taxes from employee paychecks.
Report new hires electronically to the Indiana New Hire Reporting Center within 20 business days of the hire date. Electronic filing is mandatory as of July 2024.
Step 5: Get Business Insurance
Workers’ Compensation Insurance
Indiana requires workers’ compensation insurance for employers with one or more employees. There is no minimum employee threshold – coverage is mandatory as soon as you have any employees (full-time, part-time, or seasonal).
| Status | Requirement |
|---|---|
| 1 or more employees | Workers’ comp is mandatory |
| Sole proprietor with no employees | Not required (may opt in voluntarily) |
| Independent contractors | Can file a certificate of exemption ($15) |
| Farm/agricultural laborers | Exempt |
| Domestic/casual workers | May elect optional coverage |
Penalties for non-compliance: Fines up to $100/day for operating without coverage. Willful failure is a misdemeanor (up to 1 year imprisonment and $5,000 fine). Uninsured employers may also be liable for double compensation to injured workers. Coverage is available through private carriers or through the Indiana Assigned Risk Pool for high-risk businesses.
General Liability Insurance
While not always legally mandated at the state level, general liability insurance is practically essential. Many clients, landlords, and government contracts require proof of coverage. Industry standard: $1 million per occurrence / $2 million aggregate.
