How to Start a Business in Indiana

Your complete 2026 guide to business registration, state taxes, licenses, and key industries in Indiana.

Starting a business in Indiana offers entrepreneurs a straightforward path through the state's business-friendly regulatory environment. Whether you're launching a small family operation or establishing a larger enterprise, understanding Indiana's requirements for business registration, taxation, licensing, and industry opportunities will help you navigate the startup process effectively.

The first step in launching your Indiana business is selecting and registering your business entity. Indiana recognizes several business structures, each with different liability protections, tax implications, and operational requirements. A sole proprietorship is the simplest structure, allowing one person to operate a business with minimal formalities, though it offers no personal liability protection. Partnerships enable multiple owners to share responsibilities and profits while maintaining flexibility, but partners remain personally liable for business debts. Limited Liability Companies, or LLCs, provide personal liability protection while offering tax flexibility and simpler administration than corporations. Corporations are more formal entities that provide strong liability protection but require more extensive record-keeping and compliance procedures.

Registering your chosen business entity in Indiana is handled through the Secretary of State's office. The registration process typically involves preparing formation documents specific to your entity type, such as Articles of Organization for an LLC or Articles of Incorporation for a corporation, and submitting them along with the appropriate fees. The Secretary of State's website contains forms, filing instructions, and current fee information for each entity type. Most businesses also need to appoint a registered agent—an individual or entity designated to receive legal documents on behalf of your business. This person or company must have a physical address in Indiana and be available during business hours.

Indiana's tax landscape is an important consideration for any new business owner. Indiana has a state income tax that applies to business profits, with rates and brackets set by state law. The state also imposes sales tax on most tangible goods sold in Indiana, and businesses that make retail sales generally must register with the Department of Revenue and collect sales tax from customers. Additionally, Indiana has a franchise tax system, though many small businesses may qualify for exemptions based on their structure or income level. It's advisable to consult with a tax professional or check the current tax regulations through the Indiana Department of Revenue to understand your specific obligations and any available deductions or credits.

Beyond state taxes, you'll need to address federal tax requirements. All businesses must obtain an Employer Identification Number from the Internal Revenue Service, even sole proprietorships without employees. If you plan to hire employees, you'll need to register with Indiana's unemployment insurance program and withhold federal and state taxes from employee wages.

Licensing and permitting requirements vary significantly based on your industry and location. Most businesses need some form of business license, which may be obtained at the state level, county level, or municipally, depending on your business type and location. Indianapolis, as Indiana's largest city and capital, has its own licensing requirements and processes that differ from other communities. Certain industries require specialized permits or licenses: food service businesses need health department permits, contractors need licensing from the Indiana Construction Industries Board, healthcare providers need appropriate professional licenses, and childcare facilities require licensing from the Department of Child Services. Environmental businesses, financial institutions, and other regulated industries have specific state board requirements. You should contact your local city or county government office to determine which specific permits and licenses apply to your business.

Indiana's economy is diverse and offers opportunities across multiple sectors. The state has traditionally been strong in manufacturing, particularly automotive production and metal fabrication, and these industries continue to be significant. However, Indiana has also developed robust sectors in logistics and distribution, life sciences and pharmaceutical manufacturing, agriculture and food processing, and advanced manufacturing technology. Indianapolis serves as a major hub for these industries and offers numerous resources for entrepreneurs, including business development organizations and networking opportunities. The state government has also created programs to support technology startups and innovation-driven businesses, making these emerging sectors increasingly accessible to new entrepreneurs.

As you prepare to launch your Indiana business, start by visiting the Secretary of State's website for entity formation information, contact the Indiana Department of Revenue to understand your tax obligations, and reach out to your local chamber of commerce or economic development office for guidance on industry-specific requirements. Taking time to properly register and structure your business from the beginning will establish a strong foundation for long-term success.
