A corporation is a legal entity that exists separately from its owners (shareholders). When you form a corporation, you create a business structure that provides limited liability protection, which means the corporation's shareholders generally aren’t personally liable for the corporation's debts.

This legal separation between the business and its owners is one of the primary advantages of incorporating. Indiana corporations also benefit from relatively low corporate tax rates and several incentives to help support Hoosier businesses.

Why form a corporation in Indiana?

Indiana offers several advantages for businesses that choose to incorporate here. 

  • Limited liability protection. A corporation can enter contracts, take out loans, and buy property in its own name. This legal independence can help shareholders protect their personal assets from legal obligations related to the business. 
  • Greater business credibility. The "inc." or "corp." designation signals that your business is a formal legal entity with clear ownership and operational structures. This can enhance your business's credibility with customers, suppliers, and lenders. 
  • Potential tax advantages. Indiana corporations may benefit from deductions for business expenses, incentives, credits, and the ability to elect S Corporation status for pass-through taxation. 
  • More access to capital. Corporations can raise capital by issuing stock to investors. This makes it easier to attract investment and fund business growth. Indiana's corporate law allows for different classes of stock with varying rights and preferences.

How to start a corporation in Indiana: A step-by-step guide

To form a corporation in Indiana, you need to file articles of incorporation with the IN Secretary of State (SOS). This document creates your business’ legal existence, but requires you to gather some important information first. 

You can have LegalZoom register for you or do it yourself by following the steps below. 

Step 1: Confirm your business name is available

By law, the Secretary of State can’t register a corporation that doesn’t meet state name requirements:

  • Corporation names need to include the words "corporation," "incorporated," "company," or "limited," or the abbreviation "corp.," "inc.," "co.," or "ltd.".
  • If the business is a professional corporation, its name must include the words "professional service corporation," "professional corporation," or an abbreviation of either.
  • It can only include the word “medical” if all shareholders are licensed physicians. 
  • It must be distinguishable from other business names on record with the Indiana Secretary of State.

You can check if the name is available by doing an Indiana business entity search. The Indiana Secretary of State’s online database allows you to see if another business has already registered in Indiana under your desired name.

If the name’s available, you have the option to file a name reservation to hold it for up to 120 days. This gives you time to gather everything else you need to file articles of incorporation. The fee is $10 and you can file online through the SOS’s INBiz portal.

Step 2: Appoint an Indiana registered agent

Indiana requires every corporation to maintain a registered agent and registered office. A registered agent is a person or business that you appoint to receive legal and tax documents on behalf of your corporation. The registered office is their place of business. This role exists to ensure you’re aware of any vital legal notices that could affect your business.

Registered agents are responsible for receiving and forwarding these documents:

  • Service of process (notice of a legal action, such as a lawsuit)
  • Official notices from the Indiana Secretary of State
  • Tax notices and other government correspondence
  • Annual report reminders

Ensure your registered agent meets Indiana requirements:

  • Has a physical Indiana address (a P.O. box is not sufficient)
  • Is available during business hours (typically Monday through Friday, 9 a.m. to 5 p.m.)
  • Is an individual, general partnership, or registered business entity 
  • Consents to serve as your registered agent

Note that your corporation cannot serve as its own registered agent, but someone associated with your corporation (such as an employee, incorporator, or officer) can.

Step 3: Determine your stock structure

Indiana corporations must specify their stock structure in the articles of incorporation. A corporation can have different types of stock, called classes or series, with different rights and preferences, such as voting rights.

Here’s what you need to include in your articles:

  • Total number of authorized shares: The maximum number of shares the corporation is able to issue.
  • Par value of each share: The dollar value assigned to each share. Many corporations choose "no par value" for flexibility.
  • Classes of stock: If there is more than one class of shares, list the different classes and what distinguishes them.  
  • Rights and preferences: State the preferences, limitations, and relative rights of each class.

There are two main kinds of stock.

  1. Common stock: Usually carries voting rights and provides dividends.
  2. Preferred stock: May not have voting rights but has priority for dividends or liquidation proceeds.

Step 4: Prepare and file articles of incorporation

The articles of incorporation is the foundational document that creates your corporation under Indiana law. 

Here’s what you need to include:

  • Name and address of the corporation
  • Registered agent name and address
  • Stock structure and authorized shares
  • Names and addresses of incorporators (the person(s) responsible for signing and filing the articles of incorporation)

File online by creating an INBiz account or mail a paper copy with the filing fee to the Secretary of State. The filing fee is $98 online and $100 by mail. If everything checks out, the SOS will send you confirmation of your corporation’s existence. 

Step 5: Obtain state and federal tax IDs

Next, you’ll need to apply for an employer identification number (EIN). An EIN is a federal tax ID that your corporation requires in order to file federal taxes. It's also necessary for opening a business bank account, hiring employees, and obtaining certain licenses and permits.

You can apply for free online through the Internal Revenue Service (IRS) or have LegalZoom handle it for you

Depending on your business activities, you may also need to register with the Indiana Department of Revenue (DOR) for state taxes:

  • Corporate income tax: 4.9%. S and C corporations report differently, so make sure you file the correct form for your business type. 
  • Sales Tax: 7% for businesses that sell goods or tangible personal property.
  • Withholding tax: For businesses that plan to hire employees or have nonresident shareholders. 

These are just the most common, but certain professions or business activities will require you to sign up for additional taxes—a CPA or tax advisor can help you know for sure. You can register for state taxes online through the Indiana DOR's online filing portal, INTIME.

Step 6: Open a corporate bank account

This step is helpful to maintain your limited liability status and protect your personal assets. A separate business bank account will also help ensure your business keeps proper financial records.

Here’s what you’ll generally need:

  • Certificate of incorporation
  • EIN
  • Corporate bylaws
  • Board resolution authorizing account opening
  • Identification for authorized signers

Step 7: Hold an organizational meeting and adopt bylaws

To set up the formal structure of your corporation, hold a meeting to do the following:

A corporation’s bylaws describe its internal rules and operating procedures. You don’t need bylaws to incorporate, but Indiana law does require the initial incorporators or the board of directors to establish them once the corporation exists. 

Your bylaws can contain any provisions that address how to manage and regulate your corporation. But, those provisions can’t contradict your articles of incorporation or Indiana law. These are some common provisions to consider: 

  • Number of directors and officers
  • Duties and responsibilities of directors and officers
  • Procedures for shareholder meetings
  • Voting procedures and quorum requirements
  • Stock transfer restrictions
  • Amendment procedures
  • Indemnification provisions

Indiana compliance requirements

In addition to keeping up with taxes and licenses, corporations need to file an Indiana business entity report (BER) to maintain compliance with the state. This is a biennial report that’s due every other year on the anniversary of incorporation. The purpose of the BER is to update the SOS on your business’ basic information. 

The filing fee depends on how you choose to submit your report. File online for $32 or mail your BER to the Secretary of State along with a $50 filing fee.

Genaro was great!

Genaro was a great listener, remembered everything we spoke about and then walked me through the process of moving my LLC into a Corporation. Glad I called rather than try to do online - we got it all done in about 20 minutes.
