S Corporation Restrictions

S corps have several restrictions, such as being limited to one class of stock and 100 shareholders. Read our What Is an S Corporation guide for full details.

Are S Corp Tax Advantages Right for You?

An S corporation is a tax designation that can be elected by a limited liability company (LLC) or corporation. With an S corp, business owners are considered employees of the company and must receive a reasonable salary. Since all S corps technically have employees, the s corp must run payroll. 

In order to benefit from an Indiana S corp tax designation, your business needs to make enough money to offset payroll expenses. Furthermore, S corps are beneficial for business owners who take large distributions in addition to their salary.

How to Form an Indiana S Corp

There are two main ways to start an S corp:

  • By forming an LLC and electing S corp tax status from the Internal Revenue Service (IRS) when you request your employee identification number (EIN)
  • By forming a corporation and electing S corp status from the IRS

We recommend forming an LLC because it’s simpler and more cost-effective.

Steps for Forming an LLC and Electing S Corp Status in Indiana

Starting an Indiana LLC and electing S corp tax status is easy. You can use our guides to start an LLC with the S corp status yourself, or you can hire a service provider like Northwest to guide you through this process.

There are five basic steps to start an LLC and elect S corp status:

Step 1: Name Your LLC

Step 2: Choose a Registered Agent

Step 3: File the Articles of Organization

Step 4: Create an Operating Agreement

Step 5: Get an EIN and File Form 2553 to Elect S Corp Tax Status

Step 1: Name Your LLC

Choosing a company name is the first and most important step in starting your LLC in Indiana.

Be sure to choose a name that complies with Indiana naming requirements and is easily searchable by potential clients.

1. Follow the naming guidelines for an Indiana LLC:

  • Your name must include the phrase “limited liability company” or one of its abbreviations (LLC or L.L.C.).
  • Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
  • You must have approval from the Indiana Department of Financial Institutions to use the word “bank” (or any variation) in your LLC’s name.
  • Your name must be distinguishable from any existing business in the state. This includes Indiana reserved business names.

You can also read the Indiana state statute about LLC naming guidelines for more information.

2. Is the name available in Indiana? You can use the business search on the Indiana INBiz website to see if your desired LLC name is available.

3. Is the URL available? We recommend checking to see if your business name is available as a web domain. Even if you don't plan to create a business website today, you may want to buy the URL in order to prevent others from acquiring it.

Step 2: Choose Your Indiana Registered Agent

You must elect a registered agent for your Indiana LLC.

An LLC registered agent will accept legal documents and tax notices on your LLC's behalf. You will list your registered agent when you file your LLC's Articles of Organization.

Many business owners choose to hire a registered agent service. Many of these services will form your LLC for a small fee and include the first year of registered agent services for free.

Step 3: File the Indiana LLC Articles of Organization

The Indiana Articles of Organization is used to officially register an LLC.

Keep Your Indiana S Corp Compliant

After forming your business and electing the S corp tax designation, you’ll want to make sure you keep it in good standing by following all state and local laws. This requires filing a Business Entity Report with the state every two years as well as paying both federal and local taxes. 

Indiana S Corp Business Entity Report

Every two years, your S corp must file a Business Entity Report with the Indiana Secretary of State. This report is due at the end of the month in which you originally registered your business. If you formed your business in October 2017, for example, you’ll need to file a business entity report by October 31 of every odd-numbered year.

Read our step-by-step Indiana Business Entity Report guide to learn more about filing your report.

Indiana S Corp Taxes

S corporations benefit from pass-through taxation, meaning the business’s profits pass-through to S corp owners’ individual tax returns. S corp owners make money from their reasonable salary and distributions, and Indiana S corp owners can expect to pay the following taxes:

Federal Self-Employment Taxes

Self-employment taxes cover social security and medicare. The self-employment tax rate is 15.3%, and money you take as salary will be subjected to the self-employment tax. However, distributions are not subjected to this tax.

Federal Income Taxes

Your federal income taxes will depend on your tax bracket, and the cutoffs for individual tax brackets as well as the percent owed will change each year. Both your salary and distributions are subjected to federal income tax.

Indiana Income Taxes

Indiana has a flat 3.23% income tax rate. Many local jurisdictions levy an additional income tax rate on top of this. Compared to other states, Indiana’s 3.23% statewide income tax rate is fairly low. 

Register for Indiana Business Taxes

Before you begin doing business in the state, you must register your business for Indiana state taxes.

Indiana Sales and Use Tax

Indiana has a 7% statewide sales tax. Unlike some other states, local jurisdictions in Indiana don’t levy additional sales taxes on top of this. 

Additional State Taxes

The Indiana Department of Revenue oversees taxation for the state. Depending on your business’s location, number of employees, and industry, you may have to register for additional state-specific permits and taxes.

 Some examples of these additional state taxes and fees include:

  • Alcoholic Beverage Tax
  • Fireworks Tax
  • Gasoline Tax
  • Public Utility Tax
  • Special Fuel Tax

Visit the Indiana Department of Revenue website to learn more.

Indiana Local Taxes

Regardless of your business’s location in Indiana, local jurisdictions may have their own laws that can impact how your business operates. Make sure to research local laws and regulations to ensure your business complies with them.

Start an Indiana S Corp FAQ

An S corporation (S corp) is a tax designation that an LLC or a corporation can elect.

No. The default taxes for an LLC and taxes for an S corp are not the same.

With an S corp, owners pay personal income tax and self-employment tax on a predetermined salary. They may then withdraw any remaining profits from the business as a “distribution,” which isn’t subject to self-employment tax.

With an LLC, all company profits pass through to the owners’ personal tax returns, and then the owners must pay personal income tax and self-employment tax on the entire amount.

S corp owners are required to earn a “reasonable” salary, which basically means a fair market rate based on the individual’s qualifications as well as their duties and responsibilities at the company. The purpose of this requirement is to prevent S corp owners from paying themselves an artificially low salary in order to pay less self-employment tax.

A distribution is a dividend that a shareholder/owner can take from the business profits that remain after a company pays all of its employee salaries. Shareholders must pay personal income tax on distributions, but distributions aren’t subject to self-employment tax.

LLCs and corporations that operate under a “doing business as” (DBA) name can choose the S corp election.

Although there’s no perfect place for you to start your business, you should consider setting it up where you plan to operate. Forming an S corp in Indiana can prove beneficial because the reduced tax burden means you can invest more money into driving your business’s growth.

If you already set up your business as an LLC, you’ll have the opportunity to file an additional form to elect S corp status. Because the process is nearly identical, the change is simple. As long as your business meets the requirements for an S corp, you just need to file Form 2553 with the IRS.
