How to Start an LLC in Illinois

Illinois ranks near the top third of best states to start a business and ranks very high for categories like access to capital, low cost of living, and affordable cost of doing business. If you are looking to start an LLC in Illinois, this guide will walk you through the step-by-step process to help get your business up and running in no time.

  • LLCs provide liability protection for business owners, meaning that the owners’ assets will not be at risk.
  • Easy to set up and manage
  • One person may form an LLC

If you are exploring starting a business or perhaps you are already in business as a sole proprietor it is a good idea to form an LLC. If you are operating a business without an LLC you could be placing yourself and your personal assets at risk. 

While it is not required to form an LLC before starting a business the benefits include accounting and tax standardization, limited liability risk right away, and it will be easier to stay organized since all of your business-related expenses will be tied to one business bank account.

The first step in starting an LLC is to select a business name. It is essential to choose a business name that is unique from existing entities.

The Illinois Secretary of State maintains a database of business entities registered in Illinois that is free for the public to search.

Naming considerations

Your Illinois LLC must contain “Limited Liability Company” or include the abbreviation LLC or LLC. Prefixes, suffixes, and plural versions of an existing entity name do not make it unique.

For instance, if you wanted to start a breakfast restaurant called Pancake Cafe LLC you would want to make sure there wasn’t a similar sounding name like Pancakehouse Breakfast Cafe etc. The intent with naming rules is to create a clearly distinguishable name that avoids confusion for the public so if you find a name that is somewhat similar to the one you are considering it is probably best to move on to another name idea.

If you are struggling to develop an Illinois LLC name, one option is to use a business name generator, which can help come up with hundreds of name suggestions in seconds.

If you intend on using your business for a commercial purpose you will want to perform a trademark search before selecting your Illinois business name. A trademark will help protect against infringement of unauthorized use of your business name and logo without your permission and can eventually become a valuable asset if your business grows.

Avoid using a trademarked or similar name to an existing business to protect yourself.

Find out if your proposed business name is available by conducting a trademark search online at the US Patent & Trademark Office. 

Determine if you want to use a DBA name

A DBA is a registered “Doing Business As” name and can be used instead of the legal LLC business entity name. 

A DBA allows you to have a name for your business that reflects what it does or who its customers are. Business owners use their company’s DBA names on checks, orders, contracts, and correspondence when doing business.  

Some of the main benefits of a DBA:

  • Flexibility: If you have your LLC established, you can use DBA names instead of creating separate entities for each new venture. 
  • Branding: A DBA name is easier to brand and identify for customers.
  • Expansion: It is easy to file DBAs in different geographical locations to target other customers and appear hyper-focused in your marketing.

You do not need to operate under a DBA if you use your Illinois business name for all business purposes. However, using a DBA name will not affect your Illinois LLC name registration.

Register the domain name

Once you decide on a business name, check to ensure that the domain name is available. can show you which domain extensions are available for your business name.

Although .com domain names are ideal, extensions like .net, .co, and .biz are becoming more commonplace

Register social media profiles

It is vital to have a solid social media presence in today’s business environment. So be sure to register for your business name on the different social media platforms ahead of time so that no one can sign up for them.

After choosing a name, start the registration process online at the Illinois Secretary of State website.

Registering your LLC in Illinois is a relatively straightforward and quick process.

If you are not going to be your Illinois LLC’s registered agent, find a substitute Illinois resident or company to serve in this role. Be sure that the registered agent’s address is included in all your business documents and correspondence if you intend to use a different registered office.

Apply for an EIN

The IRS requires each LLC to have its own unique employer identification number. The Internal Revenue Service website can generate a federal tax identification number. An EIN makes it easy to file your business taxes and stay in compliance with the IRS and is similar to a Social Security number for your business.

EIN’s also add credibility to your business and are required for compliance purposes from time to time by companies that have to pay you for goods and services. An EIN is also required to open a business bank account and will help you establish business credit in the event you need to take out a business loan.

Start a business bank account

A business bank account is required for LLCs to start conducting business. Therefore, it is highly recommended that you start a low-risk bank account to start receiving income and paying any start-up expenses.

After the LLC has been established, your business bank account will be used for payroll, payment of bills, a deposit of earnings from your business, and any other financial transactions your business may have.

Back office tasks such as bookkeeping can also be performed on your start-up bank account to keep start-up costs low.
