How Much Does It Cost to Start an LLC in Illinois

If you’re starting a business in Illinois, you may consider creating a limited liability company (LLC).  Before diving in, you should know that this comes with costs. 

To prepare you, this handy guide details all you need to know about launching an LLC in Illinois.

Illinois LLC Costs

LLC Registration Fee$150
Business License FeesVary by localities and type of business
DBA feeAnnual, varies by year
Annual Report Fee$75

Name Reservation Fee

One of the first things to consider will be what to name your LLC. Once you’ve chosen the perfect name, you can reserve it with the state until you’re ready to form your LLC officially.

To do so, you’ll need to make sure the name is available. Here’s how:

1. Check for availability in Illinois

To ensure the business name is available, go to the Secretary of State’s website and enter the names you like as well as similar names. You don’t want a business name that can easily be confused with other Illinois businesses.

2. Check Illinois LLC name regulations

In Illinois, your LLC name must include the phrase “limited liability company,” or an abbreviation such as LLC or L.L.C.. Your name cannot include words that could confuse your LLC with a government agency or words like bank, insurance, university, or fiduciary without state approval. 

Additionally, your name must be distinguishable from all other business names in Illinois and cannot contain any terms or abbreviations that imply the LLC is a corporation or partnership.

3. Check Trademarks

It’s a good idea to ensure the name has not been trademarked. Check with the US Patent and Trademark Office to ensure the name is available nationally. 

4. Check domain name availability

You’ll want to ensure the domain name is available. You can check at a site like and use .com or .org, as those give your business more credibility.

5. Google it

Do a Google search to ensure the name is not being used in the U.S. or internationally. This is important if planning to have a strong online presence for your business.  

Once you’ve done your due diligence and know your preferred business name is available, you can reserve the name with the state using this name reservation form.

The fee is $25, and the name will be held for 90 days.

Cost to Register Your LLC in State

To officially form your LLC, you’ll file articles of organization with the state of Illinois by visiting the Secretary of State’s website. You’ll need the following information:

  • Business name
  • Business address
  • Registered agent name and address
  • Business purpose
  • Manager or member names and addresses
  • Organizer names and addresses

In Illinois, the fee is $150, and your LLC should be approved in seven to 10 business days.

Business Licenses and Permits

Your LLC may also need to obtain licenses and permits at the federal, state, and local levels. These, of course, come with varying fees. 

At the federal level, licenses and permits are generally industry-specific and may include health licenses and permits from the Occupational Safety and Health Administration (OSHA).  

You may need a general business license to operate at the state level. If you sell tangible goods or services subject to sales tax, you’ll need a sales tax license, also known as a seller’s permit. 

Check the SBA guide for specific licenses required for your business. 

Here are some standard licenses and permits you may need:

  • Industry-specific licenses for certain professions and industries such as construction, plumbing, electrical, childcare, food handling, liquor, architecture, and finance
  • Building and zoning permits
  • Doing business as (DBA) permit if you’re doing business using a name other than your LLC name
  • Health licenses and permits at federal, state, and local levels
  • Fire permits
  • Sign permits

This is a significant step in the LLC formation process, so make sure to check with your state and local government offices to find out all the licenses and permits that you need and their costs. You could face steep fines and penalties if you operate without the proper licenses and permits.

If you need help, it’s a good idea to consult with a business attorney to ensure you’re in full compliance. You can also use a service like MyCorporation to do the research and provide you with all the forms you need to license your business. 

Doing Business As (DBA) Name

If you plan to do business under a name that is not your LLC, you’ll need to register a “doing business as,” or DBA, name. 

To do so, you’ll visit the Secretary of State’s website. The cost to register a DBA, known as an assumed name in Illinois, is an annual fee as follows:

  • $150 — for each year or part thereof ending in 0 or 5
  • $120 — for each year or part thereof ending in 1 or 6
  • $90 — for each year or part thereof ending in 2 or 7
  • $60 — for each year or part thereof ending in 3 or 8
  • $30 — for each year or part thereof ending in 4 or 9

Annual Reports

In Illinois, your LLC is required to file an annual report to verify your business information and confirm you’re still doing business.

The report can be filed at the Secretary of State’s website; the fee is $75.

In Closing

Starting an LLC in Illinois is instead a complicated process that includes a handful of fees. There are several hoops to jump through, but the benefits of ensuring your LLC is properly registered, and fully compliant are huge, while the alternative risks significant penalties. LLC formation can be daunting, so many entrepreneurs prefer a professional service like ZenBusiness. This ensures the process is done correctly, saving time and giving you peace of mind.
