In addition to this LLC filing fee, there are other costs to be aware of when forming an Illinois LLC (Limited Liability Company).

Costs to forming an Illinois LLC

Illinois LLC Articles of Organization Filing Fee ($150)

Starting an LLC costs $150 in Illinois. This is the state filing fee for a document called the Illinois Articles of Organization.

The Articles of Organization are filed with the Illinois Secretary of State. And once approved, this is what creates your LLC. The easiest way to submit the Articles of Organization is by filing online.

The $150 fee is a one-time Illinois LLC cost. You don’t have to pay any monthly (or annual) fees to start your Illinois LLC.

Note: LLCs are the most common business structure used in Illinois. They are the most popular business entity because they offer liability protection for the LLC owners.

Depending on the state, the Articles of Organization form is sometimes called a Certificate of Organization or Certificate of Formation. Articles of Organization is the most common name – but they all mean the same thing: the form used to create your LLC.

Illinois business name cost ($0)

Naming your Limited Liability Company doesn’t cost anything. Your Illinois LLC Name is approved (at no extra cost) when your Articles of Organization filing is approved by the state.

You may have read online that LLC Name Reservations are required. However, this is not true in most states. Illinois doesn’t  require a Name Reservation to form an LLC. You simply enter your desired, unique LLC name on your Articles of Organization filing. There’s no additional form to file or fee to pay.

Make sure your LLC name complies with the Illinois naming requirements and isn’t already being used by another business.

How much does a DBA cost? (varies)

In Illinois, a DBA is filed with the county where your LLC operates. So the cost of a DBA will vary depending on where your LLC does business. The filing fees for DBAs are optional, however, because DBAs aren’t required.

Note: A DBA is sometimes called a Trade Name, Fictitious Name, Assumed Name or Fictitious Business Name. They all mean the same thing.

Tip: You aren’t required to get a DBA for your LLC. It’s optional. For more information, read our article: Do I need a DBA?

Illinois Registered Agent Fee ($0 or $125/year)

Illinois law requires that you designate a Registered Agent when forming your LLC. But there’s no filing fee when you list a Registered Agent on the formation documents.

An Illinois Registered Agent is a person or company who receives legal documents and state notices for your LLC. A Registered Agent needs a street address in the state and should generally be available during normal business hours.

There is no additional cost if you will be your own Registered Agent, or have someone you know be your LLC’s Registered Agent. This could be one of your business partners, or a friend or family member.

However, you have the option of hiring a Registered Agent service. This will cost you between $100 to $300 per year. But Registered Agent service companies offer other helpful business services and can protect your privacy.

Hiring a Registered Agent service is a good idea if:

  • You don’t have an address in the state (Illinois law requires Registered Agents to have a physical street address in the state)
  • You want to keep your address off public record (depending on which company you hire, you may be able to use their address to keep your address private)

Special offer: Hire Northwest to form your LLC ($39 + state fee), and you'll get a free year of Registered Agent service.

LLC Operating Agreement Fee ($0)

An Illinois LLC Operating Agreement is a written contract between the LLC Members. Operating Agreements include detailed information about LLC ownership, how the LLC is managed, and how profits are distributed.

Single-Member LLCs and Multi-Member LLCs should draft an Operating Agreement, keep it with their business records, and give a copy to each Member.

Most websites charge $50 to $200 for LLC Operating Agreements.

Here at LLC University®, we offer free LLC Operating Agreement templates for all types of LLCs.

LLC EIN Number Fee ($0)

An EIN Number is also known as an Employer Identification Number (EIN) or a Federal Employer Identification Number (FEIN).

This number is used to file income taxes, to open an LLC bank account, and to hire employees (if applicable).

Although many websites charge a service fee to get an EIN for your LLC, it can actually be done for free.

You can obtain an EIN for your LLC from the Internal Revenue Service (IRS) at no cost. The online filing can be completed in a few minutes.

Note: The EIN Application is the only thing you have to file with the Federal government. Everything else about your LLC is done at the state level.

Illinois LLC Annual Report Fee ($75/year)

Illinois requires you to keep your LLC’s information up to date by filing an Annual Report.

This keeps your Illinois LLC in good standing and in compliance with state law so it can continue operating. You simply confirm the information on the Annual Report, file it with the Illinois Secretary of State, and pay the Illinois Annual Report fee.

The Illinois LLC Annual Report costs $75 per year. This fee is paid every year for the life of your LLC.

Illinois Business License and Permit Fees (varies)

Depending on where your LLC does business in Illinois and the industry you’re in, you may need to obtain additional Business Licenses or Permits. For example, you may need to get a City Business Permit.

The costs for these other business licenses or permits will vary depending on location and industry, but usually the fees are not very high. Some licenses and permits are issued at the state level, and others are issued by a municipality (the town, city, or county).

LLC Taxes (varies)

There are many different types of Illinois LLC taxes that owners must pay, so this annual cost varies widely.

Some of the taxes LLC owners pay include:

  • Federal taxes
  • State income tax
  • Local income tax
  • Business taxes
  • Self-employment taxes
  • Sales tax
  • Payroll tax (if you have employees)
  • Property tax (if the LLC owns property)

Your Illinois LLC taxes depend on your industry and amount of business activity, so we’re not able to provide an estimate. Every business is different, and your specific circumstances determine what taxes apply to your LLC.

Note: By default, a Single-Member LLC is taxed like a Sole Proprietorship. And a Multi-Member LLC is taxed like a Partnership.

Hiring an Accountant

How much your small business pays in taxes is best determined by working with a qualified accountant in Illinois.

The amount you’ll pay your accountant will vary. However, most accountants will charge $300 per year for a simple tax return, or up to $900 for more detailed filings.

Note: We recommend speaking with a few accountants in Illinois to make sure they can help you meet all of your federal, state, and local tax obligations. We offer detailed tips on How to Find an Accountant.

It varies. Some banks charge monthly fees ($10 to $20 per month), but these can sometimes be avoided by meeting certain requirements. For example, if you make a certain number of direct deposits or maintain a specified minimum balance, then they’ll waive the monthly fees.

Before you open your LLC business bank account, we recommend calling and asking if there are ways to avoid the monthly maintenance fees.

How much is a Foreign LLC in Illinois?

A Foreign LLC is an LLC formed in another state that must register (aka Foreign Qualify) in Illinois. This is because the LLC is doing business in both states.

If you form an LLC in Illinois, it is called a “Domestic LLC”. If you formed your LLC in another state, it would be a Foreign LLC once you register it in Illinois.

Is Illinois a good state for an LLC?

Yes, Illinois is a great state to start a business. Illinois doesn’t charge a state business license fee, has quick approval times and helpful representatives at the Secretary of State if you have questions.

However, the most important factors in deciding where to start a business are where you live and where your LLC operates (aka where you transact business)

Meaning, if you live in or do business in Illinois, then you should start your business in Illinois. While many websites talk about tax rates and advantages of certain states, none of that applies if it’s not the state where you live and do business. And just because a certain state has cheaper LLC fees doesn’t mean it’s a good idea to form your LLC there.

For example, if you form an LLC in Delaware, but live in and conduct business in Illinois, you’ll also need to register your Delaware LLC in Illinois (and pay fees). And you’ll end up paying Illinois taxes anyway. This ends up leading to more costs and more headaches with no advantages.

In summary, if you are an Illinois resident, then yes, Illinois is the best state to form an LLC. If you don’t live in and do business in Illinois, then no, Illinois probably isn’t a good state to start an LLC.
