Creating an LLC offers cost and efficiency advantages for small businesses. Without proper guidance, the process can be complex.

Drawing from my extensive experience in business formation and supported by a team of legal experts, we've crafted a practical guide, informed by real-world insights and Illinois law research.

This resource eliminates unnecessary confusion and empowers you to establish an Illinois-based LLC seamlessly, allowing you to concentrate on your business growth confidently.

Quick Summary

  • To start an LLC in Illinois, you need to choose a business name, hire a registered agent, file articles of organization, create an LLC operating agreement, and obtain an EIN.
  • Forming an LLC in the state of Alabama takes 3-4 weeks.
  • To avoid incurring financial losses, LLC owners opt for general liability insurance.


Illinois LLC Setup

Setting up an LLC is a pretty straightforward process. To open an LLC, you will need to complete a few steps before everything sets into place.

Step 1: Choose Your Illinois LLC Business Name

Choosing a name for your LLC is probably the first thing you should do. Name requirements for business entities in Illinois are governed by state statutes.

These requirements include that the name you choose cannot be exactly like another active business entity in your county or anywhere else in the country.

It also must end with a title such as "LLC," "Limited Liability Company," etc., so it is easy to determine what kind of entity you have. Keep in mind that variations "Co." and "Ltd." are not allowed in the state of Illinois.

You can search the state's name database at the Illinois Secretary of State Department of Business Services [1].

If your business name does not comply with certain requirements, then you may also be required to reserve it before proceeding and pay another $25 fee for this.

The reservations can last for up to 3 months, and they are filed with the Department of Business Services through an Application to Reserve a Name.

Step 2: Hire a Illinois Registered Agent

A registered agent for an LLC is an individual or service that keeps an office in Illinois and is authorized to accept legal documents on your behalf. They help with various business tasks, such as handling operating agreements and other vital documents.

They also must be willing to serve as the official contact for any lawsuits filed against them, should they arise. The registered agent can either be a company or an individual who meets this requirement.

Another requirement for an Illinois registered agent is that they must have a physical street address in Illinois.

The Illinois Chamber of Commerce website has a list of registered agents who meet these requirements and offer services for LLCs starting. The list is updated regularly.

Step 3: File Illinois LLC Articles of Organization

File LLC Articles of Organization with the Illinois Secretary of State to form an LLC. The articles list information about your business name, business structure, address, and registered agent service.

A registered agent must also include a statement that no other articles have been submitted for filing within 30 days before or after this document was filed.

Creating the Articles of Organization requires filling out an online application, which includes uploading articles upon submission, or you can file by mail.

The LLC Articles of Organization represent a legal document and should be prepared and reviewed with care, thus requiring a registered agent if you aren't as well-versed.

Articles of Organization should also state whether your LLC will be manager-managed or member-managed.

You must include a check for $150 made out to the Illinois Secretary of State with your articles of organization, whether you choose to submit them by mail or online.

The processing time for your Illinois LLC typically takes ten business days, although you can opt for expedited processing at an additional fee.

If you already have an LLC in another state, you will have to file new Articles of Organization with the state of Illinois and register as a Foreign LLC.

Step 4: Create Illinois LLC Operating Agreement

Operating agreements are important for LLCs and should include:

  • What percentage of ownership does each member have in the LLC?
  • Share of profits and losses.
  • How much LLC capital contributions are required from each LLC member?
  • The rights & responsibilities of LLC members to manage the business operations.
  • Dissolution steps in case LLC members wish to end the LLC.
  • How LLC profits will be shared among LLC members and whether or not an LLC member would get a salary from company income or if all profit goes directly into their business bank account.

LLC members can prepare an Illinois LLC operating agreement on their own or hire a professional to do it.

LLC operating agreements represent internal legal documents that don't have to be filed with the state. However, having an operating agreement will help LLC members avoid unnecessary misunderstandings and disagreements.

For example, LLCs that do not have an operating agreement can face problems when one of the LLC's members decides to leave the business entity (and take his share of profits with them).

Without a written LLC Operating Agreement, it is difficult to prove whether or not this particular person had an equal right to those profits.

The structure of an LLC Operating Agreement is similar to the agreement that LLC members would draw up as part of a buy-sell arrangement or in case they were selling their ownership stakes within an LLC.

Step 5: Obtain Employer Identification Number (EIN)

Obtain a Federal Employer Identification Number (EIN), also called a federal tax identification number.

An EIN can be obtained free of charge by completing Form SS-4 online at the Internal Revenue Service website.

An Employer Identification Number is required if your LLC has any employees or plans to hire employees in the future.

If your business doesn't have employees or you own a sole proprietorship or a single-member LLC, you don't need an EIN. Single-member LLCs are required to file Form REG-1, though.

EINs are also required to file state and federal taxes or open a business bank account for your LLC, regardless of its structure and elected taxation.

Once you apply for an Employer Identification Number, you will have to choose one of the taxation options available for Illinois LLCs.

S corporation status offers reduced federal tax obligations, but the majority of LLCs usually opt for default tax status.

What to Expect After Registering an LLC?

After registering an LLC, you will have the option to run it as a corporation, limited partnership, or sole proprietorship.

No matter for what reason you opt for an LLC business structure, financial and professional regulations will be in place at all times.

Limited liability companies are designed to give you personal liability protection, which means that business debts are not included in your personal assets.

This is why most owners decide on general liability insurance to avoid incurring financial losses if their company faces a legal suit over some kind of damage they have caused.

Annual Filing Requirements for Illinois LLCs

Annual reports are something that you have to deal with once you form an LLC.

The State of Illinois requires LLCs to submit an annual report. Illinois annual report for an LLC may be filed online at the Illinois Secretary of State website or by mail (through Form LLC-50.1).

Annual reports will help your business stay in good standing with the State of Illinois. It is one of the main reasons why it's important to have a registered agent in the first place.

A registered agent service will notify you when your annual report is due so you can file it on time.

If the LLC fails to submit an Annual Report, it will be subject to a fine for each year that passes without filing its report.

If this happens, they may also face additional fines and penalties and lose good standing with the State of Illinois.

In Illinois, LLCs are taxed differently than in other states. The state taxes personal property separately, and these tax obligations are known as a personal property replacement tax.

Unless you elect corporate taxation, you will be taxed at the rate of 1.5 percent of your net income.

The state of Illinois requires that if your LLC sells products to customers in the state, you must collect and pay sales tax.

This implies that you'll need to register with the Illinois Department of Revenue and then make sales tax payments for items sold regularly.

The state of Illinois has a 6.25 percent sales tax rate on general items and a 1% food, medicine, and medical equipment tax.

Because some local governments are permitted to impose their own Illinois business taxes, the sales tax rate may be higher in certain counties. To check individual tax rates for Illinois, make sure to check Illinois Tax Rate Finder.

Lastly, state employer taxes are required for LLCs in Illinois. Once you register your Illinois LLC with the Illinois Department of Revenue, you'll have to pay employer withholding tax, either on paper or online.

Make sure to follow the guidelines provided by the IDOR official website.

How Are Illinois LLCs Taxed?

Licenses and Permits for Illinois LLCs

Business licenses and permits for LLCs are something that needs to be followed, but only under one condition: all LLC members must be licensed or registered to perform the professional service for which the professional limited liability company was created.

The Illinois Department of Financial and Professional Regulation's website (IDFPR) is the ideal location to begin your research.

This page has an alphabetical list of all the regulated professions and links to business license applications and assistance so that you can check which business licenses and permits your LLC needs.

Why Should I Form an LLC in Illinois?

By creating an Illinois limited liability company, your business is treated as a separate legal entity that can own property, enter into contracts, pay taxes, sue, or be sued.

Another reason why Illinois is such a popular state for LLCs is because of how easy it is to form and maintain an LLC.

It only takes a few minutes for you to file your Illinois Articles of Organization with the Illinois Secretary of State, all while avoiding complicated tax forms and extensive filings like many other states require.

Lastly, Illinois LLCs are not expensive to set up, making this state attractive to those business owners who don't want to spend a lot of money before they even get off the ground.
