Form an LLC

Step 1) Verify & Secure a Name

Choose a Business Name

First off, in order to launch a successful Illinois LLC, you need to give it the right name. Your business name needs to be catchy for branding purposes and legitimate for legal purposes. We go into depth on this topic in our LLC naming guide, but we’ll go over the legal basics below.

Legally, your business name must:

  • Contain the words limited liability companylimited company, or the abbreviation LLC or L.L.C.
  • Not contain restricted words or phrases (these often include words like bank, attorney, and university) without proper approval.
  • Be distinguishable from any other entity or trade name registered in Illinois.

If you’re having trouble coming up with a name that captures your brand, don’t let that stop you from forming your LLC. For now, you can focus on the legal requirements and consider applying for an assumed business name after you’ve nailed down your branding.

What To Do:

Once you’ve decided what you’d like to call your LLC in Illinois, do a business name search to find out whether or not it’s in the cards. If your business name is available, you’ll be able to lock it down when you file your Articles of Organization.

Quick Note: Before you commit 100% to a name, you should see if there’s a decent URL available. Use GoDaddy to search for your options. If there’s a quality domain name for purchase, we advise buying it right away because even if launching a business website isn’t on your radar right now, it’s going to be soon.

Step 2) Choose A Registered Agent

Choose a Registered AgentWhen you file your Articles of Organization, you will be asked to appoint an Illinois registered agent.

Your registered agent will be responsible for receiving important legal documents like tax forms and service of process notices on behalf of your LLC. Your registered agent can be an individual resident of the state or a company that’s legally authorized to represent businesses in Illinois.

Illinois does give you the option to act as your own registered agent, but many business owners choose to appoint a professional instead. Here are a few things to think about before you decide to act as your own:

  • You’ll have to maintain normal (9 am - 5 pm) business hours at the address you provide.
  • If you run your business from home, you’ll be required to make your personal address public.
  • You must keep up on important notices, dates, and deadlines.
  • You could be served in front of your family or coworkers.

What To Do:

If you’re considering acting as your own registered agent, do some research, starting with our registered agent guide. If you decide you’re up for the task, go ahead and list your own name and address on your Articles of Organization.

If you’re leaning toward hiring a professional, we recommend doing so through an online LLC formation service. Many of these companies (like Northwest) offer up to one year of registered agent service free when you form your LLC with them. 

 

Step 3) File Articles Of Organization

Register an LLC

Once you’ve decided on your registered agent, you’re ready to officially form your LLC! The next step is to file your Articles of Organization with the Illinois Business Services Division under the Secretary of State's office. You can do this on your own, with the help of a lawyer, or through an online LLC filing service.

What To Do:

File your Articles of Organization online or download the form here. Payment must be made by certified check, cashier’s check, Illinois attorney’s check, C.P.A.’s check or money order payable to Secretary of State.

If you choose to complete this step on your own, you can file either by mail or with the state's online application system. The fee for filing online is $95, while the fee for filing by mail is $100. If you choose to fill out a hard copy of the form, you can download the form here and then send it to the following address:

Secretary of State Business Services Division
302 West Washington Street
Room E018
Indianapolis, IN 46204

If an "Application for Exclusive Use of Corporate Name" form was filed to reserve the name, then it should also be attached to the Articles of Organization.

Processing time is about one hour for online filings and 3 to 4 days by mail.

We recommend that you consider using an LLC formation service. Why? Not only will they take the reins and make sure you file everything properly, but they’ll also provide other necessary products and services at very competitive prices.

One great option is Northwest. In addition to great service, they give you a free year of registered agent service when you sign up.

 

Step 4) Draft An Operating Agreement

Create an Operating AgreementCreating an LLC operating agreement is the only way for you and your members to fully define your roles and lock down your LLC’s management and ownership structure. Having this document in place will also give you all something to return to if a dispute or lawsuit arises.

Your operating agreement should outline the following:

  • each member’s responsibilities
  • how new members will be admitted
  • how existing members may transfer or terminate their membership
  • how profits and dividends are to be distributed

From there, you can add as many provisions as you want, provided they are not in conflict with Illinois business law. To access a free operating agreement and learn more about how this document works in Illinois, click here.

 

Step 5) Get An EIN

Get an EIN for Your LLCThe Employer Identification Number (EIN), or Federal Tax Identification Number, is essentially a social security number for your company. State and federal agencies use this number to track your business activity.

 Your EIN will come in handy when it’s time to:

  • Open a business bank account
  • File Federal and State taxes
  • Hire employees

We think the best way to get an EIN is by using the free online application on the IRS website. We prefer this method because it's the most efficient, but you can apply by phone, fax, or mail. You can read through our guide to find out how.

Maintain Your LLC's Personal Asset Protection

Best Business Bank Account

Using dedicated business banking and credit accounts is essential for personal asset protection.

Now that you’ve made it through the formation process for your LLC, you’ll need to take steps to protect your personal assets and establish your business as an independent entity.

When your personal and business accounts are mixed, your personal assets (your home, car, and other valuables) are at risk in the event your LLC is sued. In business law, this is referred to as piercing your corporate veil.

You can go a long way in protecting your assets with these three steps:

1. Open a business bank account.

A business bank account separates your personal assets from your company's assets, which is necessary for personal asset protection. A designated business bank account also makes accounting and tax filing easier.

2. Get a business credit card.

A business credit card helps you separate personal and business expenses. A business credit card will also build your company's credit history, which can be useful to raise capital later on.

3. Designate an authorized representative.

Make sure all documents are signed by a representative of your LLC and not by you (or other LLC members) directly. This will help separate you from liability incurred by the LLC.

Reduce the Liability of Your LLC

Business Insurance

Business insurance helps you manage risk and focus on growing your business. Carrying the right coverage protects your LLC from liability and keeps you safe in the event of a loss.

The most common types of business insurance are:

  • General Liability Insurance: A broad insurance policy that protects your business from lawsuits. Most small businesses get general liability insurance.
  • Professional Liability Insurance: A business insurance for professional service providers (consultants, accountants, etc.) that covers claims of malpractice and other business errors.

There are free services available that quickly assess your business’s insurance needs. These services suggest customized policies with various insurance carriers so that you can choose the best value. One such reliable service is CoverWallet.

Labor Law

You can reduce your LLC’s liability by being fully compliant with employment laws such as:

  • Verifying new employees are allowed to work in the US.
  • Reporting employees as "new hires" to the state.
  • Withholding employee taxes.
  • Printing compliance posters and placing them in visible areas of your workspace.

If you plan to hire employees, you might also be required to invest in Workers' Compensation Insurance. This type of policy provides coverage for employee job-related illnesses, injuries, or loss of life.

Find out more information on the Illinois Department of Labor website.

Stay Compliant

Business Licenses

As a new LLC, you will need to stay compliant with permits, licenses, taxes, and state filings. This is serious business; failure to comply can lead to fines, tax penalties, and dissolution (the end) of your LLC.

Business Licenses and Permits

To operate your LLC, you must comply with federal, state, and local government regulations. The details of business licenses and permits vary from state to state, so make sure you research carefully and plan accordingly.

Find out how to obtain necessary licenses and permits for your business or have a professional business licensing service do it for you:

Federal: Use the U.S. Small Business Administration (SBA) guide.

State: Use Illinois' Business Services website.

Local: Contact your local county clerk and ask about local licenses and permits.

Sales Tax

If you are selling a physical product, you’ll typically need to register for a seller's permit through the state’s MyTax website.

This certificate allows a business to collect sales tax on taxable sales.

Sales tax, also called "Sales and Use Tax," is a tax levied by states, counties, and municipalities on business transactions involving the exchange of certain taxable goods or services.

Here’s a sales tax guide to find out more.

Employer Taxes

If you have employees in Illinois, you will need to register for Unemployment Insurance Tax and Employee Withholding Tax through the state’s MyTax website.

Annual Report

Illinois requires all LLCs to file an annual report. If you miss state filings like the annual report, you could face fines or even automatic dissolution. A quality registered agent service can help protect your assets by keeping track of filing requirements for you.

Reduce Administrative Burden

There will be many demands on your time once you start your business. With that in mind, it’s a good idea to streamline your workflow and reduce administrative overhead from the get-go. The two most important business tasks to get help with are:

Accounting

Getting your books in order right up front will save you headaches in the future. At the very least, you can have a professional set up your bookkeeping and accounting for you. This will save you money and time in the long run.

There are all-in-one services that will do your bookkeeping/invoicing/tax filing for you all for one monthly fee. Mazuma ($95/month) is a reliable all in one tax service.

Employee Payroll
